Ingredients
Method
- Combine the beef cubes, mushrooms, onion, garlic, broth, and Worcestershire sauce in the crock pot insert.
- Stir the ingredients well until the meat is evenly coated with the seasonings.
- Cover the slow cooker and cook on low for 7 to 8 hours until the beef is fork-tender.
- Whisk the cornstarch and water mixture into the pot during the last 30 minutes to thicken the sauce.
- Stir in the room-temperature sour cream immediately before serving to prevent curdling.
Notes
Sear the beef cubes in a hot skillet before adding to the slow cooker for extra Maillard reaction flavor. Avoid using low-fat sour cream as it tends to break down and curdle more easily than full-fat versions.
