Make ultra-crispy, thin onion ring chips seasoned with Parmesan and smoky spices. These are perfect for snacking or adding to party trays.

Ingredients

Scale
  • 1 large yellow onion, sliced 1/16-inch thick
  • 1/4 cup all-purpose flour
  • 1/4 cup grated Parmesan cheese
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon onion powder
  • 1/4 teaspoon salt
  • 1/8 teaspoon black pepper
  • Cooking spray

Instructions

  1. Preheat your oven to 275°F (135°C). Line baking sheets with parchment paper.
  2. Separate the onion slices into individual rings.
  3. In a medium bowl, whisk together the flour, Parmesan cheese, smoked paprika, garlic powder, onion powder, salt, and pepper.
  4. Add the onion rings to the bowl and toss gently to coat them evenly with the seasoning mixture.
  5. Arrange the coated onion rings in a single layer on the prepared baking sheets, ensuring they do not overlap.
  6. Lightly spray the tops of the onion rings with cooking spray.
  7. Bake for 45-60 minutes, or until the onion rings are golden brown and crisp. Flip them halfway through the baking time for even crisping.
  8. Let the onion chips cool completely on the baking sheets. They will become crispier as they cool.
  9. Serve immediately or store in an airtight container at room temperature.

Notes

  • For extra crispiness, you can use an air fryer. Arrange coated onion rings in a single layer in the air fryer basket and cook at 300°F (150°C) for 10-15 minutes, flipping halfway through, until golden and crisp.
  • These onion chips are best served within a few days of making them.
  • Serve with your favorite dipping sauces like ranch or a smoky aioli.
  • These can be made ahead and stored for easy party prep.
