To prepare a zucchini lasagna recipe, you'll need: Zucchini, ricotta, mozzarella cheese, tomato sauce, and parmesan cheese. Preheat the oven to 350 degrees F (180 degrees C). Peel and slice the zucchini. Cut the mozzarella into 1/4-inch slices. Toss the slices with the olive oil, salt and pepper. Spread the cheese mixture on the bottom and sides of an 8x8x2-inch baking dish. Bake for 35 to 40 minutes, or until cheese is melted and bubbly. Remove from oven and let stand for 5 minutes before serving.
