Instructions

Preheat the oven: Set your oven to 350°F (175°C) to prepare for baking the sliders.
Prepare the rolls: Slice the King’s Hawaiian rolls in half horizontally, separating the tops from the bottoms. Arrange all the bottom halves snugly in a 9×13-inch baking pan so they touch each other. Set the tops aside for later use.
Apply mayonnaise: Spread a thin, even layer of mayonnaise onto each bottom roll in the baking dish.
Add roast beef: Place 1 to 2 slices of deli roast beef on each roll bottom, folding the slices as needed to fit the rolls. This layering helps make the sliders easy to pull apart after baking.
Add cheese and top rolls: Lay the provolone cheese slices evenly over the roast beef, then place the tops of the rolls on the cheese layer. Gently press down on the assembled sliders to ensure they hold together and heat evenly while baking.
Prepare the sauce: In a small saucepan over medium heat, melt the butter. Stir in Dijon mustard, barbecue sauce, poppy seeds, and Worcestershire sauce. Bring the mixture just to a boil, then remove from heat.
Brush the sauce: Pour the warm sauce evenly over the assembled sliders, making sure to drizzle it thoroughly. Optionally, use a pastry brush to spread poppy seeds evenly over the tops of the rolls for extra texture and flavor.
Bake the sliders: Cover the baking dish tightly with aluminum foil and bake for 20 minutes. Remove the foil and continue baking for an additional 5 to 10 minutes, until the tops are lightly browned and the cheese has melted.

Notes

You can substitute the provolone cheese with mozzarella or Swiss cheese if desired.
For a spicier version, add a little horseradish sauce to the mayonnaise spread.
These sliders are best served warm and fresh but can be reheated covered in foil at 325°F for 10-15 minutes.
To make prep easier, you can slice rolls and prepare sauce ahead of time and assemble just before baking.
Use thinly sliced roast beef for the best texture and easy layering.
