Roast Beef Sliders bring tender beef, creamy provolone and sweet rolls together in a warm, buttery bite. A little Dijon mayo adds tang without making the bread soggy. The tops get a savory herb-butter coating, then bake until lightly golden. Set out the pan for a party, or add a crisp salad for a simple dinner.
Why I Love This Recipe
These small sandwiches have plenty of flavor without a long ingredient list. The roast beef is already cooked, so the oven warms the filling while the cheese melts and the bread picks up a light toast.
- Easy assembly: Slice the connected rolls as a slab, then build the layers in one dish.
- Balanced flavor: Sweet bread softens the sharpness of Dijon and savory beef.
- Easy portions: Cut between the rolls for tidy sandwiches that are simple to share.
- Flexible timing: Assemble the filling ahead and add the butter topping just before baking.
What You’ll Need
- Servings: 12 sliders; 6 meal servings of 2 sliders
- Prep Time: 15 minutes
- Cook Time: 25 minutes
- Rest Time: 5 minutes
- Total Time: 45 minutes
- Oven Temperature: 350°F (175°C)
- Pan Size: 9×13 inches
- 1 package (12 count, about 12 ounces) Hawaiian sweet rolls
- 1 pound thinly sliced, fully cooked deli roast beef

How to Make Roast Beef Sliders
Keep the rolls connected while you build the layers so the filling stays evenly spread.
Step 1: Prepare the Rolls
Preheat the oven to 350°F (175°C).
Line a white 9×13-inch rectangular ceramic baking dish with parchment across the base and up the long sides. Keep paper below the top of the dish.
Slice 1 package of 12 Hawaiian rolls horizontally through the middle without separating the individual rolls.
Place the bottom slab cut-side up in the dish and set the top slab aside.
Step 2: Mix the Dijon Spread
Stir 1/4 cup mayonnaise with 1 tablespoon Dijon mustard in a small bowl until smooth.
Keep the remaining 1 tablespoon Dijon mustard for the butter topping.
Step 3: Layer the Filling
Spread all the Dijon-mayonnaise mixture from Step 2 thinly over the cut roll bottoms.
Fold 1 pound thinly sliced deli roast beef evenly over the bread, keeping a similar amount over each roll.
Place 12 thin square provolone slices, totaling 6 ounces, above the beef. Give each roll its own square slice, with clear boundaries and no overlapping slices.
Step 4: Make the Butter Topping
Melt 4 tablespoons unsalted butter in a microwave-safe bowl in 15-second bursts until just liquid.
Stir in the remaining 1 tablespoon Dijon mustard, 2 teaspoons Worcestershire sauce, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder and 1 teaspoon dried parsley.
Mix well so the fine herb flecks are spread through the thin golden-tan topping.
Step 5: Close and Bake
Replace the reserved upper bread slab, matching each top to its bottom roll.
Brush all the seasoned butter from Step 4 evenly over the 12 roll tops, stirring the bowl as needed so each top gets some parsley.
Cover the dish loosely with foil and bake for 20 minutes.
Remove the foil and bake for 5 minutes, until the tops are lightly golden, the cheese is completely melted and the center is heated through. Check the center filling for 165°F (74°C), especially when using leftover roast beef; extend the covered baking time if needed.
The bread should settle against the filling and the cheese should feel soft throughout. If the tops brown before the center is ready, cover loosely again.
Step 6: Rest and Serve
Let the sliders rest in the dish for 5 minutes so the filling settles.
Cut between the rolls, then lift them out with a wide spatula. For a shared serving tray, arrange several whole sliders loosely around a cut half that shows the beef and melted cheese.
Serve warm. Add coleslaw or a green salad on the side if you want a fuller meal.
Why This Recipe Works (Quick Science)
Thin beef slices heat faster than thick pieces and fold neatly into small rolls. Covering the dish holds in moisture while heat reaches the center. The uncovered finish gives the buttered tops a light toast without drying the whole sandwich.
Provolone softens into the folds of beef and helps hold each sandwich together. A short rest lets the melted filling settle before cutting. The thin mayo layer adds richness, while Dijon balances the sweetness of the bread.
Common Mistakes to Avoid
- Using thick beef: Thick slices are harder to bite through and take longer to warm.
- Piling filling in the middle: Spread the beef over every roll so the outside sliders get their share.
- Adding too much spread: A thin layer gives flavor without soaking the bread.
- Baking uncovered the whole time: The tops can darken while the middle is still cool.
- Skipping the center check: Melted cheese near the edges does not prove the center is ready.
What to Serve With Roast Beef Sliders
A crisp green salad or tangy coleslaw balances the rich filling. Roasted potato wedges make a heartier dinner, while raw vegetable sticks work well for a party spread. These are optional sides; the sliders are flavorful enough to serve on their own as an appetizer.
Make-Ahead and Storage
Assemble the bread, Dijon spread, beef and cheese up to 24 hours ahead. Cover and refrigerate promptly. Store the butter topping separately and brush it on just before baking. A chilled batch may need extra covered baking time; use the center temperature rather than the clock alone.
Refrigerate leftovers in a shallow airtight container within 2 hours. Keep for up to 3 days, counting from when the beef was originally cooked or opened if it was already stored. Do not restart the storage clock by baking older leftovers.
Reheat loosely covered in a 325°F (165°C) oven until the center reaches 165°F (74°C). Uncover briefly at the end to refresh the tops. Freeze cooled sliders individually for up to 2 months for best texture, then thaw in the refrigerator before reheating.

Frequently Asked Questions (FAQ)
Q: Can I use leftover roast beef?
A: Yes. Slice fully cooked roast beef thinly across the grain and use 1 pound. Warm the center filling to 165°F (74°C) and keep the original storage date in mind.
Q: What kind of roast beef should I buy?
A: Choose thin deli slices that fold easily. Pat away excess surface moisture so it does not soak into the rolls.
Q: Can I use a different cheese?
A: Mild Swiss or white cheddar can replace the provolone by weight. Use 6 ounces total and divide it evenly among the rolls.
Q: Do I have to use Hawaiian rolls?
A: No. Similar soft slider rolls work too. Choose a connected package of 12 that fits the dish, and expect a less sweet flavor with plain rolls.
Q: How do I keep the bottoms from getting soggy?
A: Use dry-surfaced beef, spread the mayo thinly and keep the butter topping on the upper bread. Avoid adding broth to this version.
Q: Can I double the recipe?
A: Yes. Use two separate 9×13-inch dishes so the sandwiches stay in a single layer. Check each dish for a fully heated center.
Q: Why has my cheese not melted in the middle?
A: The center may need more covered baking time, especially if the sliders were chilled. Keep the tops protected with foil while the filling finishes heating.
Q: Can I leave out the mayonnaise?
A: You can, but the filling will be less creamy. Spread the 1 tablespoon Dijon intended for that layer thinly on the bread, and leave the topping amounts unchanged.
