You only need a few basic ingredients to make them – flour, eggs, panko breadcrumbs, and some simple seasonings. Nothing fancy or hard to find.

Tips
Pick the Right Onions
Go with large sweet yellow onions for this recipe. They caramelize nicely in the air fryer and have a mild flavor that works perfectly with the crispy coating.
Avoid white onions or red onions here. White onions can be too sharp and pungent, and red onions tend to turn a weird grayish color once cooked, which doesn’t look great.
If you can find Vidalia onions, those are even better. They’re naturally sweeter and give you that classic blooming onion flavor you get at restaurants.
Separate the Onion Layers Carefully
After you cut the onion into wedges, take your time peeling apart the layers into individual pieces. You want each piece to be roughly the same size so they all cook at the same rate in the air fryer.

Try to keep the pieces around 2-3 layers thick at most. If a piece has too many layers stuck together, the breading won’t stick well in the middle and the inside layers will be undercooked and soft.
If some of the tiny inner pieces are too small to bread properly, just set those aside. You can toss them in a bag and use them for cooking something else later.
Pat the Onion Pieces Dry
Before you start the breading process, lay your onion pieces on a paper towel and pat them dry. Onions have a lot of moisture, and if they’re wet, the flour won’t stick properly and your coating will slide right off during cooking.
This step takes about 30 seconds and makes a huge difference. Dry onion pieces grab onto the seasoned flour much better, which means the egg and panko layers stick better too.

Frequently Asked Questions
What type of onion works best for blooming onion bites?
Large yellow onions are the best choice because they have a nice balance of sweetness and flavor that really comes through once they are air fried. They also hold their shape well during cooking, which helps the coating stay on.
You can use sweet onions like Vidalias too if you prefer a milder, sweeter taste. Red onions will work in a pinch, but they can be a bit sharper and the color may bleed into the breading.
