How to Make a Blooming Onion
Prepare the Onion: Start by cutting off about ½ inch from the top and bottom of a large onion, leaving the root intact. Peel off the skin and discard it. Place the onion cut-side down on a cutting board.
Create the Blooming Effect: Starting from the top, make vertical cuts about ½ inch apart, going down toward the root but being careful not to cut all the way through. Rotate the onion 90 degrees and make the same vertical cuts, creating a crisscross pattern.
Batter the Onion: In a mixing bowl, combine 125g of all-purpose flour, 1 tablespoon each of paprika, garlic powder, and salt, along with 1 teaspoon of black pepper and optional cayenne pepper. In another bowl, pour 240g of buttermilk. Dip the onion into the buttermilk, ensuring it's thoroughly coated, then transfer it to the flour mixture. Gently press the flour mixture into the crevices to evenly coat the onion.
Heat the Oil: Fill a large deep fryer or heavy-bottomed pot with vegetable oil and heat it to 350°F (175°C). Use a cooking thermometer to ensure the oil reaches and maintains the correct temperature.
Fry the Onion: Carefully lower the coated onion into the hot oil using tongs or a slotted spoon. Fry for 10-15 minutes or until golden brown and crispy. For even cooking, flip the onion halfway through the frying time.
Drain and Serve: Once cooked, carefully remove the blooming onion from the oil using tongs and place it on a plate lined with paper towels to drain excess oil. Allow it to cool for a few minutes, serve with your favorite dipping sauce, and enjoy!
Tips and Tricks for the Perfect Blooming Onion
Be Precise with Cuts: Using a sharp knife, aim for cuts that are as evenly spaced as possible. The uniformity of your cuts contributes to the onion "blooming" symmetrically during frying, resulting in a visually stunning presentation. The goal is to create that captivating, flower-like appearance when it opens in the fryer.
Test Oil Temperature: Don't underestimate the importance of maintaining the correct oil temperature. A cooking thermometer can help ensure your oil is consistently at 350°F (175°C). An oil temperature that's too high can lead to a burnt exterior, while too low can make the onion greasy and unappetizing.
Turn for Even Cooking: Halfway through the frying process, use tongs to gently flip the onion. This helps achieve a uniform golden-brown hue across all layers. Be cautious while turning to avoid dislodging the batter.
Drain Well: After achieving that ideal golden-brown color, allow the onion to drain on paper towels. This will absorb excess oil and help maintain the crispy texture for a longer period, ensuring that each bite remains satisfying.
Prevent Soggy Petals: The consistency of your batter plays a significant role in how crispy your Blooming Onion turns out. If the batter is too thick, it may not cook through, leaving you with a soggy result. Aim for a batter consistency that is thick enough to coat the onion but will also cook thoroughly.

Blooming Onion - FAQ
A large, firm, and round onion is generally the best choice. While Vidalia onions are often recommended for their sweetness and size, any large yellow or white onion will work well.
es, you can make a Blooming Onion in an air fryer. However, the texture might not be as crispy as when deep-fried. Be sure to spray the battered onion generously with cooking spray and cook at 375°F for about 15-20 minutes, checking for doneness.
The key is in the cutting. Make sure to cut the onion into evenly spaced slits, avoiding cutting all the way through to the root. After you've battered the onion, you can also gently separate the "petals" a bit with your fingers to encourage it to bloom while frying.
Dipping the onion in buttermilk before coating it in the flour mixture helps the batter adhere better. Make sure to press the flour mixture into the crevices of the onion for an even coating.
A soggy Blooming Onion could be the result of oil that is not hot enough, or a batter that is too thick. Make sure your oil is at a consistent 350°F and check the consistency of your batter.
