Whole Chicken Cooking Time Calculator

Estimate roasting time for turkey, chicken, beef, pork, ham and lamb from weight and oven temperature, with USDA safe internal temperatures and rest times.

These figures follow published USDA roasting guidelines, not a measurement of your oven: actual time depends on your oven's true calibration, whether the meat started refrigerator-cold or at room temperature, and the exact cut. Always confirm doneness with a meat thermometer instead of the clock. For converting a recipe's cups and grams, see this site's cooking measurement converter.

This page opens the meat cooking time calculator with whole chicken preselected, using the USDA-guideline rate of about 20 minutes per pound at 325°F (163°C). A whole chicken cooks noticeably slower per pound than a turkey of similar proportions, because it is a much smaller bird relative to its own bone and cavity, and home roasting charts for chicken consistently run higher per-pound minutes than turkey ones.

Enter your chicken's weight and, optionally, switch the oven temperature — many chicken recipes push to 400°F (204°C) for crisper skin, which this calculator's oven-temperature setting accounts for by trimming the total time by roughly 20-25% compared with the 325°F baseline.

The USDA safe internal temperature for whole chicken is 165°F (74°C), checked in the thickest part of the thigh without touching bone. Let it rest 15 to 20 minutes before carving; because a whole chicken is smaller than a turkey, it needs a shorter rest even though the safe temperature is identical.

Accepted Formats & Rules

  • Seven meat profiles with honest per-pound roasting rates at the USDA-standard 325°F (163°C) oven, converted live for kilograms.
  • Doneness choice for beef roast (rare through well done) with the USDA 145°F (63°C) minimum always shown alongside it.
  • Oven-temperature adjustment for 325°F, 350°F and 400°F, safe internal temperature in °F and °C, and a rest-time range.

Key Benefits

✓ Real USDA-guideline roasting rates for seven meats — turkey, whole chicken, chicken breast, beef roast, pork roast, precooked ham and leg of lamb — not one generic "X minutes per pound" rule for everything.
✓ Shows the USDA minimum safe internal temperature and a recommended rest time for the exact meat you picked, so the clock and the food-safety number are never disconnected.
✓ Runs entirely in your browser: pick a weight unit (lb or kg) and oven temperature, get an estimate instantly — no account, no upload.

Use Cases

  • • Work out how long to roast this year's Thanksgiving turkey from its weight, with the USDA-safe 165°F pull temperature and a 20-30 minute rest before carving.
  • • Compare beef roast timing across doneness levels — rare through well done — and see USDA's 145°F minimum safe temperature for whole cuts alongside your chosen doneness.
  • • Figure out how long to reheat a precooked spiral ham without drying it out, using USDA's 140°F reheating target instead of the higher raw-pork temperature.
