Heat oven to 375°F. Lightly oil a 9x13-inch baking dish.
Whisk sauce, water, Italian seasoning, garlic powder, onion powder, red pepper flakes, salt, and pepper in a bowl.
Scatter dry pasta and frozen meatballs into the prepared dish. Pour the seasoned sauce over and stir to coat evenly.
Cover tightly with foil and bake for 30 minutes.
Remove foil, stir well, then dollop ricotta over the top. Sprinkle with mozzarella and Parmesan.
Bake uncovered 12 to 18 minutes, until pasta is tender and cheese is bubbly and lightly golden. Broil 1 to 2 minutes if you like extra color.
Rest 5 minutes, then garnish with parsley. Taste and adjust salt and pepper before serving.
