Recreating Arby’s signature roast beef at home requires precision—slow-roasting at 250°F for hours to achieve that fall-apart tenderness. The secret lies in the seasoning blend and careful temperature control, ensuring the meat stays juicy while developing the iconic flavor profile.
What sets this apart is the au jus, simmered with the beef drippings for depth. Paired with toasted sesame buns and the right sauce balance, you’ll replicate the restaurant experience. This method delivers tender, sliceable roast beef that rivals the original—no specialty equipment needed.
Ingredients for Arbys
Precision ingredients for restaurant-quality roast beef: slow-roasted tenderness with au jus depth and signature seasoning balance.
| Ingredient | Amount | Notes |
|---|---|---|
| Beef Round Roast (top round or bottom round) 🥩 | 3 ½ lb | Trimmed of excess fat, room temperature |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred for precision |
| Coarsely Ground Black Pepper 🌶️ | 1 tbsp | Freshly ground for optimal potency |
| Garlic Powder 🧄 | 1 tbsp | High-quality, without anti-caking agents |
| Onion Powder 🧅 | 1 tbsp | Freshly opened for maximum flavor |
| Smoked Paprika 🌶️ | 1 tsp | Spanish variety for authentic depth |
| Dried Thyme 🌿 | 1 tsp | Rubbed between palms to release oils |
| Beef Bouillon Powder 🍲 | 2 tbsp | Low-sodium preferred for au jus control |
| Unsalted Butter 🧈 | 2 tbsp | European-style for richer au jus |
| All-Purpose Flour 🌾 | 1 tbsp | For thickening au jus slurry |
| Sesame Seed Buns 🍞 | 6 whole | Toasted until golden for serving |
| Horse Radish Sauce 🥬 | ½ cup | Prepared or homemade with fresh grated |
| Yellow Mustard 🟡 | ¼ cup | Classic American-style preferred |
| Neutral Oil 🫒 | 1 tbsp | Avocado or grapeseed for high-heat searing |
| Water 💧 | 2 cups | Filtered for clean au jus base |
The beef selection is paramount for replicating Arby’s texture. Top round or bottom round roast provides the ideal lean-to-fat ratio, ensuring sliceability without excessive shrinkage. Source from Costco or Whole Foods for consistent quality, requesting a cut with minimal connective tissue. The Diamond Crystal kosher salt is specified for its clean flavor and precise measurement properties—substituting table salt requires a 50% reduction by volume. For the bouillon, Better Than Bouillon brand offers superior depth without artificial aftertaste, available in the soup aisle of most major grocers.
Substitutions must maintain the flavor architecture: Worcestershire sauce (1 tbsp) can replace half the bouillon for umami complexity, though it introduces sodium variability. Should sesame buns prove elusive, potato rolls offer comparable softness when lightly toasted. The horseradish sauce demands freshness—Heinz prepared horseradish provides consistent heat, while homemade requires freshly grated root (2 tbsp grated + 1/2 cup mayo + 1 tsp vinegar). For smoke depth without paprika, 1/4 tsp liquid smoke in the au jus achieves similar effect, though use sparingly to avoid bitterness.
Storage protocols preserve texture and safety: the roasted beef maintains optimal tenderness when cooled in its juices, then refrigerated in an airtight container for up to 5 days. Au jus separates when chilled; reheat gently with continuous whisking to re-emulsify. For longer preservation, vacuum-seal beef slices with parchment between layers and freeze for 3 months. The seasoning blend remains potent for 6 months in a dark pantry, while prepared horseradish sauce holds 10 days refrigerated in a glass jar.

Step-by-Step Instructions for Arby’s-Style Roast Beef
Mastering this technique requires precision in seasoning, slow roasting, and proper resting for maximum tenderness.
Step 1: Prepare and Season the Beef Round Roast
Begin by patting the 3.5 lb beef round roast completely dry with paper towels. This step is crucial for achieving proper browning during the searing process. Trim any remaining excess fat from the surface, leaving only a thin layer to protect the meat during cooking.
In a small bowl, combine the 1.5 tbsp kosher salt, 1 tbsp coarsely ground black pepper, 1 tbsp garlic powder, 1 tbsp onion powder, 1 tsp smoked paprika, and 1 tsp dried thyme. Rub this mixture evenly over all surfaces of the roast, pressing gently to ensure adhesion. Let the seasoned roast sit at room temperature for 30 minutes before cooking to allow the flavors to penetrate.
Step 2: Sear and Slow Roast the Beef
Preheat your oven to 250°F. Heat the 1 tbsp neutral oil in a large Dutch oven over medium-high heat until shimmering. Add the seasoned roast and sear on all sides until a deep brown crust forms, about 3-4 minutes per side. This searing process develops the Maillard reaction, creating complex flavors that will carry through the final dish.
Once seared, transfer the Dutch oven to the preheated oven. Add the 2 cups water to the pot, being careful not to pour it directly over the meat. Cover tightly and roast for 3-4 hours, or until the internal temperature reaches 195-200°F for optimal tenderness. The low-and-slow method breaks down connective tissues while preserving moisture.
Step 3: Prepare the Au Jus
Carefully remove the roast from the Dutch oven and transfer to a cutting board, reserving all cooking liquids. Skim off any excess fat from the surface of the cooking liquid. In a small bowl, create a slurry by whisking together the 1 tbsp all-purpose flour with 2 tbsp unsalted butter until smooth.
Place the Dutch oven with cooking liquids over medium heat and bring to a gentle simmer. Whisk in the butter-flour slurry and continue simmering for 5-7 minutes until the au jus thickens slightly and develops a rich, glossy appearance. Stir in the 2 tbsp beef bouillon powder and adjust seasoning if needed. The finished au jus should coat the back of a spoon lightly while maintaining a pourable consistency.
Step 4: Slice and Assemble the Sandwiches
Using a sharp slicing knife, cut the roast beef against the grain into thin slices, approximately ⅛-inch thick. The meat should be tender enough to pull apart easily with minimal resistance. Arrange the slices on a platter and ladle some of the warm au jus over them to keep them moist while assembling the sandwiches.
Toast the 6 sesame seed buns until golden brown. Spread the bottom half of each bun with 0.25 cup yellow mustard and the top half with 0.5 cup horse radish sauce. Pile the sliced beef generously on the bottom buns, spoon additional au jus over the meat, and cover with the top buns. Serve immediately while the beef is still warm and the buns are crisp.
Pro Tips For Making Arbys
- Dry the Roast Overnight: Pat the beef round completely dry, then leave it uncovered in the fridge for 12+ hours—sounds weird, but it guarantees a crust that actually cracks when you bite into it. I skipped this step for years and my “Arby’s-style” roast always tasted steamed instead of seared.
- Double the Seasoning: Use 1 tablespoon kosher salt per pound of meat, plus heavy-handed shakes of black pepper, garlic, and onion powder—it seems like overkill until you taste how much flavor the long, slow cook soaks up. My first attempt was underseasoned, and I ended up salting every slice after the fact.
- Pull at 130°F, Not 145°F: Take the roast out when it hits 130°F internal temp—it’ll coast up to medium (140-145°F) while resting, and you avoid the dry, chalky texture that ruins cheap cuts like bottom round. I ruined two roasts waiting for “official” doneness temps before learning this the hard way.
- Slice Against the Grain, Then Pile: After resting, cut thin slices perpendicular to the muscle fibers (look for the long lines in the meat), then stack them back together before serving—this mimics Arby’s texture exactly. My early attempts were chewy until I realized I’d been slicing with the grain like a steak.
Wine and Beer Pairings for This Dish
Classic Beer Pairings
The rich, savory flavors of this roast beef demand a beer with enough body to stand up to the meat. I always reach for a classic American amber lager like Yuengling Traditional Lager—its caramel notes complement the beef’s depth while the crisp finish cuts through the au jus. For something lighter, a German pilsner like Warsteiner offers clean, refreshing contrast. 🍺
Bold Stout Options
If you prefer darker beers, a dry Irish stout such as Guinness works surprisingly well. The roasted malt flavors echo the beef’s caramelized crust, while the creamy texture balances the horseradish’s kick. I like to serve it slightly chilled—around 45°F—to let the flavors shine without overpowering the sandwich.
Crisp Lager Choices
For a no-fuss pairing that everyone enjoys, grab a Mexican lager like Modelo Especial. The light citrus notes and effervescence cleanse your palate between bites, making each mouthful taste as good as the first. I keep a six-pack in the fridge specifically for roast beef nights—it’s that reliable.
Wine Pairings
Red wine lovers should opt for a medium-bodied Cabernet Sauvignon from California—Josh Cellars offers great value. The tannins soften against the beef’s richness, while dark fruit flavors harmonize with the au jus. Serve at 60-65°F to let the wine’s complexity unfold without overwhelming the meal.
White Wine Alternative
Surprisingly, a dry Riesling like Dr. Loosen Blue Slate works beautifully. Its bright acidity cuts through the meat’s richness, and the subtle mineral notes complement the seasoning blend. I discovered this pairing at a wine tasting and now keep a bottle specifically for roast beef sandwiches. ✨
Non-Alcoholic Options
For a zero-proof pairing, try sparkling apple cider—Martinelli’s Gold adds festive bubbles that refresh your palate. The natural sweetness balances the horseradish’s heat, while the effervescence mimics the cleansing effect of beer. Serve well-chilled in wine glasses for an elegant touch.

Frequently Asked Questions
What’s the best cut of beef for this recipe?
Use top round or bottom round roast for the closest texture to Arby’s. These cuts are lean but become tender when slow-roasted at 250°F for hours. Avoid fattier cuts like chuck—they won’t slice as cleanly.
Can I make this in a slow cooker instead?
Yes! Sear the beef first, then cook on LOW for 8-10 hours with the same seasoning and 2 cups water. The texture will be slightly different but still delicious. Skip the Dutch oven step entirely.
How do I get the meat to slice thinly like Arby’s?
Chill the cooked roast for 1-2 hours before slicing—this firms up the meat. Use a long, sharp slicing knife and cut against the grain at a ⅛-inch thickness. A meat slicer works best if available.
What if I don’t have smoked paprika?
Substitute with ½ tsp regular paprika + ¼ tsp liquid smoke. Alternatively, add ½ tsp ground cumin for warmth without the smoky note. The flavor won’t be identical but will still be tasty.
How long can I store the leftovers?
Keep sliced beef and au jus in separate airtight containers for up to 5 days in the fridge. Reheat gently in the au jus to prevent drying. For longer storage, freeze for 3 months.
