Preheat: Heat oven to 350°F (175°C). Grease a baking dish.
Filling: Mix fat free cottage cheese, basil, spinach, egg, red pepper flakes, salt to taste, and garlic powder until combined.
Noodles: Cook lasagna noodles per package until al dente (or use no-boil if that is what you have — package guidance). Drain.
Layer: Spread a thin layer of tomato sauce in the dish. Layer noodles, cottage-cheese filling, and more sauce. Repeat until ingredients are used, ending with sauce on top (reserve mozzarella for the second bake).
First bake (site stub): Bake at 350°F for 30 minutes.
Cheese finish (site stub): Top with shredded mozzarella. Bake 15 minutes more until cheese is melted and bubbly. Rest a few minutes before slicing.
