Copycat Arby's Horsey Sauce Recipe

There's a lot to love about Arby's, from the Creamy Mediterranean Chicken Wrap to a Roast Turkey Slider to Mozzarella Sticks. But let's be honest: At the end of the day, most folks come to Arby's for two things, and those are the Classic Roast Beef Sandwich and the Arby's Horsey Sauce, a delectable condiment/dip that has just the right amount of zest and kick to make just about anything you eat a genuine treat. And yes, especially the aforementioned Classic Roast Beef Sandwich.

Chef and recipe developer Melissa Johnson says that this sauce is great with a meat-centric sandwich, saying that it "goes great with beef but would be perfect with prime rib also. However, you should feel free to branch out and pair this sauce with whatever you like. Try it on a veggie burger, with chicken (anywhere you like a blue cheese sauce, this sauce will work well), with mozzarella sticks, or something else entirely. As long as you like life a bit on the spicy side, you'll love this dip, which is tasty and easy to prepare.

The ingredients for this recipe could not be much simpler. All you need to prepare this tasty dip/spread/dressing is a cup of mayonnaise, a quarter of a cup of creamed horseradish, a tablespoon of sugar, and just a third of a teaspoon of salt. You can handle gathering all that, right? Johnson knows you can, saying, "No mistakes to watch for, besides maybe going too heavy on the horseradish. I think this recipe has the perfect amount of spicy kick, but there's the option of using less horseradish for people who don't like it as 'horseradishy.'"

And hey, don't worry: You can go the other way too, adding even more horseradish if you love that unique spice flavor.

Worried that we were overselling how easy things are here? Well, worry not. In fact, let's see if we can sum up the prep for this recipe in just two words:

Combine everything.

Yep, that does it. Simply place all of the ingredients — mayo, then horseradish, then sugar, then salt — into a bowl and stir them together well until they fully blend. And that's it. If you have the time, chill and rest the sauce in the fridge for an hour before serving, but you can indeed enjoy it immediately. And it will keep in the fridge in an airtight container for an entire week.

Chances are good you have never seen horseradish in any state but a sauce, so just what is at the root of this uniquely spicy stuff, anyway? Why, a root, as it happens. According to Healthline, horseradish is "a root vegetable known for its pungent taste and odor." Usually served after being finely grated and blended with vinegar and salt, horseradish can accentuate the flavors of myriad foods.

While usually eaten in small portions and thus not a notable source of healthy vitamins of minerals, horseradish is nonetheless a healthful food. It has antioxidants and antibacterial properties, and it contains some calcium, magnesium, and potassium.
