Preheat oven to 350 F.
Prepare the pasta noodles per the package instructions, then set aside.
In a large skillet, combine the hot sausage, ground beef, onion, and garlic. Cook until the meat has browned, then drain about 1/2 the fat.
Add the sauce along with the Italian seasoning and broth then heat to a simmer. Let cook 10 minutes.
Meanwhile, in a mixing bowl, combine ricotta, parsley, and 1/2 cup Parmesan.
Lightly grease a 9 x 13 baking pan, then place the first layer of pasta down. That should use 4 noodles.
Spread 1/3 of the meaty sauce over the noodles, then sprinkle with about 1/2 cup mozzarella.
Place another layer of noodles down, then spread on 1/2 the ricotta mixture. Spread on another 1/3 of the meat sauce, topped with mozzarella.
Add another layer of noodles, then use the second half of the ricotta. And finally, the last of the meat sauce.
Sprinkle the top generously with mozzarella and Parmesan. Tent the top with foil (to avoid touching the cheese), then bake for 40 minutes. Remove the foil and bake for 5 more.
Let cool 5 to 10 minutes before slicing, then enjoy!
