Preheat your oven to 350°F (175°C).
Stuff each uncooked manicotti shell with a string cheese stick and arrange them in a single layer in a baking dish.
Pour about three-quarters of the marinara sauce over the stuffed shells, ensuring they are mostly covered.
Pour the water around the edges of the dish. This will help steam and cook the pasta.
Sprinkle the diced white onion over the sauce.
Season evenly with garlic powder and Italian seasoning.
Top with the cooked and crumbled Italian sausage, followed by the remaining marinara sauce.
Cover the baking dish tightly with aluminum foil.
Bake for 30 minutes.
Carefully remove the foil. Top the casserole with shredded mozzarella and grated Parmesan cheese.
Garnish with dried parsley flakes.
Return the dish to the oven, uncovered, and bake for another 10 minutes, or until the cheese is melted and bubbly.
Let it rest for a few minutes before serving.
Store covered in the refrigerator for up to 3 days. Reheat covered in a 350°F oven for 20–25 minutes. Freezes well for up to 2 months; thaw overnight in the refrigerator before reheating.

Yes. Stuff the shells, arrange in the baking dish, cover with sauce and cheese, then cover tightly and refrigerate up to 24 hours. Bake directly from the fridge, adding 5–10 minutes to the baking time.
