If you like your lamb chops cooked to medium-rare (as I do), you’ll grill them just long enough to get a good sear on the outside and stay juicy within. Grilling 3 to 4 minutes per side over medium-high heat on a charcoal or gas outdoor grill is just right. To check for the correct internal temperature, an instant read thermometer or meat thermometer should read 135°F when inserted in the thickest part. Let chops rest 5 minutes before serving.
