The cooking process explained
Creating a Crispy Air Fryer Blooming Onion involves a few straightforward steps that come together beautifully. You’ll start by prepping your onion, which involves cutting it just right to create those signature petals. Toss the onion in a seasoned flour blend, dip it into an egg wash to help the breadcrumbs stick, and then coat it in a crispy breadcrumb mixture. The air fryer does the magic, transforming this coated onion into a deep-fried-looking treat with far less fat.
Ingredients
- 1 large onion (Use a sweeter onion like a Vidalia for a milder flavor.)
- 1 cup all-purpose flour (Can substitute with gluten-free flour.)
- 1 cup breadcrumbs (Try Italian seasoned or panko for extra crunch.)
- 1 tablespoon paprika
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 2 large eggs
- 1/2 cup milk
- Cooking spray (For spraying the coated onion.)
Directions
- Start by carefully slicing the onion from the top downwards, avoiding cutting all the way through to leave the base intact. Aim for about 12-16 evenly spaced cuts.
- In a bowl, mix the flour, paprika, garlic powder, onion powder, salt, and black pepper.
- In another bowl, whisk the eggs and milk together until well combined.
- Place the breadcrumbs in a separate dish.
- First, dunk the onion into the flour mixture, making sure to coat all the petals well.
- Next, dip the coated onion into the egg mixture, allowing any excess to drip off.
- Finally, coat the onion in breadcrumbs for that perfect crunch.
- Spray the air fryer basket lightly with cooking spray, and place the onion inside.
- Spray the top of the onion with a bit more cooking spray.
- Cook in the air fryer at 350°F (175°C) for about 15-20 minutes, or until golden brown and crispy. Turn halfway for even cooking.
- Carefully remove and let it cool slightly before serving.
Best ways to enjoy it
This Crispy Air Fryer Blooming Onion pairs beautifully with a variety of dips. A classic choice is creamy ranch dressing or zesty homemade remoulade. If you’re feeling adventurous, serve it with a spicy sriracha mayo or a tangy blue cheese dip. As for side dishes, consider serving it alongside fresh salads, crispy fries, or even savory stuffed mushrooms for a complete spread that will impress your guests.
Keeping leftovers fresh
Storing your blooming onion is straightforward. If you have leftovers, place them in an airtight container in the refrigerator for up to 3 days. Reheating is best done in the air fryer for about 5-7 minutes at 350°F (175°C) to regain that beloved crispness. If you intend to keep them longer, freezing is an option. Flash freeze the cooked onion on a baking sheet before transferring to a freezer bag to ensure they don’t stick together.
Helpful cooking tips
To make the most of your blooming onion, be mindful of the onion’s preparation. Use a very sharp knife to make clean cuts without squashing the onion. If you’d like an even bolder flavor, consider adding additional spices or herbs to the breadcrumb mixture. For an extra crispy finish, you can re-dip the onion in the egg wash and breadcrumbs for a double layer before air frying.
Creative twists
Looking to switch things up? How about adding some grated cheese to the breadcrumb mix for a cheesy bloom? You could also experiment with different flavored breadcrumbs, like using seasoned breadcrumbs or adding spices like cayenne pepper or Italian seasoning for a zesty kick. If you’re vegan or gluten-free, don’t hesitate to substitute with appropriate alternatives for a wholly inclusive dish!
