A four-pound turkey breast usually takes about 1 hour 50 minutes to roast at 350°F (177°C), but the thermometer—not the clock—determines when it is done. This simple oven-roasted version seasons a bone-in, skin-on breast with herb butter and aromatics, then rests it before carving into tender slices.
Ingredients
- 1 bone-in, skin-on turkey breast, about 4 pounds (1.8 kg), fully thawed
- 3 tablespoons (42 g) unsalted butter, softened
- 1 tablespoon (15 ml) olive oil
- 1 teaspoon (6 g) fine kosher salt
- ½ teaspoon (1 g) freshly ground black pepper
- 1 teaspoon (2 g) paprika
- 4 garlic cloves (12 g), finely grated or minced
- 4 fresh thyme sprigs (about 4 g), leaves picked and chopped; or 1 teaspoon (1 g) dried thyme
- 1 medium yellow onion (about 150 g), cut into thick wedges
- ½ lemon (about 30 g), cut into wedges
- 1 cup (240 ml) low-sodium chicken or turkey broth
Instructions
- Thaw and prepare the breast. If the turkey is frozen, thaw it in its original wrapping on a tray in the refrigerator; a four-pound breast generally needs about 24 hours, though the exact time depends on its shape and your refrigerator. Do not thaw it on the counter. Remove the neck or packet of giblets if included, and pat the breast dry all over with paper towels. Dry skin browns more readily than damp skin. Let the turkey sit out only while you season it, rather than leaving raw poultry at room temperature for an extended period.
- Heat the oven and make the herb butter. Set a rack in the center of the oven and preheat to 350°F (177°C). In a small bowl, mix the softened butter, olive oil, salt, pepper, paprika, garlic, and chopped thyme. The oil makes the butter easier to spread, while the paprika gives the skin color; it is for flavor and appearance, not a doneness indicator.
- Season the turkey. Gently loosen the skin over the breast meat with your fingers, taking care not to tear it. Spread about half of the butter mixture directly over the meat beneath the skin. Rub the remainder over the outside of the skin. This distributes seasoning where it can flavor the breast and helps the surface brown. If the skin will not loosen easily, simply rub the butter mixture over the outside; do not force it.
- Arrange the roasting pan. Put the onion and lemon wedges in the bottom of a roasting pan or oven-safe baking dish, and set the turkey breast on top, skin side up. If you have a roasting rack, place it over the vegetables first. Pour the broth into the pan around—not over—the turkey. The vegetables lift the meat slightly and add flavor to the pan juices. They are not a substitute for checking the breast with a thermometer.
- Roast until safely cooked. Roast uncovered for about 1 hour 50 minutes as a starting estimate. Begin checking at 1 hour 30 minutes because breast shape, starting temperature, oven calibration, and whether the bone is included can change the timing. If the skin becomes deep golden before the center is done, loosely cover the browned area with foil. The turkey is ready when a food thermometer inserted into the thickest part of the breast, without touching bone, reads 165°F (74°C). This is the USDA FSIS safe minimum internal temperature for poultry. Check more than one spot if the breast is uneven, and return it to the oven if any reading is below 165°F (74°C).
- Rest, then carve. Transfer the cooked breast to a carving board and tent it loosely with foil. Rest for 20 minutes before slicing. Resting gives the hot juices time to settle and makes the meat easier to carve; do not leave it out for more than two hours. Slice across the grain, working from the breastbone outward if the breast is bone-in. Spoon a little of the warm pan juice over the slices, if desired.
Tips
- Use a thermometer in the right place. Insert an instant-read thermometer into the thickest area of meat, approaching from the side if that helps you avoid the bone. A temperature taken against bone can be misleading, and color or clear juices alone cannot confirm that poultry has reached a safe temperature. An oven-safe probe thermometer is useful because it lets you follow the temperature as the breast roasts.
- Start with a fully thawed breast. A partly frozen center cooks unevenly and makes the timing harder to predict. If the package includes a pop-up indicator, treat it as a rough signal only; verify the thickest part with a separate food thermometer. Avoid rinsing raw turkey, since splashing can spread raw poultry juices around the sink and nearby surfaces.
- Adjust for the kind of salt you have. The listed amount is for fine kosher salt. If using a denser table salt, start with about ¾ teaspoon (4 g), since equal spoonfuls can taste saltier. For a salt-free seasoning blend, check the label and season to taste rather than adding the full salt quantity automatically.
- Save the pan juices safely. Strain them into a small saucepan if you want a quick serving sauce, and bring them to a boil before serving. If you do not plan to serve the juices immediately, refrigerate them with the leftover turkey within two hours. Do not use raw-turkey packaging liquid or uncooked marinade as a sauce unless it is thoroughly cooked.
Serving Suggestions
Serve the sliced turkey while it is warm, with the roasted onion and lemon from the pan and a spoonful of the cooking juices. Mashed potatoes, roasted carrots, green beans, or a crisp salad make straightforward sides; dinner rolls or cornbread are helpful for soaking up the juices. For a holiday-style plate, add stuffing, cranberry sauce, and a vegetable side, keeping hot foods hot until serving.
A four-pound breast typically gives about six portions, though the yield depends on the size of the bone and how generously you slice. If you are serving a larger group, plan another main dish or increase the number of turkey breasts rather than assuming a single breast will stretch to many large servings. Carve only what you expect to serve at first; keeping the remaining breast in larger pieces helps it stay moist while it waits for later servings.
Variations
Use rosemary or sage. Replace the thyme with 1 tablespoon (about 3 g) chopped fresh rosemary or sage, or use 1 teaspoon (1 g) dried herbs. Rosemary has a stronger, pine-like flavor, while sage is earthy and especially suited to classic holiday sides. If using dried herbs, crush them between your fingers before mixing them into the butter to release their aroma.
Add citrus and warm spices. Swap the lemon for orange wedges and replace the paprika with ½ teaspoon (1 g) ground cumin or a pinch of ground coriander. These additions give the pan juices a brighter, gently spiced flavor without changing the roasting method. Keep the quantities modest so they complement rather than hide the turkey.
Make it dairy-free. Replace the butter with 3 tablespoons (45 ml) olive oil. The meat will still take the same time to cook, but the skin may brown a little differently and will not have the buttery flavor. For a boneless breast, use the same seasonings but expect the cooking time to be shorter and less predictable; check the thickest center early and cook to 165°F (74°C), rather than relying on the bone-in timing.
Change the aromatics. Carrot and celery pieces can replace some or all of the onion in the pan. They contribute a savory base to the juices, though they will be soft after roasting. If you do not have broth, use water; the pan juices will be a little less rich, but the turkey will still roast properly. Do not pour liquid over the skin, since that can interfere with browning.
Storage and Reheating
Refrigerate cooked turkey within two hours of cooking, sooner if the room is very warm. Remove the meat from the bone if convenient, then store it in a shallow, airtight container with a spoonful of pan juices to help limit drying. Refrigerated cooked turkey keeps for 3–4 days. Keep the refrigerator at 40°F (4°C) or colder, and store the turkey separately from raw meat or poultry.
For longer storage, freeze sliced or portioned turkey in a freezer-safe, airtight container. It is best used within about 2–3 months for quality; thaw it in the refrigerator rather than on the counter. Reheat only the amount you plan to eat. Warm slices covered in a baking dish with a splash of broth in a 325°F (163°C) oven, or heat them gently in a covered skillet with a little liquid. Microwave portions covered, turning or rearranging them partway through. In every case, leftovers should reach 165°F (74°C), the USDA FSIS safe temperature for reheated leftovers.
Frequently Asked Questions
How long does a four-pound turkey breast take at 350°F?
For a bone-in breast, plan on roughly 1 hour 50 minutes, with a practical range of about 1 hour 30 minutes to 2 hours 15 minutes. Oven accuracy, the breast’s shape, and how cold it is when it goes into the oven all affect the time. Start checking early and use 165°F (74°C) in the thickest part as the finish line.
Does a four-pound turkey breast cook faster than a whole turkey?
Usually, yes. A breast is a smaller, less bulky roast than a whole turkey, so it generally needs less oven time. Still, do not calculate doneness by multiplying a per-pound rule or copying the timing for a whole bird. The breast’s shape and whether it is bone-in matter, and a thermometer gives the reliable answer.
Should I roast the turkey breast covered or uncovered?
Roast it uncovered so the skin can brown. If the skin gets as dark as you want before the meat reaches 165°F (74°C), loosely shield it with foil and continue cooking. Covering the pan from the start traps steam and tends to make the skin softer rather than crisp.
Can I cook a frozen turkey breast without thawing it?
Thawing first is the simplest way to get more even cooking and predictable timing. If you choose to cook a breast from frozen, follow the package directions for that specific product, allow substantially more time, and verify 165°F (74°C) in the thickest part with a food thermometer. Do not use a slow cooker for frozen poultry.
How long should turkey breast rest before carving?
Rest it for 20 minutes, loosely tented with foil. This brief pause also gives you time to finish side dishes or strain the pan juices. Keep the turkey protected from contamination, and refrigerate leftovers within two hours of cooking.
Can I use this timing for a boneless turkey breast?
Not exactly. A boneless breast is often more compact and may finish sooner, while tied or rolled products can vary in thickness. Use the same 350°F (177°C) oven temperature if appropriate for the package, begin checking earlier than you would for a bone-in breast, and cook until the center reaches 165°F (74°C). The thermometer reading matters more than the estimated minutes.
