Frequently Asked Questions

Do I need to peel the zucchini?
No, peeling is optional. The skin is edible and contains nutrients. However, peeling the zucchini can create a softer texture, which some people prefer in casseroles.

Be sure to drain the cooked zucchini thoroughly after steaming or boiling. You can also pat it dry with paper towels to remove excess moisture before mixing it with the other ingredients.

Absolutely. While cheddar cheese provides a rich flavor, you can substitute mozzarella, Monterey Jack, Colby Jack, or a blend of your favorite cheeses.
Can I freeze zucchini casserole?
Yes. Allow the casserole to cool completely, then wrap it tightly and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
What can I serve with zucchini casserole?
This casserole pairs well with grilled chicken, roasted turkey, baked fish, pork chops, or a fresh green salad for a complete meal.
