Preheat the oven to 375°F and bring 4 quarts of water to a boil.
Once boiling, pour the pasta into the water and cook al dente according to the instructions on the package.
In a medium mixing bowl, mix the Alfredo sauce, marinara sauce, cream cheese, petite diced tomatoes and garlic powder and Italian seasoning to taste.
Drain the pasta and mix with the sauce created in the step above.
Butter a baking dish and layer half of the pasta mixture on the bottom and spread it out evenly. Then add the sausage, half of the shredded cheese and the ricotta cheese.
Spread them out then add the other half of the pasta mix. Top with the rest of the shredded cheese.
Bake at 375°F for 25 minutes. Increase the temperature to 425°F and cook for an additional 3 minutes to get a good golden brown color.
