How to Make Baby Air Fryer Blooming Onions
Step 1: Prepare the Onions
Peel the onions and carefully trim the root end only enough to remove any loose roots.
Keep the root end intact. This is important because it holds the onion together while you make the petals.
Place each onion root-side up on a cutting board.
Step 2: Cut the Onion Into Petals
Using a sharp knife, make several vertical cuts from the top toward the root, stopping about 1/2 inch before the root.
Continue making cuts around the onion until you have created several sections.
Be careful not to cut all the way through the root.
Turn the onion over and gently separate the sections with your fingers to create the blooming effect.
Repeat with the remaining onions.
Step 3: Prepare the Seasoned Flour
In a bowl, combine:
- Flour
- Paprika
- Garlic powder
- Onion powder
- Smoked paprika
- Salt
- Black pepper
- Cayenne pepper
Mix thoroughly.
Step 4: Prepare the Wet Mixture
In another bowl, whisk together the egg and buttermilk.
Make sure the mixture is smooth.
Step 5: Coat the Onions
Carefully dip each onion into the flour mixture, making sure the seasoning gets between the petals.
Shake off excess flour.
Dip the onion into the buttermilk mixture.
Then return it to the seasoned flour.
Coat it a second time, gently working the flour between the petals.
This double coating helps create a thicker, crunchier crust.
Step 6: Spray With Oil
Place the coated onions on a plate or tray.
Lightly spray all sides with cooking oil.
Don’t soak the onions in oil—the air fryer will do the rest.
Step 7: Air Fry
Preheat your air fryer to 375°F (190°C) if your model requires preheating.
Place the onions in the air fryer basket with enough space between them for air to circulate.
Air fry for approximately 12–16 minutes, depending on their size and your air fryer.
Gently check them halfway through cooking. If necessary, lightly spray any dry flour spots with a little more oil.
The onions are ready when the coating is golden brown and crispy and the onion inside is tender.
Step 8: Make the Dipping Sauce
While the onions cook, combine the mayonnaise, ketchup, horseradish, paprika, garlic powder, and cayenne pepper.
Mix until smooth.
Taste and adjust the seasoning as desired.
Refrigerate until ready to serve.
Step 9: Serve Immediately
Carefully remove the blooming onions from the air fryer.
Allow them to cool for a couple of minutes, then serve warm with the dipping sauce in the center.
Tips for Extra-Crispy Blooming Onions
Choose Small, Firm Onions
Small onions work particularly well for individual blooming onions. Sweet onions provide a naturally mild flavor, while yellow onions offer a stronger savory taste.
Don’t Cut Through the Root
The root acts like a natural anchor that keeps the onion together.
If you accidentally cut completely through it, the onion may fall apart.
Coat Between the Petals
The flour mixture needs to reach between the onion layers. Gently opening the petals while coating helps distribute the seasoning and creates a crispier result.
Don’t Overcrowd the Air Fryer
Air needs to circulate around the onions. If your air fryer is small, cook them in batches rather than placing them too close together.
Use Cooking Spray
A light coating of oil helps the flour brown and crisp. Too little oil can leave dry patches, while too much can make the coating greasy.
Easy Variations
Spicy Blooming Onions
Increase the cayenne pepper or add a little chili powder to the flour mixture.
Parmesan Blooming Onions
Add finely grated Parmesan cheese to the seasoned flour for an extra savory crust.
Ranch-Seasoned Onions
Add a little ranch seasoning powder to the flour mixture for a tangy variation.
Extra-Garlic Version
Increase the garlic powder or add a small amount of dried minced garlic to the coating.
Smoky Version
Use additional smoked paprika for a deeper, smoky flavor.

Frequently Asked Questions
Can I use regular onions?
Yes. Small yellow, white, or sweet onions can work. The flavor will vary depending on the onion you choose.
Do I have to use buttermilk?
No. If you don’t have buttermilk, regular milk can work. You can also make a quick substitute by adding a small amount of lemon juice or vinegar to milk and allowing it to sit for several minutes.
Why isn’t my coating crispy?
Usually, the coating needs enough oil and sufficient air circulation. Make sure you lightly spray the flour coating before air frying and avoid overcrowding the basket.
Can I make these ahead of time?
For the best texture, they’re best cooked shortly before serving. You can prepare the onions and coating ahead of time and refrigerate them until you’re ready to cook.
Can I reheat blooming onions?
Yes. Reheat them in the air fryer at around 350°F (175°C) for a few minutes until warmed and crisp again. Avoid the microwave if you want to maintain the crispy coating.
Final Thoughts
These Baby Air Fryer Blooming Onions are a fun way to turn simple onions into a crispy, restaurant-style appetizer at home. The seasoned coating gives them plenty of flavor, while air frying creates golden, crunchy petals without the need for deep-frying.
For the best results, keep the root intact, coat the petals thoroughly, give them a light spray of oil, and avoid overcrowding the air fryer.
Serve them hot with your favorite dipping sauce and watch them disappear!
