  6. Serve the soup in bowls with crackers or croutons on the side.  


  • You can replace the water with 5 cups of chicken stock (low-sodium or unsalted) and omit the bouillon or base.
  • To freeze potato soup, cool it and transfer it to a zip-close bag or freezer container. Store in the freezer for up to 3 months. To reheat, simmer gently. If the defrosted soup appears watery, add a bit of cream or evaporated milk.
  • Low starch potatoes, such as Red Bliss or new potatoes, hold up better in the slow cooker than the higher starch baking potatoes. Or use ​moderate starch potatoes, like Yukon Gold.

Recipe Variations

  • Cook 4 to 6 strips of bacon. Drain and crumble. Add the bacon to the soup when you add the milk.
  • Dice about 6 ounces of smoked sausage. Brown it in a small amount of oil in a skillet and add to the soup.
  • Add about 1/2 cup of diced cooked ham to the soup mixture along with the vegetables.
  • Sprinkle servings with fresh chopped parsley, green onion tops, or chives.
  • Add 1 to 2 cups of shredded cheddar cheese along with the milk, or top servings with shredded cheese.
  • Replace the chicken broth with vegetable broth for a vegetarian potato soup.
  • Add chopped spinach or kale to the soup for additional color and nutrients.
