What is Horseradish?

Horseradish is a large, beige colored, root vegetable. It is pungent and spicy, with a huge kick of flavor. To be honest, it reminds me of wasabi or garlic because it really clears out your sinuses.

Fresh horseradish root is typically grated very finely and preserved in vinegar, salt, and a little sugar. This prepared horseradish is what we find at the grocery store and what we will use in this aioli recipe.

Horseradish Aioli Ingredients

This horseradish sauce is only 7 simple ingredients. Below are a few notes on each ingredient and potential substitutions.

  • MAYONNAISE: Use your favorite, just make sure you are not use Miracle Whip. I use reduced fat olive oil mayo.
  • SOUR CREAM: Make sure it is full fat for ultra creaminess. Greek yogurt can be used in it’s place.
  • HORSERADISH: Prepared horseradish (homemade or store bought) is better than fresh horseradish. The fresh stuff tends to be a little too overpowering. If you have fresh horseradish use this recipe to prepare it.
  • GARLIC: Always use fresh garlic cloves, bottled minced garlic or garlic powder just isn’t the same. Use a zester grater to grate the clove finely (it’s easier than mincing or using a garlic press).
  • LEMON JUICE: Freshly squeezed tastes the best. Stay away from bottled lemon juice for this aioli.
  • SALT: This is going to help cut through the acidity from the lemon juice (don’t skip this).
  • BLACK PEPPER: To add an additional flavor note.
Ingredients. Mayonnaise, sour cream, lemon juice, prepared horseradish, fresh grated garlic, salt, pepper.

How to Make Horseradish Aioli Sauce

Here is a quick overview on how to make horseradish sauce, the recipe card will have complete details.

  1. STIR TOGETHER mayonnaise, sour cream, prepared horseradish, grated garlic cloves, fresh lemon juice, salt, and black pepper. Don’t forget to taste test the aioli and adjust it to your taste preferences.
  2. POUR INTO A GLASS JAR or airtight container and store in the refrigerator.
  3. REFRIGERATE at least one day prior to using (this helps build the flavor). You can eat it immediately but I find it tastes even better the next day.

Storing Information

Your horseradish sauce should always be stored in an airtight container or jar and in the refrigerator. It will last for 7 to 10 days. Always stir it and check your aioli sauce for mold spores or a foul sour smell before eating.

3 Tips For The BEST Horseradish Aioli

ALWAYS TASTE TEST YOUR HORSERADISH. Prepared horseradish comes in all potencies, some are extra hot while others are mild. Feel free to alter the amount of prepared horseradish to suit your taste preferences. I like horseradish sauce on the spicier side.

USE HIGH QUALITY OR HOMEMADE MAYONNAISE (not Miracle Whip) for the best taste. Since it is the majority ingredient you don’t want to use a mayo you don’t like the taste of.

CHILL OVERNIGHT FOR EVEN BETTER FLAVOR. As the ingredients chill they meld together and amplify. It is kind of like steeping tea in water. The horseradish, garlic, and lemon will flavor the mayo and sour cream.

Here are a few more ways you can use your Horseradish Aioli:

Frequently Asked Questions (FAQ’s)

What type of horseradish should I use in horseradish aioli?

I used homemade prepared horseradish. Alternatively you can use store-bought horseradish or freshly grated horseradish. Keep in mind, some horseradish is spicier and more pungent than others. Taste test and alter the amount as needed.

Can Horseradish Aioli be frozen?

No, I do not recommend freezing this aioli because it separates and becomes an odd texture when thawed.

Can Horseradish Aioli be made ahead of time?

Yes. For best results, I recommend refrigerating the sauce no more than 1 to 3 days prior to using. Be sure to stir it well before serving and eating.
