Crispy Onion Petals

Pro tips

• Separate onion layers carefully by hand to prevent tearing; larger petals fry more evenly than tiny bits.
• Spray oil lightly and evenly on both sides of coated petals—uneven coverage leads to soggy spots.
• Check for golden-brown color and crispness at the 8-minute mark; cooking past 10 minutes risks burning the panko.

Substitutions

• panko breadcrumbs → Italian seasoned breadcrumbs (adds herb flavor, slightly less crisp)
• olive oil spray → avocado oil spray (higher smoke point, neutral taste)
• all-purpose seasoning → garlic powder + paprika + salt (more control over flavor profile)

Storage & make-ahead

Store cooled onion petals in an airtight container for up to 2 days; reheat in the air fryer at 350°F for 3–4 minutes to restore crispness.

Can I use regular breadcrumbs instead of panko?

Yes, but panko creates a crispier, airier texture. Regular breadcrumbs will compact more and produce a denser coating.

How do I prevent the onion petals from sticking together?

Separate the onion layers completely, coat them individually, and arrange them in a single layer without overlapping during cooking.

What temperature and time should I use in an air fryer?

Air fry at 400°F (200°C) for 8–10 minutes, shaking the basket halfway through, until golden brown and crispy.

Can I make the dipping sauce ahead of time?

Yes, the mayo-ketchup-horseradish sauce keeps refrigerated for up to 5 days in an airtight container.
