Preheat the oven to 375 degrees Fahrenheit (190 degrees Celsius).
Cook the lasagna noodles according to package directions in a large pot. Drain the water and set it aside.
Cook the ground beef in a separate pan until it is browned. Drain and set aside any extra grease.
Begin by spreading a layer of marinara sauce on the bottom of a 913 baking dish.
The lasagna noodles are layered on top, followed by ricotta cheese, ground meat, and mozzarella cheese. Continue layering until all of the ingredients have been utilized.
Bake for 30 minutes with the dish covered in aluminum foil. Remove the foil and continue baking for another 15 minutes, or until the cheese has melted and is bubbling.
Let the lasagna cool for 10 minutes before serving. Garnish with parsley, if desired. Enjoy!
