Beef Sliders Caramelized Onions Cheese (Print Version)

Juicy beef sliders topped with caramelized onions and melted cheese on soft slider buns.

# What You Need:

→ Beef Patties

01 - 1.1 lb ground beef (80/20 blend recommended)
02 - 1 tsp kosher salt
03 - ½ tsp freshly ground black pepper
04 - ½ tsp garlic powder

→ Caramelized Onions

05 - 2 large yellow onions, thinly sliced
06 - 2 tbsp unsalted butter
07 - 1 tbsp olive oil
08 - ½ tsp sugar
09 - ¼ tsp salt

→ Cheese and Assembly

10 - 8 slices cheddar cheese (or Swiss, provolone, or American cheese)
11 - 8 slider buns
12 - 2 tbsp mayonnaise (optional)
13 - 1 tbsp Dijon mustard (optional)
14 - Lettuce leaves, tomato slices, or pickles (optional)

# How To Make:

01 - In a large skillet over medium heat, melt butter with olive oil. Add sliced onions, salt, and sugar. Cook, stirring occasionally, for 20–25 minutes until onions are deep golden brown and fully caramelized. Lower heat as needed to prevent burning. Set aside.
02 - In a bowl, gently mix ground beef with salt, pepper, and garlic powder. Divide into 8 equal portions and shape into small, slightly larger-than-bun patties (they will shrink as they cook). Heat a grill pan or skillet over medium-high heat. Cook patties for 2–3 minutes per side for medium, or to desired doneness.
03 - During the last minute of cooking, place a slice of cheese on each patty. Cover pan to melt cheese.
04 - Lightly butter and toast slider buns, cut sides down, in a skillet or on a griddle until golden.
05 - Spread mayonnaise and/or Dijon mustard on the bottom bun, if desired. Place the beef patty with melted cheese on the bun. Top with a generous spoonful of caramelized onions. Add lettuce, tomato, or pickles if using, then cover with top bun. Serve immediately.
