This Arbys roast beef copycat recipe delivers the same slow-simmered tenderness and bold flavor that made the chain famous. The secret lies in a low-and-slow roasting method that transforms tough chuck roast into melt-in-your-mouth slices, then a perfectly balanced seasoning blend that mimics the signature taste. Unlike quick searing techniques, this method ensures every bite stays juicy and packed with beefy richness—just like the original.
The process begins with a simple yet effective seasoning of garlic powder, onion powder, black pepper, and a touch of brown sugar to caramelize the edges. The roast cooks for 3 hours at 300°F, allowing the connective tissues to break down naturally. Once sliced, the beef develops a beautiful crust while remaining tender inside, ready to be piled high on toasted buns with optional sauces like Horsey Sauce for that authentic fast-food experience.
What sets this recipe apart is the attention to detail—from the precise cooking time to the way the beef is sliced against the grain for maximum tenderness. The result is a sandwich that captures the essence of Arbys' signature roast beef: rich, savory, and impossible to resist. Whether you're recreating the classic beef 'n' cheddar or experimenting with your own combinations, this method guarantees restaurant-quality results at home.
For the full experience, serve with crispy onion strings, pickles, and a side of fries. The key to success lies in patience and precision—every step is designed to replicate the slow-cooked perfection that made this sandwich a cult favorite. Let’s get started on your copycat masterpiece.
Ingredients for arbys roast beef copycat
The essential ingredients for melt-in-your-mouth Arbys-style roast beef, slow-cooked to perfection with bold seasonings.
| Ingredient | Amount | Notes |
|---|---|---|
| Chuck Roast 🥩 | 3 lb | Well-marbled for tenderness |
| Garlic Powder 🧄 | 2 tsp | Freshly ground preferred |
| Onion Powder 🧅 | 2 tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | 1 tsp | Freshly cracked for intensity |
| Light Brown Sugar 🍯 | 1 tbsp | For caramelization |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Beef Broth 💧 | 1 cup | Low-sodium preferred |
| Yellow Onion 🧅 | 1 whole | Thinly sliced for aroma |
| Garlic Cloves 🧄 | 4 cloves | Minced for depth |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For crust development |
| Russet Potatoes 🥔 | 2 medium | Peeled and sliced for fries |
| All-Purpose Flour 🌾 | 1 cup | For breading buns |
| Cheddar Cheese 🧀 | 4 oz | Shredded for sandwiches |
| Crispy Onion Strings 🧅 | ½ cup | Store-bought or homemade |
| Dill Pickle Chips 🥒 | ¼ cup | For sandwich garnish |
The chuck roast is non-negotiable—its marbling ensures rich flavor and tender texture. Costco or Walmart typically carry it pre-cut for convenience, but if buying whole, trim excess fat. For the seasoning blend, Diamond Crystal kosher salt dissolves better than table salt, and freshly ground black pepper makes a noticeable difference. The brown sugar isn't just for sweetness; it caramelizes beautifully during roasting, mimicking Arbys' signature crust. If you can't find chuck, top round roast works in a pinch, though it'll be slightly leaner.
No beef broth? Low-sodium chicken broth works, but add an extra pinch of salt to compensate. For the potatoes, Yukon Golds hold their shape better than Russets when fried, though Russets give that classic fast-food texture. The garlic and onion powders can be swapped for fresh—just double the amount—but the powders ensure consistent flavor. If you're making a big batch, double the seasoning blend and store it in an airtight container for up to 6 months. The crispy onion strings? Trader Joe's has the best pre-made ones, but homemade fried onions are worth the effort.
The roast keeps beautifully for 4-5 days in the fridge, sliced thinly against the grain for maximum tenderness. For meal prep, portion the beef into containers with a light sprinkle of beef broth to keep it moist. The seasoning blend stays potent for 3 months in a sealed jar. Potatoes for fries should be cooked fresh or reheated in the oven at 400°F for 5-10 minutes to restore crispiness. Store the pickles and onion strings separately—they'll stay crunchy for 1 week in the fridge.

Step-by-step instructions for slow-simmered roast beef
Here's the professional method to replicate Arby's signature roast beef texture and flavor at home.
Season and Sear the Chuck Roast
Pat the 3 lb chuck roast dry with paper towels—this ensures maximum browning. In a small bowl, combine the 2 tsp garlic powder, 2 tsp onion powder, 1 tsp black pepper, 1 tbsp light brown sugar, and 1.5 tsp salt. Rub this mixture evenly over all sides of the roast, pressing it into the meat so it adheres well.
Heat 1 tbsp extra-virgin olive oil in a large Dutch oven over medium-high heat. Once shimmering, add the seasoned roast and sear on all sides for 4-5 minutes per side until developing a deep golden-brown crust. This initial searing locks in flavors and creates that signature caramelized exterior.
Simmer with Aromatics and Broth
Remove the roast from the Dutch oven and set aside. In the same pot, add the 1 whole yellow onion (thinly sliced) and 4 cloves garlic (minced). Sauté for 3-4 minutes until softened and fragrant, stirring occasionally. This builds the flavor base for the sauce.
Return the roast to the pot, add 1 cup beef broth, then cover tightly. Reduce heat to low and simmer for 2.5-3 hours, turning the roast occasionally. The meat should become fork-tender and easily pull apart when tested. The liquid should reduce to a rich, glossy sauce that coats the back of a spoon.
Shred and Prepare the Potato Fries
Once the roast reaches 203°F internal temperature (use a meat thermometer), remove it from the pot and shred using two forks. Discard any large fat pieces and return the shredded meat to the pot with the cooking juices. Keep warm on low heat while you prepare the sides.
Cut the 2 medium russet potatoes into ¼-inch thick sticks. Toss them in 1 cup all-purpose flour until evenly coated. Heat 1 tbsp extra-virgin olive oil in a skillet over medium-high heat until shimmering. Fry the potatoes in batches for 3-4 minutes until golden and crispy. Drain on paper towels and season lightly with salt.
Assemble the Copycat Sandwiches
Toast 4 hamburger buns until golden and crisp. Layer each with 2 oz shredded cheddar cheese, ¼ cup roast beef, 0.5 tbsp crispy onion strings, and 1 tbsp dill pickle chips. Press down gently to melt the cheese slightly and create that signature sandwich structure.
Serve immediately with the potato fries on the side. The roast beef should be tender yet slightly resistant, with a rich, savory sauce clinging to each strand. The combination of crispy fries, melted cheese, and that perfect pull-apart texture delivers the authentic Arby's experience.
Pro Tips For Making Arbys Roast Beef Copycat
- SEAR THE ROAST FIRST: That crust is what makes this dish taste like Arby’s—not the sauce. Hit the chuck roast with a hot pan for 3-4 minutes per side before adding anything else. I used to skip this, and the meat always ended up bland and dry no matter how long I braised it.
- USE REAL GARLIC (NOT POWDER): The recipe calls for garlic powder, but I’ve found that mincing 2-3 fresh garlic cloves and sautéing them in the pan with the onions makes a world of difference. It’s not copycat anymore—it’s better. Yes, it takes 30 seconds extra, but trust me.
- DON’T OVERLOAD THE SUGAR: The brown sugar caramelizes into that sweet, sticky glaze, but too much turns the meat cloying. Stick to 2 tablespoons max—any more, and you’ll end up with a dessert, not roast beef. I learned this after burning a batch where I doubled it.
- REST THE MEAT UNDER FOIL: After pulling it from the oven, tent the roast with foil and let it sit for 10 minutes. This keeps it juicy and makes slicing cleaner. I used to cut into it right away, and the first few slices were always dry—now I never do that.

Frequently asked questions
Can I use a different cut of beef instead of chuck roast?
Chuck roast is ideal because its marbling creates rich flavor and tender texture when slow-cooked. You could try top round roast as a leaner alternative, but it won't be as juicy. For best results, stick with chuck—it's the secret to that signature Arby's melt-in-your-mouth quality. If you must substitute, add 1 tbsp beef tallow to the pan during searing to compensate for lost fat.
How do I make the beef extra tender?
The 3-hour low-and-slow cook time at 300°F is key, but for maximum tenderness, slice the roast against the grain before shredding. This shortens the muscle fibers and creates that perfect pull-apart texture. Also, don't overcook—remove the beef when it reaches 203°F internal temp, not 212°F. The residual heat will finish cooking it while keeping it moist.
What's the best way to reheat leftovers?
Reheat shredded beef in a skillet over medium-low heat with 1 tbsp beef broth for 3-4 minutes until warmed through. Avoid microwaving—it makes the meat rubbery. For sandwiches, toast the buns fresh and assemble with reheated beef and cheese. The fries should be reheated in a 400°F oven for 5-10 minutes on a wire rack to restore crispiness.
Can I make this in a slow cooker?
Brown the roast first in a skillet, then transfer to the slow cooker with onions, garlic, and broth. Cook on low for 6-7 hours or high for 3-4 hours. The slow cooker method works especially well for meal prep—just shred and store the beef separately from the cooking juices to keep it fresh longer.
Why does my beef turn out dry?
Dry beef usually means overcooking or starting with lean meat. Always use chuck roast and remove it at 203°F. If you're concerned about drying out, cover the pot tightly during cooking and add ½ cup extra broth if the liquid reduces too quickly. Also, let the beef rest for 10 minutes after cooking before shredding to retain juices.
