Step‑by‑Step Instructions for Crispy Mini Blooming Onions in Air Fryer
Step 1: Prepare the Onions
Begin by peeling your small onions and carefully cutting about half an inch off the tops, making sure to leave the roots intact. Creating a blooming effect, slice the onions into petals by making vertical cuts from the top towards the root, ensuring they stay connected at the base. This will allow for even cooking and make the Crispy Mini Blooming Onions look appealing.
Step 2: Mix Flour Coating
In a large mixing bowl, combine the all-purpose flour, paprika, garlic powder, salt, and black pepper, whisking until well blended. This mixture will provide a flavorful and crispy coating for your onions. Keep it nearby as you continue to prepare the egg wash and breadcrumb station—having everything organized will ensure a smoother coating process.
Step 3: Prepare Egg Mixture
In a separate bowl, whisk together the large eggs and buttermilk until combined and slightly frothy. This egg wash is crucial for binding the coating to the onions, ensuring the crispy texture you desire. Once mixed, have this bowl ready for the fun part—coating those blooming onions and getting them prepped for the air fryer!
Step 4: Coat the Onions
Take each prepared onion and first dip it into the flour mixture, ensuring it’s well coated. Next, transfer it to the egg wash, making sure to let any excess drip off, before rolling it in the breadcrumb mixture for a final crispy coating. This triple-layering technique will give you the perfect Crunch for your Crispy Mini Blooming Onions, so repeat this for all the onions.
Step 5: Air Fry
Preheat your air fryer to 375°F (190°C) for optimal cooking. While it’s heating, carefully spray the basket with cooking spray to prevent sticking. Place the coated onions in the basket without overcrowding, ensuring air can circulate around each piece. Air fry for 15-20 minutes, checking halfway through for a golden brown color and a crispy texture that typically indicates they are ready.
Step 6: Serve
Once your Crispy Mini Blooming Onions are perfectly golden brown and crisp, carefully remove them from the air fryer. They are best enjoyed fresh, so serve them immediately while they’re hot with your favorite dipping sauces like ranch or spicy mayo. These delightful appetizers will be the highlight of any gathering!

Expert Tips for Crispy Mini Blooming Onions
• Root Intact: Always leave the root attached when cutting the onions. This prevents the petals from falling apart during frying, ensuring beautiful, intact blooms.
• Breading Technique: Use one hand for the dry ingredients and one for the wet to keep things tidy. This prevents clumping and creates a perfectly crispy coating for your Crispy Mini Blooming Onions.
• Don’t Overcrowd: Air fry in batches! Overcrowding can lead to uneven cooking and soggy petals. Give each onion space to crisp up nicely.
• Flavor Boost: Experiment with spices! Adding a pinch of cayenne or Italian herbs to the flour mix can give your blooming onions an extra layer of delicious flavor.
• Storage Tip: For the best texture, enjoy immediately. If you have leftovers, store them in an airtight container in the fridge for up to 2 days and reheat in the air fryer for crispiness.
