Caramelized tangy onions and melty cheese top these easy to make Roast Beef Sliders for any game day party that will have everyone coming back for more! Perfect for entertaining a crowd without a lot of work!
We have lots of slider recipes you might enjoy such as the Kalua Pork Sliders and the spicy beef brisket sliders— be sure and check them out!
Nothing beats a bite-sized sandwich for game day appetizers like these Roast Beef sliders! They use Kings Hawaiian Rolls and you add all sorts of delicious flavors to create a bite-sized snack for any game day party.
They work great for Super Bowl Party Sandwiches, a snack at work, or after school too. You can make them ahead and serve them at room temperature (although honestly, I prefer them warm just out of the oven so the cheese is really melty and the juices of the buttery sauce is still slathering everywhere!)

How to make these Roast Beef Sliders?
- Buy a package of rolls that are tear apart like these Kings Hawaiian rolls or these Sara Lee Dinner Rolls. You’ll leave them as a super pack of rolls until you’ve prepared them so they are easier to assemble. (See how to cut the rolls in half in bulk at these Ham and Cheese Hawaiian Roll Sliders!)
- Slowly cook the onions in a little butter so they brown slowly and don’t burn, yet still have lots of juices to give to the slider. You’ll then layer everything on top of that one at a time, roast beef, cheese, then the onions. You can do it a couple of times if you want a really packed full Roast Beef Slider.
- Next, you make a jam-packed flavor sauce to brush inside and on top of the sandwiches. Every bite will be slathered in this marinade and it’s finger-licking good!
- I added a little rum, sugar, mustard and Worcestershire to the butter so it’s balanced, smoky, sweet and tangy! (The Rum is totally optional!)
- Then you will bake them covered for 15-20 minutes and then remove the foil and bake for an additional 5 minutes. See how they are all baked as one before serving. You don’t cut up the party sandwiches until you’ve baked them.
- It saves you loads of time since you are making in bulk versus one at a time!
These Roast Beef Sliders come together so quickly you won’t be using them just for Super Bowl Entertaining, you’ll be making them for snacks for after work or as a quick appetizer for when people drop by!
If you want to have a zest sauce on the side you can use this Carolina Mustard BBQ Sauce. It’s zesty, tangy and adds a nice twist to the sliders!

Roast Beef Sliders with Caramelized Onions
Caramelized tangy onions and melty cheese top these easy to make Roast Beef Sliders for any game day party that will have everyone coming back for more! Nothing beats a bite-sized snack for Super Bowl Party Food like these Roast Beef sliders!
Ingredients
- 24 dinner rolls, see post for links to kinds I recommend
- 1 pound deli roast beef
- 12 slices American or Swiss cheese
- 1 large onion, sliced thinly
- 2 Tablespoons butter
- 1 stick butter, 8-ounce stick
- 3 tablespoons rum
- 1 tablespoon dijon mustard
- 1 tablespoon brown sugar
- 1 tablespoon Worcestershire sauce
Instructions
- Preheat oven to 350°
- In a skillet heated to medium, melt the 2 tablespoons butter. Then add the onions and cook on low for about 10 minutes until golden brown and caramelized. Remove from heat to assemble sandwiches.
- Cut the entire 24 roll package of rolls in half so that the bun top is on one side and the bottoms on the other.
- Onto the bottom half, layer the roast beef, then cheese, then spoon caramelized onions evenly over the top of that. You may want to use a spoon in case the onions are too warm to handle.
- If you are making the sandwiches ahead of time, make until this step and place in fridge until you are ready to bake. Remove from fridge at the time you preheat your oven and make the butter mixture as stated below.
- In a microwave safe bowl, melt the butter for 30 seconds at a time until completely melted. Then add rum, sugar, Worcestershire and mustard and stir well. You will stir until the sugar is completely dissolved into the butter.
- Spread about half of the butter mixture on the inside of the bun tops. Place bun top over the bottom section and place it into a baking dish. Brush the remaining butter mixture over the top and sides of the sliders in the baking dish.
