Cooking time calculator

Roasting a chicken, a leg of lamb, a whole salmon side, a pork shoulder? The Cook and Design cooking time calculator gives you a precise minute-by-minute estimate based on weight, cut and desired doneness — the way professional kitchens actually work. We built this tool because the eternal “twenty minutes per pound” rule fails on smaller birds, low-temperature methods and modern convection ovens. Instead, the calculator factors in cut, starting temperature, oven type and target internal temperature to give you a usable range. It also reminds you that every roast needs a rest, and tells you how long to leave it before slicing. The tool is meant as a helpful guide, not a substitute for a meat thermometer (which you should genuinely own). Use it once and you will stop guessing, and your Sunday roasts will become noticeably more reliable. Built by editors who cook, tested by readers, refined every season.
