Ingredients for arby's roast beef sandwich sauce
Nine simple ingredients blend into Arby's iconic tangy, creamy roast beef sauce.
| Ingredient | Amount | Notes |
|---|---|---|
| Mayonnaise 🥫 | 1 cup | Store-bought or homemade preferred |
| Prepared Horseradish 🌶️ | ½ cup | Creole or classic variety |
| Worcestershire Sauce 🍶 | 2 tbsp | High-quality brand recommended |
| Garlic Powder 🧄 | 1 tbsp | Freshly ground preferred |
| Dried Onion Flakes 🧅 | 1 tsp | For subtle sweetness |
| White Vinegar 💧 | 1 tbsp | Distilled preferred |
| Granulated Sugar 🍚 | ½ tsp | Balances tanginess |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground for best flavor |
The horseradish is non-negotiable—Creole-style has more depth than classic, but either works. Grocery store brands are fine, but Gourmet Garden or Liberty deliver that signature kick. Worcestershire sauce should be full-bodied, not vinegar-forward—Lea & Perrins is the gold standard. Garlic powder loses potency fast, so buy small amounts or store it in the freezer to preserve freshness. The white vinegar adds brightness, but apple cider vinegar works too if you prefer a fruity note.
No horseradish? Substitute 1 tbsp hot sauce plus 1 tsp lemon juice—it won't be identical, but close. Worcestershire sauce hard to find? Fish sauce plus a pinch of sugar mimics the umami depth (though it's not vegetarian). Short on garlic powder? Add 1 extra clove of minced fresh garlic for intensity. The sugar balances the tang—brown sugar adds molasses notes if you want extra complexity. Salt and pepper are flexible, but black pepper is key for that Arby's signature bite.
This sauce keeps for 2 weeks in an airtight container in the fridge—perfect for batch prep. For longer storage, freeze in ice cube trays and transfer to a bag. Thaw overnight in the fridge. The texture stays smooth if you whisk it before using. Double the batch—you'll want it for everything from roast beef sandwiches to fries.

Step-by-step instructions for Arby's-style roast beef sauce
This sauce captures the iconic balance of creamy richness and bold, tangy kick that makes Arby's sandwiches legendary.
Whisk Together the Base Ingredients
In a medium bowl, combine the 1 cup mayonnaise and 0.5 cup prepared horseradish. Use a whisk to blend them thoroughly for about 30 seconds—this ensures the horseradish is evenly distributed without creating lumps. The mixture will have a thick, creamy texture with a noticeable kick from the horseradish.
Next, add the 2 tablespoons Worcestershire sauce and 1 tablespoon garlic powder. Stir well to incorporate these flavors completely. The Worcestershire sauce adds a deep, umami richness, while the garlic powder introduces a subtle, aromatic depth. If you're using freshly ground garlic powder, you'll notice a more pronounced flavor, but don't overdo it—this sauce relies on balance.
Add the Acidic and Sweet Components
Pour in the 1 tablespoon white vinegar and 0.5 teaspoon granulated sugar. The vinegar brightens the flavors and cuts through the richness of the mayonnaise, while the sugar just slightly balances the tang. Mix these ingredients in until fully combined. You'll notice the sauce becoming slightly thinner as the vinegar incorporates, but it should still hold its shape.
At this stage, taste the mixture. It should have a creamy, slightly spicy base with a hint of tang and sweetness. If it tastes too sharp, add a pinch more sugar. If it's too mild, a splash of vinegar can help. This is your chance to adjust the balance before adding the final seasonings.
Season and Finish the Sauce
Add the 0.5 teaspoon salt and 0.25 teaspoon black pepper to the bowl. Stir these in until fully dissolved. The salt enhances all the flavors, while the pepper adds a subtle warmth. At this point, give the sauce one final taste. It should be creamy, tangy, and just spicy enough to complement roast beef without overpowering it.
Transfer the sauce to an airtight container and refrigerate for at least 30 minutes before serving. This resting time allows the flavors to meld together perfectly. The sauce will keep in the refrigerator for up to 1 week, making it ideal for batch prep. When ready to use, give it a quick stir to ensure all the flavors are evenly distributed.
Pro Tips For Making Arby'S Roast Beef Sandwich Sauce
- STIR GENTLY, THEN REST: Mix the sauce with a rubber spatula—just until combined—then let it sit for 10 minutes. The flavors meld better when you don’t overwork it, and the horseradish’s kick softens just enough to avoid an immediate burn.
- USE FRESH HORSE RADISH: That jarred horseradish loses potency fast. If yours tastes weak, add a pinch of extra garlic powder or a dash of lemon juice to cut through the flatness. (I learned this the hard way after using a 2-year-old bottle.)
- MEASURE WORCESTERSAUCE LAST: Add Worcestershire sauce in two stages: half first, taste, then adjust. Too much upfront can make the sauce taste sharp and unbalanced—especially if your mayo is thick or your horseradish is strong.
- SWAP ONION FLAKES FOR POWDER: Dried onion flakes can clump and look unappetizing. Crush them lightly in a mortar or between your palms before adding, or swap for onion powder for a smoother texture. (Yes, it’s a small detail, but it matters when you’re slathering it on bread.)
Regional styles of this dish
Midwest Classic
In the heartland of America, where Arby's first opened in 1964, this sauce became a regional staple. The original recipe relied on locally available ingredients like mayonnaise from Hellmann's (still popular in Midwest grocery stores) and Liberty brand horseradish, which had a milder kick than Creole varieties. The sauce's simplicity made it perfect for quick-service restaurants—no fancy equipment needed, just a whisk and a bowl. 🌟
The Midwest version often includes a pinch of onion powder instead of flakes for a smoother texture, and some regional recipes call for a splash of pickle juice (about 1 teaspoon) to add a subtle tang. This adjustment became popular in states like Ohio and Indiana, where pickles were a common pantry staple. The sauce's creamy consistency also made it ideal for pairing with Midwest-style fries—a combo that became a menu favorite.
Southern Tangy Twist
Down South, the sauce gets a spicier kick with hot sauce substitutions like Crystal or Tabasco (about 1 teaspoon) replacing some of the Worcestershire. Southern cooks also often add smoked paprika (about ¼ teaspoon) to echo the barbecue flavors common in the region. The result is a sauce with a bold, slightly smoky profile that pairs perfectly with slow-cooked roast beef—a nod to Southern barbecue traditions. 🔥
In states like Georgia and Alabama, some versions even include a dash of cayenne pepper (about ⅛ teaspoon) for extra heat, while others swap the white vinegar for apple cider vinegar to add a fruity depth. The sauce’s tanginess also makes it a great dip for Southern-style collard greens or cornbread, turning it into a versatile condiment beyond just sandwiches.
Northeast Creamy Version
Up North, the sauce leans even creamier, often using homemade mayonnaise (like a Dijon mustard-infused version) for a richer texture. The Northeast version also tends to include extra garlic powder (about ½ teaspoon) to match the region’s love of bold, garlicky flavors. Some cooks in New York and Massachusetts even add a pinch of celery salt (about ⅛ teaspoon) for a savory depth that complements the roast beef. ⚡
In colder climates, the sauce is also popular as a dipping sauce for loaded baked potatoes or as a spread for pretzels during winter gatherings. The Northeast’s love for hearty, comforting foods makes this sauce a year-round favorite, not just a sandwich condiment. The extra creaminess also helps balance out the spicier horseradish, making it more approachable for those who prefer milder flavors.
West Coast Smoky Adaptation
Out West, the sauce gets a smoky twist with additions like liquid smoke (about ½ teaspoon) or smoked salt (about ¼ teaspoon). This adaptation reflects the region’s love of grilled and smoked meats, making the sauce a perfect match for California-style roast beef sandwiches or smoked brisket platters. The smoky notes also pair beautifully with West Coast avocado toast or grilled veggie wraps. 🌶️
In states like California and Washington, some versions even include a splash of balsamic vinegar (about 1 teaspoon) to add a touch of sweetness and complexity. The sauce’s versatility makes it a hit at food trucks and farmers' markets, where it’s often served as a dipping sauce for fries or loaded nachos. The West Coast adaptation proves that this sauce isn’t just for sandwiches—it’s a flavor powerhouse for any meal.

What if my sauce tastes too spicy?
Add 1 teaspoon more mayonnaise or ½ teaspoon sugar to balance the heat. You can also thin it slightly with ½ teaspoon water or milk to mellow the flavors. If you prefer a milder sauce from the start, reduce the horseradish to ¼ cup and add ½ teaspoon extra garlic powder for depth instead.
