Step 1: Preheat your oven to 375°F (190°C). Line a 9×13 inch baking dish with parchment paper. Carefully slice the entire slab of Hawaiian rolls horizontally using a large serrated knife, keeping the top and bottom halves intact.
Step 2: Place the bottom half of the rolls into the prepared baking dish. Layer the roast beef evenly over the bottom rolls, folding if necessary. Top the roast beef with the provolone cheese slices, ensuring good coverage.
Step 3: Place the top half of the rolls over the cheese and roast beef layers. In a small bowl, combine the melted butter, Worcestershire sauce, Dijon mustard, onion powder, garlic powder, salt, and pepper. Whisk until well combined.
Step 4: Evenly pour the butter mixture over the top of the assembled sliders. Brush gently to ensure every roll is coated. Cover the baking dish tightly with aluminum foil.
Step 5: Bake for 15 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the tops are golden brown and the cheese is bubbly and melted. While baking, prepare your Rudolph decorations.
Step 6: Once baked, remove from the oven and let cool for a few minutes. Carefully separate the sliders. Garnish each slider with two pretzel antler halves, two olive slices for eyes, and one roasted red pepper circle for Rudolph’s nose. Serve warm and enjoy!
