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.
Add the 12 ounces deli roast beef on top of the sauce in an even layer.
Add the 6 slices American cheese on top of the roast beef.
Place on the top half of the buns.
Add 3 tablespoons butter, to a small microwavable bowl. Heat until melted, then mix in 1 teaspoon dried onion flakes and a dash poppy seeds. Brush the butter mixture over the buns using a basting brush.
Cover the baking dish with foil, and 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.
