Ingredients for Air Fryer Blooming Onion
Here’s what you’ll need to make this delicious Air Fryer Blooming Onion:
1 large sweet onion – A Vidalia or another sweet onion for the best flavor and tenderness.
2 ½ cups all-purpose flour – This is the key to creating that delicious, crunchy coating.
1 tablespoon paprika – Adds a sweet and smoky flavor that enhances the onion.
1 teaspoon cayenne pepper – For a kick! Adjust based on your preference for spice.
½ teaspoon ground cumin – Gives an earthy note that balances the sweetness of the onion.
½ teaspoon dried thyme – A touch of herby flavor that rounds out the dish nicely.
½ teaspoon dried oregano – Complements the other spices and brings a savory element to the mix.
2 large eggs – Helps the flour adhere to the onion for that perfect crispiness.
1 cup milk – Goes into the egg wash for extra moisture and richness.
Salt and pepper to taste – Essentials that elevate the flavors.
Oil for frying – Spray or drizzle to ensure that your onion comes out crispy without the guilt.
¼ cup mayonnaise – Forms the base of a rich dipping sauce.
¼ cup sour cream – Adds creaminess and tang to the sauce.
2 teaspoons ketchup – A sweet touch that complements the other flavors.
1 tablespoon horseradish – For zesty heat; adjust to your taste.
¼ teaspoon paprika – Just a pinch to enhance the sauce’s flavor.
¼ teaspoon salt – Balance out the other components in the sauce.
⅛ teaspoon garlic powder – For a hint of garlicky goodness.

How to Make Air Fryer Blooming Onion
Follow these simple steps to prepare this delicious Air Fryer Blooming Onion:
Step 1: Prepare the Dipping Sauce
In a medium bowl, combine the mayonnaise, sour cream, ketchup, horseradish, paprika, salt, garlic powder, oregano, black pepper, and cayenne pepper. Mix until smooth, then cover and refrigerate to let the flavors meld together.
Step 2: Cut the Onion
Grab that large sweet onion! Cut off ½ inch from the top, then carefully peel off the first layer of skin. With your onion cut-side down, make four evenly spaced downward cuts around the onion, about ½ inch deep.
Step 3: Relax the Petals
Turn your onion over and let it sit for about 5 minutes. This step is crucial as it helps the petals relax. Use your fingers to gently separate them for that perfect blooming effect.
Step 4: Flour the Onion
In a large bowl, whisk together the flour, paprika, cayenne, cumin, thyme, and oregano. Place the onion cut-side up in another bowl and pour half the flour mixture over it. Use a large spoon to ensure you coat all the petals, then flip it over, patting off any excess flour.
Step 5: Egg Wash Time
In a deep bowl, whisk together the eggs, milk, and 1 cup of water. Dip the coated onion into this egg mixture, allowing excess to drip off, and then return it to the reserved flour mixture for a second coating.
Step 6: Chill and Air Fry
Refrigerate the onion for 15 minutes to set the coating. Preheat your air fryer to 350°F for about 10 minutes. Once preheated, spray the onion with cooking oil and transfer it cut side up into the fryer basket (a sling made from aluminum foil makes this easier!).
Now, set the timer for 25 minutes, spraying it with cooking oil a couple of times during cooking. When it’s perfectly golden, carefully use that foil sling to remove the onion from the fryer. Finish with a sprinkle of salt and pepper.
Serve your stunning Air Fryer Blooming Onion with the zesty dipping sauce and prepare for awe and applause! This crispy delight will be a crowd-pleaser and a conversation starter, ensuring your culinary creativity shines bright. Enjoy every crispy, flavorful petal!
