Arby’s Au Jus Recipe: Savory Beef Broth for Perfect Dipping

This savory au jus delivers the perfect balance of rich beef flavor and subtle seasoning that makes Arby’s famous. I’ve refined this recipe to capture that signature depth without any artificial additives.

The secret lies in a slow simmer that extracts maximum flavor from beef bones and aromatics. A touch of soy sauce enhances the umami, while a splash of vinegar brightens the finish. It’s simpler than you’d expect.

You’ll end up with a deeply flavored broth that’s ideal for dipping roast beef sandwiches or French dip. The aroma alone will have you reaching for a spoon before it even cools.

Make a big batch and keep it on hand for sandwich nights. This version stays true to the classic while being easy to prepare at home.

Ingredients for Arby’s Au Jus

Ten simple ingredients for that classic Arby’s dipping experience at home.

The beef bones are non-negotiable here. Ask your butcher for soup bones—they’re cheap and packed with gelatin that gives au jus its signature body. Whole Foods or local markets often have them pre-cut. Don’t skip the marrow bones if you can get them (that’s where the magic happens). For the soy sauce, Kikkoman low-sodium is my go-to—just enough salt without overpowering.

No beef bones? Beef chuck roast cut into chunks works in a pinch (simmer 3-4 hours). Swap apple cider vinegar for white wine vinegar at the same amount. Out of Worcestershire? A splash of fish sauce or extra soy sauce fills the gap. Fresh thyme is great if you’ve got it—just double the amount. The onion skin adds color, so don’t peel it (weird but true).

This keeps 5 days in the fridge—fat will solidify on top, just skim it off. Freeze in ice cube trays for 6 months (perfect for single sandwich servings). The flavor deepens overnight, so make it a day ahead if you can. Always reheat gently to preserve those delicate aromatics.

Step-by-Step Instructions for Savory Beef Au Jus

Here’s how I make this rich, restaurant-style dipping sauce with deep, beefy flavor every time.

Step 1: Roast the Beef Bones for Maximum Flavor

Preheat your oven to 400°F. Arrange the 2 lb Beef Bones on a baking sheet and roast for 20-25 minutes until deeply browned. This caramelizes the natural sugars in the bones, creating a rich foundation for your au jus.

You’ll know they’re ready when they develop a deep amber color and release a meaty aroma that fills your kitchen. The browning process is crucial—it transforms simple stock into something with real depth.

Step 2: Combine All Ingredients and Simmer

Transfer the roasted bones to a large stockpot. Add the 8 cups Water, 2 tbsp Soy Sauce, 1 tbsp Apple Cider Vinegar, and 1 tbsp Worcestershire Sauce. These three liquid ingredients work together to create that signature Arby’s tang.

Add the 4 cloves Garlic Cloves (smashed), 1 whole Yellow Onion (quarter it, skin on for color), 2 pieces Bay Leaves, 1 tsp Black Peppercorns (lightly crushed), and 1 tsp Dried Thyme. Bring everything to a boil over high heat.

Step 3: Reduce to Concentrated Flavor

Once boiling, reduce the heat to low and let it simmer uncovered for 2-3 hours. You want a gentle simmer, not a rolling boil—this ensures the flavors meld together without becoming bitter.

After about an hour, you’ll notice the liquid darkening and developing a rich, meaty aroma. The volume should reduce by about a third. This concentration is what gives the au jus its intense flavor perfect for dipping.

Skimming any foam that rises to the surface during the first 30 minutes keeps your au jus clear and clean-tasting.

Step 4: Strain and Serve

After simmering, remove the pot from heat and let it sit for 5 minutes to allow the solids to settle. Carefully strain the liquid through a fine-mesh sieve into a clean saucepan, pressing gently on the solids to extract all the flavor.

Discard the solids (they’ve given all their goodness to the liquid). Taste and adjust seasoning if needed—though with the soy sauce and Worcestershire, it should be perfectly balanced. Serve warm in small cups for dipping, or keep warm on the stove over low heat.

Regional Styles of This Recipe

Midwest Classic

In the heartland, this dipping sauce leans into beefy richness. I add 1 extra tbsp Worcestershire and a pinch of smoked paprika to mirror the grilled flavors of Arby’s original location in Ohio. The result is a deeper, more robust profile. 💪

California Light

West Coast versions often brighten the flavor with 1 tbsp lemon juice and ½ tsp red pepper flakes. This nod to fresh, zesty flavors keeps the broth light while still delivering that signature umami depth.

Southern Comfort

Down South, a touch of 1 tsp brown sugar and ½ tsp liquid smoke creates a sweeter, smokier variation. The sugar balances the tang, while the smoke evokes slow-cooked barbecue traditions.

Texas Bold

Everything’s bigger here, including the flavor. I use 3 tbsp soy sauce and 2 tbsp apple cider vinegar for a punchier, more assertive au jus that stands up to hearty Texas-style roast beef.

New England Twist

In the Northeast, a splash of 1 tbsp stout beer and 1 tsp Dijon mustard adds complexity. The beer deepens the savory notes, while the mustard brings a subtle sharpness that’s uniquely regional.
