Chef Tips from the Video
- Freshly grated Parmesan gives the best flavor and texture.
- Yellow onions provide natural sweetness; white onions can be used for a sharper bite.
- A light brush of oil prevents the cheese from sticking to the parchment.
- For extra crunch, sprinkle a tiny pinch of sea salt just before serving.
Troubleshooting
Onion rings break during slicing.
Use the mandolin guard and slice slowly; if a ring breaks, set it aside and use whole rings for the main layer.
Cheese does not crisp, remains soft.
Make sure the cheese layer is thin (about 1/8 inch) and bake at full 400°F. If needed, extend baking by 2‑3 minutes.
Edges are burnt while centers are undercooked.
Rotate the baking sheet halfway through baking and move it to a middle rack if the back of the oven runs hot.
Storage
Refrigerator: Store cooled chips in an airtight container for up to 3 days. Re‑crisp in a 350°F oven for 5 minutes before serving.
Freezer: Not recommended; the cheese may become soggy after thawing.
Room temperature: Can be kept in a sealed bag for up to 1 day, but will lose crispness.
Make-Ahead Tips
- Prepare the chips up to step 7, then refrigerate the assembled sheet for up to 12 hours. Bake when ready.
- Re‑heat leftovers in a preheated 350°F oven for 5‑7 minutes to restore crispness.
