Ingredients for arby's roast beef sandwich sauce
Five simple ingredients unlock the Horsey sauce magicâcreamy, tangy, and addictive.
| Ingredient | Amount | Notes |
|---|---|---|
| Mayonnaise đ„« | Ÿ cup | High-quality, full-fat preferred |
| Prepared Horseradish đ¶ïž | ÂŒ cup | Creole-style for extra kick |
| White Vinegar đ§ | 2 tbsp | Distilled or white preferred |
| Granulated Sugar đ | 1 tbsp | White or raw preferred |
| Kosher Salt đ§ | Âœ tsp | Diamond Crystal preferred |
| Black Pepper đ¶ïž | ÂŒ tsp | Freshly ground for best flavor |
| Worcestershire Sauce đ¶ | 1 tbsp | Vegetarian version if needed |
The mayo is the base, so Duke's or Hellmann's are my go-tosâthey've got that perfect balance of richness without overpowering. Horseradish is non-negotiable for that signature bite; Gourmet Garden Creole-style adds depth while keeping it smooth. I grab mine at Kroger or Walmartâjust make sure it's not the pre-grated kind, which can get gritty. For the vinegar, Heinz or White House** brands work perfectly, but avoid anything with added flavors. The sugar and salt are just to round out the flavors, so don't stress about fancy brands here.
No horseradish? Substitute 1 tbsp extra mustardâit won't be identical, but it'll get you close. Short on mayo? Greek yogurt thinned with a splash of milk works in a pinch, though the texture will be slightly different. The Worcestershire sauce adds umami depth, so if you're avoiding it, a dash of soy sauce can help. For a smoother texture, strain the sauce through a fine-mesh sieve before usingâespecially if your horseradish is chunky. The key is letting it sit for at least 30 minutes before using, which lets the flavors meld perfectly.
This sauce keeps beautifully in the fridge for up to 1 week in an airtight container. For longer storage, divide it into ice cube trays and freezeâjust thaw overnight in the fridge before using. The flavors actually improve after a day or two, so make a batch and enjoy it all week. If it thickens up, just stir in a splash of water or milk to loosen it. And trust me, you'll want to make extraâit disappears fast!

Step-by-step instructions for Arby's roast beef sandwich sauce
This tangy, creamy sauce brings that iconic Arby's flavor to your kitchenâeasy, fast, and packed with punch.
đšâđł Step 1: Whisk Together the Creamy Base
In a medium bowl, combine the 0.75 cup mayonnaise and 0.25 cup prepared horseradish. Use a whisk to blend them thoroughly for about 30 seconds until smooth and fully incorporated. The horseradish will give that signature kick, so don't skip this stepâit's what makes this sauce uniquely "Horsey."
Here's the thingâif you're using Creole-style horseradish, you'll notice a deeper, more complex flavor than regular prepared horseradish. This is the secret to replicating that authentic Arby's taste. Taste the mixture now; it should be creamy with a sharp, spicy note. If it's too intense, you can adjust later, but we're aiming for bold flavor here.
đ„ Step 2: Add the Acidic and Sweet Components
To the mayonnaise-horseradish mixture, add the 2 tablespoons white vinegar, 1 tablespoon granulated sugar, 0.5 teaspoon kosher salt, and 0.25 teaspoon black pepper. Whisk everything together for another 30 seconds until the sugar dissolves completely and the salt and pepper are evenly distributed.
The vinegar cuts through the richness of the mayonnaise, balancing the sharpness of the horseradish. The sugar might seem odd, but it rounds out the acidity and creates that perfect harmony of flavors. You'll see the mixture lighten slightly as the sugar integratesâthis is your cue that it's working. Taste again; the sauce should now have a bright, tangy edge with a touch of sweetness.
đł Step 3: Incorporate the Umami Depth
Finally, stir in the 1 tablespoon Worcestershire sauce using a spatula or wooden spoon. This step adds a savory, umami depth that ties all the flavors together. Mix gently to avoid creating air bubbles, and let the sauce sit for 2 minutes to allow the Worcestershire to meld with the other ingredients.
Real talk: the Worcestershire sauce is non-negotiable for that authentic Arby's taste. It brings a meaty, slightly funky note that elevates the sauce from good to "I need this on everything." If you're using a vegetarian version, the flavor will still be there, but it might be slightly milder. Give it a taste nowâthe sauce should be creamy, tangy, slightly sweet, and just a touch spicy with a deep umami backbone.
â° Step 4: Rest and Adjust for Perfection
Let the sauce rest at room temperature for 10 minutes. This resting period allows all the flavors to fully marry and the sharpness of the horseradish to mellow slightly. After resting, give it one final taste and adjust the seasoning if needed. You might want to add a pinch more salt, a splash of vinegar for extra tang, or even a tiny bit more sugar to balance the flavors.
Your homemade Arby's sauce is now ready to use! It's best served immediately on roast beef sandwiches, but it will keep in the refrigerator for up to 5 days in an airtight container. The flavors will continue to meld over time, so if you can wait, the sauce will only get better. Trust meâonce you taste this on your homemade roast beef sandwich, you'll never buy it at the restaurant again.
Pro Tips For Making Arby'S Roast Beef Sandwich Sauce
- Whisk Slowly First: Drizzle the mayonnaise in while stirring constantlyâthis prevents lumps from forming when you add the horseradish later. I learned this the hard way after ending up with a grainy, sad sauce that looked like it lost a fight with a blender. ---
- Use Fresh Horseradish: That jarred horseradish loses its kick over time. If yours tastes mild, grate a fresh rootâitâs sharper, brighter, and actually makes the sauce taste like Arbyâs instead of a generic horseradish mayo. (Yes, even if youâre impatient like me.) ---
- Balance the Vinegar: Start with just Âœ teaspoon of vinegar, taste, then add more. Too much turns the sauce into a sad, tangy mess, but the right amount cuts the richness and makes the horseradish pop. I was skeptical until I tried itânow I double-check every time. ---
- Salt in Stages: Taste after mixing everything, then salt in tiny increments. The sugar and vinegar throw off your salt perception, and youâll end up overdoing it if you eyeball it. Trust me, your sandwich will thank you.

Try it on classic deli meats like pastrami or corned beef for a flavor upgrade. The sauce also works surprisingly well on pulled pork sandwichesâthe sweetness of the pork pairs beautifully with the tangy kick. For a quick lunch, assemble a roast beef wrap with tortillas, spinach, and this sauce for a portable, restaurant-quality meal.

Frequently asked questions
Why does Arby's sauce have horseradish?
The horseradish is the secret weapon! It gives the sauce that signature sharp, spicy kick that cuts through the richness of roast beef. The Creole-style variety adds depth without overpowering, creating that perfect balance of tangy, creamy, and slightly spicy flavors that make the sauce so addictive. Without it, you'd miss that iconic Arby's taste.
Can I make this sauce without Worcestershire sauce?
You can substitute it, but you'll lose that deep umami flavor. Try 1 teaspoon soy sauce or 1/2 teaspoon fish sauce for a similar savory note. If avoiding both, simply omit itâthe sauce will still be tangy and creamy, just slightly less complex. The Worcestershire is what gives it that "restaurant-quality" depth.
How do I fix it if my sauce is too spicy?
Add 1/2 teaspoon more sugar or 1 teaspoon honey to balance the heat. You can also stir in 1/2 teaspoon Dijon mustard, which adds creaminess and mellows the horseradish's sharpness. If it's still too intense, thin it slightly with 1 teaspoon milk or water to dilute the flavor.
What's the best way to store leftover sauce?
Transfer to an airtight container and refrigerate for up to 5 days. For longer storage, freeze in ice cube traysâjust thaw overnight in the fridge. The flavors actually improve after 24 hours as everything melds together. If it thickens, stir in a splash of water or milk to restore creaminess.
Can I use this sauce on other meats besides roast beef?
It works perfectly on turkey, chicken, pastrami, or even pulled pork. The tangy-sweet balance complements rich meats beautifully. For vegetarian options, try it on grilled portobello mushrooms or marinated tofu. Just be mindful that some meats (like chicken) may need slightly less sauce to avoid overpowering the flavor.
