Preheat oven to 400°F. Lightly grease a 9x13-inch baking dish with olive oil or cooking spray.
In a large bowl, mix together the cooked ground turkey, dry pasta, marinara, broth, zucchini, spinach, blended cottage cheese, parmesan (if using), garlic, Italian seasoning, salt, and pepper.
Pour the mixture into the prepared baking dish and spread evenly.
Cover tightly with foil and bake for 35 minutes.
Remove the foil, stir gently, and bake uncovered for another 10–15 minutes, or until the pasta is tender and the sauce is creamy and thickened.
Let the pasta rest for 5–10 minutes before serving to allow the sauce to set.
