Juicy smashed beef patties topped with melted American cheese, caramelized onions, and special sauce, all nestled in soft slider buns — these two-bite burgers are an absolute party showstopper that guests will fight over.

⏱ 50 minServes 6American

Ingredients

  • 1.5 lb lean ground beef (80/20)
  • 12 slider buns or dinner rolls (12-pack, e.g., Hawaiian rolls)
  • 6 American cheese slices, halved
  • 2 yellow onions, thinly sliced
  • 3 tbsp unsalted butter
  • to taste salt and black pepper
  • ¼ cup mayonnaise
  • 2 tbsp ketchup
  • 1 tbsp yellow mustard
  • 1 tbsp sweet pickle relish
  • ¼ tsp garlic powder
  • as needed dill pickle chips and shredded iceberg lettuce, for serving

Directions

  1. 1Make the special sauce by whisking mayonnaise, ketchup, mustard, relish, and garlic powder together; refrigerate until needed.
  2. 2Melt 2 tbsp butter in a large cast-iron or heavy skillet over medium-low heat; add onions with a pinch of salt and cook, stirring occasionally, 20–25 minutes until deeply golden and caramelized.
  3. 3Divide ground beef into 12 equal balls (about 55 g each) and season generously with salt and pepper.
  4. 4Wipe out the skillet, raise heat to medium-high, and add remaining butter; working in batches, place beef balls in the pan and smash flat with a spatula, pressing firmly for 10 seconds.
  5. 5Cook smashed patties 2 minutes until edges are brown and crispy, then flip, immediately top each with a half slice of cheese, and cook 1 minute more.
  6. 6Split slider buns and toast the cut sides in the same pan for 1 minute until lightly golden.
  7. 7Spread special sauce on both bun halves, place a cheesy patty on each bottom bun, and top with a small pinch of caramelized onion, a pickle chip, and a tuft of shredded lettuce.
  8. 8Cap with the top buns and serve immediately on a platter.

💡 The smash-and-sear technique gives you crispy, lacy edges and is the reason these sliders taste restaurant-quality. Hawaiian rolls (sold in 12-packs at most Canadian grocery stores) are the ideal bun — soft, slightly sweet, and the perfect size.
