This cauliflower soup recipe will absolutely satisfy your craving for warm, creamy soup—no cheese required.

I know “cauliflower soup” might not sound super appealing if you’ve never had it before. Trust me, it can be so delicious! Today, I’m sharing my favorite cauliflower soup recipe, and I can’t wait for you to make it at home.

My friend Tessa introduced me to cauliflower soup a few years ago. I loved it so much that I developed my own recipe for my cookbook, Love Real Food.

As the temps and leaves have dropped this fall, I’ve had a hankering for warm, creamy soups. So, I thought I’d share a slightly simplified version of my cauliflower soup for everyone to enjoy. Let’s make some.

Why You’ll Love This Cauliflower Soup

This soup calls for basic ingredients but yields amazing flavor. If you have a head of cauliflower in the fridge, you probably have everything else you’ll need.

This cauliflower soup is the perfect accompaniment to salads and sandwiches. This traditional cauliflower soup will go with just about any other fall or winter flavors, including butternut squash, Brussels sprouts, and greens like arugula and kale. It’ll warm you up without weighing you down!

This soup freezes well for later. This recipe doesn’t yield a ton (about 4 medium bowls), but if you have extra, just freeze it!

This creamy soup is special diet-friendly. It’s gluten free as written. Check my recipe notes to learn how to make this soup vegan/dairy free by using cashews instead of butter.

How to Make the Best Cauliflower Soup

Healthy soup with cauliflower, carrot and potatoes.

1) Roast Your Cauliflower

Behind that creamy beige exterior, you’ll find loads of irresistible roasted cauliflower flavor. Roasted cauliflower is key here—cauliflower develops caramelized notes with a greater depth of flavor as it roasts in the oven.

2) Build Flavor

Once your roasted cauliflower is almost done, you’ll sauté onions in a soup pot until tender, then add garlic and vegetable broth. Then, add your roasted cauliflower and simmer the mixture on the stove for about 20 minutes to meld the flavors.

3) Add Butter for Creaminess

You’ll transfer the contents of the pot to a blender and add butter. Butter is an easy way to add mega creamy, luxurious flavor and texture without any cream (I borrowed this technique from my butternut squash soup). If you’re like me, you always have butter in the fridge, but rarely heavy cream.

4) Blend Until Completely Smooth

I recommend blending this soup in a stand blender, rather than an immersion blender, because stand blenders yield the creamiest results. Fortunately, the ingredients used here are fairly soft, so even an inexpensive stand blender should work well (I used my fancy Vitamix, affiliate link). The final texture, in my opinion, is absolutely worth dirtying the blender bowl for.

5) Season with Nutmeg and Lemon Juice

We’re using small, subtle amounts of nutmeg and lemon juice here. You probably won’t be able to pinpoint them while you’re sipping your soup, but they offer a certain je ne sais quoi factor. They take this soup from great to fantastic!
