Cream-less cauliflower soup

This healthy cauliflower soup is perfect for when you’re craving something warm, and comforting.

The natural texture of cooked cauliflower blends into a thick, silky, nutrient-rich soup. No cream, milk, potatoes, or thickeners are required.

You can serve it as a first course for dinner or with a salad or sandwich for lunch.

Ingredients and substitution suggestions

You only need a few basic ingredients to make this simple cauliflower soup:

  • Cauliflower – One large head of cauliflower, approximately 2 1/2 pounds (1 Kg).
  • Olive oil – Or your preferred cooking oil.
  • Onion – If you prefer a milder flavor, leeks or shallots are a wonderful substitute for regular onions.
  • Garlic – Fresh garlic.
  • Fresh thyme – Adds flavor! Feel free to experiment with other herbs, fresh or dried.
  • Low-sodium vegetable stock – I used my homemade vegetable stock powder. It can be replaced with low-sodium chicken stock.
  • Seasonings – Salt + freshly ground black pepper.

How to make a flavorful cauliflower soup

To make this healthy soup, simply:

  1. Sautée the garlic and onion until softened.
  2. Add the cauliflower, vegetable stock,  and thyme sprigs.
  3. Let everything simmer until the cauliflower is tender.
  4. Puree the ingredients right in the pot with an immersion blender, or transfer the soup to a traditional blender in batches and blend until it’s smooth.
  5. Season with salt and pepper.
  6. Add the toppings and done! This velvety smooth and SO delicious soup will be ready to serve.

If your soup is too thick after blending, thin it out with some more vegetable stock. If it’s too thin, bring it back to a simmer and cook until it has reached your desired consistency.

Instant Pot cauliflower soup

You can easily make this soup in the instant pot.

  1. Add the cauliflower florets, garlic, onion, vegetable stock, fresh thyme, salt, and pepper to the Instant Pot.
  2. Cook on high pressure for 8 minutes.
  3. Quick-release the pressure. Open the pot and use an immersion blender to blend the soup or put the soup in a blender until smooth.

Topping suggestions

Toppings and garnishes are the perfect way to customize your soup.

I topped my bowls with roasted chickpeas, chopped fresh thyme, and a drizzle of extra virgin olive oil to finish it off. Roasted chickpeas add texture and crunch.

Toasted nuts/seeds, croutons, chives, parsley, truffle oil,….are also great additions. If you want to treat yourself, stir in a dollop of cream or Greek yogurt.

How do you make roasted chickpeas

Toss the chickpeas in a simple mixture of salt, paprika, chili powder, and cumin, and roast them for 25 minutes. The result is a tender chickpea with a slightly crispy edge and a spicy-smoky flavor.

I advise you to make a double batch of these chickpeas because they’re also a fabulous snack.

Customize it!

  • Make it spicy: Add a generous sprinkle of crushed red pepper flakes to this soup before serving to give it a bit of a kick.
  • Fresh herbs:  Use rosemary, sage, or oregano instead of thyme.
  • Add in some extra veggies: Feel free to toss in a handful of chopped broccoli along with the cauliflower.  
  • Add proteins – Cooked shrimp pairs wonderfully with this soup!
  • Make it heartier – I love to stir in a couple of spoonfuls of cooked basmati rice, quinoa, white beans, or chickpeas.
  • Make it “cheesy”– Blend in 1/3 cup of nutritional yeast when you blend the soup.

How to make ahead, store and freeze

Make-ahead – Cauliflower soup can be made in advance and reheated when needed.

How to store – Allow soup to cool to room temperature. Store in an airtight container in the fridge for up to four days. Reheat the soup on the stovetop or in the microwave, adding a little water to adjust the consistency if it’s thickened substantially.

How to freeze – Since this cauliflower soup doesn’t contain any cream, it freezes exceptionally well. Let it cool, transfer it to an airtight container, and freeze it for up to three months. The night before you want to enjoy it, transfer the container to the refrigerator to slowly thaw overnight, then reheat the soup in a saucepan over medium heat.
