These Roast Beef and Cheddar Sliders are simply delicious and perfect for parties or family dinners! Soft rolls are filled with juicy roast beef and melty cheddar cheese, making each bite tasty.
I get so excited making these sliders! They’re super easy to whip up and always a hit. Plus, you can add a little horseradish for a fun kick if you’re feeling adventurous!
Key Ingredients & Substitutions
Slider Buns: Soft dinner rolls work best. If you’re not able to find slider buns, look for Hawaiian rolls or any soft white bread. Whole grain or gluten-free buns can be a good option too.
Roast Beef: Thinly sliced deli roast beef is perfect here. For a twist, use turkey or ham. You can even substitute leftover beef if you have it on hand!
Cheddar Cheese: I love sharp cheddar for its rich flavor. If you prefer something milder, try medium cheddar or even provolone. Dairy-free cheese options are available too!
Mustard & Worcestershire Sauce: Dijon adds great depth. If you’re out, yellow mustard or even barbecue sauce could work. Just adjust to your taste!
What’s the Best Way to Ensure Perfectly Melty Cheese?
Melting cheese on sliders needs a little bit of warmth and steam. Once you layer the cheese on top of the roast beef, covering the dish with foil traps moisture. This helps the cheese melt smoothly without drying out.
- Bake at 350°F (175°C), starting covered for about 15 minutes.
- After removing the foil, let it bake for an additional 5 minutes to crisp the buns and finish melting the cheese.
- Keep an eye on it to avoid over-baking; you want gooey cheese, not a dried-out slider!

Roast Beef And Cheddar Sliders
Ingredients:
For the Sliders:
- 12 slider buns or small dinner rolls, split
- 1 lb thinly sliced roast beef
- 12 slices of sharp cheddar cheese
For the Butter Mixture:
- 4 tablespoons unsalted butter, melted
- 1 tablespoon Dijon mustard
- 1 tablespoon Worcestershire sauce
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
Optional Toppings:
- Sesame seeds
- Dried onion flakes
- Chopped fresh chives or green onions for garnish
Time Needed:
Total time is about 30 minutes, with 10 minutes for prep and 20 minutes for baking. It’s a quick and easy solution for a delicious meal!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). This ensures your sliders cook evenly and the cheese melts perfectly.
2. Prepare the Slider Buns:
In a baking dish or rimmed sheet pan, arrange the bottom halves of your slider buns. Make sure they fit snugly together to keep the filling inside.
3. Layer the Roast Beef:
Evenly layer the thinly sliced roast beef over the bottom buns. Don’t be shy, add as much as you like for a hearty slider!
4. Add the Cheese:
Place one slice of cheddar cheese on top of the roast beef for each slider. This will melt beautifully during baking.
5. Top with the Buns:
Cover the beef and cheese layers with the top halves of the slider buns. Press down gently to secure everything together.
6. Make the Butter Mixture:
In a small bowl, combine the melted butter, Dijon mustard, Worcestershire sauce, garlic powder, and onion powder. Mix well until smooth and well blended.
7. Brush the Sliders:
Generously brush the butter mixture over the tops of the sliders. This will create a nice, flavorful crust and add moisture.
8. Add Optional Toppings:
If you’d like, sprinkle some sesame seeds and dried onion flakes over the top for extra flavor and crunch!
9. Cover and Bake:
Cover the baking dish tightly with aluminum foil. Bake for about 15 minutes, which allows the cheese to melt and buns to warm through.
10. Finish Baking:
After 15 minutes, remove the foil and bake for an additional 5 minutes, or until the tops are golden and slightly crisp. You’ll love how it smells!
11. Garnish:
Remove the sliders from the oven and, if desired, sprinkle some chopped chives or green onions on top for freshness and color.
12. Serve and Enjoy!
Now it’s time to dig in! Serve these warm and enjoy the delicious flavors of roast beef, melted cheddar, and buttery buns. Perfect for any gathering or just a cozy night in!
Can I Use Leftover Roast Beef for This Recipe?
Absolutely! Leftover roast beef works great in this recipe. Just make sure to slice it thinly so it layers well on the buns. You might want to warm it slightly before layering to ensure even heating while baking.
What Can I Substitute for Cheddar Cheese?
If cheddar isn’t your thing, feel free to use other cheeses like provolone, mozzarella, or even Swiss. Just remember that milder cheeses may not give the same flavor punch, so consider adding a little more seasoning to balance it out.
How Do I Store Leftover Sliders?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat them in the microwave or oven until warmed through. If you’re reheating in the oven, cover them with foil to keep the buns from becoming too hard.
Can I Make These Sliders Ahead of Time?
You can prepare the sliders in advance by assembling them without baking. Cover tightly and refrigerate for up to 24 hours, then bake them as directed. This is a great time-saver for parties!
