Slow Cooker Instructions: Brown the beef, onion, and garlic in a large skillet. Drain off the fat, and stir in the seasoning. Layer the ingredients in the Crock Pot as instructed in the recipe above. Cover and cook on LOW for 4-6 hours or on HIGH for 2-3 hours, until the potatoes are tender. Sprinkle the cheese on top and continue cooking just until the cheese melts. Sprinkle with crushed chips, crackers, or Corn Flakes, if desired (the topping won't get browned and crispy in the slow cooker, so you might prefer to omit this ingredient).
