How Long to Cook Turkey Breast Roast in the Oven at 350°F

A turkey breast roast is a boneless or bone-in cut seasoned and roasted until tender, then sliced for a simple main dish. For a 3-pound boneless roast, plan on about 1 hour 20 minutes to 1 hour 45 minutes at 350°F (177°C), but use a thermometer—not the clock—to decide when it is done.

Ingredients

  • 1 boneless, skin-on turkey breast roast, about 3 lb (1.36 kg), thawed; keep any butcher’s or oven-safe netting in place during roasting unless the package says otherwise
  • 1 tbsp (15 ml) olive oil
  • 1½ tsp (9 g) kosher salt, or 1 tsp (6 g) fine table salt
  • ½ tsp (1 g) freshly ground black pepper
  • 1 tsp (3 g) garlic powder
  • 1 tsp (1 g) dried thyme
  • ½ tsp (1 g) paprika
  • ½ cup (120 ml) low-sodium chicken or turkey broth, for the roasting pan

Instructions

  1. Thaw and prepare the roast. If frozen, thaw the turkey in its unopened packaging on a tray in the refrigerator; allow roughly 24 hours for every 4 to 5 lb (1.8 to 2.3 kg), so a 3-pound roast may need about a day. Do not thaw poultry on the counter. Take the thawed roast from the refrigerator while the oven heats, remove its outer wrapping, and pat the surface dry with paper towels. Do not rinse raw turkey, since splashing can spread raw poultry juices around the sink.
  2. Heat the oven and season. Set a rack in the center of the oven and preheat to 350°F (177°C). Stir the salt, pepper, garlic powder, thyme, and paprika together in a small bowl. Rub the turkey all over with the oil, then press the seasoning mixture onto the surface. If the skin is tucked under netting, season the accessible surface; do not cut the netting off before roasting unless the product directions specifically call for it.
  3. Set up the roasting pan. Place the roast skin-side up on a rack in a shallow roasting pan. Pour the broth into the bottom of the pan, keeping it below the rack so it does not wash seasoning off the turkey. If you do not have a rack, set the roast on a bed of thick onion slices in a roasting dish; they lift it slightly and add flavor to the pan juices. The broth is there to catch drippings and reduce scorching, not to submerge or poach the meat.
  4. Roast until it reaches a safe temperature. Roast uncovered, allowing about 1 hour 20 minutes to 1 hour 45 minutes for a 3-pound boneless roast. Begin checking near the early end of the estimate because shape, starting temperature, oven accuracy, and whether the roast is tied all affect the timing. Insert an instant-read thermometer into the thickest part of the meat, avoiding the pan and any bone; the USDA FSIS safe minimum internal temperature for poultry is 165°F (74°C), checked with a food thermometer. If the surface gets dark before the center is ready, tent it loosely with foil and continue roasting.
  5. Rest, then slice. Transfer the cooked roast to a cutting board and rest it for 15 minutes before carving. Resting makes it easier to slice neatly and gives the juices time to settle; it does not replace the requirement to reach 165°F (74°C) during cooking. Remove any netting after the rest, if present, and slice across the grain into pieces about ¼ to ½ inch (6 to 12 mm) thick. Spoon a little of the pan juice over the slices, after checking it is hot, and serve.

How to Estimate the Cooking Time

Cooking time depends on the roast’s weight and shape, whether it is boneless or bone-in, how cold it was when it went into the oven, and how your oven heats. For this recipe, a 3-pound boneless roast at 350°F (177°C) typically takes around 1 hour 20 minutes to 1 hour 45 minutes. A smaller roast may finish sooner, while a thick, compact roast may take longer even if its weight is similar. Treat these times as a planning range rather than a guarantee.

For a rough guide, allow about 25 to 35 minutes per pound for a boneless roast at 350°F (177°C), then start checking the temperature before the low end of that estimate. Bone-in turkey breasts are often larger and can take roughly 1¾ to 2½ hours for a 4- to 6-pound piece, but the exact time varies substantially. If the package gives a method or timing for that particular roast, read it as well. The thermometer reading in the thickest section is the reliable doneness check for either type.

Tips

  • Check the label before salting. Some turkey roasts are already injected, brined, or seasoned. If yours is labeled pre-brined or contains added salt, reduce the added kosher salt to ½ teaspoon (3 g), or omit it and season to taste after cooking.
  • Use an oven thermometer if timing seems off. An oven set to 350°F (177°C) may run hotter or cooler than its display suggests. A separate oven thermometer can help explain why a roast is browning unusually fast or taking longer than expected.
  • Keep the thermometer in the meat’s thickest area. Check more than one spot if the roast has an uneven shape, and avoid touching bone or the roasting pan. If one section is below 165°F (74°C), return the roast to the oven and check again after a short interval.
  • Let the roast rest before carving. Cutting immediately can make the slices harder to manage and let more juice run onto the board. If you need to hold it longer than 15 minutes, tent it loosely with foil; a tight covering traps steam and softens crisp skin.

Serving Suggestions

Serve sliced turkey with mashed or roasted potatoes, green beans, glazed carrots, roasted Brussels sprouts, or a crisp salad. A tart cranberry sauce or a spoonful of chutney provides a bright contrast to the mild meat, while gravy made from the pan drippings makes the plate more substantial. For gravy, pour the drippings into a measuring cup, skim off excess fat, and use the liquid as part of your usual gravy recipe; the small amount of broth in the pan may not make enough gravy on its own.

This roast also works well for a smaller holiday meal or a weeknight dinner when a whole turkey would be too much. Arrange the slices on a warm platter shortly before serving and spoon over only a little juice, leaving extra at the table so the surface does not become soggy. If you are serving guests, slice only what you expect to eat first and keep the remaining roast intact until needed; a larger piece stays easier to reheat without drying out.

Variations

Lemon and herbs: Add 1 teaspoon (2 g) finely grated lemon zest to the seasoning and use rosemary instead of thyme. The citrus gives the turkey a fresher aroma without changing the basic roasting method. For a more pronounced lemon flavor, serve wedges alongside rather than adding a large amount of juice to the raw surface.

Smoky seasoning: Replace the paprika with smoked paprika and add ½ teaspoon (1 g) ground cumin. This gives the roast a warm, smoky note that pairs nicely with roasted vegetables or corn. Keep the salt level the same unless the turkey is already seasoned.

Butter and fresh herbs: Use 1 tablespoon (14 g) softened butter in place of the olive oil, and mix the thyme with 1 tablespoon (3 g) chopped parsley or sage. Butter can help the surface brown, so tent the roast loosely with foil if it darkens well before the center reaches its safe temperature.

Bone-in turkey breast: The seasoning mixture can be used on a bone-in breast, but choose one that fits your roasting pan and expect a different cooking time. Roast at the same oven temperature, begin checking early, and place the thermometer in the thickest part without touching the bone. A bone-in roast is not ready merely because the outside looks browned.

Storage and Reheating

Refrigerate cooked turkey within 2 hours of cooking, dividing a large amount into shallow containers so it cools promptly. Store slices or leftover roast in a covered airtight container in the refrigerator for 3 to 4 days. Keep gravy and other pan juices in a separate container if possible. For longer storage, freeze the turkey in airtight freezer-safe packaging; for best quality, use it within about 2 to 3 months, and thaw it in the refrigerator before reheating.

To reheat slices, place them in a covered oven-safe dish with a spoonful or two of broth or gravy and warm at 325°F (163°C) until hot throughout. You can also microwave a portion in a covered microwave-safe dish, turning or rearranging the pieces for even heating. Reheat leftovers to 165°F (74°C), checked with a food thermometer. Heat only the portion you plan to serve, since repeated warming and cooling can reduce quality.

Frequently Asked Questions

How long does a 3-pound turkey breast roast take at 350°F?
A 3-pound boneless roast usually takes about 1 hour 20 minutes to 1 hour 45 minutes at 350°F (177°C). Start checking before the lower end of that range, since the roast’s shape and your oven affect the timing. It is done when the thickest part reaches 165°F (74°C), not simply when the timer ends.

Should I cover a turkey breast roast while it cooks?
Roast it uncovered to help the outside brown. If it is browning too quickly while the center is still below 165°F (74°C), lay foil loosely over the top and continue cooking. Avoid sealing the pan tightly, which traps steam and can prevent the surface from browning.

Do I need to baste the turkey breast?
No. Basting is optional and does not make the center cook faster; opening the oven repeatedly can also slow cooking. The oil and seasonings provide flavor, while the thermometer determines doneness. If you want to use pan juices, spoon them over the carved meat at the end.

Is a boneless roast quicker than a bone-in turkey breast?
Not always. Boneless roasts are often smaller, so they may cook faster, but thickness and weight matter more than the label alone. Bone-in pieces can take longer because they are usually larger, and the thermometer must be placed in the thickest meat without touching bone. Use a time range to plan and temperature to confirm.

Can I cook a turkey breast roast from frozen?
For this recipe, thaw it safely in the refrigerator before roasting so the seasoning can be applied evenly and the timing is more predictable. Never thaw raw poultry on the counter. If you must cook from frozen, follow a tested method intended for frozen poultry and expect substantially longer cooking; still verify 165°F (74°C) in the thickest part with a thermometer.

Why is my turkey breast roast dry?
Overcooking is a common cause, so check the center early and remove the roast once it reaches 165°F (74°C). A lean breast can lose moisture quickly if left in the oven while waiting for a particular time estimate. Rest it for 15 minutes before slicing, cut across the grain, and serve with warm pan juices or gravy.
