    I have fond memories of my grandma making this easy 4-ingredient potato soup recipe when I was a teenager. Thanks, Grandma! 🥰 I have always been under the impression she got it from her mother who was of German heritage, but wherever she got it, it's a classic!

    She made the original recipe on the stovetop, but I made it work in the crockpot (affiliate)as well. This is one of my all-time favorite soup recipes for a cold day in the fall and winter months! If you love soup, be sure to check out the soup and chili page for even more delicious recipes.

    I serve this creamy soup with a simple roll or salad when I am in a time crunch or have very little on hand. However,  when I want to earn real mom points I serve it with these BELT sandwiches… it’s a BLT + a fried egg. 😋

    🥇 Why It’s Great!

    • With only 4 ingredients it's a great way to stretch your grocery budget.
    • It’s an easy, homemade soup with only 15 minutes of prep time. 
    • It is made without flour so it is naturally gluten-free.
    • It can be made in either a crockpot or a large pot (or Dutch oven) on the stovetop.
    • Awesome recipe to serve to a crowd of people! See the section below on tips for serving a crowd.
    Ingredients for Easy 4-Ingredient Potato Soup on the counter.
    These simple ingredients get transformed into an easy dinner in either the slow cooker or on the stovetop.

    🥔 Potato soup ingredients

    Potatoes: The best potatoes to use when making potato soup are russet potatoes. Yukon gold potatoes or red potatoes will work as well, but the texture will be different.
    Onion: Yellow onion is the best for this although white onion will work as well. Stay away from red onions because they will turn the soup a color that isn’t very attractive.
    Milk: Any milk you have on hand or half and half will work, although my favorites are 2% milk or whole milk.
    Butter: Adds richness to the soup. Don’t skip this ingredient.

    🥓 Best toppings for potato soup

    Optional: These are my favorite toppings.
    Bacon: A couple strips of cooked bacon are all that is needed to really make this soup something special. Bake the bacon in the oven, microwave it, or fry it on the stove top while you prep the potatoes. Then when it is time to serve the bacon is ready.
    Cheese: Sharp cheddar cheese is my favorite but any cheddar will do.
    Green onions: Just a quick slice and you have the perfect touch of freshness.

    🔪 How to make potato soup

    How to make potato soup in the crock pot instructions.
    The key to creamy potato soup is to cook the potatoes until they are falling apart. Then use an immersion blender until the soup reaches the consistency you prefer.

    Slow cooker instructions

    Begin by chopping the potatoes and yellow onions. Then add the diced potatoes and onions to the slow cooker along with the water. Cook on high for 3-4 hours or low for 6-8 hours.

    Once the potato chunks are falling apart, remove 1 cup of the cooking water. Add in the butter along with 1 cup of the milk, then carefully put in the immersion blender and blend until creamy and smooth.

    For a thicker soup leave as is or for a thinner creamy texture add in additional milk if necessary to reach the desired consistency.

    In our opinion the best potato soup recipe has minimal ingredients and is served with a smooth texture free of potato chunks. If you want more of a chunky soup or don't have an immersion blender on hand, feel free to use a potato masher. The texture won't be exactly the same, but it will still be a delicious bowl of soup.

    Season with salt and black pepper to taste. Serve as is or with the optional toppings. If you opt for crispy bacon bits as a topping, try baking your bacon according to this recipe. No more bacon grease on the stovetop! It's life changing!

    Stovetop instructions

    After chopping the potatoes and onions, add the raw potatoes and onions to a large pot or large dutch oven along with the water. Turn the pot on to medium-high heat and cook until the potatoes are falling apart. Continue preparing according to the slow cooker instructions. Once the soup is smooth, continue warming over medium heat until hot.

    👨‍👩‍👧‍👦 For a Crowd

    The best way to do this for a crowd is to have several slow cookers at your disposal. When serving a crowd I like to build in a little flex time by starting the slow cookers an hour or two earlier than usual. Once the soup has been blended, then the slow cookers can be set to “warm” for a couple hours. Stir the soup occasionally or it will form a skin on the side of the crock.

    Note:
    A 6 qt. slow cooker should fit 1 ½ recipes and a double batch will fit in a 7 qt. slow cooker. It may take several more hours to cook a double recipe in 1 slow cooker.

    This is an easy soup to serve to crowd. All you need are a few extra crockpots.

    🥣 Variations

    • Loaded Baked Potato Soup: Use salty bacon, cheddar cheese, chives and a dollop of sour cream for a fully loaded potato flavor.
    • Use up leftover ham for a protein boost.
    • Play around with different seasoning. A little bit of thyme or even cajun seasoning would be a fun twist.
    • For a lower calorie version use skim milk and skip the toppings.
    • For a richer soup, use heavy cream in place of the milk.

    🙋 Questions and Answers

    Can I potato soup be made ahead of time?

    Potato soup can be made a few hours in advance. However, it will thicken as it cools so be sure to have some extra milk on hand to thin as necessary.

    How to reheat potato soup?

    Can I freeze potato soup?

    I do not recommend freezing potato soup. Once frozen it can develop a grainy texture that is quite unpleasant.

    👨🏼‍🍳 Tips & Tricks

    • Test one of the larger potato pieces before blending. When you touch it with a fork it should break apart effortlessly. It should be super soft!
    • Don’t turn on the immersion blender until you have put at least 1 cup of milk or the potatoes will become gummy.
