Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• 12 slider buns (like dinner rolls or Hawaiian sweet rolls)
• 1/2 cup mayonnaise
• 2 tablespoons prepared horseradish
• 1 pound thinly sliced deli-style roast beef
• 6 slices sharp provolone cheese
• 4 tablespoons unsalted butter, melted
• 1/2 tablespoon packed light brown sugar
• 1 tablespoon Dijon mustard
• 2 teaspoons finely minced sweet onion
• 1 tablespoon Worcestershire sauce
• 1/2 teaspoon coarse salt
• 1 tablespoon poppy seeds

Directions

1. Preheat the oven to 350°F and grease a 9-by-13-inch baking dish.
2. Slice the buns horizontally (keeping the set intact if possible) and place the bottom halves into the prepared dish.
3. Mix the mayonnaise and horseradish in a small bowl. Spread on the bottom halves of the buns.
4. Layer the roast beef and provolone cheese over the spread. Place the top halves of the buns over the filling.
5. In a small saucepan, melt the butter with the brown sugar over low heat. Once dissolved, remove from heat and whisk in the mustard, onion, Worcestershire, and salt.
6. Spoon the butter mixture evenly over the sliders. Sprinkle with poppy seeds.
7. Cover with foil and bake for 10 minutes. Uncover and bake an additional 8-10 minutes, until golden and the cheese is melted.

How do I serve these at a party?
