Recipe For Arby’s Horsey Sauce: Tangy Ranch and Horseradish Blend

This homemade version captures the signature tangy kick of the original with a perfect balance of creamy ranch and bold horseradish.

I’ve refined this blend to deliver that unmistakable zing without overpowering heat, using simple pantry staples. The key is getting the horseradish-to-ranch ratio just right.

What you’ll end up with is a smooth, versatile sauce that elevates sandwiches, burgers, and even veggie platters. It keeps well in the fridge for up to a week.

Make a double batch—this disappears fast once people try it. Here’s how to mix it up.

Ingredients for Recipe for Arby’s Horsey Sauce

Nine simple ingredients deliver that signature tangy kick with creamy depth.

The mayonnaise and sour cream are non-negotiable for that creamy base—Duke’s or Hellmann’s for mayo, any full-fat sour cream. The horseradish is where the magic happens. Bubbies or Gold’s brands (found at Whole Foods or most grocery stores) have the right punch without being too harsh. If you’re sensitive to heat, start with 2 tablespoons and add more gradually.

No horseradish? Freshly grated horseradish root at half the amount (wear gloves—it’s potent). No sour cream? Full-fat Greek yogurt works in a pinch. Dried dill and parsley are essential for that ranch vibe, but fresh herbs at one-third the amount can sub if that’s what you’ve got. Skip the vinegar if you must, but it brightens everything up.

This keeps beautifully in an airtight container for about 1 week in the fridge. The flavors meld and mellow over time, so making it a day ahead actually improves it. Doubling the batch? Use within 10 days for best quality.

Step-by-Step Instructions for Tangy Ranch and Horseradish Blend

This foolproof mixing method delivers the perfect balance of creamy, tangy, and spicy flavors every time.

Step 1: Combine the Creamy Base

In a medium mixing bowl, add the 1 cup Mayonnaise and 0.5 cup Sour Cream. I always use full-fat versions here—they create that rich, velvety texture that makes this sauce so addictive. Whisk them together vigorously until completely smooth and homogenous.

You’ll notice the mixture becomes slightly paler as air incorporates. This step takes about 30 seconds of steady whisking. The mayonnaise provides the creamy foundation while the sour cream adds that signature tang we’re after.

Step 2: Add the Horseradish and Seasonings

Measure in the 3 tbsp Prepared Horseradish—this is where the signature kick comes from. For a milder version, start with 2 tbsp and add more to taste. Then sprinkle in the 1 tsp Dried Dill Weed, 1 tsp Dried Parsley, 0.5 tsp Garlic Powder, and 0.5 tsp Onion Powder.

The garlic and onion powders might seem subtle, but they add depth to the flavor profile without overpowering. Stir everything together until you see the horseradish fully distributed—no white streaks should remain.

Step 3: Balance with Vinegar and Final Seasoning

Pour in the 1 tbsp White Vinegar and watch how it instantly brightens the mixture. The vinegar cuts through the richness of the mayonnaise and sour cream, creating that perfect tangy balance. Stir for another 20 seconds until fully incorporated.

Now add the 0.25 tsp Salt and 0.25 tsp Black Pepper. I start with these amounts, then taste before adjusting. Remember that the horseradish can vary in saltiness depending on the brand, so go easy with the salt initially.

Step 4: Rest and Develop the Flavors

Cover the bowl with plastic wrap and let it sit in the refrigerator for at least 30 minutes. This resting period allows all the flavors to meld together beautifully. I’ve found that 2 hours gives the best results, but even a short rest makes a noticeable difference.

During this time, the dried herbs rehydrate slightly from the moisture in the mayonnaise and sour cream, distributing their flavors more evenly throughout the sauce. The horseradish’s heat also mellows slightly, creating a more balanced taste.

Give it a final stir before serving. The sauce should be thick but pourable, with a uniform pale color speckled with the herbs. Adjust seasoning if needed, then transfer to an airtight container until ready to use.

Essential Equipment for This Dish

Mixing Bowls

A medium stainless steel mixing bowl is ideal for whisking the base together. I prefer Cuisinox bowls—they’re durable, won’t absorb odors, and the sloped sides make mixing easier. A 2-quart capacity gives enough room to whisk vigorously without splashing. 💡

Whisk Selection

Use a balloon whisk with a comfortable handle for the creamiest results. The OXO Good Grips 11-inch is my go-to—it fits perfectly in medium bowls and the non-slip handle prevents hand fatigue. Avoid flat whisks; they don’t incorporate air as effectively.

Measuring Tools

For precise horseradish measurements, I recommend stainless steel measuring spoons with levelers. The 1 tbsp and tsp sizes get the most use here. Spring-loaded scoops work well for the mayonnaise and sour cream if you’re making frequent batches.

Storage Containers

Transfer the finished sauce to a glass jar with airtight lid for fridge storage. I use Ball Mason jars in 16-ounce size—they’re perfect for single batches and the glass won’t absorb flavors. The wide mouth makes scooping easy. ❄️

Optional Tools

A small silicone spatula helps scrape every last bit from the bowl. The GIR brand spatulas are heat-resistant and flexible. For larger batches, a stand mixer with paddle attachment can handle the whisking, though hand mixing works perfectly fine.
