Baked Ziti Casserole

Bring a large pot of lightly salted water to a boil. Cook ziti in boiling water until cooked through but firm to the bite, about 13 minutes; drain. Rinse ziti with cold water until cool; drain.

Preheat oven to 375 degrees F (190 degrees C).

Mix ziti, ricotta cheese, 1 1/2 cups tomato sauce, mozzarella cheese, egg, salt, and pepper in a large bowl.

Spread 1/2 cup tomato sauce into the bottom of a 2 1/2-quart shallow baking dish. Pour ziti mixture into the dish. Top with remaining 1 1/2 cup tomato sauce and Parmesan cheese.

Bake in preheated oven until sauce and cheese layer is bubbly and lightly browned, about 30 minutes. Let cool 10 minutes before serving.
