Cook bacon in a preheated oven at 400°for 12-14 minutes or until brown and crispy. Set aside then crumble when cool.

Place a crock pot liner in your slow cooker or coat with non-stick spray.

Place the chopped potatoes into the crock pot. Make sure you top each layer of potatoes with ranch dressing, cheese, and bacon. Reserve 1/2 cup of the cheese to put on top at the end.

Cover the potatoes and cook on low for about 8 hours or on high for about 3 hours.

When finished, sprinkle the potatoes with the remaining 1/2 cup of cheese. Recover for another few minutes until it melts. Top with the chives and serve.
