Arby’s Horsey Sauce Recipe: Tangy and Creamy Copycat Perfection

This creamy, tangy sauce perfectly replicates Arby’s signature Horsey Sauce with just a few simple ingredients. The secret lies in balancing prepared horseradish with mayonnaise and a touch of acidity for that unmistakable zesty kick. I’ve tested multiple ratios to achieve the ideal consistency and flavor profile that matches the fast-food favorite.

What makes this copycat version special is its versatility. Use it as a dipping sauce for fries, a spread for roast beef sandwiches, or a tangy topping for burgers. The recipe comes together in minutes and stores well in the refrigerator for up to two weeks, making it a convenient condiment to keep on hand.

Ingredients for Arbys Horsey Sauce

Eight carefully balanced ingredients recreate Arby’s signature tangy, creamy sauce with professional precision.

The prepared horseradish is non-negotiable for authentic flavor. Bubbies or Gold’s brands deliver the ideal heat level without overpowering bitterness. Optimal quality requires refrigerated horseradish (shelf-stable versions lack freshness). The mayonnaise must be full-fat—Duke’s or Hellmann’s provide the necessary emulsion stability. Vinegar selection impacts acidity balance; distilled white vinegar offers clean sharpness while apple cider adds subtle fruit notes.

For dietary adaptations, vegan mayonnaise (such as Just Mayo or Follow Your Heart) substitutes effectively at a 1:1 ratio. Prepared horseradish contains vinegar, so additional acidity adjustments may be required when substituting. The sugar can be replaced with one-for-one granulated sweeteners like monk fruit or erythritol for sugar-free versions. Garlic powder can be omitted for those sensitive to alliums, though flavor complexity will be slightly diminished.

This emulsion maintains stability for 14 days refrigerated in an airtight container. The high acidity from vinegar and horseradish acts as a natural preservative. For extended storage, portion into ice cube trays and freeze for up to 3 months—thaw individual cubes as needed. Always use a clean utensil to prevent contamination and maintain the 2-week shelf life.

Step-by-Step Instructions for Arby’s Horsey Sauce

This method delivers the signature tangy, creamy balance that defines the classic restaurant version.

Step 1: Prepare the Horseradish Base

Begin by thoroughly draining the 0.33 cup Prepared Horseradish to remove any excess liquid. I recommend pressing it against the side of a fine-mesh strainer with a rubber spatula to extract maximum moisture. This step prevents the final sauce from becoming watery and ensures the proper creamy consistency.

Transfer the drained horseradish to a medium mixing bowl. The prepared horseradish should appear thick and pasty, with no visible standing liquid. This concentration of horseradish flavor forms the foundation of the sauce’s signature tangy kick that balances the richness of the mayonnaise base.

Step 2: Create the Emulsion Foundation

Add the 1 cup High-Quality Mayonnaise to the bowl with the prepared horseradish. Using a silicone spatula, fold the ingredients together with gentle, deliberate strokes until fully incorporated. The mixture will lighten slightly in color as the horseradish distributes evenly throughout the mayonnaise.

At this stage, you’re building the emulsion that gives the sauce its luxurious texture. I prefer full-fat mayonnaise for its superior mouthfeel and stability—lower-fat versions can cause the sauce to separate or develop a thin consistency. The mixture should appear smooth with no visible streaks of white horseradish remaining.

Step 3: Balance the Flavor Profile

Whisk in the 1 tbsp White Vinegar, 1 tsp Granulated Sugar, 0.5 tsp Kosher Salt, and 0.25 tsp Freshly Ground Black Pepper. The vinegar provides essential acidity to cut through the richness, while the sugar balances the horseradish’s natural heat. Continue whisking until the sugar and salt fully dissolve—this typically takes 30-45 seconds of vigorous whisking.

The sauce will begin to develop its characteristic tangy-sweet balance at this point. Taste and adjust the seasoning if needed, though the full flavor won’t develop until after the final ingredients are incorporated and the sauce has time to meld. The texture should remain thick and creamy, coating the back of a spoon completely.

Step 4: Incorporate Finishing Elements

Add the 1 tsp Lemon Juice and 0.25 tsp Garlic Powder to the mixture. The lemon juice brightens the overall flavor profile, while the garlic powder adds subtle depth without overpowering the horseradish’s prominence. Fold these final ingredients in with the same gentle technique used earlier to maintain the sauce’s emulsified structure.

After incorporating, let the sauce rest for 10 minutes at room temperature. This brief resting period allows the flavors to harmonize and the garlic powder to fully hydrate. The finished sauce should have a pale cream color with visible specks of black pepper, and its consistency should be thick enough to cling to sandwiches without dripping.

Step 5: Chill and Serve

Transfer the completed sauce to an airtight container and refrigerate for at least 2 hours before serving. This chilling time is crucial—it allows the flavors to fully develop and the sauce to reach the ideal serving temperature. The cold also slightly thickens the mixture to the perfect dipping consistency.

When ready to use, give the sauce a quick stir to redistribute any separated liquids. The ideal serving temperature is 40-45°F, where the flavors are most vibrant. Store any unused portion in the refrigerator for up to 10 days, though the flavor is best within the first 5 days of preparation. The sauce pairs exceptionally well with roast beef sandwiches, as a dip for fries, or as a tangy complement to fried foods.

Wine and Beer Pairings for This Recipe

Crisp Lagers

The clean, refreshing profile of a classic American lager like Budweiser or Coors Banquet cuts through the creaminess of this sauce beautifully. The light malt sweetness complements the horseradish’s heat while the carbonation cleanses your palate between bites. I always keep a cold one on hand when serving this with spicy fries. 🍺

Wheat Beers

German-style hefeweizens like Paulaner or Weihenstephaner bring citrusy banana-clove notes that harmonize with the sauce’s tangy brightness. The beer’s natural effervescence enhances the creamy texture. I particularly love this pairing with roast beef sandwiches—it’s like a flavor party in your mouth.

Dry Rosé Wines

A chilled Provence rosé with its crisp acidity and red berry notes creates an elegant contrast to the sauce’s richness. Look for bottles with pale salmon color—these typically have the mineral freshness that works best. I discovered this pairing at a summer picnic, and it’s been my go-to for upscale gatherings ever since. 🍷

Sparkling Wines

The bubbles in Prosecco or Cava act like a palate cleanser, making each bite taste as fresh as the first. The slight sweetness in many sparkling wines balances the horseradish’s kick perfectly. I recommend serving this with fried appetizers for a sophisticated happy hour spread.

Amber Ales

Caramel-malt forward ales like Fat Tire or New Belgium Voodoo Ranger add toasty depth that complements the sauce’s creamy base. The moderate bitterness prevents the pairing from becoming too sweet. This is my top choice when serving the sauce with hearty burgers or steak sandwiches.

Sauvignon Blanc

The zesty citrus and grassy notes in New Zealand Sauvignon Blanc mirror the sauce’s tangy profile while adding refreshing acidity. I love how the wine’s grapefruit character enhances the lemon juice in the sauce. This pairing feels particularly refreshing on warm summer evenings. ✨
