The big one, handled
Thanksgiving dinner for 12, without the panic.
What size turkey, how much of every side, when to thaw, and what to do each day of the week — the whole plan on one page.
The turkey: size and thaw time first
For 12 people, buy a 15–18 lb turkey — the standard 1¼–1½ lb per person for a bone-in bird. That lands everyone a real portion plus the leftovers that are half the point of Thanksgiving.
The mistake that actually ruins Thanksgivings isn’t the size — it’s the thaw. A frozen turkey needs roughly 24 hours in the fridge per 4–5 lb:
| Turkey size | Fridge thaw time | Move it to the fridge by |
|---|---|---|
| 12–14 lb | 3 days | Monday morning |
| 15–18 lb | 4 days | Sunday morning |
| 19–22 lb | 5 days | Saturday morning |
Roasting runs about 13 minutes per pound at 350°F unstuffed — roughly 3½–4 hours for a 16-pounder — and it’s done when the thigh reads 165°F. Trust a thermometer, not the clock, and give the bird 30 minutes of rest while the sides finish.
Every side, scaled for 12
| Dish | Amount for 12 | Buying note |
|---|---|---|
| Mashed potatoes | 6 lb potatoes | Russets or Yukon Golds — about ½ lb per person |
| Stuffing | 12 cups prepared | Two 14-oz bags, or 1½ loaves if homemade |
| Gravy | 3 cups | ¼ cup per person — people always want more; 4 cups is safer |
| Green beans | 3 lb | 4 oz per person, trimmed |
| Sweet potatoes | 4 lb | One 9×13 casserole covers 12 |
| Cranberry sauce | 3 cups | Two 14-oz cans, or one 12-oz bag of fresh cranberries |
| Dinner rolls | 18 | 1½ each — and the easiest thing to buy, not bake |
| Pie | 2–3 pies | 8 slices each; two flavors beats two of the same |
The week, in order
- Weekend before: Shop everything nonperishable. Order the turkey if fresh; move it to the fridge Sunday if frozen.
- Tuesday: Make cranberry sauce and pie dough — both hold beautifully. Confirm headcount and ask the dietary question now, not Thursday.
- Wednesday: Bake pies. Assemble casseroles up to the point of baking. Chop everything choppable. Set the table tonight — Thursday-you will be grateful.
- Thursday morning: Turkey in by mid-morning for a 3pm dinner. Potatoes peeled and held in cold water.
- The last hour: Bird rests under foil while casseroles and rolls rotate through the oven, potatoes get mashed, and gravy comes together from the drippings.
The one-oven bottleneck is the real constraint — everything above is sequenced so the turkey leaves the oven before the sides go in. If a dish can be served at room temperature (cranberry, rolls, some casseroles), let it be.
What to buy instead of make
Rolls, one of the pies, and the cranberry sauce are the classic buys — nobody has ever left a Thanksgiving muttering about canned cranberry. Spend your effort where it shows: the bird, the potatoes, the gravy, and whichever side is yours. Store-bought is fine. Two mothers we trust insist on it.
