M&s Smash Burger Recipe

Preparation Steps

1. 1

   Caramelize the Onions

   Heat olive oil in a skillet over medium heat. Add sliced onions, sprinkle with a pinch of salt, and cook, stirring occasionally, until golden brown and caramelized, about 15-20 minutes. Set aside.

2. 2

   Prepare the Burger Patties

   In a bowl, season ground beef with salt and black pepper. Divide the beef into 4 equal portions and shape them into patties, making a slight indentation in the center of each to prevent puffing during cooking.

3. 3

   Cook the Patties

   Preheat a grill or skillet over high heat. Cook the patties for about 3-4 minutes on one side. Flip the patties and place a slice of cheddar and a slice of fontina cheese on top. Cook for another 3-4 minutes, or until the cheese is melted and the burger is cooked to your desired doneness.

4. 4

   Toast the Buns

   While the burgers are cooking, toast the brioche buns on the grill or in a separate skillet until golden brown.

5. 5

   Assemble the Burger

   On the bottom half of each bun, layer lettuce leaves, a slice of tomato, the cooked burger patty with melted cheese, and a generous amount of caramelized onions. Top with the other half of the bun.

6. 6

   Serve

   Serve the burgers hot with your favorite sides.
