Beef tenderloin is the whole long muscle; filet mignon is a small steak cut from its narrow end. Both are tender, lean beef cuts. Cook steaks to 145°F and rest 3 minutes; filet mignon usually costs more per pound.
Beef Tenderloin Vs Filet Mignon comes down to 1 key fact: tenderloin is the whole cut, and filet mignon is one steak cut from it. A tenderloin can be tied and roasted whole or cut into many steaks. Filet mignon is a set, small, thick steak for one plate.
Use tenderloin when you need a roast, cuts, or steaks to feed a group. Pick filet mignon when you want a very tender bite with less chew and a clean round shape. It costs more per pound. Cook all beef steaks or big roasts to 145°F (63°C) and rest 3 minutes.
The Short Answer, With Numbers
Beef tenderloin is the whole muscle. Filet mignon is a steak cut from that muscle, usually from the narrower center or small end.
If you buy 1 whole beef tenderloin, you can cut several filet mignon steaks from it. If you buy 1 filet mignon, you are buying only 1 portion of tenderloin.
| Food | Safe minimum internal temperature | Rest time |
|---|---|---|
| Beef, pork, veal and lamb – steaks, chops, roasts | 145°F (63°C) | 3 minutes |
| Leftovers, reheated | 165°F (74°C) | None |
What the names mean at the butcher counter
A beef tenderloin roast and filet mignon come from the same tender muscle, but they are sold in different formats.
Order “beef tenderloin” and you may get a whole roast, a center-cut roast, or a trimmed tenderloin section. Order “filet mignon” and you get individual steaks.
A filet mignon is not a different animal, grade, or cooking rule. It is a portion cut from beef tenderloin.
Cooking number that matters
For both beef tenderloin roast and filet mignon steaks, the USDA safe minimum internal temperature is 145°F, followed by a 3-minute rest.
That rule applies whether the tenderloin is cooked whole as a roast or sliced into steaks before cooking.
Example: if you roast a center-cut tenderloin, check the thickest part. When it reaches 145°F, remove it from the heat and rest it 3 minutes before slicing.
Example: if you sear 2 filet mignon steaks, check the center of each steak. Each one must reach 145°F and rest 3 minutes.
Portion and cutting math
Filet mignon is the portion-size version. A 2-inch-thick filet is still tenderloin; it is just cut into an individual steak instead of cooked as one larger roast.
If a trimmed tenderloin section is cut into 1-inch steaks, it yields about twice as many steaks as the same section cut into 2-inch steaks.
Example: a 10-inch-long center section gives 10 steaks at 1 inch thick, or 5 steaks at 2 inches thick.
That is why two packages can have the same meat name but different prices per serving: one is a roast meant for slicing later, the other is already portioned.
Edge cases that cause confusion
Chateaubriand is commonly cut from the center of the tenderloin. It is still tenderloin, not a separate safety category.
Tenderloin tips are smaller pieces from the same muscle or trim. If they are intact beef pieces, use the beef steak or roast rule: 145°F plus 3 minutes.
If cooked tenderloin or filet mignon is reheated as leftovers, the relevant number changes to 165°F with no rest time required.
If tenderloin is ground, it is no longer treated like an intact steak or roast. Ground beef uses a different safety rule, but that is not filet mignon.
What Beef Tenderloin Means
Beef tenderloin means the whole long, narrow muscle that runs under the backbone of the steer. It is a primal-area cut, not a single steak.
In U.S. retail butchery, “beef tenderloin” usually refers to the entire trimmed or untrimmed tenderloin, often weighing about 4 to 7 lb before portioning.
The key point: filet mignon comes from beef tenderloin, but beef tenderloin is larger than filet mignon. One tenderloin can produce several filet mignon steaks plus other usable sections.
Where it sits and why it is tender
The tenderloin lies inside the short loin and sirloin area. It does very little work compared with shoulder, brisket, or round muscles.
Less muscle work means less connective tissue. That is why tenderloin is soft, fine-grained, and easy to cut with a fork when cooked properly.
Its tenderness comes with a tradeoff: tenderloin is lean. It has less intramuscular fat than ribeye or strip steak, so it is milder and less beefy.
A whole tenderloin is not perfectly uniform. It has a thick butt end, a more even center section, and a narrow tail end.
The 3 main sections
The butt end is the thickest section. It may include side muscle and uneven seams, so it is often tied, trimmed, or cut into larger steaks or roasts.
The center cut is the most uniform part. This is where classic filet mignon steaks are commonly cut because the diameter is consistent.
The tail tapers sharply. It is usually too small for uniform filet mignon, so it may be folded and tied, cubed for kebabs, or sliced for stir-fry.
Worked example: a 5 lb trimmed tenderloin may yield a 2 lb center-cut roast, 6 steaks at 6 oz each, and about 1 lb of tips, tail pieces, and trim.
Another example: if you cut eight 8 oz steaks, that uses 4 lb of meat. A 6 lb tenderloin still leaves about 2 lb for chateaubriand, tips, or trimmings.
Whole, peeled, and center-cut labels
Whole tenderloin may mean the entire muscle with fat, silverskin, chain, and side muscle still attached. It needs trimming before neat steaks are cut.
Peeled tenderloin usually means much of the outside fat and tough silverskin have been removed. It costs more because less trimming remains.
Center-cut tenderloin means the most even middle portion. It is prized for roasting because it cooks more evenly than the butt or tail.
Chateaubriand is commonly cut from the center tenderloin as a thick roast for 2 to 4 servings, depending on portion size.
Edge case: a “tenderloin roast” may be the whole tenderloin, only the center cut, or a tied piece made from uneven sections. The label should state weight and trim level.
For food safety, beef tenderloin as a steak or roast falls under beef steaks and roasts: cook to 145°F (63°C) and rest for 3 minutes.
What Filet Mignon Means
Filet mignon means a steak cut from the tenderloin, specifically the small, narrow end of that muscle. It is not a separate animal part from beef tenderloin; it is one steak cut within the tenderloin.
On a whole beef tenderloin, the filet mignon comes from the tapered tip end. The larger center section is often sold as tenderloin steaks or Chateaubriand-style roasts, while the thicker butt end may be cut into steaks or roasts.
How big a filet mignon usually is
A typical filet mignon steak is cut 1 1/2 to 2 inches thick. Common retail weights are 6, 8, or 10 ounces per steak. A 2-inch-thick steak may look small in diameter but still weigh 8 ounces.
Example: a butcher trimming a 5-pound whole tenderloin may cut several 6- to 8-ounce filet mignon steaks from the narrow end, several larger center-cut steaks, and a small chain or trim pile for tips.
The word “filet” refers to a boneless cut. “Mignon” means small or delicate. In U.S. meat-counter language, filet mignon usually means an individual tenderloin steak, not the entire tenderloin roast.
Why filet mignon is tender but mild
The tenderloin sits along the spine and does little work, so it has very little connective tissue. That is why filet mignon feels soft and cuts easily with a knife, even when cooked as a thick steak.
The tradeoff is flavor. Filet mignon is leaner and less marbled than ribeye or strip steak. It is prized for texture, not heavy beefiness. Bacon wrapping, butter basting, and pan sauce are common for that reason.
For doneness safety, USDA lists beef steaks at 145°F minimum internal temperature with a 3-minute rest. Measure in the center of the thickest part, not near the edge or pan-seared crust.
When the label can be confusing
If a package says “beef tenderloin steaks,” it may include filet mignon-style steaks, but it may also be center-cut tenderloin steaks. If it says “filet mignon,” expect smaller, rounder steaks from the tenderloin.
Edge case: a very large “filet mignon” may actually be a center-cut tenderloin steak. It can still be tenderloin, but it is not from the tiny tapered end that gives classic filet mignon its small shape.
Another edge case is “petite filet.” This can mean a smaller tenderloin steak, but some stores use it for other lean cuts shaped like filet. Check that the label says beef tenderloin if you want true filet mignon.
A bacon-wrapped filet mignon is still filet mignon if the steak itself is tenderloin. The bacon changes flavor, fat, and cooking behavior, but it does not change the identity of the beef cut.
Practical buying example: for 4 diners wanting moderate portions, buy four 6-ounce filet mignon steaks, totaling 1 1/2 pounds. For steakhouse-size servings, four 8-ounce steaks total 2 pounds.
Compared with buying a whole tenderloin, filet mignon costs more per pound because the butcher has trimmed, portioned, and selected the most uniform small steaks. You pay for convenience and precision.
Key Differences At A Glance
Beef tenderloin is the whole long, tapered muscle. Filet mignon is a steak cut from that muscle, usually from the smaller, narrower end or center. One is the primal-style piece; the other is a portion.
| Point | Beef Tenderloin | Filet Mignon |
|---|---|---|
| What it is | Whole muscle from the loin | Individual steak cut from tenderloin |
| Typical form | Long roast, trimmed or untrimmed | Round steak medallion |
| Common thickness | Roast diameter varies end to end | Often 1.5 to 2 inches thick |
| Best use | Roasting whole or cutting steaks | Pan-searing, grilling, broiling |
| Texture | Very tender throughout, uneven shape | Most consistently tender portion |
| Cooking target | 145°F with 3 minutes rest | 145°F with 3 minutes rest |
Cut Size, Yield, And What You Actually Get
A whole beef tenderloin is not a stack of identical filet mignons. It has a thick butt end, a center-cut section, and a narrow tail. The center gives the neatest steaks; the tail is better for tips or small medallions.
Example: if a trimmed tenderloin is cut into 2-inch steaks, the center may give uniform filets, while the tapered tail may produce pieces that are half the diameter. Those smaller pieces cook faster than the center steaks.
Filet mignon is usually sold as a single steak. If the label says “beef tenderloin steak,” it may be functionally the same cut, but it may come from the butt, center, or tail rather than the most even center portion.
Price And Buying Logic
Filet mignon usually costs more per pound because the butcher has trimmed, portioned, and selected the most presentable pieces. Whole tenderloin often costs less per pound but includes shaping work and some less-uniform meat.
Worked example: buying 4 filet mignon steaks at 8 ounces each gives 2 pounds of neat portions. Buying a 5-pound tenderloin may give several steaks, a roast section, and small end pieces, depending on trim and thickness.
If you need 6 identical plated steaks, filet mignon is the safer buy. If you want flexibility for a roast, steaks, and stir-fry tips, whole beef tenderloin gives more options from one purchase.
Cooking Differences That Matter
Both are lean and mild, so overcooking shows quickly. USDA safe minimum for beef steaks and roasts is 145°F with a 3-minute rest. Use a thermometer in the thickest part.
A whole tenderloin has uneven thickness, so the narrow end can hit temperature before the center. Fold and tie the tail under to make the roast more even, or cut the tail off and cook it separately.
Filet mignon is easier to cook evenly because each steak is compact. Edge case: a bacon-wrapped filet may brown outside before the center reaches temperature, so thermometer placement matters more than color.
Bottom line: tenderloin is the source cut; filet mignon is the premium steak cut from it. Choose tenderloin for yield and flexibility; choose filet mignon for uniform, individual portions.
How To Choose Between Them
Choose filet mignon when you want individual, premium steaks. Choose beef tenderloin when you need flexibility, a roast, or lower cost per serving.
Use this 6-step decision rule
- 1. Count servings first. Filet mignon is usually portioned as 6 to 8 oz steaks. Plan 1 steak per adult. A 3 lb trimmed tenderloin roast gives about 6 servings at 8 oz raw each, or 8 servings at 6 oz raw each.
- 2. Pick the format that matches the meal. For plated steak dinners, buy filet mignon. For slicing at the table, holiday service, or buffet-style eating, buy a whole or center-cut beef tenderloin roast.
- 3. Compare price by edible pound, not package price. If filet mignon is $34/lb and trimmed tenderloin is $28/lb, the tenderloin saves $6 per lb. On 4 lb, that is $24 saved before cooking.
- 4. Factor in trimming and usable yield. A peeled, trimmed tenderloin is close to ready-to-cook. An untrimmed tenderloin may include chain meat, silverskin, and fat. If 5 lb untrimmed yields 4 lb trimmed, your true cost rises by 25%.
- 5. Match thickness to doneness control. Filet mignon cut 1 1/2 to 2 inches thick is easier to sear hard without overcooking. A whole tenderloin has a tapered tail, so the thin end cooks faster than the center.
- 6. Decide whether leftovers matter. Filet mignon is best when served immediately. Tenderloin roast slices cleanly for next-day sandwiches, salads, and platters. Reheated leftovers should reach 165°F.
Worked buying examples
For 2 people, buy two 6 to 8 oz filet mignon steaks. That is 12 to 16 oz total, with no carving and very little waste.
For 6 people, buy a 3 lb trimmed beef tenderloin roast if serving 8 oz raw portions. If sides are heavy, 2 1/4 to 2 1/2 lb can work at 6 to 7 oz raw per guest.
For 10 people, a 5 lb trimmed tenderloin is the cleanest choice. Cutting ten individual filets is possible, but it costs more and requires more pan or grill space.
If your butcher offers a whole tenderloin and a center-cut tenderloin, choose center-cut for even slices. Choose whole tenderloin if you want filets, roast portions, and stir-fry or kebab trim from one purchase.
If you need perfectly uniform presentation, filet mignon wins. Each steak can be cut to the same weight and thickness. A whole tenderloin gives larger center slices and smaller end slices.
If tenderness is the only priority, both are excellent because filet mignon comes from the tenderloin. The difference is shape, portioning, cost, and cooking control, not a different muscle.
Cook beef tenderloin steaks, chops, or roasts to 145°F with a 3-minute rest. Use an instant-read thermometer in the thickest part, especially on a roast with uneven ends.
Best Uses For Each Cut
Use beef tenderloin when you need a roast or multiple portions. Use filet mignon when you want individual steaks with exact portion control, fast cooking, and a plated, restaurant-style center-of-plate item.
A whole beef tenderloin is best for 6 to 12 servings. A trimmed tenderloin often runs about 4 to 6 pounds, so it works for holidays, buffets, and dinner parties where slicing at the table is useful.
Filet mignon is the steak cut from the tenderloin. Common portions are 6, 8, or 10 ounces. Choose it when each guest should get the same thickness, same doneness range, and same presentation.
Best Uses For Whole Beef Tenderloin
Roast a whole tenderloin when appearance matters and carving is part of the meal. It gives clean, round slices and very little connective tissue, so guests do not need steak knives as much as with ribeye or strip.
For 8 guests, buy about a 4-pound trimmed tenderloin if it is the main protein. That gives roughly 8 ounces raw per person before cooking loss, or smaller plated portions if you serve rich sides.
For 12 guests, a 5- to 6-pound trimmed tenderloin is more realistic. If the menu includes shrimp, ham, or heavy appetizers, 4 to 5 pounds can work because each serving can be thinner.
Tenderloin is also the better choice for Beef Wellington. The even cylinder shape fits pastry neatly, and the lean texture pairs well with mushroom duxelles, prosciutto, or pâté without becoming greasy.
Edge case: if the tenderloin has a thin tail, fold and tie that end under itself. Otherwise the tail overcooks before the center is done. Tying at 1- to 2-inch intervals keeps slices round.
For food safety, beef roasts should reach 145°F and rest 3 minutes. That applies to beef tenderloin roast because it is a whole-muscle beef roast.
Best Uses For Filet Mignon
Filet mignon is best for date nights, small dinner parties, surf and turf, and steakhouse plates. It cooks quickly because each steak is compact, usually 1 1/2 to 2 inches thick.
Use 6-ounce filets for lighter plates or menus with lobster, crab cakes, or creamy potatoes. Use 8-ounce filets for a standard steakhouse portion. Use 10-ounce filets for very hearty appetites.
Filet mignon is ideal when you want a sauce-forward steak. Its mild beef flavor works with béarnaise, red wine reduction, peppercorn sauce, compound butter, or blue cheese without clashing.
It is not the best cut for high-volume grilling if budget matters. Buying 10 individual filets usually costs more than buying one tenderloin and portioning it yourself.
Worked example: from a 5-pound trimmed tenderloin, cutting ten 8-ounce steaks uses the full 80 ounces. In practice, expect a few center-cut filets, some smaller end steaks, and a tail piece for tips.
For food safety, beef steaks should reach 145°F and rest 3 minutes. That applies to filet mignon because it is a beef steak cut from the tenderloin.
Quick Decision Guide
| Goal | Better Pick | Why |
|---|---|---|
| Holiday roast for 8 to 12 | Beef tenderloin | Carves cleanly and feeds a group from one roast |
| Two-person steak dinner | Filet mignon | Exact portions and fast cooking |
| Lowest waste | Filet mignon | Buy only the number of steaks needed |
| Best value per serving | Whole tenderloin | Usually cheaper than buying center-cut filets individually |
| Beef Wellington | Beef tenderloin | Uniform roast shape fits pastry |
Doneness And Temperature Guide
Beef tenderloin and filet mignon come from the same muscle, so the doneness targets are the same. The difference is timing: a whole tenderloin rises more after cooking than a 1 1/2- to 2-inch filet.
Target Temperatures
Use an instant-read thermometer in the thickest center point. For food safety, USDA guidance is 145°F with a 3-minute rest. Many cooks pull below that for rarer beef, but that is a preference choice.
Rare: pull at 120°F to 125°F; final temperature about 125°F to 130°F. Medium-rare: pull at 125°F to 130°F; final about 130°F to 135°F.
Medium: pull at 135°F to 140°F; final about 140°F to 145°F. Medium-well: pull at 145°F to 150°F; final about 150°F to 155°F. Well-done: final temperature is 160°F or higher.
Carryover Heat: Roast Vs Steak
A whole beef tenderloin usually gains 5°F to 10°F while resting because its mass holds heat. A filet mignon steak usually gains 3°F to 5°F, depending on thickness and pan heat.
Worked example: if you want a whole tenderloin at 135°F medium-rare, pull it from the oven at 127°F to 130°F. Rest 10 to 15 minutes, then slice after the center reaches about 135°F.
Worked example: if you want a 2-inch filet at 130°F, remove it from the skillet at 125°F to 127°F. Rest 5 to 8 minutes. The final center temperature should land near 130°F.
Where To Measure
For a tenderloin roast, check the thick center, not the tapered tail. If one end is thinner, fold and tie it, or expect that section to finish 5°F to 15°F hotter than the center.
For filet mignon, insert the probe from the side toward the center. On a 1 1/2-inch steak, the tip should sit about 3/4 inch in, halfway between the top and bottom surfaces.
Resting And Slicing
Rest filet mignon 5 to 8 minutes. Rest a whole tenderloin 10 to 15 minutes. Cutting immediately can spill juices and drop the serving temperature by several degrees.
Slice tenderloin into 1/2- to 1-inch medallions. Serve filet mignon whole, or halve it only after resting so the center temperature stabilizes before it reaches the plate.
Price And Yield Considerations
Beef tenderloin is usually priced by the pound as a whole roast, while filet mignon is priced as trimmed steaks. The tenderloin looks cheaper per pound, but the real comparison is edible, steak-ready yield.
Yield Changes The True Cost
A whole tenderloin may include chain muscle, silverskin, surface fat, and a tapered tail. After trimming, expect roughly 65% to 75% steak-ready meat if it was not already peeled and trimmed.
Worked example: a 6 lb whole tenderloin at $19.99/lb costs $119.94. At 70% yield, it gives 4.2 lb of usable center-cut and medallion meat. The true trimmed cost is $119.94 ÷ 4.2, or $28.56/lb.
If the butcher’s filet mignon is $34.99/lb, the whole tenderloin saves $6.43 per usable pound in that example. On 4.2 lb of finished meat, that is about $27.01 saved.
Portion Math For Filet Mignon
A 6 oz filet is 0.375 lb. At $34.99/lb, one 6 oz steak costs $13.12. An 8 oz filet is 0.5 lb, so the same price gives a per-steak cost of $17.50.
From 4.2 lb of usable trimmed tenderloin, you can cut eleven 6 oz portions, with about 0.075 lb left, or eight 8 oz portions plus 0.2 lb for tips or stir-fry.
Center-cut steaks command the highest price because they are uniform. The head and tail are still tender but may produce smaller tournedos, skewers, tips, or a tied mini-roast rather than perfect filets.
When Filet Mignon Is Worth Paying For
Buy filet mignon when you need exact portions, no trimming time, and no waste. For 4 guests eating 8 oz each, you need 2 lb. At $34.99/lb, the meat bill is $69.98.
Buy a whole tenderloin when feeding more people or when you can use trim. If the trimmed true cost is below the filet price by at least $5/lb, the savings are usually meaningful.
Storage And Freezing Advice
Beef tenderloin and filet mignon need the same food-safety rules, but their shape changes how fast they dry out. Keep both at 40°F or below in the refrigerator and at 0°F or below in the freezer.
Refrigerating Raw Tenderloin And Filet Mignon
Raw beef steaks and roasts keep 3 to 5 days in the refrigerator. That means a whole tenderloin bought Monday should be cooked or frozen by Saturday at the latest.
Filet mignon steaks are cut surfaces on all sides, so wrap them tightly. Keep butcher paper only if cooking within 1 day. For longer storage, rewrap in plastic wrap plus foil or use a sealed bag.
A whole tenderloin has less exposed surface area than 4 separate filets, so it usually resists drying better. Still, place it on a rimmed tray to catch any juices and store it on the lowest shelf.
Freezing For Best Quality
For best quality, freeze raw steaks or roasts for 4 to 12 months. A 5-pound whole tenderloin frozen on January 1 is best used by May 1 to January 1 of the next year.
Filet mignon freezes well when wrapped individually. Example: wrap each 8-ounce filet tightly, then place 4 wrapped steaks in one labeled freezer bag. This lets you thaw only 1 or 2 portions.
Use freezer labels with the cut, weight, and date. Write “filet mignon, 8 oz, 3/10” or “whole tenderloin, 4 lb 8 oz, 3/10” so portions and age are clear.
Cooked Beef Storage
Cooked beef tenderloin or filet mignon keeps 3 to 4 days in the refrigerator. If cooked on Thursday, use leftovers by Monday. Freeze cooked beef for best quality within 2 to 3 months.
Refrigerate cooked beef within 2 hours of cooking. If the room or outdoor temperature is above 90°F, refrigerate within 1 hour. Slice leftovers only after chilling if you want to reduce drying.
Thawing And Refreezing
Thaw frozen tenderloin or filet mignon in the refrigerator, not on the counter. A thick whole tenderloin takes longer than individual filets, so plan ahead and keep it on a tray while thawing.
Beef thawed in the refrigerator can be refrozen without cooking, but quality may decline. Beef thawed in cold water or the microwave should be cooked before refreezing.

People Also Ask
What is the difference between beef tenderloin and filet mignon?
Beef tenderloin is the whole long, lean muscle from the loin. Filet mignon is a steak cut from the smaller, narrower end of that tenderloin. In short: tenderloin is the larger cut; filet mignon is usually a 1- to 2-inch-thick portion of it.
Is filet mignon more tender than beef tenderloin?
Filet mignon is cut from beef tenderloin, so both are very tender. The filet often feels slightly more luxurious because it is cut from the most uniform, center-to-small end portions.
A whole tenderloin includes thicker and thinner sections, so texture can vary more across the roast.
Which costs more, beef tenderloin or filet mignon?
Filet mignon usually costs more per pound because it is portioned into premium steaks and trimmed for presentation. Whole beef tenderloin often has a lower per-pound price, but you buy several pounds at once and may pay for some trimming loss.
Should I buy beef tenderloin or filet mignon for a dinner party?
Choose whole beef tenderloin for serving a group because one roast can feed several people evenly. Choose filet mignon when you want individual steaks, precise portions, and a steakhouse-style plate. Plan about 6 to 8 ounces of trimmed beef per adult.
Use a food thermometer in the thickest part, not color alone, because tenderloin can look pink after reaching temperature.
Is beef tenderloin the same cut as filet mignon?
Filet mignon comes from beef tenderloin, but the terms are not identical. Beef tenderloin is the whole long muscle, while filet mignon is a steak cut from the narrower, especially prized end. Other tenderloin steaks may be labeled tenderloin steak or chateaubriand-style portions.
What internal temperature should beef tenderloin or filet mignon reach?
USDA recommends cooking whole beef cuts to an internal temperature of 145°F followed by a 3-minute rest. Many cooks remove tenderloin or filet mignon before the final target because carryover heat continues cooking. Always check the thickest part with an instant-read thermometer.
Do beef tenderloin and filet mignon need a marinade?
Neither cut usually needs a marinade for tenderness because both come from a very tender muscle. Use salt, pepper, butter, herbs, or a pan sauce instead. If marinating for flavor, avoid long acidic marinades, which can make the surface mushy rather than improving the meat.
