Preheat oven to 375°F (190°C).

Brown ground beef in a large skillet over medium-high heat.

Drain off any excess fat from the beef.

In a saucepan, combine the browned beef, spaghetti sauce, and water.

Bring the mixture to a simmer and cook on low heat for 10 minutes, stirring occasionally.

In a separate bowl, mix together the ricotta cheese, half of the mozzarella cheese, parmesan cheese, parsley, salt, and pepper.

In a baking dish, spread a thin layer of the meat sauce mixture.

Layer lasagne noodles over the sauce.

Spread half of the ricotta cheese mixture over the noodles.

Repeat layers: sauce, noodles, ricotta mixture.

Top with the remaining mozzarella cheese.

Cover the baking dish with foil.

Bake in the preheated oven for 25 minutes.

Remove the foil and bake for an additional 15 minutes, or until the cheese is melted and bubbly.

Let stand for 10 minutes before serving.
