Big Mac Smash Burger Sliders on Hawaiian Rolls

Why These Big Mac Smash Burger Sliders Work for a Crowd

These party sliders deliver the iconic fast-food flavor profile with seared beef, tangy secret sauce, crisp pickles, and gooey American cheese on warm, sweet rolls. Baking them in whole sheets saves hours at the stove and lets you serve two dozen guests hot finger food simultaneously.

Equipment You Need

• Large flat-top griddle or 12-inch cast-iron skillet
• Stiff metal burger press or wide spatula
• Large rimmed baking sheet (half-sheet pan)
• Serrated bread knife
• Small mixing bowl and pastry brush
• Instant-read meat thermometer

Step-by-Step Directions

1. Whisk the special sauce. Combine the mayonnaise, sweet pickle relish, yellow mustard, white vinegar, smoked paprika, garlic powder, and onion powder in a small bowl until smooth. Cover and chill in the refrigerator until ready to assemble.
2. Preheat the oven and prep rolls. Heat your oven to 350°F. Slice each 12-pack of Hawaiian rolls horizontally across the middle using a serrated knife to create intact top and bottom slabs. Place the bottom halves side-by-side on a rimmed baking sheet.
3. Sear the smash patties. Heat a large cast-iron skillet or flat-top griddle over high heat until smoking. Divide the beef into four 12-ounce portions, press each flat onto the hot steel, season generously with salt and pepper, and sear for 2 to 3 minutes until deep brown crust forms. Flip and cook for another 1 to 2 minutes until beef reaches an internal temperature of 160°F.
4. Layer beef and cheese. Transfer the cooked beef patties onto the bottom rolls, trimming to fit edge-to-edge. Layer the American cheese slices evenly over the hot beef and sprinkle with the finely diced white onion.
5. Bake until cheese melts. Place the top roll slabs over the cheese layer. Brush the tops evenly with melted unsalted butter and sprinkle with toasted sesame seeds. Bake uncovered at 350°F for 8 to 10 minutes, until the roll tops are golden brown and the cheese is fully melted.
6. Add fresh toppings and slice. Carefully lift the warm top bread slabs off the sliders. Spread the chilled special sauce over the melted cheese, scatter the dill pickles and shredded iceberg lettuce across the beef, then replace the tops. Cut along the roll seams into 24 individual sliders and serve immediately.

Host "T-Minus" Prep Timeline

• Day Before: Whisk the special sauce, dice the onions, shred the lettuce, and store each component in airtight containers in the refrigerator.
• T-Minus 2 Hours: Slice the roll slabs horizontally and arrange the bottoms on your baking sheet; cover loosely with plastic wrap to prevent drying out.
• T-Minus 15 Minutes: Smash and sear the beef, assemble the sliders with cheese, brush with butter, and transfer the baking sheet to the oven.

Scaling for Your Party

Plan for 2 sliders per guest for an appetizer spread, or 3 to 4 sliders per guest if serving this as the primary meal. To double the batch to 48 sliders, use two separate half-sheet pans and rotate their rack positions halfway through baking. Brown your beef in batches so the pan stays searing hot and forms proper caramelized crusts.

Substitutions and Dietary Swaps

• Gluten-Free: Swap sweet rolls for certified gluten-free slider buns; bake them directly on parchment as individual portions rather than a single sheet.
• Dairy-Free: Replace the American cheese with meltable plant-based cheddar slices and use melted plant butter on the bun tops.
• Vegetarian: Replace the ground beef with plant-based ground meat, seasoned and smashed using the exact same cook times.
• Sauce Twist: Add 1 teaspoon of hot sauce or sriracha to the burger sauce for guests who enjoy a spicy kick.

Buffet, Storage, and Food Safety

• Room-Temp Shelf Life: Keep hot sliders on the serving table for a maximum of 2 hours per USDA food safety guidelines before discarding or chilling.
• Keep-Warm Tip: Place the baking sheet on a buffet warming mat set to low, or hold the uncut slider sheets in an oven set to 170°F for up to 30 minutes without the lettuce.
• Leftover Storage: Store cooled leftover sliders in an airtight container in the refrigerator for up to 3 days.
• Reheating: Reheat sliders on a baking sheet at 325°F for 6 to 8 minutes until the center reaches 165°F (remove cold lettuce and sauce beforehand if possible for best texture).
