How to Make Zucchini Pizza Casserole
-
Preheat oven to 400°F (200°C). This step ensures even baking and a perfectly crisp crust for your casserole.

Zucchini Pizza Casserole Recipe FAQs
What type of zucchini should I use for the casserole?
Absolutely! Choose firm, medium-sized zucchinis without any dark spots or wrinkles. Look for ones that feel heavy for their size, as they will contain more moisture and flavor.
How should I store leftover Zucchini Pizza Casserole?
Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. If you notice it starting to dry out, you can add a splash of pizza sauce to keep it moist before reheating.
Can I freeze the Zucchini Pizza Casserole?
Yes! To freeze, wrap individual portions tightly in plastic wrap or aluminum foil, then place them in a freezer-safe container or bag. This can keep for up to 3 months. When you’re ready to enjoy it again, simply thaw in the refrigerator overnight and reheat as directed.
What can I do if the crust turns out soggy?
Very! To avoid a soggy crust, ensure you thoroughly squeeze out excess moisture from the shredded zucchini—this is a crucial step! If you’ve already baked and it’s still soggy, try returning it to the oven for an additional few minutes to firm it up. You can also bake the crust slightly longer at the beginning to create a sturdier base.

Indeed! This Zucchini Pizza Casserole is naturally gluten-free and can be made low-carb. To accommodate allergies, consider using dairy-free cheese and swapping the ground beef for lentils for a vegetarian option. Always double-check labels on sauces and cheese for hidden gluten or allergens!
