Ingredients
Scale
- 3 tablespoons unsalted butter
- 1 medium yellow onion, thinly sliced
- 2 teaspoons minced fresh thyme
- 1/4 teaspoon kosher salt
- 1/4 teaspoon black pepper
- 12 connected sweet rolls
- 10 slices provolone cheese, divided
- 14 ounces thinly 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, or the amount listed on the package
- Chopped fresh parsley for garnish, optional
Instructions
- Melt 3 tablespoons butter in a large skillet over medium heat.
- Add the sliced onion and cook for 12 to 15 minutes, stirring occasionally, until soft and golden brown.
- Stir in the thyme, kosher salt, and black pepper. Remove the skillet from the heat.
- Preheat the oven to 350°F.
- Keep the sweet rolls connected and slice the entire slab horizontally with a serrated knife.
- Place the bottom slab, cut side up, in an 11-by-7-inch or 9-by-13-inch baking dish.
- Layer half of the provolone over the rolls.
- Add the sliced roast beef in an even layer.
- Spread the caramelized onions over the beef.
- Add the remaining provolone, then replace the roll tops.
- Stir the melted butter and dried onion soup mix together in a small bowl.
- Brush the seasoned butter evenly over the tops and sides of the rolls.
- Loosely cover the baking dish with foil without letting the foil touch the rolls.
- Bake for 25 minutes.
- Remove the foil and bake for 5 additional minutes, or until the rolls turn golden and the cheese melts.
- Prepare the au jus mix with the water according to the package directions.
- Rest the sliders for 5 minutes, cut along the roll lines, garnish with parsley, and serve with warm au jus.
Notes
- Ask the deli counter to slice the roast beef very thinly for the most tender texture.
- Keep the rolls connected during assembly so the layers stay neat.
- Brush the butter mixture across the bread instead of pouring it into one spot.
- Store leftover sliders and au jus in separate airtight containers for up to three days.
- Reheat the sliders under loose foil at 325°F for 10 to 15 minutes.
