I don’t know about you, but I have been missing all my favorite restaurant favorites lately. Since we have been home, I have been working hard to recreate those favorites and make copycat versions. If you are one of the Bloomin' onion lovers, you will want to stick around for this recipe!

I love the Outback Steakhouse Blooming Onion from their original menu. Have you ever had one? If not, you are missing out! This blooming onion recipe is my favorite. It's a popular appetizer and one of the best copycat recipes I have made to date.

You can also make their new recipe, the Onion Petals if you prefer those over the Blooming Onion.

But – no fear! Today, I have the perfect copycat version for you made with the delicious sweet Vidalia Onions

How to Make Copycat Outback Steakhouse Blooming Onion

So why am I using Vidalia Onions?

If you know anything about a blooming onion, then you know the kind of onion you use is super important. Vidalia Onions are perfect for this because they are sweet onions with the best flavor.

These onions are perfect for spring and summer. Most harvest hits the stores in April and usually by the end of summer, they are gone. 

If you are lucky enough to find these in the store, stock up because they are great in so many dishes, but for this recipe, Vidalia Onions are the ONLY onion you will want to use.

So – let’s get started . . .

Start by using a cutting board and chop off the end of the onion with a sharp knife.

Once you chop off the end, remove all the peel but leave the hairy end of the onion intact.

Now, using your knife, flip the whole onion over and make ½ inch cuts all around the onion to create petals. Be sure to watch how far you go down. Do not cut through the center of onion will fall apart as you are frying it.

Once you cut the onion into 12-16 vertical wedges, place it in an ice-cold water bath with the top of the onion (where the bottom root end) facing up and the petals down in the water. This will help the onion petals to open up.

In a large bowl, mix all your dry ingredients – flour, paprika, cayenne pepper, seasoned salt, garlic powder, oregano, and black pepper and set aside.

In another bowl, whisk together the eggs and milk. 

Dip the onion in the flour mixture making sure to coat each petal. The reason you dip in the flour first is to make sure your breading sticks and does not fall off. Knock off any excess flour.

Now, dip in the milk and egg mixture, being sure to coat each petal. Then, dip again in the dry mixture. 

Now, put your onion on a parchment-lined sheet pan and stick it in the freezer for about 30 minutes. 

While the onion is freezing, get your vegetable or peanut oil heated and make your bloom sauce. The sauce, as you know, is where it’s at when it comes to a blooming onion.

I like a sauce with a kick, so I add fresh horseradish to mine, but if you do not like a spicy kick, you can leave it out. You can also add in some sour cream for a creamy texture.

Let’s Fry That Beautiful Blooming Onion!

Once your onion has been in the freezer for at least 30 minutes, heat your oil in a large pot like a Dutch oven until it reaches 400 degrees. Of course, you can also use a fryer with a fryer basket.

Gently place your onion in the hot oil, cut side down first, and fry on medium-high heat for about 3 minutes to get that golden brown look.

Turn your oil down to about 350 degrees (medium) and flip it over to cook the other side. Cook for about 9 minutes until everything is golden brown. 

Once the onion is golden brown, remove it from the oil with a wire skimmer and place it on a few paper towels so that it can drain. Sprinkle with kosher salt and enjoy!

Serve with your delicious Bloomin Onion Sauce sauce for the perfect comfort food appetizer. Once you learn how to make these at home, you won’t even need to worry about going out to the restaurant!

You can also try making a Loaded Blooming Onion topped with cheese sauce and all the fixings!

The next time you want to make this, try making it in an air fryer. You can get the same crispy texture without the oil.

Of course, you can also use this recipe to make onion rings if you prefer them to the whole onion.

Blessing my family like this is just one of the sweet moments of my day. I love cooking their favorites and surprising them with dishes that they miss. 

As I said, you can make easy recipes like this too and Vidalia Onions is a great place to start! What is your favorite comfort food that is filled with delicious onion flavor?
