Ingredients for arby's philly beef and swiss
Thinly sliced beef, gooey Swiss, and perfectly toasted buns—here’s how to nail that Arby’s taste at home.
| Ingredient | Amount | Notes |
|---|---|---|
| Roast Beef (Top Round or Sirloin Tip) 🥩 | 1 ½ lb | Thinly sliced (1/8-inch thick), against grain |
| Swiss Cheese 🧀 | 8 oz | Sliced (1/4-inch thick), semi-soft |
| Arby's Style Toasted Buns 🍞 | 4 whole | Sesame seed buns, lightly toasted |
| Au Jus Mix 🍲 | ½ cup | Beef au jus packet (or homemade blend) |
| Butter 🧈 | 2 tbsp | Unsalted, for toasting buns |
| Olive Oil 🫒 | 1 tbsp | For searing beef |
| Garlic Powder 🧄 | 1 tsp | For beef seasoning |
| Onion Powder 🧅 | 1 tsp | For beef seasoning |
| Black Pepper 🌶️ | ½ tsp | Freshly ground for beef |
| Salt 🧂 | 1 tsp | Kosher salt for beef |
| Mayonnaise 🥫 | 2 tbsp | For spreading on buns (optional) |
| Mustard 🍯 | 1 tbsp | Dijon or yellow for spreading |
| Beef Broth 💧 | ¼ cup | For homemade au jus (if not using packet) |
| Worcestershire Sauce 🍶 | 1 tbsp | For homemade au jus |
| Brown Sugar 🍬 | 1 tbsp | For homemade au jus |
The beef is everything. Top round or sirloin tip cuts best for that signature texture—thinly sliced against the grain so it’s tender but holds up to toasting. Most grocery stores sell pre-sliced roast beef, but if you’re slicing yourself, ask the butcher for 1/8-inch slices. For the au jus, Arby’s packets are the easiest shortcut, but I make a quick homemade blend with beef broth, Worcestershire, and brown sugar. Pro tip: Toast the buns in butter—it’s what gives them that crispy, buttery edge.
No au jus packet? Mix 1/4 cup beef broth, 1 tbsp Worcestershire, and 1 tbsp brown sugar—simmer for 5 minutes to deepen the flavor. For the cheese, Swiss from the deli counter melts best (pre-sliced gets rubbery). Short on time? Skip the mayo—the beef and cheese are flavorful enough. The key is in the sear: high heat, 30 seconds per side for that caramelized crust without overcooking the inside. And if you’re feeling fancy, add a dash of smoked paprika to the beef seasoning for that extra smoky kick.
Beef stays fresh for 3 days in the fridge, but slice it fresh if possible. Toast the buns just before assembling—they go stale fast. The au jus keeps for 1 week in the fridge, so make extra for dipping. I always assemble sandwiches right before serving—the cheese melts best when everything’s hot. These reheat poorly, so make them fresh if you can. For leftovers, wrap tightly in foil and reheat in a skillet for 2 minutes per side.
Why You'll Love This Recipe
- No Fuss, Big Payoff: I swear by this recipe because it’s the kind of meal where you spend more time slicing the beef than anything else. That au jus mix? Just a splash, and suddenly you’ve got restaurant-quality depth without the fuss of homemade gravy.
- Creamy, Crisp, Perfect Bite: The Swiss melts into gooey perfection while the toasted bun stays crisp—honestly, that contrast is what makes it addictive. And the butter? A little dab on the bun before toasting makes all the difference.
- Lunchbox Hero: Between us, this is my go-to for meal prep. Slice the beef thin, stack it with cheese, and wrap it in foil—it holds up for days, and the au jus stays sticky and delicious. (Yes, even on a Tuesday night.)
- Budget-Friendly Feast: A pound of roast beef and a block of Swiss stretch farther than you’d think, especially when you’re feeding a crowd. I’ve made this for game day, potlucks, and even a lazy Sunday—it’s reliable, filling, and won’t break the bank.
Step-by-step instructions for Arby's-inspired philly beef and Swiss sandwiches
Here's how to recreate that iconic smoky, melty sandwich at home—layer by layer.
Sear and Slice the Roast Beef for Maximum Flavor
Pat the 1.5 lb roast beef dry with paper towels—this helps create that signature crust. Heat 1 tablespoon olive oil in a large skillet over medium-high heat until shimmering. Add the beef in a single layer and sear for 4-5 minutes per side until deeply browned and medium-rare (internal temp 130-135°F). The beef should release easily from the pan when ready.
Transfer the beef to a cutting board and let it rest for 10 minutes. While it rests, slice it against the grain into 1/8-inch thick strips. This cutting technique ensures tender, easy-to-eat bites. The beef should yield to your knife with minimal resistance—if it feels tough, let it rest another 5 minutes before slicing.
Prepare the Homemade Au Jus (If Not Using Packet)
In the same skillet (no need to clean it—the browned bits are flavor gold), reduce heat to medium and add 2 tablespoons butter. Let it melt completely, then add 1 tablespoon Worcestershire sauce, 1 tablespoon brown sugar, 1 teaspoon garlic powder, and 1 teaspoon onion powder. Stir for 1 minute until fragrant.
Pour in 1/4 cup beef broth and scrape up any browned bits from the bottom. Bring to a gentle simmer and cook for 3-4 minutes until slightly reduced and syrupy. Taste and adjust seasoning with 1 teaspoon salt and 1/2 teaspoon black pepper. If using the 1/2 cup au jus mix packet, dissolve it in 1/2 cup hot water instead. The au jus should coat the back of a spoon but remain pourable.
Toast the Buns and Assemble the Sandwiches
Lightly butter the cut sides of the 4 Arby's-style toasted buns with 2 tablespoons butter (about 1/2 tablespoon per bun). Toast them in a dry skillet over medium heat for 1-2 minutes per side until golden and crisp. The buns should be warm but not burnt—watch closely as they toast quickly.
Spread 2 tablespoons mayonnaise and 1 tablespoon mustard on the bottom half of each bun (about 1/2 tablespoon mayo and 1/4 tablespoon mustard per bun). Layer 1/4 of the sliced roast beef evenly across the bottom half, then top with 2 slices Swiss cheese (about 2 oz per sandwich). Drizzle 2 tablespoons au jus over each beef layer—just enough to lightly coat the beef without making it soggy.
Melt the Swiss and Final Assembly
Place the top half of the buns on the sandwiches and press down gently. Cover with a sheet of aluminum foil and microwave for 30-45 seconds on high. This step melts the Swiss cheese perfectly and binds the sandwich together. Alternatively, you can lightly toast the assembled sandwiches in a skillet over medium heat for 1-2 minutes per side until the cheese is fully melted and bubbly.
Let the sandwiches rest for 1 minute before serving. The cheese should be gooey and stretchy, the beef warm and tender, and the buns crisp yet soft. Cut each sandwich diagonally for that classic Arby's presentation. Serve immediately with any extra au jus on the side for dipping—it's where the magic happens!
Pro Tips For Making Arby'S Philly Beef And Swiss
- Slice Thin, Stack High: I learned this the hard way—thick slices of roast beef won’t caramelize properly in the pan, and you’ll end up with dry, chewy meat. Aim for ¼-inch slices, then layer them at least 3 inches high in the pan. The weight of the stack keeps the bottom slices juicy while the top gets that perfect sear.
- Butter the Bun Inside Too: That crispy, buttery crust on Arby’s buns isn’t just from toasting—it’s from buttering the inside of the split bun before assembling. Brush the cut sides with melted butter while the sandwich is cooking; it’ll steam slightly and give you that same toasted, buttery bite you crave.
- Skip the Overcrowded Pan: I used to load up the pan with all the beef at once, thinking it’d cook faster. Wrong. The meat steams instead of sears, and the au jus pools into a sad, watery mess. Cook in two batches if needed—hot pan, thin slices, and a little patience guarantee a crispy crust every time.
- Rest the Meat Under Foil: After pulling the beef from the pan, tent it loosely with foil and let it rest for 5 minutes. This keeps the slices from drying out while you melt the cheese and assemble. I know, I know—you want to eat it immediately. But trust me, the cheese will melt way better, and the sandwich won’t turn into a sad, greasy pile.
Perfect pairings for this dish
Side Dish Harmony
Start with crisp Arby's-style potato chips on the side—their salty crunch contrasts perfectly with the rich sandwich. I like Kettle Brand Sea Salt chips for that nostalgic Arby's flavor. For something fresh, pickle spears (like Heinz Sweet Gherkins) add a tangy bite that cuts through the beef's richness. 🍟
Classic Coleslaw Pairing
Nothing beats creamy coleslaw with this sandwich. My go-to is a mix of 1 cup shredded cabbage, 1/4 cup shredded carrots, and a dressing of 1/4 cup mayonnaise, 1 tbsp apple cider vinegar, 1 tsp sugar, and 1/2 tsp celery seed.
Toss it together and chill for 30 minutes before serving. The crunch and slight sweetness balance the savory beef beautifully.
Au Jus Dipping
Don't forget the au jus—it's the secret weapon! Serve it warm in a small ceramic dipping cup (like IKEA's 365+ line) so guests can dip their sandwiches.
For extra depth, add a dash of smoked paprika to the au jus before serving. The smoky, tangy flavor ties everything together. 🍲
Beer Pairings
A crisp American lager like Bud Light or Miller Lite is the classic choice—its light, clean finish won't overpower the sandwich. For something bolder, try a wheat beer like Blue Moon or a light IPA (like New Belgium Fat Tire) for a hoppy contrast.
Avoid heavy stouts or dark ales—they'll clash with the sandwich's delicate flavors.
Sweet Contrast
Balance the savory flavors with a sweet element. A few chocolate chip cookies (like Nabisco Chips Ahoy!) or a vanilla milkshake (made with Breyers Vanilla Ice Cream) add a nostalgic touch. For adults, a dark chocolate square (like Ghirardelli 72%) provides a sophisticated finish. 🍫

Frequently asked questions
What's the secret to getting that signature Arby's beef sear?
High heat and proper prep! Pat the beef completely dry before searing, then use medium-high heat in your skillet until it's shimmering. Sear for 4-5 minutes per side until deeply browned—this creates that signature caramelized crust while keeping the inside tender. Never skip the 10-minute rest before slicing either!
Can I use regular deli roast beef instead of buying a whole roast?
Yes, but with a caveat. Pre-sliced deli beef works in a pinch, but it's often too thin (1/16-inch instead of 1/8-inch) and lacks the proper texture. If using deli beef, slice it against the grain and layer two slices per sandwich to compensate. For best results, buy a whole roast and have your butcher slice it properly.
Why does my Swiss cheese get rubbery instead of gooey?
Two common mistakes: over-melting or wrong cheese type. Use semi-soft Swiss (not pre-shredded) and melt it just until bubbly—no longer. The key is assembling hot components: toast buns while beef is searing, then melt cheese quickly (microwave 30-45 seconds or skillet 1-2 minutes). Pre-shredded cheese has anti-caking agents that prevent proper melting.
How do I make this sandwich ahead of time?
Prepare components separately but assemble fresh. Sear and slice beef, make au jus, and toast buns—then store them separately. Reheat beef in a skillet for 1 minute, melt cheese in 20-second bursts in microwave, and toast buns again. The magic happens when everything's hot together. For leftovers, wrap tightly in foil and reheat in skillet for 2 minutes per side.
What's the best way to toast the buns without burning them?
Use a dry skillet over medium heat and watch closely—they toast quickly! Butter the cut sides first, then toast 1-2 minutes per side until golden. If using an oven, 350°F for 4-5 minutes works too. The key is even heat distribution—don't stack them or they'll steam instead of crisp.
