Frequently asked questions
Can I make this ahead of time?You can prep it ahead of time but it is best baked and eaten warm, directly out of the oven.Can I freeze this casserole?I wouldn't advise it. Zucchini is a watery vegetable, so freezing it will make the casserole soggy.How long will it keep in the refrigerator?It will easily keep up to 3 days. To reheat, place in the microwave until warmed.Can I make this into a complete meal?Absolutely! I sometimes add shredded or chopped up rotisserie chicken or cooked ground beef on top of the zucchini after it is baked and before sprinkling on the cheese.
