Preheat oven to 350°F and coat a large casserole dish with cooking spray.
Cook the pasta al dente according to package instructions, drain and set aside. If you are making the pasta ahead of time, toss with 2 teaspoons olive oil to prevent sticking and drying out.
In a large mixing bowl, stir together the ricotta cheese, egg, garlic powder, onion powder, salt, pepper and parmesan cheese.
To the ricotta mixture, add the cooked pasta, sausage and 1 cup of the mozzarella cheese. When combined, pour into prepared casserole dish.
Top with remaining 1 cup mozzarella cheese.
Bake, uncovered, for 25-30 minutes or until top cheese is melted and bubbly.
Remove and serve hot or wait until fully cooled before covering and refrigerating or freezing.
