Ingredients

Scale

For the Sliders

2 tablespoons unsalted butter
1 medium onion, thinly sliced
1 teaspoon garlic powder
1 teaspoon pepper
1 teaspoon salt
12 Hawaiian Sweet Rolls
12 slices deli roast beef
12 slices provolone cheese

For the Topping

3 tablespoons unsalted butter, melted
2 tablespoons onion soup mix (such as Lipton brand)

For the Au Jus Sauce

1 packet au jus mix
3 cups water

Optional Garnish

Fresh chopped parsley

Instructions

Preheat Oven: Preheat your oven to 375°F (190°C) and prepare a 9×13 inch baking dish by spraying it with cooking spray or lining it with parchment paper.
Caramelize Onions: In a medium skillet, melt 2 tablespoons of butter over medium heat. Add the thinly sliced onions, garlic powder, salt, and pepper. Sauté until the onions are tender and caramelized, stirring occasionally to avoid burning.
Prepare Rolls: Carefully slice the Hawaiian sweet rolls horizontally to create a top and bottom half. Remove and set aside the top half of the rolls.
Assemble Sliders: Place the bottom half of the rolls into the prepared baking dish. Layer evenly with the deli roast beef slices, followed by the sautéed caramelized onions, and then top with slices of provolone cheese. Replace the top half of the rolls over the cheese layer.
Apply Butter Mixture: In a small bowl, whisk together the melted butter with the onion soup mix until well combined. Brush this mixture evenly over the entire top of the rolls to add flavor and aid browning.
Bake the Sliders: Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 15 minutes. After 15 minutes, remove the foil and continue baking until the cheese has melted and the tops are golden brown, about 5 to 7 more minutes.
Prepare Au Jus: While the sliders bake, combine 3 cups of water and the packet of au jus mix in a small saucepan. Bring to a boil over medium-high heat, then reduce the heat and simmer until the sauce thickens slightly, about 5 minutes.
Serve: Slice the sliders and serve warm, accompanied by the hot au jus sauce for dipping. Garnish with fresh chopped parsley if desired for added color and freshness.

Notes

You can substitute provolone cheese with Swiss or mozzarella for a different flavor profile.
If you prefer a spicier kick, add a pinch of red pepper flakes to the caramelized onions.
Use fresh onions and cook slowly to get the best caramelization and sweetness.
The au jus mix can be found at most grocery stores near soup or gravy mixes.
These sliders can be made ahead and baked just before serving for convenience.
For a gluten-free version, substitute the Hawaiian rolls with gluten-free buns.
