Instructions

For the Horseradish Mayo:

Stir together all ingredients in a medium bowl.

For the Butter Topping:

Stir together all ingredients in a small bowl.

For the Roast Beef Sliders:

Preheat the oven to 375F. Line a small baking tray with foil and spray with avocado oil spray.
Put the entire tray of rolls onto a cutting board and horizontally slice through them. You should be able to pick up the top of the rolls as a unit.
Place the bottom half of the rolls on the prepared baking tray. Spread 1/3 of the horseradish mayo evenly across the rolls (reserving the rest for serving).
Layer on the roast beef, and then the cheese, overlapping as necessary. Place the top half of the rolls on top. Spoon on the butter sauce.
Cover the rolls with foil and bake for 25 minutes, removing the foil during the last 5 minutes.
Serve warm, along with the remaining horseradish mayo for dipping if desired.

Notes

Recipe Yield and Serving Size: This recipe makes 12 sliders; each serving is 2 sliders, for a total of 6 servings.
Make Ahead: You can assemble these sliders the day before you want to serve them, just don’t top with the butter sauce. Cover them well, and then the next day when you want to serve them, let them sit at room temperature for 20 minutes. Top with the butter sauce, cover with foil, and bake as directed.
Storage and Reheating: Store leftover sliders covered in the fridge for up to 3 days. These reheat well in the oven or air fryer at 350F. Cover them with foil to prevent over-browning. In the oven it takes about 10 to 12 minutes, and in the air fryer it takes about 5 to 6 minutes.
