Arby’s Horsey Sauce Recipe


You’d be forgiven for thinking that Arby’s is a play on ‘R-B’ for roast beef. It in fact stands for the founders; the Raffel Brothers.

In this recipe we are going to give your our very own, homemade Arby’s Horsey sauce recipe. We’ll talk about all the good stuff with regards to how to make it and offer you some tips and tricks to really make it shine.

How To Make Arby’s Horsey Sauce

As you’ll probably be aware Arby’s specializes in meats and particular placing those meats on a sandwich. Few things go better with roast beef than horseradish sauce. In case you were wondering the name from Arby’s horsey sauce comes directly from its main ingredient, horseradish.

Horseradish isn’t often used in many other dishes. The reason for this is that it is a fairly strong flavor. It’s a little bit earthy, a little bit peppery and to be frank, quite hot.

The best bit about our Arby’s horsey sauce recipe is that no real expertise, or fancy equipment is required. If you have a bowl, a spoon and some idea of measurements you should be ‘hot to trot’ (that’s a horse joke in case you were wondering).

Depending on the approach you take, you might need a grater and a food processor too, but we are going to talk about these both in our tips and tricks section. Speaking of which, let’s take a look: –

  • 8 oz 8 mayonnaise (either full or low fat is fine)

  • Two teaspoons Two of sugar

  • 2 oz 2 horseradish sauce or 4 teaspoons

  • A generous pinch of salt.


  • Take a small bowl and add your mayonnaise. Add the sugar and, using a whisk, mix until the sugar has dissolved.
  • Add the horseradish and continue whisking until thoroughly combined.
  • Add the salt and taste. If the sauce needs a little extra feel free to add some more, but don’t overdo it.
  • (Optional) For really smooth sauce and as we discussed blitz in a food processor until silky smooth.
  • Chill for at least half an hour (the longer the better).
  • Serve with burgers, meat or even fish in thick spoonful’s.
  • Serve and enjoy.


  • This recipe calls for mayonnaise. Now there are two ways to do this. The easy way, and the super classy, impress everybody way. The easy way is to use shop bought mayonnaise. However, if you want to take your Arby’s Horsey sauce recipe to the next level you can consider using homemade mayonnaise. This way you can get the flavor and texture exactly to your liking.
  • Arby’s Horsey sauce is super creamy. If you want a slightly milder or creamier sauce then the addition of a tablespoon of cream will loosen its consistency and should provide it with a super silky edge.

Tips & Tricks

  • Let’s talk about horseradish. It isn’t always the easiest thing to get hold of. If you haven’t managed to pick a jar up then don’t panic as we’ve got a couple of solutions. Now, granted the recipe won’t taste exactly like authentic Arby’s horsey sauce, but it still should come pretty close. Do you know what other foods are related to horseradish? Well, another great accompaniment to roast beef is… English mustard. The reason it works so well is that it tastes very similar to horseradish, so if you have any lying around feel free to give it a try instead. There’s another alternative which tastes practically identical to horseradish. If you are in a fix, give Wasabi a try. Ok your sauce might have a green tinge, but it should taste similar.
  • Have you ever eaten left over food from the night before and found that it tastes even better? As with most sauces, we recommend leaving this sauce to chill and rest for at least a half hour before serving. It’s not a deal breaker if you are pushed for time, but by leaving the sauce you allow the ingredients to meld and fuse together. Don’t worry if you just can’t wait though.
  • Arby’s horsey sauce is super smooth. The main flavor is achieved by using horseradish sauce. Depending on which brand you buy, you may find it has ‘bits’ in it. If you choose you can go a little rustic and use it ‘as is’. This won’t affect the flavor of your sauce but if you are really looking for an authentic Arby’s horsey sauce, we recommend going down the smooth route. If you can only find sauce with pieces of horseradish, but you want smooth, just give your sauce a blitz in a food processor after you have made it.
  • If you have been fortunate enough to find fresh horseradish you are in for a taste sensation. Just use the fine side of a box grater to make a horseradish pulp. Use about 4 teaspoons in place of the horseradish sauce in this recipe.

How Long Can I Store This?

It’s one thing making up a delicious sauce but another not knowing how long it will last. This recipe will keep in the refrigerator for up to 3 days after making. It really does taste nicer the longer you leave it. Just leave in a bowl covered or in a lidded jar.


When a restaurant such as Arby’s makes a sauce to accompany its meats, you know it is going to work perfectly. The fact that so many people love it is proof.
