Good to know: Scope: planning amounts for a home Thanksgiving dinner built around a whole turkey. Turkey size uses USDA guidance: about 1 lb per person, 1½ lb for hearty eaters or plenty of leftovers, and 1¼ lb for a frozen pre-stuffed turkey. Thawing and buying dates use the USDA FSIS rules (24 hours in the fridge for every 4 to 5 lb; buy a fresh turkey 1 to 2 days before cooking). Side dishes and pies have no official portion rule, so they use the servings and slices you enter; check your own recipes. Excludes turkey breasts, boneless roasts, ham, vegetarian mains, costs, nutrition and roasting times (use the Turkey Thawing & Roasting Time Calculator for those). Independent ToolsKo planner.

How to use it (step by step)

Words to know
- Per-person rule
- A quick buying guide: USDA suggests about 1 pound of whole turkey for each guest. The bones are part of that pound.
- Batch
- One full recipe as written. If a recipe serves 8 and you need 20 servings, you make 3 batches.
- Pre-stuffed turkey
- A frozen turkey sold already stuffed. USDA says cook it straight from frozen; never thaw it first.
- Shallow containers
- Low, wide food boxes. Leftovers cool fast in them, which keeps bacteria from growing.
