Spray inside of crock with non stick spray and lay steaks on the bottom.
Wash and cut potatoes into 1" cubes with skins in tact and put around steak. Add broth or water until half of steak is sitting in the liquid (will vary depending on how large your pot is)
Sprinkle everything with dry soup mix. Cover and cook on high for 3-4 hours or low for 6-8 hours until steak and potatoes are tender to your liking.
