Blooming Onion in an Air Fryer

Ingredients

• 1 large Yellow Onion (Top inch removed, peeled, cut into 16 petals)
• 2 large Eggs (Beaten)
• 0.5 cup Milk (Whole or 2% works best)
• 1 cup All-Purpose Flour (For coating)
• 1 tsp Salt (Regular table salt)
• 0.25 tsp Cayenne Pepper (Adds heat; optional)
• 1 tsp Paprika (Smoked or sweet)
• 0.5 tsp Black Pepper (Freshly ground)
• 0.5 tsp Dried Oregano (Optional herb)
• 0.5 tsp Dried Thyme (Optional herb)
• 0.5 tsp Ground Cumin (Optional spice)
• 2 tbsp Cooking Spray (For spritzing before air‑frying)

Instructions

1. Trim and Peel the Onion

   Slice off the top inch of the onion, peel away the papery skin, and keep the root end intact.

   Time: PT5M

2. Create the Blooming Petals

   Make a cut about three‑quarters of the way down from the top, turn the onion 90°, cut again, and repeat until you have 16 evenly spaced sections.

   Time: PT5M

3. Separate the Layers

   Gently pull apart each petal and place all the pieces in a large bowl.

   Time: PT2M

4. Prepare the Egg‑Milk Bath

   In a separate bowl, whisk together the eggs and milk until fully combined.

   Time: PT3M

5. Prepare the Seasoned Flour

   In another bowl, combine flour, salt, cayenne, paprika, black pepper, oregano, thyme, and cumin. Mix well.

   Time: PT3M

6. Double‑Coat the Onion Petals

   Working one petal at a time, dip it into the egg‑milk mixture, then into the seasoned flour, back into the egg‑milk, and again into the flour. Shake off any excess flour before moving to the next petal.

   Time: PT7M

7. Spritz with Oil

   Place the coated onion on a plate and give it a generous spritz of cooking spray.

   Time: PT1M

8. Preheat the Air Fryer

   Set the air fryer to 375°F and let it preheat.

   Time: PT5M

   Temperature: 375°F

9. Air‑Fry the Blooming Onion

   Place the onion in the air‑fryer basket, spray a little more oil on top, and cook for 25‑30 minutes, shaking the basket halfway through.

   Time: PT30M

   Temperature: 375°F

10. Rest and Serve

    Remove the onion, let it rest for 2 minutes, then serve immediately with your favorite dipping sauce.

    Time: PT2M

Critical Steps — Do Not Skip

• Double‑coating each petal (egg‑milk, flour, repeat) to ensure crispness
• Spritzing with oil before air‑frying
• Cooking at the correct temperature and time for a golden crust

Chef Tips from the Video

• Use a sweet Vidalia onion for a milder, sweeter flavor.
• Add a pinch of garlic powder to the flour mixture for extra depth.
• Serve with a side of ranch dressing or a spicy aioli for dipping.

Troubleshooting

Storage

Refrigerator: Store leftovers in an airtight container for up to 2 days; reheat in the air fryer for 3‑4 minutes.

Freezer: Not recommended – texture becomes soggy after freezing.

Room temperature: Best served immediately; can sit out for up to 1 hour before losing crispness.

Make-Ahead Tips

• Prepare the onion and both batters up to step 6, then cover and refrigerate for up to 4 hours before cooking.
• Preheat the air fryer while you are coating the onion to save time.
