Roast Beef Sliders

Whether you call these roast beef sliders, sandwiches, or mini grinders, we can all agree they are delicious! Thinly sliced roast beef layered between sweet Hawaiian rolls with cheese, and caramelized onions. A savory butter sauce over the top really makes them stand out and helps them brown in the oven too.
These roast beef sliders on Hawaiian rolls are great for holiday parties, game day, or anytime you want to make a meal in advance. I also love them for a New Year’s Eve snack — or the next day when we’re all still tired!
Truly, they’re perfect for any celebration (hello Super Bowl) and easy enough for the kids to help! They can get the rolls layered and ready while you cook the onions and whip up the sauce.
Aside from baked slider sandwiches, your guests will love my Easy Instant Pot Buffalo Chicken that explodes with just the right amount of heat! Or, make a tray of Caprese BLTs for a lighter option!
Ingredients
The full list of ingredients and measurements are in the printable recipe card at the end of this post.
- Deli Roast Beef | Ask the deli counter to slice it thin for this recipe, I used sliced prime rib for an upgraded sandwich.
- Hawaiian Bread Rolls | These are unique because they’re sweeter than other varieties, pairing perfectly with the flavorful sauce.
- Cheese | Use a good melting variety like provolone, sharp white cheddar, Havarti, or Swiss.
- Onion | Sweet varieties like Vidalia or Walla Walla are best, but you could easily get away with a red onion if needed.
- Butter | Melt this down to make the sauce for the roast beef sliders.
- Brown Sugar | I use Dixie Crystals Light Brown in this recipe, just a touch adds a hint of sweetness!
- Worcestershire Sauce | There is a trace amount of fish in this sauce, so if you have a fish allergy, substitute with dark molasses mixed with vinegar and water.
- Spicy Brown Mustard | Earthier than regular mustard, this plays off the Worcestershire and tastes incredible with the meat.
- Spices | I use a combo of garlic and onion powder with dried thyme.
- Horseradish | This is optional but really goes well with the other flavors.
Instructions
Preheat your oven to 350 degrees F and lightly spray a large baking dish (9×13 pan works great).
Over medium-low heat, slowly caramelize the onions in skillet with butter and oil, stirring often until they are softened and browned, it will take about 15-30 minutes.
TFC TIP | For thinly sliced, easy to caramelize onions, use a mandolin style slicer for evenly and easily sliced onions. This economical version is my favorite!
Slice the slab of rolls evenly in half lengthwise, leaving them all connected to each other. Nestle the bottom half into your baking dish (9×13), splitting it into rows as needed so it fits.
Layer on the meat, cheese, and onions before covering everything with the tops of the rolls. If you know everyone loves spicy, then spread with a thin layer of horseradish, if not, leave it off and serve on the side.
For the sauce, melt butter in a small saucepan. Add the mustard, brown sugar, Worcestershire, and spices, stirring until the sugar dissolves and the sauce thickens.
Pour the sauce over the Hawaiian rolls, brushing sauce to cover evenly. Cover with aluminum foil and bake for about 25 minutes. Then, remove the foil and bake for another few minutes until the tops are lightly browned.
You can serve these fresh from the oven or allow them to cool slightly first before slicing. Have plenty of mustard and horseradish ready!
Variations & Substitutions
- You can also use whole wheat, Brioche rolls or pretzel rolls for this roast beef sliders recipe, just make sure they are nice and soft, a hard roll won’t work well in this recipe.
- Substitute beet horseradish for regular horseradish, it adds a lovely pop of red (I leave mine on the side so everyone can make theirs as spicy as they like!)
- Add some extra tang and crunch with pickles! Include a layer of long pickle slices or bread and butter chips between the cheese and caramelized onions.
- Gluten-Free Roast Beef Sliders | Yes! Swap out the Hawaiian bread rolls for gluten-free slider buns.
- Don’t need as many? Easily cut the recipe in half or double for a crowd!
- Poppy Seeds | As you can see there is no poppy seeds for these roast beef sliders on Hawaiian rolls, that’s because I am not a fan, black specks stuck in teeth and all. But if you like, you can certainly add a ½ – 1 teaspoon to the buttery sauce or just sprinkle some on top after adding the sauce.
TFC Pro Tips
- Pro Tip 1 | Just like my Hammy Sammies or Turkey Sliders, you may prep this entire dish (sauce included) and refrigerate covered up to 12 hours before baking.
- Pro Tip 2 | A cheese slicer will save you time and effort. It’s also the perfect way to guarantee that each slice is an even thickness.
- Pro Tip 3 | Use a large bread knife to slice your rolls in half. The serrated edge cuts cleanly like a saw without compressing or tearing the rolls.
Frequently Asked Questions
Look for one that is low in sodium and not overly processed. I personally love organic brands like Boar’s Head.
Be sure to slice the rolls evenly so the bottom half isn’t too thin. You can also toast the bottom half in the oven for a few minutes before you start assembling everything. But the buttery sauce and the melting cheese caramelizes on the bottom creating a delicious, warm, slightly sweet crust.

Storage & Freezing
Store any leftovers in the fridge in an airtight container, rewarm in 300 degree oven for 15-20 minutes.
Can I freeze Roast Beef Sliders?
Hawaiian roll sliders also known as Funeral sandwiches and they are extremely freezer friendly. Make up a bunch ahead of time and pop in the freezer. If frozen, cook in a 300 degree oven for 15-20 minutes longer. I recommend thawing in the fridge before baking, bake as directed.

Ingredients
Roast Beef Sliders
- 1 package 12 count Hawaiian Bread rolls (see notes for options)
- 12-18 slices of deli roast beef sliced thin
- 10-12 slices of provolone sharp white cheddar, Havarti or Swiss cheese
- 1-2 sweet onions or red onion sliced thin
- 1 tablespoon olive oil
- 2 tablespoons salted butter or add sub with additional olive oil

Sauce
- ½ cup butter melted
- 2 tablespoons brown sugar

Instructions
- Preheat oven to 350 degrees F and lightly spray a 9×13 inch baking dish with cooking spray oil.
- Heat skillet over medium heat, adding butter and oil. Saute sliced onions in butter and oil until soft, brown and slightly caramelized, reduce heat to low if necessary. Stirring occasionally, about 15-30 minutes.
- In the meantime, prepare the sliders. Slice the “loaf” of Hawaiian rolls in half lengthwise, keeping the top intact. If desired, spread with a little prepared horseradish, I skip this step allowing my eaters to add if they choose.
- Layer roast beef to slider bottoms, then layer cheese over the top of the roast beef, finishing with caramelized/sautéed onions. Cover with tops of bread rolls.
- In a small saucepan, melt butter over medium heat, add brown mustard, brown sugar, Worcestershire sauce, garlic and onion powder and dried thyme, stirring until sauce is warmed, sugars have dissolved.
- Evenly pour over the tops of the Hawaiian rolls, if necessary brushing to cover all sides of the sandwiches. Cover with aluminum foil and bake in preheated oven about 25 minutes. Remove foil and bake for an additional 7-10 minutes until tops are lightly browned.
- Just like my Hammy Sammy’s or Turkey Sliders , you may prep this entire dish, sauce included and refrigerate covered up to 12 hours before baking.
