Professional Notes
Storage
Store any leftovers in an airtight glass container in the refrigerator for up to 3 days. To maintain the crisp texture of the topping, reheat in the oven or toaster oven at 350°F (175°C) for 10-15 minutes.
Freezing
Freezing is not recommended for this dish. Because zucchini and tomatoes have a high water content, the cellular structure breaks down during freezing, which can result in a soggy consistency upon thawing.
