Ingredients for arbys roast beef copycat
Six key ingredients transform simple beef into iconic Arby's-style sandwiches with restaurant-quality au jus.
| Ingredient | Amount | Notes |
|---|---|---|
| Beef Top Round Roast 🥩 | 4 lb | Well-marbled, 2-3 inches thick |
| Yellow Onion 🧅 | 1 whole | Quartered, for au jus |
| Carrot 🥕 | 2 whole | Chopped, for au jus |
| Celery Stalks 🌿 | 3 whole | Chopped, for au jus |
| Garlic Cloves 🧄 | 6 cloves | Smashed, for au jus |
| Beef Broth 💧 | 2 cups | Low-sodium preferred |
| Worcestershire Sauce 🍶 | 1 tbsp | For depth of flavor |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Bread Rolls 🍞 | 12 whole | Soft hoagie rolls, sliced |
| Mayonnaise 🥫 | ½ cup | For spreading on buns |
| Dijon Mustard 🍯 | 1 tbsp | For bun spread |
| Beef Fat (from roast) 🫒 | ½ cup | Reserved from roasting |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
The beef cut matters—top round roast delivers the perfect balance of tenderness and fat for that signature texture. Look for a well-marbled cut with visible fat streaks, about 2-3 inches thick for even roasting. Costco or local butcher shops often carry this cut pre-trimmed, but if buying whole, trim excess fat to about 1/4-inch thickness. The fat renders during roasting, creating that rich au jus. For best results, let the roast sit at room temperature for 30 minutes before cooking—this ensures even doneness throughout. If you're short on time, a 24-hour marinade in beef broth and Worcestershire sauce can enhance tenderness, though it's not required.
No Worcestershire sauce? A splash of soy sauce plus a pinch of sugar mimics the umami depth. The au jus vegetables—onion, carrot, and celery—should be chopped uniformly for even cooking. Baby carrots or pre-chopped mirepoix mixes save time here. For the buns, soft hoagie rolls work best—they hold up to the wet filling without getting soggy. If you can't find them, Italian bread rolls toasted lightly also work. The reserved beef fat is crucial—it adds richness to the au jus. If you accidentally discard it, add 1 tbsp butter to the au jus at the end. For the mayo spread, Duke's or Hellmann's are reliable, but any good-quality mayo will do. The Dijon mustard adds a tangy contrast that's essential for balancing the rich beef.
Roast the beef uncovered for even browning, then tent loosely with foil to retain moisture. The au jus should reduce to a syrupy consistency—simmer uncovered for the last 10 minutes to thicken. Store leftovers in airtight containers for up to 4 days, with the au jus layered on top to keep the beef moist. For freezing, portion the sandwiches individually—they reheat beautifully in a skillet with a splash of au jus. The au jus also freezes well for up to 3 months, making it perfect for future sandwiches or as a quick pan sauce. Garnish with fresh parsley just before serving to keep it vibrant—it wilts quickly, so add it last.

Step-by-step instructions for Arbys roast beef copycat recipe
Master this iconic sandwich technique with restaurant-quality roast beef and rich au jus.
🔥 Step 1: Sear and Roast the Beef Top Round
Preheat your oven to 300°F. Pat the 4 lb Beef Top Round Roast dry with paper towels—this ensures maximum browning. In a large Dutch oven, heat 0.5 cup Beef Fat (from roast) over medium-high heat until shimmering. Sear the roast on all sides for 3-4 minutes per side until deeply browned. This creates that signature caramelized crust.
Remove the roast from the Dutch oven and place it on a cutting board. Pour the rendered beef fat into a measuring cup—you should have about 0.5 cup. Return the Dutch oven to the stovetop over medium heat and add the 1 whole Yellow Onion, 2 whole Carrot, 3 whole Celery Stalks, and 6 cloves Garlic Cloves. Sauté for 5 minutes until softened. Deglaze with 2 cups Beef Broth and 1 tbsp Worcestershire Sauce, scraping up all the browned bits.
Transfer the roast to the Dutch oven, fat-side up. Cover and transfer to the preheated oven. Roast for 2.5-3 hours until the internal temperature reaches 195°F and the meat is fork-tender. The au jus should reduce to a rich, syrupy consistency—this is your secret weapon for that signature Arbys flavor.
🍳 Step 2: Prepare the Au Jus and Rest the Meat
Remove the roast from the oven and let it rest in the Dutch oven for 15 minutes. While it rests, strain the au jus through a fine-mesh sieve into a clean saucepan. Season with 1.5 tsp Kosher Salt and 0.5 tsp Ground Black Pepper. Simmer over medium-low heat for 5-7 minutes until slightly thickened. The au jus should coat the back of a spoon with a glossy sheen—this is your flavor base.
Transfer the roast to a cutting board and let it rest for an additional 15 minutes before slicing. This resting period allows the juices to redistribute, ensuring each slice remains moist and flavorful. The meat should be so tender it practically falls apart with gentle pressure—this is the hallmark of a perfect Arbys-style roast beef.
👨🍳 Step 3: Assemble the Bun Bites
Slice the 12 whole Bread Rolls in half horizontally, creating 24 halves. Spread each half with a mixture of 0.5 cup Mayonnaise and 1 tbsp Dijon Mustard, using about 1 teaspoon per bun half. The mayonnaise adds creaminess while the Dijon mustard provides a subtle tang that complements the beef.
Slice the rested roast beef against the grain into ¼-inch thick slices. Place 2 slices of beef on each bun half, slightly overlapping for that classic Arbys look. Ladle 1 tablespoon of the warm au jus over each beef slice—this is where the magic happens. The au jus should be hot enough to slightly soften the bread without making it soggy.
🥘 Step 4: Serve Immediately with Garnish
Garnish each sandwich with 1 teaspoon of the chopped 0.25 cup Fresh Parsley for a pop of color and freshness. Serve immediately while the au jus is still warm and the bread is slightly toasted. The combination of tender beef, rich au jus, and soft bun creates that iconic Arbys experience right in your kitchen.
For the best results, assemble these sandwiches just before serving. The au jus will continue to soak into the bread, creating that perfect balance of moisture and texture. Each bite should deliver layers of flavor—savory beef, tangy mustard, creamy mayo, and that unmistakable au jus that makes this copycat recipe so special.
Pro Tips For Making Arbys Roast Beef Copycat
- USE A MEAT THERMOMETER: I learned this the hard way—top round roast can turn dry if you guess at doneness. Aim for 130°F internal temp (it’ll rise to 135°F while resting), and don’t pull it early just because it looks cooked. The sauce needs something tender, not rubbery.
- SWEAT THE VEGETABLES LOW AND LONG: High heat burns onions and carrots before they soften. Cook them on medium-low with a splash of water until the onions are translucent and carrots are fork-tender—about 12-15 minutes. This builds flavor without bitterness, and you’ll actually need less salt later.
- SKIP THE CROWDED POT: I used to dump everything in at once, and the beef would steam instead of sear. Brown the roast first, then remove it and cook the veggies in the same pot until they’re soft. Add the beef back in with the broth—this ensures the veggies don’t turn to mush and the roast stays juicy.
- REST THE ROAST UNDER FOIL: Cutting into it straight from the pot is a rookie move. Transfer the roast to a plate, loosely tent with foil, and let it sit for 10 minutes. This keeps it from falling apart when you slice it, and the residual heat finishes cooking it evenly—no more dry edges.
Flavor customization for this arbys roast beef copycat
Spice Level Boost
For a kick, add ½ teaspoon smoked paprika and ¼ teaspoon cayenne pepper to the au jus while simmering. This mirrors Arby's occasional spicy roast beef variations without overpowering the beef's natural flavor. I like to add a pinch of ground cumin for depth—just ⅛ teaspoon—it enhances the earthiness beautifully. 🌶️
Sweet Heat Twist
Balance the richness with a honey glaze by adding 1 tablespoon honey to the au jus during the final 5 minutes of simmering. This creates a caramelized finish that pairs perfectly with the beef. For extra flair, drizzle 1 teaspoon of the honey-glazed au jus over each sandwich just before serving. Trust me, this adds a restaurant-worthy touch!
Herb-Infused Variations
Swap the parsley garnish for chopped fresh thyme or rosemary to elevate the flavor profile. Add 1 sprig of each herb to the au jus while simmering, then remove before serving. For a Mediterranean twist, use fresh oregano—it adds a bright, citrusy note that cuts through the beef's richness. Always add herbs fresh at the end to preserve their vibrant color and aroma.
Cheesy Upgrade
Add ¼ cup shredded sharp cheddar cheese to the au jus during the final 2 minutes of simmering. The cheese melts into a creamy, tangy sauce that clings perfectly to the beef. For a smoky option, use smoked Gouda—it adds depth without overpowering. Sprinkle 1 tablespoon of the cheesy au jus over each sandwich for an indulgent twist.
Classic BBQ Fusion
Mix 2 tablespoons of your favorite BBQ sauce (I recommend Sweet Baby Ray's Original) into the au jus for a sweet-smoky fusion. This works especially well with a ½ cup BBQ sauce drizzle on the assembled sandwiches. For a tangier kick, use Sticky Fingers Carolina Gold—it adds a vinegar-based punch that balances the beef beautifully. 🔥
Gourmet Garnishes
Elevate your sandwiches with pickled jalapeños or quick-pickled red onions for a tangy crunch. Slice 2 jalapeños into rings and pickle them in ½ cup vinegar, 1 teaspoon sugar, and ½ teaspoon salt for 10 minutes before serving. For extra flair, add toasted sesame seeds or crushed black pepper on top—these add texture and visual appeal without overpowering the beef.

Frequently asked questions
Why does the beef need to rest for so long?
Resting the beef for 15 minutes after roasting is critical—it lets the juices redistribute throughout the meat instead of pouring out when sliced. This ensures each bite stays tender and moist, just like Arby's version. Skipping this step often results in dry, tough slices that lack that signature melt-in-your-mouth quality.
Can I use a different cut of beef?
While top round roast is ideal, you can substitute with chuck roast or bottom round—just increase roasting time by 30-45 minutes since these cuts need more time to tenderize. Avoid lean cuts like sirloin—they won't develop the same rich au jus. For best results, choose a cut with visible fat marbling.
How do I fix soggy buns?
Soggy buns happen when the au jus is too hot or the bread isn't fresh. To prevent this, use soft but slightly stale rolls (toasted lightly) and assemble sandwiches just before serving. If the buns still get soggy, try toasted Hawaiian rolls or potato rolls—they hold up better. For extra insurance, brush the buns with egg wash before toasting.
Can I make this ahead of time?
Roast the beef and make the au jus up to 3 days ahead—store in airtight containers with the au jus layered on top to keep it moist. Reheat in a skillet with a splash of au jus. For sandwiches, assemble them 1 hour before serving (cover with a damp towel) to let flavors meld. Never refrigerate assembled sandwiches—they'll get soggy.
What's the secret to perfect au jus?
The au jus needs to be syrupy but not gluey—simmer it uncovered for the last 10 minutes to reduce it properly. The key ingredients are the beef fat and Worcestershire sauce, which add depth. If your au jus is too thin, reduce it longer; if too thick, whisk in 1 tablespoon beef broth. Always taste and adjust seasoning before serving.
