Cook pork tenderloin at 375°F for about 25–30 minutes for a 1-pound tenderloin, until the thickest part reaches 145°F. Rest it for 3 minutes before slicing; thicker tenderloins may need about 5–10 minutes more.
How Long To Cook Pork Tenderloin In The Oven At 375: cook a 1-pound pork tenderloin for about 25 minutes, then check that the center reaches 145°F (63°C) and rest it 3 minutes.
For most trimmed pork tenderloins, plan on 20 to 30 minutes at 375°F, depending on thickness and starting temperature. Use an instant-read thermometer in the thickest part; the time is only a guide, but 145°F plus a 3-minute rest is the doneness target.
The Short Answer, With Numbers
At 375°F, a pork tenderloin usually takes 20 to 30 minutes in the oven, depending on thickness, starting temperature, and whether you sear it first.
Pull it when the thickest center reaches 145°F, then rest it for 3 minutes. That temperature and rest apply to pork roasts, which includes pork 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 |
375°F Pork Tenderloin Timing
For a typical 1-pound pork tenderloin, plan on about 22 to 25 minutes at 375°F if it goes into the oven raw and unseared.
For a larger 1 1/2-pound tenderloin, expect roughly 25 to 30 minutes. If it is thick in the center, use the high end of that range.
If you sear the tenderloin first in a hot skillet for 2 to 3 minutes per side, oven time often drops to about 15 to 22 minutes at 375°F.
A very narrow tenderloin can finish in 18 to 20 minutes. A thick, cold tenderloin taken straight from the refrigerator may need closer to 30 minutes.
Start checking with an instant-read thermometer at 18 minutes for a small tenderloin and at 22 minutes for a larger one.
Worked Examples
Example 1: A 1-pound tenderloin, not seared, roasted at 375°F: check at 20 minutes. It will commonly finish around 22 to 25 minutes.
Example 2: A 1 1/4-pound tenderloin, seared first for 2 minutes per side: roast at 375°F and check at 15 minutes. Expect about 18 to 22 minutes in the oven.
Example 3: Two tenderloins on one pan: cook by thickness, not total weight. If they are not touching, the time is usually similar to one tenderloin.
If the two tenderloins are crowded, touching, or packed tightly with vegetables, add time and check the center of each piece separately.
The thermometer tip should go into the thickest part from the side, not straight down into a thin edge. Avoid touching the pan, fat pocket, or any stuffing.
After the pork reaches 145°F, move it to a board and rest it for 3 minutes. Slice after the rest so the juices settle instead of running out.
For reheated pork tenderloin leftovers, the relevant figure is different: reheat leftovers to 165°F. The table above lists that separately.
375 Degree Cook Time
At 375°F, pork tenderloin usually takes 20 to 30 minutes in the oven, depending on weight, thickness, pan type, and whether it was seared first.
Cook pork tenderloin to 145°F in the thickest part, then rest it for 3 minutes. That rest is required for whole pork cuts such as roasts.
Time By Tenderloin Size
| Pork tenderloin size | Oven time at 375°F | Best pull point |
|---|---|---|
| ¾ lb | 18 to 22 minutes | 145°F, then 3-minute rest |
| 1 lb | 22 to 26 minutes | 145°F, then 3-minute rest |
| 1¼ lb | 25 to 30 minutes | 145°F, then 3-minute rest |
| 1½ lb | 30 to 35 minutes | 145°F, then 3-minute rest |
A typical grocery-store pork tenderloin is about 1 to 1¼ lb. At 375°F, plan on 22 to 30 minutes, then verify with a thermometer.
Start checking early. For a 1 lb tenderloin, check at 20 minutes. For a 1¼ lb tenderloin, check at 24 minutes. For a 1½ lb tenderloin, check at 28 minutes.
Worked Examples
Example 1: A 1 lb tenderloin, seared first, goes into a 375°F oven. Check at 20 minutes. It often reaches 145°F around 22 to 24 minutes.
Example 2: A 1¼ lb tenderloin, not seared, baked on a sheet pan. Start checking at 24 minutes. Expect about 26 to 30 minutes.
Example 3: Two 1 lb tenderloins on one pan do not take 44 to 52 minutes. If spaced apart, they usually take about 24 to 30 minutes.
If the tenderloins touch each other, cooking slows. Leave at least 1 inch between pieces so hot air can circulate around the sides.
Searing Vs. No Searing
If you sear the pork for 2 minutes per side before baking, the oven time usually drops by 3 to 6 minutes.
A seared 1 lb tenderloin may finish in 20 to 24 minutes at 375°F. An unseared 1 lb tenderloin usually needs 22 to 26 minutes.
Use a rimmed sheet pan, roasting pan, or oven-safe skillet. A cold glass dish can add a few minutes because it heats more slowly than metal.
Stuffed, Wrapped, Or Sauced Tenderloin
A stuffed pork tenderloin is not the same as a plain one. If it is thickly filled and tied, expect about 30 to 40 minutes at 375°F, depending on diameter.
Bacon-wrapped tenderloin often needs 28 to 38 minutes. The bacon insulates the pork, so the center may lag even when the outside looks browned.
Heavy sauces, glazes, or foil covers can slow browning. If covered with foil, uncover for the last 8 to 10 minutes to improve color.
When To Pull It From The Oven
Insert the thermometer into the thickest center section, not the tapered end. The skinny end can read done while the middle is still lower.
Remove the tenderloin when the thickest part reads 145°F. Let it rest 3 minutes before slicing.
For cleaner slices, rest the pork on a cutting board, then cut across the grain into ½-inch slices. A 1 lb tenderloin usually gives 4 servings.
Time By Tenderloin Size
At 375°F, pork tenderloin usually takes 20 to 35 minutes, depending mostly on weight and thickness. Pull it when the thickest part reaches 145°F, then rest 3 minutes.
375°F Oven Time Chart
| Tenderloin size | Typical shape | Approx. time at 375°F | When to start checking |
|---|---|---|---|
| 3/4 lb | Small, narrow | 18 to 22 minutes | 16 minutes |
| 1 lb | Standard single tenderloin | 22 to 27 minutes | 20 minutes |
| 1 1/4 lb | Thicker center | 26 to 31 minutes | 24 minutes |
| 1 1/2 lb | Large, plump | 30 to 35 minutes | 28 minutes |
| 2 lb | Often 2 pieces in one pack | 22 to 30 minutes per piece | 20 minutes |
A true pork tenderloin is usually 3/4 to 1 1/2 lb. If the package says 2 lb, it is commonly two separate tenderloins. Cook by the size of each piece, not the total package weight.
Example: if a 2 lb pack contains two 1 lb tenderloins, expect about 22 to 27 minutes, not 40 to 50 minutes. Space them at least 1 inch apart so hot air can reach both sides.
For a 1 lb tenderloin seared first, plan on 20 to 24 minutes at 375°F. Searing gives the outside a head start, so begin checking early.
For a 1 lb tenderloin placed in the oven without searing, plan on 24 to 27 minutes. A cold pan can add 2 to 4 minutes compared with a preheated sheet pan or skillet.
Thickness Adjustments
Weight is not perfect because tenderloins vary in shape. A long, thin 1 lb tenderloin may finish in 21 to 23 minutes. A short, thick 1 lb tenderloin may need 26 to 28 minutes.
If the thickest part is under 2 inches across, check 3 to 5 minutes earlier than the chart. If it is over 2 1/2 inches across, expect the high end of the range.
Tucking the narrow tail under helps the thin end avoid overcooking. Tie it with kitchen twine or fold it under the roast before placing it on the pan.
Worked Timing Examples
Example 1: a 3/4 lb tenderloin, no sear, on a rimmed sheet pan. Start checking at 16 minutes. It will often land at 145°F around 19 to 21 minutes.
Example 2: a 1 1/4 lb tenderloin, seared in an oven-safe skillet. Roast at 375°F and check at 24 minutes. Most finish between 26 and 29 minutes.
Example 3: two 1 1/2 lb tenderloins on one pan. Start checking at 28 minutes. If they are close together, rotate the pan and expect 32 to 37 minutes.
Do not use color as the final test. Pork tenderloin can be slightly pink at 145°F. Use an instant-read thermometer in the thickest center, then rest for 3 minutes before slicing.
If stuffing, wrapping, or heavy sauce is involved, timing becomes less predictable. Check the center of the pork and the thickest stuffed or covered area before serving.
How To Bake It
Bake pork tenderloin at 375°F until the thickest center reaches 145°F, then rest it 3 minutes. For most 1 to 1 1/2 lb tenderloins, plan on 22 to 30 minutes in the oven.
Basic 375°F Method
- 1. Heat the oven: Set the oven to 375°F. Use a rimmed sheet pan, shallow roasting pan, or oven-safe skillet. Line with foil only if you want easier cleanup; it does not change doneness.
- 2. Trim and dry: Remove the silver skin if present. Pat the tenderloin dry. A wet surface steams first, which slows browning and can add a few minutes to the cook.
- 3. Season: Use about 1 teaspoon kosher salt per 1 1/2 lb tenderloin, plus pepper, garlic powder, paprika, or herbs. Rub with 1 tablespoon oil so the surface browns evenly.
- 4. Position it correctly: Place the tenderloin straight, not curled. Tuck the thin tail under itself so the narrow end does not overcook before the thick center reaches 145°F.
- 5. Bake at 375°F: Cook uncovered. Start checking at 18 minutes for a small tenderloin, 22 minutes for an average one, and 28 minutes for a large or thick one.
- 6. Check the center: Insert an instant-read thermometer sideways into the thickest part. Pull it from the oven when the center reads 145°F.
- 7. Rest before slicing: Rest the pork 3 minutes. Slice across the grain into 1/2-inch medallions. Spoon any pan juices over the slices.
Timing By Size At 375°F
| Tenderloin Size | Approximate Oven Time | When To Check |
|---|---|---|
| 3/4 lb, slender | 18 to 22 minutes | 18 minutes |
| 1 lb, average | 22 to 25 minutes | 22 minutes |
| 1 1/4 lb | 24 to 28 minutes | 24 minutes |
| 1 1/2 lb, thick | 28 to 32 minutes | 28 minutes |
| Two 1 lb tenderloins | 24 to 28 minutes | 24 minutes |
Two tenderloins do not take twice as long if they are spaced apart. Leave at least 1 inch between them so hot air can circulate. If they touch, treat them like one thicker roast and check later.
Worked example: a 1.1 lb tenderloin, straightened on a sheet pan, usually lands near 24 minutes. Check at 22 minutes. If it reads 138°F, return it for 3 to 5 minutes, then check again.
Another example: a 1 1/2 lb tenderloin with a thick center may need 30 minutes. If the ends are done-looking but the center is 140°F, cover the ends loosely with foil and bake 3 to 4 minutes more.
For Better Browning
For a darker crust, sear first in an oven-safe skillet over medium-high heat for 2 minutes per side, then bake at 375°F. Start checking after 14 to 16 oven minutes because the sear gives it a head start.
If you skip searing, bake the full time and finish with pan juices, glaze, or a 2-minute broil only after the center has reached 145°F. Watch closely; sugar-based glazes can darken fast.
Do not judge pork tenderloin by color alone. A properly cooked center can still be slightly pink. The deciding number is 145°F in the thickest part, followed by a 3-minute rest.
When To Check Doneness
At 375°F, start checking pork tenderloin before the recipe’s estimated finish time. The target is 145°F in the thickest part, followed by a 3-minute rest.
For most pork tenderloins, the first temperature check should happen at 18 minutes. Very small pieces can finish sooner, while thick or stuffed-looking tied roasts need more time.
First Check Times At 375°F
| Tenderloin size | First check | Likely finish range |
|---|---|---|
| 12 oz, narrow | 15 minutes | 16 to 20 minutes |
| 1 lb, average | 18 minutes | 20 to 25 minutes |
| 1 1/4 lb, thick center | 20 minutes | 24 to 30 minutes |
| 1 1/2 lb, very thick | 22 minutes | 28 to 35 minutes |
| Two tenderloins on one pan | 20 minutes | 25 to 35 minutes |
Use an instant-read thermometer. Insert it from the side into the center of the thickest section, not from the top into a thin edge. Avoid touching the sheet pan, rack, or a fat seam.
If the reading is 135°F to 139°F, keep roasting and check again in 4 minutes. If it reads 140°F to 144°F, check again in 2 minutes.
If it reads 145°F or higher in the thickest part, remove it from the oven. Rest it for 3 minutes before slicing, because pork tenderloin is covered by the 145°F plus 3-minute rest rule.
Worked Examples
Example 1: A 1 lb tenderloin goes into a 375°F oven. Check at 18 minutes. If it reads 138°F, roast 4 more minutes and check again. It will often land near 145°F at 22 to 24 minutes.
Example 2: A 1 1/4 lb tenderloin has a thick middle and tapered ends. Check at 20 minutes. If the center is 142°F, roast 2 more minutes, then recheck the same center spot.
Example 3: Two 1 lb tenderloins on one sheet pan should not touch. Check both at 20 minutes. If one is 145°F and the other is 140°F, remove the done one and continue the other.
Edge Cases That Change The Check Time
- Searing first: If you seared the tenderloin in a skillet before roasting, start checking 3 to 5 minutes earlier than the table.
- Cold from the fridge: If it went straight from refrigerator to oven, use the table as written. Do not delay the first check just because the meat felt cold.
- Very tapered tenderloin: The thin tail may look done early. Judge doneness by the thickest center, not the small end.
- Glazed or sugar-coated: Browning can look finished before the center is done. Start checking by thermometer at the listed first-check time.
- Foil-covered roasting: Covered meat may cook more gently. Check on schedule, then continue in 3-minute intervals if below 145°F.
Do not rely on color alone. Pork tenderloin can be slightly pink at 145°F after the 3-minute rest, and an overcooked tenderloin can still show a pale center.
Resting Before Slicing
Rest pork tenderloin for 3 minutes minimum after it reaches 145°F in the thickest part. That 3-minute rest is part of the USDA safe doneness standard for pork roasts, chops, and whole cuts.
For best slicing, rest it 5 to 10 minutes. The first 3 minutes satisfy the safety rest; the extra 2 to 7 minutes help juices settle so the tenderloin does not spill liquid across the cutting board.
Exact timing after a 375°F oven
At 375°F, pull the pork tenderloin when the thermometer reads 145°F. Set it on a clean board or platter, then start a timer immediately. Do not slice before 3 full minutes have passed.
| Tenderloin situation | Rest before slicing | Why |
|---|---|---|
| Small tenderloin, about 1 lb | 5 minutes | Enough time to meet the 3-minute safety rest and reduce juice loss. |
| Average tenderloin, about 1 1/4 to 1 1/2 lb | 7 minutes | Gives the center time to stabilize before cutting into medallions. |
| Large tenderloin, about 2 lb | 10 minutes | Thicker meat benefits from a longer pause before slicing. |
| Two tenderloins on one pan | 5 to 10 minutes each | Rest each piece based on its own thickness and thermometer reading. |
Worked examples
Example 1: a 1 1/4 lb tenderloin comes out of the oven at 6:20 and reads 145°F. The earliest safe slicing time is 6:23. A better serving time is about 6:27.
Example 2: a 2 lb tenderloin reaches 145°F at 7:05. Rest it until at least 7:08. For cleaner slices, wait until 7:15, then cut across the grain.
Example 3: one end reads 145°F, but the center reads lower. Do not start the rest yet. Return it to the 375°F oven until the thickest center reaches 145°F, then rest 3 minutes.
How to rest it correctly
Move the tenderloin off the hot pan. A hot sheet pan keeps cooking the underside faster than the top and can make the bottom edge firmer than the center.
Tent loosely with foil if the kitchen is cool or the side dishes are not ready. Keep the foil arched, not tight. A tight wrap traps steam and can soften the browned surface.
Use the rest time to finish the pan sauce, toss salad, or plate sides. If you slice immediately, a 1 1/2 lb tenderloin can lose several tablespoons of juice in the first minute.
Slice after resting into 1/2-inch medallions for dinner portions. For sandwiches or salads, slice closer to 1/4 inch. Always cut across the grain for the least chewy bite.
If the tenderloin was stuffed, use the poultry-style standard only when applicable to the filling and recipe: 165°F for stuffed meat or casseroles containing meat or poultry. Do not rely on resting to fix an under-temp center.
Frequently Asked Questions
How long do you cook pork tenderloin in the oven at 375°F?
Cook a 1-pound pork tenderloin at 375°F for about 25 to 30 minutes. Start checking early with a meat thermometer. It is done when the thickest part reaches 145°F, then rest it for 3 minutes before slicing.
How long does a 2-pound pork tenderloin take at 375°F?
A 2-pound pork tenderloin usually takes about 35 to 45 minutes at 375°F, depending on thickness. Use the time as a guide only. Pull it from the oven when the center reaches 145°F and let it rest 3 minutes.
Should I cover pork tenderloin with foil when baking at 375°F?
Bake pork tenderloin uncovered at 375°F if you want better browning. If the outside is getting too dark before the center reaches 145°F, loosely tent it with foil near the end. Rest for 3 minutes after cooking.
How do I keep pork tenderloin juicy at 375°F?
Do not overcook it. Check the thickest part with a thermometer after about 22 minutes for a 1-pound tenderloin. Remove it when it reaches 145°F, then rest it for 3 minutes so the juices settle before slicing.
Can I cook pork tenderloin from frozen at 375°F?
Yes, but it will take longer than thawed pork tenderloin. Expect roughly 45 to 60 minutes at 375°F for a typical frozen tenderloin. Use a thermometer and cook until the center reaches 145°F, then rest for 3 minutes.
