Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
slider buns
deli roast beef
melted cheese (such as provolone or Swiss)
mayonnaise and/or prepared horseradish
butter
Dijon mustard
Worcestershire sauce
poppy seeds (optional)
onion powder or dried minced onion

Directions

Preheat your oven to 350°F (175°C).
Slice the slider buns in half horizontally, keeping them attached in a slab if they come connected. Place the bottom halves in a baking dish.
Spread a mixture of mayonnaise and prepared horseradish (or horsey sauce) on the buns for extra flavor.
Layer roast beef over the buns, then top with slices of cheese.
Optionally bake briefly with cheese only to melt it slightly.
In a small bowl, whisk melted butter with Dijon mustard, Worcestershire sauce, and seasonings. Pour or brush this over the tops of the rolls and sprinkle with poppy seeds.
Cover loosely with foil and bake about 15 minutes. Remove foil and bake 5–10 more minutes until buns are golden and cheese is melted.
Let cool a few minutes, then cut into individual sliders and serve.

Variations

• Swap the cheese: Swiss, Cheddar, Gouda, or Pepper Jack all work well.
• Add caramelized onions or sautéed mushrooms for more flavor.
• Use leftover roast beef or pot roast instead of deli slices.
• Brush with BBQ sauce or serve with au jus for dipping.

Storage/Reheating

Refrigerate leftover sliders in an airtight container for up to 3 days. Reheat in a 350°F oven for about 10–15 minutes covered with foil, or use an air fryer at around 320°F for a few minutes until warmed through.
