Prepare the slow cooker: Lightly grease your slow cooker with butter or cooking spray.
Add ingredients: Place the chopped cauliflower, heavy cream, cream cheese, butter, and seasonings in the slow cooker. Pour in the chicken broth for extra moisture.
Cook on low for 3-4 hours or until the cauliflower is tender. Stir occasionally to ensure even cooking.
Add cheese: Once the cauliflower is soft, stir in shredded cheddar cheese and crumbled bacon. Let it melt into the mixture for another 15-20 minutes.
Serve: Garnish with fresh chives and extra bacon crumbles. Enjoy this creamy, cheesy, and smoky keto side dish!
