Preheat Oven to 350 degrees. Brown the Hamburger and soften the onion until Hamburger is no longer pink. Add the Spaghetti Sauce and mix well, warm and then take off heat. Spray a 9 by 11 casserole dish with cooking spray.

Take 1 1/2 Cups of meat sauce and make a layer at the bottom of the casserole dish. Use 5 lasagna noodles to make the next layer. I did 4 noodles long ways and then broke another so I could fit the last the other direction. Feel free to lay them whatever works best for your dish.

Mix the Cottage Cheese and sour cream together and blend well. Pour half of the cottage cheese mixture and spread over the lasagna noodles to make the next layer.

Your next layers is Mozzarella slices. I used 10 with 2 of those slices cut in half. Depending on your cheese you may need more or less. You could also use shredded mozzarella cheese.

Pour half of the Meat Sauce and spread making a layer. Sprinkle half of the Parmesan cheese over the meat sauce.

Next layer if 5 noodles again. I lay mine just like before so it's easy when cutting. Pour the rest of the cottage cheese mixture over the noodles and spread into a layer.

10 Slices of Mozzarella is your next layer again. Pour the remaining meat sauce onto the mozzarella and spread into a layer.

Sprinkle the remaining Parmesan cheese over the meat sauce. Your last layer will be 10 slices of Mozzarella again. Now carefully pour that 1/2 cup of water at the edge of the casserole dish so the water is going towards the bottom of the dish.

Cover with Foil. Bake at 350 degrees for one hour. Then take the foil off and bake for another 20 minutes or until bubbly. Then remove the casserole dish and let it sit for 20 more minutes before eating. If you use the disposable casserole dish containers, have it sit on a cookie sheet for support.
