Quick Scoop

  • Best for deep flavor and juicy, fall-apart meat: shoulder of lamb.
  • Best for a smaller, more elegant roast: lamb rack or rump cap.

What to choose

Leg of lamb is the safest default if you want a roast that looks impressive, carves neatly, and serves a group well. It is widely described as lean, tender, and ideal for larger gatherings.

Shoulder of lamb is the flavor champion if you do not mind a longer cook. Its fat and connective tissue break down during slow roasting, giving you richer, juicier meat.
