Ingredients You’ll Need

12 slider buns or small dinner rolls: These are essential for holding all the delicious fillings. Choose soft, fluffy buns for the best texture.
1 lb thinly sliced roast beef: Preferably cooked and warm. This is the star ingredient; you can use deli meat for convenience!
6 slices provolone or swiss cheese (cut in halves): These melt beautifully and add a creamy richness to the sliders. Feel free to substitute with cheddar for a sharper flavor.
2 tbsp butter, melted: Brushing the tops of the buns with butter gives them a delightful golden color and extra flavor.
1 tbsp olive oil: Used for sautéing the onions, it adds a touch of richness and depth to their flavor.
1 small onion, thinly sliced: Onions provide a sweet and savory element, especially when caramelized.
1 tsp garlic powder: This adds a warm, savory note that complements the beef perfectly.
1 tsp dried rosemary or fresh chopped rosemary: Rosemary brings a wonderful herbal richness; fresh is always best when available.
Salt and pepper, to taste: Essential for bringing all the flavors together.
Fresh parsley, chopped (for garnish): Adds a pop of color and fresh flavor to the finished sliders.
Optional: horseradish sauce or mayonnaise for spreading: A layer of tangy horseradish sauce or creamy mayonnaise can elevate the flavors even more!

How to Make Roast Beef Sliders

Sautéing the Onions: Begin by heating 1 tablespoon of olive oil in a skillet over medium heat. Once hot, add the thinly sliced onion, seasoning it with 1 teaspoon of garlic powder, 1 teaspoon of dried rosemary, and salt and pepper to taste. Stir the onions often, allowing them to cook for about 8-10 minutes until they turn soft and caramelized, becoming a lovely deep golden color.

Assembling the Sliders: Next, slice the 12 slider buns in half horizontally, arranging the bottom halves in a baking dish or on a sheet pan. Spread the flavorful caramelized onions evenly over the buns, creating a delicious bed for the meat. Layer the warm, thinly sliced roast beef evenly on top of the onions, and then crown your creation with the halved cheese slices, letting the cheese become an indulgent husband to the meat.

Baking and Serving: To finish, place the top halves of the buns back onto the sliders. Lightly brush the tops with the melted butter for that irresistible golden sheen. Cover the sliders loosely with aluminum foil and bake in your preheated oven at 350°F (175°C) for 10-12 minutes, until the cheese has melted and everything is warmed through. After that, remove the foil and bake for an additional 2-3 minutes to achieve a perfectly golden top. Before serving, garnish with fresh parsley for an inviting touch, and don’t forget to spread horseradish sauce or mayonnaise on the buns if you want an extra twist!

Storing & Reheating

To store your Roast Beef Sliders, keep them covered at room temperature for up to 2 hours. For longer periods, refrigerate in an airtight container for up to 3 days. You can also freeze sliders for up to 3 months; just make sure to wrap them tightly in plastic wrap before placing them in a freezer-safe bag. To reheat, simply place them on a baking sheet in a preheated oven at 350°F (175°C) for about 10 minutes until warmed through. Note that the texture may be slightly different after freezing and reheating, but you can refresh the sliders with a touch of melted butter on top as they warm.

Chef’s Helpful Tips

Be careful not to overcook the onions; they should be soft and lightly browned but not burnt for the best flavor.
Serve the sliders warm right out of the oven for the most satisfying experience and melty cheese.
If you’re using frozen roast beef, ensure it’s fully thawed and warmed to bring the best taste and texture.
Consider making the caramelized onions in advance; they can be stored in the fridge for up to 3 days!
For added flavor, consider mixing in some Worcestershire sauce with the roast beef before assembling.
