Ingredients
Scale
Slider Assembly
- 18 King’s Hawaiian brand sweet rolls (from two 12-count packages)
- 2 tablespoons mayonnaise
- 1-1¼ pounds deli sliced roast beef (no more than ⅛ inch thick or sandwich sliced)
- 10 slices non-smoked provolone cheese (approximately ⅛ inch thick, from an 8-ounce package)
Butter Sauce
- ½ cup salted butter
- 1 tablespoon Dijon mustard
- 1½ tablespoons bottled barbecue sauce (Sweet Baby Ray’s Original used)
- 1 tablespoon poppy seed
- 1 teaspoon Worcestershire sauce
Instructions
- Preheat Oven: Preheat your oven to 350°F to ensure it’s ready for baking the sliders.
- Prepare Rolls: Slice the King’s Hawaiian rolls in half horizontally, separating the tops from the bottoms. Arrange all the bottom halves tightly together in a 9×13 inch baking pan so they touch each other, and set the tops aside.
- Spread Mayonnaise: Evenly spread a thin layer of mayonnaise onto each of the bottom roll halves in the baking dish to add moisture and flavor.
- Add Roast Beef: Layer 1-2 slices of deli roast beef onto each bottom roll, folding the slices as needed to fit. This folding helps the sliders hold together and makes them easier to pull apart after baking.
- Layer Cheese and Tops: Place the provolone cheese slices evenly over the roast beef. Then cover with the tops of the rolls and gently press down to keep the sliders snug and ensure even heating.
- Make Butter Sauce: Melt the butter in a small saucepan over medium heat. Stir in Dijon mustard, barbecue sauce, poppy seeds, and Worcestershire sauce. Cook the mixture for 2-3 minutes until it just reaches a boil, then remove from heat.
- Apply Sauce: Pour the warm butter sauce evenly over the entire sandwich assembly. Optionally, use a pastry brush to spread poppy seeds over the roll tops for uniform distribution.
- Bake Covered: Tightly cover the baking dish with aluminum foil and bake for 20 minutes to warm through and melt the cheese.
- Finish Baking Uncovered: Remove the foil and bake an additional 5-10 minutes until the tops are lightly browned and the cheese is melted and bubbly.
Notes
- Using King’s Hawaiian sweet rolls adds a subtle sweetness that complements the savory beef and cheese.
- Folding the roast beef slices helps keep the sandwiches compact and easier to serve.
- Watching the sliders in the final bake stage prevents over-browning.
- These sliders are great for parties, game days, or casual family meals and can be easily doubled or halved.
