Lamb tenderloins are small portions of meat (each around 3oz) that are the most tender on the entire animal. While tenderloins from larger animals are easily their most prized cuts, lamb tenderloins’ small size & very thin shape make them much less common than racks on restaurant menus.
However, don’t let chefs’ preference for racks sell tenderloins short. These same characteristics make them an extremely quick cooking and perfectly suited to appetizers, light entrees, and salads.
