Ingredients
Method
Make the Special Sauce
- In a bowl, whisk together mayonnaise, ketchup, yellow mustard, sweet pickle relish, garlic powder, and onion powder. Season with a pinch of salt and pepper. Taste and adjust — the sauce should be tangy and slightly sweet. Refrigerate while you cook so flavors meld.
Form the Patties
- Divide the ground beef into 12 equal balls (about 1.3 ounces each) and gently flatten into thin patties slightly larger than your buns. Salt and pepper both sides.
Cook the Patties
- Heat a large skillet or griddle over medium-high heat until shimmering. Place patties in the pan, listening for that immediate sizzle — it means the crust will form. Cook 1.5 to 2 minutes per side for medium, adding the cheese halves to the patties in the final 30 seconds so it melts.
Toast the Buns
- While patties cook, brush buns lightly with melted butter and toast face-down in another pan or the same skillet until golden.
Assemble the Sliders
- Spread a generous teaspoon of sauce on both the top and bottom bun. Layer bottom bun with a bit of shredded lettuce, a cheesed patty, a pickle slice, and a scattering of chopped onion. Crown with the sauced top bun.
Serve Warm
- Arrange on a platter, tuck napkins nearby, and let everyone help themselves to the comforting mini burgers.
Notes
For a lower-fat version, use 90/10 beef and Greek yogurt mixed with a little mayo in the sauce. If you like heat, add a teaspoon of sriracha to the sauce.
