Outback Blooming Onion Sauce

This copycat Outback blooming recipe is a lighter version of the famous dipping sauce from the famous steak house.

When you go, you have to order the Blooming Onion appetizer. I will admit that when we ate there I also dipped my steak and chicken in the sauce.

Now that I’m sharing, let’s get real. I just dipped my fingers in it or ate it with a spoon.

Which is why I always made sure to order extra sauce on the side. If there was any left, I would take it home for later.

Now you don’t have to leave the comfort of your home and you can dip however you like. No one watching!!

What about some chicken wings? Are you drooling yet?

So what exactly is in this amazing sauce?

What is Blooming Onion Sauce made of?

Just like your other delicious, creamy, and addicting dips, it starts with mayo.

I have added sour cream in place of some of the mayo, but you can also use plain yogurt.

After that, it’s all about the horseradish for tanginess and the spices for that kick at the end.

Ingredients Needed

Mayo – You might have noticed that I love Dukes Real Mayo for all my recipes that use mayo. It’s the creamiest around. Feel free to use your favorite. I don’t recommend using Miracle Whip as it changes the flavor.

Ketchup – This is pretty standard and I don’t recommend using the sugar free or low sodium versions. They will change the overall flavor.

Sour Cream – Full fat, reduced fat, or fat free versions will work well. You can also use plain Greek yogurt.

Horseradish – This is a prepared horseradish which means it’s been ground and then mixed with vinegar and other spices. Be sure to get this and not fresh horseradish or horseradish sauce.

Herbs & Spices – Included in this recipe are paprika, oregano, cayenne pepper, garlic powder, salt & pepper.

Do you eat onion rings with ketchup?

I am not a huge fan of ketchup but added to other sauces like this one, I would dunk my onion rings in it!

How long does it last?

If stored in the fridge in an air tight container, this sauce will keep for up to a week. But, in my house, it never makes it more than 24 hours.

Can I freeze it?

Because of the mayonnaise and the sour cream, it does nor freeze well. Good thing it makes just the right amount:)

Forget the trip to Outback Steakhouse. Grill and home and enjoy!

You got the mayo right on the Bloom Sauce. Nothing else.

@Tony Cloninger, agreed. I didn’t add salt, used prepared horseradish sauce, and cut the ketchup in half. Also, oregano? Solid no. Also put a dash of sour cream in for thickening , mixed. Used a dash of smoked paprika and spritz of fresh ground pepper, a very small amount of cayenne, mostly for color. Solid copycat.
