  • 1/4 cup all-purpose flour

  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon paprika
  • Salt and pepper, to taste
  • Cooking spray or a small amount of oil

How to Make Air Fryer Crispy Onions

  1. Prepare the Onion: Peel and thinly slice the onion into rings or strips. Aim for uniform slices to ensure even cooking.
  2. Mix the Coating: In a bowl, combine the all-purpose flour, cornmeal, garlic powder, paprika, salt, and pepper to create your dry mixture.
  3. Coat the Onion: Toss the onion slices in the flour mixture until they are well coated, ensuring each piece is covered for maximum crunch.
  4. Preheat the Air Fryer: Preheat your air fryer to 300°F (150°C) to prepare for cooking.
  5. Prepare the Basket: Spray the air fryer basket with cooking spray or lightly oil it to prevent sticking.
  6. Cook the Onion: Place the coated onion slices in the basket in a single layer, working in batches as necessary to avoid overcrowding.
  7. Air Frying: Air fry the onions for 15–20 minutes, shaking or stirring halfway through, until they are golden brown and crispy. Look for a rich color and a crispy texture.
  8. Cool and Serve: Once done, carefully remove the onions and let them cool slightly before serving. Enjoy their crunchiness at your next meal!

Tips for Best Results

  • Use a mandoline slicer for perfectly uniform onion rings that cook evenly.
  • Don’t skip preheating the air fryer; it ensures the onions start cooking immediately, achieving better crispiness.
  • If you’re making a large batch, air fry in batches to avoid steaming the onions.
  • After cooking, let the crispy onions cool completely before storing to maintain their crunch.
  • For an extra flavor kick, experiment with additional spices like cayenne pepper, oregano, or cumin in your coating mixture.

Variations and Substitutions

If you’re looking to add some extra flavor, you can swap out the paprika for smoked paprika for a delicious smoky undertone. You might also consider using gluten-free flour if you need a gluten-free option, but remember it may slightly alter the final texture. For a spicy version, add a pinch of cayenne pepper to the dry mixture.
