Ingredients
Equipment
Method
- Preheat the oven to 350°F (175°C). Slice the Hawaiian rolls horizontally, keeping the tops and bottoms connected.
- Place the bottom half of the rolls into a baking dish or onto a baking sheet. Gently separate the individual rolls, then push them back together.
- In a microwave-safe bowl combine the butter, prepared horseradish sauce (or Arby’s Horsey Sauce), and minced garlic. Microwave until the butter has melted, then stir well to combine.
- Brush about half of the horseradish butter over the cut side of the bottom rolls.
- Divide half of the roast beef between the sliders, loosely folding the meat onto each roll.
- Place one quarter slice of cheddar onto each slider.
- Repeat with the remaining roast beef, then top each slider with another quarter slice of cheddar.
- Place the connected tops of the rolls over the filling.
- Brush the remaining horseradish butter generously over the tops of the rolls.Then you can sprinkle over the optional dried minced onion and poppy seeds if you prefer, or leave without.
- Cover loosely with foil and bake for 20 minutes. If baking in a glass dish, begin checking a couple of minutes early as glass tends to brown the bottoms more quickly than metal or ceramic.
- Remove the foil and continue baking for 3 to 5 minutes, until the tops are lightly golden and the cheese is fully melted.
- Rest for 2 to 3 minutes before pulling the sliders apart and serving warm.
Notes
- Prepared horseradish sauce is much milder than straight horseradish and gives these sliders their classic roast beef sandwich flavor.
- Arby’s Horsey Sauce can be used instead of prepared horseradish sauce if you can find it.
- Fold the roast beef rather than laying it flat so every slider has a generous bite.
- Layering the roast beef and cheddar twice helps every slider stay evenly filled.
- Shredded cheddar can be substituted by dividing it evenly between both cheese layers.
- Sprinkle the optional dried minced onion and poppy seeds over the buttered tops before baking if you’d like an even closer nod to classic Arby’s sandwiches.
- Glass baking dishes brown the bottoms of the rolls more quickly than ceramic or metal. Begin checking a little early and shorten the uncovered baking time if needed.
Storage
- Store leftover sliders in an airtight container in the refrigerator for up to 3 days.
- Reheat in a 325°F oven for 8 to 10 minutes, or until the roast beef is warmed through and the cheese is melted and the roast beef is warmed through. Cover loosely with foil if the tops are already browned.
- These sliders are best enjoyed fresh, as freezing can affect the texture of the Hawaiian rolls and melted cheese.
