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.
