Easy Roast Beef Sliders Recipe

Looking for a recipe that will make the crowd at your next cookout or potluck super happy? These easy roast beef sliders are just the ticket. Made by layering Swiss cheese and roast beef on buttered slider buns, these sandwiches are baked until hot and melty. The result is a crowd-pleaser for sure.

Recipe developer Susan Olayinka of The Flexible Fridge opts to use Swiss cheese on these easy roast beef sliders, noting that "it has a great taste and it melts wonderfully." She loves serving them at a potluck alongside sides like roasted potatoes or crisps, but let your creativity be your guide when it comes to accompaniments. Coleslaw, baked onion rings, or watermelon are also great choices.

"Basically any food any finger food that you can get at a potluck!" she suggests. Two sliders per person should be enough for a portion, but guests with a big appetite — like Olayinka's husband! — may even opt for three!

To make these easy roast beef sliders, you'll start with a base of simple, store-bought buns. Use slider buns — the ones that come all partially attached — for their ease and for the best final result. 

To top the buns, you'll need melted butter, which you'll season with Italian seasoning for a delightful topping. Some Swiss cheese and deli roast beef — and a bit of cooking spray to grease the pan — and you're ready to begin. Parsley makes the perfect finishing touch!

To make these easy roast beef sliders, first preheat the oven to 350 degrees Fahrenheit. While the oven heats, slice the bread horizontally with a sharp knife, taking care to ensure that the buns all remain joined as you do. Next, spray the baking dish with nonstick spray, and place the bottom layer of the buns into it — this is where you'll build your sliders.

For super moist sliders, Olayinka brushes the buns with butter. Heat the butter in the microwave until fully melted, then brush on the buns in an even layer, saving some butter for the topping.

Next up, it's time to add the fillings! Top the buns first with the roast beef slices and then with the cheese, the combination of which gives these sliders a rubenesque flair. And not only that: Keeping the roast beef in the center, Olayinka explains, will prevent the meat from drying out in the oven.

"It is locked in between all of the layers of a sandwich so it's protected," she says. Close the sandwiches by adding the top layer of buns. Easy, right? Well ... we're not quite done yet!

Last but not least, before sending these easy roast beef sliders through the oven, brush the tops with melted butter and sprinkle with Italian seasoning, an herb blend that usually contains oregano, basil, thyme, rosemary, marjoram, parsley, and garlic. They're sure to suffuse your sliders with loads of flavor.

Now it's time to bake! Bake the sliders at 350 degrees Fahrenheit for 12 minutes, or until the cheese is nicely melted. Transfer to a serving plate, sprinkle with parsley, and dig in — either on their own or with a side of thousand island dressing or homemade hot mustard sauce for dipping.
