Step‑by‑Step Instructions for Air Fryer Blooming Onion

Step 1: Prepare the Onion
Start by cutting off about ½ inch from the top of a large sweet onion and carefully peel away the outer skin. Place the onion root-side down on a cutting board, ensuring it’s stable. Using a sharp knife, make four evenly spaced cuts down towards the root, without cutting through it, followed by three additional cuts in each section to create 16 distinct petals that will bloom beautifully in the air fryer.

Step 2: Relax the Petals
After cutting the onion, let it sit for about 5 minutes to allow the petals to relax slightly. This will help them separate more easily during cooking. You should see the petals starting to fan out, resembling a blooming flower, setting the stage for your Air Fryer Blooming Onion to shine.

Step 3: Mix the Coating
In a large mixing bowl, whisk together 2 ½ cups of all-purpose flour, 1 tablespoon of paprika, 1 teaspoon of cayenne pepper, ½ teaspoon of ground cumin, ½ teaspoon of dried thyme, and ½ teaspoon of dried oregano. This flavorful mix will create a crispy exterior for your blooming onion, enhancing its taste with a delightful spice blend.

Step 4: Prepare the Egg Wash
In a separate bowl, whisk together 2 large eggs, 1 cup of milk, and 1 cup of water until well combined. This egg wash will help adhere the flour mixture to the onion. Ensure it is smooth and evenly mixed, as this will play a key role in achieving that crispy, golden texture.

Step 5: Coat the Onion
Carefully coat the onion petals with the flour mixture, ensuring to get some in between each petal for maximum coverage. Afterward, dip the entire onion into the egg wash, allowing any excess to drip off. Return the onion to the flour mix for a second coat, ensuring it’s generously covered before proceeding to the next step.

Step 6: Chill and Preheat
Once coated, place the onion in the refrigerator for about 10 minutes while you preheat your air fryer to 350°F. This chill time helps set the coating, leading to an even crispier finish. It’s essential to preheat the air fryer to ensure the best cooking results, so don’t skip this important step!

Step 7: Prepare for Air Frying
After chilling, lightly spray the coated onion with oil using a refillable spray bottle for even coverage. To make transferring easier, create a sling using aluminum foil to hold the onion. Gently place the onion in the air fryer basket, positioned upright and secure, ready for cooking.

Step 8: Air Fry the Onion
Set the air fryer to cook the blooming onion for 20-25 minutes. During the cooking process, spray the onion with oil 2-3 times to enhance crunchiness and achieve a rich, golden brown color. Around the halfway mark, you might want to check on it to ensure even cooking and maximum crispiness.

Step 9: Serve and Enjoy
Once the Air Fryer Blooming Onion is beautifully golden brown and crispy, carefully use the aluminum foil sling to remove it from the air fryer. Let it cool slightly before serving it warm with your favorite dipping sauce. The stunningly crispy petals are perfect for sharing, making this appetizer a showstopper at any gathering!

Expert Tips for Air Fryer Blooming Onion

Sharp Knife Needed: Use a sharp knife to achieve clean cuts in the onion without crushing the base. This ensures a better bloom during cooking.
Preheat for Perfection: Always preheat your air fryer; it’s essential for achieving that irresistibly crispy texture in your Air Fryer Blooming Onion.
No Aerosol Oils: Stick to a refillable spray bottle for oil. Aerosol oils can affect your air fryer’s performance and cooking results.

Air Fryer Blooming Onion Recipe FAQs

How do I choose the perfect onion for blooming?
Absolutely! Look for a large sweet onion that is firm and without soft spots. The onion should feel heavy for its size, and a smooth, dry outer skin is best. Avoid any onions with dark spots, as these may affect the flavor and texture when cooked.

How should I store leftovers from the Air Fryer Blooming Onion?
To keep your Air Fryer Blooming Onion fresh, store any leftovers in an airtight container in the refrigerator for up to 2 days. While the flavor will still be delightful, the crispiness may diminish, so I recommend reheating it in the air fryer to restore some of that crunch!

Can I freeze my Air Fryer Blooming Onion, and how?
Yes, you can freeze your blooming onion! Prepare the onion and coat it as instructed, then place it on a baking tray and freeze until solid. Once frozen, transfer it to a freezer bag and store it for up to 1 month. When you’re ready to enjoy it, air fry straight from the freezer at 350°F for about 12-15 minutes until crispy and heated through.

What should I do if my onion doesn’t bloom properly?
If your onion doesn’t bloom as expected, it could be due to uneven cuts or not letting the petals relax before cooking. Next time, make sure your cuts are clean and avoid cutting through the root entirely. If you notice some petals are sticking together, gently separate them before cooking and allow the onion to sit for 5 minutes as suggested.

Are there any dietary considerations I should be aware of?
Indeed! If you’re making this for someone with gluten sensitivities, feel free to substitute the all-purpose flour with a gluten-free flour blend. For a dairy-free option, simply replace milk with your preferred plant-based milk. Just remember that the egg is essential for binding, so no substitutes are recommended for that ingredient. Enjoy your indulgent Air Fryer Blooming Onion without worries!
