Arby's Horseradish Sauce Recipe: Creamy Heat With A Kick

This Arby's horseradish sauce recipe delivers that signature creamy heat you crave, with a perfect balance of tangy kick and smooth texture. 🔥 The secret lies in blending fresh horseradish with high-quality mayo, a touch of vinegar, and just the right amount of seasoning to mimic that restaurant-quality zing.

I've perfected this version after testing countless batches, ensuring it's smoother than store-bought but just as bold.

The magic happens when you combine prepared horseradish with mayonnaise and apple cider vinegar, then let the flavors meld for at least 30 minutes before serving. This waiting period allows the horseradish's sharpness to mellow slightly while maintaining that signature creamy consistency.

The sauce keeps beautifully in the fridge for up to two weeks, making it perfect for meal prep or hosting.

What makes this recipe stand out is how closely it replicates Arby's signature sauce—tangy enough to cut through rich meats but smooth enough to spread effortlessly. The vinegar adds brightness, while a pinch of salt and black pepper rounds out the flavor.

This isn't just any horseradish sauce; it's the one that'll have your guests asking for the recipe.

Whether you're dipping fries, topping burgers, or serving with roast beef, this sauce brings that familiar Arby's flavor to your table. The best part? You'll never need to buy it again once you taste how much better homemade can be. Let's get started on making this crowd-pleaser!

Ingredients for arby's horseradish sauce

Just eight ingredients transform into that iconic Arby's sauce you love—creamy, tangy, and packed with heat!

The horseradish is where the magic happens. Freshly grated gives the best texture and flavor, but prepared horseradish works in a pinch—just make sure it's not too watery. Trader Joe's and Whole Foods carry excellent prepared horseradish, or grab a small jar from the condiment aisle. For mayo, Hellmann's or Duke's are my go-tos—their smooth texture keeps the sauce velvety. The apple cider vinegar adds that signature tang, so don't skip it. I always grab the Bragg brand—it's reliable and affordable.

No fresh horseradish? Prepared horseradish from a jar works, but strain out any excess liquid to keep it thick. Short on mayo? Greek yogurt mixed with a bit of olive oil gives a tangier, lighter version. The Dijon mustard is key—it adds complexity that regular mustard can't match. Want it spicier? Add a pinch more horseradish or a dash of cayenne. For a sweeter touch (like the original), adjust the sugar to taste. The lemon juice is non-negotiable—it brightens everything and cuts through the richness.

This sauce gets better with time—let it sit for at least 30 minutes before serving so flavors meld. Store it in an airtight container in the fridge for up to 2 weeks. I always make extra because it disappears fast—perfect for meal prep! If it thickens too much, stir in a splash of water or milk. For serving, I like to pipe it into a bowl for that restaurant-style presentation.

Step-by-step instructions for creamy heat with a kick

This tangy, spicy sauce comes together in minutes with just a few simple steps.

In a medium bowl, combine the 1 cup mayonnaise with the 0.5 cup prepared horseradish. Use a whisk or silicone spatula to mix until smooth and fully incorporated—this ensures no harsh horseradish bits remain. I like to press the mixture through a fine-mesh sieve if using freshly grated horseradish to eliminate any texture.

Here's the thing—horseradish can be aggressive, so take it slow. Add the 1 tbsp apple cider vinegar and 1 tbsp granulated sugar next, whisking continuously. The vinegar brightens the flavors while the sugar just slightly balances the heat. You'll notice the mixture thicken slightly as the sugar dissolves completely.

Stir in the 1 tsp Dijon mustard—this adds that signature tangy depth that makes this sauce so addictive. The Dijon blends beautifully with the horseradish while adding a subtle complexity. Now for the seasonings: sprinkle in the 0.25 tsp kosher salt and 0.25 tsp freshly ground black pepper, mixing thoroughly after each addition.

I always taste at this stage to check the balance. You want the heat to be noticeable but not overwhelming—this is where the sugar and vinegar work their magic. If it's too sharp, add a pinch more sugar; if it's too mild, a tiny splash of vinegar helps. Remember, you can always adjust later, but it's easier to fix under-seasoned than over-seasoned.

Give the mixture one final stir before adding the 1 tsp fresh lemon juice. This is the secret ingredient that lifts all the flavors—giving it that fresh, vibrant quality that makes this sauce so irresistible. The lemon juice should be freshly squeezed for maximum brightness and acidity.

Mix everything together until completely smooth. The sauce should have a creamy, slightly thick consistency with a vibrant yellow-orange hue from the horseradish. If it's too thick, add 1-2 teaspoons of water to reach your desired pouring consistency. Taste again and make any final adjustments—this is your chance to dial in the perfect heat-to-creamy ratio.

Cover the bowl with plastic wrap and refrigerate for at least 30 minutes (I prefer 1 hour for best results). This chilling time allows all the flavors to meld together beautifully. The horseradish's heat will mellow slightly while the lemon and vinegar brighten the overall profile.

Don't skip this step—it makes a world of difference. When you're ready to serve, give it one final taste. The sauce should be creamy, tangy, and just spicy enough to make your eyes water slightly. Serve immediately with your favorite sandwiches, burgers, or as a dip for crispy fries—this is where the magic really happens!

Flavor customization for this recipe

Spice Level Control

Adjust the heat to your taste by modifying the horseradish amount. For a milder kick, reduce to ¼ cup prepared horseradish and add ½ tsp honey to balance. For extra spice, increase to ⅔ cup and add ¼ tsp cayenne pepper.

I often make two batches—one mild for kids and one fiery for adults. Always taste before serving! 🌶️

Tangy Variations

Swap apple cider vinegar for white wine vinegar (for a more refined flavor) or rice vinegar (for a subtle sweetness). For a garlicky twist, add ½ tsp minced garlic or 1 tsp garlic powder.

I love using Bragg apple cider vinegar—it’s consistent and adds a nice depth without overpowering.

Dairy-Free Adaptations

Replace mayo with Greek yogurt (use ¾ cup plain, full-fat) mixed with 1 tbsp olive oil for creaminess. Add ½ tsp xanthan gum to thicken if needed. For extra tang, stir in 1 tsp lemon juice. This version works perfectly with vegan sandwiches or roasted veggies. 🥛

Sweet & Smoky Twist

Add ½ tsp smoked paprika and ½ tsp brown sugar for a BBQ-inspired horseradish sauce. This pairs amazingly with pulled pork or grilled chicken. For a caramelized touch, lightly toast the sugar in a dry pan before mixing it in. The smokiness complements the horseradish beautifully.

Herb-Infused Freshness

Stir in 1 tbsp finely chopped fresh dill or chives for a bright, herbaceous note. For a citrus burst, add ½ tsp grated lemon zest along with the juice.

I often use dill because it pairs perfectly with the tangy horseradish. Fresh herbs elevate the sauce from good to restaurant-quality! 🌿

Storage & Flavor Boost

For longer shelf life, store in an airtight glass jar in the fridge for up to 3 weeks. To revive flavors, add 1 tsp lemon juice or a pinch of salt before serving.

If the sauce separates, whisk in 1 tsp water or milk to restore creaminess. Freeze in ice cube trays for single-serving portions—just thaw overnight in the fridge. ✨
