These Roast Beef Sliders are filled with layers of roast beef, provolone cheese, and plenty of horseradish mayo.
Perfect served as finger food for your next party or as a main dish for lunch or dinner.
Mini hot roast beef sandwiches
Roast beef sliders with provolone cheese are a delicious mini sandwich that combines the rich flavors of tender roast beef and creamy provolone cheese. These bite-sized sandwiches are perfect for parties, game nights, or any casual gathering.
The provolone cheese adds a creamy, melty layer that's perfect with the sliced roast beef. However, feel free to use your favorite cheese. Cheddar or pepper jack would be delicious too!

Step-by-step directions
In this section, I share step-by-step photos, cooking methods, techniques, and a general overview. For detailed instructions, temperatures, and timing, check the printable recipe card below.
- Prepare horseradish mayo by combining mayonnaise, horseradish, and mustard together in a bowl.
- Melt butter, mustard, Worcestershire sauce, and onion powder together. Turn off the heat as soon as the butter is melted. Mix to combine.
- Slice buns in half. If the buns are attached, leave them as one large slab and slice the entire slab in half.
- Place the bottom half of the buns in an ungreased baking dish.
- Spread the mayo over both sides of the buns.
- Layer roast beef and then cheese on the buns.
- Place the top half of the buns and then brush on butter over the top and side of the buns. Use all the butter mixture.
- Sprinkle with poppyseeds and cover the pan with foil
- Bake in a preheated 350°F oven for 20-25 minutes until the sliders are heated through and the cheese is soft and melty.
- Remove the sliders from the baking dish and separate each slider by slicing between each bun.
- Serve hot or warm.
Recipe tips
- The amount of horseradish is flexible. Add more for a spicier sauce or add less for a milder sauce.
- Keeping the entire slab of rolls intact makes assembly easier. If you prefer, you can detach the rolls and assemble each roll individually.
- These sliders can be made into full-sized sandwiches. Use regular-size hamburger buns and assemble each bun individually. Sandwiches can be wrapped individually or placed on a baking sheet and then covered with foil.
Frequently asked questions
Yes, you can assemble the sliders, cover and refrigerate them up to one day ahead of time. Just bake as directed, increasing the baking time by 5-10 minutes.
