Ingredients for arby's philly beef and swiss
Four sandwiches packed with smoky beef, melty Swiss, and that iconic Arby's sauce—ready in 30 minutes.
| Ingredient | Amount | Notes |
|---|---|---|
| Roast Beef 🥩 | 1 ½ lb | Thinly sliced against the grain |
| Swiss Cheese 🧀 | 8 oz | Thinly sliced, full-fat preferred |
| Hoagie Rolls 🍞 | 4 whole | Freshly baked or toasted |
| Mayonnaise 🥫 | ½ cup | For sauce base, Hellmann's preferred |
| Ketchup 🍅 | ¼ cup | For sauce tanginess |
| Worcestershire Sauce 🥘 | 1 tbsp | For umami depth |
| Yellow Mustard 🌶️ | 1 tbsp | For sharpness |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Onion Powder 🧅 | 1 tsp | For savory base |
| Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Olive Oil 🫒 | 1 tbsp | For beef marinade |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Butter 🧈 | 2 tbsp | Unsalted, for roll toasting |
| Pickles 🥒 | 4 slices | Optional, for tangy crunch |
The roast beef is everything. Look for pre-sliced roast beef at the deli counter—it's already thinly sliced against the grain, which is key for tender bites. If you can't find pre-sliced, grab a 1.5 lb roast beef and slice it yourself (or ask the butcher to do it). Kroger or Whole Foods usually have a good selection. The Swiss cheese should be full-fat—it melts better and gives that classic gooey texture. Skip the pre-shredded stuff; thinly slice it yourself for even melting. Hoagie rolls? Fresh is best—they toast up perfectly, but sub with any crusty roll if that's what you've got.
No Hellmann's mayo? Duke's or Best Foods work just as well—stick with a classic mayo for that signature tang. Short on Worcestershire? Substitute soy sauce at half the amount, but you'll lose some depth. The sauce is where the magic happens, so don't skimp on the ketchup—it balances the richness. For the beef marinade, olive oil and kosher salt are non-negotiable; they help tenderize and season the meat. If you're feeling fancy, add a splash of beef broth to the marinade for extra umami. And yes, pickles are optional, but they add that perfect tangy crunch that cuts through the richness.
The beef marinade keeps for 2 days in the fridge, but use it within 48 hours for best flavor. Swiss cheese stays fresh for 1 week wrapped in parchment, and hoagie rolls freeze beautifully for 3 months—just thaw and toast before assembling. Make the sauce ahead and store it in an airtight container for 5 days. Pro tip: Assemble the sandwiches fresh—the cheese melts best when everything's at room temperature. Leftovers? Wrap them in foil and reheat in a skillet for 2-3 minutes per side—just enough to melt the cheese without drying out the rolls.

Step-by-step instructions for Arby's-style philly beef and Swiss
Let's build this iconic sandwich with tender roast beef, gooey Swiss, and that perfect sauce balance.
Prepare the Signature Sauce
In a medium bowl, combine the 0.5 cup mayonnaise, 0.25 cup ketchup, 1 tbsp Worcestershire sauce, and 1 tbsp yellow mustard. Whisk until completely smooth and uniform in color. This sauce should have a rich, tangy-sweet balance that cuts through the richness of the beef and cheese.
Next, add the 1 tsp garlic powder, 1 tsp onion powder, and 0.5 tsp black pepper. Mix well until all the spices are fully incorporated. The sauce should have a subtle, savory depth that enhances every bite of your sandwich. Taste and adjust seasoning if needed—you can add a pinch more salt if desired, but the Worcestershire already provides plenty of umami.
Sear and Slice the Roast Beef
Heat the 1 tbsp olive oil in a large skillet over medium-high heat until shimmering. Season the 1.5 lb roast beef generously with 1.5 tsp salt and 0.25 tsp black pepper (reserving a bit for later). Sear the beef for 3-4 minutes per side, until it develops a deep brown crust and reaches medium-rare (about 130-135°F internally).
Remove the beef from the skillet and let it rest for 5 minutes before slicing thinly against the grain into ¼-inch strips. This resting period ensures the meat stays juicy, while slicing against the grain guarantees each bite is tender and easy to chew. The beef should be warm but not hot when you slice it—this makes handling easier and prevents it from drying out.
Assemble the Sandwiches
Toast the 4 whole hoagie rolls lightly with 2 tbsp butter in a separate skillet over medium heat for 1-2 minutes per side, until golden brown and crisp. This step adds a satisfying crunch that balances the softness of the beef and cheese. Let the rolls cool slightly before assembling.
Spread a generous 2 tablespoons of the prepared sauce on the bottom half of each roll. Layer ¼ of the sliced roast beef evenly across the roll, followed by 2 slices of Swiss cheese. Top with 1 slice of pickles (if using) and the remaining sauce. Place the top half of the roll on securely and press gently to help the cheese begin melting.
Melt the Cheese and Serve
To melt the cheese perfectly, heat a clean skillet over medium-low heat. Place the assembled sandwiches, sauce-side down, in the skillet and cook for 2-3 minutes per side until the Swiss cheese is fully melted and the bread is golden in spots. The cheese should be gooey and stretchy, creating that classic Arby's experience.
Press down gently with a spatula during the last 30 seconds of cooking to help the cheese adhere to the beef and bread. Remove from the skillet and let rest for 1 minute before serving. This brief rest allows the sandwich to hold together better, preventing any cheese from oozing out when you cut into it.
Cut and Enjoy Immediately
Slice each sandwich diagonally into two equal halves and serve immediately. The sandwich should have layers of tender roast beef, melted Swiss cheese, and crispy, buttery rolls, all held together by the rich, tangy sauce. Each bite should deliver a perfect balance of smoky beef, creamy cheese, and that signature Arby's flavor.
For the best experience, serve with a side of crispy fries or a cool, creamy coleslaw to complement the hearty sandwich. The combination of textures and flavors makes this a satisfying meal that's perfect for lunch or dinner.
Pro Tips For Making Arby'S Philly Beef And Swiss
- Slice Thin, Stack Tight: I learned this the hard way—thick roast beef slices won’t melt the Swiss properly and end up dry. Aim for ¼-inch slices (about 10 slices per sandwich) and layer them horizontally in the roll first, then add cheese on top. The weight of the beef will press the cheese into perfect gooeyness when grilled.
- Toast Rolls Low and Slow: Skip the high-heat blast—it burns the outside before the inside warms. Instead, toast hoagie rolls on medium-low heat for 2-3 minutes per side until golden but still soft. Over-toasted rolls turn into hockey pucks, and you’ll regret it when the first bite cracks like a twig.
- Prep Cheese Like Butter: Swiss cheese is finicky—if it’s too cold, it won’t melt smoothly. Cut it into ¼-inch strips (not chunks) and let them sit at room temp for 10 minutes before assembling. Cold cheese = clumpy mess; room-temp cheese = silky, stretchy perfection.
- Sauce in Layers, Not Drown: Dumping mayo and ketchup directly on the beef makes soggy sandwiches. Instead, spread a thin layer of mayo on the roll’s bottom half, then add ketchup only to the top slice of beef. This keeps the filling crisp and the flavors balanced—no one wants a greasy, saucy brick.
Essential equipment for this recipe
Skillet Essentials
Your 8-inch cast iron skillet is the MVP for this recipe—it retains heat perfectly and creates that signature caramelized crust on the beef. I recommend a Lodge cast iron (pre-seasoned) for even heat distribution. If you don’t own one, a stainless steel skillet works too, but monitor the heat closely to avoid hot spots. 🔥
For the sauce prep, grab a medium mixing bowl (glass or stainless steel) to combine ingredients smoothly. A whisk (preferably silicone-tipped) ensures no lumps in the mayo-ketchup blend. I keep my Hellmann’s mayo and Worcestershire sauce in small squeeze bottles for easy measuring—no messy spooning!
Cheese Melting Tools
To achieve that gooey Swiss cheese layer, use a spatula with a flexible edge (like a OXO Good Grips) to press down on the sandwiches during the final cooking stage. This helps the cheese adhere to the beef and bread. A clean, dry skillet is crucial—any moisture will steam the cheese instead of melting it properly.
For slicing the Swiss cheese, invest in a sharp chef’s knife (I love my Victorinox 8-inch) and a cutting board with a non-slip mat. Thin slices melt faster and more evenly than thick chunks. If you’re short on time, pre-slice the cheese while the beef rests—it only takes a minute!
Roll Toasting Setup
Toast your hoagie rolls in the same skillet you sear the beef (just clean it first!). Use 2 tablespoons of unsalted butter—it adds richness without overpowering the sandwich. A small offset spatula helps flip the rolls evenly. For extra crispiness, toast them 1-2 minutes per side until golden brown.
Pro tip: If your skillet is too small for the rolls, use a second small skillet or even a toaster oven set to 350°F for 2-3 minutes. Just watch closely to avoid burning. The rolls should be lightly toasted, not charred—this keeps the sandwich structure intact.
Assembly Station
Set up a clean workspace with all your components within reach: sliced beef, cheese, sauce, and toasted rolls. A small plate or tray helps organize the layers before assembly. I like to spread the sauce on the bottom half of the roll first, then add beef and cheese in even layers. This prevents cheese from oozing out during cooking.
For easy slicing later, use a serrated knife (like a Ginsu 8-inch) to cut the sandwiches diagonally. The serrations grip the crusty rolls better than a smooth blade. Serve immediately on a wooden board or platter for that classic diner vibe. 🍽️

Frequently asked questions
Can I use ground beef instead of roast beef for this sandwich?
While ground beef won't give you that classic Arby's texture, you can make it work! Use 80/20 ground beef (80% lean, 20% fat) for juiciness, and cook it until it reaches 160°F to ensure safety. For a closer match, shape the beef into thin patties and sear them quickly over high heat—just don't expect the same tender, sliced texture. The Swiss cheese will still melt beautifully!
How do I keep the hoagie rolls from getting soggy?
Toast the rolls just before assembling and keep them warm in a 200°F oven while you finish cooking the beef. For extra protection, brush the insides with a tiny bit of butter or olive oil before adding the filling. Assemble the sandwiches right before serving, and press down gently with a spatula during the final cooking step to help the cheese set faster.
What's the best way to reheat leftover sandwiches?
Wrap leftovers in foil and reheat in a skillet over medium-low heat for 2-3 minutes per side until the cheese melts. Avoid microwaving—it makes the rolls rubbery. For extra crispiness, toast the rolls separately in a dry skillet for 30 seconds per side after reheating. Store leftovers in an airtight container for up to 3 days in the fridge.
Can I make this sandwich ahead of time?
Prep everything except the final assembly up to 24 hours ahead: marinate the beef, make the sauce, and slice the cheese. Store components separately in the fridge. When ready to serve, toast the rolls, assemble the sandwiches, and cook them fresh. The cheese won't melt properly if pre-assembled, but this method keeps all elements fresh and ready for quick cooking.
What if I can't find Swiss cheese?
Emmental or Gruyère work beautifully as substitutes—they melt just as smoothly. For a milder flavor, try provolone, but it won't have the same classic taste. Avoid pre-shredded cheese (it contains anti-caking agents that prevent proper melting). If all you have is cheddar, thinly slice it and cook the sandwiches at a slightly lower heat to prevent burning.
