Nesco Roaster Turkey Cooking Times

The clock is only a planning tool: use a food thermometer to decide when the turkey is finished, and allow extra time for a large bird, a frozen bird, or a roaster that runs cool.

Use this chart to plan dinner timing for a conventional covered roaster oven. These ranges are for a completely thawed, unstuffed turkey.

Turkey Weight	Typical Cooking Time	Planning Note
8–12 pounds	2¾–3 hours	Start checking before the end of the range.
12–14 pounds	3–3¾ hours	Use a food thermometer to confirm doneness.
14–18 pounds	3¾–4¼ hours	A 16-pound turkey falls in this range.
18–20 pounds	4¼–4½ hours	Use a food thermometer to confirm doneness.
20–24 pounds	4½–5 hours	For a turkey weighing exactly 20 pounds, use this larger planning range.

Actual timing can vary when the lid is lifted. Confirm the timing guidance for your specific appliance in its use-and-care manual.

Which Nesco Roaster You Have Changes the Timing

A standard Nesco roaster oven is a covered countertop roasting oven with an insert pan and rack. It cooks a whole turkey much like a conventional oven, while freeing up the main oven for side dishes.

The Nesco High-Speed Vertical Turkey Roaster is different. It uses a vertical poultry holder and a dedicated timed cooking system, so its cooking instructions do not match the conventional-roaster chart.

Do not use a high-speed vertical roaster’s timer as a conversion for a conventional Nesco roaster oven.

Before you start, make sure the turkey fits comfortably below the lid with room for air to circulate. A turkey pressed against the lid may cook unevenly and can make it difficult to remove the bird safely.

How to Cook a Turkey in a Conventional Nesco Roaster

Step 1: Prepare the Turkey and Roaster

Thaw the turkey completely before cooking whenever possible. Remove the wrapper, neck, and giblet packet.
Do not rinse the turkey; rinsing can splash raw poultry juices onto nearby counters and utensils.
Pat the turkey dry, season it as desired, and place it breast-side up on the roasting rack inside the insert pan.
Keep stuffing out of the turkey cavity for the most predictable cooking time. Bake stuffing separately in a casserole dish.
Put the lid on the roaster and make sure it sits flat without touching the turkey.

Step 2: Preheat and Set the Cooking Plan

Preheat the conventional Nesco roaster to 325°F.
Choose the cooking-time range for the turkey’s weight from the table, then plan to have the bird ready before guests expect to eat. The time range is an estimate, not a finish line.
Start timing when the turkey goes into the hot roaster.
Keep the lid closed while the turkey cooks. A covered electric roaster retains heat well, but lifting the lid releases heat and can lengthen the cooking time.

Step 3: Check the Internal Temperature

Near the end of the planned cooking range, check the turkey with a reliable food thermometer.

Insert the probe into the thickest part of the breast without touching bone.
Check the innermost part of the thigh and wing as well.
Check the thickest part with a thermometer; the recommended internal temperature is 165°F. If any spot is cooler, replace the lid and continue cooking before checking again.

Color, clear juices, and a popped-up timer can be useful clues, but they do not replace a thermometer.

Step 4: Rest Before Carving

Transfer the turkey to a carving board or platter and rest it for 20 minutes before carving. Loosely tenting it with foil after cooking helps hold warmth without trapping a great deal of steam against the skin.

A rest gives the juices time to settle in the meat, making the turkey easier to carve neatly. Confirm any model-specific resting direction in your roaster manual or recipe if it differs from this conventional-roaster approach.

Special Cases That Change Turkey Cooking Time

Vertical, frozen, and stuffed turkeys require adjusted timing and thermometer checks before serving.

Nesco High-Speed Vertical Turkey Roaster

Assemble the drip tray and poultry holder as directed for the vertical roaster.
Season the turkey and position it on the holder so it is stable and centered.
Set the timer for 6 minutes per pound, following the Nesco High-Speed Vertical Turkey Roaster instructions.
When the cycle ends, check the thickest part of the turkey with a thermometer; it must reach 165°F.
Rest the turkey for 10 to 15 minutes before carving, as directed for this model.

Cooking a Frozen Turkey

A frozen turkey needs 50% more time than normal oven cooking times. Do not use the standard timing chart without making that adjustment, and do not stuff a turkey that starts frozen.

Because the cooking process is less predictable, use a thermometer in the breast, thigh, and wing before serving.

Cooking a Stuffed Turkey

A stuffed turkey takes longer and is harder to time because the center of the stuffing must heat safely along with the bird. For the most reliable result, cook the turkey unstuffed in the roaster and bake dressing separately.

If you choose to stuff the turkey anyway, do not rely solely on the unstuffed timetable. Check both the turkey and stuffing with a thermometer; each must reach 165°F before serving.

Confirm Doneness and Make Next Time Easier

Before carving, use this short final check:

The thermometer reads 165°F in the thickest breast, innermost thigh, and wing.
The probe has not touched bone, the roasting rack, or the pan.
The turkey has rested long enough to carve cleanly.
You have a clean carving board and platter ready before moving the hot bird.

For future holiday meals, write down the turkey’s weight, the actual cooking time, and whether the lid was opened. That small note is more useful than a generic per-pound formula because it reflects how your own roaster performs.

Frequently Asked Questions

How long does a 13-pound turkey take in a Nesco roaster?

A fully thawed, unstuffed 13-pound turkey needs about 3 to 3¾ hours in a conventional Nesco roaster. Use that window to plan the meal, then cook until the thermometer confirms the turkey is safely done.

How long does a 16-pound turkey take in a Nesco roaster?

A fully thawed, unstuffed 16-pound turkey typically takes 3¾ to 4¼ hours in a conventional Nesco roaster. Keep the lid closed as much as possible and verify doneness with a thermometer rather than extending the cook just because the full time range has not elapsed.

How long does a 20-pound turkey take in a roaster?

A 20-pound, fully thawed, unstuffed turkey needs about 4½ to 5 hours in a conventional roaster. Use a thermometer to confirm doneness.

Is it better to cook a turkey at 325 or 400?

For a conventional Nesco roaster, 325°F is the better baseline because the standard turkey timing ranges are built around that moderate roasting temperature. A higher-temperature setting browns the outside more aggressively and does not use the same dependable timetable.

How long does a turkey take in a roaster at 350?

A 350°F cook time needs a model-specific schedule, so do not convert the conventional 325°F chart into a fixed per-pound rule. If your appliance instructions call for 350°F, use that model’s guidance and finish based on the internal temperature, not elapsed time.

Can I wrap foil around the turkey in a Nesco roaster?

Do not wrap the whole turkey in foil while it cooks in a conventional roaster. Foil traps steam against the skin and works against browning; use a loose foil tent only after the turkey comes out of the roaster to rest.

How long does a 12-pound turkey take in a Nesco roaster?

For a fully thawed, unstuffed 12-pound turkey in a conventional Nesco roaster, allow about 2¾ to 3 hours. Begin checking near the end of that range, and do not serve it until the thickest part reaches 165°F.
