Roast Beef & Cheddar Sliders

Updated: Jul 11, 2022

Something you should know about me is I absolutely LOVE sliders aka tiny sandwiches. Given the option, I will take a few mini sandwiches over a full size sandwich any day of the week. Whether is a burger, grilled cheese, chicken sandwich, or a melty roast beef sandwich, I'll take the itty bitty option every single time. I just love having all the flavors and textures of a normal sized sandwich but in the palm of your hand and just a few bites to finish. To each their own, but I'm Team Tiny Sandwich from now until forever.

Regardless of where you fall in that camp, sliders are a great option when you're looking for easy party food that is filling and hearty. Everyone loves picking at the smorgasbord at parties, but it's the worst when you leave and still feel hungry because there wasn't enough meat, so to speak, to fill you up. That's why I love these sliders in particular.

They are so easy to pull together and it's easy to make a bunch of them for a big crowd. Instead of trying to construct tons of little sandwiches on an individual basis (can any say tedious??!), these are as easy as making one sandwich. And who doesn't love King's Hawaiian Rolls? I don't know about you, but I could eat an entire package of them on my own, no problem. In about 6 steps and just a few ingredients, you have these delicious little bites that are easy to serve and eat and that everyone will love. Whatever you do, DON'T skip the sauce that goes on top. It is was takes these over the edge. You can skip the poppyseeds if you'd like, but the brown sugar/butter/dijon is what sets these apart.

Make these for your next football party, Saturday get-together, or when the kiddos are having a slumber party. But be prepared, because everyone will be asking for these time and time again.

I recommend reading the recipe all the way through, including the recipe notes at the bottom, before you start cooking.


  • 1 package of King's Hawaiian Rolls original (~ 12 rolls in a pack)

  • 3/4 lb. thinly sliced deli roast beef (top round or London broil)

  • 6 slices cheddar cheese (normal slice, not thin slice)*

  • BBQ sauce (about 2 TB, but total amount is to taste)

  • 2 TB butter

  • 1 tsp. Dijon mustard

  • 1 tsp. brown sugar

  • Poppyseeds (optional)

  • Horseradish sauce (optional) I like Woeber's Sandwich Pal


  1. Preheat the oven to 375°

  2. Keeping the rolls attached to one another, cut them in half with a bread knife so you have the tops and bottoms of the rolls now separated. Place the bottom halves (still attached to one another) in the bottom of a baking dish. If desired, spread a little bit of the horseradish cause onto the cut side of the rolls in the dish and spread it around with the back of a spoon.

  3. Layer the roast beef across the roll bottoms in the pan, evenly distributing. Next, spread 1-2 TB of your favorite BBQ sauce over the roast beef using the back of a spoon.

  4. Layer the cheese over the roast beef then replace the tops of the buns to the sandwiches.

  5. In a small sauce pan (or in the microwave) over low heat, melt the butter then add the dijon mustard and brown sugar. Stir together until the sugar is completely dissolved into the butter then remove from heat.

  6. Using a pastry brush (or a spoon if you don't have one), spread the butter/brown sugar mixture all over the tops of the buns. Finish with a sprinkle of poppyseeds if desired.

  7. Loosely cover the sandwiches with foil to avoid burning and bake for 20-25 minutes at 375° or until the roast beef is hot and the cheese is melted and bubbly.

  8. Let rest for 5 minutes in the pan after removing from the oven, then transfer the sandwiches to a cutting board. Cut into individual sandwiches with a sharp knife and serve with extra bbq sauce and horseradish sauce.

  9. Store leftovers in a sealed container in the fridge and reheat in the microwave or covered in foil in the oven.

*Recipe notes + Variations*

*If you only have thinly sliced cheese, you may just want to use a few more slices of cheese to get a nice, cheesy covering over the roast beef.

When I reheat these, I prefer to do it in the toaster oven or oven, but I will zap them in the microwave for 20 seconds or so to help speed along warming the insides. This way they reheat a little quicker in the oven, but you also avoid burning or drying out the buns since they've already been baked once.
