Description
These roast beef sliders are warm, cheesy, tender, and irresistibly buttery—perfect for parties, game days, or a simple weeknight dinner.
Ingredients
- 1 package (12-count) Hawaiian sweet rolls
- 12–18 slices thinly sliced deli roast beef
- 10–12 slices provolone cheese (or sharp white cheddar, Havarti, or Swiss)
- 1–2 large sweet onions, thinly sliced
- 1 tablespoon olive oil
- 2 tablespoons salted butter
- Prepared horseradish (optional)
- ½ cup melted butter
- 2 tablespoons brown sugar
- 1 tablespoon spicy brown mustard (or Dijon or yellow mustard)
- 1 tablespoon Worcestershire sauce
- ¼ teaspoon garlic powder
- ¼ teaspoon onion powder
- ½ teaspoon dried thyme
Instructions
- Preheat the oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
- In a skillet over medium heat, add the olive oil and 2 tablespoons butter. Sauté the sliced onions, stirring occasionally, until soft, browned, and caramelized—about 15–30 minutes. Reduce heat as needed.
- Without separating the rolls, slice the entire slab horizontally, keeping the bottom thicker than the top. Place the bottom half into the baking dish.
- Spread a thin layer of horseradish on the bottom rolls if desired.
- Layer the roast beef evenly over the rolls, followed by the cheese slices. Spoon the caramelized onions over the cheese. Place the top half of the rolls back on.
- In a small saucepan, combine the melted butter, brown sugar, mustard, Worcestershire sauce, garlic powder, onion powder, and dried thyme. Warm until the sugar dissolves.
- Pour the sauce evenly over the sliders, brushing to ensure full coverage. Cover with lightly greased foil.
- Bake for 20 minutes. Remove the foil and bake an additional 7–10 minutes until the tops are lightly browned.
- Serve warm.
Notes
- Caramelized onions add rich flavor, but you can use lightly sautéed onions if short on time.
- Make ahead: assemble up to 12 hours in advance and refrigerate before baking.
- Use gluten-free rolls for a gluten-free version.
- To reheat, bake at 325°F (165°C) for 15–20 minutes.
- Freezes well before or after baking.
