Step 1

Mix 2 Tablespoons of the butter into the ground beef.

Step 2

Divide the beef into 4 even patties. Season with the salt and pepper.  Refrigerate for at least 30 minutes.

Step 3

Melt 2 tablespoons of butter in a large skillet over medium high heat.  Add the chopped onions to the skillet and sauté until tender (approximately 5-7 minutes). Reduce the heat on the skillet to look and cook for 3-4 minutes until browned.

Step 4

Transfer the onions to a separate plate.

Step 5

Place the patties into the skillet and cook for 4-6 minutes without moving the patties.

Step 6

Flip the patties and cook on the other side for 4-6 more minutes until the patties are cooked through.

Step 7

Turn off the heat, top each patty immediately with 1 tablespoon of butter each, ¼ of the sautéd onions and a slice of the cheese. The heat from the pattes should melt the butter and the cheese.

Step 8

Remove from the skillet and place on the toasted buns.

Step 9

Serve immediately while warm and enjoy!
