Ingredients
- Medium Sweet Potatoes – One of the most affordable vegetables year-round. Buy in bulk for even better savings.
- Vegetable Broth – Feel free to also use chicken broth
- Butter – We used unsalted butter

How to Make Crock Pot Sweet Potato Soup
This recipe works best in a slow cooker with at least a 4.5-quart capacity.
Step 1 – Add ingredients to slow Cooker – Place the diced sweet potatoes, butter, celery, onion, seasonings, and broth in the crock pot.
Step 2 – Cook – Cover and cook on low for 6-8 hours or high for 3-4 hours.
Step 3 – Blend the Potatoes – Once cooked and the potatoes are tender by piercing with a fork. We purée the soup using an immersion blender or carefully spoon the contents of your crockpot into your blender to purée. Return to the crock pot and stir in the coconut milk. If using a stand blender instead of an immersion blender, work in small batches and never fill it more than halfway — hot soup can splatter and cause burns if the blender is overfilled.
Step 4 – Continue Cooking – Cover and cook on low for 10-15 minutes until the coconut milk is combined and heated through.
Step 5 – Serve and Enjoy – Serve warm and enjoy!
Tips for the Best Sweet Potato Soup
- Instant Pot – You can also make this in the Instant Pot.
- Stovetop – Make this soup in a Dutch oven on the stove top. It would take about 30 minutes to bring to a boil. This makes for a quick weeknight meal.
- Cutting Sweet Potatoes – So the sweet potatoes cook evenly, cut them about the same size.
- Blending Sweet Potatoes – You can use a immersion blender or a food processor.
- Coconut Milk – When adding in the coconut milk, we recommend adding it towards the end of cooking time. This prevents it from curdling in the soup.
- Liquid – You want to add just enough liquid to cover the vegetables.
- Adding Seasoning – When adding in the seasoning, we like to add in when placing the sweet potatoes in. This allows for the ingredients to really cook all together.
- Onions and Celery – Since everything gets blended smooth at the end, there’s no need to dice the onion and celery precisely — rough chopping works just as well and saves you time.
Variations and Add-Ins
- Coconut Milk – You can use additional broth if you do not like coconut milk in this recipe.
- Smokey Flavor – If you like a more smokey flavor, add some chipotle pepper.
- Seasoning – This recipe calls for simple seasoning but feel free to add in other options. Here are some suggestions, smoked paprika, ground nutmeg, cinnamon, or fresh herbs.
- Add in Meats – Feel free to add in some shredded chicken, ground beef or pork to this soup.
- Chicken Stock – Instead of vegetable broth you can easily use chicken stock or chicken broth.
- Heavy Cream – You can add in heavy cream instead of coconut milk. Just make sure you still add towards the end of cooking time.
Make This Soup Work for Busy Nights
- Prep everything the night before and store in the fridge.
