This horseradish aioli recipe kicks up the flavor of creamy aioli with a punch of prepared horseradish blended into the rich mayonnaise base. The easy sauce delivers both tangy aioli flavor and zesty heat.
In your food processor, add the egg yolk, lemon juice, mustard, and vinegar. Season with a pinch of salt and pulse to mix two to three times.
Set the food processor to spin and slowly pour in the oil from the top
The egg and oil will combine and turn off-white, emulsifying into mayonnaise
Add the horseradish and Worcestershire sauce and pulse 3 to 5 more times to mix.
Spoon into a resealable jar and chill until ready to use.
Notes
If using jarred horseradish, be sure to buy a bottle that is fresh horseradish not horseradish cream sauce. You can usually find it in the refrigerator section near the deli. If it becomes too thick, use a ½ teaspoon cold water to thin it out.
