In a skillet, combine browned ground beef, chopped onion, garlic powder, garlic salt, spaghetti sauce and tomato paste. Simmer over med. heat for 15-20 min. Cook pasta according to package directions. (If freezing, do NOT cook pasta). Place half of the pasta in the bottom of a 9x13 pan. Top with half of the meat sauce. Spread 1 c. sour cream on top and sprinkle with 1/4 c. parmesan cheese. Then sprinkle with 1 1/2 c. Mozzarella cheese. Repeat layers. If freezing, see directions below. Otherwise, cover and bake at 375 for 45 minutes. Uncover and bake for 10 more minutes.

Freezing directions: There is no need to cook pasta if freezing this recipe. Place carsserole in a disposable pan. Cover with plastic wrap and then aluminum foil. Make sure to remove plastic wrap and re-cover with foil before baking.

I will be interested to see if it works well to not precook the pasta. I figure we all have a bit of a learning curve on this- so please be patient!
