Step 1

Preheat oven to 400 degrees. Line a baking sheet with aluminum foil.

Step 2

Spread bacon in a single layer onto the prepared baking sheet. Place into oven and bake until brown and crispy, about 12-14 minutes. Let cool before crumbling; set aside.

Step 3

Line a slow cooker with aluminum foil, leaving enough to overhang to wrap the potatoes on top, and coat with nonstick spray. Place a layer of potatoes evenly into the slow cooker. Top with cheese, Ranch Seasoning and bacon, repeating 2 more times and reserving 1/2 cup cheese.

Step 4

Cover potatoes with aluminum foil. Cover and cook on low heat for 7-8 hours or high heat for 3-4 hours, or until potatoes are tender. Sprinkle with remaining 1/2 cup cheese. Cover and cook until melted, about 1-2 minutes.

Step 5

Serve immediately, garnished with chives.
