Select your leftover preference. "Some leftovers" adds about 25% more food, while "lots of leftovers" adds 50% - perfect for turkey sandwiches the next day.

Choose whether you're using a fresh or frozen turkey and your preferred cooking method. The calculator adjusts thaw time and cook time accordingly.

Toggle the side dishes you plan to serve. The calculator provides quantities for each selected side.

Understanding Your Results

The turkey size is rounded to common weights available at grocery stores. If your calculated size falls between standard sizes, go larger.

Cook time is for an unstuffed turkey. Add 15-30 minutes if stuffing the turkey. Always verify doneness with a meat thermometer.

The cooking timeline helps you coordinate multiple dishes and ensures everything is ready at the same time.

Frequently Asked Questions

How many pounds of turkey per person?

Plan for 1-1.25 pounds of turkey per adult and 0.75 pounds per child. This accounts for bone weight and provides generous portions. For leftovers, add 25-50% more. A 15-pound turkey serves about 10-12 people.

How long does it take to thaw a frozen turkey?

In the refrigerator: allow 24 hours for every 4-5 pounds. A 16-pound turkey needs 3-4 days. In cold water: 30 minutes per pound, changing water every 30 minutes. Never thaw at room temperature.

How long to cook a turkey?

At 325°F, unstuffed: 13-15 minutes per pound. Stuffed: 15-17 minutes per pound. A 15-pound unstuffed turkey takes about 3.5-4 hours. Always use a meat thermometer - internal temp should reach 165°F in the thickest part of the thigh.

Should I stuff my turkey?

While traditional, stuffing inside the turkey increases cooking time and food safety risks. Cooking stuffing separately (dressing) is safer and allows for crispier top. If stuffing, ensure the center reaches 165°F.

How do I make turkey gravy?

Use pan drippings: skim off excess fat, add flour (2 tbsp per cup of liquid), whisk constantly, add turkey or chicken stock until desired consistency. Simmer 5-10 minutes. Season to taste. Make 1/4 cup gravy per person.

What side dishes go with turkey?

Classic sides: mashed potatoes, gravy, stuffing/dressing, cranberry sauce, green bean casserole, sweet potato casserole, dinner rolls, roasted vegetables. Plan 3-5 sides plus bread and dessert. About 1/2 cup of each side per person.

How do I plan my cooking timeline?

Work backwards from dinner time. Turkey needs to rest 30-45 minutes after cooking. Calculate cook time, then add 1 hour for prep and resting. Casseroles can share oven space. Make pies and cranberry sauce a day ahead.

How do I keep turkey moist?

Brine turkey 12-24 hours before (or buy pre-brined). Butter under the skin. Start breast-side down, flip halfway. Baste every 45 minutes. Tent with foil if browning too fast. Most importantly: don't overcook! Use a thermometer.
