Arby’s Roast Beef Recipe: Slow-Roasted Tenderness at Home

Recreating Arby’s signature roast beef at home delivers that same slow-roasted tenderness you crave, without the drive-thru. The secret lies in selecting the right cut—top round works best—and cooking it low and slow until it reaches that perfect, sliceable consistency. Thinly shaved beef is what makes the sandwich, so a sharp knife or meat slicer is essential for authentic results.

This recipe captures the fast-food classic’s essence, from the juicy, pink-centered beef to the toasted sesame bun. Pair it with homemade Horsey Sauce and crispy curly fries for the full experience. The key is patience during roasting and precision when slicing—this ensures every bite matches the original’s signature texture.

The top round roast is non-negotiable for authentic texture—Costco or Whole Foods carry well-marbled options. For the dry rub, Diamond Crystal kosher salt provides superior flavor penetration without over-salting. Beef broth quality impacts moisture retention; Swanson’s low-sodium maintains control over seasoning levels. The sesame buns should be fresh-baked—local bakery versions outperform grocery store options.

Substitutions require careful consideration: chuck roast can replace top round but requires additional trimming. For the Horsey Sauce, Greek yogurt (strained) may substitute mayonnaise at a 1:1 ratio, though texture differs slightly. Apple cider vinegar works in place of white vinegar, adding subtle fruit notes. If avoiding alcohol, coconut aminos replaces Worcestershire at equal volume, though flavor profile alters marginally.

Store the uncooked roast wrapped tightly for up to 5 days refrigerated, or freeze for 6 months. Prepared Horsey Sauce keeps 1 week refrigerated in an airtight container. For optimal slicing, chill the cooked roast 2 hours before using a meat slicer—this maintains the signature thin cuts Arby’s is known for.

Step-by-Step Instructions for Slow-Roasted Top Round

This method transforms economical top round into remarkably tender roast beef with minimal hands-on time.

Step 1: Prepare and Season the Roast

Begin by patting the 3 lb Top Round Roast completely dry with paper towels. This critical step ensures proper browning during searing. Trim any remaining excess fat from the surface, leaving only a thin layer for flavor development.

In a small bowl, combine the 1.5 tbsp Kosher Salt, 1 tbsp Coarsely Ground Black Pepper, 1 tbsp Garlic Powder, and 1 tbsp Onion Powder. Rub this mixture evenly over all surfaces of the roast, pressing gently to adhere. The salt will begin drawing out moisture immediately, so proceed to searing without delay.

Step 2: Sear and Deglaze for Flavor Foundation

Heat a heavy Dutch oven over medium-high heat until a drop of water sizzles immediately upon contact. Add the 1 tbsp Canola Oil and swirl to coat the bottom. Carefully place the seasoned roast in the pot and sear for 3-4 minutes per side until a deep brown crust forms. The crust should develop evenly without burning.

Remove the roast to a plate and reduce heat to medium. Add the 2 tbsp Worcestershire Sauce to the pot, scraping up all browned bits with a wooden spoon. Pour in the 1 cup Beef Broth and bring to a gentle simmer. These flavorful fond will dissolve into the cooking liquid, creating a rich braising base.

Step 3: Slow-Roast to Perfect Tenderness

Return the seared roast to the pot along with any accumulated juices. The liquid should come about one-third up the sides of the meat. Cover tightly and transfer to a 300°F oven. Roast for 2.5 to 3 hours, turning the roast every 45 minutes to ensure even cooking and moisture distribution.

The roast is done when an instant-read thermometer inserted into the thickest part registers 145°F for medium-rare. You’ll notice the meat has shrunk slightly from its raw size and the fibers will appear to separate when probed. Remove from oven and transfer the roast to a cutting board, tenting loosely with foil.

Step 4: Rest and Slice for Optimal Texture

Allow the roast to rest for 20-30 minutes before slicing. This crucial resting period lets the juices redistribute throughout the meat rather than escaping onto the cutting board. The internal temperature will rise about 5-10°F during this time, reaching the ideal serving temperature.

Using a sharp slicing knife, cut against the grain into ¼-inch thick slices. The properly cooked roast should yield easily to the knife with minimal resistance. Arrange the slices on a platter, spooning some of the reduced cooking liquid over the top to maintain moisture.

Step 5: Assemble Sandwiches with Horsey Sauce

While the roast rests, prepare the Horsey Sauce by whisking together the 0.5 cup Mayonnaise, 2 tbsp Prepared Horseradish, 2 tbsp Ketchup, 1 tsp White Vinegar, 0.5 tsp Paprika, and 1 tsp Yellow Mustard until smooth. The sauce should have a pale pink hue with visible horseradish specks.

Lightly toast the 4 whole Sesame Seed Buns until golden. Spread a generous layer of Horsey Sauce on both cut sides of each bun. Arrange the sliced roast beef on the bottom buns, piling the meat high. Cap with the top buns and serve immediately while the meat is still warm and the buns crisp.

Pro Cooking Tips for Great arbys

Temperature Precision Matters

For that signature Arby’s tenderness, your oven must maintain a steady 300°F throughout roasting. I use an oven thermometer to verify accuracy—many home ovens run 25-50°F off their dial setting. A Thermoworks Dot probe thermometer is my go-to for monitoring internal temp without opening the oven door. 🌡️

Searing Secrets

The initial sear creates the flavor foundation. Use a heavy Dutch oven (I prefer Le Creuset) and get it screaming hot before adding oil. The roast should sizzle immediately—if it doesn’t, wait another 2 minutes. Sear each side until you see a deep mahogany crust form, about 3-4 minutes per side.

Resting is Non-Negotiable

After removing from the oven, tent the roast loosely with foil and let it rest for 20-30 minutes. This isn’t optional—skipping it means all those precious juices will spill onto your cutting board instead of staying in the meat. I often rest mine on a warm plate to keep the edges from cooling too quickly.

Slicing Like a Pro

For those paper-thin slices, you’ll need either a meat slicer or a razor-sharp 12-inch slicing knife. I use a Dexter-Russell V-Lo knife. Chill the roast for 30 minutes before slicing—this firms up the meat for cleaner cuts. Slice against the grain at a 15-degree angle for maximum tenderness.

Sauce Timing

Prepare the Horsey Sauce while the roast rests. The flavors need 10 minutes to meld together properly. I make mine in a glass jar so I can shake it vigorously—this incorporates air for a lighter texture. Taste and adjust the horseradish level; Arby’s sauce has a noticeable but not overpowering kick.

Bun Preparation

Toast the sesame buns just before assembly. I use a cast iron skillet over medium heat for 30 seconds per side—this gives that perfect golden crust without drying them out. Brush the cut sides lightly with melted butter for extra richness, just like the restaurant version does. 💛
