Slow Cooker Potato Soup

Ultimate Comfort: Slow Cooker Creamy Potato Soup

If you are looking for the absolute gold standard in “set-and-forget” comfort food, a classic slow-cooker potato soup is hard to beat. It requires minimal active prep, uses everyday pantry and fridge staples, and fills the house with an incredible, cozy aroma as it simmers away to rich, velvety perfection.

Ingredients (Serves 6)

  • The Base & Veggies:
    • 3 lbs Yukon Gold or Russet potatoes, peeled and diced into $\frac{1}{2}$-inch cubes (Yukon Golds provide a naturally buttery flavor and texture)
    • 1 medium yellow onion, finely diced
    • 3 cloves garlic, minced
    • 4 cups low-sodium chicken broth (or vegetable broth)
  • The Rich Dairy & Thickeners:
    • $\frac{1}{3}$ cup unsalted butter
    • $\frac{1}{3}$ cup all-purpose flour (to build a smooth roux)
    • 1.5 cups half-and-half or heavy cream (for luxurious richness)
    • $\frac{1}{2}$ cup sour cream or cream cheese (adds a wonderful tang and velvety body)
  • Seasoning & Toppings:
    • 1 tsp salt (plus more to taste)
    • $\frac{1}{2}$ tsp freshly cracked black pepper
    • 1 tsp dried chives or fresh green onions, chopped
    • 1.5 cups shredded sharp cheddar cheese
    • Crispy bacon bits (optional, for topping)

Step-by-Step Instructions

  1. Load the Slow Cooker:
    • Place your diced potatoes, chopped onion, and minced garlic into the slow cooker crock.
    • Pour in the chicken broth and season with salt and pepper. Stir once to combine.
  2. Slow Cook:
    • Cover with the lid and cook on LOW for 6 to 7 hours (or HIGH for 3 to 4 hours) until the potatoes are completely tender and easily mash with a fork.
  3. Thicken the Broth:
    • Optional texture step: If you like a thicker soup with a mix of texture, use a potato masher right inside the slow cooker to mash about half of the potatoes while leaving the rest chunky.
    • In a small saucepan over medium heat, melt the butter, then whisk in the flour for 1 minute to cook out the raw flour taste. Slowly whisk in a cup of warm liquid scooped from the slow cooker to create a smooth paste, then pour this back into the soup and stir well.
  4. Stir in the Dairy:
    • Pour in the half-and-half (or heavy cream) along with the sour cream (or cream cheese) and 1 cup of the shredded cheddar cheese. Stir thoroughly until the cheeses melt completely into the hot broth, creating a silky, creamy texture.
  5. Rest and Serve:
    • Cover and let it warm through on LOW for another 15 minutes.
    • Serve hot in warm bowls, topped generously with the remaining cheddar cheese, chives, and crispy bacon bits if desired!
Pro Tip: For an ultra-smooth, restaurant-style velvety soup, you can use an immersion blender right in the slow cooker to puree the mixture completely before stirring in the cream and cheese!
