For the Onions
• Whole Onions – 4 small, preferably sweet like Vidalia; they’ll provide a milder taste that enhances the overall flavor.

• Black Pepper – ½ teaspoon; adds a touch of mild heat and depth.
For the Coating
• Eggs – 2 large; these help bind everything together for a deliciously cohesive bite.
• Buttermilk – 1 cup; it adds richness and moisture, but yogurt or a dairy-free alternative will work well too.

Step‑by‑Step Instructions for Crispy Air Fryer Blooming Onions
Step 1: Prepare the Onions
Begin by peeling four small sweet onions, like Vidalia, and cut the tops off, ensuring you keep the root intact. Cut vertical slices around each onion, stopping just before the root to avoid slicing through. Gently pull apart the petals to reveal the blossoming shape, resembling a flower, and set them aside.
Step 2: Set Up Your Breading Station
Create a breading station by arranging three bowls. In the first bowl, mix together 1 cup of all-purpose flour with 1 teaspoon of paprika, 1 teaspoon of garlic powder, 1 teaspoon of salt, and ½ teaspoon of black pepper. In the second bowl, whisk together 2 large eggs with 1 cup of buttermilk. The third bowl will hold 1 cup of breadcrumbs, preferably Panko, to achieve that delightful crispy texture.
Step 3: Dredge the Onions
Take each prepared onion and first dredge it in the seasoned flour mixture, coating every petal generously. Next, dip the onion into the egg and buttermilk mixture, ensuring it’s fully submerged for an even coating. Finally, roll it in the breadcrumbs, pressing gently to ensure they stick well, creating a hearty layer of crunch on each blooming onion.
Step 4: Preheat the Air Fryer
Before cooking the blooming onions, preheat your air fryer to 375°F (190°C) for about 5 minutes. This step is crucial to ensure the onions cook evenly and turn golden brown. As the air fryer heats up, prepare your cooking spray, which will help achieve that irresistible crispiness.
Step 5: Air Fry the Onions
Once the air fryer is preheated, lightly spray the basket with cooking spray to prevent sticking. Place one coated blooming onion in the basket and give the top a light mist of cooking spray to enhance crispiness. Be careful not to overcrowd the basket; cook each onion one at a time for optimal results.
Step 6: Cook to Perfection
Air fry the first blooming onion for 15–18 minutes, keeping an eye on it as it cooks. You’ll know it’s done when the petals are a rich golden brown and the exterior is beautifully crispy. For an even cook, consider checking halfway through and rotating the onion for consistent browning.
Step 7: Serve Warm
Once the blooming onion is crispy and golden, carefully remove it from the air fryer using tongs and let it cool slightly. Display the blooming onion on a serving plate and serve immediately for the best texture and flavor. Pair it with your favorite dipping sauce for a delightful experience!
