Cook lasagna noodles according to package directions. Meanwhile, cook the ground Italian sausage in a skillet for 10 minutes, then set aside.

Sauté diced onion for 5 minutes, then add minced garlic and cook for 30 seconds before adding sausage and marinara sauce to the pan.

Mix ricotta cheese, 1 ½ cups of mozzarella, parmesan, parsley, egg, ½ tsp of salt, and pepper in a large bowl.

Lay out the cooked noodles and spread cheese filling onto each noodle, then top with a small amount of meat sauce.

Pour ½ cup of marinara sauce evenly into the bottom of a baking dish. Then gently roll each noodle and place it in the dish, seam side down.

Top the roll ups with the remaining meat sauce and shredded mozzarella cheese. Then cover with foil and bake.
