Preheat oven to 350℉.
Brown and crumble the meat in a skillet. Remove from heat when done.
Spray your sheet pan with non stick spray.
Combine the cottage cheese, egg, and Italian parsley in a bowl.
To start the layers, spread 4 ounces of marinara sauce on the bottom of the casserole dish.
Arrange 3 lasagna noodle sheets next to each other on the bottom of the pan over the sauce.
Spoon ¼ of the cottage cheese mixture over the pasta sheets. Just use the spoon to try to layer it as even as you can. It does not have to be exact because it will melt together in the oven.
Hand sprinkle ¼ of the Pecorino and Parmigiano Reggiano cheeses over the cottage cheese.
Spoon ¼ of the cooked, crumbled meat over the cottage cheese and grated cheese layer.
Pour about 11 ounces or ½ of your jar of marinara sauce over the crumbled ground meat. Save the empty jar.
Spread 1 cup or ½ of a shredded mozzarella cheese package over the marinara sauce. This completes the first layer.
Repeat the layer 3 more times starting with the lasagna sheets for a total of 4 layers.
Add ¼ cup of water to one of the empty marinara sauce jars and shake it for 10 seconds to get the remaining sauce loose. Pour this water into the 2nd marinara jar and shake it up. Next, pour this tomato water around the lasagna casserole.
Line the cookie sheet with aluminum foil and place the casserole dish on top of the cookie sheet to catch the drips. Spray non-stick oil on one side of a second sheet of aluminum foil and cover the casserole dish tightly.
Bake covered in the oven for 1 hour and 15 minutes.
Remove the alumimun foil from the casserole dish and bake uncovered 15 minutes more.
Remove from the oven and let rest for 30 minutes.
Sprinkle chopped fresh basil over the lasagna before serving.
