Sauces & Condiments
This Arby's horseradish sauce recipe delivers that signature creamy, tangy kick you crave in every bite. The secret lies in balancing sharp horseradish with smooth mayo and a touch of sweetness—just like the original. I've perfected this version at home, ensuring it's restaurant-quality without the mystery ingredients.
The sauce is thick enough to cling beautifully to sandwiches or fries while delivering that signature heat. What makes this recipe work is the combination of prepared horseradish (not fresh, which can be too intense) and a precise ratio of mayo, vinegar, and sugar.
The vinegar adds brightness, the sugar rounds out the sharpness, and the mayo creates that signature creamy texture. You'll need just 10 minutes of prep time, and it keeps well in the fridge for up to 2 weeks—perfect for meal prep or entertaining.
The result is a sauce that's creamy yet tangy, with a gradual heat build that starts mild and finishes with a satisfying kick. It's the perfect balance for dipping curly fries, spreading on roast beef sandwiches, or even mixing into deviled eggs.
The texture is smooth and spreadable, with just enough body to hold its shape without being too thick. For extra versatility, adjust the horseradish amount to suit your spice tolerance—start with less if you're sensitive to heat.
Store in an airtight container in the fridge, and give it a stir before each use to maintain consistency. This homemade version tastes fresher and more vibrant than anything you'll find in stores.
Ingredients for arby's horseradish sauce
Eight simple ingredients for that signature Arby's sauce kick—creamy, tangy, and perfectly balanced.
| Ingredient | Amount | Notes |
|---|---|---|
| Prepared Horseradish 🌶️ | ½ cup | Not fresh, for mild heat |
| Mayonnaise 🥛 | 1 cup | Dijon-style preferred for tang |
| White Vinegar 💧 | 1 tbsp | For brightness and balance |
| Granulated Sugar 🍚 | 1 tbsp | Rounds out sharpness |
| Dijon Mustard 🌿 | 1 tsp | Adds depth and tang |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Worcestershire Sauce 🍶 | 1 tsp | For umami depth |
The horseradish is non-negotiable here. Store-bought prepared horseradish (like Gourmet Garden) gives you that signature mild heat without the overwhelming bite of fresh. Trader Joe's and Walmart both carry it, and it's worth grabbing the bigger jar—you'll use it up fast. The mayo should be full-fat for that rich, creamy texture, but if you're watching calories, light mayo works too (just expect slightly less richness). For the vinegar, white is classic, but apple cider adds a nice fruity note if you're feeling adventurous.
No prepared horseradish? Fresh horseradish root at half the amount works, but it's intense—start with less and adjust. Swap the Worcestershire for a dash of soy sauce if you're avoiding it, but you'll lose some depth. The Dijon mustard can be skipped if you're out, but the sugar is important—it balances the heat. For a smoother texture, blend everything for 10 seconds before chilling. If your sauce ends up too thin, add 1 tsp cornstarch mixed with 1 tsp water and stir.
This sauce thickens as it chills, so give it 30 minutes in the fridge before serving. Keeps for 2 weeks in an airtight container, and freezes beautifully for 3 months. I always make a double batch—one for sandwiches, one for fries. The flavor actually improves after a day or two, so don't rush to eat it all at once. For extra heat, add 1/4 tsp cayenne to the mix.

Step-by-step instructions for Arby's horseradish sauce
This creamy, tangy sauce comes together in minutes with simple ingredients you likely already have.
Combine the Creamy Base
In a medium bowl, scoop out the 0.5 cup prepared horseradish and set it aside. This is your heat source—use a rubber spatula to scrape out every last bit from the jar. In the same bowl, add the 1 cup mayonnaise and use the spatula to break up any lumps. The mayonnaise should be completely smooth with no visible streaks.
Here's the thing—this creamy base is what makes the sauce so addictive. The mayonnaise provides that rich, velvety texture that balances the sharp horseradish. Don't skip stirring thoroughly at this stage, or you'll end up with pockets of undissolved horseradish in your final sauce.
Add Sweetness and Tang
Pour in the 1 tablespoon white vinegar and 1 tablespoon granulated sugar. The vinegar brightens the flavors while cutting through the richness, and the sugar rounds out the sharpness of the horseradish. Stir everything together until the sugar dissolves completely—you should see tiny bubbles forming as the mixture comes together.
I like to taste at this point to gauge the balance. It should be noticeably tangy but not overpowering. If you're using Dijon-style mayonnaise, you'll already get some natural tanginess from it. The sugar might seem excessive, but trust me—it prevents the sauce from being too harsh.
Incorporate Depth and Spice
Add the 1 teaspoon Dijon mustard, 0.5 teaspoon salt, 0.25 teaspoon black pepper, and 1 teaspoon Worcestershire sauce. Use your spatula to mix everything together until smooth. The Dijon mustard adds another layer of complexity, while the Worcestershire sauce brings that savory umami depth that makes this sauce so irresistible.
Here's where it gets good—this is when the flavors really start to come together. The Worcestershire sauce might seem like a small amount, but it makes a big difference in that savory profile. Freshly ground black pepper is crucial here—pre-ground pepper loses its punch quickly, so if you have it, grind it right before adding.
Fold in the Horseradish
Now comes the fun part—incorporating the prepared horseradish. Add the 0.5 cup prepared horseradish to the bowl and gently fold it in with your spatula. Be careful not to overmix—you want to distribute the horseradish evenly without creating too many air bubbles. The sauce should have a consistent color throughout with no visible streaks of horseradish.
At this stage, you might think it's too strong, but remember—this is the signature Arby's flavor profile. The creamy base will mellow out the sharpness. Taste a small spoonful and adjust if needed. If it's too spicy, add a tiny bit more mayonnaise to balance it out. If it needs more kick, add a pinch more salt or a dash of vinegar.
Rest and Serve
Let the sauce sit at room temperature for 10-15 minutes before serving. This resting time allows all the flavors to meld together perfectly. The sauce will thicken slightly as it comes to room temperature, which is actually ideal for dipping or spreading.
This sauce is incredibly versatile—perfect for dipping fries, spreading on sandwiches, or even mixing into deviled eggs. The key to its success is the balance between the creamy mayonnaise base and the sharp horseradish. Store any leftovers in an airtight container in the refrigerator for up to 5 days, though I doubt it'll last that long!
Pro Tips For Making Arby'S Horseradish Sauce
- STIR GENTLY: Mix the sauce in stages—first fold in the mayo and mustard until smooth, then slowly drizzle in the horseradish while stirring in one direction. Horseradish is aggressive; rushing it makes the sauce separate like a stubborn temper tantrum.
- USE COLD INGREDIENTS: Keep your mayo, horseradish, and Dijon chilled until the very last step. Warmth turns this sauce into a greasy mess faster than you can say "roast beef sandwich." Pop everything back in the fridge for 10 minutes if your kitchen’s warmer than a summer day.
- MEASURE THE VINEGAR: The white vinegar isn’t just there to cut flavors—it’s the glue. Too much and you’ll taste the pickling jar; too little and the horseradish will overpower like an overzealous party guest. Stick to the 1 tablespoon mark unless you’re aiming for a condiment that doubles as a sinus cleanser.
- SWEETEN GRADUALLY: Add the sugar one teaspoon at a time while tasting. The mayo and Dijon already have sweetness hiding in them, and you don’t want to end up with a dessert sauce. Think "balancing act," not "dump-and-pray."
Pro cooking tips for this dish
Creamy Texture Secrets
The magic of this sauce lies in the mayonnaise-to-horseradish ratio—never skip using full-fat mayo for that signature Arby's richness. I recommend Dijon-style mayo like Hellmann's or Best Foods for extra tang. If you're worried about consistency, blend everything for 10 seconds after mixing to eliminate any lumps.
For a smoother finish, chill the sauce for 30 minutes before serving—this lets the flavors meld and the texture thicken just right. 🥛
Heat Control Tips
Prepared horseradish is milder than fresh, but if you prefer extra kick, add ¼ tsp cayenne pepper or ½ tsp hot sauce (like Frank's RedHot). For a gradual heat build, start with ¼ cup horseradish and adjust to taste.
If it's too spicy, balance it with 1 tsp more sugar or 1 tsp extra mayo. Pro tip: Taste as you go—this sauce should start mild and finish with a satisfying burn.
Flavor Layering Tricks
The Worcestershire sauce is non-negotiable for that deep umami punch. If you're avoiding it, swap in ½ tsp soy sauce or 1 tsp fish sauce for a similar savory boost. Freshly ground black pepper makes a huge difference—pre-ground pepper loses its punch quickly.
For extra brightness, replace white vinegar with apple cider vinegar (just reduce to ½ tbsp to avoid overpowering). The sugar isn't just for sweetness—it cuts through the sharpness for a balanced bite.
Storage Hacks
This sauce thickens as it chills, so store it in an airtight container in the fridge for up to 2 weeks. For longer storage, freeze in ice cube trays—thaw overnight in the fridge and stir before using.
If your sauce separates, whisk in 1 tsp water to restore consistency. I always double the batch—one for sandwiches, one for fries. The flavor actually improves after 24 hours, so make it a day ahead for the best results. ❄️
Versatile Uses
While this sauce is perfect for dipping curly fries or spreading on roast beef sandwiches, don't limit it to those uses. Mix 1 tbsp into deviled eggs for a spicy kick, or drizzle over baked potatoes with sour cream.
For a creamy dip, serve it with veggie sticks or pretzel bites. The key is its versatility—it works as a condiment, a dip, or even a marinade for grilled meats. Trust me, you'll find a million ways to use it up!
Troubleshooting Guide
If your sauce is too thin, stir in 1 tsp cornstarch mixed with 1 tsp water and let it thicken for 5 minutes. For too thick sauce, add 1 tsp water or vinegar and whisk until smooth.
If it tastes too sharp, balance it with ½ tsp more sugar or 1 tsp honey. For not enough heat, add ¼ tsp extra horseradish or a pinch of cayenne. Always taste as you go—this sauce is all about balance between creamy, tangy, and spicy. 💡

Frequently asked questions
Can I use fresh horseradish instead of prepared?
Fresh horseradish is much stronger and can overpower the sauce. Use only ¼ cup fresh horseradish (grated) for every ½ cup prepared horseradish in the recipe. Start with less and adjust to taste—fresh root has a raw, intense heat that prepared horseradish mellows out.
How do I make this sauce less spicy?
Add 1 tsp more sugar or 1 tsp extra mayonnaise to balance the heat. For a milder version, reduce the prepared horseradish to ¼ cup and replace the difference with mayo. The sugar helps round out the sharpness while the mayo adds creaminess to dilute the spice naturally.
Can I make this sauce dairy-free?
Yes! Replace the mayonnaise with vegan mayo (like Hellmann's Vegan or Just Mayo) and use dairy-free Worcestershire sauce. The texture will be slightly lighter, but the tangy-spicy balance remains. For extra richness, stir in 1 tbsp cashew cream at the end.
Why did my sauce separate?
Separation happens when ingredients aren't fully emulsified. Blend the sauce for 10-15 seconds after mixing, or whisk in 1 tsp water to restore consistency. For prevention, chill the sauce for 30 minutes before serving—this helps the ingredients bind properly. Store in an airtight container to maintain texture.
How long does this sauce keep?
This sauce stays fresh for 2 weeks in the fridge when stored in an airtight container. For longer storage, freeze in ice cube trays—thaw overnight in the fridge and stir before using. The flavor actually improves after 24 hours, so making it ahead is ideal for meal prep.
