  • 1 1/2 lbs sirloin steak or chuck roast cut into 1" strips
  • 8 oz fresh sliced mushrooms
  • 1 large yellow onion cut in half, sliced 1/4" across
  • 3 tablespoons steak seasoning
  • 1 tablespoon worcestershire
  • 1 tablespoon Better than Bouillon Beef
  • 1 tablespoon dijon mustard
  • 1/4 cup sherry
  • 3/4 cup beef stock
  • 2 cups sour cream


  • Add beef, onions, mushrooms, steak seasoning, Worcestershire, mustard and Better than Bouillon to the insert of a slow cooker. Pour sherry and beef stock over mixture and stir to combine. 
  • Cover and cook on LOW for 6 hours. 
  • Uncover and stir in sour cream. Turn to HIGH and cook partially covered for 30 minutes. 
  • Serve over egg noodles. 


I like to use steak seasoning because it takes care of my salt, pepper, garlic powder and onion powder so I don't have to add them all individually. If you don't have steak seasoning on hand, use a combination of the above.
If you'd like to add a condensed soup to this, I recommend using golden mushroom soup. Add this at the beginning with the other ingredients, and then cut your sour cream in half at the end.
