Method
- Season beef with salt and pepper. Layer onions and mushrooms in the crockpot, then add beef strips.
- Whisk beef broth, tomato paste, onion soup mix, Worcestershire sauce, paprika, and thyme until smooth. Pour over beef.
- Cover and cook on low for 6-8 hours or high for 3-4 hours.
- Cook egg noodles separately according to package directions.
- Mix flour with 1/4 cup hot cooking liquid to create a slurry, then stir into crockpot to thicken.
- Remove from heat, fold in sour cream and butter. Serve over cooked noodles, garnish with parsley.
Notes
Use room-temperature sour cream to prevent curdling. Cook noodles separately to avoid mushiness. Ensure liquid covers 3/4 of ingredients. Store refrigerated for up to 4 days or frozen (without dairy) for up to 3 months, adding fresh sour cream when reheating.
