🥗 Ingredients
The Beef & Buns
- 1.5 pounds Ground Beef (80/20 lean-to-fat ratio, chilled)
- 12 pieces Slider Buns (Brioche or potato rolls, connected in a pack)
- 3 tablespoons Unsalted Butter (melted)
The Aromatics & Cheese
- 2 Yellow Onion (sliced paper-thin using a mandoline)
- 6-8 slices American Cheese (high-quality deli style)
- 1 teaspoon Kosher Salt (plus more to taste)
- 1/2 teaspoon Black Pepper (freshly cracked)
Secret Tavern Sauce
- 1/2 cup Mayonnaise (full fat)
- 1 tablespoon Yellow Mustard
- 1 tablespoon Ketchup
- 2 teaspoons Dill Pickle Juice
- 1/4 teaspoon Smoked Paprika
Garnish
- 24 pieces Dill Pickle Chips (crinkle cut)
👨🍳 Instructions
-
1
Prepare the beef by portioning the chilled ground meat into 12 equal-sized balls (about 2 ounces each). Do not overwork the meat; keep it loose for a tender texture.
-
2
Whisk together the mayonnaise, mustard, ketchup, pickle juice, and smoked paprika in a small bowl. Set the secret sauce aside in the refrigerator to let flavors meld.
-
3
Using a long serrated knife, slice the entire pack of slider rolls in half horizontally, keeping the individual rolls connected. This creates one large top slab and one large bottom slab.
-
4
Brush the cut sides of the buns with half of the melted butter. Place them face down on a large griddle or cast-iron skillet over medium heat for 1-2 minutes until golden brown and toasted.
-
5
Increase the heat to medium-high. Add a small splash of oil to the skillet and spread the paper-thin onions across the surface. Sauté for 3-4 minutes until they begin to soften and turn translucent.
-
6
Push the onions into 12 small mounds in the skillet. Place one beef ball directly on top of each onion mound.
-
7
Using a heavy spatula (and a second tool for leverage), smash each beef ball down firmly onto the onions until they are thin, flat patties. Season generously with salt and pepper.
-
8
Cook undisturbed for 3 minutes. The onions underneath will caramelize and fuse into the meat while the beef develops a dark, crispy crust.
-
9
Carefully flip each patty, ensuring the onions stay attached to the meat. Immediately top each patty with a square of American cheese.
-
10
Place the bottom 'slab' of buns directly on top of the cheesy patties in the skillet. Place the top 'slab' of buns over the bottom ones. Cover the skillet with a lid for 60 seconds to allow the steam from the onions to soften the buns.
-
11
Remove the lid. Use a large spatula to lift the patties out and place them onto the bottom buns. If they are still connected, you can lift them in groups.
-
12
Spread a generous layer of the secret sauce on the underside of the top bun slab and place it over the patties.
-
13
Garnish by placing two pickle chips on each individual slider. Use a knife to cut through the buns and separate them into 12 individual sliders.
💡 Chef's Tips
For the best crust, ensure your cast-iron skillet is preheated until it's smoking slightly before adding the meat. Don't skip the onion-steaming step; it's the secret to that authentic 'White Castle' or 'Slider' texture and aroma. Use 80/20 ground beef; anything leaner will result in a dry slider that lacks the necessary flavor. If you don't have a heavy spatula, use a small piece of parchment paper between the meat and a flat-bottomed bowl to smash the patties. Keep the meat cold until the very moment it hits the pan to ensure the fat doesn't melt prematurely.
🍽️ Serving Suggestions
Serve with a side of crispy, thin-cut shoestring fries seasoned with truffle salt. Pair with a cold, hoppy IPA or a classic root beer float for a nostalgic feel. A side of creamy coleslaw provides a refreshing, crunchy contrast to the soft sliders. Offer extra dipping sauce on the side for those who love a messy, flavor-packed burger. Serve on a large wooden board for a communal, party-friendly presentation.
