# Expert Tips:
01 -
- Everything cooks in one dish so cleanup is practically nonexistent
- The combination of melted cheese and tender vegetables feels like comfort food without being too heavy
02 -
- Dont skip the resting time or youll end up with a delicious mess on every plate
- The zucchini releases water as it cooks so if your tomatoes were extra juicy you might need to bake it 5 minutes longer
03 -
- Salt your zucchini slices and let them drain for 15 minutes before layering if you want an even firmer texture
- Run the dish under the broiler for 2 minutes at the end if you want extra crispy breadcrumb topping
