That roast beef is non-negotiable. Top round or sirloin tip works best—look for good marbling at Costco or Whole Foods. Slice it paper-thin against the grain (trust me on this). For the buns, Arby's-style potato buns are key, but Hawaiian Sweet Rolls from the bakery section work too. If you can't find them, any soft potato bun will do. The cheese? Sharp cheddar from a block melts like a dream—pre-shredded gets clumpy and won't give you those signature rivers.
No Arby's sauce? Mix ketchup with a splash of honey and a pinch of mustard—it's a solid copycat. Running short on panko? Regular breadcrumbs toasted in a dry pan work in a pinch. For the gluten-free version, grab gluten-free potato buns (check the freezer section at Target or Walmart). The beef seasoning is simple: salt, pepper, garlic powder, and onion powder. Don't skip the garlic powder—it's what makes Arby's beef taste so distinct. And if you're frying, use a deep fryer or heavy pot—vegetable oil stays hotter longer than other oils.
Keep the raw beef in the fridge for up to 3 days—use within 2 days for best texture. The buns stay fresh for 2 days if wrapped tightly, but I usually make these fresh. The sauce keeps for 1 month in the fridge, so batch it if you're making multiple sandwiches. These reheat beautifully—just 30 seconds in a skillet to get that crispy exterior back. Freeze extras for 1 month by wrapping tightly in foil.

Step-by-step instructions for Arby's-style roast beef sandwiches
Here's how to recreate that iconic crispy, cheesy Arby's experience at home.
Season and Slice the Roast Beef
Start by slicing the 1.5 lb top-quality roast beef thinly against the grain using a sharp carving knife. This ensures each slice stays tender and easy to bite. Place the sliced beef in a shallow dish and sprinkle evenly with 1 tsp salt, 0.5 tsp black pepper, 0.5 tsp garlic powder, and 0.5 tsp onion powder. Toss gently to coat all sides—this seasoning blend gives that signature Arby's flavor. Let the beef marinate for 10-15 minutes at room temperature while you prep the rest of your ingredients.
Pro tip: If you're using pre-sliced roast beef, skip the slicing step but still season it thoroughly. The key is even seasoning so every bite has that perfect balance of savory and slightly spicy notes.
Prepare the Buns for Frying
Split each of the 4 Arby's-style buns in half horizontally and place the bottom halves on a plate. Using a pastry brush, lightly butter both sides of each bun half with 1 tbsp butter (reserve the remaining 1 tbsp for later). This buttering step is crucial—it adds moisture and helps create that golden-brown crust when fried. While the butter is still soft, lightly dust both sides with 2 tbsp all-purpose flour, shaking off any excess. This creates a thin, crispy barrier that mimics the Arby's signature texture.
Keep the buttered, floured bun halves covered with a clean kitchen towel while you prepare the egg wash. The flour will help them hold their shape during frying, but don't press too hard or you'll end up with dense, gummy buns instead of light, crispy ones.
Create the Egg Wash and Panko Coating
In a shallow bowl, beat the 2 whole large eggs until just combined—no need to make them frothy, just lightly beaten so they coat a spoon evenly. In another shallow bowl, combine the 1 cup panko breadcrumbs with the remaining 2 tbsp all-purpose flour (if you used all the flour on the buns earlier, just use the panko alone). This mixture will give your sandwiches that signature crunchy exterior.
Dip each buttered bun half into the egg wash, letting any excess drip off, then immediately press into the panko mixture, coating both sides thoroughly. Place the coated bun halves on a wire rack set over a baking sheet to catch any stray crumbs. Repeat with all bun halves, working quickly so the egg doesn't dry out.
Fry the Buns to Golden Perfection
Heat 3 cups vegetable oil in a deep skillet or Dutch oven to 350°F—this is the perfect temperature for achieving that crispy yet not greasy texture. You'll know it's ready when a wooden chopstick inserted into the oil bubbles gently around the edges. Working in batches to avoid overcrowding, carefully place the panko-coated bun halves into the hot oil. Fry for 2-3 minutes per side until they're deep golden brown and crispy all over.
Use tongs to remove the fried buns and drain them on a paper towel-lined plate. The buns should be firm to the touch but still slightly pliable in the center. If they're browning too quickly, reduce the heat slightly to 325°F—you want that perfect balance of crispy outside and soft inside.
Assemble the Sandwiches with Melted Cheese
While the buns are still warm, spread 2 tbsp Arby's sauce on the bottom half of each bun. Layer 4 oz of the freshly shredded sharp cheddar cheese (about 2 oz per sandwich) on top of the sauce, then add 4 slices of the seasoned roast beef (about 6 oz per sandwich). Top with the fried bun halves and press gently but firmly to melt the cheese.
Here's where the magic happens: Let the sandwiches sit for 1-2 minutes so the cheese melts completely and creates those beautiful rivers of gooey goodness. The residual heat from the fried buns will finish melting the cheese just right. Serve immediately while everything is hot and crispy—these sandwiches are best enjoyed right away when the cheese is still molten and the buns are at their crispest.
Pro Tips For Making Arbys Roast Beef And Cheddar Cheese Sandwich
- Slice Thin, Stack Right: The roast beef’s magic isn’t in thick slabs—it’s in even, paper-thin slices. Use a sharp knife and cut against the grain (yes, even if it feels unnatural) for that signature tender bite. Stack three slices high for the classic Arby’s look, but if you’re lazy like me, two thick slices still hit the spot.
- Toast Buns Low and Slow: I learned this the hard way—blasting those buns in a screaming-hot pan burns the outside before the cheese melts. Instead, toast them on medium-low for 1-2 minutes per side until golden, then finish under the broiler for 30 seconds. The crust stays crisp without turning into charcoal.
- Shred Cheese, Don’t Melt It: Sharp cheddar’s the star, but dumping chunks on top just makes a sad, uneven mess. Grate it yourself (the finer, the better) and sprinkle it evenly between beef layers and on top. If you’re in a rush, pre-shredded works—but pulse it in a food processor to break up those anti-caking crystals.
- Press Hard, Hold Steady: That sandwich needs pressure to stick. After assembling, slap a heavy skillet or even a cast-iron pan on top for 1-2 minutes—no peeking! The weight melts the cheese into a cohesive glue, not a runny disaster. (Pro move: Wrap the whole thing in foil first if you’re making a batch ahead.)
Make-ahead tips for this arbys roast beef and cheddar cheese sandwich
Prep Ahead Components
Slice the 1.5 lb roast beef and season it up to 3 days ahead, storing it in an airtight container in the fridge. I like to do this the night before so it's ready for quick assembly.
The seasoning blend (salt, pepper, garlic powder, and onion powder) will penetrate the meat overnight, enhancing flavor without overpowering it. 🥩
Fry Buns Early
Fry the bun halves 1 day ahead and store them at room temperature in a single layer on a wire rack. This keeps them crispy rather than soggy.
Reheat in a 350°F oven for 3-5 minutes before assembling—just enough to restore that golden crunch. I often make a double batch for sandwiches and sliders.
Cheese Prep Shortcut
Shred the 8 oz sharp cheddar and store it in a sealed container for up to 5 days. Freshly shredded cheese melts better than pre-shredded, which contains anti-caking agents that prevent proper melting.
Keep it in the fridge until ready to assemble—cold cheese melts more evenly and creates those signature rivers. 🧀
Sauce Batch Prep
Make a large batch of Arby's sauce (or your copycat version) and store it in the fridge for up to 1 month. I triple the recipe and keep it in a mason jar for easy spreading.
The sauce thickens slightly when refrigerated, so give it a quick stir before using. This is my favorite make-ahead component because it's used in every bite.
Freezer-Friendly Assembly
For ultimate convenience, assemble the sandwiches without the top buns and freeze them on a tray for 2 hours. Then transfer to a freezer bag for up to 1 month.
To serve, thaw in the fridge overnight, add the fried top bun, and reheat in a 375°F oven for 5-7 minutes to melt the cheese. The texture stays crispy and the cheese remains gooey.
Reheating Perfection
For the best results, reheat fully assembled sandwiches in a skillet over medium heat for 2-3 minutes per side until the buns are crispy again. Add a splash of water to the pan to create steam, which helps melt the cheese evenly.
I avoid microwaving because it makes the buns rubbery—this skillet method brings back that fresh-from-fryer crunch. ✨

Frequently asked questions
Can I use regular hamburger buns instead of Arby's-style potato buns?
While it's possible, you'll miss the signature texture that makes this sandwich special. Arby's potato buns are designed to hold up to frying while staying soft inside. If you must substitute, look for soft potato rolls from the bakery section—they'll give you the closest result. Regular hamburger buns tend to get too soft and can make the sandwich soggy.
How do I get the cheese to melt into rivers like Arby's?
The secret is using sharp cheddar cheese from a block that's freshly shredded, not pre-shredded. Pre-shredded cheese contains anti-caking agents that prevent proper melting. Also, make sure your cheese is cold when you add it—this helps it melt more evenly. The residual heat from the fried buns will finish melting it just right while creating those signature rivers.
Can I bake the sandwiches instead of frying for a healthier option?
You can try, but you'll sacrifice that signature crispy texture. For a baked version, place assembled sandwiches on a baking sheet and bake at 375°F for 8-10 minutes until the cheese melts. While healthier, they won't have that crispy exterior. If you want crispiness, try air-frying at 375°F for 3-4 minutes—it's a compromise that still gives good results.
What's the best way to store leftover sandwiches?
Store them in an airtight container in the fridge for up to 3 days. To reheat, wrap them in foil and warm in a 350°F oven for 5-7 minutes or use a skillet over medium heat for 2-3 minutes per side. Avoid microwaving—they'll lose their crispy texture. For longer storage, freeze assembled sandwiches (without the top bun) for up to 1 month.
Can I make this sandwich gluten-free?
Use gluten-free potato buns (available at most grocery stores) and ensure your panko breadcrumbs are certified gluten-free. The roast beef and cheese are naturally gluten-free, so the only adjustments needed are the bun and breading. Just be sure to check labels on all ingredients to avoid cross-contamination.
