In a large pan, over medium heat, cook the meat until browned.
Then, drain any fat and return the pan to the stove.
On a cutting board, dice an onion and then add it to the cooking meat.
Cook the onion until tender and translucent.
If desired, add 1 can of mushrooms to the pan.
As this pasta does not need to boil ahead of time, add the recommended water to the meat per the box's directions.
If you are choosing to use boil pasta, then follow the directions on that box.
Pour the spaghetti sauce into the pan with the cooked meat, mushrooms, onion and water, then let this simmer and cook for up to 1 hour before assembling lasagna.
Pour the cottage cheese into a medium bowl.
Shred 4-oz parmesan cheese and 8-oz mozzarella into a bowl with Cottage Cheese and mix together in a bowl, then set aside.
Preheat oven to 425 degrees.
Assemble the Lasagna
Spray a 9 X 13-inch baking pan with non-stick spray and then set aside.
Place 1/4 of the meat sauce on the bottom of the prepared pan, then spread it around using a spatula.
Then place 4 uncooked lasagna sheets in the pan on top of the thin layer of sauce.
Top the pasta with half of the Cottage Cheese mixture and then spread around with a spatula.
Place the next layer of pasta on top of the Cottage Cheese mixture.
Then, using a large spoon, scoop sauce onto pasta carefully - keep 1/3 reserved for the top.
Add the next layer of pasta on top of the sauce.
Then, repeat each layer twice.
When the last pasta layer is placed, pour the remaining sauce on top and spread it evenly over the pasta.
Sprinkle shredded cheese on the top of the Lasagna and then, to avoid drips, place your Lasagna pan on a large baking sheet lined with aluminum foil. This helps cleanup be a breeze!
Finally, bake at 425 degrees for 50-55 minutes.
Remove the Lasagna from the oven and let it rest for 5-10 minutes before serving.
