Ingredients
To create your Air Fryer Blooming Onion, gather these ingredients:
For the Onion Bloom
- 1 large sweet onion
- 2 ½ cups all-purpose flour
- 1 tablespoon paprika
- 1 teaspoon cayenne pepper
- ½ teaspoon ground cumin
- ½ teaspoon dried thyme
- ½ teaspoon dried oregano
- 2 large eggs
- 1 cup milk
- 1 cup water
- Salt and pepper to taste
- Oil in a spray bottle
How to Make Air Fryer Blooming Onion
Step 1: Prepare the Onion
- Slice off 1/2 inch from the top of the onion and peel off its outer skin.
- Place the onion cut-side down on a cutting board. Start about 1/2 inch from the root, making downward cuts all the way through to create a blooming effect.
- Make four evenly spaced cuts around the onion and add three more cuts between each section until there are 16 evenly spaced cuts in total.
Step 2: Relax the Petals
- Turn the onion over gently and set aside for about 5 minutes. This allows the petals to relax, making them easier to separate later.
Step 3: Prepare Breading Mixture
- In a large bowl, whisk together flour, paprika, cayenne pepper, ground cumin, dried thyme, dried oregano, salt, and pepper.
- In another medium bowl, whisk together eggs, milk, and water until well combined.
Step 4: Coat the Onion
- Place the onion cut-side up in a clean bowl and pour some of the flour mixture over it. Use a spoon to coat all parts of the onion thoroughly.
- Turn over the onion to remove excess flour and reserve any remaining flour mixture.
- Dip the coated onion into the egg mixture next and let excess drip off before returning it to the reserved flour mixture for another coating.
Step 5: Chill Before Cooking
- Place coated onions in the refrigerator for about 10-15 minutes before cooking. This helps set the coating.
Step 6: Preheat Air Fryer
- Preheat your air fryer at 350°F (175°C) for about 10 minutes.
Step 7: Cook
- Remove chilled onions from refrigerator and spray generously with oil from your spray bottle.
- Use aluminum foil to create a sling and transfer cut-side up into your air fryer basket.
- Set timer for 25 minutes while occasionally spraying with oil during cooking (2-3 times).
Step 8: Finish & Serve
- After cooking time is complete, carefully remove using aluminum foil sling.
- Season with salt and pepper as desired before serving alongside your favorite dipping sauce.

How to Perfect Air Fryer Blooming Onion
Making the perfect Air Fryer Blooming Onion takes a bit of practice but can easily be mastered. Here are some tips to ensure your blooming onion turns out crispy and delicious every time.
- Bold Onion Selection: Choose a large, sweet onion for the best flavor and size. Sweet onions bloom beautifully in the air fryer.

- Thorough Coating: Ensure that you coat every petal well with flour mixture for maximum crunch. Don’t rush this step!
- Preheat Your Air Fryer: Preheating is crucial for achieving that desired golden brown finish. Always preheat before cooking.
- Spray Oil Generously: Don’t skimp on oil! Spraying generously helps achieve that crispy texture while cooking in the air fryer.
Best Side Dishes for Air Fryer Blooming Onion

- Coleslaw: A refreshing coleslaw offers a crunchy contrast and balances out the richness of the fried onion.
- Potato Wedges: Crispy potato wedges seasoned with herbs create a hearty side that pairs wonderfully with dipping sauces.
- Caprese Salad: Fresh mozzarella, tomatoes, and basil bring freshness to your plate, offsetting the heaviness of fried foods.

Common Mistakes to Avoid
Making an Air Fryer Blooming Onion can be simple, but there are a few common pitfalls to watch out for. Here are some mistakes to avoid:
- Skipping the soaking time: Not allowing the onion to relax after cutting can lead to less defined petals. Give it 5 minutes cut-side up for better blooming.
- Inadequate oil spraying: Failing to spray oil generously can result in dry spots. Make sure to coat the entire onion well before and during cooking.
- Overcrowding the air fryer: Placing multiple onions or other items in the basket can cause uneven cooking. Stick to one blooming onion per batch for optimal results.
- Ignoring flour distribution: Not fully coating the onion with flour can lead to parts not crisping up properly. Ensure every petal is covered with flour for that perfect crunch.
- Cooking at the wrong temperature: Cooking at too low a temperature can result in soggy petals. Preheat your air fryer to 350ºF before cooking for crispy results.
