Bacon Burgers On Brioche Buns

1. 1

   Preheat the oven to 400u00b0. On a rimmed baking sheet, toss the onions with 2 tablespoons of the olive oil and roast until softened, about 20 minutes.

2. 2

   Meanwhile, in a small bowl, whisk the mayonnaise with the lemon juice. Gradually whisk in the remaining 1/4 cup of olive oil and season with salt and pepper.

3. 3

   In a large skillet, cook the bacon over moderately high heat until crisp. Drain on paper towels and break each strip in half.

4. 4

   Light a grill or preheat a grill pan. Form the ground meat into eight patties. Season generously with salt and pepper and brush with olive oil. Grill over moderately high heat until well-browned on the bottom, 5 minutes. Flip the burgers, mound the brie on top and grill for 4 minutes longer, until the cheese is slightly melted and the burgers are medium-rare.

5. 5

   Spread the lemon mayonnaise on the cut sides of the buns; set the burgers on the bottoms and top with the bacon and onions. Close the burgers and serve right away.
