No Grill, No Problem. Carne Asada makes a quick, delicious dinner anytime and doesn’t require a grill. Just heat a large cast iron skillet over medium-high heat until very hot. Add a little oil and when it is piping hot add the Carne Asada. Sear on each side for about 3 minutes to medium-rare. Remove from the pan and place on a cutting board loosely covered with foil. Allow to rest at least 5 minutes and then slice against the grain for maximum tenderness.
