Here is my version:
Stroganoff Skillet
1 lb ground beef
1 medium onion, chopped
1 can cr of mushroom soup
1 cup sour cream
1 cup beef broth
1/2 cup water
3 cups wide egg noodles, uncooked
Brown the Gr beef and onions in a large deep skillet over medium heat.
Drain grease or blot with paper towel.
Gradually blend in all remaining ingredients. Bring to a boil.
Reduce heat and cover skillet with a lid. Simmer for 10 minutes
or until noodles are tender.
I'm sure the noodles could be cooked separately, but you might
need to omit the water in the recipe. I have not ever made
it that way.
