The way to make sliders for a crowd is to stop making them one at a time. Press the ground beef into a single thin slab on a sheet pan, bake it, cut it into squares, and lay it across a whole tray of split slider rolls at once. Twenty-four sliders come out of the oven together, every patty the same size, and the only knife work left is the toppings, which you prep on a board an hour before anyone arrives.

Sliders turn up on every game-day and party list because they are a full burger in three bites, eaten standing up. They are also the dish most likely to keep a host at the stove for an hour, flipping two dozen tiny patties in batches. The sheet-pan method fixes that.

What to buy for 24 sliders

  • 2 1/2 pounds ground beef, 80/20 (lean to fat)
  • 24 slider rolls, sold as a connected slab (soft potato rolls or sweet Hawaiian-style rolls both work)
  • 12 slices American or cheddar cheese
  • 1 yellow onion
  • Salt, pepper, garlic powder, Worcestershire sauce
  • 4 tablespoons butter, melted, with a teaspoon of sesame seeds for the tops

Use 80/20 beef. Leaner beef dries out in the oven; the fat keeps a thin slab juicy. Plan two to three sliders per adult if there are other dishes on the table, four if sliders are the main event.

The sheet-pan patty

Heat the oven to 400°F and line a half-sheet pan (13 × 18 inches) with parchment. Mix the beef with two teaspoons of salt, one teaspoon of pepper, one teaspoon of garlic powder and a tablespoon of Worcestershire, using your hands and stopping as soon as it is combined; overworked beef bakes tough.

Press the meat into an even layer covering about two thirds of the pan, the same footprint as your slab of rolls. A second sheet of parchment on top and a flat-bottomed glass make it even. Bake for 15 to 18 minutes.

Ground beef has to reach 160°F to be safe, the USDA minimum for ground beef, and color is not a reliable guide; ground beef can brown before it gets there. Check the thickest part with an instant-read thermometer, inserting it sideways into the thin slab. Pour off the fat, then lay the cheese across the top and return it to the oven for two minutes to melt.

Building the tray

While the beef bakes, split the whole slab of rolls horizontally with a long serrated knife, keeping the tops and bottoms in one piece each. Set the bottom half in a 9 × 13 baking dish or on a second sheet pan.

Lift the cheese-topped slab onto the bottom buns with two wide spatulas. Add the toppings that go inside and warm, such as caramelized onions or pickles, put the top slab of rolls on, and brush it with the melted butter.

Scatter the sesame seeds. Bake for five more minutes, until the tops are golden. Cut between the rolls with a sharp knife to separate the sliders.

The topping board

The cold toppings are what make sliders feel like a spread and not a casserole. Set them out on a board beside the tray and let people dress their own.

  • Pickles. Dill pickle chips, drained and patted dry.
  • Onion. One red onion, shaved paper-thin into rings. Soak them in ice water for ten minutes to take off the sharpness.
  • Tomatoes. Two Roma tomatoes, sliced thin. Cut them last, right before serving.
  • Lettuce. A few leaves of iceberg or green leaf, shredded or torn to bun size.
  • Jalapeños, sliced into rings, for heat.
  • Sauces, in small bowls at the edge: ketchup, mustard, mayonnaise, and a burger sauce of mayonnaise, ketchup and chopped pickle.

Prep these on the board in the right order: lettuce and onion first, then pickles, then tomatoes last. Keep raw beef off the board entirely by mixing it in a bowl and pressing it straight into the pan. If the board did touch raw meat, wash it with hot soapy water before the vegetables go on it; how to clean a cutting board after raw meat covers the full routine.

Variations

The same method works for any slider. Swap the beef for ground turkey, which needs to reach 165°F, and add a little more seasoning since turkey is milder. For pulled pork sliders, skip the slab and pile warm shredded pork on the bottom buns with coleslaw. For a vegetarian tray, bake portobello caps or thick slices of halloumi and cut them to size.

Sliders are one dish among several on a game-day table. A tray of gochujang wings bakes in the same oven while the beef rests, and rounds out the table without adding to the work.

Make-ahead timeline

The night before: shave the onion and store it in water; mix the burger sauce.

Two hours before: season and press the beef into the pan, cover and refrigerate.

One hour before: prep the topping board.

Thirty minutes before: bake the slab, build the tray, bake again, and cut. Bring it out hot and set the board beside it. Cooked burgers and cut toppings are good on the table for two hours; after that, bring out a fresh tray rather than leaving the first one sitting.
