Introduction

The Air Fryer Blooming Onion is a crispy, flavorful appetizer that’s perfect for sharing. This take on the classic fried onion uses an air fryer, resulting in less oil but all the delicious crunch and spice. It’s a fun dish to serve at parties or enjoy as a snack.

A large white plate holds a crispy blooming onion with many petal-like layers fanned out in a circular pattern, each layer golden brown with a crunchy texture and some darker fried edges. Next to the onion, there is a small white bowl filled with creamy, light pink dipping sauce, with one onion petal dipped in it. The plate and bowl sit on a wooden board, all placed on a white marbled surface, and a glass with a golden drink is partially visible in the top left corner. A blue and white striped cloth is seen on the right side. photo taken with an iphone --ar 4:5 --v 7

Ingredients

1 large sweet onion
2 ½ cups all-purpose flour
1 tablespoon paprika
1 teaspoon cayenne pepper
½ teaspoon ground cumin
½ teaspoon dried thyme
½ teaspoon dried oregano
2 large eggs
1 cup milk
1 cup water
Salt and pepper to taste
Oil in a spray bottle (vegetable oil recommended)

Instructions

Step 1: Cut off ½ inch from the top of the onion and peel away the outer skin. Place the onion cut-side down.
Step 2: Starting about ½ inch from the root, make a downward cut all the way through to the cutting board. Repeat to make four evenly spaced cuts around the onion.
Step 3: Make three additional cuts between each section, resulting in 16 evenly spaced cuts. Turn the onion over and set aside for 5 minutes to allow the petals to relax.
Step 4: Gently separate the outer petals with your fingers before breading.
Step 5: In a large bowl, whisk together flour, paprika, cayenne pepper, cumin, thyme, oregano, salt, and pepper. In a separate medium bowl, whisk eggs, milk, and water.
Step 6: Place the onion cut-side up in a clean bowl and pour the flour mixture over it. Use a large spoon to coat the onion thoroughly, especially between petals. Turn the onion over and gently pat off excess flour. Reserve the flour mixture.
Step 7: Dip the onion into the egg mixture, coating evenly. Let excess drip off.
Step 8: Transfer the onion back into the reserved flour mixture and coat again, tapping off extra flour gently.
Step 9: Place the coated onion in the refrigerator while you preheat the air fryer.
Step 10: Preheat the air fryer to 350ºF for 10 minutes.
Step 11: Remove the onion from the refrigerator and spray liberally with vegetable oil using the spray bottle.
Step 12: Create a sling from a sheet of aluminum foil, then transfer the onion cut-side up into the air fryer basket using the sling.
Step 13: Cook for 25 minutes, spraying the onion 2-3 times with oil as it cooks. If any flour spots remain visible, spray those areas as well.
Step 14: After cooking, carefully remove the onion with the sling and season with salt and pepper to taste.
Step 15: Serve immediately with your favorite dipping sauce, such as a creamy blooming onion dip.

Tips & Variations

Use a large sweet onion for the best texture and sweetness.
Be gentle when separating the petals to avoid breaking them.
For extra flavor, add garlic powder or smoked paprika to the flour mixture.
If you don’t have an air fryer, you can deep fry the onion in hot oil until golden and crispy.
Serve with ranch dressing, spicy mayo, or blue cheese dip for a tasty contrast.

Storage

Store any leftover blooming onion in an airtight container in the refrigerator for up to 2 days. Reheat in the air fryer at 350ºF for 3-5 minutes to restore crispiness. Avoid microwaving as it may make the coating soggy.

How to Serve

A large white plate holds one large blooming onion, with multiple orange-brown crispy fried layers fanning outward and upward, showing their textured, crunchy coating. The layers are split into thick, curved segments piled close together in a circular shape. The plate sits on a wooden board with a bowl of light pink creamy dipping sauce topped with a piece of fried onion on the side. A striped blue and white cloth is nearby on a white marbled surface.

FAQs

Can I use other types of onions for this recipe?

While sweet onions are preferred for their mild flavor and size, you can use yellow onions if needed. Avoid small onions as they won’t bloom as well.

What is a blooming onion dip?

Blooming onion dip is usually a creamy, tangy sauce made with mayonnaise, ketchup, horseradish, and spices. It pairs perfectly with the crispy onion petals for dipping.
