Cooking a 20lb turkey can be a daunting task, especially for those who don’t cook them often. If you’re not sure how long to cook a 20lb turkey, fear not! This article will provide a comprehensive guide on cooking times, temperature, and preparation methods to ensure a perfectly cooked turkey every time.

Step-by-Step Guide

The key to cooking a 20lb turkey is preparation. Begin by cleaning the turkey, removing the giblets, and thawing it if necessary. Season or stuff the turkey as desired. Preheat the oven to 325°F and roast the turkey for 3-4 hours, or until the internal temperature reaches 165°F. Let the turkey rest for 15-20 minutes before carving.

To ensure even cooking and moist meat, baste the turkey every 30-60 minutes and tent the turkey with foil about two-thirds of the way through cooking.

Time and Temperature

Internal temperature is the most important factor in cooking a 20lb turkey. Insert a meat thermometer into the thickest part of the meat, being careful not to touch bone. The turkey is safe to eat once the internal temperature reaches 165°F.

The oven temperature should be set to 325°F for roasting a 20lb turkey. If your oven runs hot or cold, adjust accordingly. Generally, a turkey should cook for 13-15 minutes per pound, but this can vary based on oven temperature, stuffing, and other factors.

Alternative Cooking Methods

While roasting is the traditional method, there are several other ways to cook a 20lb turkey. Smoking, deep-frying, grilling, and roasting on a grill are all viable options. Smoked turkey has a unique flavor and can be cooked in a smoker or on a grill with smoking chips. Deep-fried turkey is crispy on the outside and juicy on the inside, but requires special equipment and safety precautions. Grilled turkey can be cooked directly on the grates or in a roasting pan; however, it requires more attention and can be difficult to regulate temperature. Roasting on a grill provides an alternative to the oven and can impart a smoky flavor, but requires a more hands-on approach.

Recipe Variations

There are countless ways to season and stuff a 20lb turkey. Classic stuffing made with bread, celery, onions, and sage is always a crowd-pleaser. Spicy Cajun stuffing adds a kick to the traditional recipe. Sweet and savory stuffing made with apples, cranberries, and sausage is perfect for fall. Garlic and herb turkey rub is perfect for those who prefer a simple seasoning. Herbed butter under the skin is another delicious way to flavor the turkey and keep it moist.

Top Tips for Success

Using a meat thermometer is the surest way to ensure the turkey is cooked to the safe internal temperature of 165°F. Additionally, basting the turkey regularly and tenting it with foil will keep it moist. Allowing the turkey to rest before carving ensures that the juices redistribute throughout the meat rather than being released when cut.

Other tips for success include avoiding stuffing the turkey too tightly, using a roasting pan with a rack to promote even cooking, and checking the turkey periodically to ensure it’s not overcooking or drying out.


Cooking a 20lb turkey doesn’t have to be a daunting task. With proper preparation, cooking times, and temperature, along with alternative cooking methods and recipe variations, your turkey can be the star of the Thanksgiving dinner table. Give these tips a try, and you’re sure to have a moist, flavorful turkey every time.
