Cooking Time Rules of Thumb

Turkey: 13-15 min/lb at 350°F unstuffed. Chicken: 18-20 min/lb at 350°F. Beef roast: 15-20 min/lb depending on desired doneness. Pork: 20-25 min/lb at 350°F. Ham: 13-15 min/lb at 325°F. These are estimates — always use a meat thermometer for safety and quality. Internal temperature, not time, determines doneness.

The Rest Period Is Critical

Never skip the rest period after cooking. Resting allows juices to redistribute throughout the meat. Cutting immediately releases juices onto the cutting board, resulting in dry meat. Small cuts: 5-10 minutes. Large roasts: 15-30 minutes. The internal temperature rises 5-10°F during resting (carryover cooking) — remove meat from the oven 5-10°F below your target.

⚡ CalcWolf Insight

Dry-brining (rubbing salt on the turkey 24-48 hours before cooking) produces dramatically juicier meat than wet-brining or no-brining. The salt draws out moisture, dissolves proteins on the surface, and the moisture is reabsorbed — resulting in deeper seasoning and better browning with no soggy skin.

Frequently asked questions
What temperature should turkey be cooked to?
165°F internal temperature in the thickest part of the thigh (not touching bone). The breast reaches 165°F before the thigh — if the breast is done first, shield it with foil while the thigh finishes. Remove the turkey at 160°F — carryover cooking brings it to 165°F during the 15-20 minute rest.
How long to cook a 15-lb turkey?
Unstuffed at 325°F: approximately 3.5-4 hours. Stuffed: 4-4.5 hours. At 350°F unstuffed: 3-3.5 hours. Start checking the internal temperature 30 minutes before the estimated finish time. Every oven is different — the thermometer is your final authority.
