How to Make Air Fryer Crispy Mini Blooming Onions
Ingredients:
- 1 cup Buttermilk (or milk with lemon juice)
- 1 cup Flour (substitute with gluten-free flour for a gluten-free option)
- 1 tbsp Paprika (consider using smoked paprika for extra flavor)
- 1 tsp Garlic Powder
- 1 tsp Onion Powder
- 0.5 tsp Cayenne Pepper (adjust according to taste)
- 1 tsp Salt
- 1 tsp Pepper
- 2 medium Sweet Onions (like Vidalia)
- As needed Cooking Spray/Oil (for crispy exterior)
Directions:
- Begin by preparing your mini onions. Peel the onions and cut off the top. Make several cuts from the top toward the bottom, being careful not to cut all the way through. You want the layers to open up like a flower.
- Soak the cut onions in buttermilk for at least 30 minutes. This helps the coating to stick better.
- In a bowl, mix flour, paprika, garlic powder, onion powder, cayenne pepper, salt, and pepper.
- Remove the onions from buttermilk and let the excess drip off. Dredge each onion in the flour mixture, ensuring even coverage.
- Preheat your air fryer to 370°F (188°C).
- Lightly spray or brush the onions with cooking spray or oil to promote crispiness.
- Place the onions in the air fryer basket, ensuring they are not crowded. You may need to do this in batches.
- Cook for 10-12 minutes, or until golden brown and crispy. Check halfway through and shake the basket to avoid sticking.
- Once done, remove the onions and let them cool for a few minutes before serving.
