Here is my favorite crockpot potato soup recipe, with tender potatoes, creamy broth, crispy bacon bits, and plenty of cheese that makes it the perfect comfort food for any day of the week.
This potato soup is what I make whenever someone in my family is feeling under the weather or when we need something warm and filling. I love that I can just throw everything in the crockpot in the morning and come home to the most amazing smell. Plus, there’s always enough for leftovers the next day!
Why You’ll Love This Potato Soup
- Set-it-and-forget-it convenience – Just toss everything in your crockpot and let it simmer away while you handle your day – no stirring or babysitting required.
- Rich and creamy comfort – The combination of heavy cream and sour cream creates that restaurant-quality texture that makes every spoonful feel like a warm hug.
- Simple pantry ingredients – You probably have most of these basics on hand already, making this an easy go-to recipe when you need something satisfying.
- Perfect for meal prep – This recipe makes plenty of servings and tastes even better the next day, so you can enjoy leftovers all week long.
- Naturally gluten-free – Using xanthan gum instead of flour means everyone at the table can enjoy this creamy soup without worry.
What Kind of Potatoes Should I Use?
Russet potatoes are perfect for this soup because they break down nicely as they cook, creating that thick, creamy texture you want. You could also use Yukon Gold potatoes if that’s what you have on hand – they’ll give you a slightly creamier result and hold their shape a bit better. Avoid waxy potatoes like red potatoes or fingerlings since they won’t break down as well and might leave you with chunks instead of that smooth, comforting soup base. Make sure to peel and dice your potatoes into similar-sized pieces so they cook evenly in the crockpot.
Options for Substitutions
This comforting potato soup is pretty forgiving when it comes to swaps:
- Russet potatoes: Yukon gold potatoes work great too and will give you a creamier texture. Red potatoes can work, but they hold their shape more, so you’ll get a chunkier soup.
- Chicken broth: Vegetable broth is a perfect substitute if you want to keep it vegetarian, or you can use beef broth for a richer flavor.
- Heavy cream: You can use half-and-half for a lighter version, or even whole milk, though the soup won’t be quite as rich. For dairy-free, try coconut cream or cashew cream.
- Sour cream: Greek yogurt works as a substitute, but add it at the very end and don’t let it boil or it might curdle. Cream cheese (about 2-3 tablespoons) also works well.
- Xanthan gum: If you don’t have xanthan gum, you can thicken the soup by mashing some of the cooked potatoes against the side of the crockpot, or mix 2 tablespoons flour with cold water to make a slurry.
- Butter: Olive oil works fine for sautéing the onions, though you’ll miss that rich buttery flavor. For dairy-free, use vegan butter or more olive oil.
Watch Out for These Mistakes While Cooking
The biggest mistake when making crockpot potato soup is adding the dairy ingredients too early, which can cause the cream and sour cream to curdle and separate during the long cooking process – always stir these in during the last 30 minutes of cooking.
Another common error is not cutting your potatoes into uniform pieces, as different sizes will cook at different rates and leave you with some mushy potatoes and others that are still firm.
When adding the xanthan gum, sprinkle it slowly while whisking constantly to avoid creating lumps that won’t dissolve, and remember that a little goes a long way with this thickener.
For the creamiest texture, use an immersion blender to partially blend the soup, leaving some potato chunks for texture, and always taste and adjust your seasonings at the end since the flavors concentrate during the slow cooking process.
What to Serve With Potato Soup?
This creamy potato soup is perfect with some crusty bread rolls or a warm baguette for dipping and soaking up all that rich, comforting broth. I love serving it alongside a simple side salad with mixed greens and a light vinaigrette to balance out the richness of the soup. For a heartier meal, try pairing it with a ham and cheese sandwich or even some crispy bacon crumbled on top of the soup itself. You can also serve it with some buttery cornbread or dinner rolls if you want to make it feel like a complete, cozy meal.
Storage Instructions
Refrigerate: This creamy potato soup keeps really well in the fridge for up to 4 days in an airtight container. I actually think it tastes even better the next day after all the flavors have had time to meld together. Just give it a good stir before serving since it might separate a little.
Freeze: You can freeze this soup for up to 3 months, but keep in mind that cream-based soups sometimes get a bit grainy after freezing. I like to freeze it in individual portions using freezer bags laid flat – it saves space and thaws faster when you’re ready for a quick meal.
Warm Up: Heat the soup gently on the stovetop over medium-low heat, stirring frequently to prevent sticking. If it seems too thick after reheating, just add a splash of chicken broth or milk to thin it out. The microwave works too, but use 50% power and stir every minute to keep it from getting lumpy.

- Carbohydrates: 210-240 g
Ingredients
- 5 large russet potatoes, peeled and chopped
- 1 small onion, chopped
- 4 cups chicken stock
- 4 tbsp butter
- 1 tsp finely minced garlic
- 1 tsp salt
- 1 tsp ground black pepper
- 1 cup heavy whipping cream
- 1/3 cup sour cream
- 1 tbsp xanthan gum
Step 1: Prepare and Load Ingredients into the Slow Cooker
- 5 large russet potatoes, peeled and chopped
- 1 small onion, chopped
- 4 cups chicken stock
- 4 tbsp butter
- 1 tsp finely minced garlic
- 1 tsp salt
- 1 tsp ground black pepper
Peel and chop the russet potatoes, and chop the onion.
Add the chopped potatoes and onion to your slow cooker along with the chicken stock, butter, minced garlic, salt, and ground black pepper.
Give it a gentle stir so the ingredients are evenly distributed.
Step 2: Cook the Soup Base
Cover the slow cooker and cook the soup mixture on low for 4 to 6 hours, or on high for 3 to 4 hours, until the potatoes are very soft and easy to mash.
I like to check the potatoes at the earliest suggested time—they should be fork tender and almost falling apart.
Stir occasionally if you can.
Step 3: Prepare the Cream Mixture
- 1 cup heavy whipping cream
- 1/3 cup sour cream
- 1 tbsp xanthan gum
While the soup is nearing the end of its cooking time, prepare the thickening mixture.
About 30 to 60 minutes before the soup is done, whisk together the heavy whipping cream, sour cream, and xanthan gum in a small mixing bowl until totally smooth and thick.
This will help the soup achieve a creamy, luscious texture.
Step 4: Finish and Thicken the Soup

Stir the thickened cream mixture (from Step 3) into the slow cooker with the potato soup.
Switch the slow cooker to high (if it isn’t already), and cook for an additional 20 to 30 minutes so the soup thickens slightly and becomes extra creamy.
Stir occasionally to ensure even distribution.
For a silkier finish, I sometimes use an immersion blender for just a few pulses to partially blend the soup, but this is optional.
