These copycat Arby's beef and cheddar sliders are a must-make for your next gathering. Soft Hawaiian buns topped with sliced roast beef, melty American cheese, onion flakes, and homemade Arby's sauce, brushed with a buttery glaze.
Cut the rolls in half so you have a top and bottom piece. Place the bottom half in a baking dish.
Spread the Arby's sauce on the bottom half of the slider rolls.
Add the sliced roast beef on top of the sauce in an even layer.
Add the cheese slices on top of the roast beef.
Place on the top half of the buns.
Add the butter to a small microwavable bowl. Heat until melted then mix in the onion flakes and poppyseeds. Brush the butter mixture over the buns using a basting brush.
Cover the baking dish with foil then bake for 15 minutes. Remove the foil and bake for another 5 minutes, or until the sliders are hot, the cheese is melted, and the tops of the buns are golden.
Cut into individual sliders and serve immediately.
