June’s homage to a West Coast favorite--In-N-Out Burger’s Animal-Style Cheeseburger starts with patties brushed in mustard, just like the original. We include extra pickles and extra sauce along with grilled onions, lettuce and tomato, and we even respect the stack order of In-N-Out’s famous burgers for an authentic experience you don’t have to be on the West Coast to enjoy! Make sure your dinner rolls are the kind that are connected in a slab, and the bigger the better--ideally they’ll be the size of the June Pan. A 12-count slab will work but, depending on the brand, you may need to trim the sides of the cooked patty. We found King’s Hawaiian Party Pack of 24 work the best. If you have a batch of June's Caramelized Onions you can use them here--you only need 1 cup chopped. If prepping for a party, the sauce and onions can be made in advance, then cook the meat and assemble the sliders when you’re ready to serve.
