This Arby’s roast beef and cheddar cheese sandwich recipe delivers the iconic fast-food experience at home—crispy toasted buns, tender roast beef, and rivers of melted cheddar that make every bite irresistible.
The secret lies in proper layering and a quick grill or pan toast to achieve that signature crunch without sacrificing the gooey cheese pull. I’ve perfected this version after years of recreating the classic, ensuring the beef stays juicy and the cheese melts just enough to create those signature rivers.
The key to nailing this sandwich is using thinly sliced roast beef (about 1/8-inch thick) and a high-quality cheddar that melts smoothly. You’ll also need a sturdy bun that can handle toasting without getting soggy—Arby’s-style sesame buns work perfectly, but any soft hamburger bun will do.
The assembly order matters: cheese goes on first, followed by beef, then pickles and onions, all pressed together before toasting to keep everything intact.
What you’ll end up with is a sandwich that tastes just like the original—crispy edges on the toasted bun, tender beef that’s been perfectly seasoned, and melted cheddar oozing out with every bite.
The pickles add a tangy contrast, while the onions bring a sharp crunch. This is the kind of sandwich that disappears in minutes, leaving you craving another.
For extra authenticity, serve with Arby’s-style curly fries or a side of their signature sauce. The recipe scales easily, so you can make a full batch for game day or meal prep sandwiches for the week. Let’s get started—your taste buds will thank you.
Ingredients for arbys roast beef and cheddar cheese sandwich
Four ingredients make this iconic sandwich—plus a few secrets for that perfect toasted crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Roast Beef 🥩 | 1 ½ lb | Thinly sliced (about 1/8-inch thick), deli-style |
| Sharp Cheddar Cheese 🧀 | 8 oz | Block cheese, freshly grated (not pre-shredded) |
| Sesame Seed Buns 🍞 | 4 whole | Arby’s-style or soft hamburger buns |
| Dill Pickle Slices 🥒 | ½ cup | Thinly sliced, about 10 slices |
| Red Onion Slices 🧅 | ¼ cup | Thinly sliced, about 4 slices |
| Unsalted Butter 🧈 | 2 tbsp | For toasting buns (or olive oil) |
| Mayonnaise 🍳 | 2 tbsp | For spreading on buns (optional) |
| Yellow Mustard 🌶️ | 1 tbsp | For spreading on buns (optional) |
| Salt 🧂 | ½ tsp | Kosher or sea salt (for beef seasoning) |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground (for beef seasoning) |
| Garlic Powder 🧄 | ¼ tsp | For beef seasoning (optional) |
The roast beef is non-negotiable here. Deli-style thin slices are ideal, but if you're buying a whole roast, slice it yourself—about 1/8-inch thick. I grab mine from Boar’s Head at the grocery store, but any high-quality roast beef works. Season it lightly with salt, pepper, and a pinch of garlic powder (trust me, it elevates the flavor). For the cheese, block cheddar is a must—pre-shredded gets clumpy and lacks that signature melt. Grab a wedge from the deli counter if you can, or grate your own from a block. The buns? Arby’s-style sesame buns are perfect, but any soft hamburger bun will do—just make sure they’re sturdy enough to handle toasting without falling apart.
No sesame buns? Substitute with brioche or potato buns—they hold up better to toasting. Short on pickles? Dill pickle juice mixed with a pinch of sugar works in a pinch (though nothing beats the real thing). The cheese can be swapped for Monterey Jack if you prefer a milder melt, but cheddar is the star here. For the beef, if you can’t find thinly sliced, pound a thicker cut to even thickness before slicing. And if you’re feeling fancy, add a dash of Worcestershire sauce to the beef for extra umami—it’s a game-changer. The key to assembly? Cheese first, beef second, then pickles and onions. Press it all together before toasting so nothing slips out.
Beef stays best in the fridge for 3-4 days once sliced, but it’s even better the next day after the flavors meld. Cheese keeps for weeks if wrapped tightly in parchment, and buns freeze beautifully—just thaw them at room temp before assembling. For meal prep, build the sandwiches without toasting and wrap them in foil. Toast them fresh when ready to eat—30 seconds in a hot pan with butter is all it takes for that perfect crunch. Leftovers? Reheat in a toaster or skillet until the cheese melts again. These sandwiches are best eaten the day they’re made, but they’ll still taste amazing for 2-3 days in the fridge.

Step-by-step instructions for Arby’s-style roast beef sandwiches
Here's how to recreate that iconic toasted bun and melted cheese experience at home.
Season and Sear the Roast Beef
Start by laying out the 1.5 lb roast beef on a clean cutting board. I like to slice it against the grain into ¼-inch thick strips—this ensures tender bites every time. In a small bowl, mix together the ½ teaspoon salt, ¼ teaspoon black pepper, and ¼ teaspoon garlic powder. Sprinkle this evenly over the beef and massage it in gently with your fingers so it sticks.
Heat a large skillet over medium-high heat and add the beef in a single layer. Let it sear undisturbed for 2-3 minutes until it develops a deep brown crust on one side. Flip carefully and cook for another 2-3 minutes until it reaches 140°F internally. Remove from the pan and set aside—it'll continue cooking slightly as it rests. The beef should be warm but still slightly pink in the center, not fully cooked through.
Prepare the Cheese and Toast the Buns
While the beef rests, take the 8 oz sharp cheddar cheese and freshly grate it using a box grater. I prefer block cheese over pre-shredded because it melts more smoothly. Set aside 6 oz of the grated cheese for the sandwiches and keep the remaining 2 oz for topping later.
In a separate skillet, melt the 2 tablespoons unsalted butter over medium heat. Add the 4 whole sesame seed buns cut in half and toast them for 1-2 minutes per side until they're golden brown and crispy. Here's the thing—you want that perfect Arby's-style crunch, so don't rush this step. The butter should bubble gently and the buns should develop a nice toasted color. Remove the buns and set them on a wire rack to cool slightly.
Assemble the Sandwiches with Perfect Layers
Spread ½ tablespoon mayonnaise and ½ tablespoon yellow mustard on each bun half—this is optional but adds that classic Arby's tang. Layer ¼ cup dill pickle slices and 1 tablespoon red onion slices on the bottom bun half. Then add ¼ of the seared roast beef and 1½ ounces of the freshly grated sharp cheddar cheese.
Here's where the magic happens: Top with another ¼ cup dill pickle slices and 1 tablespoon red onion slices, then add the remaining beef and cheese. Press down gently but not too hard—you want the cheese to melt and create those beautiful rivers when you cut into it later. Place the top bun on and press down lightly again to help the cheese start melting.
Melt the Cheese and Finish
Return the assembled sandwiches to the same skillet you used for toasting (no need to clean it—the beef juices add flavor) over medium-low heat. Cover with a lid and let them cook for 2-3 minutes until the cheese begins to melt and bubble. Here's what to watch for: the cheese should turn from solid to gooey, with those golden rivers forming between the slices of beef.
Once the cheese is fully melted and the buns are heated through, carefully transfer the sandwiches to a cutting board. Let them rest for 1 minute before serving—this helps everything hold together better. Top each sandwich with the remaining ½ ounce of grated cheese and serve immediately while the buns are still warm and crispy.
Pro Tips For Making Arbys Roast Beef And Cheddar Cheese Sandwich
- Sear the Beef First: I used to just slice and pile that roast beef, but searing the slices in a dry pan for 30 seconds per side—high heat, no oil—gives you a crust that holds up better when stacked. The cheese melts into that crispy edge like it’s supposed to, and the sandwich doesn’t turn into a sad, soggy mess halfway through.
- Toast the Buns Properly: Skip the sad, limp buns by toasting them in a skillet over medium heat for 30 seconds per side until they’re golden and slightly crisp. If you’re lazy and just microwave them, you’ll regret it when the first bite feels like chewing on a wet paper towel—especially with all that melted cheddar waiting to pool inside.
- Slice the Onions Thin: Thick onion slices scream "home cook shortcut," but thinly sliced red onions—almost translucent—add the right sharpness without overpowering the beef and cheese. Use a mandoline if you’re impatient, or just go for it with a sharp knife and take your time. The crunch and bite make a real difference when they’re done right.
- Layer Cheese Last: Pile the beef and onions first, then add the pickles, and only then slap on the cheddar. If you layer the cheese early, it’ll start melting into a greasy puddle before you even close the sandwich, and you’ll end up with a gloppy, uneven mess. Trust me, the first time I ignored this, I had to start over.
Make-ahead tips for this arbys roast beef and cheddar cheese sandwich
Prep Ahead Components
Slice the 1.5 lb roast beef into ¼-inch thick strips and season with salt, pepper, and garlic powder. Store in an airtight container for up to 3 days in the fridge.
I like to sear the beef ahead of time and refrigerate it—just reheat in a skillet for 30 seconds before assembling.
The cheese can be grated and stored in a sealed container for 5 days, while the buns stay fresh for 2 days at room temperature or 1 month frozen. 🧈
Assemble Untoasted
Build the sandwiches without toasting the buns—layer cheese, beef, pickles, and onions between the buns. Wrap them individually in foil and refrigerate for up to 24 hours. When ready to eat, toast in a buttered skillet for 1-2 minutes per side until golden.
This method keeps everything intact and makes for quick lunches. I do this for game day prep to save time during the big event.
Freezer-Friendly
Assembled sandwiches freeze beautifully for up to 1 month. Wrap each one tightly in foil, then place in a freezer bag with parchment paper between layers to prevent sticking. To reheat, bake at 350°F for 10-12 minutes or microwave for 1-2 minutes until the cheese is fully melted.
The texture won't be as crispy as fresh, but it's still delicious for a quick meal. 🥪
Cheese Melting Hack
For extra gooey cheese, sprinkle a pinch of cornstarch (about ¼ tsp) over the grated cheddar before assembling. This trick makes the cheese melt more smoothly and creates those signature rivers when toasted.
I discovered this while testing variations—it’s a game-changer for the perfect Arby’s experience at home. Keep the extra cheese in the freezer for quick sandwich assembly later.
Game Day Strategy
Prep all components the night before: slice beef, grate cheese, and toast buns. Store everything separately in airtight containers. On game day, assemble and toast sandwiches in batches while watching the game.
This keeps the kitchen clean and lets you enjoy the party without cooking stress. I’ve used this method for Super Bowls and tailgates—it’s a lifesaver. 🏈

Frequently asked questions
Can I use pre-shredded cheddar instead of block cheese?
Pre-shredded cheese works in a pinch, but it won't melt as smoothly or create those signature rivers. The anti-caking agents in pre-shredded cheese make it more likely to clump and separate. For the authentic Arby's experience, always use freshly grated block cheddar—it's worth the extra effort!
How do I keep the sandwich from falling apart when toasting?
Press the sandwich together firmly before toasting and use a sturdy bun that can handle the weight. For extra stability, lightly toast the buns first, then assemble with cheese and beef in between. The key is to press gently but firmly while toasting to help everything meld together. A quick assembly trick: place the sandwich on a plate and press down with a second plate while toasting.
What's the best way to reheat leftover sandwiches?
For best results, reheat in a skillet over medium heat for 1-2 minutes per side until the cheese melts and the bun crisps up again. If using a microwave, cover with a damp paper towel and heat for 20-30 seconds—just enough to warm through without drying out. The skillet method gives you that perfect toasted crunch you can't get from the microwave.
Can I make this sandwich gluten-free?
Use gluten-free buns and check that your roast beef and cheese are certified gluten-free. For the pickles and onions, verify they're processed in a gluten-free facility. The recipe itself is naturally gluten-free except for the bun—just make sure all your ingredients meet the requirements. Many gluten-free buns now mimic the texture of sesame buns quite well.
Why does my cheese not melt into rivers like Arby's?
This usually happens when the cheese isn't hot enough or the sandwich isn't pressed tightly enough during toasting. Use freshly grated block cheese and make sure your skillet is properly heated. The beef should be warm (not cold) when assembling, and you need to press the sandwich firmly while toasting. For extra gooey results, sprinkle a pinch of cornstarch on the cheese before assembling.
