Tips & Variations
- Use smoked paprika instead of regular for a deeper smoky flavor.
- For a spicier kick, increase the cayenne pepper to 1 teaspoon or add a dash of hot sauce to the dipping sauce.
- Gluten-free flour works well if you need to avoid gluten.
- Make sure the onions are dry before dipping to get a crispier coating.
- If you don’t have an air fryer, baking in a convection oven at 400°F (200°C) on a wire rack can be a good alternative.
Storage
Store leftover crispy blooming onions in an airtight container in the refrigerator for up to 2 days. Reheat them in the air fryer at 350°F (175°C) for 3-5 minutes to restore crispiness. Avoid microwaving as it can make them soggy.

FAQs
Can I use regular milk instead of buttermilk?
Yes, you can make a buttermilk substitute by adding 1 tablespoon of lemon juice or vinegar to 1 cup of milk and letting it sit for 5 minutes before using.
Will these onions be as crispy as deep-fried?
While air-fried onions won’t be exactly the same as deep-fried, they still achieve a wonderfully crispy texture with a fraction of the oil, making them a healthier yet tasty alternative.
