Ingredients
For the Batter:
1 cup buttermilk (or milk mixed with 1 tbsp lemon juice)
1 cup flour (or gluten-free flour)
1 tablespoon paprika (smoked paprika optional)
1 teaspoon garlic powder
1 teaspoon onion powder
1/2 teaspoon salt
1/2 teaspoon black pepper
For the Onions:
6–8 small onions (peeled)
Cooking spray or a light drizzle of oil
How to Make Air Fryer Mini Blooming Onions
Step 1: Prepare the Onions
Peel the onions and trim the root slightly so they can sit flat. Carefully cut each onion into quarters or eighths (like petals), making sure not to cut all the way through the base.
Step 2: Soak in Buttermilk
Place the onions in the buttermilk mixture and let them soak for at least 15–20 minutes. This helps soften them and allows the coating to stick better.
Step 3: Make the Coating
In a bowl, mix the flour, paprika, garlic powder, onion powder, salt, and black pepper.
Step 4: Coat the Onions
Remove the onions from the buttermilk and dredge them in the flour mixture. Make sure to coat between the layers for maximum crispiness.
Step 5: Air Fry
Preheat your air fryer to 180°C (350°F). Place the onions in the basket in a single layer. Lightly spray with cooking oil.
Air fry for 12–15 minutes, or until golden brown and crispy.
Tips for Perfect Crispy Blooming Onions
