• 1 teaspoon paprika

• ½ teaspoon salt
  Balances and enhances all flavors.
• ½ teaspoon black pepper
  Adds mild heat and complexity.
• 1 large egg
  Helps bind the coating to the onions.

Tools & Equipment Needed

• Air fryer
• Mixing bowls (at least 2)
• Whisk
• Knife
• Cutting board
• Tongs or fork for dipping
• Wire rack (for cooling)
• Cooking spray

Optional:

• Baking sheet (to hold coated onions before frying)

Step-by-Step Instructions

1. Prepare the onions
   Peel the 2 large onions and slice them into thin rings, about ¼ inch thick. Separate the rings gently.
2. Soak in buttermilk
   Place the onion rings in a bowl and cover them with 1 cup buttermilk. Let them soak for at least 30 minutes. This step softens the onions and helps the coating adhere better.
3. Prepare the coating
   In a separate bowl, whisk together:
   • 1 cup all-purpose flour
   • 1 teaspoon garlic powder
   • 1 teaspoon paprika
   • ½ teaspoon salt
   • ½ teaspoon black pepper
   Mix until evenly combined.
4. Coat the onions
   Remove the onions from the buttermilk, allowing excess liquid to drip off. Dip each ring into the flour mixture, ensuring a full, even coating. Shake off any excess flour.
5. Preheat the air fryer
   Preheat your air fryer to 375°F (190°C) for about 5 minutes.
6. Arrange in the basket
   Spray the air fryer basket lightly with cooking spray. Place the coated onion rings in a single layer, making sure they don’t overlap. Spray the tops lightly with cooking spray.
7. Air fry
   Cook for 10–12 minutes, flipping halfway through, until the onions are golden brown and crispy.
8. Cool and serve
   Carefully remove the crispy onions and let them cool slightly on a wire rack. This helps maintain their crispiness. Serve warm.
