Heat the oil in a 10 to 12-inch skillet. Add the onion and cook until translucent about 4 to 5 minutes. Add the garlic and cook for 1 more minute. Next, add the turkey and cook until no longer pink. This will take 7 to 8 minutes.
To the skillet with turkey, add the tomatoes, tomato paste, 2 tablespoons parsley, basil, 1 and ½ teaspoons of the salt, and ½ teaspoon pepper. Simmer, uncovered, over low heat, for 30 minutes, until thickened.
While the sauce is simmering, boil the noodles to al dente. Drain.
In a medium bowl, combine the ricotta, 1 cup of Parmesan, egg, the remaining parsley, remaining ½ teaspoon salt, and ¼ teaspoon pepper.
Ladle ⅓of the sauce into a 9x13-inch baking dish. Spread the sauce over the bottom of the dish. Then add the layers as follows: half the pasta, half the mozzarella, half the ricotta, and one ⅓ of the sauce. Add the rest of the pasta, mozzarella, ricotta, and finally, sauce.
Sprinkle with ¼ cup parmesan. Bake for 30 minutes, until the sauce bubbles.
Allow the lasagna to cool 10 minutes before cutting and serving.
Store in an airtight container in the refrigerator for up to 5 days. Reheat covered in the oven or microwave.
