This horseradish aioli recipe has a kick perfect for smearing on sandwiches or dipping into it with fries. This is a traditional aioli recipe made from scratch in less than 5 minutes.
In a medium bowl, whisk together the egg yolks until smooth. Very gradually, pour in the oil in a steady stream. You can use as little as 1 cup of olive oil. Stop adding once the mayonnaise becomes thick.
Once all of the oil is incorporated and the mayonnaise is thick and creamy, whisk in the salt, lemon juice, and horseradish until fully combined.
Taste and adjust seasoning as needed, adding more lemon juice for acidity or horseradish for a spicier aioli. Chill for 30 minutes before serving.
Notes
Make sure to use pasteurized eggs since they are not cooked.
To use fresh horseradish use a 1:1 ratio and increase the lemon juice to 2 tablespoons or add an additional teaspoon of Dijon mustard.
I prefer to use an immersion blender for this recipe but you can use a regular blender or a small bowl and whisk by hand.
Make up to a week in advance. Store it in an airtight container in the refrigerator.
