Preheat oven to 400°F. Line a baking sheet with foil and arrange the bacon on top. Bake for 15-20 minutes, or until crispy. Once done, chop bacon and set aside.
While the bacon cooks, wash, peel, and dice the potatoes. Dice the onions and mince the garlic.
Add potatoes, onions, garlic, chicken broth, black pepper, and thyme to your Crock-Pot. Stir in half of the chopped bacon. Cover and cook on low for 6-8 hours, or on high for 4-5 hours, until potatoes are fork-tender.
Once potatoes are done, set the Crock-Pot to warm. Add heavy cream, half of the cheddar cheese, and the cream cheese. Cover for 10 minutes to allow everything to melt. Stir, taste, and adjust seasonings as needed.
Serve topped with extra cheddar cheese, bacon, and chives.
