Ingredients

Slider

  • 12 slices havarti cheese
  • 12 slices sharp cheddar cheese
  • 12 slices mozzarella cheese
  • 12 sweet Hawaiian slider buns
  • ½ large sweet onion sliced
  • salt and pepper to taste
  • oil for pan

Sauce

  • 4 tbsp butter melted
  • 2 tsp garlic aioli mustard
  • ½ tbsp white sesame seeds

Instructions

  • Preheat oven to 350°
  • Heat a drizzle of oil in a medium sized skillet, over medium low heat.
  • Thinly slice onion and add to pan. Sprinkle with a pinch of salt and pepper. Cook the onions over medium low heat, stirring occasionally until the onions are soft and lightly browned. Set aside.
  • Open the slider buns and place the bottoms into a prepared baking dish.
  • Begin layering the cheese, one kind at a time, being careful to ensure that it is evenly spread over the buns.
  • Top with caramelized onions.
  • Place tops of buns onto the sliders and press down lightly.
  • Melt the butter in a small bowl, then combine with garlic aioli.
  • Spread the melted butter over the buns, being careful to cover each one evenly. Sprinkle with sesame seeds.
  • Cover with foil, and place in oven for 15 minutes or until cheese is completely melted. If desired, you can remove the foil for the last five minutes of baking to toast the tops of the buns.
  • Serve warm.
