Step 4

Step 5

Make 1 layer of zucchini slices in the prepared baking dish. Cover with 1/2 of the sauce. Add another layer of zucchini slices. Spread ricotta mixture on top. Sprinkle with 1 cup mozzarella cheese. Add another layer of zucchini slices; cover with the remaining sauce and top with 1 cup mozzarella cheese and Parmesan cheese. Cover baking dish with aluminum foil.

Step 6

Bake in the preheated oven for 30 minutes. Remove aluminum foil and bake until top is golden, about 15 minutes more.
