Cooking a turkey, especially a large 20 lb bird, can seem daunting. Getting the timing right is crucial to ensure a moist, perfectly cooked centerpiece for your Thanksgiving or holiday feast. This guide provides you with everything you need to know about cooking a 20 lb turkey, ensuring it’s cooked to perfection and safe to eat.
Cooking Time for a 20 lb Turkey
The general rule of thumb is to cook a turkey for 13 minutes per pound when roasting at 350°F (175°C) if unstuffed, and 15 minutes per pound if stuffed. For a 20 lb turkey, this translates to:
| Turkey Type | Weight | Approximate Cooking Time |
|---|---|---|
| Unstuffed Turkey | 20 lbs (9 kg) | 4 hours 20 minutes |
| Stuffed Turkey | 20 lbs (9 kg) | 5 hours |
These times are estimates, and it’s essential to use a meat thermometer to ensure your turkey is cooked to a safe internal temperature.
Factors Affecting Turkey Cooking Time
Several factors can influence how long it takes to cook a 20 lb turkey:
Turkey Weight and Size
While we’re focusing on a 20 lb turkey, remember that even within this weight range, slight variations exist. A slightly larger or denser 20 lb turkey might require a bit more cooking time. Always start checking for doneness earlier than the estimated time to avoid overcooking.
Fresh vs. Frozen Turkey
Frozen turkeys need to be completely thawed before cooking to ensure even cooking. Cooking times provided are for fully thawed turkeys. If your turkey is still partially frozen, it will take significantly longer to cook, and it may cook unevenly, leading to dry breast meat and undercooked thighs. Always ensure your 20 lb turkey is fully thawed before roasting.
Stuffed vs. Unstuffed Turkey
Stuffing a turkey increases the cooking time because the stuffing needs to reach a safe internal temperature of 165°F (75°C). The turkey meat surrounding the stuffing will also cook slower. If you choose to stuff your 20 lb turkey, factor in the additional cooking time and always check the temperature of both the turkey meat and the stuffing.
Oven Temperature Accuracy
Oven temperatures can fluctuate, and not all ovens are accurately calibrated. Using an oven thermometer to verify your oven temperature is crucial. If your oven runs cooler than indicated, your 20 lb turkey will take longer to cook.
Step-by-Step Guide to Cooking a 20 lb Turkey
-
Prep the Turkey: Remove the giblets and neck from the turkey cavity. Pat the turkey dry inside and out with paper towels. This helps the skin crisp up during roasting.
-
Thaw Properly: If your turkey is frozen, ensure it’s completely thawed. The safest way to thaw a turkey is in the refrigerator, allowing 24 hours for every 5 pounds of turkey. A 20 lb turkey will take approximately 4 days to thaw in the refrigerator.
-
Seasoning: Season your 20 lb turkey generously inside and out with salt, pepper, and any herbs or spices you prefer. Consider rubbing butter or oil under the skin of the breast for extra moisture and flavor.
-
Roasting: Place the turkey on a roasting rack in a roasting pan. This allows for better air circulation and prevents the bottom of the turkey from steaming. Add about a cup of water or broth to the bottom of the pan to create steam and keep the turkey moist. Preheat your oven to 350°F (175°C).
-
Initial Roasting: Roast the 20 lb turkey for the initial estimated time based on whether it’s stuffed or unstuffed.
-
Check Temperature: Begin checking the internal temperature of the turkey after about 3 hours for an unstuffed turkey and 4 hours for a stuffed turkey. Insert a meat thermometer into the thickest part of the thigh, without touching the bone.

-
Continue Roasting: Continue roasting until the thigh meat reaches an internal temperature of 165°F (75°C). If you are cooking a stuffed 20 lb turkey, ensure the stuffing also reaches 165°F (75°C) in the center.
-
Tent with Foil (If Needed): If the turkey skin is browning too quickly before the internal temperature is reached, loosely tent the breast with aluminum foil to prevent over-browning. Remove the foil during the last 30-45 minutes to allow the skin to crisp.
-
Resting Time: Once the turkey is cooked, remove it from the oven and let it rest for at least 30 minutes before carving. This resting period is crucial as it allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful turkey. The internal temperature may continue to rise slightly during resting (carry-over cooking).
Ensuring Food Safety
Food safety is paramount when cooking poultry. Always ensure your 20 lb turkey reaches a minimum internal temperature of 165°F (75°C) in the thigh to kill any harmful bacteria. For stuffed turkeys, the stuffing must also reach this temperature. Using a reliable meat thermometer and checking the temperature in multiple locations is crucial for food safety.
Make Gravy While the Turkey Rests
Use the resting time of your 20 lb turkey to prepare a delicious gravy using the pan drippings. This is an efficient way to utilize the flavorful juices and have your gravy ready to serve alongside your perfectly roasted turkey.
Carving Your 20 lb Turkey
After allowing your 20 lb turkey to rest for at least 30 minutes, it’s time to carve and serve. Resting makes carving easier and prevents the turkey from drying out.
Cooking a 20 lb turkey to perfection is achievable by following these guidelines and using a meat thermometer. Enjoy your delicious and safely cooked holiday centerpiece!
