Ingredients Method Notes

Ingredients
  

  • 3 tablespoons unsalted butter
  • 1 medium onion thinly sliced
  • 2 teaspoons fresh thyme minced
  • 1/4 teaspoon kosher salt
  • 1/4 teaspoon black pepper
  • 12 sweet rolls (such as King’s Hawaiian)
  • 10 slices provolone cheese
  • 14 ounces sliced deli roast beef
  • 1/2 cup unsalted butter melted
  • 1 1/2 tablespoons dried onion soup mix
  • 1 packet au jus gravy mix
  • 3 cups water
  • Fresh chopped parsley for garnish (optional)

Method
 

  1. In a large skillet over medium heat, melt 3 tablespoons of butter. Add the sliced onions and coat them thoroughly in the butter. Cook, stirring occasionally, for about 12-15 minutes until the onions are soft and browned, being careful not to burn them.
    3 tablespoons unsalted butter, 1 medium onion
  2. Add the minced thyme, salt, and pepper to the skillet. Stir to combine, then remove the pan from the heat and set aside.
    2 teaspoons fresh thyme, 1/4 teaspoon kosher salt, 1/4 teaspoon black pepper
  3. Preheat your oven to 350°F. Remove the rolls from the package, keeping them intact. Use a large serrated knife to slice the entire block of rolls in half horizontally so you have a top and a bottom section. Place the bottom half, cut side up, into an 11x7-inch baking dish.

  4. Layer half of the provolone cheese slices over the bottom rolls. Add the roast beef in an even layer, then spread the caramelized onions over the meat. Top with the remaining cheese slices and place the top half of the rolls back on.

  5. In a small bowl, whisk together the melted 1/2 cup of butter and the dried onion soup mix. Brush this mixture evenly over the tops of the rolls to ensure every inch is covered.

  6. Cover the baking dish loosely with aluminum foil, making sure the foil does not touch the tops of the rolls. Bake for 25 minutes. Remove the foil and bake for an additional 5 minutes to allow the tops to become golden brown.
  7. While the sliders are in the oven, prepare the au jus gravy mix with 3 cups of water according to the package directions. Serve the warm sliders with a garnish of fresh parsley and individual bowls of au jus for dipping.

Notes

Expert Tips for the Best SlidersHerb Substitutions: If you do not have fresh thyme on hand, you can use dried herbs instead. Just remember to cut the amount in half, as dried herbs are more potent than fresh.Bread Choices: While Hawaiian sweet rolls are the favorite for this recipe because of the flavor contrast, you can use any slider buns or savory rolls you prefer.Cheese Options: Provolone and mozzarella are the best choices for a neutral, melty white cheese. If you want a bit of a kick, try swapping half the cheese for pepper jack.Make-Ahead and Storage: These sliders can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, tent them with foil in the oven until the cheese is melty again.
