Ingredients You’ll Need
This recipe calls for simple yet essential ingredients that work together beautifully to create the perfect balance of tastes and textures. Each ingredient plays its part, from the soft sweetness of Hawaiian rolls to the tangy kick of Dijon mustard and the subtle crunch of poppy seeds.
- King’s Hawaiian sweet rolls (18): These soft, sweet rolls add a pillowy texture and a subtle sweetness that complements the savory beef perfectly.
- Mayonnaise (2 tablespoons): Adds a creamy moisture layer to the rolls that keeps the sliders from feeling dry.
- Deli sliced roast beef (1-1¼ pounds): Thinly sliced for tenderness and easy folding onto each slider without bulk.
- Provolone cheese (10 slices): Melts beautifully with a mild, slightly smoky flavor that pairs perfectly with roast beef.
- Salted butter (½ cup): The base for the savory poppy seed and Dijon sauce that soaks into the tops of the rolls.
- Dijon mustard (1 tablespoon): Provides a bright, tangy depth that contrasts wonderfully with the butter and beef.
- Bottled barbecue sauce (1½ tablespoons): Adds a hint of sweetness and smokiness to enrich the buttery topping.
- Poppy seeds (1 tablespoon): Give a delightful crunch and visual appeal to the finished sliders.
- Worcestershire sauce (1 teaspoon): Adds umami depth that rounds out the beefy flavors.
How to Make Roast Beef Sliders with Poppy Seed and Dijon Butter Recipe
Step 1: Prepare the Rolls
Start by preheating your oven to 350°F. Carefully slice the King’s Hawaiian rolls in half, separating the tops from the bottoms. Arrange all the bottoms tightly in a 9×13-inch baking dish so they’re just touching — this helps the sliders stay together as they bake. Set the tops aside for later.
Step 2: Layer the Sliders
Spread a thin layer of mayonnaise over each bottom roll to add moisture and richness. Next, fold and layer 1-2 slices of roast beef onto each roll bottom, making sure to cover the surface evenly but not overstuff. This folding trick prevents sliding apart and allows easy separation after baking. Finally, evenly place provolone slices on top of the beef for that luscious melty cheese layer.
Step 3: Add the Top Rolls and Prepare the Butter Sauce
Place the top halves of the rolls on the cheese, gently pressing down to compact the sliders just enough so they bake evenly. In a small saucepan over medium heat, melt the butter. Stir in the Dijon mustard, barbecue sauce, poppy seeds, and Worcestershire sauce. Let the sauce come to a gentle boil for 2-3 minutes to marry the flavors, then remove it from the heat.
Step 4: Bake the Sliders
Pour the warm, flavorful butter sauce evenly over the assembled sliders, making sure the poppy seeds distribute nicely on top—use a pastry brush if you want to get really precise. Cover the baking dish tightly with aluminum foil. Bake for 20 minutes, then remove the foil and bake for another 5-10 minutes until the tops are golden brown and the cheese is perfectly melted and gooey.
How to Serve Roast Beef Sliders with Poppy Seed and Dijon Butter Recipe
Garnishes
For the finishing touch, consider adding some fresh arugula or baby spinach leaves for a peppery contrast and a pop of green. Thinly sliced red onions or pickles can also add brightness and crunch that complements the buttery richness of these sliders wonderfully.
Side Dishes
These sliders are perfect alongside crisp, refreshing sides like a simple coleslaw or a cucumber salad. For warm sides, crispy seasoned fries or baked potato wedges are classic companions that soak up all the extra buttery goodness.
Creative Ways to Present
Want to impress your guests? Present these sliders on a rustic wooden board or tray, with little bowls of extra Dijon mustard or barbecue sauce for dipping. You might even serve them at a party buffet with small decorative picks for easy handling and added charm.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover the sliders tightly in the baking dish or transfer them to an airtight container and refrigerate. They’ll keep well for up to 3 days while maintaining most of their fresh-baked flavor and texture.
Freezing
You can freeze these sliders assembled but unbaked. Wrap the entire baking dish tightly in foil and place it in the freezer for up to a month. To bake from frozen, keep the foil on and add extra baking time until thoroughly heated.
Reheating
Reheat refrigerated sliders in the oven at 350°F, covered with foil, until warm and the cheese is melty again—about 10-15 minutes. Avoid microwaving if possible to keep the bread from becoming soggy.
FAQs
Can I use a different type of roll?
Absolutely! While King’s Hawaiian sweet rolls are classic for this recipe, you can use any soft, slightly sweet rolls or mini sandwich buns. Just make sure they’re large enough to hold the layers comfortably.
Is it possible to make this recipe vegetarian?
To keep that buttery, tangy poppy seed flavor but without roast beef, you could substitute with grilled portobello mushrooms, roasted vegetables, or even plant-based deli slices for a vegetarian twist.
Can I prepare the sliders ahead of time without baking?
Yes, assembling the sliders and leaving them covered in the refrigerator is fine for a few hours. Just add the butter sauce and bake right before serving to ensure they stay fresh and warm.
What kind of barbecue sauce works best?
A sweeter, milder barbecue sauce like Sweet Baby Ray’s Original used in this recipe balances nicely with the Dijon and buttery mixture. Feel free to experiment with your favorite brand or flavor.
How do I make sure the sliders don’t get soggy?
Spreading mayonnaise on the bottom rolls helps create a moisture barrier. Also, avoid over-soaking with the butter sauce—pour just enough to coat the tops evenly so the bread doesn’t become too wet.

Ingredients
Slider Assembly
- 18 King’s Hawaiian brand sweet rolls (from two 12-count packages)
- 2 tablespoons mayonnaise
- 1–1¼ pounds deli sliced roast beef (no more than ⅛ inch thick or sandwich sliced)
- 10 slices non-smoked provolone cheese (approximately ⅛ inch thick, from an 8-ounce package)
Butter Sauce
- ½ cup salted butter
- 1 tablespoon Dijon mustard
- 1½ tablespoons bottled barbecue sauce (Sweet Baby Ray’s Original used)
- 1 tablespoon poppy seed
- 1 teaspoon Worcestershire sauce
Instructions
- Preheat Oven: Preheat your oven to 350°F to ensure it’s ready for baking the sliders.
- Prepare Rolls: Slice the King’s Hawaiian rolls in half horizontally, separating the tops from the bottoms. Arrange all the bottom halves tightly together in a 9×13 inch baking pan so they touch each other, and set the tops aside.
- Spread Mayonnaise: Evenly spread a thin layer of mayonnaise onto each of the bottom roll halves in the baking dish to add moisture and flavor.
- Add Roast Beef: Layer 1-2 slices of deli roast beef onto each bottom roll, folding the slices as needed to fit. This folding helps the sliders hold together and makes them easier to pull apart after baking.
- Layer Cheese and Tops: Place the provolone cheese slices evenly over the roast beef. Then cover with the tops of the rolls and gently press down to keep the sliders snug and ensure even heating.
- Make Butter Sauce: Melt the butter in a small saucepan over medium heat. Stir in Dijon mustard, barbecue sauce, poppy seeds, and Worcestershire sauce. Cook the mixture for 2-3 minutes until it just reaches a boil, then remove from heat.
- Apply Sauce: Pour the warm butter sauce evenly over the entire sandwich assembly. Optionally, use a pastry brush to spread poppy seeds over the roll tops for uniform distribution.
- Bake Covered: Tightly cover the baking dish with aluminum foil and bake for 20 minutes to warm through and melt the cheese.
- Finish Baking Uncovered: Remove the foil and bake an additional 5-10 minutes until the tops are lightly browned and the cheese is melted and bubbly.
Notes
- Using King’s Hawaiian sweet rolls adds a subtle sweetness that complements the savory beef and cheese.
- Folding the roast beef slices helps keep the sandwiches compact and easier to serve.
- Watching the sliders in the final bake stage prevents over-browning.
- These sliders are great for parties, game days, or casual family meals and can be easily doubled or halved.
