Ingredients for arbys roast beef and cheddar cheese sandwich
Thinly sliced beef, perfectly toasted buns, and melty cheddar create that iconic Arby's experience at home.
| Ingredient | Amount | Notes |
|---|---|---|
| Top-Quality Roast Beef 🥩 | 1 ½ lb | Thinly sliced against the grain |
| Cheddar Cheese Slices 🧀 | 8 oz | American or sharp cheddar preferred |
| White Bread Loaves 🍞 | 2 whole | Crustless, soft texture ideal |
| Unsalted Butter 🧈 | 2 tbsp | For toasting bread slices |
| Mayonnaise 🥄 | ¼ cup | For spreading on beef |
| Yellow Mustard 🟡 | 2 tbsp | For sandwich assembly |
| Kosher Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Ground Black Pepper 🌶️ | ¼ tsp | Freshly ground for best flavor |
| Garlic Powder 🧄 | ¼ tsp | For beef seasoning |
| Onion Powder 🧅 | ¼ tsp | For beef seasoning |
| Vegetable Oil 🫒 | ½ cup | For beef slicing prep |
| Horsey Sauce 🍯 | 2 tbsp | Optional for serving |
The roast beef is non-negotiable for authenticity. Look for top-quality cuts like top round or sirloin—these slice thinly and stay tender when heated. Costco or Whole Foods carry excellent pre-sliced options, but if you're slicing yourself, freeze the beef for 30 minutes first to make it easier. The cheddar should be sharp or American-style—pre-shredded works, but block cheese melts more smoothly. For the bread, crustless white loaves from Sara Lee or Wonder Bread hold up best to toasting without burning. The secret here is keeping everything fresh: beef within 3-5 days of purchase, cheese unopened, and bread stored in the freezer until ready to toast.
No mayonnaise? Greek yogurt thinned with lemon juice works as a substitute—it adds creaminess without overpowering the beef. Short on cheddar? Swiss or provolone melts beautifully too, though the flavor profile shifts slightly. For the bread toasting, butter is ideal, but olive oil spray prevents burning if you're nervous about timing. The beef seasoning—just salt, pepper, garlic, and onion powder—is minimal but essential. Skip the pre-seasoned beef packets; those contain fillers that alter the texture. If you're making these ahead, assemble the sandwiches without cheese, wrap tightly in foil, and toast just before serving to maintain that crispy texture.
Beef slices should be kept in the fridge until ready to assemble—no need to thaw if pre-sliced. The bread stays freshest in the freezer; toast directly from frozen for maximum crispiness. Assembled sandwiches keep for 2-3 days in the fridge, but the texture degrades after the first day. For game day prep, slice the beef and store it separately, then assemble and toast just before serving. The cheese melts best when heated gently—toaster oven or griddle methods work better than microwave for that classic fast-food texture. Leftovers? Wrap tightly in foil and reheat in a skillet with a splash of water to revive the crisp.

Step-by-step instructions for recreating Arby's signature roast beef sandwich
Master the technique for perfectly sliced roast beef and toasted bread with melty cheese rivers.
Season and Slice the Roast Beef
Begin by slicing the 1.5 lb top-quality roast beef against the grain into ¼-inch thick slices. I use a sharp carving knife and the 0.5 cup vegetable oil to keep the blade gliding smoothly through the meat. This thin slicing ensures maximum tenderness and surface area for flavor absorption.
Transfer the sliced beef to a bowl and combine with 0.5 tsp kosher salt, 0.25 tsp ground black pepper, 0.25 tsp garlic powder, and 0.25 tsp onion powder. Gently toss until every slice is evenly coated. Let the seasoned beef rest for 10 minutes at room temperature before assembling—this allows the seasonings to penetrate and prevents uneven cooking when toasted.
Prepare the Cheese and Spread Mixture
Spread 0.25 cup mayonnaise evenly over each slice of beef. This creates a flavorful base that helps bind the sandwich components. Then layer 4 slices of cheddar cheese (about half the total 8 oz) on top of the mayonnaise-coated beef. I use sharp cheddar for its superior meltability and flavor intensity.
Next, spread 2 tbsp yellow mustard on one side of each slice from the 2 whole white bread loaves. The mustard adds tangy contrast that cuts through the richness of the beef and cheese. Keep the bread slices slightly off the cutting board during spreading to prevent sogginess.
Assemble and Toast the Sandwiches
Place the beef-cheese assembly onto the mustard-spread side of the bread. Top with the remaining bread slice, mustard-side down, creating a sealed sandwich. This assembly method prevents cheese from leaking during toasting while ensuring even browning.
Heat a non-stick skillet over medium heat and melt 1 tbsp unsalted butter until foaming. Add the assembled sandwiches and cook for 3-4 minutes per side until the bread develops golden brown toasted spots and the cheese begins to melt. Press down gently with a spatula during the first minute to ensure even contact with the pan—this prevents curling and guarantees crispy toasted bread.
Create Cheese Rivers and Serve
Once the sandwiches are golden and the cheese has melted to form rivers, transfer them to a cutting board. Let them rest for 2 minutes before serving. This brief rest allows the cheese to set slightly while maintaining its gooey rivers—critical for that Arby's signature texture.
Serve immediately with 2 tbsp Horsey Sauce on the side for dipping. The sauce should be thick enough to coat a spoon but still flow smoothly. Each bite should deliver perfectly toasted bread, tender beef, and melty cheese that holds together yet creates those signature rivers when cut.
Pro Tips For Making Arbys Roast Beef And Cheddar Cheese Sandwich
- TOAST BREAD UNTIL CRISP: This isn’t just about soft bread—get that toast golden and firm enough to hold up to the beef and cheese. I used to skimp on toasting, and the sandwiches turned soggy within minutes. Two minutes per side on medium-high, flipping once, guarantees structure.
- SLICE BEEF THIN OR FREEZE IT: Thinly sliced roast beef (⅛-inch thick) heats faster and stays tender, but if your butcher won’t slice it that way, freeze the beef for 20 minutes first. It’ll slice cleanly like a pro—no tearing or uneven pieces ruining your sandwich layers.
- BUTTER THE BREAD INSIDE OUT: Spread unsalted butter only on the outer bread slices, not the insides. The cheese and mayo will melt into the bread naturally, but butter on the insides makes the sandwich greasy and messy. Trust me, this small step keeps things tidy and delicious.
- CHEESE LAST MINUTE, COVER TIGHT: Add the cheddar slices right after the beef hits the bread—no pre-melting. Then slap on a lid or foil immediately to trap the steam. I learned this after watching my cheese turn rubbery; the heat from the beef melts it perfectly when sealed in.
Serving suggestions for leftovers
Classic Arby's Sides
Serve your roast beef and cheddar sandwich with Arby's signature curly fries—the crispy, golden exterior with a soft center. I recommend baking frozen fries from Ore-Ida Golden Crinkles at 425°F for 20-25 minutes for that perfect texture.
For a lighter option, swap in sweet potato fries tossed with smoked paprika and a sprinkle of sea salt before baking. 🍟
Fresh Crunch Additions
Add a crisp element with pickles—Arby's uses dill pickles for their tangy bite. Slice 4-5 spears and serve on the side. For extra freshness, include shredded iceberg lettuce or thinly sliced cucumbers to cut through the richness.
A simple lemon wedge on the side lets guests add brightness to each bite.
Horsey Sauce Variations
While Horsey Sauce is iconic, you can create homemade alternatives. Mix ¼ cup mayonnaise, 1 tbsp honey, 1 tbsp Dijon mustard, and ½ tsp garlic powder for a sweeter, tangier version.
For a spicy kick, add ½ tsp hot sauce or 1 tsp sriracha. Serve sauce in small shot glasses or mini ramekins for presentation. 🍯
Game Day Presentation
For football gatherings, arrange sandwiches on a large wooden board with toothpick flags for a casual, festive look. Pair with chips and dip (try guacamole or spinach-artichoke dip) and soda in glass bottles for that nostalgic diner feel.
Add mini American flags or team colors to plates for a fun touch. 🏈
Healthier Swaps
For a lighter version, use whole wheat buns toasted with olive oil spray instead of butter. Replace mayonnaise with Greek yogurt and swap cheddar for low-fat Swiss cheese. Serve with carrot sticks and hummus for extra fiber. These tweaks keep the flavor while cutting calories by 30-40%. 🥕
Dessert Pairings
End the meal with Arby's classic root beer floats—combine vanilla ice cream with A&W root beer for a creamy, fizzy treat. For a simpler option, serve chocolate chip cookies or brownies with a glass of milk.
A cinnamon sugar donut from a local bakery adds a nostalgic touch. 🍦

Frequently asked questions
Can I use pre-sliced deli roast beef for this recipe?
Yes, but with one key adjustment! Pre-sliced deli beef is often thinner than butcher-cut, so you may need 2 slices per sandwich instead of 1. Look for top round or sirloin cuts that haven't been pre-seasoned with heavy sodium. If the slices are very thin, layer them slightly overlapping for better texture.
Why does my cheese not melt into rivers like Arby's?
The secret is in the toasting method and cheese choice! Use sharp cheddar (not pre-shredded) and toast the sandwiches over medium heat for 3-4 minutes per side. The butter helps create steam that melts the cheese evenly. For extra rivers, press down gently with a spatula during the first minute of cooking.
How do I keep the bread from getting soggy?
Toast the bread just before assembling and use butter (not margarine) for toasting—it creates a crisp barrier. Assemble the sandwich immediately after toasting, and press down gently with a spatula during the first minute of cooking to seal the layers. Avoid spreading too much mayo on the beef.
Can I make these sandwiches ahead of time?
Yes, but with a key trick! Assemble the sandwiches without cheese, wrap tightly in foil, and refrigerate for up to 2 days. When ready to serve, toast in a skillet with butter and add the cheese during the final 1-2 minutes of cooking. This keeps the bread crispy while melting the cheese fresh.
What's the best way to reheat leftovers?
For maximum crispiness, use a skillet with butter over medium heat for 2-3 minutes per side. Add a splash of water to the pan to create steam, which helps revive the toasted texture. Microwaving will make the bread soggy—never do that with this sandwich!
