Ingredients
Onion
- 1 large sweet onion
Breading
- 1 cup all-purpose flour
- 1 tsp paprika
- 1 tsp garlic powder
- 1/2 tsp salt
- 1/2 tsp black pepper
- 1/2 tsp cayenne pepper (optional)
Wet Ingredients
- 2 eggs
- 1/4 cup milk
Others
- Cooking spray
Instructions
- Prepare the Onion: Slice off the top of the large sweet onion and peel it, leaving the root end intact to hold the petals together. Carefully separate the onion into petal shapes to create the ‘blooming’ appearance.
- Mix Dry Ingredients: In a medium bowl, combine the all-purpose flour, paprika, garlic powder, salt, black pepper, and optional cayenne pepper. Stir well to mix the seasoning evenly.
- Prepare Wet Mixture: In a separate bowl, whisk together the eggs and milk until smooth and fully blended.
- Coat the Onion: First, dredge the blooming onion carefully in the seasoned flour mixture, ensuring all petals are coated. Next, dip it into the egg and milk mixture, allowing excess liquid to drip off. Finally, coat the onion again thoroughly with the flour mixture for a double layer of breading.
- Preheat and Spray: Preheat your air fryer to 375°F (190°C). Generously spray the entire coated onion with cooking spray to help achieve a crispy and golden exterior during air frying.
- Air Fry the Onion: Place the prepared onion gently into the air fryer basket. Cook at 375°F for 12-15 minutes, or until the onion is crispy and golden brown, checking halfway through and spraying with cooking spray if needed to enhance crispiness.
- Serve: Once cooked, carefully remove the blooming onion from the air fryer. Serve hot with your favorite dipping sauce such as ranch, spicy mayo, or BBQ sauce.
Notes
- Leave the root end of the onion intact to keep the petals together during coating and cooking.
- Use cooking spray generously to help achieve a crispy texture without deep frying.
- Cayenne pepper is optional, adjust based on spice preference.
- For even cooking, check the onion halfway through and spray again if it looks dry.
- Air fryer models may vary; cooking time might need slight adjustments.
