One of those is the Outback Steakhouse Blooming Onion from their original menu. Have you ever had one? If not, you are missing out!

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 of their super sweet 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 chopping off the end of the onion.

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 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 all the way through or your onion will fall apart as you are frying it.

Mix together all your seasonings – 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.

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 in the freezer for about 30 minutes. 

While the onion is freezing, get your oil heated and make your dipping 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 spicy kick, you can leave it out.

Let’s Fry That Beautiful Blooming Onion!

Once you onion has been in the freezer for at least 30 minutes, heat your oil in a large pot until it reaches 400 degrees.

Gently place your onion in the oil, cut side down first and fry 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 from the oil and place on a paper towel lined plate to drain.

Serve with your delicious dipping 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!

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?
