Copycat Sauce

This is a copycat sauce based on Outback Steakhouse’s Blooming Onion sauce. It is very creamy with a base of mayonnaise and sour cream.

Cayenne pepper and horseradish give it a great kick, for the ultimate in spicy dipping sauces.

Make Ahead

This sauce is best when it has an hour or two to rest in the refrigerator after it is made. The cooling time helps all the flavors meld together.

You can make it a few days ahead of time if you like. This blooming onion sauce will keep in the refrigerator for about 2 weeks after you make it.
