1. Preheat the Oven

Preheat oven to 350°F (175°C). Grease or line a 9×13 baking dish with parchment paper.

2. Slice the Rolls

Without pulling them apart, slice the whole sheet of rolls horizontally with a serrated knife. Place the bottom half in the baking dish.

3. Layer the Fillings

Evenly layer the roast beef over the bottom half of the rolls.
Top with provolone cheese slices.
Place the top half of the rolls back on.

4. Make the Butter Glaze

In a small bowl, whisk together:

melted butter

Worcestershire sauce

garlic powder

onion powder

Brush this mixture generously over the tops of the rolls.

5. Bake

Cover tightly with foil and bake for 15 minutes.
Remove foil and bake 5–7 minutes more, until golden brown and the cheese is melted.

6. Prepare the Au Jus

While sliders bake, prepare the au jus according to package instructions. Keep warm for serving.

7. Serve

Let sliders cool 2–3 minutes, then slice along roll lines to create 12 sliders.
Garnish with chopped parsley if desired.
Serve warm with au jus for dipping.
