These French Dip Sliders make a fun family meal or an awesome appetizer for your next party. Hawaiian Rolls, hearty roast beef, cheese and caramelized onions. Oh my... what else can I say? You NEED to try these immediately.
Preheat oven to 350 and pull hawaiian rolls apart and cut in half. Place bottom of rolls into a baking dish. Top with cheese slices, overlapping if necessary. Set aside.
In a skillet, add 4 tbsp butter, onion and 1 tsp garlic. Cook until onions are tender, about 5 minutes. Add Worcestershire sauce, onion powder, pepper, Au Jus seasoning and roast beef.
In a small bowl, add remaining 1 tablespoon of butter and 1 tablespoon minced garlic. Melt together and stir well. Use a pastry brush to top buns with garlic butter mixture. Bake for 10 minutes or until cheese is melted.
