Cook noodles to al dente according to the package directions, then cool and set aside.
Mix the cottage cheese, egg and onion powder together in a small bowl.
Mix the mashed potatoes ( it's easier if they are warm!) and cheddar cheese together in a small bowl.
Fry the butter, onions and bacon together until soft and cooked.
In the bottom of a 9x13 pan, lay three lasagna noodles to cover the bottom. ( see video above for this part if you need help!). There is one extra in case you need patching - it happens!!!!
Spread the cottage cheese mixture over those noodles.
Lay three more noodles on top. Spread the potato mixture over top, slowly and carefully. It helps if you heat it up.
Lay three more noodles on top. Pour the butter/bacon/onion mixture all over the top evenly. If wanted, add more shredded cheddar cheese to the top!
Bake in a 350 °F oven for 50-60 minutes, until the internal temperature reaches a 180-190 degrees. ( this means the egg/cottage cheese layer is set and cooked).
Remove and let sit for a few minutes, then slice and serve!
This freezes AMAZINGLY!!!! Make two and freeze one in the pan, well covered, for another night!
