How Long Should You Cook a 20 Pound Turkey at 325 Degrees Fahrenheit?

Cooking a turkey for Thanksgiving or any other holiday meal can be a daunting task, especially if it’s a large bird. A 20 pound turkey is considered quite big, so figuring out the right roasting time is crucial to ensure it turns out juicy and delicious. When cooking a turkey weighing 20 pounds at 325 degrees Fahrenheit, there are a few key factors to take into account.

Cook Time Depends on Whether It’s Stuffed

The main factor that will determine the total roasting time for your 20 pound turkey is whether you choose to stuff it or cook it unstuffed An unstuffed turkey will take less time compared to a stuffed one Here’s a breakdown of approximate cook times

• Unstuffed 20 lb turkey: Around 4 1⁄2 hours
• Stuffed 20 lb turkey: From 4 1⁄4 hours to 4 3⁄4 hours

Stuffing adds mass and insulation to the turkey which slows down the cooking process. The stuffing must reach a safe internal temperature of 165 degrees Fahrenheit before the turkey can be removed from the oven. An unstuffed turkey will cook faster since heat can directly penetrate and cook the meat.

Key Things to Keep in Mind

To ensure your 20 pound turkey turns out juicy, tender and fully cooked, keep these tips in mind:

• Always use a meat thermometer to check the internal temperature. The thigh should reach 165 degrees Fahrenheit.
• Calculate roasting time based on a 325 degree Fahrenheit oven temperature. Higher temperatures will cook the turkey faster while lower temps will extend the roasting time.
• Let the turkey rest for 20-30 minutes before carving it. This allows the juices to redistribute throughout the meat.
• Use a roasting pan that is at least 2 to 2 1⁄2 inches deep and large enough to accommodate the turkey. This prevents overflow and promotes even cooking.
• Basting the turkey with pan juices or butter/oil helps keep the skin from drying out. Baste every 30-45 minutes.
• Tent the turkey with foil if the skin starts browning too quickly. This prevents it from burning or becoming overly dry.

Handy Time Chart for 20 Pound Turkey

For easy reference, here is a chart summarizing approximate cook times for a 20 pound turkey:

The cook times above are based on roasting at 325 degrees Fahrenheit. Any variations in temperature or other factors like a frozen turkey may affect the total time required.

Always rely on a meat thermometer over cook times to determine doneness and ensure food safety. But this handy guide takes the guesswork out of roughly how long you can expect your 20 pound bird to require in the oven.

Other Factors That Can Impact Cook Time

There are a few other things that can increase or decrease the overall roasting duration for your 20 lb turkey:

• Frozen turkey – A frozen bird will take considerably longer to roast, potentially twice as long depending on the level of frozenness. Be sure to allot extra time if not fully thawed.

• Cooking method – Using a convection oven or deep frying the turkey will cook it faster than a standard oven. Adjust times accordingly.

• Temperature – Higher oven temps above 325°F will decrease cooking time while lower oven temps will increase it.

• Brining – Soaking the turkey in a saltwater brine before roasting will add moisture and tend to speed up cooking a bit.

• Turkey shape – Turkeys that are very lopsided or irregularly shaped may require additional roasting time if some parts are much thicker.

When working with a sizeable 20 pound turkey in your oven, allowing enough roasting time for it to fully cook through to a safe internal temperature is crucial. Keeping the turkey moist and flavorful is also a must for a memorable holiday meal. By following the guidelines above for roast times, using a meat thermometer and tenting to prevent burning, you’ll be rewarded with a perfectly cooked 20 pound turkey this season.
