How to Make It
Cook ground beef in a large skillet over medium heat 5 to 6 minutes, stirring until it crumbles and is no longer pink. Drain.
Stir in chopped tomatoes and next 4 ingredients; cook 5 minutes. Add tomato paste and bay leaf, and simmer 30 minutes.
Cook egg noodles according to package directions; drain.
Stir together cooked egg noodles, chopped green onions, and sour cream until blended.
Place noodle mixture in bottom of a lightly greased 13- x 9-inch baking dish. Top with beef mixture; sprinkle evenly with cheeses.
Bake, covered with aluminum foil, at 350° for 35 minutes. Uncover casserole, and bake 5 more minutes. Garnish, if desired.
Note: Freeze casserole up to 1 month, if desired. Thaw in refrigerator overnight. Bake as directed.
To lighten: Substitute low-fat or fat-free sour cream and 2% reduced-fat Cheddar cheese. Reduce amount of cheeses on top to 1/2 cup each.
