Preparing mashed potato soup requires a selection of simple, wholesome ingredients:

  • Butter: Used to start the base of the soup and add richness.
  • All-Purpose Flour: Helps thicken the soup, giving it a creamy texture.
  • Salt and Ground Pepper: Essential for seasoning and enhancing all the flavors.
  • Chicken Broth: The liquid base that adds depth and warmth to the soup.
  • Milk: Increases the creaminess and smoothness of the soup.
  • Prepared Mashed Potatoes: The star ingredient that thickens the soup and provides its distinct potato flavor.
  • Shredded Cheddar Cheese: Melts into the soup, adding a delicious cheesy taste.

Steps for Making Mashed Potato Soup

Follow these steps to create a comforting and creamy bowl of mashed potato soup:

  1. Melt the Butter:
    • Begin by melting butter in a large pot over medium heat. This will form the foundation of your roux, crucial for a rich and thick soup.
  2. Prepare the Roux:
    • Whisk in flour, salt, and pepper with the melted butter. Cook until the mixture is well combined and starts to turn golden, ensuring your soup base will be smooth and thick.
  3. Gradually Add Liquids:
    • Slowly incorporate chicken broth and milk while continuously whisking. This gradual addition prevents lumps and integrates the roux smoothly with the liquids, setting the stage for a creamy soup.
  4. Add the Mashed Potatoes:
    • Stir in the mashed potatoes until completely blended with the liquid. This will thicken the soup and enhance its potato flavor.
  5. Mix in the Cheese:
    • Add shredded cheddar cheese to the pot, stirring until it’s melted and the soup achieves a creamy consistency.
  6. Simmer to Finish:
    • Let the soup simmer for about 10-15 minutes or until it thickens to your liking. Keep stirring occasionally to prevent the ingredients from sticking to the bottom and to ensure even cooking.

This method produces a rich and hearty mashed potato soup, perfect for chilly evenings or as a satisfying meal any time of the day. Serve hot and enjoy the creamy texture and comforting flavors.
