Ingredients

  • 3 pounds diced potatoes 1/2" cubed pieces
  • 6 cups chicken broth (reserve 1 cup)

Potato Soup Mix Recipe (Seasoning Blend)

  • 6 tablespoons corn starch
  • 1/4 teaspoon cajun seasoning
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1/2 teaspoon ground black pepper
  • 1/2 teaspoon salt

Instructions

  • Dice the Potatoes
    Start by dicing 3 pounds of potatoes into ½-inch cubes. Add them directly to the bowl of your slow cooker.
  • Add the Chicken Broth
    Pour in 5 cups of the chicken broth over the potatoes. Set aside the remaining 1 cup of broth for later.
  • Slow Cook It
    Cover and cook the potatoes:
    On LOW for 7½ hours
    Or on HIGH for 3½ hours. Let the potatoes get perfectly soft and tender.
  • Mix the Seasoning Blend
    In a small bowl, whisk together the Potato Soup Mix Seasoning Blend:
    6 tablespoons cornstarch
    ¼ teaspoon Cajun seasoning
    1 teaspoon onion powder
    1 teaspoon garlic powder
    ½ teaspoon black pepper
    ½ teaspoon salt
    Whisk this seasoning blend into the reserved 1 cup of chicken broth until smooth and lump-free.
  • Thicken the Soup
    Pour the seasoned broth mixture into the hot soup while stirring. Cover and cook for an additional 30 minutes. This thickens the soup and brings everything together.
  • Blend or Leave Chunky
    For a silky texture, use an immersion blender right in the slow cooker to blend the soup to your desired consistency. Or leave it chunky for those dreamy, soft bites of potato.

Notes

Optional Toppings (Highly Recommended!):
  • Crispy chopped bacon
