Juicy burgers topped with Thousand Island Dressing, melted cheese and sourdough bread grilled to perfection make these Frisco Burgers a family favorite!
Divide ground beef, and shape into ovals or rectangles based on the shape of your bread.
Sprinkle with salt and pepper, and cook in a large skillet.
When second side of burger is almost cooked through, place cheese slices on top of each patty and allow to melt.
Butter one side of each slice of sourdough bread.
Sprinkle with grated Parmesan, and place in a different skillet. Cook until golden brown. The cheese might stick to the bottom, don't worry.
Spread thousand island dressing on the non-grilled side of the sourdough bread, and place cheeseburger patty on top.
Top each burger with lettuce, tomato and onion slices. Place second slice of sourdough on top.
Serve with fries, potato wedges, or green salad.
Notes
To make grilled onions, slice onions thinly and cook them in a skillet with a bit of olive oil over medium heat until they are caramelized and golden brown.
