Ingredients
  

Sliders
  • 1 package Hawaiian or dinner slider rolls Split into tops and bottoms.
  • 1 lb deli roast beef Thinly sliced.
  • 12 slice provolone cheese Sliced for layering.
For the au jus
  • 2 cup beef broth
  • 2 tbsp Worcestershire sauce
  • 1 tbsp soy sauce
  • 1 tsp garlic powder
  • 0.5 tsp onion powder
For the butter topping
  • 4 tbsp butter Melted.
  • 1 tbsp Dijon mustard
  • 1 tbsp Worcestershire sauce
  • 1 tsp garlic powder
  • 1 tbsp fresh parsley, chopped

Equipment

  • 1 sheet pan
  • 1 saucepan
  • 1 9x13 baking dish

Method
 

Make the au jus
  1. Preheat the oven to 350°F, then in a saucepan simmer the beef broth, Worcestershire sauce, soy sauce, garlic powder, and onion powder for 10 minutes over medium heat, stirring until combined.
  2. Keep the au jus warm on the lowest heat setting while you assemble the sliders.
Assemble the sliders
  1. Place the slider roll bottoms in a greased 9x13 baking dish and layer the deli roast beef and provolone cheese over the rolls, then place the tops back on.
  2. Whisk together the melted butter, Dijon mustard, Worcestershire sauce, garlic powder, and fresh parsley, then brush generously over the tops of all the sliders.
  3. Cover the sliders with foil and bake for 15 minutes at 350°F until heated through.
  4. Remove the foil and bake for 5 minutes at 350°F until the tops are golden and the provolone cheese is fully melted.
  5. Slice the baked sliders into individual sandwiches and serve immediately with small cups of warm au jus for dipping.

Notes

Pro tip: keep the au jus covered and warm so it stays easy to dip; if it thickens, loosen with a splash of beef broth. Refrigerate leftovers in a sealed container for up to 3 days; reheat covered at 325°F until warmed through. Freezing is not recommended because slider rolls and deli roast beef texture change after thawing. For a dairy-light option, use provolone-style lactose-free cheese to reduce dairy while keeping the melty finish.
