Ingredients
  

For the Sliders
  • 6 pieces soft slider buns
  • 1 pound thinly sliced roast beef tender and juicy
  • 1 cup caramelized onions
  • 1 cup shredded or sliced cheese cheddar or provolone (optional)
  • 1 tablespoon melted butter for brushing the tops
For the Au Jus
  • 1 cup au jus store-bought or homemade for dipping

Method
 

Making the Caramelized Onions
  1. Heat a tablespoon of butter or olive oil in a skillet over medium-low heat.
  2. Add thinly sliced onions with a pinch of salt and cook slowly, stirring every few minutes.
  3. Cook until onions are deep amber and jammy, about 25-35 minutes.
Preparing the Au Jus
  1. Heat store-bought au jus according to package instructions, or make your own with beef broth and seasoning.
  2. Keep the au jus warm on the stove for serving.
Assembling the Sliders
  1. Preheat oven to 350°F (175°C) and prepare a baking sheet.
  2. Slice slider buns in half horizontally and lay bottom halves on the baking sheet.
  3. Layer the roast beef evenly on the bun bottoms, followed by the caramelized onions and cheese.
Baking the Sliders
  1. Top with bun tops, brush with melted butter, and bake for 10-15 minutes until golden.
  2. Let rest for 2-3 minutes before serving.
Serving
  1. Serve sliders on a platter with warm au jus for dipping.

Notes

For best results, do not rush the caramelization of the onions and use soft slider buns for better dipping.
