Ingredients

Scale

Caramelized Onions

  • 3 tablespoons unsalted butter
  • 1 medium onion, thinly sliced
  • 2 teaspoons fresh thyme, minced
  • ¼ teaspoon kosher salt
  • ¼ teaspoon black pepper

Sliders

  • 12 sweet rolls
  • 10 slices provolone cheese
  • 14 ounces sliced deli roast beef

Butter Onion Topping

  • ½ cup unsalted butter, melted
  • 1 ½ tablespoons dried onion soup mix

Au Jus

  • 1 packet au jus gravy mix
  • 3 cups water

Optional Garnish

  • Fresh chopped parsley

Instructions

  1. Caramelize the Onions: In a large skillet over medium heat, melt 3 tablespoons of unsalted butter. Add the thinly sliced onion and coat them well with butter. Cook, stirring occasionally, for about 12-15 minutes until the onions are soft, browned, and caramelized but not burnt.
  2. Season the Onions: Once the onions are caramelized, add minced fresh thyme, kosher salt, and black pepper to the skillet. Stir well to combine all flavors, then remove from heat and set aside.
  3. Prepare the Rolls: Preheat the oven to 350°F (175°C). Take the 12 sweet rolls out of their package, keeping them intact. Using a large knife, slice through the rolls horizontally to separate the tops from the bottoms. Arrange the bottoms, cut side up, in an 11×7-inch baking dish.
  4. Assemble the Sliders: Layer half of the provolone cheese slices on top of the bottom rolls. Add the sliced deli roast beef evenly over the cheese, then spread the prepared caramelized onions on top of the beef. Finish with the remaining provolone slices, and place the roll tops over everything.
  5. Brush with Butter Onion Mixture: In a small bowl, combine melted butter with the dried onion soup mix. Use a brush to evenly coat the tops of the rolls with this flavorful mixture. This will add a savory, golden glaze during baking.
  6. Bake the Sliders: Cover the baking dish loosely with foil, ensuring the foil does not touch the tops of the rolls. Bake for 25 minutes, then remove the foil and bake for an additional 5 minutes to brown the tops to a golden finish.
  7. Prepare Au Jus: While the sliders bake, prepare the au jus gravy as per the packet instructions by mixing the au jus gravy mix with 3 cups of water and heating until ready.
  8. Serve: Remove the sliders from the oven, garnish with fresh chopped parsley if desired, and serve warm with the au jus on the side for dipping.

Notes

  • Make sure to cook the onions slowly to avoid burning and develop a deep caramelized flavor.
  • If you prefer a less sweet roll, you can substitute with regular dinner rolls.
  • The onion soup mix in the butter topping helps create a flavorful crust and adds an umami punch.
  • Au jus can be made from scratch or substituted with store-bought beef broth seasoned with soy sauce and Worcestershire sauce.
  • For extra flavor, add a few dashes of Worcestershire sauce to the roast beef before assembling.
