Ingredients for arby's roast beef sauce
Pantry staples plus a few key ingredients for that signature Arby's kick.
| Ingredient | Amount | Notes |
|---|---|---|
| Ketchup 🍅 | ½ cup | High-quality, smooth variety |
| Fresh Horseradish Root 🌿 | 2 tbsp | Freshly grated, not jarred |
| Mayonnaise 🥚 | ¼ cup | Full-fat preferred for creaminess |
| White Vinegar 💧 | 1 tbsp | For tangy brightness |
| Worcestershire Sauce 🍶 | 1 tbsp | For umami depth |
| Granulated Sugar 🍚 | 1 tbsp | Balances heat and tang |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Garlic Powder 🧄 | ½ tsp | Adds subtle depth |
| Heavy Cream 🥛 | ¼ cup | For velvety texture |
The horseradish is non-negotiable here—freshly grated from the root gives you that signature heat and complexity. Trader Joe's or Whole Foods usually carry the fresh root, but most grocery stores sell it too. If you can't find it, jarred horseradish works in a pinch (though it's less potent). The ketchup matters too—Heinz or Hunt's are solid choices, but any smooth, no-added-sugar version works. For the mayo, Duke's or Hellmann's are reliable, but full-fat is key for that creamy texture.
No fresh horseradish? Hot sauce or extra cayenne can add heat, but it won't be the same. Short on Worcestershire? Soy sauce or a dash of fish sauce adds umami, though Worcestershire is ideal. The sugar balances the heat—brown sugar works too—and the heavy cream gives it that signature velvety finish. Want it thicker? Add a splash more mayo. Too thin? A quick whisk with a bit of cornstarch slurry fixes it instantly.
This sauce keeps beautifully in the fridge for 2 weeks, sealed in an airtight container. The flavors actually deepen after sitting for 30 minutes, so make it ahead if you can. For extra authenticity, strain it through a fine-mesh sieve to remove any horseradish bits. Portion into small jars for easy dipping—perfect for game day or sandwich night.

Step-by-step instructions for Arby's roast beef sauce
This tangy, creamy sauce with a horseradish kick comes together in minutes—no deli counter required.
Grate the Fresh Horseradish Root
Using a box grater or microplane, grate the 2 tablespoons fresh horseradish root into a small bowl. Fresh horseradish delivers that signature sharp, peppery bite that jarred versions can't match. The grated horseradish will release a strong aroma—this is normal and means it's working. If you're sensitive to spice, wear gloves and work in a well-ventilated area.
Set the grated horseradish aside while you measure the remaining ingredients. Don't skip this step—fresh horseradish is the secret to authentic Arby's sauce flavor. If you can't find fresh horseradish root, this recipe won't work as intended with jarred substitutes.
Whisk Together the Base Ingredients
In a medium bowl, combine the 0.5 cup ketchup, 0.25 cup mayonnaise, 1 tablespoon white vinegar, and 1 tablespoon Worcestershire sauce. Use a whisk to blend these ingredients thoroughly for about 30 seconds until they're fully incorporated and smooth. The ketchup and vinegar will create a slightly thick, tangy base that forms the foundation of the sauce.
Next, add the 1 tablespoon granulated sugar, 0.5 teaspoon salt, 0.25 teaspoon black pepper, and 0.5 teaspoon garlic powder. Whisk again until all the dry ingredients dissolve completely. The sugar helps balance the sharpness of the horseradish while the garlic powder adds subtle depth that complements the roast beef flavor.
Fold in the Horseradish and Heavy Cream
Gently fold the grated horseradish into the sauce mixture using a rubber spatula. Start with small amounts to control the intensity—you can always add more if needed. The sauce will take on a vibrant orange color and develop a noticeable kick. Be careful not to overmix, as this could make the sauce too thin.
Finally, stir in the 0.25 cup heavy cream. This adds richness and helps create that signature velvety texture. The heavy cream should blend smoothly, giving the sauce a luxurious mouthfeel. Taste the sauce at this point and adjust the seasoning if needed—you might want to add a pinch more salt or a dash of black pepper to enhance the flavors.
Chill and Let Flavors Develop
Cover the sauce and refrigerate for at least 30 minutes before serving. This chilling time allows the flavors to meld together and the sauce to thicken slightly, creating the perfect consistency. The horseradish's sharpness will mellow just enough to become more palatable while still delivering that signature kick.
When ready to serve, give the sauce a quick stir. It should be smooth, creamy, and ready to elevate your roast beef sandwiches, sliders, or even as a dip for fries. The sauce will keep in the refrigerator for up to 5 days, though it's best enjoyed fresh within the first few days for optimal flavor and texture.
Pro Tips For Making Arby'S Roast Beef Sauce
- GRATE THE HORSRADISH FINE: The pre-packaged stuff is fine, but fresh horseradish grated on the smallest blade of your box grater makes all the difference—it blends smoother and doesn’t leave gritty chunks. If you’re impatient, freeze the root for 15 minutes first; it grates faster and releases the heat more evenly.
- WHISK THE MAYONNAISE FIRST: Don’t just dump everything in the bowl and stir. Whisk the mayonnaise and ketchup together until fully combined before adding the horseradish—this prevents clumping and ensures the heat from the horseradish doesn’t break the mayo’s emulsion. (Yes, I’ve ruined a batch by skipping this.)
- DILUTE THE VINEGAR WITH WATER: Straight white vinegar can overpower the sauce if you’re not careful. Mix it 50/50 with water before adding it to the mix—this keeps the tang bright without making the sauce taste like you’re pickling something. Trust me, your sandwich will thank you.
- TASTE AS YOU GO: This sauce is forgiving, but the balance of sweet (ketchup), heat (horseradish), and umami (Worcestershire) is what makes it sing. Taste after adding the Worcestershire, then again after the vinegar—adjust with a pinch more horseradish or a splash of ketchup if needed. (I learned this after making a batch that tasted like a science experiment.)
Best sauces and condiments for this arby's roast beef sauce
Classic Pairings
This sauce shines best with Arby's-style roast beef sandwiches—drizzle it generously over thinly sliced roast beef on toasted Wonder Bread with a smear of mayo. I like to add a sprinkle of dried parsley for freshness right before serving.
The sauce also works wonderfully as a dip for crispy onion rings or loaded fries, especially when served with a side of Arby's signature beef brisket. 🥪
Spicy Variations
For a hotter kick, add 1 teaspoon of cayenne pepper or ½ teaspoon of red pepper flakes to the base before folding in the horseradish. If you love heat, try swapping 1 tablespoon of the ketchup for sriracha—it adds a sweet-spicy balance that complements the tang.
For a smoky twist, stir in ½ teaspoon of smoked paprika after chilling. 🌶️
Sweet & Tangy Twist
Balance the horseradish heat with a honey or maple syrup glaze—simmer 1 tablespoon of honey with 1 teaspoon of Dijon mustard and brush it lightly over roast beef before adding the sauce. The caramelized sweetness pairs beautifully with the sauce's tang.
Another fun idea? Mix 1 teaspoon of apple cider vinegar into the sauce for a fruity depth that works well with pulled pork sandwiches. 🍯
Creamy Alternatives
If you prefer a lighter texture, swap the heavy cream for Greek yogurt (use ¼ cup full-fat)—it adds protein and a tangy brightness.
For a dairy-free option, replace the mayo and heavy cream with avocado oil mayo and coconut cream, though the flavor will be slightly less rich. Both versions still deliver that signature kick but with a healthier twist. 🥛
Storage & Reuse
Store leftovers in an airtight container in the fridge for up to 2 weeks, though I find it tastes best within 5 days. Freeze portions in ice cube trays for easy single-use servings—just thaw overnight in the fridge.
The sauce also makes a fantastic marinade for grilled meats or a dipping sauce for mozzarella sticks or veggie platters. 🧊
Pro Tips for Perfection
For smoother texture, strain the sauce through a fine-mesh sieve before chilling to remove any horseradish bits. If the sauce separates after refrigerating, whisk in 1 teaspoon of cornstarch mixed with 1 tablespoon water to restore its velvety consistency.
And if you love Arby's sauce on everything, try using it as a glaze for grilled chicken or baked potatoes—it’s a game-changer! 💡

Frequently asked questions
Why does Arby's roast beef sauce need fresh horseradish?
Fresh horseradish delivers that signature sharp, peppery bite that jarred versions can't match. The root contains volatile oils that create the signature kick, while jarred horseradish is pasteurized and loses much of its potency. For the best flavor, always use freshly grated root—it makes all the difference!
Can I make this sauce without mayo or heavy cream?
Yes, but the texture will be thinner. For a lighter version, swap mayo with Greek yogurt (¼ cup) and replace heavy cream with coconut cream for a dairy-free option. The sauce will still have that tangy kick, though it may lack some richness. Adjust thickness with a cornstarch slurry if needed.
How do I fix sauce that's too spicy?
Balance the heat by adding 1 teaspoon sugar or 1 tablespoon milk to mellow the horseradish kick. For a smoother texture, stir in 1 teaspoon of honey or 1 tablespoon of ketchup to dilute the sharpness while keeping the tang. Always taste as you go!
Does this sauce work on other meats besides roast beef?
This sauce elevates grilled chicken, pulled pork, or even steak sandwiches. Its tangy-sweet profile cuts through rich meats beautifully. Try it as a marinade for 1-2 hours before grilling, or drizzle over baked potatoes for a bold twist.
Can I freeze this sauce for later use?
Yes, portion into ice cube trays and freeze. Once solid, transfer cubes to a freezer bag for up to 3 months**. Thaw overnight in the fridge—never at room temperature. The texture may separate slightly after freezing, so whisk vigorously before using. Perfect for meal prep!
