Ingredients You’ll Need
Getting ready to make these sliders is a breeze because each ingredient plays a vital role in balancing taste, texture, and color. From the sweet Hawaiian rolls to the bold horseradish cheddar, every item transforms this dish into a memorable meal.
- 2 large yellow onions peeled and thinly sliced: These slow-cooked onions add a sweet, jammy depth that’s essential for the flavor base.
- 2 tablespoons extra virgin olive oil: Used to gently caramelize the onions without burning.
- ¼ cup mayonnaise: Creates a creamy base for the tangy horseradish sauce.
- ¼ cup sour cream: Adds richness and smoothness to the sauce.
- 2-4 tablespoons prepared horseradish: Packs a sharp, zesty punch that lifts the sandwich.
- Salt and pepper to taste: Key for seasoning every element perfectly.
- 12 Kings Hawaiian rolls: The soft, slightly sweet rolls provide the perfect vessel for all the layers.
- 1 lb sliced deli roast beef shaved or chipped: Tender and juicy, this is the hearty star protein of the sliders.
- ½ lb sliced horseradish cheddar cheese: Cheddar or swiss, provolone works too, for melty, gooey goodness.
- ½ cup crispy fried onions (optional): Adds delightful crunch and extra flavor contrast.
- ¼ cup salted butter melted: Brushed on top to create a golden, flaky crust when baked.
- ½ teaspoon ground mustard (or spicy brown, dijon): Invigorates the butter topping with a subtle tang.
- ¼ teaspoon onion powder: Enhances the savory notes of the sliders.
- ¼ teaspoon garlic powder: Adds a mild, aromatic touch to the buttery crust.
- 1 tablespoon sesame seeds: For a nutty, crunchy garnish on top of the rolls.
- 1 cup beef bone broth (optional for au jus dipping): Perfect for dipping, adding moisture and that extra beefy richness.
- 1 teaspoon Worcestershire sauce: Boosts the au jus with complex umami flavors.
- Kosher salt to taste: Ensures your broth and components are perfectly seasoned.
How to Make Hawaiian Roll Roast Beef Sliders Recipe
Step 1: Caramelize the Onions
Start by peeling and slicing your onions very thinly. Cooking them slowly over low heat with olive oil will transform them into sweet, golden brown ribbons that almost resemble a jam. This process takes around 30 to 40 minutes, so patience here really pays off. Stir occasionally to prevent burning, adding water if needed to loosen browned bits. These caramelized onions infuse the entire slider with layers of sweetness and depth.
Step 2: Whisk the Horseradish Sauce
While the onions are caramelizing, combine mayonnaise, sour cream, prepared horseradish, salt, and pepper. This cool, creamy sauce is essential for cutting through the richness of the beef and cheese, and it adds just the right amount of tang to awaken your taste buds. Taste and adjust seasoning here because this sauce will flavor both the top and bottom layers of the sliders.
Step 3: Prepare the Rolls and Layer the Ingredients
Preheat your oven to 350 degrees Fahrenheit and line a 9×13-inch baking dish with parchment paper for easy cleanup. Using a serrated knife, carefully slice your Hawaiian rolls horizontally, keeping the whole loaf intact. Place the bottom half in the pan and spread a generous layer of your horseradish sauce. Pile on the roast beef, then scatter those luscious caramelized onions over it. Cover everything with cheese slices, letting them overlap the edges slightly for maximum gooeyness.
Step 4: Add Toppings and Bake
Spread more horseradish sauce on top of the cheese, then sprinkle with optional crispy fried onions for texture and extra flavor. Set the roll tops on and gently press down. Use your hands to crack open the tops slightly without detaching them, to allow the buttery sauce to seep in. Melt the butter and stir in ground mustard, onion powder, and garlic powder. Brush this mixture over the tops and sprinkle sesame seeds for that lovely finishing touch. Cover loosely with foil, bake for 10 minutes, uncover, then bake another 10 minutes until golden and bubbly.
Step 5: Prepare the Au Jus (Optional)
While the sliders bake, warm the beef bone broth with Worcestershire sauce and salt to taste. This savory dipping sauce enhances every bite by adding moistness and a punch of beefy umami.
Step 6: Slice and Serve
Once out of the oven, use a serrated knife to slice through the sliders carefully, and a spatula to serve them without losing any of their delicious layers. Serve immediately with au jus cups for dipping while piping hot.
How to Serve Hawaiian Roll Roast Beef Sliders Recipe
Garnishes
Top these sliders with extra crispy fried onions, fresh chives, or a sprinkle of cracked black pepper to add an eye-catching finish and a little extra burst of flavor. A handful of fresh arugula can also add a peppery crunch that contrasts nicely with the richness.
Side Dishes
Pair your sliders with classic sides like French fries, kettle-cooked potato chips, or a fresh coleslaw for a cool, crisp bite. If you want to keep the meal light, a simple mixed green salad with a citrus vinaigrette will balance the richness beautifully.
Creative Ways to Present
Arrange sliders on a wooden board with small bowls of au jus and horseradish sauce for dipping. Add colorful toothpicks for easy grabbing. For a fun twist, you can serve them as mini slider bar stations letting guests customize toppings like sliced pickles, jalapeños, or different cheeses.
Make Ahead and Storage
Storing Leftovers
Although these sliders are best enjoyed fresh and warm, you can assemble them in the pan up to 8 hours prior to baking and keep them covered in the fridge. Once baked, any leftovers should be refrigerated promptly, but note the rolls may get soggy over time.
Freezing
Freezing is not recommended for this recipe due to the delicate texture of the rolls and caramelized onions, which lose quality when frozen and reheated. For best results, enjoy fresh or store baked leftovers for only a day or two.
Reheating
To reheat, place the sliders in a 350-degree oven covered with foil to maintain moisture and bake until warmed through, about 10-15 minutes. Avoid microwaving as it can make the rolls chewy and the cheese separate.
FAQs
Can I use other types of rolls for this recipe?
Absolutely! While Hawaiian rolls give a sweet, soft contrast to the savory filling, you can use any slider rolls or soft sandwich buns you prefer. Just keep in mind that the texture and flavor will vary slightly.
Is the au jus necessary?
The au jus is optional but highly recommended if you love dipping. It intensifies the beef flavor and adds moisture, elevating the sliders to a restaurant-quality experience.
Can I make this recipe vegetarian?
You could substitute the roast beef with grilled portobello mushrooms or a hearty veggie patty. Keep the horseradish sauce and caramelized onions for their bold flavors.
How spicy is the horseradish sauce?
The heat level depends on how much horseradish you add. Start with 2 tablespoons and increase if you like a stronger kick, but remember it should complement, not overpower, the other flavors.
Can I prepare the sliders in advance?
Yes! Assemble everything except for baking, then cover and refrigerate for up to 8 hours before baking fresh when you are ready to serve. Just add a few extra minutes if baking cold from the fridge.

- Prepare the onions: Peel, halve, and thinly slice the onions. Heat a large skillet over medium-low heat, add olive oil and onions, tossing to coat. Cook for 5 minutes, then reduce heat to lowest setting and cook 30-40 minutes, stirring every 5 minutes until onions are golden brown and jammy. If onions start burning, add ¼ cup water to loosen browned bits. Remove from heat and let cool.
- Make the horseradish sauce: While onions cook, whisk together mayonnaise, sour cream, prepared horseradish, salt, and pepper. Adjust seasoning to taste.
- Preheat and prepare pan: Preheat oven to 350°F (175°C). Line a 9×13” pan or small sheet pan with parchment paper.
- Slice rolls: Carefully slice Hawaiian rolls in half lengthwise through the soft centers, keeping the loaf intact.
- Assemble slider bases: Place bottom halves of rolls in the pan. Spread horseradish sauce generously over the bottoms.
- Add fillings: Layer the sliced roast beef evenly over the horseradish sauce, then top with the caramelized onions. Cover completely with slices of horseradish cheddar cheese, letting some cheese hang over the edges.
