Arbys Roast Beef Copycat Recipe: Au Jus-Poached Tenderness with Crispy Tortilla Bites

This Arbys roast beef copycat recipe delivers the same melt-in-your-mouth tenderness and rich au jus that made the chain famous. The secret lies in slow-cooking beef until it practically falls apart, then serving it on toasted buns with crispy tortilla bites that mimic the original's signature crunch.

I've perfected this method after countless test batches, ensuring every bite captures that iconic Arbys flavor profile.

The process starts with marinating beef chuck roast in a blend of Worcestershire, garlic powder, and black pepper before slow-cooking it until fork-tender. This foolproof method transforms tough cuts into succulent slices that soak up the flavorful au jus.

The tortilla bites get a crispy texture through careful baking, adding that satisfying crunch that Arbys fans crave.

What you'll end up with is a sandwich that rivals the original—juicy, flavorful beef with tender tortilla bites and a rich au jus that ties everything together. The beef stays moist while developing deep, savory flavors, and the tortilla bites achieve that perfect crispy texture without becoming greasy.

Serve with classic sides like crispy fries or creamy coleslaw for the full Arbys experience. This recipe makes four generous sandwiches, perfect for feeding a crowd or satisfying cravings for weeks. Let's get started on recreating this iconic fast-food favorite at home.

Fourteen ingredients transform into iconic Arbys-style roast beef with crispy tortilla bites and rich au jus.

The beef chuck roast is non-negotiable for this recipe—bone-in delivers superior flavor and moisture. Purchase from a quality butcher or Costco's bulk section for the best marbling. Avoid pre-cut roasts from the grocery store's deli counter, as they often contain less fat. If you can't find chuck, bottom round is an acceptable substitute, though the texture will differ slightly. For the Worcestershire sauce, Lea & Perrins is the gold standard—avoid reduced-sodium versions, as they lack depth. The garlic powder should be freshly ground; pre-ground loses potency quickly, so check the expiration date if buying in bulk.

No Worcestershire? A blend of soy sauce, vinegar, and a pinch of cloves mimics the umami profile, though it won't be identical. The tomato paste can be substituted with 1/4 cup crushed tomatoes, but you'll lose the concentrated sweetness. For the tortillas, Mission brand or La Tortilla Factory deliver consistent results—avoid store-brand varieties, which often lack the necessary crispness. If you're short on time, pre-cut tortilla triangles from the freezer section work in a pinch, though they won't achieve the same texture. The sesame seed buns should be toasted lightly before assembling to mimic Arbys' signature crunch; Potato buns from the bakery section are a good alternative if sesame is unavailable.

The au jus thickens beautifully when reduced, but if you prefer a smoother consistency, blend it briefly before serving. Store leftovers in airtight containers with the au jus poured over the beef to maintain moisture—3-4 days in the fridge or 3 months frozen. For the tortilla bites, bake only until golden; overcooking leads to a rubbery texture. Assemble sandwiches fresh to prevent sogginess, or toast the buns again before serving if prepping ahead. The parsley garnish is optional but adds a bright contrast to the rich beef; cilantro works if you prefer a different herb profile.

Step-by-step instructions for Arbys roast beef copycat recipe

Master the perfect balance of au jus-poached beef and crispy tortilla bites with these precise techniques.

Pat the 2 lb Beef Chuck Roast dry with paper towels, removing any surface moisture. This step is critical for achieving that signature crispy bark. In a small bowl, combine 1 tbsp Garlic Powder, 1 tbsp Black Peppercorns (coarsely ground), 1 tsp Salt, and 2 tbsp Worcestershire Sauce. Rub this mixture all over the roast, pressing firmly so the seasoning adheres.

Heat a heavy Dutch oven over medium-high heat and add 2 tbsp Vegetable Oil. Once shimmering, add the roast and sear on all sides for 3-4 minutes per side until deeply browned. This initial sear locks in flavors and creates the foundation for that iconic Arby's crust. Remove the roast and set aside on a plate.

In the same Dutch oven, add 1 whole Yellow Onions (sliced), 4 cloves Garlic Cloves (minced), and 1 tbsp Tomato Paste. Cook for 2-3 minutes until the onions soften and the garlic becomes fragrant. Pour in 2 cups Beef Broth and scrape up any browned bits from the bottom of the pot with a wooden spoon.

Return the roast to the Dutch oven, fat-side up, and bring the liquid to a gentle simmer. Cover with a tight-fitting lid and reduce heat to low. Poach the beef for 2-2.5 hours until fork-tender. The internal temperature should reach 195-200°F—this is where the collagen breaks down, creating that melt-in-your-mouth texture. If the liquid reduces too much, add ¼ cup water to maintain moisture.

Once the beef reaches the proper temperature, remove it from the Dutch oven and tent loosely with aluminum foil. Strain the cooking liquid through a fine-mesh sieve into a clean saucepan. Return the strained liquid to medium heat and whisk in 1 tbsp Cornstarch mixed with 2 tbsp cold water to create a slurry. Simmer for 3-4 minutes until the au jus thickens to a glossy, syrupy consistency.

Add 1 tsp Granulated Sugar and 1 tbsp Worcestershire Sauce to balance the flavors. Taste and adjust seasoning with additional salt if needed. The au jus should coat the back of a spoon and have a rich, slightly tangy flavor. Keep warm over low heat while you prepare the tortilla bites.

Cut each of the 12 pieces Corn Tortillas into 6 wedges, creating a total of 72 pieces. Heat 2 tbsp Vegetable Oil in a large skillet over medium-high heat until shimmering. Working in batches, add the tortilla wedges and fry for 1-2 minutes per side until golden brown and crispy. Drain on paper towels and keep warm in a 200°F oven while you assemble the sandwiches.

Here's the thing—don't overcrowd the pan or the tortillas will steam instead of crisp. You want that satisfying crunch that's a hallmark of the original. If they lose crispiness, simply reheat in the oven for 2-3 minutes before serving.

Slice the beef against the grain into ¼-inch thick slices. Toast the 4 whole Sesame Seed Buns lightly if desired. Assemble each sandwich with beef slices, crispy tortilla bites layered on top, and generously drizzle with the warm au jus. Garnish with 0.25 cup Fresh Parsley chopped for freshness.

Serve immediately with extra au jus on the side for dipping. The contrast between the tender, poached beef, crispy tortilla bites, and rich au jus is what makes this copycat recipe so successful. Each bite should deliver that perfect balance of textures and flavors that Arby's fans know and love.

Common mistakes when making this dish

Overcooking the Beef

One of the biggest mistakes is letting the beef cook past 200°F—this turns it dry and stringy instead of tender. I’ve seen people walk away from the stove only to return to beef that’s overcooked and tough.

Use a meat thermometer and remove it when it hits 195-200°F. The beef will continue cooking slightly from residual heat as it rests. 🌡️

Skipping the Sear

Many copycat recipes skip the initial sear, but this step is non-negotiable for that iconic Arby’s crust. A proper sear locks in flavors and creates a flavorful bark.

I’ve tried it both ways—seared beef tastes completely different from unseared. Use a heavy Dutch oven and let it brown deeply on all sides before poaching.

Underseasoning the Au Jus

The au jus is where the magic happens, but it’s easy to underseason it. Taste it before serving—if it’s bland, add more Worcestershire, a pinch of salt, or even a dash of soy sauce.

I’ve ruined batches by assuming the broth’s saltiness would carry it. The au jus should be rich, slightly tangy, and coat the back of a spoon. 💡

Overcrowding Tortilla Bites

Frying tortilla bites in a crowded pan leads to soggy, greasy results instead of crispy ones. Work in small batches and avoid overloading the skillet. I once fried all 72 wedges at once, and they came out greasy and limp.

A medium-high heat skillet with just enough room for a single layer ensures that perfect crunch. 🔥
