Sauté garlic in olive oil, cook shrimp until pink, then add crab and seasonings and remove from heat.
Mix ricotta, mozzarella, Parmesan, cream, and parsley until smooth.
Preheat oven to 375°F and layer sauce, noodles, cheese mixture, and seafood in a baking dish.
Top with remaining cheeses and breadcrumbs, cover, and bake twenty five minutes, then uncover and bake fifteen more minutes.
Rest ten minutes before slicing and serving.
