Arby's Horsey Sauce Recipe
My husband loves Arby's Roast Beef sandwiches. They are one of his favorite fast-food lunches to grab on the go. Being home this past year he started missing many of his favorite restaurant meals.
I have been working on making as many copycat restaurant recipes as I can at home. You no longer have to try and stash away extra small packets of Horsey Sauce when you visit Arby's.
You can easily make this sauce at home and not have a fridge full of condiments that you can't remember when you grabbed them and have no idea how old they are.
There is nothing quite like the mix of unknown condiments from restaurants stuffed in the butter drawer of a refrigerator.
We love Arby's and hope you love these other great recipe we have shared....Jamocha Shake and Arby's Sauce!
Ingredients
- Creamy Horseradish
- Mayonaise
- Sugar
- Salt
Horseradish - There are quite a few options for horseradish at the grocery store these days. I normally find it in the condiment section near the mustard. I highly suggest going with creamy horseradish to save yourself the step of having to blend the horseradish to get the chunks out of it. You can also find it on Amazon.
Equipment Needed
One of the best parts of this recipe is you don't really need any special equipment! All you need is a small bowl and a spoon.
We mix our Horsey Sauce in a larger bowl and then transfer it to a smaller container for chilling in the refrigerator. I like using a bigger bowl to mix everything together so I have space to really get all the ingredients combined.
Recipe Tips
Plan time for the Horsey Sauce to sit in the refrigerator for at least an hour. The longer this sauce sits in the fridge the better the flavors meld together and it tastes amazing.
I have heard of people mixing this horseradish sauce with a bit of sour cream and putting it on their baked potatoes.
