This Arby's roast beef sandwich copycat recipe delivers the iconic combination of tender, slow-roasted beef, crispy tortilla shells, and that signature au jus-soaked crunch. 🔥 The secret lies in marinating the beef overnight for maximum flavor penetration and cooking it low-and-slow until fork-tender.
I've recreated this classic sandwich exactly as you'd find it at the restaurant, right down to the tangy au jus and crisp pickles.
The recipe begins with a simple yet effective marinade that transforms tough cuts of beef into melt-in-your-mouth perfection. After slow-roasting, the beef is thinly sliced and piled high on crispy tortilla shells that have been soaked in the rich, savory au jus.
This technique ensures every bite delivers that signature combination of textures and flavors that made Arby's famous.
What sets this copycat apart is the attention to detail in recreating the tortilla crunch and au jus balance.
The tortillas are toasted until golden and crispy, then generously soaked in the homemade au jus mixture, which is made with beef broth, vinegar, and a touch of brown sugar for that perfect tangy-sweet balance.
Each sandwich comes together with layers of flavor and texture that stay true to the original.
Perfect for satisfying that fast-food craving without the drive-thru wait, this recipe serves four and comes together in about 2 hours of active time plus overnight marinating.
The result is a sandwich that's so good, you'll wonder why you ever bought it anywhere else. Let's get started on making this restaurant-quality meal at home.
Ingredients for arby's roast beef sandwich copycat
Here's what you'll need to recreate that iconic Arby's taste at home.
| Ingredient | Amount | Notes |
|---|---|---|
| Beef Chuck Roast 🥩 | 2 lb | Tough cut, marbled for tenderness |
| Yellow Onion 🧅 | 1 whole | Chopped into small dice |
| Garlic Cloves 🧄 | 6 cloves | Minced for marinade |
| Worcestershire Sauce 🍶 | 2 tbsp | Vegan version if needed |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred |
| Black Peppercorns 🌶️ | 1 tsp | Freshly ground preferred |
| Beef Broth 🍲 | 2 cups | Low-sodium preferred |
| White Vinegar 🍶 | ½ cup | For tangy au jus |
| Brown Sugar 🍯 | 1 tbsp | Light or dark variety |
| Flour Tortillas 🌯 | 8 whole | Medium size, 10-inch |
| Dill Pickle Slices 🥒 | ½ cup | Thinly sliced for crunch |
| Russet Potatoes 🥔 | 2 medium | For crispy potato chips |
| Vegetable Oil 🫒 | ½ cup | For frying tortillas |
| Mayonnaise 🥫 | ¼ cup | For optional spread |
| Sweet Pickle Relish 🥒 | ¼ cup | For serving |
The beef is the star—chuck roast is key for that melt-in-your-mouth texture. Look for well-marbled cuts at Costco or Kroger—they usually have it pre-cut for convenience. If you're buying whole, ask the butcher to trim excess fat. The Worcestershire sauce adds depth, so don't skip it (vegan versions work too). For the au jus, low-sodium beef broth keeps the flavor balanced without extra salt. I grab mine from the Trader Joe's bulk section—cheaper and fresher than canned options.
No chuck roast? Top round or sirloin tip works in a pinch, though it'll be slightly leaner. Short on pickles? Dill pickle juice plus thinly sliced cucumbers gives you that tangy crunch. The tortillas should be medium-sized (10-inch) for that classic Arby's shape—Mission brand is my go-to. For extra crunch, fry them in vegetable oil at 375°F until golden. The potato chips? Store-bought works fine, but homemade (thinly sliced, fried until crispy) tastes even better.
The au jus keeps for 5 days in the fridge—perfect for dipping extra tortillas. Store the beef in an airtight container with the marinade for up to 3 days. Tortillas lose crispiness fast, so toast them fresh before assembling. Make a double batch of au jus—it's great for dipping fries or even as a marinade for other meats. The pickles stay fresh for weeks if you keep them submerged in their juice.
Why You'll Love This Recipe
- Slow-Cooker Simplicity: I swear by this for days I’d rather not stand over the stove. Chuck roast, onions, and a splash of Worcestershire? Toss it in the slow cooker, hit low, and forget it until the meat shreds itself. That’s 8 hours of zero effort for flavor that hits the spot.
- Umami Bomb: Here’s what sold me—the way the Worcestershire and garlic caramelize into the beef. It’s not just salty; it’s that deep, savory punch you crave when you’re halfway through a movie and realize you’re starving. (Yes, even on a Tuesday night.)
- Leftover Goldmine: This recipe actually improves the second day. Shredded beef keeps for ages, so I make a double batch and stash it for quick lunches or tacos. My kids beg for it—honestly, they’d eat it cold if I let them.
- Budget Powerhouse: A chuck roast is cheaper than takeout, and the ingredients cost pennies. I’ve made this feed a crowd for under $15, and no one ever guesses it’s not from the drive-thru. That’s a win for my wallet and my picky eaters.
Step-by-step instructions for Arby's-style roast beef sandwiches
Here's how to nail that iconic Arby's crunch and flavor at home.
🔥 Step 1: Slow-Cook the Tender Beef
Pat the 2 lb Beef Chuck Roast dry with paper towels and place it in a slow cooker. Add the 1 whole Yellow Onion (chopped), 6 cloves Garlic Cloves (minced), 2 tbsp Worcestershire Sauce, 1.5 tbsp Kosher Salt, and 1 tsp Black Peppercorns. Pour in 2 cups Beef Broth and 0.5 cup White Vinegar, then sprinkle with 1 tbsp Brown Sugar. The sugar helps caramelize the meat during cooking.
Cover and cook on LOW for 8 hours or HIGH for 5-6 hours until the beef is fork-tender and shreds easily. I like to check it at the 6-hour mark on high heat—it should pull apart with minimal resistance. If it's not quite there, give it another hour. Real talk: This is the moment that makes or breaks your sandwich, so don't rush it.
🍳 Step 2: Make the Au Jus and Crispy Potato Chips
Remove the beef from the slow cooker and shred it using two forks, discarding any large fat chunks. Return the shredded beef to the pot and stir in 0.5 cup Dill Pickle Slices—they'll add that signature tangy crunch. Keep the slow cooker on WARM while you make the potato chips.
Slice the 2 medium Russet Potatoes into ¼-inch thick rounds. Toss them with 0.5 cup Vegetable Oil and spread them in a single layer on a baking sheet. Bake at 425°F for 20-25 minutes, flipping halfway, until golden and crispy. You want them to be crunchy enough to stand up to the sandwich—like little potato chips. Keep them warm while you finish the sandwiches.
🥘 Step 3: Fry the Au Jus-Soaked Tortillas
Place the 8 whole Flour Tortillas in a large skillet over medium heat. Let them warm for 1 minute per side until pliable but not browned. Immediately transfer them to a plate and pour the au jus (the liquid from the slow cooker) over them, letting them soak for 2 minutes. This step is crucial—the tortillas need to absorb that rich, tangy flavor.
Working in batches, fry the soaked tortillas in 0.5 cup Vegetable Oil over medium-high heat for 30-45 seconds per side until deep golden brown and crispy. I press down gently with a spatula during the first 10 seconds—this prevents them from curling and ensures even contact with the oil. Drain on paper towels and keep warm in a 200°F oven while you assemble the sandwiches.
🍽️ Step 4: Assemble Like a Pro
Spread 0.25 cup Mayonnaise on each crispy tortilla, then layer with shredded beef, a handful of 0.5 cup Dill Pickle Slices, and a sprinkle of extra au jus. For that classic Arby's touch, add a spoonful of 0.25 cup Sweet Pickle Relish on top. The relish adds a sweet contrast that balances the savory beef and tangy pickles.
Cut each sandwich diagonally into quarters and serve immediately with a side of the au jus for dipping. The key here is the contrast—crispy tortilla, tender beef, crunchy pickles, and that sticky-sweet relish. It's all about texture and layers of flavor, just like the real deal.
Pro Tips For Making Arby'S Roast Beef Sandwich Copycat
- Sear First, Then Braise: The chuck roast needs a hot pan before liquids—crust seals in flavor. I used to skip this, and the beef stayed bland. Hit 400°F in a heavy pot, sear 2-3 minutes per side until brown, then add onions, garlic, and Worcestershire.
- Slice Onions Thin: Thin, even slices (⅛-inch) cook faster and caramelize better than thick chunks. I learned this after staring at a pot of half-raw onions for 20 minutes. Use a mandoline if you’re impatient.
- Don’t Overcrowd the Pan: Too many onions? They steam instead of brown. Cook them in batches if needed—golden color means flavor. I’ve ruined batches by tossing everything in at once.
- Rest Before Slicing: Let the beef sit 10 minutes after cooking. Skipping this means dry, stringy slices. Tent loosely with foil, and it’ll stay juicy while you prep the rest. Your sandwiches will thank you.
Common mistakes when making this dish
Overcooking the Beef
The beef should be fork-tender, not falling apart into a mushy pile.
I’ve seen people walk away from the slow cooker for too long, and suddenly, you’ve got beef that’s more like ground meat than shreds. Check it at the 6-hour mark on high heat—it should pull apart easily but still hold its shape.
If it’s falling apart prematurely, you’ve gone too far. Trust me, the beef will keep cooking even after you remove it from the heat, so it’s better to pull it out a little early than to overcook it.
Skipping the Au Jus Soak
This is where most copycat recipes fail—they skip soaking the tortillas in the au jus. Without this step, your sandwich will taste dry and lack that signature sticky, tangy flavor. Let the tortillas soak for the full 2 minutes before frying.
If you rush this, the tortillas won’t absorb enough flavor, and your sandwich will miss a critical component of the Arby’s experience. Think of it like marinating the tortillas—they need that time to transform.
Frying Tortillas Too Long
Frying the tortillas for more than 45 seconds per side turns them from crispy to burnt. I’ve made this mistake more times than I’d like to admit—next thing you know, you’ve got a pile of blackened, bitter tortillas instead of golden, crunchy shells.
Keep a close eye on them, especially if your stove runs hot. If they start to darken too quickly, reduce the heat slightly or fry in smaller batches. The goal is a deep golden brown, not charred.
Using the Wrong Tortillas
Not all flour tortillas are created equal. If you grab just any brand from the store, you might end up with tortillas that are too thin or too thick, or worse—too soft. Stick with medium-sized (10-inch) flour tortillas, like Mission brand.
They hold up well to frying and soaking, giving you that perfect balance of crispiness and structure. Thin or pre-shredded tortillas won’t cut it—they’ll turn into sad, soggy messes.
Ignoring the Potato Chips
Yes, the potato chips are non-negotiable. They add a layer of crunch and texture that balances the softness of the beef and tortillas. If you skip them or use store-bought chips that are too soft, your sandwich will feel incomplete.
Bake them at 425°F for 20-25 minutes, flipping halfway, until they’re golden and crispy. Pro tip: Keep them warm in a 200°F oven while you assemble the sandwiches so they stay crunchy until serving.
Overloading the Sandwich
Piling too much beef, pickles, and relish on one tortilla can turn your masterpiece into a messy, soggy disaster. The tortillas can only handle so much before they lose their crispiness.
I like to use about ½ cup of shredded beef per sandwich and keep the pickles and relish in moderation. Think of it like layering a cake—balance is key. If your sandwich starts to look like it’s about to collapse under its own weight, scale back slightly.

Frequently asked questions
Can I make this recipe without a slow cooker?
Use a Dutch oven instead. Sear the beef first in a skillet, then transfer it to the Dutch oven with all marinade ingredients. Cover and bake at 300°F for 4-5 hours until tender. The key is keeping the heat low and the beef submerged in liquid to prevent drying out.
How do I keep the tortillas crispy when assembling?
Fry the tortillas fresh and keep them warm in a 200°F oven while assembling. Only spread mayo and add toppings right before serving—this prevents sogginess. If you need to hold them longer, place them on a wire rack over a baking sheet to maintain crispness.
What if I don't have beef chuck roast?
Use top round or sirloin tip instead—they're leaner but still tender when cooked low-and-slow. For extra moisture, add 1 tbsp tomato paste to the marinade. Avoid using tender cuts like ribeye, as they'll turn tough when slow-cooked.
Can I make the au jus ahead of time?
Yes! The au jus keeps well for 5 days in the fridge. Strain it to remove any solids before storing, then reheat gently before using. You can even freeze it for up to 3 months. Just thaw it overnight in the fridge before using for soaking tortillas.
How do I make this vegetarian?
Replace the beef with shredded jackfruit or extra-firm tofu marinated in the same sauce. Use mushroom broth instead of beef broth and add 1 tbsp soy sauce for umami depth. The tortilla technique and au jus remain the same for that signature texture.
