Ingredients
  

Essential Ingredients
  • 2 large onions Choose sweet or yellow onions for a mild, slightly sweet flavor.
  • 1 cup grated Parmesan cheese Freshly grated is best for texture and flavor.
  • 1 teaspoon garlic powder Adds savory depth without extra moisture.
  • 1 teaspoon paprika For color and a mild smoky note.
  • to taste salt and pepper Simple seasoning to enhance the onion and cheese.
  • as needed olive oil spray A light mist helps the Parmesan brown and crisp without deep frying.
Optional Add-Ons
  • 1/2–1 teaspoon onion powder For extra onion intensity in the crust.
  • crushed red pepper flakes If you like a little heat.
  • 1/2 teaspoon dried herbs (oregano, thyme, or Italian seasoning) Add for a herb-forward flavor.
  • freshly chopped parsley or chives Sprinkle after baking for freshness and color.
  • a pinch lemon zest Brightens the flavor when serving.
  • 1 small bowl Greek yogurt mixed with lemon and herbs For a lighter dipping sauce alternative.

Method
 

Preparation
  1. Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or a non-stick baking mat.
  2. Peel the onions and cut off the ends, then slice them into thick rings, about 1/2 inch thick.
  3. In a bowl, mix the grated Parmesan, garlic powder, paprika, salt, and pepper. Stir in any optional add-ons if using.
  4. Lightly spray a baking sheet with olive oil or lay down parchment paper to prevent sticking.
Coating
  1. Press each onion ring into the Parmesan mixture, ensuring it is well coated on all sides. Arrange in a single layer on the baking sheet.
  2. Spray the tops of the rings lightly with olive oil and sprinkle with additional salt and pepper if desired.
Baking
  1. Bake the onion rings in the preheated oven for 15-20 minutes, checking around 12-15 minutes. For extra crispiness, turn on the broiler for 1-2 minutes at the end.
  2. Let the rings cool for a minute or two on the pan before serving.

Notes

Don't overcrowd the baking sheet; use two sheets if necessary. A hot oven locks in sweetness and helps the crust crisp without needing much oil.
