Crockpot beef stroganoff without cream of mushroom soup only requires 5 ingredients and cooks all day in the slow cooker. Absolute best way to cook stew meat to tender with a creamy sauce.
Salt the cubed stew beef (and carrots are optional) and add in the crockpot and mix with packet of onion dip mix. Add your beef broth and onions and cook on low for a good 6 -8 hrs. (this is best so the meat gets really tender).
Before serving, about 30 minutes prior, whisk together some of the hot broth in your slow cooker, your sour cream, and cornstarch to create a thick rue and add that to the crockpot to thicken up the broth.
Put lid on for another 30 minutes so it all melds together. Add salt and pepper to taste. Serve over egg noodles cooked separately.
