Brown ground beef in a skillet over medium heat. After the beef is no longer pink, add spaghetti sauce and simmer.
Cheese layer
While beef is browning, add all ingredients for cheese layer in a bowl and stir well. (Cottage cheese, mozzarella cheese, parmesan cheese, cream cheese and an egg.
Noodle Layer Assembly
Spray the bottom of your lasagna pan with cooking spray.
Add 1 1/2 cups of the meat/spaghetti sauce layer. Tip pan to coat the entire bottom of the pan.
Arrange the uncooked lasagna sheets (4 across) on top of the meat layer.
Scoop 1 1/2 cups of the cheese onto the lasagna noodles, and spread into an even layer with your spoon (I like to drop it in half cups across the pan for easier spreading.
Add 1 1/2 cups of meat sauce on top of the cheese, and spread with the back of your spoon into an even layer.
Repeat layers 2 more times (for a total of 3 layers of noodles, 3 layers of cheese, and there will be 4 layers of meat sauce if you include the layer under the first row of noodles.)
Sprinkle the top of your final meat layer with extra mozzarella and parmesan cheese.
Spray a large piece of aluminum foil with cooking spray and cover the lasagna, pinching it around the edges to keep the steam in.
Bake at 350 degrees for 50 minutes. Remove foil and cook for 10 more minutes to brown the top layer of cheese.
MOST IMPORTANTLY: Allow your lasagna to sit and cool for at least 30 minutes. This makes it easier to scoop out and keep it's shape, (rather than scooping a sloppy, soupy mess)

Notes
NOTE: My best tip and must be repeated.....Let lasagna cool for 30-45 minutes before serving so it's easy to cut and keep it's shape.This lasagna is EVEN BETTER reheated the next day!!
