Preheat your oven to 375 degrees Fahrenheit.
Boil a large pot of salted water and cook the ziti until just barely al dente, usually two minutes less than package instructions.
Brown the ground beef and ground turkey in a large skillet over medium-high heat until no pink remains.
Add the minced garlic to the meat mixture and sauté for one minute until fragrant.
Stir the marinara sauce and Italian seasoning into the skillet, simmering for five minutes.
Drain the ziti and return it to the pot, tossing with one cup of the meat sauce.
Spread a thin layer of sauce in the bottom of a 9×13 baking dish.
Layer half of the ziti, half of the ricotta cheese, half of the mozzarella, and half of the remaining meat sauce.
Repeat layers with the remaining pasta, ricotta, meat sauce, and mozzarella.
Top with the grated Parmesan cheese.
Bake for 20 minutes until the cheese is melted and bubbling.
