Preheat your oven to 375°F (190°C).

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

In a large skillet over medium heat, brown the ground beef.

Once the beef is browned, stir in the marinara sauce and let it simmer for about 5 minutes.

In a bowl, mix together the ricotta cheese, egg, Italian seasoning, and a pinch of salt and pepper.

In a 9x13 inch baking dish, spread a layer of meat sauce on the bottom, followed by noodles, cheese filling, and mozzarella.

Repeat these layers, ending with meat sauce and a topping of mozzarella and Parmesan cheese.

Cover the baking dish with aluminum foil and bake for 25 minutes.

After 25 minutes, remove the foil and bake for an additional 15 minutes until the cheese is bubbly and golden.

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