The air fryer works its magic on this golden-brown blooming onion, filling your home with an amazing smell. You'll get all the satisfying crunch of the restaurant favorite without dunking it in a vat of oil. Every petal gets coated in tasty seasonings, and the homemade sauce takes this crowd-pleaser to a whole new level of yumminess.
I've whipped this up so many times for family get-togethers, and folks always wander into the kitchen asking what smells so good. Even my onion-hating nephew asks for more when I make this version.
Must-Have Ingredients and Smart Shopping Advice
- Sweet Vidalia Onion: Go for a big, solid one with a flat bottom so it stands up nicely in your air fryer
- All-Purpose Flour: The unbleached kind gives slightly nicer color, but both types work great for that crunchy outside
- Paprika: Grab Hungarian sweet paprika for its beautiful color and mild sweetness that makes the onion taste even better
- Buttermilk: Go for the real stuff, not the vinegar-milk mix, as it helps the coating stick perfectly
- Japanese Mirin: This hidden hero in the sauce brings just enough sweetness to balance out the mayo
- Quality Mayonnaise: Don't skimp here - full-fat mayo makes for a much tastier dip
How To Make It Happen
- Getting The Onion Ready:
- Cut off the top quarter-inch but keep the root end intact. Carefully remove the outer skin while making sure the root stays solid. Cut the onion into quarters but stop before reaching the root. Keep cutting each section until you have 16 evenly spaced cuts. Soak in ice water for 15 minutes to help the petals open up naturally.
- Making Your Coating:
- Mix all dry stuff until the spices spread evenly through the flour. Mix eggs and buttermilk until they're completely blended together. Set up your coating station in this order: flour mix, egg wash, and an empty plate.
- Adding The Coating:
- Dry the onion completely with paper towels for maximum crispiness. Start from the middle and sprinkle flour between all the petals. Turn the onion around to coat the outside evenly. Pour the egg mix between all layers, making sure everything gets covered. Go back to the flour mix for one last coat, pressing it onto each petal.
- Air Fryer Magic:
- Get your air fryer hot for 5 minutes at 375°F. Spray the basket with olive oil so nothing sticks. Put the onion in root-side down. Spray it all over with olive oil, making sure there's no dry flour showing. Cook for 5 minutes, then check how it's browning. Spray any pale spots and keep cooking. After another 5 minutes, check if the petals are crispy. If needed, add a bit more oil and cook 2-3 minutes longer.

Picking The Perfect Onion
Sweet onions get almost candy-like when cooked, creating an awesome balance with the seasoned coating. I found this out the hard way when I used a regular yellow onion once. It wasn't bad, but it missed that special sweet-savory combo that makes this dish so addictive.
Creating The Ultimate Dip
The sauce isn't just a sidekick - it's half the reason this dish rocks. Let it chill in the fridge while you cook everything else so the flavors can mix together. I've learned that adding the melted butter last while constantly stirring gives you the creamiest texture possible.
