Juicy smashed beef patties with caramelized onions, melted cheese, and soft buns for a perfect bite.

# What you need:

→ Beef

01 - 1 lb ground beef (80/20 blend)
02 - 0.5 tsp kosher salt
03 - 0.5 tsp freshly ground black pepper

→ Onions

04 - 2 large yellow onions, thinly sliced
05 - 2 tbsp unsalted butter
06 - 1 tbsp olive oil
07 - 0.5 tsp sugar
08 - Pinch of salt

→ Cheese & Buns

09 - 8 slices American cheese
10 - 8 slider buns (mini brioche or potato rolls)

→ Toppings & Condiments

11 - 2 tbsp mayonnaise
12 - 2 tsp yellow mustard
13 - 8 dill pickle slices

# How to make it:

01 - In a large skillet over medium heat, melt butter with olive oil. Add sliced onions, sugar, and salt. Cook, stirring frequently, until onions are soft and golden brown, approximately 20-25 minutes. Set aside.
02 - In a small bowl, whisk together mayonnaise and mustard until combined. Set aside.
03 - Divide ground beef into 8 equal portions of approximately 2 oz each. Form into balls without overworking the meat.
04 - Preheat a large cast-iron skillet or griddle over medium-high heat until very hot.
05 - Place beef balls in the hot skillet, spacing them evenly. Immediately smash each ball flat with a sturdy spatula. Season with salt and pepper. Cook for 1-2 minutes until edges are crispy and browned.
06 - Flip each patty, immediately top with a slice of American cheese, and cook for 1 additional minute until cheese melts completely and patties are cooked through.
07 - Split buns and toast cut-side down in a dry skillet or under a broiler until golden brown.
08 - Spread slider sauce on bottom buns. Layer with cheese-topped patties, generous portions of caramelized onions, and pickle slices if desired. Crown with bun tops. Serve immediately.
