Beef Marinade. Marinating is best suited for the tougher steak cuts like flank, skirt, sirloin, round and hanger. These cuts can usually marinate up to 24 hours. You can actually ruin better-quality steaks, like porterhouse or rib-eye, by marinating them.
A lot of skirt steak recipes call for marinating the meat before grilling it, and because of its looser structure, skirt steak will absorb the flavors of the marinade quite well. But there's no need to marinate it for more than 30 minutes or so, as marinating does not tenderize meat.
