Expert Tips
🔹 Use Small Onions – They crisp better than large ones.
🔹 Slice Thinly – Mandolin or sharp knife ensures crispiness.
🔹 Prevent Burning – Cheese turns bitter if overbaked. Check early!
🔹 No Oil Spray? Brush lightly with olive or avocado oil.
Storage & Reheating
- Best Fresh – Enjoy immediately for maximum crunch.
- Leftovers – Store in an airtight container 1–2 days (re-crisp in oven/air fryer).
- Freezing Not Recommended – Cheese loses crispiness.
