How to Make Baby Blooming Onions in an Air Fryer
Step-by-Step Preparation and Cutting Guide
Creating baby air fryer blooming onions starts with a careful slice. Here’s how to prep your mini onions for that signature flower look:
- Peel and Trim: Start by peeling your small onions (pearl or cocktail). Trim just the top, leaving the root end intact to hold the layers together.
- Make the Cuts: Using a sharp paring knife, make 4–6 even cuts from top to bottom, like slicing a pie but stop just before the root so the petals stay attached.
- Soak in Buttermilk: Place the onions in buttermilk for 30–60 minutes. This tenderizes the layers and helps the coating stick.
Once soaked, you’re ready for dredging.

- Spray and Cook: Place onions in the basket and lightly spray with oil. Air fry for 10–12 minutes, flipping or shaking halfway through for even browning.
