Boil the Noodles: Bring a large pot of salted water to a boil. Cook the lasagna noodles according to package instructions until al dente, about 8-10 minutes. Drain and lay flat to prevent sticking.

Brown the Beef: In a large skillet over medium heat, add the ground beef. Cook until browned, about 5-7 minutes. Drain excess fat.

Make the Meat Sauce: Add the pasta sauce and 1/4 cup of water to the skillet. Stir and let it simmer for about 10 minutes until thick but pourable.

Mix the Cheese Filling: In a medium bowl, combine ricotta, mozzarella, Parmesan, eggs, parsley, salt, and pepper. Stir until creamy and well incorporated.

Preheat the Oven: Preheat your oven to 375°F (190°C).

Layer the Lasagna: Spread a thin layer of meat sauce in a 9x13 inch dish. Layer noodles, cheese mixture, and repeat until all components are used. Finish with meat sauce and mozzarella on top.

Bake the Lasagna: Cover with foil and bake for 30 minutes. Remove foil and bake for another 15 minutes until cheese is bubbling and golden.

Let it Rest: Allow the lasagna to sit for 10-15 minutes before slicing.
