Heat the olive oil in a Dutch oven or large, wide pot over medium-high heat. Add the sausage and cook, breaking up clumps with a wooden spoon, until brown, about 6 minutes. Add the Marinara and 3 1/2 cups water and bring to a boil. Add the pasta, then partially cover and cook, stirring occasionally, until the pasta is al dente and the sauce is coating it nicely, about 16 minutes. Stir in the mozzarella and ricotta, then sprinkle with the Parmesan and basil, and serve.
Classic Marinara Sauce:
Heat the olive oil in a large saucepan over medium heat. Add the garlic and cook, stirring frequently, until it just turns golden, 3 to 4 minutes. Add the tomatoes, Italian seasoning, basil, 1 teaspoon salt and a few grinds of fresh pepper. Bring to a simmer and cook, stirring occasionally, for 7 minutes. Take off the heat and stir in the butter until melted. Add salt and pepper to taste.
