Beef Sliders Caramelized Onions

I still remember the first time I tried making beef sliders with caramelized onions; the moment the sweet aroma filled my kitchen, I knew this little recipe was going to be a staple for every casual get-together.

Once, when unexpected guests dropped by, I whipped these up on a whim and nailed the caramelized onions just right; the compliments haven't stopped since!

Ingredients

• Ground beef (80/20 blend): I always go for this ratio to keep the sliders juicy without too much grease
• Yellow onions: Thin slices caramelize beautifully and bring a wonderful sweetness
• Kosher salt: A little goes a long way in seasoning perfectly
• Cheddar cheese: Adds a creamy melt that pairs perfectly with the beef
• Slider buns: Choose soft, fresh buns that can hold the toppings without falling apart

Instructions

Get Everything Ready:

Gather all your ingredients and tools so you can glide through this recipe without interruptions.

Caramelize the onions:

Heat butter and olive oil gently and add the onions and salt. Stir occasionally and watch as the onions turn a gorgeous golden brown, filling your kitchen with sweetness over 20 to 25 minutes.

Season and shape the patties:

Mix ground beef with salt, pepper, and Worcestershire sauce. Divide into eight equal parts and gently shape to be just a bit bigger than your buns.

Cook the sliders:

On a hot grill or skillet, cook patties 2 to 3 minutes on each side until perfect. Add cheese in the last minute to get that melty finish.

Toast the buns and assemble:

Give your buns a quick toast for texture. Spread mayo and mustard, then pile on lettuce, beef, caramelized onions, tomato, and pickles before topping with the bun.
