Why Cauliflower and Pumpkin Soup works
One of the earliest Yellow Glass Dish recipes was easy pumpkin soup. In that recipe, I shared about my experience of buying pumpkins in China and the great effort one would have to take to obtain a pumpkin then cook it. While I thought about those China days, I took my love for pumpkin soup and made a little twist. I added cauliflower.
You may be skeptical but this pumpkin cauliflower soup recipe does not have a strong cauliflower flavor. It also does not have dairy. How in the world can this soup be satisfying? Well, for one, it uses chicken stock as the base (instead of water). I have a recipe for making super flavorful chicken stock if you’re looking to make your own. This pumpkin cauliflower soup recipe also uses fresh garlic in the final blending process. If you’re not a fan of garlic, you can use one or two cloves instead of four.

Tips for Making this Low Carb Pumpkin Soup Recipe
When making this recipe with pumpkin and cauliflower, using the Instant Pot is a really easy method. I used fresh pumpkin in this recipe but if you use canned pumpkin, one 14 or 15 oz can would be fine. Just know that the color of the soup will be darker if you use canned pumpkin in this recipe.
In this pumpkin cauliflower soup recipe, there is no dairy. The way this soup becomes creamy is by using a quality blender. I personally love using my Vitamix for this soup recipe.
Instead of cooking the garlic in the soup, you add it at the time of blending. It gets cooked in the cauliflower pumpkin soup in the blender since the stock, pumpkin, and cauliflower are blended once they’ve been cooked. The chopped garlic releases a very fresh flavor by adding it at this step of the soup preparation.
I love to top soups with Maldon flake salt. It gives a nice texture and tastes great! You can also add fresh or dried parsley as a garnish.
If you enjoy texture in your soup you can set aside 1 cup of cooked cauliflower and pumpkin then blend the rest. After blending you can stir in the rest of the vegetables.
Alternative Keto Pumpkin Soup Cooking method:
If you do not have an Instant Pot, you could boil the contents of the soup on the stove for about 20 minutes on a low boil. Then carefully pour the hot contents into a blender (make sure your blender is safe for hot foods) then add the chopped garlic.
The Best Soup Spoons
In most of my soup recipes, you see these little metal spoons. They’re from China. I bought them at a massive market when I lived in China and have used them for years. They’re my absolute favorite spoon and are especially great for soup since they hold a lot more than a regular spoon. I tried to find ones that were similar for you, these ones are a bit shorter but quite similar.
