This Creamy Cauliflower Vegetarian Potato Soup is flavorful, delicious, and all kinds of healthy. Loaded with roasted cauliflower and potatoes, this easy soup recipe is vegan, vegetarian, dairy-free and Whole30 friendly.
Is it soup season?
It is the first week in January and am pretty sure it is officially soup season.
Wait. There is no such thing as “official soup season”? Seriously? We have National Donut and Spaghetti Day….but not soup season? Well, that’s not cool.
Creamy vegetarian potato soup
Well, who needs an official season to love on some amazing and healthy soup. This Cauliflower Vegetarian Potato Soup is so my cozy jam at the moment and a recipe you should totally add to your rotations.
It is loaded with flavors from roasted cauliflower (which is silly easy to make), sautéed onions, and hearty potatoes. It won over my cauliflower-iffy family (including my brutally honest 9-year-old) and is made with minimal, simple ingredients so that it can be something you enjoy without having to run to the store for one obscure ingredient.
The talented veggie-loading guru Heather Staller aided in the development of this recipe. Some of her other veggie-loaded TNN creations include Healthy Taco Stuffed Peppers, Healthy Sweet Potato Pancakes, and Banana-Spinach Pancake Pizza.
Why this creamy potato soup is so good:
- It is dairy-free. Lots of creamy soups get their richness from cream, milk or cheese. But this healthy soup achieves that flavorful creaminess from roasted cauliflower and potatoes blended together with olive oil, sautéed onions and garlic….making it the ideal plant based soup that still holds oodles of flavor.
- This soup is a delicious and easy way to get cauliflower into your belly. Something magical happens in the flavor department when you combine cauliflower and potatoes. Even the most iffy of cauliflower eaters will fall in love with this potato soup.
- It is adaptable. Use whatever kind of potato you have on hand. Grab frozen cauliflower florets out of the freezer to roast. Make it in your Instant Pot. Top it with whatever dazzles you. Make this soup work for you and your family.
- It’s easy to make and comes together quickly. My goal with every TNN recipe! This cauliflower potato soup is perfect thing to whip together when you need a hearty side or start to dinner.
FAQ
Can I use a different kind of potato? I find that Yukon Gold or other “yellow” potatoes have the best flavor in this soup, but any kind of potato you have will work well.
What kind of broth should I use for this soup? You can use homemade or store-bought vegetable or chicken broth (if vegetarian is not needed). If buying your broth, I recommend choosing a low-sodium variety so you can control the salt level of your soup by adding salt after it cooks. Since the color of broths vary greatly from brand to brand, the color of your soup might be lighter or darker in color than the pictures in this post.
Can I make this in the Instant Pot (pressure cooker)? Yes, you can make the soup all the way through Step 4 with the Saute function then do Manual high pressure for 3 minutes. Quick release then complete step 5, blending the soup.
Can I make this soup in the Slow Cooker/Crock Pot? Unfortunately, since you are roasting the cauliflower and sautéing onion in this recipe, it doesn’t work very well as a slow cooked soup.
Soup topping ideas
This vegetarian potato soup is pure magic on its own, but if you want to bump it up a notch, here are some topping ideas to bring this healthy soup next level.
- Croutons. Either you favorite store brand or easy homemade ones. I love the crunch these add to the soup and included a quick homemade version you can make. Omit for Paleo and Whole30 or make with gluten free bread if you need gluten free.
- Toasted sliced almonds or other nuts. These will also add a lovely crunch to this soup.
- Sliced green onion or chives will add some freshness
- Fresh parsley or dill
- Drizzle extra olive oil on top
- If don’t need the soup to be dairy-free, a sprinkle of parmesan or other shredded cheese on top would be delicious.
- Serve some bread on the side for dipping.

Creamy Cauliflower Vegetarian Potato Soup
Equipment
- Immersion Blender
Ingredients
- 3-4 cloves garlic cloves, skins on
- 1 head cauliflower, cut into small florets about 4 cups
- 3 tablespoons olive oil divided
- 2 cups chopped onion 1/2 large or 1 small
- 1 teaspoon dried Italian seasoning
- 1 pound Yukon Gold potatoes washed and cut into 1/2 inch pieces
- 2 tablespoons balsamic vinegar
- 4 cups vegetable broth
- 1 teaspoon Salt divided, or to taste
- black pepper to taste
Instructions
- Preheat oven to 425 ℉
- Place cauliflower florets and whole garlic cloves in the center of a baking sheet. Drizzle with one tablespoon of oil and sprinkle with a 1/4 teaspoon of salt. Toss together then spread out evenly across the pan. Roast until cauliflower is golden brown, about 12 to 15 minutes.
- While cauliflower is roasting, heat remaining 2 tablespoons of oil in a large pot over medium heat. Add chopped onion and saute until lightly browned. Stir in Italian seasoning and balsamic vinegar. Add potatoes then cover with broth. Simmer until cauliflower is finished roasting.
- Once cauliflower is done, set garlic cloves off to the side until cool enough to handle. Add cauliflower to the soup pot and simmer for 5 minutes or until all the vegetables are very soft. Peel skin off of the garlic and add it to the pot
- Once all the vegetables in the pot are well cooked, use a hand-held immersion blender to puree soup until smooth. Season with remaining salt and pepper. Taste and add more seasoning if needed.
- Enjoy warm. Top soup with a drizzle of olive oil, croutons, or other garnishes if desired.

I am so glad you enjoy it! Its a favorite of mine too!
Hi, I am really enjoying your recipes! Wondering if frozen cauliflower could be substituted in here?
Thank!
Hi Anne! I am so glad. Yes, you could replace the fresh cauliflower with frozen and roast it up. It might not have the exact same roasty flavor, but will still be delicious.
I could easily eat this potato soup every day!
