1 stick butter frozen
1 medium Vidalia onion sliced and separated
14 slices American cheese
Salt and pepper
ketchup
2 tbsp Vegetable oil
Buns
(6 Servings)
Prepare flat top griddle or cast iron skillet to high heat. Grate the butter. In a bowl, mix ground beef, grated butter, salt, and pepper thoroughly by hand. Form the meat into 6 or 7 patties. Sprinkle salt and pepper on top of patties. Pour 1 tablespoon vegetable oil on the flat top or on your cast iron griddle and allow to heat up for about 45 seconds. Place onions in oil and sauté about 3 minutes. Next to the onions, add remaining oil and place burgers on hot surface. Cook for about 4 minutes. Flip the burgers and place a slice of American cheese on top of each. Then top with sautéed onions and and another piece of cheese. Cover with a griddle dome and allow to cook 2 minutes. While cheese is melting, place the buns face down on the flat top to get them lightly toasted. Remove the buns from the flat top, place burger onto the bottom bun, top with sautéed onions and ketchup.
