How it works

Lamb keeps cooking after it leaves the heat. Small chops climb a few degrees; a big leg roast can rise 5 to 10°F while it rests. This calculator tells you when to pull the meat so it lands on the doneness you want, and roughly how long to plan for.

How to use the lamb cooking calculator

Choose the cut and, for roasts, the weight.
Pick your doneness. USDA guidance for whole cuts of lamb is 145°F with a 3-minute rest.
Use the pull temperature with an instant-read thermometer in the thickest part, away from bone.
Rest chops 5 minutes and roasts 15 to 20 minutes, loosely tented with foil.

Frequently asked questions

What temperature should lamb chops be cooked to?

Pull lamb chops at about 130°F for medium-rare; they finish around 135°F after resting. USDA recommends 145°F followed by a 3-minute rest as the minimum safe temperature for whole cuts.

How long do lamb chops take in a pan?

One-inch loin or rib chops take about 3 to 4 minutes per side over medium-high heat for medium-rare. Frenched lollipops take 2 to 3 minutes per side.

How long to roast a leg of lamb per pound?

At 325°F, a bone-in leg needs roughly 20 to 25 minutes per pound for medium-rare and a boneless leg roughly 25 to 30, but always cook to temperature rather than time.
