Preheat the oven to 350 degrees F. Stir the ricotta and the eggs in a medium bowl.
Spread 1 cup sauce on the bottom of a 13 x 9 x 2-inch baking dish. Layer with 3 lasagna noodles, 1 1/3 cups ricotta mixture, 1 1/2 cups mozzarella, 1/2 cup Parmesan and 1 1/2 cups sauce. Repeat to make 2 more layers. Top with the remaining noodles, sauce, mozzarella and Parmesan cheeses. Cover the baking dish.
Bake at 350 degrees F for 45 minutes. Uncover and bake for 15 minutes or until the lasagna is hot and bubbling and the cheese is melted.
Cut the bread into 2-inch diagonal slices. Serve the bread with the lasagna.
