Roast beef sliders are the perfect game day food! Layers of roast beef and cheese between Hawaiian rolls are topped with the most delicious spread and cooked to perfection.
Preheat the oven to 350F and line a 9x13 baking pan or a baking sheet with aluminum foil.
Cut the sliders in half and place the bottom part in the baking pan.
In a small bowl, mix butter, whole grain mustard, Worcestershire sauce, onion and garlic powder.
Spread one tablespoon of the mixture on the sliders in the pan.
Top it with half of the roast beef.
Top the roast beef with 12 slices of cheese.
Top with the remaining roast beef and finish by placing the top part of the sliders on the roast beef.
Spread the remaining butter mixture on the sliders.
Cover with aluminum foil and bake for 12 minutes.
Uncover and bake for another 3 minutes. Serve immediately.
