Step-by-Step Instructions
Blooming Onion Sauce:
- In a bowl, combine mayonnaise, sour cream, ketchup, horseradish, paprika, salt, garlic powder, dried oregano, black pepper, and cayenne pepper. Mix well and cover. Refrigerate until needed.
Blooming Onion:
- Cut the top off the onion, about ½ inch down, and peel away the outer skin.
- Place the onion cut-side down. Making a downward cut from about ½ inch above the root, create four evenly spaced cuts around the onion.
- Slice three additional cuts between each of the first cuts for a total of 16 petals.
- Flip the onion over and allow it to sit for 5 minutes to relax the petals. Gently separate them with your fingers.
- In a large bowl, whisk together flour, paprika, cayenne, cumin, thyme, and oregano.
- In another bowl, combine eggs, milk, and 1 cup water. Whisk until blended.
- Place the onion cut-side up in a clean bowl and pour the flour mixture over it, ensuring all petals are coated. Turn the onion over and gently pat off excess flour. Reserve remaining flour.
- Dip the onion into the egg mixture, letting excess drip off, then return to the flour mixture and repeat the process for better coating.
- Refrigerate the coated onion while preheating the air fryer to 350°F for 10 minutes.
- When ready, spray the onion generously with cooking oil.
- Create a sling with a piece of aluminum foil and place the onion cut side up in the fryer basket.
- Cook for 25 minutes, spraying with oil 2 to 3 times throughout the cooking.
- Carefully lift the onion from the fryer using the foil sling and season with salt and pepper.
- Serve hot with the blooming onion dip. Enjoy!
Best Ways to Enjoy It
Serving this air fryer blooming onion can be an experience in itself. Here are some creative ideas:
- Presentation: Place the blooming onion artfully in the center of a large platter surrounded by your blooming onion sauce for dipping.
- Pair with Drinks: Serve alongside iced tea, soda, or a light beer—perfect complements to balance out its crunchiness.
- Add Sides: Consider pairing with carrot sticks, celery, or even a fresh salad to add a pop of color and freshness to your table.
Keeping Leftovers Fresh
If you happen to have any blooming onion left after serving (which is rare!), here’s how to store it:
- Fridge: Keep leftovers in an airtight container in the refrigerator for up to 3 days.
- Reheating: Reheat in the air fryer for a few minutes at 350°F to regain some of that initial crispiness. Avoid the microwave as it can turn the onion soggy.
- Freezing: Freezing is not recommended, as the texture tends to suffer upon thawing.
Helpful Cooking Tips
To ensure your blooming onion turns out perfectly every time, consider these pro tips:
- Sweet Onion Selection: Opt for a large sweet onion, like a Vidalia or Walla Walla, as they’re less pungent and notably sweeter.
- Flouring Technique: Don’t rush the flouring process; make sure to get flour between the petals for maximum flavor and crunch.
- Air Fryer Variability: Cooking times can vary based on the air fryer model, so adjust the cooking duration as needed if it’s not the desired color or crispness.
Creative Twists
Looking to switch things up? Here are some variations you might find scrumptious:
- Spicy Sriracha Sauce: Replace the horseradish in the dipping sauce with sriracha for a spicy kick.
- Cheesy Blooming Onion: Add grated Parmesan or cheddar cheese to the flour mixture for a cheesy touch.
- Herb Infusion: Mix fresh herbs like parsley or cilantro into the batter for a fresher taste.
- Gluten-Free Option: Use almond flour or a gluten-free blend in place of all-purpose flour for suitable dietary adjustments.
