Cooking Time Calculator

Slow cookers operate at 190-200°F (88-93°C) on the low setting, far below oven temperatures. As a result, cooking times are approximately 4 times longer than oven roasting. A 3-pound roast that takes 1 hour in the oven takes about 6-8 hours in a slow cooker on low. The extended moist cooking breaks down collagen in tough cuts into gelatin, making slow cookers ideal for brisket, pork shoulder, and lamb shanks.

A pressure cooker (instant pot or stovetop) cooks at about 250°F (121°C) under pressure — significantly higher than boiling water — reducing cooking time to approximately one-third of oven time. A 3-pound roast that takes 60 minutes in the oven takes about 20 minutes under pressure (plus pressurization and depressurization time). Note: pressure cooking does not produce a browned, crispy exterior — sear meat first if desired.

During cooking, muscle fibers contract and push moisture toward the center of the meat. Resting allows the fibers to relax and reabsorb this moisture evenly throughout the cut. Cutting a roast immediately after removing it from heat can lose 40% more juice than one rested for 10-30 minutes. Rest on a cutting board loosely tented with foil to retain warmth.

Yes, but less than commonly assumed. Bringing a 3-pound roast from 38°F (refrigerator) to 70°F (room temperature) takes about 1-2 hours on the counter. The actual reduction in oven time is approximately 10-15 minutes. For large cuts like a whole turkey, the difference is more significant — starting at room temperature reduces cooking time by 20-30 minutes and promotes more even doneness from edge to center.

The USDA recommends an internal temperature of 165°F (74°C) in the thickest part of the thigh, not touching bone. This temperature must be reached in both the breast and thigh. Check multiple spots because temperature varies across large birds. If the breast reaches 165°F before the thigh, tent the breast with foil to slow its cooking while the thigh catches up.

Bone conducts heat faster than muscle tissue — bones are primarily mineral (calcium phosphate) with excellent thermal conductivity. In a bone-in roast, the bone acts as an internal heating element, transferring heat from the center outward while the exterior cooks from outside inward. As a result, bone-in cuts reach target temperature 10-15% faster than boneless cuts of equivalent weight.

The USDA updated pork safety guidelines in 2011 to allow a final internal temperature of 145°F (63°C) with a 3-minute rest for whole cuts (roasts, chops, tenderloin). Ground pork still requires 160°F (71°C). At 145°F, pork will have a slightly pink center — this is safe and produces significantly juicier, more tender results than the previously recommended 160°F.

A stuffed turkey takes 30-45 minutes longer than an unstuffed turkey of the same weight because the stuffing starts cold and must reach a safe internal temperature of 165°F (74°C) at the center of the cavity. This often means the breast meat overcooks before the stuffing is safe. Many food safety authorities recommend cooking stuffing separately for this reason.

Yes — fish is included as a food type. Fish cooks much faster than meat (about 10 minutes per pound for thick fillets). The Canadian fisheries rule of thumb is 10 minutes per inch of thickness at the thickest point, regardless of weight. A 1-inch thick salmon fillet is done in about 10 minutes at 400°F (204°C). The USDA recommends 145°F (63°C) internal temperature, though many chefs prefer 130-135°F (54-57°C) for moist, silky texture.
