Yes! You can cook this lamb appetizer ahead of time (up to an hour) and keep them warm in a very low oven. u003cstrongu003eJust make sure to undercook them a bit as they will continue to cook in a warm oven.u003c/strongu003eu003cbr/u003eu003cbr/u003eI'd suggest sautéing them on a slightly higher heat to brown the outside and cooking them to an internal temperature of 138º-140ºF (rare). Then they can rest in the warm oven while the party gets started!
