Thanksgiving turkey plan (12-lb base) — scaled ingredients

  • whole turkey (thawed)(≈ 1.5 lb per person raw)12 oz
  • kosher salt (dry brine)(1 tbsp/4 lb turkey, 24-48h in advance)3 tbsp
  • unsalted butter (under skin)1/2 cup
  • fresh sage + thyme + rosemary6 count
  • yellow onion (quartered)1 count
  • stock for pan2 cup
  • mashed potatoes(per person raw potato ≈ 0.5 lb)1 cup
  • stuffing3/4 cup
  • gravy1/2 cup
  • cranberry sauce1/4 cup

Cook note: Cook time scales with the cube root of mass, not linearly. An 18-lb bird = about 4h, not 4h40. Always use a probe thermometer; weight math is a starting point.

Method

  1. Count backward: bird size = 1-1.25 lb raw per adult (1.5 lb if you want leftovers for 3+ days).
  2. Thaw in fridge at 4-5 lb per day. A 14-lb bird needs 3 days. Never thaw on the counter.
  3. Dry brine 24-48 hours ahead with 1 tbsp kosher salt per 4 lb, uncovered on a rack in the fridge.
  4. Roast breast-side-up at 325°F. Pull breast at 160°F (it rises to 165°F resting). Thighs should hit 175°F.
  5. Rest 30-45 min tented loosely with foil. Carving earlier loses 40% of the juice.

The 1-pound rule is close, but not exact

Most sources say 1 lb raw turkey per adult. Real-world yield after cooking and bone is about 50-55%. So 1 lb raw = 8-9 oz cooked meat. For holidays with leftovers, budget 1.25-1.5 lb per person. For a tight dinner with minimal leftovers, 0.8-1.0 lb.

Brining math that actually matters

Wet brine: 1 cup kosher salt + 1 cup sugar + 1 gallon water per 12 lb of bird. Submerge 12-18 hours at 38°F. Dry brine is easier and equally effective: 1 tbsp kosher salt per 4 lb of turkey, rubbed on skin + inside cavity, uncovered on a rack in the fridge for 24-72 hours. Do NOT brine a kosher or pre-basted turkey — they're already salted.

Oven scheduling for multi-dish holidays

A 12-lb turkey takes 3h 15min at 325°F. Pull at breast temp 160°F (rises to 165°F resting). Rest 30-45 min. During rest, crank oven to 425°F for potatoes (50 min) and 375°F for stuffing/casseroles (30 min). Total active oven time: 4 hours, but only one dish at a time after the turkey.

Frequently asked questions

1.How big a turkey for 10 people?

14-16 lb raw for leftovers; 12-14 lb if you have sides galore and don't want leftovers. A 14-lb turkey yields roughly 8 lb of meat after cooking and bone.

2.How long to thaw a frozen turkey?

In fridge: 1 day per 4 lb (so 3-4 days for a 12-14 lb bird). Never thaw on counter — bacteria danger zone. Cold-water thaw: 30 min per lb, changing water every 30 min, only if you must.

3.Should I stuff the cavity?

Food-safety says no — stuffing inside must reach 165°F, by which point the breast is overcooked. Bake stuffing in a separate dish (actually 'dressing'). If you insist, use a probe thermometer in the center of the stuffing.

4.Can I start the turkey the night before?

You can roast it the night before, rest 1 hour, carve, and hold warm meat in a 170°F oven with pan juices. Purists object; it's a sanity-saving hack for big crowds.

5.What temperature should I pull the turkey?

Breast at 160°F, thighs at 175°F. The breast rises 5°F during rest. Pulling at 165°F in the breast = dry turkey. Pro move: probe thermometer stays in while resting so you can monitor carryover.

6.How much turkey per kid?

Count kids under 8 as half an adult portion. A 12-person dinner with 4 kids = 10 adult-equivalents, so 12-14 lb raw.

The pound-per-person math and why it's wrong 80% of the time

Every Thanksgiving article says "1 pound of turkey per person." This is approximately correct and wildly misleading. The real math: 1 pound per adult if you want minimal leftovers, 1.25-1.5 pounds per adult if you want 3 days of leftovers, 0.75 pound per child, zero for vegetarians. A 14-lb bird serves 10 adults comfortably with no leftovers, or 8 adults with sandwiches Saturday. The bone weight is 20% of raw weight — a 12-lb bird gives you 9.6 lb of meat, which after cooking shrinks to about 7 lb edible.

Thaw schedule: the rule every first-timer breaks

Frozen turkey thaws at 4-5 pounds per day in the refrigerator. A 12-lb bird needs 3 full days. A 20-lb bird needs 5. Most home cooks underestimate this and end up with a partially frozen bird on Thursday morning — which forces emergency counter-thawing (USDA says don't) or cold-water thawing (30 min per pound, change water every 30 min). A 16-lb cold-water thaw takes 8 hours of attended work.

Buy frozen turkey by mid-November. Start thawing the Sunday or Monday before Thanksgiving. If you forgot, buy fresh — it costs $2-3/lb more but you gain 3 days of counter time.

Dry brine: the single highest-ROI technique

Dry brining — salting the bird 24-48 hours before roasting — does more for turkey than any other technique. 1 tablespoon kosher salt per 4 pounds, rubbed over the bird, left uncovered on a rack in the fridge. The salt penetrates through osmosis. Moisture draws out, mixes with salt, then re-enters the meat. The result: seasoned meat throughout (not just the surface), drier skin that crisps better, and no sogginess at carving.

Wet brining (submerging in salt water) was the 2005 technique. It's been replaced. Wet brine adds water weight, which dilutes flavor and produces pale, rubbery skin. Dry brining is the 2020+ standard used in every serious test kitchen.

The oven temperature debate, resolved

325°F the whole way is the professional standard for large birds (12+ lb). You get even cooking, crisp skin, and no scary high-heat starts that can overcook the breast. For smaller birds (10 lb or less), 375°F works because the short total time prevents breast over-cooking. The "start at 500°F, drop to 325°F" technique is trendy but adds no real benefit vs. 325°F straight through.

Pull at 160°F in the breast — it rises to 165°F during rest. Thighs should hit 175°F; they handle more heat. Use a probe thermometer from the start; oven timers are unreliable for meat.

Rest time: 30-45 minutes, tented loosely

Every minute you skip resting costs you juice. A turkey carved at 10 minutes loses 40% of its liquid to the cutting board. At 30 minutes, less than 15%. At 45 minutes, almost none. Tent with foil but don't seal — trapped steam makes the skin soggy.

Side math by guest count

Per person, raw weights: 0.5 lb russet potato for mashed, 0.25 lb stuffing, 0.25 cup cranberry sauce, 0.5 cup gravy, 1 dinner roll. These scale linearly. For 8 guests: 4 lb potatoes, 2 lb stuffing base, 2 cups cranberry sauce, 4 cups gravy, 8 rolls. For 16 guests: double everything except cranberry sauce (1½× — people eat less relative to mains at larger gatherings).

When to buy which size

6 guests: 10-lb bird (with leftovers) or 8-lb bird (no leftovers). 10 guests: 14-lb. 14 guests: 18-lb OR two 10-lb birds (two birds cook faster and give you twice the wings). 20+ guests: 20-22 lb OR two 14-lb birds. Commercial kitchens and most top Thanksgiving articles recommend two smaller birds over one giant bird above 20 lb — breast doesn't overcook in the 4-hour roast.

Common failures and their fixes

Dry breast: you roasted too long or pulled too late. Next year, probe thermometer, pull at 160°F.

Bloody thighs: you pulled at 160°F, which is correct for breast but 15°F low for thighs. Either roast longer with foil over breast, or butterfly the bird (spatchcock) so breast and thighs cook at matching rates.

Bland meat: no brine. Dry brine 24 hours before.

Soggy skin: skin was wet when it went in oven. Dry completely with paper towels. Leave uncovered in fridge for 12+ hours before roasting.

Pink meat at 165°F: smoke-ring-style pink from nitrites in the brine, not undercooked. If thermometer reads 165°F, it's done.

Frequently asked

Fresh or frozen? Either works. Frozen gives you more lead time; fresh saves 3 days of fridge space.

Butterball or heritage breed? Heritage tastes better but costs 3-4× more. For 8+ people, Butterball is fine.

Stuff inside or cook stuffing separately? Separately. Stuffing inside a bird has to reach 165°F to be safe — by then the breast is overcooked at 175°F.

Gravy from scratch or jar? Scratch from the pan drippings. Strain, defat, add 2 tbsp flour whisked into 2 tbsp fat, add stock. 10 minutes.

Can I freeze leftover turkey? Yes — 3 months sliced in broth, 2 months dry. Thaw in fridge.
