Ingredients

Instructions

  1. Step 1: In a large bowl, combine 1 lb ground beef with 1 tsp salt and 1/2 tsp black pepper, mixing gently to combine without overworking. Shape into 8 equal small patties about 2.5 inches in diameter.
  2. Step 2: Heat 1 tbsp olive oil and 2 tbsp unsalted butter in a large skillet over medium heat. Add 2 thinly sliced medium yellow onions and cook, stirring occasionally, for 10 minutes until softened.
  3. Step 3: Pour in 1/2 cup lager beer, reduce heat to low, and simmer onions for another 15 minutes until deeply caramelized and the beer has mostly evaporated, stirring occasionally.
  4. Step 4: Preheat a grill or grill pan to medium-high heat (about 400°F). Grill the 8 patties for 3-4 minutes on each side until medium doneness, placing a slice of cheddar cheese on 4 patties during the last minute to melt.
  5. Step 5: Toast 8 slider buns on the grill for about 1 minute until lightly browned.
  6. Step 6: Assemble sliders by spreading 1 tbsp ketchup and 1 tbsp mustard on each bun bottom, adding a lettuce leaf, a burger patty (cheese optional), and a generous spoonful of beer-caramelized onions. Cover with the bun tops and serve immediately.

How do I store leftover Grilled Burger Sliders with Beer-Infused Caramelized Onions?

Can I substitute ingredients in Grilled Burger Sliders with Beer-Infused Caramelized Onions?
