🥗 Ingredients
The Beef Patties
- 1.5 pounds Ground Chuck (80/20 fat ratio for maximum juiciness)
- 1 tablespoon Worcestershire Sauce
- 1 teaspoon Garlic Powder
- 1 teaspoon Kosher Salt (plus more for seasoning)
- 1/2 teaspoon Black Pepper (freshly cracked)
Caramelized Onions
- 2 large Yellow Onions (thinly sliced into half-moons)
- 2 tablespoons Unsalted Butter
- 1 tablespoon Balsamic Vinegar (high quality)
- 1 teaspoon Brown Sugar (optional, to aid caramelization)
Assembly & Sauce
- 12 pieces Brioche Slider Buns (split and lightly toasted)
- 6 slices Gruyère Cheese (cut into quarters to fit sliders)
- 1/4 cup Mayonnaise
- 1 tablespoon Dijon Mustard
- 1 cup Arugula (baby leaves, washed and dried)
- 12 slices Pickle Chips (dill flavor)
👨🍳 Instructions
-
1
Start with the onions: Melt 2 tablespoons of butter in a large skillet over medium-low heat. Add the sliced onions and a pinch of salt.
-
2
Cook the onions slowly, stirring occasionally, for about 20-25 minutes until they are deep golden brown and soft. If they look dry, add a splash of water.
-
3
Once onions are caramelized, stir in the balsamic vinegar and brown sugar. Cook for another 2 minutes until glazed, then remove from heat and set aside.
-
4
In a large mixing bowl, gently combine the ground chuck, Worcestershire sauce, garlic powder, salt, and pepper. Do not overwork the meat, as this makes the sliders tough.
-
5
Portion the meat into 12 equal balls (about 2 ounces each). Flatten them into patties slightly wider than your buns, as they will shrink during cooking.
-
6
Using your thumb, make a small indentation in the center of each patty. This prevents them from bulging into 'footballs' while searing.
-
7
Whisk together the mayonnaise and Dijon mustard in a small bowl to create the signature slider sauce.
-
8
Heat a large cast-iron skillet or griddle over medium-high heat. Lightly toast the cut sides of the brioche buns until golden, then set aside.
-
9
Increase heat to high and add the patties to the skillet. Sear for 2-3 minutes until a dark, crusty char forms on the bottom.
-
10
Flip the patties. Immediately place a piece of Gruyère cheese on each patty. Pour a teaspoon of water into the pan and cover with a lid for 30 seconds to melt the cheese perfectly.
-
11
Remove patties from the heat and let them rest for 2 minutes—this is crucial for retaining the juices.
-
12
Assemble: Spread the bottom bun with the Dijon-mayo, add a few leaves of baby arugula, then the beef patty with melted cheese.
-
13
Top the cheese with a generous spoonful of caramelized onions and a pickle chip. Close with the top bun and serve immediately.
💡 Chef's Tips
Always use 80/20 ground chuck; leaner meat will result in dry, crumbly sliders. Avoid over-mixing the beef; handle it just enough to form the shape to keep the texture light and tender. Make sure your skillet is screaming hot before adding the beef to get that essential Maillard reaction crust. If you can't find Gruyère, Emmental or a sharp white cheddar are excellent melting substitutes. For a crowd, you can bake the sliders in a 9x13 dish: slice the whole pack of buns in half horizontally, layer ingredients, and bake at 350°F for 10 minutes.
🍽️ Serving Suggestions
Pair with a crisp, hoppy IPA or a chilled glass of dry Amber Ale to cut through the richness. Serve alongside truffle parmesan fries or sweet potato wedges for a complete gastropub experience. A side of tangy vinegar-based coleslaw provides a refreshing crunch that balances the savory beef. For a non-alcoholic pairing, try a sparkling apple cider or a ginger beer with a squeeze of lime.
