Cheesy roast beef sliders are about to become your new favorite game-day snack. Topped with caramelized onions, a tangy sauce, and plenty of cheese, these sliders are an at-home version of your favorite fast food roast beef sandwich.
I might not be much of a football fan, but I am a fan of football food.
Sliders are one of my favorite things to make for game days or for easy dinners. They’re quick and easy to throw together, there are a ton of variations you can make, and they’re always a hit.
My newest favorite version? These cheesy roast beef sliders. If you love those fast-food beef and cheddar sandwiches, then you’re gonna go nuts for this recipe.
COPYCAT BEEF & CHEDDAR SLIDERS
I love a fancy meal as much as anyone, but sometimes I crave some fast food “guilty pleasures.” One of those is an Arby’s beef and cheddar sandwich.
Is it “good”? Not really. Do I still love it every now and then? I sure do.
When I decided to take that craving and turn it into some cheesy roast beef sliders, I knew it would be a winner.
This recipe has all of the flavors of that fast-food favorite but in a made-at-home slider form.
There’s the thinly sliced roast beef, the tangy barbecue sauce, and of course the melty cheese. And since you can’t really find slider versions of onion buns, I even added some caramelized onions to the sliders.
These sliders are so snackable, they’ll disappear in no time!
HOW TO MAKE THESE CHEESY ROAST BEEF SLIDERS
Ingredients you’ll need
These cheesy roast beef sliders use just a handful of ingredients. This recipe even includes an optional homemade copycat Arby’s sauce.
For the sliders themselves, you will need:
- Caramelized onions: olive oil, yellow onion, pinch of sea salt
- King’s Hawaiian rolls
- Cheez Whiz
- Deli-sliced roast beef
- Shredded cheddar cheese
- Arby’s sauce
If you’re able to find onion bun-style slider rolls, feel free to use those and skip the caramelized onions if you like.
I can feel that look you’re giving me about the Cheez Whiz. I know it’s not “real” cheese, but I like combining it with the shredded cheddar cheese to give these sliders the same melty cheesy bite of the original sandwich.
If you’re really opposed to using Cheez Whiz, that’s fine – you can just use a bit more shredded cheddar cheese. Just keep in mind that the sliders will be missing that melty cheese sauce texture.
Some grocery stores carry bottled Arby’s sauce. If you can find it, feel free to use that on these sliders. If not, you can make your own tangy copycat using:
- Apple cider vinegar
- Tabasco or similar hot sauce
- Brown sugar
- Onion powder
- Garlic powder
- Salt & pepper
Making this recipe
Start by caramelizing the onion. Peel and thinly slice the onion, then add it to a skillet with olive oil and a pinch of salt over medium heat.
Cook the onion, stirring every few minutes, until it is caramelized. This will take about 30-40 minutes. You can learn more in my post on how to caramelize onions.
While the onion cooks, spray a 9×13-inch baking dish or a rimmed baking sheet with nonstick spray. Cut the rolls in half horizontally (like a bagel) using a serrated knife. Place the bottoms of the rolls in the prepared dish.
If you’re making your own sauce, combine all of the sauce ingredients in a sauce pot. Bring the mixture to a simmer, whisking occasionally. Warm the sauce through, then remove from the heat.
Spread the Cheez Whiz across the cut sides of the rolls, making sure to spread it across the tops and bottoms. Distribute the roast beef across the bottoms of the rolls, then top with the caramelized onions.
Spoon the sauce evenly over the onions, using as much as you desire. You can always save any extra for dipping or for guests to add to their sliders later.
Sprinkle on the shredded cheddar cheese and add the roll tops.
Bake the cheesy roast beef sliders for about 10-15 minutes. You want the cheese to be melted, the tops to be golden, and the sliders to be warmed through.
MAKE-AHEAD & REHEATING TIPS
If you’re making these cheesy roast beef sliders for a party, you can definitely prep them ahead of time.
You can caramelize the onions up to 3 days ahead; store them in an airtight container in the refrigerator until you’re ready to assemble the sliders.
You can also make the copycat Arby’s sauce up to 3 days ahead of time and store it in an airtight container in the refrigerator.
You could assemble the sliders up to the night before you plan to serve them and keep them covered in the refrigerator. I would wait to add the Arby’s sauce until just before putting them in the oven. This will help prevent the rolls from getting soggy from the sauce.
When you’re ready to go, bake them for a few extra minutes, as needed, if starting from cold.
How to reheat
If you have leftover cheesy roast beef sliders, store them in the refrigerator for up to 2 days. To reheat, wrap them in foil and place them in a 350°F oven for about 10 minutes or in a 350°F air fryer for about 5 minutes.
