These Roast Beef & Swiss Party Sandwiches are perfect for gatherings and game days, featuring tender roast beef layered with melty Swiss cheese, all nestled inside buttery slider buns and baked to golden perfection for a warm, savory treat.

Ingredients

Scale

Buns and Meat

  • 12 slider buns
  • 1 lb thin-sliced roast beef

Cheese

  • 8 slices Swiss cheese, halved

Spread

  • ¼ cup mayo
  • 1 tbsp Dijon mustard

Topping

  • 2 tbsp melted butter
  • ½ tsp garlic powder
  • ½ tsp onion powder

Instructions

  1. Prepare the spread: In a small bowl, mix together the mayonnaise and Dijon mustard until smooth. This mixture will add a creamy, tangy flavor inside the buns.
  2. Assemble the sandwiches: Slice the slider buns horizontally. Spread the mayo-Dijon mixture evenly on the inside of each bun. Layer the bottom halves of the buns with thinly sliced roast beef, then top with halved Swiss cheese slices.
  3. Close and season: Place the top halves of the buns onto the layered bottoms. In a separate small bowl, combine melted butter with garlic powder and onion powder, then brush the mixture generously over the tops of the sandwich buns to add flavor and help with browning.
  4. Bake the sandwiches: Preheat the oven to 350°F (175°C). Place the assembled sandwiches on a baking sheet, cover them with foil, and bake for 12 minutes to warm and melt the cheese thoroughly.
  5. Brown the tops: Remove the foil and bake uncovered for an additional 5 minutes. This step crisps the tops of the buns to a golden brown, adding a delicious texture contrast.
  6. Serve warm: Remove from the oven and serve immediately to enjoy the warm melt of the Swiss cheese and savory roast beef.

Notes

  • You can substitute cheddar or provolone cheese for a different flavor.
  • For an extra kick, add a few slices of pickles or a dash of horseradish sauce inside the buns.
  • These sandwiches can be assembled ahead and refrigerated; bake just before serving.
  • Use fresh slider buns for best texture; stale buns won’t crisp up as nicely when baked.
