Ingredients
To make these crispy air fryer onion petals with a spicy dipping sauce, you’ll need the following ingredients:
- 1 large sweet onion (Vidalia or yellow)
- 60 g all-purpose flour
- 1 tsp garlic powder
- 1 tsp onion powder
- 0.5 tsp smoked paprika
- 0.25 tsp cayenne pepper (optional for extra heat)
- 0.5 tsp salt
- 0.25 tsp black pepper
- 1 large egg
- 120 ml milk (any kind)
- 90 g Panko breadcrumbs
- Olive oil spray or neutral oil in mister
- 120 g mayonnaise
- 30 g sour cream or Greek yogurt
- 15 g ketchup
- 1 tbsp prepared horseradish
- 0.5 tsp smoked paprika (for the sauce)
- 0.25 tsp Worcestershire sauce
Feel free to use Greek yogurt as a healthier option for the sauce, or swap the sour cream based on your preference.
Step-by-step instructions
- Start by peeling and trimming the onion. Cut it in half, and then slice each half into 1/2-inch wedges. Carefully separate the wedges into petals, discarding the smaller inner layers.
- Set up your dredging station with three bowls:
- Bowl 1: Mix the flour, garlic powder, onion powder, smoked paprika, cayenne pepper, salt, and black pepper.
- Bowl 2: Combine the egg and milk.
- Bowl 3: Pour in the Panko breadcrumbs.
- Take each onion petal and coat it in the flour mixture, dip it into the egg mixture, and then coat it with the Panko breadcrumbs. Repeat this until all the petals are evenly coated.
- Preheat your air fryer to 375°F (190°C). Arrange the petals in a single layer in the basket, taking care not to overcrowd them.
- Generously spray the coated petals with olive oil spray to ensure crispiness. Air fry for about 5 minutes, then flip the petals, spray again, and continue cooking for another 5-10 minutes until they are golden brown and crispy.
- While the petals are cooking, whisk together the mayonnaise, sour cream, ketchup, horseradish, smoked paprika, and Worcestershire sauce for the dipping sauce. Chill until serving.
- Once cooked, transfer the crispy onion petals to a platter and serve immediately alongside the chilled dipping sauce.
Best ways to enjoy it
These crispy onion petals are versatile! They can serve as a fantastic appetizer, a party snack, or even a side dish for your favorite burger. To enhance the presentation, consider garnishing with fresh herbs or serve them on a colorful platter. Pair them with a refreshing beverage, like a tangy lemonade, to balance the heat from the dipping sauce. Enjoy them fresh out of the air fryer for the best texture.
How to store
If you find yourself with leftovers (though that’s rare!), you can store them in an airtight container in the refrigerator for up to 3 days. To reheat, pop them back into the air fryer at 350°F (175°C) for about 5 minutes to restore their crispiness. Freezing is not recommended, as the texture may suffer when thawed.
Helpful cooking tips
- For an extra flavor punch, consider adding Parmesan cheese to the Panko breadcrumbs.
- If you prefer a less spicy dipping sauce, adjust the horseradish to taste, or even replace it with a dollop of sweet chili sauce for a different kick.
- Feel free to experiment with flavored oils for an interesting twist on the coating!

There are endless variations you can try to customize this recipe to your tastes! Here are a few ideas:
- Swap the sweet onion for a white or red onion for a different flavor profile.
- Add spices like Italian seasoning or smoked garlic to the flour mixture for an exciting flavor boost.
- Make it a complete meal by serving the onion petals with grilled chicken tenders or veggie sticks for a fun platter.
