Formula
Turkey Weight = Guests x Lbs per Person | Cook Time = Weight x 13 min/lb (unstuffed)
Turkey weight is calculated by multiplying the number of guests by the desired pounds per person (typically 1.5 lbs for bone-in). Cooking time assumes 325 degrees F at 13 minutes per pound unstuffed or 15 minutes per pound stuffed.
Worked Examples
Example 1: Classic 12-Person Thanksgiving
Problem: You are hosting 12 guests for Thanksgiving with 1.5 lbs turkey per person, 5 sides, and 1 pie per 6 guests.
Solution: Turkey: 12 x 1.5 = 18 lbs\nCook time (unstuffed): 18 x 13 = 234 min = 3.9 hours\nPies needed: 12 / 6 = 2 pies\nMashed potatoes: 12 x 0.5 = 6 lbs\nRolls: 12 x 2 = 24 rolls\nGravy: 12 / 3 = 4 cups = 1.0 quart
Result: 18 lb turkey, 3.9 hrs cook time, 2 pies, 6 lbs potatoes, 24 rolls, 1 qt gravy
Example 2: Large Family Gathering of 25
Problem: A large Thanksgiving for 25 guests with 1.5 lbs turkey per person, 6 sides, and 1 pie per 6 guests.
Solution: Turkey: 25 x 1.5 = 37.5 lbs (suggest two turkeys)\nCook time per 19-lb turkey: 19 x 13 = 247 min = 4.1 hours\nPies needed: 25 / 6 = 5 pies\nMashed potatoes: 25 x 0.5 = 12.5 lbs\nRolls: 25 x 2 = 50 rolls\nGravy: 25 / 3 = 8.3 cups = 2.1 quarts
Result: 37.5 lbs turkey (2 birds), 5 pies, 12.5 lbs potatoes, 50 rolls, 2.1 qt gravy
Frequently Asked Questions
How much turkey should I buy per person for Thanksgiving?
The general rule is 1 to 1.5 pounds of whole turkey per person. For bone-in turkey, use 1.5 pounds per person because roughly 40% of the weight is bone and will not be edible meat. If you want generous leftovers for sandwiches and soup, plan for up to 2 pounds per person. For boneless turkey breast, you can reduce that to about 0.75 pounds per person since there is minimal waste. A 12-person dinner typically requires an 18 to 20 pound turkey. If your crowd is especially large, consider cooking two smaller turkeys rather than one enormous bird, as smaller turkeys tend to cook more evenly and have better texture.
How many side dishes should I prepare for Thanksgiving dinner?
Most Thanksgiving meals include between 4 and 7 side dishes alongside the turkey. The classic essentials are mashed potatoes, stuffing or dressing, cranberry sauce, gravy, and a green vegetable like green bean casserole. Beyond these, popular additions include sweet potatoes or yams, dinner rolls, corn, roasted vegetables, salad, and macaroni and cheese. Plan for approximately half a cup of each side dish per person. For a crowd of 12, that means each dish should yield about 6 cups or roughly 12 half-cup servings. Having a variety ensures guests with dietary restrictions can find suitable options and everyone has their favorites represented at the table.
How do I calculate how many pies to make for Thanksgiving?
A standard 9-inch pie typically yields 6 to 8 slices, depending on how generous you cut them. For Thanksgiving, assume each guest will eat at least one slice, with many wanting to sample multiple pie varieties. A good rule of thumb is one pie for every 6 guests if you are serving two or more varieties, as people tend to take smaller slices when they want to try different flavors. For 12 guests with two pie varieties, make 4 pies total to ensure everyone gets at least one slice of each kind. Popular Thanksgiving pie flavors include pumpkin, pecan, apple, and sweet potato. Consider that some guests may skip dessert entirely while pie enthusiasts will eat two or three slices.
How far in advance should I start preparing Thanksgiving dinner?
Thanksgiving preparation should begin several days before the actual meal for best results. Two to three days ahead, thaw your frozen turkey in the refrigerator, allowing 24 hours of thawing time for every 4 to 5 pounds of turkey. Two days before, prepare any make-ahead sides like cranberry sauce and pie dough. The day before, bake pies, prepare casserole bases, chop vegetables, make stuffing mixture, and set the table. On Thanksgiving morning, start the turkey first since it takes the longest. While the turkey cooks, prepare hot side dishes and time them to finish during the turkey rest period. This staggered approach prevents kitchen chaos and ensures everything reaches the table hot and fresh.
