The blooming onion sauce is super easy to make – I usually mix it ahead of time and keep it in the refrigerator until I’m ready to serve it. All of the details for making it are in the recipe card at the end of the post!
How to Cut the Onion
Basically, we’re cutting it so it looks like a blooming flower. It’s not hard to do, but be sure your knife is sharp before you start cutting.
- Cut a 1/2” off the end opposite the root end. You will want the root intact as that is what will hold it together once it’s “blossomed”. Remove the outer skins and discard them.
- Place it cut-side down on your cutting board so the root end is facing up.
- Position your knife about a ½” lower than the root and slice into the onion towards the middle and pull the knife down to the cutting board. Repeat this process four more times, evenly spacing each slice around the onion.
- Now, slice each section in half that you already did, evenly spacing each cut. At this point, you will have eight total cuts.
- Repeat this again, slicing each section again so you have 16 even cuts all around the onion.
Turn it over and let it sit for a few minutes so the petals relax and open up. While it rests, you can prepare the breading and batter.
Breading and Batter
Flour Mixture: In a large bowl, whisk the flour and spices together.
Batter: In a medium bowl, whisk the eggs, milk, salt and pepper with water until smooth.
At this point, you are ready to do the breading and batter steps. Before you do, gently separate the petals so they are splayed open. Be careful not to break or pull them out from the root.
Double Breading Steps
1st Flour Coating: Place the onion in a separate bowl, cut-side up, and pour the flour mixture over the top. Use a spoon to coat it in the mixture making sure to coat in between each petal. Carefully lift it from the bowl, turn it over, and gently pat to off the excess flour mixture.
Batter Coating: Place it in the batter in the other bowl and evenly coat it. Lift it out of the bowl and allow the excess to drip off.
2nd Flour Coating: Place it back in the bowl with the flour and use the spoon to coat it evenly. Once done, lightly pat it again to remove the excess coating and then place it in the refrigerator to chill while you get the deep-fry oil ready.
How to Fry It
Fill your pot with enough oil so once the onion is added it will be covered. Heat the oil to 400 degrees F. While the oil heats, place a wire baking rack over a few paper towels.
Remove the breaded onion from the refrigerator and tap off any excess breading. Place it on a wire skimmer and carefully lower it into the hot oil. Once you add the oil temperature will drop, so maintain the heat so the oil is 350 degrees while the onion is cooking.
Fry it for about three minutes and then carefully turn it in the oil and fry it for three more minutes or until it’s golden and crispy.
Using the wire skimmer, carefully lift it out of the oil and transfer it to the baking rack to drain. Serve hot with the sauce on the side!
- The best onion to use is a sweet variety. I don’t recommend using red onion for this recipe!
- The best oil for deep-frying is one that has a high smoke-point like canola oil, vegetable oil, or peanut oil.
- For best results, be sure to use a thermometer when you fry! This will take all of the guesswork away and you will avoid burning the breading with oil that is too hot or ending up with soggy breading if it’s too cool.
- A heavy pot that retains heat well is best for deep frying.
- This recipe is for one blooming onion. If you are making more than one, I recommend frying them one at a time. If you overcrowd the pot they won’t cook evenly and it will be difficult to maintain the correct frying temperature.
- This is best served not long after it’s fried – it will maximize the crispy, crunchy breading! Because of this, they don’t keep well after they’ve been made – the breading will soften as they cool.
I feel like I should warn you because once you make this crispy golden treat at home your friends and family will beg you to make it all the time! The crispy petals taste just like onion rings but served up in a fun way. I hope you give this one a try soon!
