In a Crock Pot/slow cooker, add 2 lbs of beef stew meat.
In a small bowl, mix 1 envelope of Lipton's Beefy Onion Soup Mix, I can of Campbell's Cream of Mushroom Soup, 1 soup can of water (or you can use beef broth/stock to make it extra beefy) and one tablespoon of Worcestershire sauce.
Whisk together and pour over the beef cubes. Stir to combine.
Put the lid on the Crock Pot and cook on low for 7-8 hours or high for 4-5 hours.
Once the meat is tender, add 2 tablespoons of flour and 2 tablespoons of water to a small bowl. Whisk together and stir into beef cubes.
Cook for a few minutes, until thickened. Serve over butter egg noodles.
