Transform leftover prime rib into warm, buttery, toasty sliders with rich au jus for dipping. This easy 30-minute recipe turns holiday leftovers into a cozy, crowd-pleasing meal.

Ingredients

Scale
  • 1 pound leftover prime rib, thinly sliced against the grain
  • 12 slider buns (such as Hawaiian rolls or potato rolls)
  • 6 slices provolone cheese (or Swiss)
  • 4 tablespoons unsalted butter, melted
  • 1 teaspoon garlic powder
  • 1 teaspoon dried oregano or thyme
  • 1/2 teaspoon onion powder
  • 1 packet (1 ounce) dry au jus mix
  • 2 cups water (or beef broth for richer flavor)
  • Optional: horseradish sauce or Dijon mustard for serving

Instructions

  1. Preheat oven to 350°F (175°C).
  2. Slice the cold prime rib thinly against the grain into 1/8 to 1/4 inch thick slices.
  3. In a small saucepan, whisk together the dry au jus mix and 2 cups water (or beef broth). Bring to a boil over medium-high heat, then reduce heat to low and simmer for about 5 minutes, stirring occasionally, until slightly thickened. Keep warm.
  4. In a small bowl, combine melted butter, garlic powder, dried oregano or thyme, and onion powder. Stir well.
  5. Slice the slider buns in half horizontally, keeping tops and bottoms connected if possible. Place bottom halves on a baking sheet.
  6. Layer the sliced prime rib evenly over the bottom buns.
  7. Tear or fold provolone slices to fit over the beef, covering as much as possible.
  8. Place the top buns over the cheese-covered beef, pressing down lightly.
  9. Brush the tops of the rolls generously with the seasoned butter mixture, including the edges.
  10. Cover the baking sheet loosely with aluminum foil and bake for 15 minutes.
  11. Remove the foil and bake for another 5-7 minutes, until tops are golden brown and slightly crispy.
  12. Let the sliders rest on the baking sheet for 2-3 minutes, then cut between the rolls to separate.
  13. Serve immediately with warm au jus for dipping.

Notes

Slice the beef while cold for the thinnest, most even slices. Don’t skip brushing the rolls with seasoned butter—it creates a golden, crispy top. If rolls brown too quickly, cover loosely with foil again. For extra insurance against soggy bottoms, toast the bottom buns for 2-3 minutes before adding beef. Watch the broiler closely if using to brown tops.
