Preheat oven to 375°F (190°C).
Cook lasagna noodles according to package instructions. Drain and set aside.
In a mixing bowl, combine ricotta cheese, 2 cups of mozzarella cheese, ½ cup of Parmesan cheese, salt, and pepper.
Spread a thin layer of marinara sauce on the bottom of a baking dish.
Layer 4 lasagna noodles over the sauce. Spread ⅓ of the ricotta mixture over the noodles. Top with ⅓ of the remaining marinara sauce and ⅓ of the remaining mozzarella cheese. Repeat layers twice more, ending with mozzarella cheese.
Sprinkle the remaining Parmesan cheese on top.
Cover with aluminum foil and bake for 25 minutes. Remove foil and bake for an additional 20 minutes, or until cheese is bubbly and golden brown.
Let lasagna cool for 10 minutes before serving.
