“Fantastic,” as described by a reader, this slow cooker cauliflower soup has nearly no prep time and is naturally creamy and vegan, thanks to cauliflower and cashews! We love to top it with crispy spiced chickpeas to amp up the protein (and deliciousness).
Pairs well with Air Fryer Brussels Sprouts (with hot honey, yum!) and Sweet Potato Gnocchi.

Is there anything cauliflower can’t become? This velvety smooth cauliflower soup tastes like a creamy potato soup (but with fewer carbs). Unlike in my roasted cauliflower soup where caramelized edges bring big flavor, we’re cooking this one low and slow in the slow cooker.
The long cooking time means the veggies become tender, and flavors blend perfectly, making for the most delicious (and hands-off) dinner!

“Honestly I was skeptical. I really thought as simple as this recipe was, that it would be bland. But it was delicious, I wouldn’t change anything. ” —Sara

the creamy secret
Now, you can make a pretty good cauliflower soup with cauliflower alone, but cashews make it really good. Cashews make this slow cooker cauliflower soup feel full and creamy (while keeping the recipe totally plant-based!)


Freezer Meal Prep
This soup is amazing as a freezer meal prep dinner! Add all of the soup ingredients to a freezer-safe bag and store frozen for up to 3 months. When ready to enjoy, add it all to a slow cooker with vegetable broth and cook (starting at Step 1 of the recipe).

P.S. If you loved this recipe, try my Vegan Corn Chowder or Broccoli Soup With Cashews next! Or for another creamy option, try this Cauliflower Leek Soup!

Slow Cooker Vegan Cauliflower Soup (With Cashews)
Ingredients
Cauliflower Soup
- 1 medium head cauliflower, cut into florets
- ½ medium yellow onion, chopped
- 1 cup cashews, 125 g
- 4 cups vegetable broth, 1 L
- ½ tsp salt
Crispy Chickpeas
- 1 15-oz can chickpeas, drained and patted dry, 425 g
- 1 Tbsp olive oil, 15 mL
- 1 tsp smoked paprika
- ½ tsp cumin
- ¼ tsp salt
Instructions
Cauliflower Soup
- Cook: Roughly chop cauliflower and onion. Add to slow cooker along with cashews and broth. Submerge the cauliflower and cashews under the broth as much as possible, then cover and cook until cauliflower is tender (high for 3 to 4 hours, low for 6 to 8).

- Blend: When cauliflower is tender, puree the mixture until smooth using either a handheld immersion blender or by carefully transferring to a countertop blender.

Chickpea Topping
- Preheat oven to 400°F (204°C). Toss chickpeas with oil. Spread onto a baking sheet and bake for 20 minutes, or until crispy. While still hot, toss chickpeas with spices and salt. Serve warm over the soup.

Soup, Salad, and sandwich!
No matter what you’re feeling, we’ve got recipe pairing options to make this cozy soup a full meal.
- The Best Avocado Sandwich: This gem is ready in just 15 minutes, and its cool filling is a nice contrast to the warm cauliflower soup.
- Naan Bread: With cauliflower soup being so thick, naan bread is perfect for dipping in it.
- Vegetarian Caesar Salad: I just love a good Caesar salad and soup moment, and this one delivers!

Hi! Should I use roasted or raw cashews? Thank you 🙏
Both work!
This is absolutely delicious – and such a simple recipe. I made it in the stovetop as I don’t have a slow cooker. I also added some roasted garlic, personal preference.
Was excellent. The onions really sweetened the soup. I’m thinking you could do Broccoli this way too.
What type of cashews did you use? Raw? Roasted? And if roasted, salted? Lightly salted or no salt?
Typically raw, but roasted also works! If you use salted, just reduce the added salt 🙂
I made this with 2 lb of frozen cauli and it turned out great. Like really great. Thanks for sharing it.
Do you use raw or roasted cashews?
Either! They both work well 🙂
