Outback Steakhouse Blooming Onion
I think this is one of one my first copycat recipes. I can remember the first time I tried this bloomin onion. An onion is sliced in a way that it opens up, some might even say it “blooms”.
The petals are battered, and the onion is deep-fried and then this creation is served with a wonderful sauce. I know you will be blown away just like I was the first time I tried this creation.
Ingredients
What you’ll need for making a blooming onion:
- Cornstarch
- Minced garlic
- Salt
- All-purpose flour
- Paprika
- Pepper
- Beer
- Garlic powder
- Cayenne pepper
- Vidalia onions or other large sweet onions
- Oil for frying
- Bloomin Onion Sauce for serving

Ingredient Notes
A sweet onion will give the perfect flavor. Use a Vidalia or 1015 onion.
My preference for cooking oil is peanut oil followed by vegetable oil. Any liquid oil will do, but I think peanut makes the onion crispier.
How to Prepare a Bloomin Onion
Preparing this onion isn’t too difficult. Basically, you’ll make a seasoned beer batter and flour mixture, cut and batter the onion, then deep fry it. Here are the step-by-step instructions:
- Mix cornstarch, minced garlic, flour, paprika, and pepper until well blended.
- Add the beer and mix well until the batter is well combined.

- Combine flour with garlic powder, cayenne pepper, paprika, and pepper. Mix until well blended.
- Peel the onions and place the root side on the cutting board. Use a sharp knife to slice the first 3/4 inches off the top of the onion. Then you will make 10 to 12 verticle cuts, but don’t go all of the way to the root.
- Separate the onion petals slightly, but do not do this too much or you will destroy the onion.

- Dip the onions into the seasoned flour and shake off the excess flour.
- Dip the onions into the batter and separate the petals to ensure they are thoroughly coated.
- Then dip the onion into the seasoned flour again.

- Heat the oil in a deep fryer until the oil temperature is 375 to 400°F. Gently place the onion in the fryer basket and deep-fry for 1½ minutes on one side. Flip the onion and fry for an additional 1½ minutes.
- Drain on paper towels.

- Place the onion on a plate and serve it hot with Bloomin Onion Sauce.

Recipe Tips
You may want to make sure your cutting board has a damp cloth under it so it doesn’t move.
If desired, you can cut out the center of the fried blooming onion and put a small cup of dipping sauce in it.
If you feel cutting the blooming onion is too much, then try cutting it into petals, strings, or onion rings.
Be sure to serve it with plenty of bloomin onion sauce.
