Tenderloin steak comes from the whole beef tenderloin; filet mignon is the small, most tender steak cut from its narrow end. Cook either like steak to 145°F and rest 3 minutes; filet mignon is usually thicker, pricier, and milder.
Tenderloin Steak Vs Filet Mignon: 1 main difference—filet mignon is a specific small steak cut from the narrow end of the beef tenderloin, while tenderloin steak can mean any steak cut from that whole tenderloin muscle.
Expect filet mignon to be the most uniform, thick, and premium portion. Other tenderloin steaks may be larger or less even but still very tender. For food safety, cook beef steaks to 145°F (63°C) and rest 3 minutes.
The Short Answer, With Numbers
Tenderloin steak and filet mignon are not opposites. Filet mignon is a specific steak cut from the beef tenderloin, usually from the narrower, most delicate end.
The tenderloin is the whole long muscle. A butcher can cut it into multiple steaks. Filet mignon is one of those steaks, prized because it is thick, lean, and very tender.
Key figures for cooking and naming
| Item | What it means | Safe minimum internal temperature | Rest time |
|---|---|---|---|
| Beef tenderloin steak | A steak cut from the tenderloin muscle | 145°F (63°C) | 3 minutes |
| Filet mignon | A specific tenderloin steak, usually from the smaller end | 145°F (63°C) | 3 minutes |
| Leftover cooked tenderloin or filet mignon | Cooked steak being reheated | 165°F (74°C) | None |
For food safety, both are treated the same: cook beef steaks, chops, and roasts to 145°F, then rest for 3 minutes.
Example: if you buy a whole beef tenderloin and cut it into 8 steaks, the center-cut pieces may be sold as tenderloin steaks. The smaller, rounder end pieces are often labeled filet mignon.
Example: if a menu says “8 oz filet mignon,” it is telling you the cut and portion size. If it says “8 oz tenderloin steak,” it may be the same muscle, but not necessarily the classic small-end filet.
The practical difference is shape and source within the muscle. Filet mignon is usually more uniform, compact, and round. Tenderloin steak is a broader label and can include center-cut or end-cut portions.
Price often follows precision. A package labeled “filet mignon” is usually priced higher than a generic “tenderloin steak” because it signals a specific, premium portion.
Texture is similar because both come from the same low-work muscle. Neither has the heavy marbling of ribeye. Expect tenderness first, beefy fat flavor second.
Worked cooking target: pull the steak only when the center reaches the required 145°F, then rest it for 3 minutes. The rule is identical for filet mignon and tenderloin steak.
Edge case: bacon-wrapped filet mignon is still a beef steak for the center temperature. Measure the beef center with a food thermometer; the safe steak figure is 145°F with a 3-minute rest.
Edge case: stuffed or assembled beef dishes can change the category. If the dish is a casserole containing meat, the relevant safe minimum is 165°F with no rest time.
Edge case: reheating yesterday’s cooked filet or tenderloin is not the same as cooking a fresh steak. Reheated leftovers should reach 165°F.
Bottom line: all filet mignon is tenderloin, but not every tenderloin steak is filet mignon. For safety, fresh beef steak is 145°F plus 3 minutes; leftovers are 165°F.
Tenderloin And Filet Mignon Compared
Tenderloin is the whole long, narrow muscle from the loin of beef. Filet mignon is a steak cut from that tenderloin, usually from the smaller center or forward end.
In practical buying terms: tenderloin is the parent cut; filet mignon is one portion cut from it. A butcher can cut 6 to 12 filet mignon steaks from one trimmed tenderloin, depending on steak thickness.
| Item | What it means | Typical size | Best use |
|---|---|---|---|
| Tenderloin | Whole muscle or large roast | About 4 to 6 lb whole, trimmed weight varies | Roast whole, cut into steaks, Beef Wellington |
| Filet mignon | Individual steak from tenderloin | Usually 1 1/2 to 2 inches thick | Pan-sear, grill, broil |
| Chateaubriand-style center cut | Thick center section of tenderloin | Often 1 1/2 to 3 lb | Roast for 2 to 4 servings |
Where The Steak Comes From
The tenderloin tapers. The thick middle gives the most even, round steaks. The narrow tail gives smaller medallions. The butt end can be wider and may include seams or side muscle.
Filet mignon is usually cut 1 1/2 to 2 inches thick because the steak is small in diameter. A 1-inch filet can overcook quickly before a browned crust forms.
Example: a 5 lb trimmed tenderloin cut into 8 steaks gives average 10 oz portions. If cut into 10 steaks, the average falls to 8 oz. Thicker steaks mean fewer servings.
Texture, Flavor, And Fat
Tenderloin is prized for tenderness because the muscle does little work. It has very fine grain and low connective tissue. That is why filet mignon cuts easily with a fork.
The tradeoff is flavor. Ribeye and strip have more marbling and beefy taste. Filet mignon is milder, so restaurants often add butter, bacon, sauce, mushrooms, or a hard sear.
Edge case: a “bacon-wrapped filet” is still filet mignon, but the bacon adds fat and smoke. It also changes cooking behavior because the sides are insulated.
Cooking And Doneness Rules
For beef steaks, the USDA safe minimum internal temperature is 145°F followed by a 3-minute rest. Measure in the center with a food thermometer.
A 2-inch filet is easy to brown outside while keeping the center controlled. A thin 1-inch tenderloin steak has less margin; 1 extra minute per side can noticeably change doneness.
Worked example: cut a center tenderloin roast into four 2-inch steaks and two tail medallions. Cook the medallions separately; they may finish faster than the thick center steaks.
Buying: Which Should You Choose?
Buy whole tenderloin when you want control over thickness and portions. It is useful for holidays because one roast can serve a group evenly when sliced after cooking.
Buy filet mignon when you want trimmed, individual steaks with no butchering. You pay more per pound because trimming, portioning, and the most uniform center cuts are already done.
If a label says “tenderloin steak,” it may be filet-style but not necessarily center-cut filet mignon. Check shape: center filets are round and even; tail cuts are smaller or oval.
For two people, two 6 to 8 oz filets are straightforward. For six people, a 3 lb center-cut tenderloin roast allows about 8 oz raw weight per person before cooking loss.
Where Each Cut Comes From
Tenderloin steak and filet mignon come from the same muscle: the beef tenderloin. The difference is size and location. “Tenderloin steak” can mean a steak cut from almost any part of that muscle.
Filet mignon is narrower. In U.S. butcher use, it usually means medallions cut from the small, forward end of the tenderloin, often called the tip or tapered end.
The tenderloin: the whole source muscle
The tenderloin is the long, soft muscle that runs inside the loin, along the backbone. It sits beneath the ribs and spine, spanning the short loin and sirloin sections.
On a side of beef, there is 1 tenderloin. A whole beef has 2 tenderloins. Each is an elongated muscle, thick at the butt end, even through the center, and narrow at the tip.
A trimmed whole tenderloin commonly yields several zones: the butt end, the center-cut section, the chain or side muscle, and the tapered tip. Steaks may be cut from more than one of these zones.
| Cut name | Where it comes from | Typical shape |
|---|---|---|
| Tenderloin steak | Any steak cut from the tenderloin muscle | Round, oval, or slightly irregular |
| Filet mignon | Usually the small end or premium center medallions | Small, round, thick medallion |
| Chateaubriand | Center-cut tenderloin roast | Thick, even roast section |
| Tournedos | Small tenderloin medallions | Thin-to-thick round portions |
Worked example: one whole tenderloin
Suppose a trimmed tenderloin is divided into 3 usable steak zones: a 2-inch-wide tip, a 10-inch center section, and a 4-inch butt end. The center gives the most uniform steaks.
If the center section is cut into 2-inch steaks, it yields about 5 center-cut tenderloin steaks. These may be sold as filet mignon if they are small, round, and high-grade in presentation.
The 2-inch tip may be too narrow for a full steak. A butcher may fold it, tie it, cut it into small medallions, or use it for kabobs, tips, or sauté pieces.
The 4-inch butt end can produce 2 thick steaks, but they may be wider or less round. These are still tenderloin steaks, though many shops avoid labeling the odd-shaped pieces as filet mignon.
Key edge cases at the meat counter
A “filet” on a menu may be a tenderloin steak from the center, not strictly the tiny tip. Restaurants often use “filet mignon” for any neat, thick tenderloin medallion.
A “beef tenderloin steak” may be excellent but slightly larger, flatter, or cut from the butt end. It is not a lower muscle; it is the same tenderloin, just a different section.
A T-bone or porterhouse includes tenderloin on one side of the bone. That tenderloin portion is the same muscle, but it is not usually called filet mignon until removed and portioned.
The practical rule: all filet mignon is tenderloin, but not every tenderloin steak is sold as filet mignon. Location, shape, thickness, and trimming decide the label.
Key Differences In Taste And Texture
Filet mignon is a cut from the tenderloin, not a different muscle. The taste and texture gap comes from location, size, trimming, and thickness.
A whole beef tenderloin is the long, tapered muscle under the backbone. Filet mignon usually comes from the smaller, center-to-front steaks cut from that muscle, often 1.5 to 2.5 inches thick.
Texture: Filet Mignon Is Usually More Uniform
Filet mignon is prized because it is consistently soft from edge to center. It has very little connective tissue and short, fine muscle fibers, so a knife slides through with little resistance.
Tenderloin steak can be just as tender, but the term is broader. It may include butt-end, center-cut, or tail-end steaks. Those pieces can vary more in shape, thickness, and chew.
| Cut | Typical Texture | Common Size | Practical Result |
|---|---|---|---|
| Filet mignon | Very soft, fine-grained, even | 6 to 10 oz | Best for a fork-tender steak |
| Center-cut tenderloin steak | Nearly identical to filet | 6 to 12 oz | Often the best value substitute |
| Butt-end tenderloin steak | Tender but less uniform | 8 to 14 oz | May have seams or uneven edges |
| Tail-end tenderloin steak | Tender but thin and tapered | 4 to 8 oz | Easy to overcook at the narrow end |
Taste: Both Are Mild, But Filet Can Taste Less Beefy
Both cuts are lean compared with ribeye or strip steak. That means less intramuscular fat and a milder beef flavor. Filet mignon often tastes buttery and clean rather than bold.
A tenderloin steak from the butt end may taste slightly beefier because it can have more exterior fat, seams, or surface browning area after trimming. The difference is subtle, not dramatic.
Worked example: a 2-inch, 8 oz filet has a thick center and small surface area. It gives a soft, juicy bite but less crust per ounce. A 1-inch, 8 oz tenderloin steak has more surface area and more browned flavor.
That crust-to-meat ratio matters. If two steaks weigh 8 oz, the thinner one usually tastes more savory because more of each bite includes browned exterior.
Edge Cases That Change The Eating Experience
A bacon-wrapped filet mignon tastes saltier and smokier than plain tenderloin. The bacon adds fat, but it also hides the naturally mild flavor of the beef.
A tournedos-style tenderloin medallion may be only 1 to 1.25 inches thick. It can be tender, but it will not feel as plush as a 2-inch filet because it cooks through faster.
A chateaubriand is a thick center-cut tenderloin roast, often sliced after cooking. Its texture can match filet mignon, but the slices have less seared surface than individual steaks.
For safety, beef tenderloin steaks and filet mignon steaks should reach 145°F and rest for 3 minutes. Use a thermometer in the thickest part, especially on 2-inch cuts.
Bottom line: filet mignon is the most consistently tender, mild, and luxurious tenderloin steak. Other tenderloin steaks can match it, but shape and trimming create more variation.
How To Choose The Right Cut
Fast answer: choose filet mignon when you want a small, ultra-tender center-cut steak. Choose tenderloin steak when you want the same muscle at a lower price, more size options, or pieces for searing, roasting, or slicing.
Use These 6 Buying Steps
- 1. Decide whether tenderness or value matters more. Filet mignon is cut from the most uniform, center portion of the tenderloin. It is usually the most tender and most expensive option.
- 2. Price it per edible ounce, not per package. If filet mignon is $34.99/lb and tenderloin steak is $24.99/lb, the filet costs about $2.19/oz. The tenderloin costs about $1.56/oz.
- 3. Match thickness to your cooking method. For pan-searing, buy steaks 1 1/2 to 2 inches thick. Thin 1-inch tenderloin steaks can overcook fast because the cut has little fat insulation.
- 4. Choose filet mignon for plated steaks. For 2 guests, buy two 6- to 8-ounce filets. That gives each person a neat individual steak with minimal trimming and a consistent round shape.
- 5. Choose tenderloin steak for flexible meals. Buy 1 1/2 pounds of tenderloin steaks to serve 3 to 4 people when slicing over salad, pasta, rice bowls, or crostini.
- 6. Check the cut location if the label is vague. Center-cut pieces are round, even, and thick. Tail-end pieces are narrower and cook unevenly, but they are useful for kebabs, tips, or quick sautéing.
When Filet Mignon Is Worth The Upgrade
Pick filet mignon for anniversaries, steakhouse-style plates, or meals where each person gets one steak. The shape matters because a 2-inch-thick filet sears well without drying out as quickly as a thin cut.
A practical serving is 6 ounces per person for a rich meal with sides. For 4 people, buy four 6-ounce filets, or 1 1/2 pounds total. If you want leftovers, move to 8 ounces each.
Filet mignon is also the better choice when presentation matters. Its round, compact shape fits a plate cleanly and cooks more evenly than tapered tenderloin tail pieces.
When Tenderloin Steak Is The Smarter Buy
Choose tenderloin steak when the label includes center-cut medallions, tournedos, butt-end steaks, or tail pieces. They come from the tenderloin but are not always the premium filet portion.
For a worked example, assume you need 24 ounces of steak. At $34.99/lb, filet mignon costs about $52.48. At $24.99/lb, tenderloin steak costs about $37.49. The savings are about $14.99.
Use those savings when the steak will be sliced, sauced, wrapped in bacon, or served with strong sides. In those cases, the exact filet shape is less important than tenderness.
Edge Cases At The Meat Counter
If the steak is labeled “beef tenderloin filet,” treat it like filet mignon if it is center-cut, round, and evenly thick. If it is tapered or irregular, treat it as tenderloin steak.
If buying a whole tenderloin, expect multiple sections: center-cut filets, thicker butt-end pieces, and narrow tail. The center is best for filet mignon; the tail is best for tips or stir-fry.
For food safety, cook beef tenderloin steaks, including filet mignon, to 145°F and let them rest 3 minutes before serving.
Best Ways To Cook Each Cut
Filet mignon is best cooked fast and hot. It is a small steak cut from the tenderloin, usually 1 1/2 to 2 inches thick and 6 to 10 ounces.
Whole tenderloin is best roasted more gently. It is larger, often 2 to 5 pounds, and needs even heat so the narrow tail and thick center do not overcook.
Filet Mignon: Sear, Then Finish Briefly
For a 2-inch filet, use a heavy skillet. Preheat the pan for 3 to 5 minutes, then add 1 tablespoon high-heat oil. Sear the steak 2 minutes per side.
After searing, move the skillet to a 400°F oven for about 4 to 7 minutes, depending on thickness. A 1 1/2-inch filet may need 4 minutes; a 2-inch filet may need 6 to 7.
For food safety, beef steaks should reach 145°F and rest 3 minutes. Measure in the center from the side, not from the top, to avoid a false reading.
Because filet mignon is lean, butter helps. Add 1 tablespoon butter, 1 smashed garlic clove, and thyme during the final minute of stovetop cooking, then spoon the butter over the steak.
A bacon-wrapped filet needs extra attention. The bacon may brown before the center is ready. Sear the top and bottom first, then roll the side edge in the pan for 60 to 90 seconds.
Whole Tenderloin: Roast Evenly, Then Slice
Trim silver skin first. It is tough and does not melt. Use a thin knife, angle it slightly upward, and remove the shiny strip without cutting deeply into the meat.
Tie the tenderloin every 1 1/2 to 2 inches with kitchen twine. Fold the thin tail under before tying so the roast has a more uniform diameter.
For a 3-pound tenderloin, season with 2 teaspoons kosher salt and 1 teaspoon black pepper. Let it stand 30 minutes before cooking for better surface browning.
Roast at 425°F on a rack in a shallow pan. A 2-pound roast may take about 25 to 30 minutes; a 4-pound roast may take about 35 to 45 minutes.
Use the thermometer in the thickest center section. For safety, beef roasts should reach 145°F and rest 3 minutes.
For a more browned crust, sear the whole tenderloin first. Use a large skillet or griddle and brown 2 minutes per side, turning until all exposed sides are seared.
Which Method Fits Which Cut?
| Cut | Best method | Typical size | Key move |
|---|---|---|---|
| Filet mignon | Pan sear plus oven finish | 6 to 10 oz | Sear hard, avoid overcooking |
| Whole tenderloin | Tie, roast, slice | 2 to 5 lb | Fold tail under for even cooking |
| Tenderloin medallions | Quick skillet cook | 1 to 1 1/2 inches thick | Cook in one layer, not crowded |
If cooking mixed thicknesses, remove thinner filet mignon pieces first. For a whole tenderloin, check the tail and center separately; the tail can run hotter than the middle.
Do not treat tenderloin like ribeye. It has less fat, so long grilling or repeated flipping over high heat can dry it out. Precise timing matters more than heavy charring.
Frequently Asked Questions
Is tenderloin steak the same as filet mignon?
Not exactly. Tenderloin is the whole long, narrow muscle from the loin. Filet mignon is a specific steak cut from the smaller, most tender end of that tenderloin. So every filet mignon is tenderloin, but not every tenderloin steak is filet mignon.
Which is more tender, tenderloin steak or filet mignon?
Filet mignon is usually the most tender because it comes from the narrow tip of the tenderloin, a muscle that does very little work. Other tenderloin steaks are also very tender, but they may be slightly larger, thicker, or less uniform.
Which costs more, filet mignon or tenderloin steak?
Filet mignon usually costs more per pound because it is cut from the smallest, most prized section of the tenderloin. Whole tenderloin or center-cut tenderloin steaks can be cheaper per serving, especially if you trim and portion the roast yourself.
Do tenderloin steak and filet mignon taste different?
They taste very similar because both come from the same tenderloin muscle. Filet mignon is prized for texture more than beefy flavor. Compared with ribeye or strip steak, both are leaner and milder, so salt, butter, sauce, or bacon wrapping is common.
What temperature should tenderloin steak or filet mignon be cooked to?
USDA lists beef steaks, chops, and roasts at 145°F internal temperature with a 3-minute rest. That applies to tenderloin steak and filet mignon. Use a food thermometer in the thickest part instead of judging doneness by color alone.
