Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish lightly with butter or cooking spray.

In a large skillet, cook ground beef over medium heat. Add onion and garlic. Cook until meat is browned.

Stir in tomato sauce, tomato paste, Italian seasoning, salt and pepper. Simmer 10 minutes for flavors to combine.

In a bowl, combine ricotta cheese, 1 cup mozzarella, Parmesan and beaten egg. Mix until smooth and creamy.

Cook lasagna noodles according to package instructions. Drain and lay flat on a clean towel to prevent sticking.

Spread a thin layer of meat sauce on the bottom of the baking dish. Layer 3 noodles on top evenly.

Spread one-third of the cheese mixture over noodles. Top with a layer of meat sauce.

Repeat noodles, cheese and meat sauce two more times. End with a final layer of mozzarella on top.

Cover the dish with aluminum foil. Bake 25 minutes. Remove foil and bake an additional 10 minutes until cheese is melted and bubbly.

Allow lasagna to cool 5 minutes before slicing. Serve warm and enjoy a comforting homemade meal.
