Ingredients:
- 1 large onion – sweet or yellow onion works best
- 1 cup all-purpose flour
- 1 tablespoon paprika
- 1 teaspoon Italian seasoning
- 1 teaspoon kosher salt
- 1 teaspoon garlic powder
- 1 teaspoon chili powder (or 1/2–1 teaspoon cayenne for more heat)
- 1 cup water (plus extra tablespoon if needed)
- 1 cup Italian seasoned breadcrumbs
- Cooking spray or light oil mist for crisping
How to Make Bloomin’ Onion
-
Prepare an aluminum foil sling or a pair of tongs to remove the hot onion from the air fryer basket safely after cooking.
-
Peel the outer skin of the onion and trim off the top (the stem end). Place the onion cut side down on a cutting board to make slicing easier.
-
Slice from the top toward the root, leaving a small uncut circle in the center so the petals stay attached. Make 8–10 evenly spaced cuts through all layers without cutting through the root. Add more cuts if additional petals are desired.
-
Place the sliced onion in ice-cold water for about 1 hour. Soaking helps the layers separate and makes it easier to open the petals for coating.
-
In a medium bowl, combine the flour, paprika, Italian seasoning, salt, garlic powder, and chili powder. Gradually whisk in 1 cup water until a smooth batter forms; add a tablespoon of water or a little extra flour if the consistency needs adjusting.
-
Drain the onion and pat dry lightly. Gently open the petals without tearing the root, spreading them as wide as possible. Place the onion in a deep bowl and either dip it into the batter or spoon the batter over the petals so they’re evenly coated.
-
Let excess batter drip off briefly, then transfer the onion to a clean bowl and sprinkle breadcrumbs over the petals to coat thoroughly. Press the crumbs gently so they adhere to the batter.
-
Lightly mist the onion petals with cooking spray for extra crisping. Place the onion cut-side down in the air fryer basket. Air fry at 380ºF (193ºC) for 15–20 minutes, or until the coating is golden brown and crisp. Cooking times will vary slightly by air fryer model and size—check at 15 minutes and adjust as needed.
This recipe was tested in a Cosori 5.8 qt. air fryer; other models may require 1–2 minutes more or less. After cooking, use an aluminum foil sling or tongs to lift the onion from the basket. Let it rest for a couple of minutes before serving so the coating firms up and the onion is easier to handle.
FAQ
Store leftover slices in an airtight container in the refrigerator for 3–4 days. Reheat in the air fryer at a lower temperature for a few minutes to restore crispness.
Use a large sweet or yellow onion. Sweet onions are milder and slightly sweeter, while yellow onions offer a stronger flavor. Choose a firm, heavy onion with even layers for best results.
Classic pairings include spicy ranch, regular ranch, sour cream-based dips, or a tangy Worcestershire and hot sauce blend. Choose a creamy dip to complement the crunchy coating.

Tips and Serving Suggestions
- Soak the onion long enough that the petals separate easily; this makes coating much simpler.
- Don’t over-slice the center—leave enough root to hold the petals together while cooking.
- For extra crunch, give the coated onion a light spray of oil midway through cooking.
- Serve with a cool, creamy dip to balance the spice and saltiness of the coating.
- To make party prep easier, assemble the onion and refrigerate briefly before air frying, then cook just before guests arrive.
