Ingredients Equipment Method Notes

Ingredients
  

  • 2-3 medium white onions, sliced into 1/4-inch rounds
  • 2 cups freshly shredded Parmesan cheese
  • 2 tbsp extra virgin olive oil
  • salt, to taste
  • garlic powder, to taste
  • paprika, to taste
  • crushed red pepper flakes or dried herbs (optional)
  • fresh parsley or extra Parmesan for garnish (optional)

Equipment

  • baking sheet
  • parchment paper
  • knife
  • cutting board
  • pastry brush

Method
 

  1. Preheat oven to 400°F. Line a baking sheet with parchment paper.
  2. Spread the shredded Parmesan evenly over the parchment in a thin layer.
  3. Arrange onion slices in a single layer on top of the Parmesan, leaving space between each.
  4. Brush onion tops lightly with olive oil and season with salt, garlic powder, paprika, and optional spices.
  5. Bake for about 20 minutes until Parmesan is golden and onions are tender.
  6. Remove from oven and let cool on the baking sheet for 10 minutes to firm up.
  7. Lift from parchment, break into pieces, garnish if desired, and serve.

Notes

Use freshly shredded Parmesan for best results — pre-grated cheese will not crisp properly. Slice onions evenly to ensure consistent cooking. Allow chips to cool fully before serving to achieve maximum crispiness.
