• Unsalted butter: 4 tbsp, melted, for brushing over the rolls.
• Worcestershire sauce: 1 tsp, for savory depth in the butter topping.
• Onion powder: 1/2 tsp, for flavor in the topping.
• Garlic powder: 1/4 tsp, for an aromatic touch in the butter topping.
• Fresh parsley: 1/2 tbsp, chopped, for garnish and butter topping.
• Beef broth: 2 cups, for the jus.
• Unsalted butter: 2 tbsp, melted for the jus.
• Garlic: 1 clove, minced, for aromatic depth in the jus.
• All-purpose flour: 1.5 tbsp (optional), for thickening the jus.
• Worcestershire sauce: 1 tbsp, for rich flavor in the jus.
• Roasted beef base: 1-2 tsp (optional), for an extra depth of flavor in the jus.

INSTRUCTIONS

Step 1:

Preheat your oven to 350°F and grease a baking dish. Slice slider rolls horizontally into tops and bottoms, then broil cut sides for 1-2 minutes until lightly toasted.

Step 2:

Spread half the mayo-horseradish mixture on the toasted roll bottoms and place them in the greased baking dish.

Step 3:

Layer half the cheese, all of the roast beef, caramelized onions, and the remaining cheese over the roll bottoms.

Step 4:

Spread the remaining mayo-horseradish mixture on the roll tops and place them over the filling.

Step 5:

In a small bowl, mix melted butter, Worcestershire sauce, onion powder, garlic powder, and parsley. Brush generously over the rolls.

Step 6:

Cover the sliders with foil and bake for 20 minutes. Remove the foil and bake for an additional 5-8 minutes until golden.

Step 7:

For the jus, sauté minced garlic in melted butter. Stir in flour if using, and cook briefly. Gradually whisk in beef broth, Worcestershire sauce, thyme, and beef base if needed. Simmer for 10 minutes, then season to taste and strain for a smooth dip.

Step 8:

Slice the sliders, garnish with fresh parsley, and serve with warm jus for dipping.

Serving and Storage Tips

• Serve hot with a side of warm jus for dipping.
• Store leftovers in the refrigerator for up to 3 days. Reheat in the oven for the best texture.

Helpful Notes

• For extra flavor, add sautéed mushrooms or peppers to the filling.
• If you prefer a spicier dip, add a pinch of red pepper flakes to the jus.

Tips from Well-Known Chefs

• Use high-quality deli roast beef for the best flavor and tenderness.
• Toast the rolls lightly to prevent sogginess from the filling.
