Ingredients You’ll Need

• 2 small sweet onions (peeled, with the root still attached)
• 1/2 cup all-purpose flour
• 1/2 teaspoon paprika
• 1/2 teaspoon garlic powder
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1 large egg (let it come to room temperature)
• 1/4 cup milk (any kind works)
• Cooking spray or a light oil sprayer

Air Fryer Cooking Instructions

1. Preheat the air fryer to 375°F.
2. Peel onions and trim about 1/4 inch off the top, keeping the root intact.
3. Set each onion root-side down and make 4 vertical cuts toward the root, stopping about 1/2 inch from the bottom; gently fan out the petals.

4. Whisk together flour, paprika, garlic powder, salt, and pepper in a shallow bowl.

5. Whisk egg and milk together in a separate bowl until smooth.
6. Roll each onion in the flour mixture, working flour between the petals.
7. Dip the floured onion in the egg wash, letting excess drip off.

8. Return the onion to the flour mixture for a final coat.

9. Place coated onions root-side down in the air fryer basket, leaving at least 1 inch between them for air circulation.
10. Lightly spray each onion with cooking spray or oil.
11. Air fry at 375°F for about 10 minutes, pausing at 5 minutes to gently shake or turn the basket so the petals crisp evenly.

12. If the onions aren’t sufficiently browned after 10 minutes, air fry an additional 1–2 minutes while watching to avoid burning.

13. Carefully remove the onions from the air fryer.

    

Expert Tips for Best Crunch

• Choose onions that are similar in size: Aim for small sweet onions about the size of a baseball so they cook evenly.
• Don’t cut through the root: Leaving a little root intact keeps those petals together; cutting the root will cause them to fall apart.
• Always preheat your air fryer: This step stops steaming and helps get that crisp, golden crust.
• Shake or rotate partway through cooking: This helps the inner petals get nice and browned too.
• Spray oil lightly: Just a quick mist lets the coating brown without becoming soggy from too much oil.
• Serve right away: These are best fresh from the fryer because they lose their crunch as they cool.

Flavor Variations and Substitutions

• Add some heat: Mix in 1/4 to 1/2 teaspoon cayenne or chili powder into the flour for a spicy kick.
• Extra crunch: Swap half the flour for panko breadcrumbs to get an even crispier coating.
• Make it gluten-free: Use a 1:1 gluten-free flour blend instead of regular flour for those avoiding gluten.
• Dairy-free option: Grab your favorite plant-based milk and swap the egg for a flax egg (1 tbsp ground flaxseed mixed with 3 tbsp water), keeping in mind the texture might be a bit different.
• Tasty dips: Serve with Greek yogurt mixed with lemon and dill, spicy salsa, or a light ranch dressing for dipping.

Storage and Reheating Guide

If you happen to have leftovers (if that’s even a thing!), store them in an airtight container in the fridge for up to 2 days. To bring back the crispness, pop them into the air fryer at 375°F for 3–4 minutes before serving again. Skip the microwave — it makes them soggy, and nobody wants that. You can prep the onions (peeled and cut) ahead, but for the crispiest results, coat and cook just before serving.

Common Questions Answered

• Can I use larger onions? It’s best to stick with small sweet onions about the size of a baseball or tennis ball. Larger ones tend to cook unevenly in the air fryer.
• Can I bake these instead of air frying? Sure! Baking at 425°F on a rack over a sheet pan for around 20 minutes works, flipping halfway. Just know they won’t be quite as crispy as air-fried.
• What’s the best way to store leftovers? Keep them in an airtight container in the fridge for up to 2 days. Reheat in the air fryer at 375°F for a few minutes to get that crunch back.
• Can I freeze these? I don’t recommend freezing—they usually lose their texture and get soggy after thawing and reheating.
• What if my petals don’t open up well? Make sure you cut nearly all the way down to about half an inch from the root and fan the petals before coating. Also, preheating the air fryer helps them open and crisp nicely.
