  • Cut steak into strips and place them in a mixing bowl.
  • Add cornstarch to steak and toss to coat. Place steak into the slow cooker.
  • Mix oil, ground ginger, garlic powder, soy sauce, water, and brown sugar. Pour this over steak inside slow cooker.
  • Cook on high for 3 hours or on low for 5 hours. Until steak is cooked through.
