Arby’s Horsey Sauce

To paraphrase the commercial, Arby’s certainly does have the meats. While the fast food chain offers a large and growing menu, there’s no denying the roast beef roots that made Arby’s famous. The delicious, thinly sliced meat is excellent but is made even better with one of Arby’s unique condiments — Horsey Sauce. 

What Makes This Sauce Special?

Arby’s Horsey Sauce is distinctive from the perfect balance of creamy mayonnaise and spicy horseradish. Unlike many copycat recipes that leave you with noticeable bits of horseradish, this version uses creamed horseradish for that signature smooth texture Arby’s fans know and love. With just four simple ingredients, you’ll be amazed at how quickly you can recreate this iconic sauce at home.

Why This Copycat Arby’s Horsey Sauce Recipe is the Best

Those who’ve enjoyed the real thing know Arby’s Horsey Sauce is delightful. But plenty of online recipes for it aren’t, leaving behind noticeable bits of horseradish.

Fortunately, this version solves that problem by opting for creamy horseradish instead, which can be found in the condiment section of your grocery store. Arby’s now sells a bottled version of their Horsey Sauce that you can purchase.

Ingredients You’ll Need

  • Mayonnaise – Creates the creamy, rich base that tempers the horseradish’s heat
  • Creamed horseradish – Provides the signature spicy kick while maintaining a smooth texture
  • Sugar – Balances the heat of the horseradish with a subtle sweetness
  • Salt – Enhances all the flavors and brings them together perfectly
