Each ingredient is carefully chosen to add layers of flavor, crunch, and that signature golden finish. Here’s everything you need, along with tips to guarantee blooming onion perfection.

• Sweet Onion (1 large, like Vidalia): The natural sweetness balances the bold seasoning and the petals separate beautifully when cut just right.
• All-Purpose Flour (¾ cup): Flour forms the backbone of your crispy crust and ensures every petal gets that golden crunch.

• Onion Powder (½ tsp): Intensifies the onion flavor, working in tandem with the fresh onion itself.
• Dried Oregano (½ tsp): Adds a subtle herby aroma for depth.
• Salt (½ tsp for coating, ¼ tsp for sauce): Seasoning is key! It sharpens flavors throughout.
• Black Pepper (¼ tsp): Adds a gentle kick without overpowering the onion.
• Cayenne Pepper (¼ tsp, optional): Gives a pleasant heat for those who like a little spice.
• Eggs (2 large): Their protein ensures the coating adheres for extra crunch.
• Milk (¼ cup): Loosens the egg mixture so it soaks into every petal.
• Mayonnaise (½ cup): The creamy base for your tangy, classic dipping sauce.
• Ketchup (2 tbsp): Lends a little sweetness and color to the dip.
• Prepared Horseradish (1 tsp): Brings zippy, peppery flavor to wake up your taste buds.
• Paprika (½ tsp, for sauce): Doubles down on color and flavor in the dip.
• Garlic Powder (¼ tsp, for sauce): Ties the dipping sauce together with a savory thread.
• Dash of Hot Sauce (optional): Add a punch if you like your dip with attitude.

How to Make air fryer blooming onion

Step 1: Cut the Onion into a Bloom

Grab your sweet onion and peel it, then slice about half an inch off the pointed end, making sure you leave the root end untouched—that’s what holds everything together. Place it root-side down, and carefully make four evenly spaced downward cuts starting about half an inch from the root. Give your onion more petals by making two or three smaller cuts between each major section. Finally, flip the onion over and gently separate the layers. It’s a bit like opening a flower; go slow, and the result is so rewarding!

Step 2: Prepare the Coating

Mix up a bowl of flour, cornstarch, and all those delicious seasonings (paprika, garlic powder, onion powder, oregano, salt, pepper, and optional cayenne). In a second bowl, whisk together the eggs and milk; this combination makes the magic “glue” that holds the crispy coating on every petal. Having your coatings set up assembly-line style will make the process a breeze.

Step 3: Dredge the Onion

Before you start, turn the onion upside down and gently shake off excess moisture for the best crunch. Dip the whole onion into your egg mixture, spooning it between petals so everything gets coated. Then transfer the onion into the flour mixture, flipping and sprinkling to ensure every nook and cranny is covered. For serious crunch fans, repeat the egg and flour dip one more time! This double-dip method is restaurant secret for ultra-crispy deliciousness.

Step 4: Air Fry the Onion

Preheat your air fryer to 350°F for at least five minutes—this ensures consistent results every time. Spray the basket lightly with oil to keep anything from sticking. Set your onion cut-side up, then give it a mist with cooking spray or oil all over to encourage beautiful browning. Air fry for 15 to 20 minutes, peeking in every five minutes to check for that irresistible golden color. Once perfect, carefully use tongs or a spatula to remove your blooming masterpiece.

Step 5: Make the Dipping Sauce

While the onion gets crispy in the air fryer, stir together mayonnaise, ketchup, horseradish, paprika, garlic powder, salt, and a dash of hot sauce for a classic, zesty dip. The flavors meld as it chills—keep it covered in the fridge until serving time. You’ll want plenty for dunking!

Garnishes

For a finishing touch, garnish your air fryer blooming onion with a sprinkle of chopped fresh parsley, a dash of extra smoked paprika, or even a few sliced green onions. These touches brighten the dish and make the colors pop, turning your appetizer into a true showstopper.

Side Dishes

Pair your blooming onion with cool, crisp salads, crunchy celery sticks, or roasted vegetables for delightful contrast. If you’re serving a crowd, it goes perfectly with sliders, barbecue, or even classic game day fare like wings—anything that makes you want to dip back in for that tangy sauce!

Creative Ways to Present

Don’t just stop at the classic serve—get playful with your presentation! Try placing the air fryer blooming onion on a rustic wooden board surrounded by colorful veggies, or serve individual petals as a fun finger food at parties. For smaller gatherings, pair each onion with a mini ramekin of dip so everyone gets their own.

Make Ahead and Storage

Storing Leftovers

If you find yourself with extra air fryer blooming onion (a rare occurrence!), place the leftovers in an airtight container and refrigerate for up to two days. The coating may soften over time, but the flavors only deepen.

Freezing

Freezing is possible, though best for short periods. Wrap the cooled onion tightly in plastic wrap and store it in a freezer-safe bag or container for up to one month. Thaw overnight in the refrigerator before reheating so the texture stays as crisp as possible.

Reheating

To recapture the crispiness, reheat your blooming onion in the air fryer at 350°F for five to seven minutes. Avoid microwaving, as this tends to make the petals soggy—air frying brings back that golden, crunchy exterior you love!

FAQs

Can I make this air fryer blooming onion gluten free?

Absolutely! Just substitute your favorite gluten free all-purpose flour blend in place of regular flour and double-check that your cornstarch is gluten free. The results are just as crispy and delicious.

What’s the best type of onion to use?

Sweet onions like Vidalia are perfect for air fryer blooming onion because they’re mild and have a natural sweetness that balances out the salty, spicy coating. Avoid overly pungent onions, as they can overpower the dip and seasonings.

Can I use a different dipping sauce?

Definitely! Ranch, honey mustard, or even a spicy sriracha mayo all make fantastic substitutes for the classic horseradish dip—feel free to get creative with your favorites.

Is it necessary to double coat the onion?

For the crispiest results, the double dredge is highly recommended. It envelops every petal in a thick, crunchy layer that stands up to dipping and stays crisp longer. If you’re in a rush, you can skip it, but you’ll notice the difference!

How do I keep my air fryer blooming onion from falling apart?

The key is to leave the root end intact while cutting and handling the onion gently when separating petals and coating. Use tongs or a spatula to transfer the onion so those gorgeous petals stay connected all the way to the plate.

Final Thoughts

Give this air fryer blooming onion a whirl—it’s shockingly easy, endlessly fun, and guaranteed to steal the show at your next gathering. Once you taste that golden crunch and zesty dip, you might just find yourself whipping up this masterpiece again and again!
