How to plan Thanksgiving dinner without the Thursday panic

Planning Thanksgiving dinner comes down to five decisions made in the right order: how many people, what's on the menu, who brings what, when you shop, and when each dish goes in the oven. Make those decisions three weeks out and the day itself becomes a schedule you follow instead of a scramble.

Here's the full plan, with quantities, a timeline and a budget.

Step 1: Lock the headcount and the space

Everything else depends on the number of guests. Ask for RSVPs three weeks out and count kids separately, since they eat less. Then check the practical limits:

• Seats and table space. Do you need to borrow chairs or a folding table?
• Oven space. A standard oven holds the turkey or two casserole dishes at a time, not both. This decides how many dishes can be baked on the day.
• Fridge space. A thawing turkey takes up a whole shelf for days.

Step 2: Build a menu that fits your oven

A balanced menu has one main, two or three starches, two vegetables, one or two breads or rolls, gravy and cranberry sauce, and two desserts. Then sort each dish by where it cooks:

If more than three dishes need the oven at the same time, move one to the slow cooker, ask a guest to bring it, or pick a stovetop recipe instead.

Step 3: Get the quantities right

Rules of thumb that work for most families:

• Turkey: about 1 to 1.5 pounds per person (bone-in). Go higher if you want leftovers.
• Mashed potatoes: about half a pound of raw potatoes per person.
• Stuffing: about three-quarters of a cup per person.
• Gravy: about a third of a cup per person.
• Rolls: two per person.
• Pie: one 9-inch pie serves about eight.

A frozen turkey needs roughly one day in the fridge for every four to five pounds, so a 16-pound bird needs about four days. Write the move-to-fridge date on your calendar.

Step 4: Assign dishes to guests

Most guests want to help. Give them specific jobs rather than "bring anything": a named side dish, the rolls, a pie, drinks, or ice. Keep the turkey, gravy and anything that needs your oven at the last minute for yourself. Write every assignment next to the dish on the menu so nothing is doubled.

Step 5: Follow a three-week timeline

1. Three weeks out: confirm the headcount, finalize the menu, assign dishes and order a fresh turkey if you want one.
2. Two weeks out: buy non-perishables: canned goods, broth, flour, sugar, spices, foil pans, drinks and paper goods. Prices on staples are often good this week.
3. One week out: make cranberry sauce, and check your roasting pan and meat thermometer.
4. Sunday or Monday: move a frozen turkey to the fridge (earlier for big birds). Buy fresh produce, dairy and bread.
5. Wednesday: bake pies, chop vegetables, assemble casseroles, make the gravy base and set the table.
6. Thursday: follow the day-of schedule below.

Step 6: Write the day-of schedule backward from dinner

Pick dinner time, then work backward. For a 4:00 p.m. dinner with a 14-pound turkey:

Cooking times vary by oven and turkey size, so rely on a thermometer, not the clock. The USDA recommends 165°F in the thickest part of the breast, the innermost part of the thigh and the wing.

A simple Thanksgiving budget

Tools that help

Our Meal Planner & Grocery List ($3.99) has a dinner plan and prep page, a grocery list sorted by aisle, and pantry and freezer inventories, which is exactly what you need to shop once and avoid a Wednesday-night run to the store.

The Christmas Budget & Gift Planner ($4.99) includes a holiday menu, holiday grocery list and a to-do timeline that work just as well for Thanksgiving. Both are part of the Holiday Season Bundle ($15.99), along with a sinking funds tracker for saving ahead next year.

And for the person who's already thinking about Friday's sandwiches, there's our "Leftovers Planned in Advance" design.

Common Thanksgiving planning mistakes

• Forgetting the thaw. A frozen turkey on Wednesday morning is too late.
• Too many oven dishes. Plan the oven schedule before you plan the recipes.
• No space for leftovers. Clear fridge space and buy containers ahead.
• Doing everything yourself. Delegation is part of the plan, not a failure of it.
