Feeding people shouldn’t require a culinary degree or your entire weekend. These roast beef sliders solve the eternal party problem – how to make something that looks impressive but takes almost zero skill to pull off. Seriously, it’s assembly and baking, that’s it.
The secret trick here isn’t the roast beef or even the cheese combo (though Gouda and Swiss together is genius). It’s that horseradish sauce that cuts through all the richness and makes people wonder what the heck you did differently. Hawaiian rolls bring just enough sweetness to balance the punch, while that everything bagel seasoning on top exposes your stealth Martha Stewart skills.
Bake these beauties for 15 minutes and watch twelve grown adults fight over the last slider, or people casually lurking around the kitchen, hoping you’ll make another batch. No pressure.

For the Horseradish Sauce
- Mayonnaise

Equipment
- 9×13 casserole dish
- Parchment paper or cooking spray
- Small bowls (for sauce & butter topping)

🔄 Substitutions & Variations

💡 Meat Nerd Tips
- Use a serrated knife to slice rolls cleanly without squishing.
- Check halfway through baking: If the buns brown too fast, cover with foil early.
- Pile meat per roll: Instead of spreading flat, stack slices so cutting is easier after baking.
- Sauce placement: Spread over cheese (not the bread) to avoid sogginess.
- For extra flavor: Use leftover smoked or grilled roast beef instead of deli slices. The smoky depth takes these mini roast beef sandwiches to the next level.

- Veggie platter or crudité for crunch
- French fries, chips, or onion rings for a casual dinner or game day spread
🧊 Storage and Leftovers

- Freeze: Cool completely, then freeze in a sealed bag up to 3 months. Thaw in fridge before reheating.

- Pastry brush (or spoon)
- Serrated knife
Ingredients
For the Horseradish Sauce:
- ⅓ cup mayonnaise
- 2 Tablespoons prepared horseradish
- 1 teaspoon garlic minced
For the Roast Beef Sliders:
- 1 12-pack Hawaiian rolls

- 3 slices swiss cheese
- 2 Tablespoons salted butter
- 1 teaspoon Italian seasoning
- 1 teaspoon Worcestershire sauce
- 1 Tablespoon everything bagel seasoning
Instructions
Prep the oven:
- Preheat your oven to 350°F and line a 9×13 casserole dish with parchment paper (or spray with cooking spray).
Make the horseradish sauce:
- In a small bowl, make the horseradish aioli by stirring together the mayonnaise, horseradish, and garlic until well combined.
Make the Roast Beef Sliders:
- Slice the Hawaiian rolls in half lengthwise and place the bottom half in the casserole dish.
- Place an even layer of the roast beef, top with cheese (alternating each flavor), and set aside.
- Spread the aioli on top of the cheese and place the top bun over the meat and cheese to create a sandwich.
- Melt the butter in the microwave and stir in the Italian seasoning and Worcestershire sauce.
- Brush the melted butter onto the buns and sprinkle with everything bagel seasoning.
Bake and Serve:
- Bake uncovered for 10-12 minutes. Then carefully cover with foil to prevent too much browning, and bake for another 5 minutes until golden brown, the cheese is melted, and the buns are a deep golden brown.
- Carefully remove from the oven and let rest for 5 minutes to cool. Enjoy warm.
Notes
- Fold the roast beef instead of laying it flat. Thin layers will pull out when you bite, but folding keeps the meat stacked so every bite is meaty and satisfying.
- Add caramelized onions for a serious flavor upgrade. Sweet, jammy onions pair perfectly with the roast beef and melty cheese.
- Keep an eye on the buns. If they brown too quickly, cover with foil for the last few minutes.
- Slice with a serrated knife for clean cuts without squishing the rolls.
- Sauce on the cheese, not the bread. This keeps the sauce creamy and stops the bread from going soggy.
