Thanksgiving Planner

Thanksgiving Dinner Planner Calculator

This thanksgiving dinner calculator doubles as a turkey portion calculator: enter your guest count and serving time — get the turkey size, thaw schedule, roast times, side-dish portions for your headcount, a minute-by-minute cooking timeline, and a leftover estimate. Free, private, runs entirely in your browser.

What this planner covers (and what it doesn't)

This is a full Thanksgiving dinner planner: guest count → turkey size in pounds, thaw time, roast time, side-dish quantities, a countdown cooking timeline from your serve time, and a leftover estimator — one integrated plan. Think of it as a thanksgiving menu planner, not a single-number tool.

Thawing deep-dive? Go to the Turkey Defrost Calculator — fridge, cold-water and microwave methods with a reverse start-date planner and a full USDA food-safety panel.
Sizing the bird itself? Go to the Turkey Size Calculator — whole vs. bone-in breast vs. boneless, fry and smoke times, and the verbatim USDA roast chart.

The three tools link to each other and do not duplicate: this page plans the dinner; the other two go deep on the turkey.

The turkey is done at 165°F internal temperature — the clock is a guide, the thermometer is the proof.

Worked example: Thanksgiving for 12

The scenario

12 adults, normal appetites, some leftovers wanted, serving at 4:00 PM, stuffing cooked separately.

The plan (computed by the planner)

Buy a 15 lb turkey (12 guests × 1 lb × 1.25 leftovers, rounded up).
Thaw: 90 h 00 min (3.75 days) in the fridge — start 4 full days before serving; or 7 h 30 min in cold water (15 water changes).
Roast unstuffed at 325°F: 3 h 53 min to 4 h 15 min; done at 165°F on a thermometer.
Sides for 12: 9 cups stuffing, 9 cups mashed potatoes (4 lb raw), 4.8 cups cranberry sauce, 3 lb vegetables, 4 cups gravy, 18 rolls, 2 pies.
Timeline: preheat at 10:30 AM · turkey in at 11:15 AM · start temp checks 11:37 AM · out to rest 3:30 PM · carve 3:50 PM · serve 4:00 PM.
Leftovers: about 3 lb raw-equivalent → 1.65 lb cooked ≈ 6.6 cups shredded ≈ 13 sandwiches.

How the planner does the math

Turkey size: 1 lb per person

USDA guidance is about 1 lb of whole turkey per adult — bone-in birds lose a lot of weight to bone and shrinkage. Kids under 10 count as half a serving. Appetite multiplies that base (light ×0.85, big ×1.25) and your leftover goal multiplies it again (some ×1.25, a week ×1.5). The planner rounds up to the next whole pound because that's the bird you actually buy.

Thaw: 24 hours per 4 lb

USDA says allow about 24 hours of fridge thawing per 4–5 lb. The planner uses the conservative 4-lb figure, then rounds up to whole days — thawing a day early is harmless (a thawed turkey keeps 1–2 more days in the fridge), thawing a day late is a disaster. Cold-water thawing is 30 minutes per lb with the water changed every 30 minutes, and the bird must be cooked immediately after.

Timeline: plan on the high end

The roast chart gives a range (for example, a 15 lb unstuffed bird: 3 h 53 min to 4 h 15 min). The timeline schedules oven-in on the high end and starts thermometer checks at the low end. A finished turkey can rest tented in foil — an undercooked one can't be hurried without drying out. Rest 30 minutes before carving.

Sides: per-person portions

Side quantities scale linearly per guest from Food Network's Thanksgiving portion planner: ¾ cup stuffing, ¾ cup mashed potatoes (≈⅓ lb raw potatoes), ⅖ cup cranberry sauce, ¼ lb vegetables, ⅓ cup gravy, 1½ rolls per guest, and 1 pie per 7 guests.

Food safety (USDA)

Turkey is done at 165°F — check the thickest part of the breast, the innermost thigh, and the innermost wing with a food thermometer, even if the bird has a pop-up timer.
Stuffing cooked inside the bird must also reach 165°F in its center. USDA recommends cooking stuffing separately.
Never thaw on the counter — the danger zone is 40°F to 140°F. Refrigerate leftovers within 2 hours; use within 3–4 days.

Thanksgiving dinner FAQ

How much turkey per person for Thanksgiving dinner?

If you are wondering how many pounds of turkey per person to buy, plan on about 1 lb of whole turkey per adult — the USDA rule of thumb. So 12 adults need a 15 lb bird when you want some leftovers (12 × 1 × 1.25, rounded up), or about 12 lb for just dinner. Kids under 10 count as half a serving.

How much turkey for 12 people?

For 12 adults with normal appetites and some leftovers planned, buy a 15 lb turkey. Want a full week of leftovers? Scale up to about 18 lb (12 × 1.5). Use the planner above for your exact headcount.

Do kids count as full servings at Thanksgiving?

So do kids count as full servings? For Thanksgiving planning, no — count each child under 10 as half an adult serving. For example, 6 adults plus 4 kids equals 8 adult-equivalents, which needs about a 10 lb turkey with some leftovers planned.

How long does it take to thaw a Thanksgiving turkey?

In the refrigerator, about 24 hours per 4 lb — a 15 lb turkey needs 90 h 00 min (3.75 days), so start 4 full days before serving. In cold water it takes 30 minutes per lb (7 h 30 min for 15 lb), with the water changed every 30 minutes, and the bird must be cooked immediately after.

When to start thawing turkey for Thanksgiving 2026?

Thanksgiving 2026 is Thursday, November 26, 2026. Count back whole thaw days from your serve date: a 15 lb turkey needs 4 full fridge days, so start thawing by the morning of Sunday, November 22, 2026.

How long to cook a 15 pound turkey?

Roasted unstuffed at 325°F, a 15 lb turkey takes about 3 h 53 min to 4 h 15 min. It is done when a food thermometer reads 165°F in the thickest part of the breast, the innermost thigh, and the innermost wing — then rest it 30 minutes before carving.

What time to put turkey in the oven on Thanksgiving?

Work backwards from serve time on the high end of the cook range. Serving at 4:00 PM with a 15 lb unstuffed turkey (up to 4 h 15 min roast + 30 min rest), put the bird in at about 11:15 AM and start checking the temperature around 11:37 AM. The planner above builds this schedule for any serve time.

How much stuffing per person?

Plan ¾ cup of cooked stuffing per guest — for 12 guests that is 9 cups. Wondering how much mashed potatoes per person too? Plan ¾ cup per guest as well (9 cups for 12, about 4 lb of raw potatoes).

How much gravy per person?

About ⅓ cup of gravy per guest — 4 cups for 12 guests. For cranberry sauce, plan ⅖ cup per guest (how much cranberry sauce per person works out to 4.8 cups for 12).

How many pies for Thanksgiving do I need?

Plan 1 pie per 7 guests — 2 pies for 12 guests. If pie is the main event at your table, round up.

How much leftover turkey will I have?

A 15 lb turkey feeding 12 adults leaves roughly 3 lb of raw-weight equivalent — about 1.65 lb of cooked meat, or 6.6 cups shredded, enough for about 13 hearty sandwiches. That is how much leftover turkey per person to expect: about 0.25 lb raw-equivalent each. This is an estimate; cooked meat averages about 55% of raw weight.

What internal temperature is turkey done?

165°F, measured with a food thermometer in three places: the thickest part of the breast, the innermost part of the thigh, and the innermost part of the wing. Stuffing cooked inside the bird must reach 165°F in its center too. Pop-up timers are a backup, not a replacement.

How is this different from a turkey size calculator?

A turkey size calculator answers one question — how big a bird to buy. This Thanksgiving dinner planner builds the whole event: turkey size plus thaw schedule, roast times, side-dish portions for your headcount, a countdown cooking timeline from serve time, and a leftover estimate. For a deep dive on thawing methods, see our turkey defrost calculator; for sizing whole vs. boneless birds, see our turkey size calculator.
