Easy cauliflower soup is made with minimal ingredients but loaded with flavor. This vegan cauliflower soup is comfort food in every bite! Thick, healthy cauliflower soups offer tasty, healthy, low-carb substitutes for potato soup recipes.
Winter, spring, summer, and fall — you can find me eating the best cauliflower soup ever! I love eating it slowly; trying to savor the moments. Like I’m eating it up with a spoon… which I can accurately say I’m doing quite literally.
If you’re like me, you’re looking for opportunities to serve yummy plant-based soup recipes all year long! That’s because they’re so easy to make, delicious, and filling!
Cauliflower is going through a Forrest Gump sort of revival right now — you can use it with mashed potatoes, pizza, served as an appetizer like cauliflower buffalo wings, and you can even make cauliflower steaks. I’m not kidding ya!
I just happen to like it with this thick and creamy soup. It’s filling, nutritious, and not too hard on the calorie checkbook. You know, that mysterious place where you try to balance calories spent vs. calories taken in? Soup is a perfect way to become a caloric CPA!

Here’s more on how to cut cauliflower into florets.
Quick Fix Tip
Substitute frozen cauliflower florets to make this recipe even faster.
Make the Broth
- Heat the oil in a large pot over medium heat.
- Add the onion, celery, and carrots. Sauté until the vegetables are tender, about 10 to 15 minutes.
- Add garlic and cook for about a minute longer.
Cook the Cauliflower
- Add the water, bouillon, wine, nutritional yeast flakes, cashews, and chopped cauliflower florets and pieces.
- Bring this to a boil, then reduce to a simmer. Simmer for 20 minutes until cauliflower is tender.
- Remove from heat and let cool slightly. Use tongs to remove half of the broccoli florets from the pot.
Blend the Soup
- Remove the center cap from your blender lid. Fill the blender only halfway.
- Secure the lid on the blender and top with a kitchen towel. Blend on low speed for a few seconds, then slowly increase speed to create a creamy soup.
- Transfer to a bowl. then repeat with the remaining ingredients from the pan. Add about 3/4 of the reserved broccoli florets to the pureed soup, leaving some to place as a topping.
Marly’s Tips
Never overfill a blender with hot liquid because the steam can build up pressure as it blends. It’s better and safer to work in batches when you’re blending a hot soup.
Serving Suggestions
To serve, season the soup with salt and pepper to taste.
Serve this simple cauliflower soup with tasty toppings like roasted cauliflower florets, croutons, air fryer chickpeas, tempeh bacon pieces, and/or sriracha. These vegan low-carb cheez-its are a nice touch, too.
Storage Tips
Store cooled soup in an airtight container. It will keep in the fridge for up to 5 days or in the freezer for up to 2 months.
Cauliflower is Healthy
Did you know cauliflower is healthy? That’s because it’s a cruciferous vegetable. That means it’s related to broccoli and kale, and I don’t have to tell you how healthy those are!
Cauliflower is a low-calorie vegetable that’s a nutritional superstar that you can include in your diet every day!
However, cauliflower soup recipes are often made with cow dairy and sometimes even ingredients like bacon. This vegan cauliflower soup is completely plant-based and delicious!

Instructions
Prepare the Cauliflower: Rinse the cauliflower. Then cut the cauliflower in half, through the middle of the stem. Cut off the stem from both halves. Use your hands to break many of the florets away. Use a paring knife to cut bite-sized florets. Cut branch stems into small, bite-size pieces. You should have around 7 to 8 cups of florets and small stem pieces. Learn more about how to cut cauliflower.
Heat the oil in a large pot over medium heat. Add the onion, celery, and carrots. Sauté until the vegetables are tender, about 10 to 15 minutes. Add garlic and cook for about a minute longer. Then add water, bouillon, wine, nutritional yeast flakes, cashews, and chopped cauliflower florets and pieces. Bring to a boil, then reduce to a simmer. Simmer for 20 minutes until cauliflower is tender. Remove from heat and let cool slightly. Use tongs to remove about 3 cups of the cauliflower florets from the pot.
Blend the soup: Remove the center cap from your blender lid. Fill the blender only halfway. Secure the lid on the blender and top with a kitchen towel. Blend on low speed for a few seconds, then slowly increase speed to create a creamy soup. Then add some of the reserved florets and give it a few quick bursts to break up larger pieces into bits. Transfer to a bowl. Repeat with remaining ingredients from the pan. Again, add some of the remaining florets and pulse. Be sure to leave some florets as a topping.
Season with salt and pepper to taste. Serve with cauliflower florets, croutons, toasted nuts, and/or sriracha.
