Preheat oven to 375°F (190°C).
Boil pasta in salted water for 2 minutes less than the package instructions for al dente.
In a large mixing bowl, combine marinara sauce, heavy cream, minced garlic, oregano, and red pepper flakes.
Add the cooked pasta and meatballs to the sauce mixture and toss to coat evenly.
Transfer the mixture to a 9x13 inch baking dish.
Sprinkle mozzarella and parmesan cheese evenly over the top.
Bake for 25 to 30 minutes until the cheese is melted and bubbling.
Garnish with fresh basil before serving.
