- ½ teaspoon smoked paprika
- ½ teaspoon Italian herb seasoning
- ½ teaspoon salt
- ¼ teaspoon chili powder
- ¼ teaspoon turmeric
- ¼ teaspoon black pepper

- ½ cup milk
- 1 large egg
- 2 tablespoons melted butter

Step-by-Step Instructions
1. Prepare the Onion
Start by trimming about half an inch from the top of the onion while keeping the root end intact. Peel away the outer skin and place the onion root-side down on a cutting board.
Using a sharp knife, carefully make four evenly spaced cuts downward into the onion, stopping before you reach the root. Then cut between each section to create eight sections total. Be careful not to slice completely through the onion.
Turn the onion upright and gently separate the layers with your fingers to create the blooming effect. Allow the onion to sit for a few minutes so the petals naturally spread apart.
2. Make the Seasoned Flour Mixture
In a medium bowl, combine the flour, garlic powder, onion powder, paprika, Italian seasoning, salt, chili powder, turmeric, and black pepper.
Mix everything thoroughly so the spices are evenly distributed throughout the flour. This seasoned coating gives the onion its crispy texture and bold flavor.
3. Prepare the Wet Mixture
In a separate bowl, whisk together the milk, egg, and melted butter until smooth.
This mixture helps the coating stick to the onion and creates a crisp outer crust once air fried.
4. Coat the Onion
Place the onion in a large bowl or on a tray. Sprinkle the seasoned flour mixture over the onion, making sure to get between all the petals. You can gently pull the layers apart with your fingers while coating to help the flour reach every section.
Shake off any excess flour.
Next, slowly pour the wet mixture over the onion. Rotate the onion slightly and separate the petals so the liquid coats the inside layers evenly.
After the wet coating, sprinkle the breadcrumbs or crispy coating mix over the onion for the final crunchy layer.
5. Chill Before Cooking
Place the coated onion in the refrigerator for about 10 minutes. Chilling helps the breading stick better during cooking and improves the final texture.
Meanwhile, preheat the air fryer to 300°F (150°C).
6. Air Fry the Onion
Once chilled, spray the onion generously with cooking oil spray. Be sure to coat any dry flour spots so they crisp properly during cooking.
Carefully place the onion into the air fryer basket. Depending on the size of your air fryer, you may place it on a small piece of foil for easier cleanup.
Air fry for 18–20 minutes, spraying lightly with oil once halfway through cooking. The onion should become golden brown and crispy around the edges.
If needed, cook for an additional 2–3 minutes for extra crispiness.
Serving Suggestions
Serve the blossom onion immediately while hot and crispy. It pairs wonderfully with a variety of dipping sauces such as:
- Garlic aioli
- Ranch dressing
- Spicy mayo
- Chipotle sauce
- Honey mustard
- Cheese sauce
You can also serve it alongside burgers, sandwiches, grilled chicken, or barbecue dishes.
Helpful Tips
Use a Large Onion
Large sweet onions work best because they create bigger petals and a more dramatic bloom shape.
Don’t Cut Through the Root
Keeping the root intact helps hold the onion together while cooking.
Spray Generously with Oil
Air fryers need a light coating of oil to achieve a crunchy, golden exterior.
Open the Petals Carefully
Separating the layers before coating helps the seasoning reach every bite.
Chill Before Air Frying
A short chill time helps prevent the coating from falling off during cooking.
Variations
Spicy Version
Add cayenne pepper or hot sauce to the wet mixture for extra heat.
Extra Crispy Style
Mix panko breadcrumbs into the final coating for additional crunch.
Herb & Parmesan
Add grated parmesan cheese and dried parsley to the breadcrumb mixture for a richer flavor.
Storage & Reheating
Store
Keep leftovers in an airtight container in the refrigerator for up to 2 days.
Reheat
Reheat in the air fryer at 350°F (175°C) for 3–5 minutes until crispy again. Avoid microwaving, as it may soften the coating.
