Roast Beef Sliders
Easy roast beef sliders with melty cheese, tangy horseradish sauce, and butter toasted buns—perfect for parties, game days, or quick dinners!
Ingredients
- 1 lb Roast Beef
- 1 tbsp Worcestershire Sauce
- 1 Yellow Onion, (diced)
- 1 tsp Onion Powder
- 1/2 tsp Garlic Powder
- 3 tbsp Mayonnaise
- 1 tbsp Dijon Mustard
- 3 tbsp Creamy Horseradish Sauce
- 6 slices Mozzarella Slices
- 6 Smoked Gouda Slices
- Crispy French Onions, (optional, for garnish)
Garlic Butter Topping
- 8 tbsp Salted Butter
- 3 cloves Garlic, (diced)
- 3 tbsp Fresh Parsley, (diced)
Instructions
- Preheat the oven to 350 degrees F. Cut the hawaiian rolls in half and place onto a parchment lined baking sheet. Bake for 5-8 minutes, until golden brown.
- Remove from the oven and increase the oven temperature to 425 degrees F.
- In a large skillet, add a drizzle of olive oil over medium heat. Add sliced roast beef and worcestershire sauce. Season with onion powder and garlic powder and cook for 2-3 minutes. Remove from the pan, leaving the juices behind. Set aside.
- Drizzle additional oil if needed, then add onions and cook for 5 minutes, until softened. Add butter and garlic and continue to cook for 3-4 minutes, until the onions and garlic have softened and caramelized slightly. Remove from heat and add parsley.
- Combine mayo, dijon mustard, and horseradish sauce in a bowl. Slather on top of the hawaiian rolls, then place mozzarella and smoked gouda cheese slices on top of the bread. (I like to alternate the slices (see the photos).
- Place the roast beef on top of the cheese, then spoon out the onions from the garlic butter sauce. Place the onions on top of the roast beef and place the other half of the bread on top.
- Pour the remaining garlic butter sauce on top of the rolls. Bake for 10-15 minutes, until the rolls are golden brown and the cheese is fully melted.
- Top with crispy french onions.
Notes
- Toast the rolls: Don’t skip the pre-bake step—it ensures the rolls hold their shape and don’t get soggy.
- Layer strategically: Start with the sauce, then cheese, followed by the beef and onions. This order guarantees melty cheese and evenly distributed flavors.
- Don’t rush the onions: Take your time caramelizing the onions. Their sweetness adds depth and balances the savory roast beef.
- Make ahead: Prep everything in advance and assemble right before baking for stress-free entertaining.
