2 cups uncooked spiral pasta
2 pounds ground beef
2 small onions, chopped
1 garlic clove, minced
1 (26 ounce) jar spaghetti sauce
1 (4.5 ounce) jar sliced mushrooms, drained
1/2 cup sour cream
1/2 pound American cheese
2 cups shredded mozzarella cheese
1. Cook pasta according to package directions. Meanwhile, in a large saucepan, cook the beef, onions and garlic over medium heat until meat is no longer pink; drain. Stir in spaghetti sauce and mushrooms; bring to a boil. Reduce heat; cover and simmer for 20 minutes.
2. Place 1/2 cup to 1 cup of meat sauce in a greased shallow 2-1/2-qt. baking dish. Drain pasta; place half over sauce. Top with half of the meat sauce; spread with sour cream. Then top with American cheese and remaining pasta and meat sauce.
3. Sprinkle with mozzarella cheese. Cover and bake at 350 degrees F for 25-30 minutes. Uncover, bake 5-10 minutes longer or until bubbly.
As a side note.... I like to use more noodles and less meat. You could probably cute it down to 1 pound of beef. I also cut back on the cheese; just this last time I made it, I didn't even have enough room on top for the cheese. So I put a nice handful in the middle layer and also a bit on top. Don't be afraid to save calories by cutting back on the cheese. I only used about a cup of cheese total and it was still great.
