This cauliflower potato soup is incredibly creamy, cozy, healthy and totally vegan but also cheesy thanks to the tasty magic of nutritional yeast. No cream, no dairy, just pure deliciousness! An easy weeknight meal.
Cauliflower Potato Soup
Rich and creamy but totally dairy free made with healthy good for you ingredients, this is the ultimate vegan cauliflower soup to cozy up with all winter long. You start by sautéing aromatics to create layers of flavor, then simmer the cauliflower and potatoes with cashews and herbs before blending everything together into a blissful savory puree. No roasting the florets required. Sprinkle with crispy bread crumbs for the perfect balance of textures.
- The Cauliflower – Grab the largest cauliflower head at the market, rinse well and cut into florets. This is not the place for the pretty purple heirloom varieties. (Yes you can use a bag of frozen florets if you must).
- Golden Potatoes – Yes you can leave the skins on, just make sure to scrub and rinse them well before adding to the soup. It’s important to use a golden waxy potato with thin skin. Not only will this cut down on prep time and eliminate waste, there’s also lots of fiber and other nutrients in the skins. (If using any other potato varieties like Russets make sure to peel them first, or the color of your soup will turn brownish gray).
- Nutritional Yeast – A superfood, and because it makes everything even more delicious + it’s loaded with B vitamins, a complete protein with a savory cheesy flavor. To be used in lieu of a parmesan rind and simply to add umami flavor to any dish, in other words: sprinkle over everything like pixie dust! Choose organic, non-fortified nooch whenever possible.
- Lemon – Finishing the soup with a fresh squeeze of lemon will brighten it up but also bring out the flavor of the cauliflower.
- Toppings – Fresh herbs, drizzle of sun dried tomato pesto, toasted pine nuts, chive pesto, rosemary oil, roasted broccoli florets, garlic bruschetta.
Tips + FAQ
- Counter top blender vs immersion blender – Since this soup has different size vegetables and nuts, you will achieve the creamiest most luscious puree in a standing counter top blender such as the Vitamix. The immersion blender will leave you with a grainy texture, so you’ll want to avoid using it here if possible. Is is best used for recipes where only partial blending is needed or a simple tomato soup.
- Thickener – This soup has the absolute perfect texture so there’s no need to thicken it with anything at all. Both the potatoes and the cashews do an amazing job here while keeping the soup silky (not gummy), healthy and also gluten free.
- Water vs Vegetable Stock – When we simmer vegetables and aromatics together we are technically making stock, so there’s no reason to use store bought stock here. Use water, your soup won’t be bland, there’s so much delicious beautiful flavor here. If you want to be a little extra just add more nutritional yeast or mix in a tablespoon of white miso paste at the blending stage.
- Substitutions – Instead of a yellow onion you can use a medium leek, white + pale green parts only or the color of the soup will turn brownish during blending. (save the dark green tops for later.
- On Storage – The soup keeps well in the fridge up to 5 days and can be frozen (without the toppings) for 4 months.
