In a bowl, combine the ground beef with salt and black pepper, then shape into 4 equal-sized patties.
In a hot skillet or on a grill, cook the patties for 3-4 minutes on one side, then flip.
After flipping, place a slice of brie cheese on each patty, then cover the skillet to allow the cheese to melt.
Halve the hamburger buns and spread butter on the cut sides. Toast in a skillet until golden brown.
Spread Dijon mustard and mayonnaise on the bottom half of each bun, then top with a handful of arugula.
Place the brie-topped patty on the arugula, then pile on the caramelized onions.
Drizzle a little olive oil on the top half of each bun, then place it on the burger.
Serve immediately with french fries or a side salad.
