Oven-roasting turkey breast at 350°F delivers consistent results, but the total time hinges on whether you’re working with bone-in or boneless meat. If you want a straight answer to how long to cook turkey breast in oven at 350, plan on 20 minutes per pound for bone-in and 15 to 18 minutes per pound for boneless.
That said, time is only half the story. The turkey is done when it hits 165°F in the thickest part, not when the clock says so.
Below you’ll find exact times, temps, and a simple method that works every time.
How Long To Cook Turkey Breast In Oven At 350
Use this chart as your starting point. Always verify with a meat thermometer before pulling the pan out.
- Bone-in turkey breast, 3 lbs: 60 to 70 minutes
- Bone-in turkey breast, 5 lbs: 1 hour 40 minutes to 1 hour 50 minutes
- Bone-in turkey breast, 7 lbs: 2 hours 20 minutes to 2 hours 30 minutes
- Boneless turkey breast, 2 lbs: 30 to 36 minutes
- Boneless turkey breast, 3 lbs: 45 to 55 minutes
- Boneless turkey breast, 4 lbs: 60 to 72 minutes
Small breasts cook faster per pound than large ones, so a 2-pound boneless roast may finish closer to 40 minutes total. A 7-pound bone-in breast can run long past 2.5 hours if it’s fridge-cold when it goes in.
Why Bone-In And Boneless Times Differ
Bone conducts heat, so it actually helps the meat cook from the inside out. But bone-in breasts are thicker and heavier, which is why the per-pound time is longer overall.
Boneless breasts are usually rolled or tied into a uniform shape. That even thickness means heat reaches the center faster, so you shave off several minutes per pound.
The trade-off is moisture. Bone-in meat tends to stay juicier because the bone and surrounding connective tissue insulate it a bit.
What If Your Turkey Breast Is Frozen
Do not roast a frozen breast at 350°F and guess at the time. It will dry out on the outside before the middle thaws.
Thaw it in the fridge first. Allow 24 hours for every 4 to 5 pounds. A 5-pound breast needs about a full day.
If you’re short on time, submerge the wrapped breast in cold water and change the water every 30 minutes. This cuts thawing to about 30 minutes per pound.
Step-By-Step Method For A Perfect Turkey Breast
Follow these steps and the timing takes care of itself.
- Preheat your oven to 350°F. Place the rack in the middle position.
- Pat the breast dry with paper towels. Moisture on the skin steams the meat instead of roasting it.
- Rub the skin with oil or softened butter. Season generously with salt, pepper, and any herbs you like.
- Set the breast skin-side up in a roasting pan or on a rimmed baking sheet with a rack.
- If it’s bone-in, add a cup of broth or water to the pan to keep drippings from burning.
- Roast uncovered. Do not cover it, or the skin will never brown.
- Start checking the internal temp about 20 minutes before your estimated finish time.
- Pull the breast when the thickest part reads 165°F.
- Rest it on a cutting board for 15 to 20 minutes before slicing.
Resting is not optional. The juices redistribute during those minutes, and slicing early means a dry plate.
Should You Cover The Turkey Breast With Foil
Only if the skin is browning too fast. Lay a loose tent of foil over the top during the last 20 minutes or so.
Don’t wrap it tight. Trapped steam softens the skin you worked to crisp.
If you want extra insurance against dryness, baste once halfway through with pan juices. More than that and you’re just opening the oven and losing heat.
Using A Meat Thermometer Correctly
Instant-read thermometers are cheap and they solve the whole timing problem. Insert the probe into the thickest part of the breast, away from bone and fat.
If you hit bone, you’ll get a false high reading. Pull the probe out slightly and reinsert.
Check two or three spots. The lowest reading is the one that matters.
Common Mistakes That Ruin Turkey Breast
Most dry turkey comes down to one of these errors.
- Going by time alone instead of temperature
- Roasting straight from the fridge without letting the meat sit out for 20 to 30 minutes
- Cooking at a higher temp to save time, which toughens the outer layer
- Skipping the rest period
- Cutting into the breast to check doneness, which releases juices
The fridge-to-oven chill is a big one. A cold center adds 10 to 15 minutes to your total cook time, and it throws off every estimate you made.
How To Fix An Overcooked Breast
If you overshoot 165°F, don’t panic. Slice the meat and serve it with warm broth, gravy, or pan drippings poured over the top.
You can also chop it into a casserole or soup where moisture surrounds every piece. Slightly overcooked turkey makes fine sandwiches the next day.
How To Fix An Undercooked Breast
Return it to the oven and check every 10 minutes. Cover the top loosely with foil so the skin doesn’t scorch while the center catches up.
Never serve turkey below 165°F. Poultry carries bacteria that only heat can kill.
Timing Tips For Different Pan Types
Your pan changes the cook time more than most people realize.
- Dark metal roasting pan: cooks fastest, browns deeply
- Light metal pan: even cooking, moderate browning
- Glass baking dish: slower heat transfer, add 5 to 10 minutes
- Cast iron skillet: great for small boneless breasts, sears the bottom
A rack inside the pan lifts the breast out of the drippings. That keeps the bottom from getting soggy and helps heat circulate all around.
Convection Oven Adjustment
If your oven has a convection fan, drop the temp to 325°F. The moving air cooks food faster and browns it quicker.
Check the internal temperature about 25 percent earlier than the standard time. A 3-pound boneless breast that would take 50 minutes in a regular oven may finish in 38 minutes on convection.
Final Numbers To Remember
At 350°F, bone-in turkey breast needs roughly 20 minutes per pound. Boneless needs 15 to 18 minutes per pound.
Always cook to 165°F, always rest for 15 to 20 minutes, and always trust your thermometer over the clock. Do those three things and your turkey breast comes out juicy every single time.
