French Bistro Burgers are topped with ultra creamy melted brie cheese, garlic mayonnaise, caramelized onions, and arugula to bring the gourmet bistro home!
Divide the meat into four equal potions. Form each portion loosely into a disk shape, making a deep impression in the center with your thumb. Season both sides of each burger to taste with salt and pepper.
Prepare and preheat a grill, grill pan, or cast iron griddle. Cook the burgers until slightly charred and cooked through, about 5 minutes per side. If using very fresh and high quality ground beef, feel free to cook to medium or medium-rare, about 3 to 4 minutes per side. Remove the burgers from the heat and add the brie cheese. Tent with aluminum foil and allow the burgers to rest for 5 minutes, or until the juices are redistributed and the cheese is melted.
For the garlic mayonnaise:
Combine all the ingredients in a small bowl and refrigerate until ready to use.
To finish:
Top each burger with arugula and caramelized onions. Spread garlic mayo on each burger bun and sandwich the burgers. Serve immediately.
Notes
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.
