A boneless turkey breast roast cooks in a 350°F (177°C) oven for about 1 hour 15 minutes when it weighs around 2½ pounds (1.1 kg), followed by a 15-minute rest. The dependable cue is its temperature, not the clock: use a food thermometer and cook the thickest part to 165°F (74°C) for moist, safely cooked slices.
Ingredients
- 1 boneless turkey breast roast, about 2½ lb (1.1 kg), thawed and tied or held in oven-safe netting
- 1 tbsp (15 ml) olive oil
- 2 tbsp (28 g) unsalted butter, softened
- 1½ tsp (about 4 g) kosher salt
- 1 tsp (2 g) freshly ground black pepper
- 1 tsp (3 g) garlic powder
- 1 tsp (1 g) dried thyme
- ½ cup (120 ml) low-sodium chicken or turkey broth
Instructions
- Thaw and prepare the roast. If frozen, thaw the turkey breast in the refrigerator before cooking; a roast of this size commonly needs about 24 hours, though a thicker one can take longer. Remove the wrapper and any absorbent pad, then pat the meat dry with paper towels. Do not rinse raw poultry. Check the package to see whether its netting is oven-safe: leave it on for roasting only if the label says it can stay on, and remove it after resting. If there is no netting, secure the roast with kitchen twine so it cooks in an even shape.
- Heat the oven and prepare the pan. Set a rack in the middle of the oven and preheat to 350°F (177°C). Pour the broth into a small roasting pan or baking dish, then set a roasting rack inside if you have one. The rack helps hot air circulate; if you do not have one, the roast can sit directly in the pan. The broth provides a little moisture in the pan and helps keep any drippings from scorching.
- Season the turkey. Stir together the softened butter, olive oil, salt, pepper, garlic powder, and dried thyme. Rub the mixture over all sides of the roast, working it into any folds. Place the roast seam-side down in the pan. If the roast came pre-seasoned or injected with a solution, check its label and reduce or omit the added salt to avoid an overly salty result.
- Roast until safely cooked. Put the pan in the oven and roast for about 1 hour 15 minutes. For this size, begin checking at about 1 hour; the shape and thickness of the roast, your oven, and whether it started very cold can change the timing. Insert an instant-read food thermometer into the thickest part, aiming for the center and avoiding the pan or any pocket of fat. The USDA FSIS safe minimum internal temperature for poultry is 165°F (74°C); cook to that reading before removing the roast. If it has not reached 165°F (74°C), return it to the oven and check again every 10 minutes.
- Rest before slicing. Transfer the roast to a cutting board and loosely tent it with foil. Rest for 15 minutes so the juices settle and the meat is easier to slice. The temperature must already have reached 165°F (74°C) before resting; do not rely on carryover cooking to bring an under-temperature roast to the safe minimum.
- Slice and serve. Remove any netting or twine. Slice across the grain into pieces about ¼ inch (6 mm) thick, using a sharp knife. Spoon a little pan liquid over the slices if desired. If you want to serve pan juices, pour them into a small dish and skim excess fat from the surface.
Tips
- Use temperature as the final test. A cooking-time estimate helps you plan dinner, but a thermometer is what tells you the roast is ready. Check the center of the thickest area in more than one spot if the roast is irregularly shaped.
- Choose a thermometer that fits the job. An instant-read thermometer is useful for checking near the end. If using an oven-safe probe, place it in the center before roasting and still verify the reading in another spot when the roast is done.
- Watch the salt in packaged roasts. Some boneless turkey breasts are brined or seasoned before sale. Read the label; if it lists added salt or a salt solution, use less salt in the butter mixture or leave it out.
- Do not skip the rest. Slicing immediately can spill juices onto the board and make the meat seem drier. Keep the foil loose rather than wrapping tightly, which can soften the browned exterior.
Serving Suggestions
Serve the sliced turkey as the centerpiece of a simple dinner with mashed potatoes, roasted carrots, green beans, or a crisp salad. The mild herb-and-garlic seasoning also works with rice pilaf, stuffing, baked sweet potatoes, and cranberry sauce. For a holiday-style plate, arrange the slices in overlapping rows on a warmed platter and add a small bowl of pan juices or gravy alongside rather than pouring it over the whole roast.
Leftover slices are useful beyond the first meal. Add them to sandwiches with mustard and lettuce, tuck them into a wrap with greens, or serve them cold with crackers and sliced vegetables. For a warm lunch, place turkey on top of a bowl of rice or cooked grains and add vegetables and a spoonful of broth or gravy to keep the meat from drying out.
Variations
Lemon and rosemary: Replace the thyme with 1 tsp (1 g) finely chopped fresh rosemary and add 1 tsp (5 ml) lemon zest to the butter mixture. Rosemary has a more resinous, pronounced flavor than thyme, so keep the amount modest. A squeeze of lemon over the sliced turkey brightens the finished plate.
Smoky paprika: Add 1 tsp (2 g) smoked paprika to the seasoning and use the same cooking temperature. It gives the outside a warm, smoky flavor and a deeper color without requiring a smoker. Paprika can darken before the center is done, so judge doneness by temperature rather than browning.
Mustard-herb coating: Replace the olive oil with 1 tbsp (15 g) Dijon mustard and mix it into the softened butter with the herbs. The mustard adds a tangy, savory note and helps the seasoning cling to the surface. Choose a lower-salt mustard if the packaged roast is already seasoned.
Use fresh herbs: Swap the dried thyme for 1 tbsp (3 g) chopped fresh thyme. Fresh herbs are less concentrated by volume, so a teaspoon-for-teaspoon exchange will taste less herbal. You can also use a combination of fresh parsley and thyme, while keeping the same salt and temperature guidance.
Storage and Reheating
Refrigerate cooked turkey within 2 hours of cooking, dividing a large amount into shallow containers so it cools promptly. Store it covered in the refrigerator for 3 to 4 days. For longer storage, freeze sliced or portioned turkey in airtight freezer-safe packaging; for best texture, use it within about 2 to 3 months. Thaw frozen leftovers in the refrigerator, not on the counter.
Reheat only the amount you plan to eat. Add a splash of broth or water, cover the dish, and warm the turkey in a 300°F (149°C) oven until hot, or microwave it in short intervals with a cover. Stir or rearrange pieces as needed for even heating. USDA FSIS recommends reheating leftovers to 165°F (74°C), checked with a food thermometer. Thin slices heat quickly, so check them before they become dry.
Frequently Asked Questions
How many minutes per pound does a boneless turkey breast roast need?
At 350°F (177°C), a useful planning estimate is about 25 to 30 minutes per pound, but the shape and thickness of the roast matter more than weight alone. A 2½-pound roast often takes around 1 hour 15 minutes, while a compact or especially thick roast may take longer. Start checking early and cook to 165°F (74°C) at the center.
Should I cover the turkey breast while it roasts?
Usually, no. Roasting uncovered lets the surface brown. If the outside is getting very dark before the center reaches 165°F (74°C), loosely cover the top with foil and continue cooking. Avoid sealing the pan tightly from the start, since that traps steam and can leave the exterior pale.
Can I cook a boneless turkey breast roast from frozen?
For this recipe, thawing in the refrigerator first gives more even seasoning and makes the time estimate more useful. USDA guidance allows poultry to be oven-cooked from frozen, but it can take at least 50 percent longer, and this recipe’s timing will not apply. Follow the product instructions, check the thickest area and any separate sections with a thermometer, and make sure all the turkey reaches 165°F (74°C).
Do I leave the netting on the turkey breast?
Check the package directions. If the netting is labeled oven-safe, leave it in place during roasting to help the boneless roast hold its shape, then cut it away after the 15-minute rest. If it is not labeled oven-safe or the package says to remove it, take it off and tie the roast with kitchen twine before cooking.
Why is my turkey breast roast dry?
The most common cause is cooking past the safe temperature, especially when the roast is small or thin. Check it early with a thermometer rather than waiting for a fixed time, and let it rest before slicing. Cutting thinly across the grain and serving with pan juices or gravy can also make the slices more pleasant to eat.
Can I roast two turkey breasts at once?
Yes, if they fit in the pan with space around them for air to circulate. Two roasts do not necessarily take twice as long, but a crowded pan or larger total load may slow cooking. Check each roast separately, since one may be done before the other, and remove each only when its thickest part reaches 165°F (74°C).
