FAQs
Can I use other types of cheese in this casserole?
Yes, you can substitute mozzarella with provolone, cheddar, or a blend of your favorite cheeses to suit your taste.
Do I need to peel the zucchinis?
Peeling is not necessary as the skin softens during baking and adds extra nutrients, but you can peel them if you prefer a softer texture.
