Toppings, optional: caramelized onions, ketchup, lettuce, and the like
Instructions
If you would like to caramelize onions, thinly slice two onions and cook, covered, over medium-low to low heat in two tablespoons of neutral oil until melted and caramel brown, about 45 minutes. TIP: See our French Onion Soup recipe for complete instructions for making true caramelized onions.
Divide the meat into 6 equal portions, then divide each portion in half again. Flatten the beef portions into thin patties. Take half of the gorgonzola and place about 1 tablespoon of gorgonzola in the center of 6 patties. Make sure the cheese is broken into pieces and fairly flat, not mounded.
Top the blue cheese patties with another patty. Gently press allover to seal the patties together and flatten into one burger. Season both sides with salt.
Grill or broil, topping with cheese in the final minute of cooking. To broil: Preheat the broiler and place the rack about 4 inches from the element. Broil the burgers on a greased, foil-lined sheet pan for 2 to 3 minutes per side, turning once. Top with more cheese in the final minute of cooking.
Put each burger on a bun, top with desired fixin's, and serve.
