Preheat the oven to 350°F and grease a 13x9-inch baking dish.
Cook the pasta al dente according to the package directions; drain.
In a large Dutch oven, combine the marinara sauce, alfredo sauce, ricotta, and 1 cup of Italian blend cheese. Cook over medium heat until the cheese has melted and the sauce begins to simmer. Add the cooked pasta and stir.
Pour the mixture into the prepared baking dish and top with the remaining 1 cup of Italian blend cheese.
In a small bowl, combine the Parmesan, panko, granulated garlic, and melted butter. Mix well and sprinkle over the pasta.
Bake for 30 to 40 minutes, until bubbly and golden brown. Remove from the oven and let stand for 10 minutes before serving. Garnish with fresh parsley if desired.
