Ingredients for arbys roast beef sandwich copycat
Six ingredients make the beef, eight build the sandwich—nothing fancy, just pure nostalgia.
| Ingredient | Amount | Notes |
|---|---|---|
| Chuck Roast 🥩 | 3 lb | Center-cut for tenderness |

The chuck roast is non-negotiable—Costco sells it pre-cut for convenience, but grab a whole roast from the butcher section if you want to trim excess fat yourself. Look for good marbling; that's where the flavor hides. The A1 Worcestershire sauce is worth hunting down—it's the secret weapon behind that signature tang. If you can't find it, Lee & Perrins works in a pinch, but you'll miss that deep umami punch. For the garlic, I always grab a head and peel it all at once—8 cloves is perfect for this batch, but eyeball it if you're making more.
No beef broth? Water plus 1 tbsp soy sauce gets you close, but the depth suffers. The brown sugar might seem odd, but it balances the acidity of the Worcestershire—muscovado or demerara adds extra complexity if you're feeling fancy. For the buns, Arby's uses a proprietary potato roll, but any soft, slightly sweet bun works. The horseradish mayo? Hellmann's with a squeeze of prepared horseradish is my go-to. Lettuce and tomatoes should be crisp and dry—skip the pre-washed bags, they wilt fast. If you're short on time, baby spinach can sub for lettuce, but the texture won't be the same.
The beef keeps 3-4 days in the fridge, but the gravy? Make extra—it reheats beautifully and tastes even better the next day. Store it separately in an airtight container with a splash of broth to keep it from drying out. The buns toast best when warmed 2 minutes at 350°F before assembling. For meal prep, slice the beef thin, portion the gravy, and keep the toppings separate until serving. This sandwich is all about assembly freshness—no sad soggy lettuce here. Freeze the beef and gravy together for up to 3 months if you're planning ahead.

Step-by-step instructions for Arbys roast beef sandwich copycat recipe
Here's how to nail that iconic saucy, tender roast beef with homemade gravy.
🔥 Step 1: Sear and Braise the Chuck Roast
Pat the 3 lb chuck roast completely dry with paper towels—this ensures a perfect sear. Heat a Dutch oven over medium-high heat and add 1 tablespoon olive oil (not listed but essential). Sear the roast on all sides until deeply browned, about 4-5 minutes per side. Real talk: don't rush this step. You want that dark crust that carries all the flavor.
Remove the roast and set it aside. Add the 1 whole yellow onion, chopped, and 8 cloves garlic, minced, to the Dutch oven. Cook for 3-4 minutes until softened. Sprinkle in 1.5 tsp salt and 1 tsp black peppercorns (cracked between your fingers for freshness). Pour in 2 cups beef broth and scrape up all those browned bits from the bottom—this is where the flavor lives.
🥘 Step 2: Slow Cook Until Fork-Tender
Return the roast to the Dutch oven, fat-side up. Cover and transfer to a 325°F oven. Here's the thing—this low-and-slow cook is crucial. Braise for 3-3.5 hours until the meat is fork-tender. You'll know it's ready when a knife slides in easily and the internal temperature reaches 195-200°F. The meat should pull apart with minimal resistance, not fight you.
About 1 hour before the roast is done, add 2 tbsp Worcestershire sauce and 1 tbsp brown sugar to the Dutch oven. Stir gently to combine. This sweet-savory punch mimics that signature Arby's flavor. The sugar caramelizes slightly, adding depth to the gravy we're about to make.
🍳 Step 3: Create the Signature Saucy Gravy
Once the roast is done, remove it from the Dutch oven and let it rest on a cutting board for 15 minutes (don't skip this—juices need time to redistribute). Strain the cooking liquid through a fine-mesh sieve into a clean pot, pressing on the solids to extract maximum flavor. This gives you about 2 cups of rich, meaty liquid.
Return the liquid to the Dutch oven over medium heat. Whisk in 2 tbsp all-purpose flour to thicken the gravy. Cook for 3-4 minutes until it reaches a smooth, velvety consistency. Here's where we get saucy: stir in 0.5 cup horseradish mayo and 1 tsp toasted sesame oil. The mayo adds that signature creaminess while the sesame oil brings a subtle umami depth. Simmer for another 2 minutes—just until everything melds together.
🔪 Step 4: Assemble the Classic Sandwiches
While the gravy simmers, slice the rested roast against the grain into ¼-inch thick slices. This is non-negotiable for tenderness. Toast the 6 whole Arbys-style buns according to package instructions—crispy buns are essential. Here's the assembly order: start with the bottom bun, then add 2 slices roast beef, a generous spoonful of that saucy gravy (about 2 tbsp per sandwich), iceberg lettuce (4 leaves per sandwich), ¼-inch tomato slices (2 per sandwich), and thin white onion slices (about 6 per sandwich).
Top with the second bun and press gently. The gravy should ooze slightly when you cut into it—that's how you know you've nailed it. Serve immediately while the buns are still warm and the gravy is saucy. This isn't a sandwich you want to make ahead—every bite should be fresh from the assembly line.
Pro Tips For Making Arbys Roast Beef Sandwich Copycat
- SEAR THE ROAST FIRST: High heat. Seriously, crank it up to medium-high and let that chuck roast develop a deep brown crust before adding any liquid—this isn’t just for flavor, it’s the foundation of that rich, caramelized taste. I used to skip this and ended up with beef that tasted more like stew than slow-cooked perfection.
- SWEAT THE ONIONS LOW: Don’t rush this step—cook the onions and garlic on low heat for at least 10 minutes until they’re soft and translucent, not crispy. I learned this the hard way when I burned them twice and had to start over; patience here means the sauce won’t turn bitter later.
- USE FULL-STRENGTH BROTH: Skip the watered-down stuff—go for a rich, high-quality beef broth (like the kind you’d use for gravy) and reduce it by half before adding it to the pot. The deeper flavor makes all the difference, and you’ll actually taste the Worcestershire sauce instead of just the salt.
- REST THE MEAT UNDER FOIL: After pulling the roast from the pot, tent it with foil and let it rest for 10-15 minutes before slicing—this keeps it juicy and makes it easier to shred. I know, I know, but trust the process: cutting into it too soon turns that tender meat into dry, sad shreds.
Essential equipment for great arbys roast beef sandwich copycat
Dutch Oven
The Dutch oven is your secret weapon for this recipe—it sears, braises, and even holds heat like a pro. I recommend a 5.5-quart Lodge cast iron Dutch oven for even heat distribution and durability. The thick walls maintain 325°F perfectly during the slow cook, while the tight lid traps steam for fork-tender beef. If you don’t own one, a heavy-bottomed pot with a tight lid works in a pinch, but expect slightly less even cooking. 🔥
Meat Thermometer
Skipping the meat thermometer is a rookie mistake—this recipe demands precision. A Thermoworks Smoke or Taylor Precision model gives instant readings, ensuring your beef hits 195-200°F without overcooking. The probe should slide into the thickest part of the roast like butter. Pro tip: Use the hold function to monitor temps without opening the oven door and losing heat. 🌡️
Sharp Knife + Cutting Board
Thin, even slices are non-negotiable for that Arby’s texture. A Wüsthof Ikon or Victorinox Fibrox chef’s knife handles the job beautifully, but any 8-inch sharp knife works. Pair it with a non-slip cutting board (I love the OXO Good Grips) to prevent accidents. Slice against the grain at a ¼-inch thickness—this is where the magic happens. A mandoline speeds up the process, but be cautious with thick roasts. ✂️
Fine-Mesh Sieve
Straining the cooking liquid through a fine-mesh sieve (like the OXO Good Grips) removes impurities, giving you a silky-smooth gravy. Press the solids gently with a spoon to extract every last drop of flavor—this is where the depth comes from. If you’re in a bind, a cheesecloth-lined colander works, but it’s messier. The sieve also helps remove any stray onion bits that could make your gravy grainy. 🥄
Instant-Read Thermometer
While your meat thermometer monitors the roast, an instant-read thermometer (like the Thermapen) comes in handy for checking gravy temperature and bun toastiness. The gravy should reach 160°F before adding mayo to prevent curdling. For the buns, aim for 165°F at the center—this ensures they’re perfectly toasted without burning. Keep one handy for all your temps! ⏱️
Mixing Bowls + Whisk
Two stainless steel mixing bowls (one for resting the beef, one for prepping toppings) keep your workspace organized. A balloon whisk (like the OXO Good Grips) is perfect for blending the gravy and flour into a smooth paste. Avoid plastic—it scratches easily and can harbor bacteria. For extra flair, use a small whisk to emulsify the mayo into the gravy at the end. 🥣

Frequently asked questions
What cut of beef works best for this copycat recipe?
Always use a 3 lb chuck roast—it's the secret to that signature tender, flavorful beef. Look for a center-cut piece with good marbling for maximum juiciness. Avoid leaner cuts like sirloin, as they won't become as tender during the slow cooking process.
How do I get the beef as tender as Arby's?
The key is slow cooking to 195-200°F internal temperature—this breaks down the connective tissue. Slice against the grain at ¼-inch thickness for maximum tenderness. The 3.5-hour braise at 325°F is non-negotiable for that melt-in-your-mouth texture.
Can I make this ahead of time?
You can prep the beef and gravy 1-2 days ahead and store them separately in airtight containers. Reheat the beef and gravy together over low heat until warmed through. However, assemble the sandwiches fresh—lettuce wilts and buns lose crispness when made ahead.
What if I don't have A1 Worcestershire sauce?
Use Lee & Perrins as a substitute, though you'll lose some of that signature umami depth. For extra tang, add ½ teaspoon of prepared horseradish to the gravy. The brown sugar helps balance any flavor differences between brands.
How do I keep the buns from getting soggy?
Toast the buns right before assembling and keep them warm in a 200°F oven while you prep the toppings. Assemble sandwiches with the beef and gravy first, then add lettuce and tomato last. Press gently to help the gravy distribute without making the buns soggy.
