Ingredients (serves 6–8)

• 12 slider rolls (Hawaiian or dinner rolls)

• 8 slices provolone or Swiss cheese

• ¼ cup mayonnaise (optional)

• 2 tbsp Dijon mustard (optional)

Butter Topping

• ½ cup unsalted butter, melted

• 1 tbsp Worcestershire sauce

• 1 tsp garlic powder

• 1 tsp onion powder

• 1 tsp poppy seeds (optional)

Essential Tools and Equipment

• 9×13-inch baking dish

• Serrated knife

• Small saucepan or bowl

• Pastry brush

• Aluminum foil

Step-by-step process (detailed)

1. Preheat and prep

Preheat oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.

2. Slice the rolls

Using a serrated knife, slice the entire slab of rolls horizontally without separating them. Place the bottom half into the baking dish.

3. Spread sauce

If using, spread mayonnaise evenly over the bottom rolls, followed by Dijon mustard. This adds moisture and tang.

4. Layer the fillings

Add half of the cheese slices, then layer the roast beef evenly. Top with the remaining cheese for maximum melt.

5. Add the tops

Place the top half of the rolls over the layered filling, pressing gently.

6. Make the butter glaze

In a small bowl, whisk melted butter, Worcestershire sauce, garlic powder, onion powder, and poppy seeds until combined.

7. Brush generously

Brush the butter mixture evenly over the tops and sides of the rolls, letting it soak into the bread.

8. Bake covered

Cover loosely with foil and bake 15 minutes, allowing the sliders to heat through and the cheese to melt.

9. Uncover and brown

Remove foil and bake an additional 8–10 minutes until the tops are golden brown and slightly crisp.

10. Rest and slice

Let sliders rest 5 minutes, then slice along the roll seams and serve warm.

Mistakes to avoid

• Skipping foil at first — burned tops, cold centers

• Too little butter — dry rolls

• Overloading the beef — sliders won’t heat evenly

• Cutting too early — fillings slide out

• Low oven temp — pale tops
