Preheat the oven to 375 degrees and lightly grease an 8x8 inch baking dish.

Bring a large pot of salted water to a boil and cook the lasagna noodles according to package directions until just tender. Drain and set aside.

In a mixing bowl, combine the ricotta cheese, egg, dried basil, salt, black pepper, and half of the Parmesan cheese. Stir until the mixture is smooth.

Spread 1 cup of marinara sauce across the bottom of the prepared baking dish.

Lay 2 noodles over the sauce, then spread half of the ricotta mixture on top. Sprinkle 1/2 cup of mozzarella over the ricotta.

Repeat the layers once more with sauce, noodles, the remaining ricotta mixture, and another 1/2 cup of mozzarella.

Add the final 2 noodles, the remaining marinara sauce, the rest of the mozzarella, and the remaining Parmesan.

Cover the dish with foil and bake for 25 minutes. Remove the foil and bake 10 minutes more until the cheese on top is lightly browned. Let the lasagna rest 10 minutes before slicing.
