Arby's Au Jus Recipe: Deep, Savory Beef Broth for Homemade Copycat Drizzle

This Arby's au jus recipe delivers that signature deep, savory beef broth you crave with every bite of their famous roast beef sandwich. 💛 I've recreated it after years of testing, and the secret lies in slow-roasting beef with aromatic spices while building the sauce from scratch—no shortcuts.

The result? A rich, caramelized drizzle that's worth the effort.

The key to authentic flavor is patience: roasting a chuck roast until fork-tender while developing the au jus simultaneously. No beef broth here—just the natural juices concentrated with garlic, Worcestershire, and a touch of brown sugar. This method ensures every spoonful captures that iconic Arby's taste without artificial additives.

By the time you're done, you'll have perfectly sliced roast beef with a glossy, dark au jus that clings to every bite. The sandwich assembly is simple—just layer the beef between toasted buns with your favorite toppings—but it's that homemade au jus that transforms it into something restaurant-quality.

Let's get started!

Pro tip: Make a double batch of au jus—it reheats beautifully and elevates grilled steak or burgers just as well. The leftovers keep for 5 days in the fridge, so you'll have this copycat sauce on hand whenever cravings strike. Now for the step-by-step instructions!

Ingredients for arby's au jus

Pantry staples plus a few specialty touches—this is how you nail Arby's au jus at home.

The chuck roast is your secret weapon—bone-in for maximum flavor, and Costco or Whole Foods carry the best cuts. Look for good marbling, not lean meat. I always ask the butcher to cut it into 1-inch chunks for even cooking. The onions and garlic? Yellow onions add sweetness, while garlic cloves should be smashed—not minced—to release their oils slowly. For Worcestershire, Lea & Perrins is the gold standard, but any good brand works. The brown sugar here isn't for sweetness—it's for caramelization, so don't skip it.

No Worcestershire? Soy sauce plus a pinch of sugar gets you close, though it won't be identical. Fresh peppercorns are non-negotiable—pre-ground loses its punch. The bay leaves might seem optional, but they're key for that deep, savory note. Trader Joe's sells them pre-packaged, which saves time. For the balsamic vinegar, aged balsamic (the syrupy kind) adds complexity. If you're making a double batch, double the water too—this au jus reheats beautifully and even improves overnight as flavors meld.

This au jus keeps for 5 days in the fridge, but it's best used within 3 days for peak flavor. Store it in a sealed container with a splash of water or oil on top to prevent a skin from forming. For freezing, portion into ice cube trays—6-12 months in the freezer, and they thaw in seconds. Pro tip: Use the leftover roast beef for sandwiches, and save the au jus for drizzling over burgers or steak. The sesame oil and parsley are just for garnish, but they add that final restaurant-quality touch.

Step-by-step instructions for Arby's au jus copycat drizzle

This method delivers that signature Arby's au jus—rich, savory, and perfect for dipping.

Pat the 3 lb chuck roast completely dry with paper towels—this ensures a proper sear. Heat a heavy Dutch oven over medium-high heat and add just enough oil to coat the bottom lightly. Once shimmering hot, add the roast and sear for 4-5 minutes per side until deeply browned. You're building flavor here, so don't rush—look for a dark mahogany crust that releases easily from the pan.

Once browned, remove the roast and set it aside. The seared meat will release its juices into the pan, creating the foundation for your au jus. This step is non-negotiable—it's what gives that authentic Arby's depth of flavor. If you see any browned bits sticking, use a wooden spoon to scrape them into the pan for maximum flavor extraction.

In the same Dutch oven, add 1 whole yellow onion sliced into wedges and 6 peeled, smashed garlic cloves. Cook for 5-6 minutes until the onions soften and turn golden. You want them caramelized but not burnt—this adds sweetness that balances the savory notes. Stir occasionally to prevent sticking, but don't overcrowd the pan.

Add 1 tsp black peppercorns, 2 whole bay leaves, and 1 tsp salt, stirring to coat everything evenly. These spices will infuse the broth with warmth and complexity. Pour in 1 cup water and scrape up any browned bits from the bottom of the pan—this is where all the magic happens. Let it simmer gently for 10 minutes to allow the spices to bloom and release their flavors.

Return the seared chuck roast to the Dutch oven. Add 2 tbsp Worcestershire sauce, 2 tbsp brown sugar, and 1 tbsp balsamic vinegar. The Worcestershire brings umami depth, the brown sugar adds a subtle caramel note, and the balsamic vinegar gives that signature tang. Bring everything to a gentle simmer, then reduce heat to low and cover partially. Let it cook for 2-2.5 hours, turning the roast occasionally.

Here's the thing—you're not just cooking the roast, you're rendering fat and extracting collagen from the meat. This creates a naturally thick, velvety broth. The roast should be fork-tender when done, and the liquid should have reduced significantly but still coat the back of a spoon. If it reduces too quickly, add 2-3 tbsp water to maintain the proper consistency.

Once the roast is tender, remove it from the Dutch oven and strain the cooking liquid through a fine-mesh sieve into a clean saucepan. You'll have about 2-2.5 cups of rich, flavorful broth. Return this to the stove over medium-low heat and add 1 tbsp beef topping. Stir constantly for 3-4 minutes until the topping dissolves completely and the sauce thickens slightly.

For the finishing touch, stir in 0.5 tsp toasted sesame oil—this adds a subtle nutty aroma that mimics the Arby's signature. Taste and adjust seasoning with additional salt or Worcestershire sauce if needed. The au jus should be rich, slightly sweet, and deeply savory with just a hint of tang. Let it cool slightly before using—it will thicken as it sits.

Let the au jus cool to room temperature, then transfer it to an airtight container. It will keep in the refrigerator for up to 5 days or in the freezer for up to 3 months. When ready to use, reheat gently over low heat, stirring occasionally until warmed through. For the best texture, don't boil it—just warm until it reaches 160°F.

This au jus is perfect for dipping Arby's-style curly fries, drizzling over beef sandwiches, or even using as a marinade. The beauty of homemade is that you can adjust the sweetness or tang to your preference. I like to keep a jar in my fridge at all times—it's the secret weapon that takes any beef dish to the next level. Serve immediately for the ultimate copycat experience!

Troubleshooting this recipe

Too Thin or Watery

If your au jus turns out too thin, it’s usually because you didn’t reduce the liquid enough during cooking. The key is patience—simmer uncovered for an extra 15-20 minutes to thicken it naturally.

For a quick fix, mix 1 tbsp cornstarch with 2 tbsp cold water, stir into the hot sauce, and cook for 2-3 minutes until it thickens. I’ve also had success adding 1-2 tbsp beef topping (like the kind for meatloaf) to bind the sauce slightly. 💡

Too Sweet or Overpowering

The brown sugar in this recipe is meant to caramelize, not dominate. If your au jus tastes too sweet, balance it with an extra ½ tsp Worcestershire sauce or 1 tsp balsamic vinegar.

For a deeper savory note, add a pinch of black pepper or a dash of soy sauce. I once accidentally doubled the brown sugar—adding a splash of red wine vinegar saved the day. Taste as you go!

Meat Too Tough or Dry

Overcooking is the usual culprit here. The roast should be fork-tender but still juicy, which means pulling it out at 200-205°F internal temperature. If it’s dry, try slicing thinner and serving with extra au jus.

For next time, add ½ cup beef broth to the pot during the last 30 minutes of cooking to keep it moist. I also recommend resting the roast for 10 minutes before slicing—this lets the juices redistribute. 🥩

Au Jus Too Dark or Burnt

This happens when the onions or garlic brown too much, creating bitter flavors. Keep an eye on them and remove any burnt bits immediately. For a smoother color, strain the au jus through a fine-mesh sieve lined with a coffee filter.

If it’s still too dark, stir in 1 tsp honey or ½ tsp maple syrup to mellow the intensity. I’ve also used a splash of apple cider vinegar to brighten overly caramelized sauces.

Sauce Separates When Reheating

This is normal if the au jus cools too quickly. To fix it, gently reheat over low heat while stirring constantly. If it still separates, whisk in 1 tbsp cold water or beef broth to help emulsify it.

For future batches, store the au jus in a shallow container so it cools evenly. I keep mine in a glass Pyrex dish—it reheats beautifully without separating. ❄️

Lacks That Signature Arby’s Tang

The tang comes from the balsamic vinegar and Worcestershire, but sometimes you need a little extra. Add ½ tsp Dijon mustard or ¼ tsp smoked paprika for depth. I also like a pinch of onion powder to enhance the umami.

If it’s still flat, simmer the sauce for 5 more minutes to concentrate the flavors. Pro tip: A few drops of hot sauce can add the right kick without overpowering. 🌶️
