Preheat the oven to 375°F (190°C) and lightly grease a small baking dish or oven-safe skillet.
Cook the pasta in salted boiling water until al dente, then drain and set aside.
In a large bowl, combine ricotta cheese, 1 cup of mozzarella, parmesan cheese, Italian seasoning, garlic powder, black pepper, and red pepper flakes. Mix until creamy.
Add the cooked pasta and marinara sauce to the bowl. Stir gently until everything is evenly coated.
Transfer the mixture into the prepared baking dish and spread evenly.
Sprinkle the remaining mozzarella cheese over the top.
Bake for 20–25 minutes until the dip is hot and bubbly and the cheese is fully melted.
Optional: Broil for 2–3 minutes to create a golden cheesy top.
Remove from the oven and let it rest for about 5 minutes before serving. Garnish with fresh parsley or basil.
