How to Make It

Let’s start creating these delectable sliders!

1. Season the Beef

Combine ground beef, kosher salt, and black pepper in a bowl and mix lightly.

2. Cook the Onions

Melt butter and olive oil in a skillet over medium heat. Add sliced onions, sugar, and a pinch of salt. Cook, stirring occasionally, until the onions are caramelized, about 15 minutes.

3. Form and Cook the Patties

Divide the beef mixture into 8 equal portions. Smash each portion onto a hot griddle or skillet, cooking for about 3 minutes per side for medium doneness.

4. Melt the Cheese

Place a slice of cheese on each patty during the last minute of cooking and cover to melt.

5. Assemble the Sliders

Spread mayonnaise and mustard on the bottom of each slider bun. Add the patty with melted cheese, top with caramelized onions, and finish with a dill pickle slice. Cap with the top bun.

How to Store It

Fridge: Store for up to 3 days in an airtight container.
Freezer: No, the texture will change.
Reheat: Microwave for 30-45 seconds or until heated through.

Tips for Best Results

• Don’t rush the caramelization of onions; let them cook slowly for maximum flavor.
• Use a heavy pan to ensure even cooking of patties.
• If you prefer a crispier bun, toast them lightly before assembly.

Serving Suggestions

• Pair sliders with crispy sweet potato fries.
• Serve alongside a refreshing coleslaw.
• Enjoy with a cold beer or soda for a casual meal.
