French Bistro Burgers are topped with ultra creamy melted brie cheese, garlic mayonnaise, caramelized onions, and arugula to bring the gourmet bistro home!
I like to make caramelized onions in the slow cooker: place 4 to 5 large onions, sliced, in a slow cooker with 3 tablespoons butter or olive oil and 1/2 teaspoon salt. Cook on LOW for 10 hours. Refrigerate or freeze the onions.
