Three-Cheese Pasta Bake

Bring a large pot of lightly salted water to a boil. Add ziti and cook, stirring occasionally, until tender yet firm to the bite, about 8 minutes. Drain. Preheat the oven to 350 degrees F (175 degrees C). Mix and sour cream together in a bowl. Add cooked pasta and stir until evenly coated. Mix ricotta cheese, Parmesan cheese, and eggs together in another bowl. Pour 1/2 of the pasta mixture into a 9x13-inch baking dish. Spread ricotta-egg mixture over the top. Cover with remaining pasta mixture. Sprinkle, or completely cover, with mozzarella cheese. Bake in the preheated oven until bubbly, about 30 minutes.
