How to Use This Converter
Cook times are calculated as minutes-per-pound based on USDA guidelines and common culinary standards. These are estimates — always verify with a meat thermometer.
- Times are for oven cooking unless noted as "low & slow."
- Resting time is critical — the meat continues cooking 5–10°F after you remove it.
- Large cuts (brisket, pork shoulder) have more variance — check internal temp.
- Bone-in cuts take longer than boneless by ~20%.
Examples
3 lb beef roast (medium rare)
→ ~51 min at 325°F + 15 min rest
5 lb whole chicken
→ ~1 hr 40 min at 375°F + 10 min rest
12 lb turkey (unstuffed)
→ ~3 hrs at 325°F + 20 min rest
8 lb pork shoulder (low & slow)
→ ~12 hrs at 225°F + 30 min rest
Frequently Asked Questions
How accurate are these cook times?
These are general estimates. Actual times vary based on oven calibration, shape of the cut, starting temperature, and altitude. Always use a meat thermometer to confirm doneness.
Should I cook from frozen?
No — always thaw meat fully in the refrigerator before cooking. Frozen meat takes 50% longer and may not cook evenly.
Why is resting time important?
Resting lets the juices redistribute throughout the meat. Cut too early and the juices run out onto the cutting board, leaving the meat dry.
