Step‑by‑Step Instructions for Crispy Mini Blooming Onions in Air Fryer
Step 1: Prepare the Onions
Begin by peeling the small onions, removing the outer layers gently. Carefully cut into the onion from the top, creating petal-like sections while ensuring the root remains intact; this keeps the onion together. Rinse them lightly to remove any excess skin and pat dry. This preparation sets the foundation for your Crispy Mini Blooming Onions.
Step 2: Mix the Flour Coating
In a mixing bowl, combine all-purpose flour, paprika, garlic powder, salt, and black pepper. Stir well until the dry ingredients are evenly mixed. This flavorful coating will provide that crunchy texture you crave. Set aside to prepare for the next step. You’ll want to have everything ready for seamless coating of your onion petals.
Step 3: Prepare the Egg Mixture
In a separate bowl, whisk together the eggs and buttermilk until smooth and homogenous. This egg mixture acts as a crucial binder for your Crispy Mini Blooming Onions, allowing the flour coating to adhere perfectly. Make sure there are no lumps in your mixture for an even coating.
Step 4: Coat the Onions
Begin coating each prepared onion by first dipping it into the flour mixture, ensuring each petal is thoroughly coated. Next, submerge it into the egg mixture, allowing the excess to drip off, and finally, roll it in the breadcrumbs for that perfect crunch. Repeat this process for each onion, ensuring they are well-covered for optimal flavor and texture.
Step 5: Air Fry
Preheat your air fryer to 375°F (190°C). Once heated, lightly spray the coated onions with cooking spray to enhance their crispiness. Arrange them in the air fryer basket, making sure to leave space between them for even air circulation. Cook for 15-20 minutes, or until they turn a beautiful golden brown color.
Step 6: Serve
Remove the Crispy Mini Blooming Onions from the air fryer and let them cool slightly. Serve warm for the best crunch and flavor, paired with your favorite dipping sauces like ranch or spicy mayo. Enjoy the delightful experience of breaking apart those crispy petals while savoring the deliciousness inside!

Crispy Mini Blooming Onions in Air Fryer Recipe FAQs
What type of onions should I use for blooming onions?
Absolutely! Small onions, like pearl or shallots, work beautifully for creating mini blooming onions. Their manageable size allows for easier handling, and the flavor profile remains sweet and mild. Just make sure to keep the root intact to hold those adorable petals together while cooking.
How should I store leftovers from this recipe?
I recommend storing any leftover Crispy Mini Blooming Onions in an airtight container in the refrigerator for up to 2 days.
