French Dip Hawaiian Sliders (Printable Version)

Tender roast beef, melty provolone, and sweet onions layered in Hawaiian rolls with savory dipping sauce.

# What You'll Need:

→ Filling

01 - 3 tablespoons unsalted butter
02 - 1 medium onion, thinly sliced
03 - 2 teaspoons minced fresh thyme
04 - 1/4 teaspoon kosher salt
05 - 1/4 teaspoon ground black pepper
06 - 14 ounces sliced deli roast beef

→ Slider Assembly

07 - 1 package (12 count) Hawaiian rolls
08 - 10 slices provolone cheese

→ Topping

09 - 1/2 cup unsalted butter, melted
10 - 1 1/2 tablespoons dried onion soup mix

→ Au Jus

11 - 1 packet au jus gravy mix
12 - 3 cups water

→ Garnish

13 - Fresh chopped parsley (optional)

# Steps to Follow:

01 - In a large nonstick skillet over medium heat, melt 3 tablespoons butter. Add sliced onion and sauté, stirring occasionally, for 12–15 minutes until soft and golden brown. Stir in thyme, salt, and pepper. Remove from heat and set aside.
02 - Preheat oven to 175°C. Lightly grease a 28×18 cm baking dish with nonstick spray. Without separating, slice the Hawaiian rolls horizontally to create a top and bottom slab.
03 - Place the bottom half of the rolls, cut side up, in the prepared baking dish. Layer half the provolone cheese over the rolls. Add sliced roast beef evenly on top, followed by the caramelized onions. Top with remaining cheese, then place the top half of the rolls.
04 - In a small bowl, combine melted butter with onion soup mix. Using a brush or spoon, distribute the mixture evenly over the top of the rolls.
05 - Cover loosely with foil, ensuring foil does not contact the rolls. Bake in the preheated oven for 25 minutes. Remove foil and bake an additional 5 minutes until golden brown.
06 - While sliders bake, prepare the au jus according to package instructions using 3 cups water. Heat until hot and set aside for serving.
07 - Transfer baked sliders to a serving platter. Garnish with chopped parsley if desired. Serve warm with au jus on the side for dipping.

# Additional Notes:

01 - For best flavor, allow the onions to fully caramelize without rushing; low heat and patience yield the sweetest result.
02 - Keep the rolls intact when slicing for easy assembly and clean layers.
