How Long to Cook a Turkey at 275 Degrees

Allow 4½ to 5 hours at 325°F for a thawed, unstuffed 20- to 24-pound turkey rather than planning a full oven roast at 275°F, which is below the USDA’s recommended minimum oven temperature. Low-temperature times in some recipes cover only an initial cooking stage, not the entire cook. These USDA roasting estimates provide a more dependable starting point for planning dinner, but a meat thermometer determines when the turkey is ready.

Thawed, Unstuffed Whole Turkey	Approximate Roasting Time at 325°F
8–12 pounds	2¾–3 hours
12–14 pounds	3–3¾ hours
14–18 pounds	3¾–4¼ hours
18–20 pounds	4¼–4½ hours
20–24 pounds	4½–5 hours

What Low-Temperature Turkey Cooking Times Actually Mean

A first-stage cooking time is not a total cooking time.

That distinction explains why you may encounter a surprisingly short estimate for a large turkey. In one covered, two-stage oven recipe, the oven preheats to 275°F, and a 20-pound turkey spends about 3½ hours in the covered first stage. After the foil comes off, the oven increases to 350°F for browning and finishing, with basting every 30 minutes.

The first-stage estimate does not mean that the turkey is ready to eat. It then moves to the hotter finishing stage, followed by a rest before carving. Those settings are specific to that recipe.

For conventional oven roasting, the USDA recommends keeping the oven at or above its minimum setting throughout cooking. A reputable recipe’s popularity does not make its lower-temperature instructions equivalent to official guidance.

Smoking is a separate case. A pellet-grill recipe may deliberately begin with a low-temperature smoking stage, then increase the heat. Its timing belongs to that equipment and recipe, not to a covered roasting pan in a kitchen oven.

How to Roast a Turkey Safely in the Oven

For oven roasting at 325°F, start with a fresh or completely thawed, unstuffed whole turkey. Cook stuffing separately so you do not have to keep roasting the meat while waiting for the center of the stuffing to heat through.

Step 1: Prepare a Fully Thawed Turkey

Keep the turkey refrigerated at 40°F or below until you are ready to prepare it. Do not leave it on the counter to warm up.
Remove the neck and giblet package from the cavities.
Pat the skin dry with paper towels. Do not rinse raw turkey; splashing water can spread bacteria around the sink and nearby surfaces.
Wash your hands and clean anything that contacted the raw bird before handling other food.

A partially frozen turkey requires a different cooking allowance. Do not use a fresh-or-thawed roasting estimate if you discover an icy cavity or frozen areas.

Step 2: Preheat the Oven and Prepare the Pan

Preheat the oven to 325°F. If your oven’s accuracy is questionable, use an oven thermometer rather than assuming the dial matches the actual temperature.
Place the turkey breast-side up on a flat wire rack in a shallow roasting pan, 2 to 2½ inches deep.
Brush the skin with vegetable oil or melted butter, then season it. Leave the cavity unstuffed.
Position the pan so air can circulate around it. An oversized pan or a turkey crowded against the oven walls can interfere with even cooking.

Use the bird’s weight to choose a planning window, not an exact removal time. Pan material, oven performance, covering, and the turkey’s starting condition can all change the finish.

Step 3: Roast and Manage Browning

Roast the turkey without repeatedly opening the oven door. Basting is optional, and every opening releases heat.
When the breast reaches the color you want, shield it with a loose aluminum-foil tent. Cover the browned area rather than tightly wrapping the entire bird.
If you choose a covered roast, account for browning before the finish.

I’d use aluminum foil over just the browned breast rather than wrapping the whole pan, so the remaining skin can keep coloring.

Do not extend an otherwise completed cook simply to make the skin darker. Skin color is a quality cue, not a measurement of the meat’s internal temperature.

Step 4: Check the Breast, Thigh, and Wing

Before removing the turkey, use a food thermometer to verify 165°F in the thickest part of the breast, the innermost part of the thigh, and the innermost part of the wing, following USDA guidance.
Keep the probe in the meat, away from bone, the roasting pan, and the open cavity. Reposition it if you suspect the tip is not sitting in the intended location.
Check more than one side if the bird appears to be cooking unevenly. Keep roasting if any required location has not reached the endpoint.

A single thigh reading is not enough. The breast and other thick areas can heat at different rates, especially in an oven with uneven heat circulation.

Do not substitute clear juices, a browned exterior, or a pop-up indicator for these thermometer checks. Also, do not remove the bird early and assume resting will make an under-temperature area safe.

Step 5: Rest and Carve

Transfer the turkey to a clean carving board and loosely tent it with foil.
Rest it for 15 to 20 minutes before carving.
Use clean utensils and a clean platter for serving, not equipment that held the raw turkey.

Include the rest in your dinner schedule. The roasting estimate is not the time from switching on the oven to putting carved turkey on the table.

How Smoking and Other Cooking Setups Change Timing

Pellet-Grill Smoking

At the start of a smoked-turkey cook, 225 to 275°F is Traeger’s recommended starting range for turkey on its pellet grills. The exact starting setting, bird size, and initial-stage duration belong to the particular Traeger smoked-turkey recipe you select.

After the initial smoking stage, Traeger’s staged method increases the grill to 350°F and gives an estimate of 3½ to 4 hours more for the finishing stage. That estimate covers the finishing stage and varies by recipe and smoker. The 3½- to 4-hour estimate applies only to Traeger’s finishing stage, so the full cook plan depends on the selected recipe’s bird size and stage instructions.

Before removing a turkey from a Traeger pellet grill, its guidance calls for 165°F in the innermost thigh, innermost wing, and thickest breast. Keep the thermometer away from bone, then rest the bird for 15 to 20 minutes before carving.

Wild Turkey and Separate Breasts

A whole-turkey roasting chart does not apply directly to a boneless breast, separated legs, or another individual cut. Their thickness and shape differ from those of an intact bird, so multiplying their weight by a whole-bird minutes-per-pound estimate can lead to overcooking.

For wild turkey, match the cooking approach to the actual cut and preparation rather than using a whole-turkey estimate. A skinless breast needs different handling from a whole, skin-on bird; an oven setting alone does not account for that difference.

Trash Can Turkey

A trash can cooking rig requires its own timing approach. Charcoal placement, airflow, wind, and the cooker’s geometry change how heat reaches the bird. The amount of charcoal is not a reliable substitute for measuring cooking conditions and meat temperature.

A vessel reserved only for food is not automatically suitable for high-heat cooking. Use equipment designed for that purpose, not a galvanized, painted, or otherwise coated container that is not approved for cooking. Charcoal cooking also belongs outdoors, never in a garage or another enclosed space.

How to Avoid Turkey Timing Surprises

The USDA identifies several reasons a turkey may finish earlier or later than a chart suggests:

Starting condition: An icy cavity can affect the cooking time.
Stuffing: A stuffed turkey takes longer because both the meat and the center of the stuffing must heat through.
Pan material: Dark roasting pans can cook faster than shiny metal pans.
Pan size and depth: Restricted airflow can slow or unevenly distribute cooking.
Covering: A foil tent used throughout roasting can slow cooking, while an oven cooking bag can accelerate it.
Oven conditions: Rack position, uneven heating, and a crowded oven can affect the result.

These are reasons to leave flexibility in the meal schedule, not reasons to invent a new precise minutes-per-pound rule.

Begin checking the meat before the earliest expected finish rather than waiting until the end of the entire estimated window. Have your thermometer, foil, carving board, and serving platter ready so a turkey that finishes early does not remain in the oven unnecessarily.

Before carving, make a quick final check:

You measured the breast as well as the dark-meat areas.
You completed the rest before slicing.

Once those checks are complete, carve and serve rather than continuing to roast for the sake of reaching a scheduled time.

Frequently Asked Questions

How Long Should a 23-Pound Stuffed Turkey Cook at 275 Degrees?

There is no recommended 275°F cooking time for a 23-pound stuffed turkey; conventional oven roasting guidance calls for at least 325°F. Use a food thermometer to decide when it is done. Both the turkey’s required checking locations and the center of the stuffing must reach 165°F. For optimum safety, cook the stuffing separately in a casserole.

Is It Better to Cook a Turkey at 250 or 350 Degrees?

Choose 350°F for conventional oven roasting; the lower option is below the USDA’s recommended oven minimum. A lower oven setting does not automatically produce juicier turkey, avoiding overcooking matters more. Use a recipe intended for your turkey’s size and preparation, and let thermometer readings determine the finish.

Is It Safe to Cook a Turkey Overnight at 250 Degrees?

An overnight whole-turkey roast at that setting does not follow USDA conventional-oven guidance, which calls for at least 325°F. Do not lower the oven simply to stretch cooking until morning. If you need to work ahead, cook the turkey using a recommended method, then promptly carve, refrigerate, and reheat it safely rather than holding a raw bird in a low oven overnight.
