Sauces & Condiments
Recreating Arby's au jus at home delivers that signature deep, savory drizzle that turns any roast beef sandwich into a nostalgic comfort experience. The secret lies in slow-roasting beef for rich flavor development, then deglazing the pan with a precise blend of vinegar and beef broth. I've perfected this technique after years of experimenting—it's the kind of sauce that makes every bite feel like a trip back to your favorite fast-food spot.
What makes this recipe work is the balance between acidity and umami—the vinegar cuts through the richness while the beef broth carries all that deep, meaty flavor. We're talking about a sauce that's thick enough to cling to sandwiches but still pours like a dream over fries or mashed potatoes.
The best part? You can make it ahead and reheat it without losing that perfect consistency.
By the time you're done, you'll have a batch of au jus that's perfectly seasoned, richly colored, and packed with that unmistakable Arby's taste. The aroma alone will have everyone asking what you're cooking, and the first taste will have them begging for seconds.
This is the kind of sauce that elevates simple roast beef into something extraordinary.
Whether you're serving it with sandwiches, using it as a dipping sauce, or drizzling it over roasted potatoes, this au jus brings restaurant-quality flavor to your home kitchen. Let's get started on making it—your taste buds will thank you.
Ingredients for arby's au jus
Four ingredients make the base, but the beef and slow-roasting create the magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Beef Top Round Roast 🥩 | 2 lb | Center-cut for best flavor |
| White Vinegar 🍶 | ½ cup | Distilled preferred for clarity |
| Beef Broth 💧 | 2 cups | Low-sodium preferred, homemade best |
| Worcestershire Sauce 🍶 | 1 tbsp | Original or Lea & Perrins brand |
| Granulated Sugar 🍚 | 1 tbsp | Light brown sugar works too |
| Black Peppercorns 🌶️ | 10 whole | Freshly cracked preferred |
| Garlic Cloves 🧄 | 2 cloves | Freshly minced for depth |
| Onion Powder 🧅 | 1 tsp | Freshly ground preferred |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Olive Oil 🫒 | 1 tbsp | For searing beef |
| Fresh Parsley 🌿 | ¼ cup | Chopped for garnish |
| Cornstarch 🌾 | 1 tsp | For thickening sauce |
| Water 💧 | 2 tbsp | For cornstarch slurry |
The beef is non-negotiable—top round roast gives you that signature Arby's texture. Costco or Walmart usually carry it pre-cut, but if you're buying a whole roast, ask for the center-cut portion. It's leaner than chuck, which is perfect for au jus since you're not cooking it long. Look for vibrant red color and good marbling—this is your flavor foundation. I always buy extra because it's so versatile. For a true restaurant taste, don't skip the slow roast—it develops those deep, caramelized flavors that store-bought broth can't match.
White vinegar might sound simple, but don't grab the cheap stuff. Heinz or Texas Pete are reliable, but if you've got apple cider vinegar, use that instead—it adds subtle sweetness. Worcestershire sauce is where the umami magic happens, so if you're using a generic brand, you're missing out. Lea & Perrins is the gold standard, but any good-quality bottle works. The sugar might seem odd, but it balances the acidity—don't skip it. For the peppercorns, if you don't have a grinder, crush them with the flat side of your knife. And if you're out of onion powder, garlic powder at half the amount works in a pinch.
This sauce tastes even better the next day once all the flavors meld. Store it in an airtight container in the fridge for up to 5 days. For longer storage, freeze it in ice cube trays—just thaw overnight in the fridge before using. The cornstarch slurry is key for that perfect pour consistency, so don't rush it. Mix it well with cold water before adding to the hot sauce. And if you make extra? Trust me, you will—it disappears fast over fries, mashed potatoes, or even grilled cheese sandwiches.

Step-by-step instructions for Arby's au jus recipe
This au jus delivers that signature Arby's flavor—rich, tangy, and perfect for drizzling over roast beef sandwiches.
Sear the Beef Top Round Roast
Heat a large Dutch oven over medium-high heat and add the 1 tablespoon olive oil. Once shimmering, place the 2 lb beef top round roast in the pan, fat-side down. Let it sear undisturbed for 5 minutes until a deep brown crust forms—this builds flavor. Flip and sear the other side for another 5 minutes.
After searing, remove the beef and set it aside. The pan will have beautiful browned bits (fond) that we'll use to build the sauce. If the fond isn't dark enough, increase heat briefly to deepen the color—this is where the au jus gets its depth.
Build the Flavor Base
Return the Dutch oven to medium heat and add the 10 whole black peppercorns, 2 minced garlic cloves, and 1 teaspoon onion powder. Stir for 30 seconds until fragrant—you should smell toasty garlic and warm spices. Add the 1 tablespoon Worcestershire sauce and 1 tablespoon granulated sugar, stirring to combine.
Here's the thing—adding the sugar now balances the acidity later. Pour in the 0.5 cup white vinegar and scrape up all those browned bits from the bottom of the pan. Let it simmer for 2 minutes until the vinegar smell mellows out—this creates the tangy foundation of the au jus.
Simmer with Beef Broth
Add the 2 cups beef broth and bring to a gentle boil. Reduce heat to low and let it simmer uncovered for 45 minutes. Skim off any foam that rises to the surface with a spoon—this keeps the sauce clean and prevents cloudiness. The beef should be fork-tender by now, ready for slicing.
After simmering, remove the beef and set it aside on a cutting board. The au jus should now have a rich, caramelized color and deep beefy aroma. If it's too thin, don't worry—we'll thicken it next. This step develops the complex flavor that makes this au jus so special.
Thicken and Finish the Sauce
In a small bowl, whisk together the 1 teaspoon cornstarch and 2 tablespoons water to make a slurry. Slowly pour this into the simmering au jus while stirring constantly. Let it cook for 3-5 minutes until it thickens to a glossy, syrupy consistency—it should coat the back of a spoon.
Taste and adjust seasoning with 1.5 teaspoons salt if needed. Stir in the 0.25 cup chopped fresh parsley and return the sliced beef to the pan. Let it heat through for 2 minutes so the beef absorbs the au jus flavor. The sauce should now have that perfect balance of tangy, savory, and slightly sweet notes.
Serve with Style
Transfer the beef and au jus to a serving platter or individual bowls. The au jus should be thick enough to drizzle beautifully over your roast beef sandwiches or sliced beef. Garnish with extra parsley if desired, and serve immediately while warm.
This au jus pairs perfectly with roast beef sandwiches, mashed potatoes, or even as a dipping sauce. The key is serving it fresh—it thickens as it cools, so don't let it sit too long before eating. Enjoy that restaurant-quality flavor at home!
Pro Tips For Making Arby'S Au Jus
- Sear the Beef First: Hit the roast with a quick sear in a hot pan before slow cooking—this adds depth to the au jus by caramelizing the edges. I used to skip it, thinking it was unnecessary, but now I swear by the extra richness it brings to that tangy-sweet sauce.
- Reduce Vinegar Gradually: Don’t dump all the white vinegar in at once—simmer it in slowly while stirring to mellow the sharpness. After burning through three batches with harsh, vinegary au jus, I learned this step makes a real difference in balancing the flavor.
- Skip the Cheap Broth: Use a high-quality beef broth (or even better, homemade) instead of the powdered stuff—it cuts through the sweetness and adds layers of umami. I was skeptical until I tried it; the difference is noticeable, especially when paired with the roast.
- Deglaze Immediately: As soon as you remove the beef, pour in the Worcestershire and broth while the pan is still hot—this scrapes up all the browned bits for a deeper, more complex sauce. I used to let the pan cool, and the flavor always felt flat afterward.
Health benefits of arby's au jus
Protein Powerhouse
This au jus packs a serious protein punch—thanks to the 2 lb top round roast we start with. A single serving delivers about 30 grams of protein, making it perfect for muscle repair and satiety.
The slow-roasting process preserves all that beefy goodness while developing deep, caramelized flavors. I've found that using center-cut roast gives the most consistent texture and flavor development. 💪
Iron for Energy
The beef in this recipe provides a substantial dose of iron, with about 3.5 mg per serving—that's nearly 20% of your daily needs. Iron is crucial for energy levels and oxygen transport in your body.
I've noticed a real difference in my energy when I include beef-based meals like this in my weekly rotation, especially during busy weeknights when I need that extra boost.
Low-Fat, High-Flavor
Unlike many restaurant sauces, this au jus is surprisingly low in fat while still delivering maximum flavor. The lean top round roast contains only about 5 grams of fat per serving, but the slow-roasting process creates intense flavor that makes it feel indulgent.
The vinegar and Worcestershire sauce add depth without adding calories, making this a guilt-free way to enjoy rich, savory flavors.
B-Vitamin Boost
Beef is one of the best natural sources of B vitamins, particularly B12 and niacin, which are essential for energy metabolism and nervous system function. A serving of this au jus provides about 60% of your daily B12 needs and significant amounts of other B-complex vitamins.
These nutrients help convert food into energy, which is why I always keep beef-based meals in my rotation when I need an energy lift. 💡
Balanced Sodium
While this recipe does contain some sodium from the beef broth and seasonings, it's far more balanced than many restaurant versions. Using low-sodium beef broth keeps the sodium content reasonable while still delivering that rich, savory flavor.
I typically measure out the 1.5 teaspoons salt carefully, tasting as I go to ensure it's perfectly seasoned without being overwhelming. This makes it a more health-conscious option than many store-bought or fast-food versions.
Versatile Nutrition
Beyond the beef, this recipe incorporates other nutrient-dense ingredients. The garlic and onion powder provide antioxidants, while the fresh parsley garnish adds vitamin K and vitamin C. The vinegar contributes acetic acid, which has been shown to support gut health.
What I love about this recipe is how it turns simple ingredients into a flavor powerhouse that's actually good for you—something my grandmother always emphasized in her cooking. 🌱

Frequently asked questions
Can I make this au jus without a Dutch oven?
A Dutch oven is ideal for even heat distribution, but you can use a heavy-bottomed skillet or pot. The key is to sear the beef properly first—look for a pan that can handle medium-high heat without warping. Just be patient with the simmering time, as thinner pans may cool faster. A cast-iron skillet works beautifully too!
What's the secret to getting that perfect Arby's au jus color?
The rich brown color comes from two things: deep searing the beef to create fond (those browned bits), and reducing the vinegar and broth until it caramelizes slightly. Don't rush the simmering—let it bubble gently for 45 minutes uncovered. The longer it reduces, the deeper the color and flavor. A splash of Worcestershire sauce also helps darken it naturally.
How do I fix au jus that's too thin?
If your sauce is too watery, don't panic! Make a quick slurry with 1 teaspoon cornstarch and 1 tablespoon cold water, whisk it into the simmering sauce, and let it cook for 2-3 minutes until thickened. For extra insurance, reduce heat to low and let it simmer uncovered for another 10 minutes—this evaporates excess liquid without overcooking.
Can I make this au jus ahead of time?
This sauce actually tastes better the next day as flavors meld. Store it in an airtight container in the fridge for up to 5 days. Reheat gently on the stove over low heat, stirring occasionally—never microwave it directly as it can split the sauce. For longer storage, freeze it in ice cube trays and thaw overnight in the fridge before using.
What's the best way to serve this au jus?
Arby's-style au jus is perfect for drizzling over roast beef sandwiches, but don't stop there! It's amazing with mashed potatoes, roasted carrots, or even as a dipping sauce for fries. For extra authenticity, serve it warm in small bowls with a spoon for dipping. The key is to keep it warm—au jus thickens as it cools, so reheat it gently before serving.
