Learn how to make creamy roasted cauliflower soup without cream using one of my favorite, easy low carb soup recipes. It’s great for anyone trying to cut carbs and calories while still enjoying what they eat. This recipe starts with my air fryer roasted cauliflower which takes less than 15 minutes to prepare and uses my lemon butter garlic sauce for fresh bright flavor.
Why Make This
- Keto and Low-carb: My recipe uses cauliflower and other low-carb ingredients, making it a great option for low-carb and keto dieters. Plus, to keep it keto-friendly, this recipe skips carb-loaded thickeners like cornstarch and flour.
- Vegetarian Option: This roasted cauliflower soup recipe uses chicken broth for added flavor and proteins. But, if you’re vegetarian, you can use vegetable broth instead.
- Creamy Without Cream: Use my lemon butter garlic sauce to add fresh and bright flavor to this creamy cauliflower soup without cream.
Ingredients Needed
- Cauliflower: I buy these pre-cut and packed to save time, but you can cut a whole cauliflower into florets to make this soup too.
- Olive oil
- 24 Herbs sprinkle seasoning: This is a salt-free herb seasoning blend that adds flavors like garlic, tarragon, and rosemary in one bottle.
- Natural ancient sea salt
- Black pepper
- Lemon butter sauce: this easy recipe takes less than 10 minutes to make and can be used in this soup, but also in my lemon garlic butter baked shrimp and lemon garlic butter baked salmon.
- Chicken broth: this adds flavor, but you can also use chicken bone broth to add protein
- Mascarpone or Softened Cream Cheese: You can add creaminess without cream
How To Make Creamy Cauliflower Soup Without Cream
- Drizzle the cauliflower with olive oil, herb seasoning, sea salt, and black pepper.
- Roast the seasoned cauliflower florets in the air fryer at 400 degrees for 12-15 minutes. You can toss them midway through and check for browning and softening at the 12-minute mark.
- Make the lemon garlic butter sauce.
- Make the soup by adding the roasted cauliflower, broth, mascarpone, and lemon garlic butter sauce to a blender. Use the blender’s soup setting to incorporate.
Tips & FAQs
- Buy prepared cauliflower: Buying pre-cut and packaged cauliflower florets will save prep time and energy.
- Use vegetable broth for vegetarian soup: If you’re a vegetarian or are making cauliflower soup for a vegetarian, you can switch up the chicken broth with vegetable broth.
- Add mascarpone or softened cream cheese: Use either of these to achieve a creamy texture and taste without cream.
- Use the air fryer to save time: If you have an air fryer, use it here. Air frying cauliflower florets takes about 15 minutes, and that’s half the time you’ll use with the traditional oven.
- Save some cauliflower florets for garnishing: When mixing the cauliflower with the rest of the ingredients to make the soup, spare a few florets to garnish the soup as you serve.

My roasted cauliflower soup isn’t runny. But, if you want more thickness and don’t mind the carbs, use cornstarch or flour. For keto or low-carb options, xanthan gum is a perfect thickener. I use it to thicken my keto tomato soup.
Cauliflower soup can stay in the fridge for 3-5 days before going bad.
If your soup tastes uninspired, you haven’t seasoned it enough. Use my DIY lemon garlic butter sauce and herbs sprinkle seasoning for bold flavors.
