Preheat the oven to 375°F (190°C).

In a large pot of boiling salted water, cook the lasagna noodles according to package instructions until al dente.

In a large skillet over medium heat, cook the ground turkey until browned, about 5-7 minutes.

In a mixing bowl, combine ricotta cheese, egg, half of the mozzarella, Parmesan, Italian seasoning, garlic powder, salt, and pepper.

Spread a thin layer of marinara sauce at the bottom of the baking dish.

Layer three noodles, half the turkey mixture, half the cheese mixture, and more marinara sauce.

Continue layering until all ingredients are used, finishing with noodles and sauce on top.

Sprinkle the remaining mozzarella cheese over the top.

Cover the baking dish with aluminum foil and bake for 30 minutes.

Remove the foil and bake for an additional 20 minutes until golden and bubbly.

Let the lasagna sit for 10-15 minutes before slicing.
