Cube the steak, then cut up the potatoes into about 2-inch pieces.
Add all of the ingredients to the Slow cooker. Mix everything together.
Cooked on low for 5-7 hours or on high for 3-4 hours. Cooking it low and slow produces the most tender steak bites. Cook time will depend on the size of the beef chunks (and potato pieces). Start checking for doneness at the 5 hour mark on low, and at the 3 hour mark on high, to prevent drying out the meat.
Serve as is or with a green salad.
Notes
Add 1 cup of beef broth if you want more gravy. You may need to thicken it after cooking.See article for othet tips, variations, etc.
