Slow Cooker Loaded Potato Soup

Step 1
Combine potatoes, chicken stock, onion, salt, and pepper in a slow cooker. Cook on High until potatoes are tender, about 4 hours.

Step 2
Meanwhile, place bacon in a large skillet and cook over medium-high heat, turning occasionally, until evenly browned, about 10 minutes. Drain bacon on paper towels and wipe out most of the grease from the skillet.

Step 3
Puree potatoes in the slow cooker with an immersion blender until smooth. Add 1/2 cup Cheddar cheese and 1/2 of the cooked bacon, set temperature to Low, and cook for 1 to 2 hours.

Step 4
Melt butter in the skillet over medium-low heat. Whisk in flour and stir until the mixture becomes paste-like and light golden brown, about 5 minutes. Add heavy cream and sour cream and whisk until thickened. Pour into the slow cooker and cook on Low for 1 more hour.

Step 5
Ladle into bowls and garnish with remaining bacon, remaining Cheddar, sour cream, and scallions.
