Bring a large pot of salted water to a boil. Add rigatoni and cook until just al dente, about 10 minutes, stirring occasionally. Drain thoroughly.
02 -
Transfer drained rigatoni to a large baking dish. Pour in marinara and Alfredo sauces, add shredded fontina and ricotta, and mix until all pasta is evenly coated.
03 -
In a bowl, combine 1 cup of the shredded mozzarella with panko breadcrumbs, grated Parmesan, and minced garlic; stir until well mixed.
04 -
Spread remaining 1 cup mozzarella evenly over the pasta mixture in the baking dish. Scatter the breadcrumb topping mixture in an even layer to cover the surface completely.
05 -
Bake uncovered at 350°F for 30 minutes, or until the topping is deeply golden and the edges are bubbling. For an extra crisp top, broil for the last 2 minutes if desired.

Remove from oven and let rest 10 minutes. Garnish with chopped fresh parsley before serving. Serve warm, directly from the baking dish.
