Brown the meat in a skillet over medium heat and drain the fat.
While you’re cooking the meat, bring a large pot of water to a boil on the stovetop.
Also, if you plan on baking your lasagna immediately, preheat your oven to 400 degrees.
When the water boils, cook the lasagna noodles according to package instructions.
You will probably only need 9 noodles, but I always cook an extra one, just in case a noodle is torn or messed up.
Stir the noodles a few times while they’re boiling to keep them from sticking together.
Drain the noodles and rinse them under cool water.
In the skillet, pour the tomato sauce over the meat and stir it up. Add the herbs if desired.
In a small bowl, mix together the egg and cottage cheese until thoroughly combined.
Spray a 9 by 13 baking pan with non-stick cooking spray.
At the bottom of the pan, spread about one-fourth of a cup of the tomato sauce mixture. Cover the sauce with three noodles, making a layer of noodles.
Ladle about half of the remaining tomato sauce and meat mixture on top of the noodles, spreading the sauce to cover the noodles.
Spoon about one-third of the cottage cheese mixture over the tomato sauce and spread it around to evenly cover the sauce and noodles.
Sprinkle about one-third of the mozzarella over the top of the sauce-cheese mixture.
Top this with another layer of noodles. Cover this layer with the remaining tomato sauce.
Spoon about half of the remaining cottage cheese mixture over the tomato sauce, spreading it evenly, and sprinkle mozzarella over all of it.
Top with another layer of lasagna noodles. Spread the rest of the cottage cheese mixture over the top of the noodles, and sprinkle the remaining mozzarella cheese on top of that.
At this point you can go ahead and bake the lasagna if you plan on eating it soon.
However, if you are preparing it for later on or for up to two days in the future, cover it tightly with aluminum foil and store it in the refrigerator until you’re ready to bake it.
When you’re ready to bake it, cover the lasagna with aluminum foil and bake at 400 degrees for about an hour.
Remove the foil about 40 minutes into the baking time to allow the cheese on top of the dish to brown. It is finished when the top is browned and the sauce is bubbly.
Allow the lasagna to rest for about ten to fifteen minutes before you cut it for serving. This will help the dish firm up and cut more cleanly.
