These Free Graze Wagyu Beef Burger Patties have a delicious flavor that comes from cows sourced from a long line of Tajima and Akayushi cross-breeds, the same breeds the premium steakhouses use. There are no added hormones, animal by-products or antibiotics in the meat. Cook directly from frozen on a grill or stove top to create the juiciest patty for your next burger or patty melt.
