Arby's Beef and Cheddar at Home Recipe: Crispy Roast Beef and Gooey Cheese Layers

This Arby's beef and cheddar at home recipe delivers the same crispy, slow-cooked roast beef and melty cheddar layers you crave—right in your own kitchen. The secret lies in a low-and-slow cooking method that transforms tough beef into tender, flavorful slices with just the right amount of char.

I've perfected this version after years of experimenting, ensuring every bite mimics the iconic sandwich while keeping prep manageable for home cooks.

The foundation starts with a simple seasoning blend of salt, pepper, and garlic powder, then slow-roasting the beef until it's fork-tender with a slightly crispy exterior. While the beef rests, you'll prepare a tangy sauce that cuts through the richness—just like Arby's signature horseradish kick.

The real magic happens when you layer that beef with melted cheddar between toasted buns, creating the perfect balance of textures and flavors.

What you'll end up with is a sandwich that's restaurant-quality at home: crispy, juicy beef with gooey cheese oozing at every bite, all held together by that signature tangy sauce. The aroma alone will have everyone gathering around your table, and the first bite will have them asking for seconds.

This isn't just a copycat recipe—it's a foolproof method that delivers consistent results every time.

Pair it with classic Arby's sides like crispy fries or creamy coleslaw for the full experience. The best part? You can make the beef ahead of time and assemble the sandwiches fresh, making this the perfect meal for game day, parties, or whenever that Arby's craving hits.

Ingredients for arby's beef and cheddar at home

Eight essential ingredients transform into crispy roast beef and gooey cheddar layers—just like Arby's!

The beef is everything—chuck roast from the butcher counter (not pre-cut) gives that signature tenderness. Costco or Walmart usually have it in bulk, but check the marbling—fat equals flavor. If you can't find chuck, top round works in a pinch, but it's leaner so don't skip the potato starch coating. The cheddar? Sharp, block-form only—pre-shredded has anti-caking agents that prevent melting. I grab mine from Trader Joe's when it's on sale, but any good grocery store carries it. Pro tip: Let the beef sit at room temp for 30 minutes before cooking for even browning.

No potato starch? Cornstarch or arrowroot powder at the same amount works perfectly. The sauce is where the magic happens—Dijon mustard adds depth, while the horseradish gives that signature kick. Short on mayo? Greek yogurt thinned with a splash of milk keeps it tangy. The sesame seed buns? Toast them lightly before assembling—crispy buns make all the difference. And if you're feeling fancy, add a sprinkle of smoked paprika to the beef rub for extra depth. This isn't just a sandwich—it's a flavor bomb.

The beef keeps beautifully—3-4 days in the fridge wrapped tight, or 3 months frozen. I make a double batch and freeze half for lazy days. The sauce? 5 days in the fridge, but trust me, it disappears faster. Assemble sandwiches right before serving so the buns stay crispy. Leftovers? Wrap tightly in foil and reheat in a skillet for that restaurant-style crunch. Game day just got a whole lot easier.

Step-by-step instructions for Arby's beef and cheddar at home

This is how you get that iconic crispy roast beef with melty cheese layers—just like the original.

Start by trimming any excess fat from the 4 lb beef chuck roast, leaving about ¼ inch of fat cap for flavor and moisture. Pat the roast completely dry with paper towels—this is crucial for that crispy exterior we're after.

In a small bowl, mix together the 2 tbsp kosher salt, 1 tbsp ground black pepper, and 1 tbsp garlic powder. Rub this seasoning mixture all over the roast, pressing it into the meat so it sticks. Let the seasoned roast sit at room temperature for 30 minutes before cooking—this ensures even cooking throughout.

In a shallow dish, combine the ½ cup potato starch with 1 tbsp of the ground black pepper. Roll the seasoned roast in this mixture, pressing gently to coat it evenly. The potato starch will create that signature crispy texture when seared.

Place the coated roast on a wire rack set over a baking sheet. This allows air to circulate around the roast, promoting even browning. Let it rest for 10 minutes before cooking—this helps the starch adhere better to the meat.

Heat the ¼ cup vegetable oil in a large oven-safe skillet over medium-high heat until it shimmers. Carefully add the roast to the skillet and sear for 3-4 minutes on each side until it develops a deep golden-brown crust. The oil should sizzle vigorously—this is your signal that it's ready.

Once the roast is seared, transfer the skillet to a preheated 300°F oven. Roast for 3-4 hours, or until the internal temperature reaches 195°F and the meat is fork-tender. The low and slow cooking ensures the beef stays juicy while developing that signature tenderness.

While the roast cooks, prepare the cheese sauce by combining the 16 oz sharp cheddar cheese, ½ cup mayonnaise, ¼ cup yellow mustard, 2 tbsp horseradish, 1 tbsp white vinegar, and 1 tbsp honey in a saucepan. Cook over low heat, stirring constantly, until the cheese is completely melted and the mixture is smooth. Remove from heat and set aside.

Slice the 2 whole yellow onions into wedges and smash the 8 cloves garlic lightly with the side of a knife. In the same skillet used for searing, sauté the onions and garlic over medium heat for 5-7 minutes until softened and slightly caramelized. This adds a sweet, savory depth to the sandwiches.

Once the roast reaches 195°F, remove it from the oven and let it rest for 15 minutes. Slice the roast against the grain into ½-inch thick slices. Toast the 8 whole sesame seed buns lightly in the oven or on a skillet until golden brown.

Spread a generous layer of the cheese sauce on the bottom half of each bun. Add a slice of the crispy roast beef, a few onion and garlic wedges, and top with the remaining bun half. Serve immediately for that classic Arby's experience—crispy roast beef, gooey cheese, and all the tangy sauce in every bite!

Dietary considerations for arby's beef and cheddar at home

Gluten-Free Adaptations

Skip the sesame seed buns and opt for gluten-free hoagie rolls like the ones from Canyon Bakehouse or Udi's. These hold up well to the cheese sauce without crumbling. For extra crispiness, toast them in a skillet with a little vegetable oil until golden brown.

I've tested this with Mission gluten-free flour tortillas too—they work in a pinch but lack the classic sandwich structure. 🌾

Dairy-Free Options

Replace the sharp cheddar cheese with dairy-free cheddar shreds from brands like Violife or Miyoko's. These melt beautifully and won't compromise the gooey texture. For the sauce, use dairy-free mayo (like Hellmann's Vegan) and ensure your horseradish is also dairy-free.

The flavor stays tangy and rich, just without the lactose. 🧀

Lower-Carb Version

Swap the buns for low-carb lettuce wraps made from large romaine or butter lettuce leaves. This cuts carbs dramatically while keeping the beef and cheese layers intact.

For extra structure, I sometimes use portobello mushroom caps lightly grilled to mimic a bun. The crispy roast beef and melted cheese still shine through! 🥬

Allergen-Friendly Tips

If nut allergies are a concern, double-check your mayo and horseradish labels—some brands process in facilities with nuts. For sesame-free versions, use plain gluten-free buns instead of sesame seed varieties.

I keep Annie's gluten-free buns on hand for these situations—they're soft yet sturdy enough to hold all the fillings. Always verify ingredient labels when adapting recipes! 🚫

Protein Swaps

For a lighter option, replace half the beef with lean ground turkey or chicken breast cooked with the same seasoning blend. The potato starch crust works perfectly on these alternatives too.

Vegetarians can use extra-firm tofu pressed and marinated in the beef rub, then baked until crispy. The texture won't be identical, but it delivers satisfying chew and flavor. 🍗
