Instructions

  1. Step 1: Thinly slice 1 medium yellow onion. In a skillet over medium heat, melt 2 tbsp unsalted butter and add the onions. Cook slowly for 15-20 minutes until golden brown and caramelized, stirring occasionally.
  2. Step 2: In a bowl, combine 1 lb ground beef with 1 tsp chipotle chili powder, 1 tsp salt, and 1/2 tsp black pepper. Mix gently to combine without overworking the meat.
  3. Step 3: Heat 2 tbsp vegetable oil in a cast-iron skillet over high heat until shimmering. Divide beef into 4 equal portions.
  4. Step 4: Place one portion in the skillet and smash it down firmly with a spatula until about 1/2-inch thick. Cook for 2-3 minutes until the edges are crispy and browned.
  5. Step 5: Flip the patty, place 1 slice cheddar cheese on top, and cook for another 1-2 minutes until cheese melts and burger is cooked through.
  6. Step 6: Toast 4 burger buns lightly in the skillet or toaster.
  7. Step 7: Mix 1/4 cup mayonnaise with 1 tsp lime juice and spread on each bun base.
  8. Step 8: Assemble burgers by placing the patty with melted cheese on the bun, topping with a generous spoonful of caramelized onions, and finishing with the bun top.
