🛒Ingredients
This Moroccan-inspired cauliflower soup is full of warm spices, like cinnamon, cumin and coriander. It's flavoured with harissa chili paste, which adds a little heat.
You'll also need a head of cauliflower, vegetable broth and flaked almonds. Almonds help to thicken the soup, adding body and a rich flavour. You'll find a complete list of ingredients with amounts in the recipe card below.
What is harissa? Where can I find harissa in the supermarket?
Harissa is a vegan red chile paste that originates in North Africa. It’s made by combining hot red chili peppers (sometimes smoked), red bell peppers, garlic, olive oil and spices. Read more about it here.
While it has an intense bright colour, it’s not as spicy as it appears. Store-bought harissa paste is available in both regular or mild intensities, depending on your tastes. You can find harissa paste in glass jars in the spice aisle or the international food section of your supermarket or you can order it from Amazon.
While I'm using it to add flavour to soup today, I also find it a great way to spice up chicken, as I did in this convenient Harissa Chicken Sheet Pan Supper. It's also delicious on burgers! Try these Open Face Harissa Chicken Burgers with Yogurt Sauce for a flavour change!
If you don't have harissa paste, you can substitute another hot pepper sauce in this recipe.
🥄 Instructions
- Cut a head of cauliflower into florets and add to it the bowl of your slow cooker along with vegetable broth, toasted sliced almonds, cilantro, harissa and spices.
- Cover and let it simmer for 3 hours or so, then purée it right in the bowl with an immersion blender or transfer it to a blender.
- Ladle it into bowls, and have fun garnishing it with more toasted almonds and minced cilantro. Add a tiny dab of extra harissa if you like your food hot and spicy!
❤️ Can I make this North African soup on the stove top?
Absolutely. Use a heavy-bottomed pot and follow the recipe directions. Bring it to a boil, then simmer for 45 minutes or until cauliflower is very tender. Purée in a blender or with an immersion blender, garnish and serve.
🍽 Serving suggestions
I like to serve this Moroccan harissa soup with these Super Seedy Snack Crackers, or toasted Mini Keto Buns and this Greek Salad (with or without the chicken). A cozy quilt and a warm fire are great additions, too!

Hi Elaine- sounds so yummy and easy! We have the Harissa spice from your Harissa chicken recipe. Can I substitute that for the paste? And in what amount?
Flavour & Savour
Hi Laurie,
I think you could do this successfully. The Harissa Spice Mix also contains chili flakes, coriander and cumin, so I would eliminate those spices from my recipe and use the spice mix instead. My advice would be to start with a teaspoon. Then you can always add more once the soup has simmered. Keep on tasting until it tastes good to you! Let me know how it turns out!
Laurie
Thank you- I’m making it today- there were such amazing cauliflowers at the markets last weekend!
Terri Gilson
Your photos are stunning and make this soup look super cozy and delicious! My daughter and I are sort of spice crazy so I'm sure we'd love harissa (we've never tried it) but definitely will now!

Thanks so much, Terri! Harissa comes in different spice intensities, (mild, medium, etc.) It just adds a little heat and some interest to a dish. We really like it. Thanks for commenting!

This looks like a beautiful soup, Elaine. I'm adding it to my soup repertoire for when it starts getting cold here in Hong Kong (we have a few months yet...). 🙂
