Bring 3-4 quarts of water to a boil, break spaghetti in half and cook as directed by the packaging, probably around 9-11 minutes. Strain when done.
Beat two eggs
Spray the bottom of your pie pan with non-stick spray.
In the bottom of your pie pan, mix noodles, ¼ cup of parmesan cheese and beaten eggs, while the eggs are still warm and pliable. Gently press down the noodles into the pan to make the “crust”.
Saute onions and butter together in a pan.
Add the onions, and 1 cup of sour cream on top of the noodles.
Brown the meat and drain off the excess oil. Add the seasonings, and the tomato sauce to the meat and simmer for 3-4 minutes to cook together.
Add the sauce mixture on top of the onions and sour cream in the pie pan.
Sprinkle shredded cheese over the top of the pie. Add the last tablespoon of parmesan cheese on top.
Bake for 25-30 minutes at 350o until the cheese is melted and starting to brown.
Let rest for 10 minutes before cutting to serve.
