Slow cooking a turkey in the oven at a low temperature is the secret to exceptionally juicy meat and crisp, golden skin without the stress of a traditional high-heat roast. By roasting at 275°F (135°C), the turkey cooks gently and evenly, giving you a forgiving window of time and a succulent bird that stays moist even the next day. This method works beautifully for both whole turkeys and bone-in turkey breast, and it frees up your oven for side dishes.
Ingredients
- 1 whole turkey (12–14 lb / 5.4–6.4 kg), thawed if frozen
- 2 tablespoons (30 ml) olive oil or melted butter
- 1 tablespoon (15 g) kosher salt (or 2 teaspoons fine table salt)
- 1 teaspoon (2 g) freshly ground black pepper
- 1 teaspoon (2 g) dried thyme (or 1 tablespoon fresh thyme leaves)
- 1 teaspoon (2 g) dried rosemary (or 1 tablespoon fresh rosemary, chopped)
- 1 teaspoon (2 g) garlic powder
- 1 large onion, quartered
- 2 celery stalks, cut into 3-inch pieces
- 2 carrots, peeled and cut into 3-inch pieces
- 1 lemon, halved (optional)
- 4 cups (946 ml) low-sodium chicken or turkey broth, for the pan
Instructions
- Prep the turkey: Remove the turkey from the refrigerator 1 hour before roasting to take the chill off. Remove the giblets and neck from the cavities (reserve for gravy if desired). Pat the turkey completely dry with paper towels—this is key for crispy skin.
- Season: In a small bowl, mix the salt, pepper, thyme, rosemary, and garlic powder. Rub the turkey all over with the olive oil, then sprinkle the seasoning mixture evenly over the entire surface, including under the skin where possible. Gently loosen the skin over the breast and thighs and rub some seasoning directly on the meat.
- Stuff the cavity: Place the onion, celery, carrots, and lemon (if using) inside the cavity. Do not pack too tightly—you want air to circulate. Tuck the wing tips under the bird and tie the legs together with kitchen twine.
- Preheat and prepare the pan: Preheat your oven to 275°F (135°C). Place the turkey breast-side up on a rack in a large roasting pan. Pour the broth into the bottom of the pan (not over the bird). This will create steam and keep the pan from scorching.
- Roast low and slow: Insert an oven-safe meat thermometer into the thickest part of the thigh without touching the bone. Place the turkey in the oven and roast for about 20 minutes per pound (45 minutes per kg). A 12–14 lb turkey will take approximately 4 to 4.5 hours. If the skin starts to get too dark, tent loosely with aluminum foil.
- Check temperature: The turkey is done when the thermometer reads 165°F (74°C) in the thigh and the juices run clear. This is the USDA FSIS safe minimum internal temperature for poultry. Start checking at the 4-hour mark.
- Rest: Carefully remove the turkey from the oven. Transfer it to a cutting board and let it rest, uncovered, for 30–45 minutes. This allows the juices to redistribute—do not skip this step.
- Carve and serve: Carve the turkey and serve with the pan juices (skim off fat) or use them to make gravy.
Tips
- Don’t peek: Every time you open the oven, heat escapes and adds cooking time. Use the oven light and window to check progress.
- Use a thermometer: Rely on temperature, not time. A digital instant-read thermometer is your best friend. Insert it into the thickest part of the thigh, avoiding the bone.
- No rack? Use vegetables: If you don’t have a roasting rack, lay thick slices of onion and celery on the bottom of the pan and place the turkey on top. This keeps it out of the drippings and adds flavor.
- Brine for extra moisture: For an even juicier bird, dry-brine the turkey 24 hours ahead: rub salt all over and refrigerate uncovered. Rinse and pat dry before roasting.
Serving Suggestions
Serve the slow-cooked turkey with classic sides like mashed potatoes, green bean casserole, cranberry sauce, and dinner rolls. The pan drippings make an excellent base for a rich gravy. For a lighter meal, slice the turkey and serve over a salad or in sandwiches with leftover cranberry sauce.
Variations
- Herb butter: Instead of olive oil, mix 1/2 cup (113 g) softened butter with 2 tablespoons chopped fresh sage, 1 tablespoon thyme, and 1 teaspoon lemon zest. Rub under the skin for extra richness.
- Spice rub: Add 1 tablespoon smoked paprika, 1 teaspoon cayenne, and 1 teaspoon cumin to the seasoning mix for a smoky, spicy crust.
- Citrus and herb: Stuff the cavity with orange slices, fresh sage, and bay leaves instead of lemon for a brighter flavor.
- Bone-in breast only: For a smaller gathering, use a 6–8 lb (2.7–3.6 kg) bone-in turkey breast and reduce the cooking time to about 3 hours, or until it reaches 165°F (74°C).
Storage and Reheating
Refrigerate leftover turkey within 2 hours of cooking. Carve the meat off the bones and store in an airtight container for up to 4 days. For longer storage, wrap tightly and freeze for up to 3 months. To reheat, place slices in a baking dish with a little broth, cover with foil, and warm in a 325°F (163°C) oven for 15–20 minutes, or until heated through to 165°F (74°C). You can also microwave individual portions in 30-second bursts.
Frequently Asked Questions
Is it safe to cook a turkey at 275°F? Yes, 275°F (135°C) is safe as long as the turkey reaches 165°F (74°C) in the thigh. The lower temperature just takes longer. Always use a thermometer to confirm doneness.
How long does it take to slow cook a turkey? Plan on about 20 minutes per pound (45 minutes per kg) at 275°F (135°C). A 12 lb turkey takes about 4 hours, a 14 lb about 4.5 hours. Always rely on the thermometer, not just the clock.
Can I stuff the turkey? Yes, but it’s safer to cook stuffing separately. If you stuff the bird, the stuffing must also reach 165°F (74°C), which often means overcooking the meat. For food safety, we recommend cooking stuffing in a casserole dish.
Why is my turkey skin not crispy? Low heat doesn’t crisp skin as well as high heat. To fix, after the turkey is done, increase the oven to 450°F (232°C) and roast for 10–15 minutes, watching closely. Or, pat the skin very dry before roasting and don’t baste with juices (basting makes skin soggy).
Can I use a frozen turkey? No, always thaw completely in the refrigerator (24 hours per 4–5 lb). Cooking from frozen will result in uneven cooking and unsafe temperatures. Plan ahead.
What if my turkey is done early? If it reaches 165°F (74°C) before your meal time, let it rest on the counter for 30 minutes, then carve and keep warm in a low oven (200°F/93°C) covered with foil for up to an hour.
