Set your oven to 400°F (200°C). Line a large 12x17 inch rimmed baking sheet with parchment paper. The parchment is important to prevent sticking and helps the chips release easily once baked.

Sprinkle the shredded parmesan cheese evenly across the parchment-lined baking sheet, creating a thin and even layer that will become crispy as it bakes.
03 -
Place your onion ring slices on top of the cheese layer. Position them so they're not overlapping but are sitting right next to each other. This ensures they'll cook evenly and get crispy.
04 -
Brush the tops of the onion rings lightly with olive oil. Then sprinkle with salt, garlic powder, and paprika according to your taste preferences. The oil helps the seasonings stick and assists with browning.
05 -
Bake in your preheated oven for about 18 minutes, or until the cheese and onions have turned a beautiful golden brown color. Watch carefully near the end to prevent burning.
06 -
Once baked, remove from the oven and let the sheet cool for 5-10 minutes. This cooling time is crucial as it allows the cheese to set firm, making it easier to break apart into chips. Then simply break into pieces and enjoy!
