I love a good bowl of creamy potato soup, but I don’t always love the calories and points that come with it. That’s why this Creamy Low Fat Crock Pot Cauliflower Potato Soup is such a winner. By blending cauliflower with potatoes, you still get that rich, velvety texture of classic potato soup—only lighter and healthier.
This recipe is one of my favorite slow cooker soups for busy weeknights or cozy weekends. It comes together with just a handful of simple ingredients, simmers away in the crock pot, and blends into a smooth, comforting soup that tastes indulgent but fits right into my Weight Watchers plan.
Even Rod was impressed by how satisfying this turned out, and it’s now a regular on our winter menu rotation.

Ingredients for Creamy Crock Pot Cauliflower Potato Soup
- Cauliflower – Fresh or frozen florets both work. This is the secret to keeping the soup light yet creamy.
- Potatoes – Yukon Golds are my favorite for their buttery texture, but russet or red potatoes work too. They balance the cauliflower and give the soup body.
- Garlic – Adds warmth and depth as it simmers with the vegetables.
- Chicken or vegetable broth (affiliate link) – Use whichever you prefer. I often go with low-sodium broth to better control the salt.
- Seasonings – Just salt and pepper keep things simple, though you can add thyme, bay leaf, or Italian seasoning for extra flavor.
- Parmesan cheese (optional) – A sprinkle of freshly grated Parmesan on top before serving makes it taste extra indulgent.

Step-by-Step Instructions for Crock Pot Cauliflower Potato Soup
Step 1: Prepare your vegetables.
Chop the cauliflower into florets and dice the potatoes into small cubes. Smash or mince the garlic cloves.
Step 2: Add to the slow cooker.
Place the cauliflower, potatoes, and garlic in your crock pot. Pour in the broth and season with salt and pepper. Stir to combine.

Step 3: Cook until tender.
Cover and cook on LOW for 6–8 hours, or on HIGH for 3–4 hours, until the vegetables are very soft.
Step 4: Blend until creamy.
Use an immersion blender (affiliate link) right in the slow cooker to puree the soup until smooth. (Or carefully transfer batches to a countertop blender (affiliate link) and return to the slow cooker.)
Step 5: Adjust seasoning.
Taste and add more salt and pepper if needed. Thin with extra broth if you prefer a looser consistency.
Step 6: Serve warm.
Ladle into bowls and, if desired, top with a sprinkle of freshly grated Parmesan cheese before serving.
Recipe Notes and Tips
- Cauliflower + potatoes = creamy texture. Using more cauliflower than potatoes lightens the soup while still giving it that satisfying creamy feel.
- Blending options. An immersion blender (affiliate link) makes quick work of pureeing the soup, but a countertop blender (affiliate link) will also do the job. Just blend in small batches and be careful with the hot liquid.
- Broth matters. Low-sodium broth works best so you can control the seasoning. If you want a richer flavor, swap part of the broth for chicken bone broth.
- Make it dairy-free. This soup is naturally creamy without cream or milk. If you want a little extra richness, stir in a splash of unsweetened almond milk, oat milk, or light evaporated milk.
- Flavor boosters. Try adding a bay leaf, thyme, or Italian seasoning during cooking, then remove before blending. A pinch of smoked paprika or nutmeg also complements the cauliflower.
- Optional toppings. Keep it simple with a sprinkle of Parmesan or get creative with chives, crispy bacon bits, croutons, crunchy bread crumbs or a swirl of plain Greek yogurt.
- Storage. Leftovers keep well in the refrigerator for up to 4 days and freeze beautifully for 2–3 months. Reheat gently on the stovetop or in the microwave (affiliate link), adding extra broth if needed.
Serving Suggestions
This creamy cauliflower potato soup is hearty and comforting, yet simple. To build it into a more complete meal, I like to pair it with sides that add both texture and flavor:
- A slice of crusty whole-grain bread, a wedge of cornbread, or a few whole-grain crackers are satisfying without overdoing it.
- For freshness, a crisp salad is perfect: try my Orange Spinach Salad, Weight Watchers Italian Arugula Salad, or the Simple Arugula Salad with Sunflower Seeds and Parmesan.
- If you want something heartier, I also love serving this with my Artichoke Tomato Salad—it has more substance and pairs well with the mild creaminess. Or try the Kale Salad with Apples and Dates for a mix of crunchy, sweet, and savory that complements the soup beautifully.

Was really excited to try this recipe, turned out to be gross! I don’t normally do reviews but I did with this one because of how strongly I disliked this soup. Had a strange flavor and did not taste like potato soup. I have used Cauliflower before in recipes and they have came out excellent but this one was NOT one of those. It has a strange texture and taste.
Hi Kylie, Sorry you didn’t like it. We did. Everybody’s tastes are so different!!
Garlic fell off the list of what gets added to the crock pot. Remember the garlic!
I am glad posted points plus. I love that program and I lost 30lbs. It is nice when people post both:)! The soup was so good! Having left overs for lunch right now.
Thanks Blaire!
Hi martha: Are you aware that WW is now using a different way to track Points. They are now Smart Points and use different nutritional values – Calories, saturated fat, sugars, protein. I mention it because I enjoy your site and thought you should know when giving out Points values.
Hi Suzanne, Yes, I’m aware that WW is now using SmartPoints instead of PointsPlus. I’ll be posting about my first 3 weeks using the new system tomorrow! I was given the opportunity to take a sneak-peek, but am sworn to silence until tomorrow at 10, when WW officially unveils the new plan. I’ll begin including SmartPoints and their associated nutritional values with all new recipes effective immediately but it will take some time to go back and update the old ones.
