Equipment
- Baking Sheet
- Parchment Paper
- Mandoline slicer (optional)
Ingredients
- 2 cups finely shredded parmesan cheese divided
- 1 medium onion thinly sliced to 1/8 inch thickness and patted dry with paper towels
Instructions
Prep the oven and pan
- Preheat your oven to 350°F (177°C). Line a large baking sheet with parchment paper, ensuring it lies flat.
Create the bottom cheese layer
- Spread 1.5 cups of the shredded parmesan cheese evenly over the parchment paper in a very thin blanket, leaving no large gaps.
Arrange the onions
- Lay the thinly sliced, dry onion rings on top of the cheese in a single, tight layer. Do not overlap the slices.
Top with remaining cheese
- Sprinkle the remaining 1/2 cup of parmesan over the onion slices, covering them lightly but completely to form a second cheese layer.
First bake
- Slide the pan into the preheated oven and bake for 30 to 35 minutes. The cheese should be deeply golden and bubbly around the edges. Begin checking frequently after the 20-minute mark to prevent burning.
Cool to firm up
- Remove the pan from the oven but leave the oven on. Let the sheet rest on the pan for 5 to 10 minutes, allowing the cheese to cool slightly and firm up enough to be flipped.
Flip and finish baking
- Using a large spatula (or two), carefully flip the entire cheese and onion sheet over. Return the pan to the oven and bake for another 3 to 5 minutes to crisp up the underside until golden.
Cool and break into chips
- Take the pan out of the oven and let the chips cool for about 10 minutes until they are firm and crunchy. Snap the sheet into chip-sized pieces by hand and serve warm.
Notes
For the crispiest results, it's crucial to slice the onions very thinly (a mandoline works best) and pat them completely dry with paper towels to remove all excess moisture. Don't skip the final flip-and-bake step; this is the key to ensuring both sides are perfectly golden and crunchy. Store any leftovers in an airtight container and re-crisp in a hot oven or air fryer.
