Roast Beef Sliders

These rich and gooey roast beef sliders on Hawaiian rolls are piled high with meat and cheese. They’re made with sliced roast beef, cheddar, and BBQ sauce. Then, topped with butter and onion and baked until hot and melty. Serve them with creamy horseradish sauce, and watch them disappear!

I love making oven-baked sliders on sweet Hawaiian rolls. They make an easy and crowd-pleasing comfort food that can fit any occasion. Got leftover ham? Make Ham Delights. Need to use up Thanksgiving leftovers? Make Turkey and Cranberry Sliders. Want to impress everyone on game day? Make these roast beef and cheddar sliders with creamy horseradish sauce!

These mini roast beef sandwiches are a family-friendly, easy dinner. They get devoured at parties. They’re perfect appetizers for game day, Super Bowl parties, or tailgating. Oven-baked sliders also make a great take-along dish. You can bring them to potlucks or take a pan of them to a friend or family member. You might want to make a double batch. These babies will be devoured!

Pro-tip:  You can scale this recipe to create a double batch. You can arrange the rolls to fit 2 packs in a 9×13 pan. Just double the ingredients.

Next, I’ll tell you what you need to know about the ingredients. Then, I’ll show you step-by-step photos to make these roast beef sliders. Check out the recipe card for the exact quantities and instructions.  

Ingredients

A 12-pack of sweet Hawaiian dinner rolls such as Kings. Don’t pull them apart! 

A thin layer of sweet BBQ sauce complements the flavors and adds moisture. It doesn’t overpower the roast beef or make the sandwiches soggy. I like Sweet Baby Rays. 

Thin sliced roast beef is piled high. Using high-quality roast beef will result in a better final product. I love using deli-carved Boars Head roast beef for these. You can definitely use leftover homemade roast beef. Or, if you find yourself with leftover steak, brisket, or prime rib, you can slice it and use it to make these sliders.

Sliced cheddar cheese adds a gooey, creamy element to these sliders. And it makes them ultra-rich and decadent. You can swap for provolone or Swiss if you prefer.

Brush the rolls with butter and brown sugar mixture to add a rich flavor and a touch of sweetness. It also gives them something for the minced onion to stick to.

Sprinkle minced onions on top for a final touch that adds a savory onion flavor. I’m talking about the dried bottles of minced onion found in the spice aisle.

Easy creamy horseradish sauce with prepared horseradish, sour cream, lemon juice, and Dijon mustard. Use freshly squeezed lemon juice and prepared horseradish, not horseradish sauce. I like to serve it on the side for a couple of reasons. First, the sour cream-based sauce is better served cold rather than cooked. Second, serving the horseradish sauce on the side makes these better for picky eaters!

Substitutions & Variations

Use leftover meat: Use leftover sliced prime rib or leftover sliced brisket instead of the roast beef.

Switch up the cheese: Use provolone or Swiss instead of cheddar.

Add a crunchy topping: Top with everything bagel seasoning instead of minced onion.

Level up the flavor: If you’re a big fan of savory onions, try adding a layer of sweet caramelized onions. Spread them between the roast beef and cheese before baking!

How to Make Roast Beef Sliders

Preheat the oven to 350℉ and gather your ingredients.

Next, make your horseradish cream sauce. Mix the sour cream, lemon juice, horseradish, Dijon, and salt in a small bowl. Refrigerate it until ready to serve.

Prepare a 9×13 pan by spraying it with cooking spray. Then, use a serrated knife to cut the rolls in half horizontally. Don’t pull them apart! They should look like 1 giant hamburger bun.

Lay the bottom half of the rolls in the pan. Then, layer on the roast beef.

Next, add the cheese. Then, spread the BBQ sauce on the inside of the top half of the rolls and place them on top of the sliders.

Now, go ahead and make the butter topping. Mix the melted butter, brown sugar, and salt in a small bowl.

Use a knife to carefully cut the rolls into individual sliders. Push them back together if they start to spread apart while you slice them. This will make them easier to serve.

Then, brush the tops with the melted butter. Make sure to use all of it! Then, sprinkle them with the minced onion.

Cover the pan tightly with aluminum foil and bake at 350℉ until hot and melted.

Remove the sliders from the oven and allow them to rest for at least 5 minutes before serving.

Serve them warm with the horseradish cream sauce.

How to Make Ahead and Reheat the Sliders

To make ahead: They can be made up to 1 day in advance. Assemble the sliders and cover them with foil the night before. Then, bake them the next day before serving.

They’re a great option for meal trains for someone who is sick, grieving, or recently had a baby. You can make them in a disposable aluminum pan. Assemble them and cover the pan with foil, but don’t bake them. Write the cooking instructions in a permanent marker on the top of the aluminum foil.

To reheat in the microwave: Place them on a microwave-safe plate and heat in 15-second intervals until hot.

To reheat them in the oven: Wrap leftovers in foil and bake at 350 for a few minutes, until hot.

How to Serve Roast Beef Sliders

• Serve these sliders with the creamy horseradish sauce. Consider serving them with extra barbeque sauce for dipping. I also like to include quick pickled onions as an accompaniment.
• If you want to channel Arby’s vibes, try serving them with Catalina dressing. It’s like the red ranch sauce on their classic roast beef and cheddar sandwiches. And, FYI, they sell bags of Arby’s Curly Fries in the freezer aisle. Just sayin’. 🙂 
• I love making these as an easy, comforting family dinner. Try serving them with coleslaw, fries, pasta salad, or a simple arugula salad. 
• Make them as an appetizer or part of a party spread. They’re especially perfect for game day or for tailgating (hello Super Bowl)!
• Take them to a potluck or bring a pan of them to a family or friend who needs a comforting meal.
