So, let’s dive into the recipe, uncover its historical roots, and master the art of creating this delicious slow-cooker potato soup.

Historical Context

Potatoes have a fascinating history, originating in the Andes Mountains of South America over 10,000 years ago. Spanish explorers introduced potatoes to Europe in the late 16th century, where they quickly gained popularity for their hardiness and nutritional value. Potato soup variations have since appeared in cuisines worldwide.

In the United States, potato soup became especially popular during the 19th century. It was a simple and affordable dish for many American families, often made with readily available ingredients. Today, potato soup recipes range from rustic to gourmet, but they all share the same foundation: creamy potato goodness.


1. Prepare the Potatoes and Aromatics

  • Peel and dice the russet potatoes into uniform chunks for even cooking.
  • Finely chop the onion and mince the garlic cloves.

2. Combine Potatoes and Aromatics in the Slow Cooker

  • In the slow cooker, add the diced potatoes, chopped onion, minced garlic, bay leaves, dried thyme, and paprika.
  • Pour in the chicken or vegetable broth, making sure it covers the potato mixture.
  • Season with salt and pepper to taste.

3. Set the Slow Cooker

  • Cover the slow cooker and set it to cook on low for 4 to 6 hours, or until the potatoes are tender and easily mashed with a fork.

4. Make the Roux

  • In a medium saucepan, melt the unsalted butter over medium heat.
  • Once the butter is melted and foamy, whisk in the all-purpose flour to create a smooth paste, known as a roux. Continue to cook and whisk for 2-3 minutes, until it turns a light golden color.

5. Add Cream and Milk to the Roux

  • Gradually pour in the heavy cream and whole milk, whisking continuously to prevent lumps. Keep whisking until the mixture thickens and becomes smooth. This typically takes 5-7 minutes.

6. Combine Roux with Potato Mixture

  • Carefully remove the bay leaves from the slow cooker.
  • Gradually add the creamy roux mixture to the slow cooker, stirring to combine. This will thicken the soup and make it wonderfully creamy.

7. Add Cheddar Cheese and Sour Cream

  • Stir in the shredded sharp cheddar cheese until it melts into the soup, creating a cheesy delight.
  • Add the sour cream and continue to stir until fully incorporated, giving the soup a rich and luxurious texture.

8. Adjust Seasoning and Serve

  • Taste the soup and adjust the seasoning with salt and pepper as needed.
  • Ladle the rich and creamy slow-cooker potato soup into soup bowls.
  • Garnish with chopped fresh chives, if desired, for a burst of color and flavor.

9. Enjoy!

  • Serve your potato soup hot, alongside crusty bread or a fresh salad. It’s a meal on its own or a delightful appetizer. Savor each spoonful of this comforting, hearty soup.
