A super creamy cauliflower soup that is rich in flavor and full of nourishing plant-based ingredients! This soup is made with a secret pantry ingredient that makes it so creamy and adds just the right amount of protein.
I’m a lover of creamy soups and this vegan cauliflower soup is in my top faves. And if you’ve never had soup with cauliflower in it – believe me when I say it’s truly delicious and add’s the perfect touch of flavor.
One of the many reasons I love this soup is using white beans as not only protein but also a dairy replacement. When the beans are pureed with the soup is acts as a cream-base and gives this soup it’s velvety texture without using dairy. It’s a win-win situation.
This soup is extremely easy to make, consist of with 9 wholesome ingredients, and is instant pot friendly (see notes for cooking instructions).
Ingredients You’ll Need
This soup is made with a few vegetables and simple pantry ingredients. Here’s what you’ll need:
- Leeks: These are incredibly aromatic and add lots of sweet flavor!
- Yellow onions: onions will add to the taste and richness of the soup.
- Garlic cloves: fresh garlic (not garlic powder) is a must for any good soup.
- Cauliflower: the base of the soup! I love using fresh cauliflower but frozen works too.
- Vegetable broth: a high-quality, low-sodium broth!
- Thyme sprigs: fresh thyme sprigs are the perfect aromatic ingredient to infuse a ton of flavor into your soup!
- White beans: these beans have two purposes – protein and when they are pureed they are the perfect dairy replacement.
- Butter/vegan butter: use dairy-free butter, unsalted regular butter, or oil!

Creamy Cauliflower Soup (Vegan)
Ingredients
- 3 leeks, cleaned and chopped (see notes)
- 1 yellow onion, diced (small or half of large onion)
- 2 garlic cloves, chopped (large cloves or 3-4 small)
- 3 1/2 cups vegetable broth
- 2 1/2 cups chopped cauliflower
- 3/4 cups white beans, drained
- 3 fresh thyme sprigs
- salt & black pepper
Instructions
- Prepare the vegetables: First, remove the ends and outer layer of leeks. Slice length wise in half and diced into small pieces. Then rinse diced leeks in a bowl of water. Dice yellow onion, and mice garlic cloves.
- Sauté vegetables: In a large pot on low to medium heat, sauté diced leeks and onions in oil/butter for 5 minutes. Tip: always add a pinch of salt when sautéing vegetables. Each cooking process will be layered with flavor and it helps the ingredients "sweat" excess moisture.
- Add aromatics: add minced garlic and thyme sprigs to sautéed vegetables, stir for 30 seconds. Tip: This simple step releases the aromatic properties of the ingredients, which in turn makes for a more complex, fuller-flavored soup.
- Add rest of ingredients & simmer: Then add chopped cauliflower, vegetable broth, white beans, and salt & black pepper. Cover pot and let simmer for 12-15 minutes until cauliflower is soft. Use a fork to remove thyme sprigs.
- Puree soup: Then either carefully transfer to a high-powered blender or use a hand-immersion blender to puree soup until creamy and smooth.
- Taste and serve: Taste the soup before serving. Does it need more flavor? Add a pinch of salt until more flavors are drawn out. Need a little bit more of a kick? Add a pinch more of black pepper or a pinch of red pepper flakes. Serve and enjoy!

Delicious soup! I used 2 leeks instead of 3. And I used a bag of crumbled cauliflower to save time. This soup is healthy & loaded in soluble fiber… so brace yourself for bloating lol!
Thank you so much, June! Glad you enjoyed it:)
I just made this fir the second time & absolutely love it. So delicious and satisfying. Freezes well too. I didn’t have vegetable broth but chicken broth works great if you’re not vegan. Of sour cream is a great topper. Thank you for this great simple recipe.
Thank you so much, Delia! I’m so glad you love this recipe:)
So simple and so yummy. My market was out of fresh cauliflower so I used frozen and it came out perfectly. Perfect for a cold New England night! Thank you!
Yummy. I added one medium potato and half can chickpeas because I didn’t have white beans. It turned out really good!! The recipe is a keeper.
YUM! I LOVE cauliflower. Can’t wait to try.
