Instructions

Preheat Oven: Preheat your oven to 350°F to ensure it’s ready for baking the sliders.
Prepare Rolls: Slice all the rolls in half horizontally, separating the tops from the bottoms. Arrange all the bottom halves closely together in a 9×13-inch baking pan so they touch each other, then set the tops aside for later.
Apply Mayonnaise: Spread a thin layer of mayonnaise evenly over the bottom halves of the rolls in the pan.
Add Roast Beef: Layer 1 to 2 slices of deli-sliced roast beef on each bottom roll, folding the slices as needed to fit. This folding helps keep the sliders easy to pull apart once baked.
Add Cheese and Toppings: Evenly place the provolone cheese slices over the roast beef, then put the tops of the rolls back on, gently pressing down to keep everything together and ensure even heating.
Make the Sauce: Melt the butter in a small saucepan over medium heat. Stir in the Dijon mustard, barbecue sauce, poppy seeds, and Worcestershire sauce. Let the mixture cook for 2 to 3 minutes until it just reaches a boil, then remove from heat.
Top Sliders with Sauce: Pour the warm sauce evenly over the arranged sliders in the pan. Optionally, use a pastry brush to spread the poppy seeds uniformly on top of the rolls.
Bake Covered: Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 20 minutes to heat through and begin melting the cheese.
Finish Baking: Remove the foil and bake for an additional 5 to 10 minutes until the tops are lightly browned and the cheese is fully melted and bubbly.

Notes

For best results, use thinly sliced deli roast beef no thicker than 1/8 inch to ensure tender sliders.
Folding the roast beef slices helps keep the layers neatly inside the slider and makes them easier to separate after baking.
You can customize the sauce by adjusting the barbecue sauce amount or swapping it with your preferred brand or variety.
Serving these sliders warm is best, as the cheese will be melty and the rolls soft and buttery.
This recipe yields 18 sliders, perfect for parties or larger gatherings.
