How to Make 3-Ingredient Cauliflower Soup
- Simmer the cauliflower: Place a cup of water in a saucepan and simmer until tender – about 25 minutes.
- Blend the tender, cooked cauliflower with an immersion blender until smooth, achieving a consistency similar to that of mashed potatoes.
- Whisk in water or broth until creamy and a consistency you like.

Tips
- To achieve the perfect consistency, gradually add the liquid to the soup.
- Season with salt and pepper to taste just before serving.
- Experiment with texture; if you prefer a chunky soup over a silky smooth soup, remove some of the florets before blending and add them back in after the soup has been blended.
- Save time and buy pre-cut cauliflower from your grocery store.
How to Store Leftovers
Let the cauliflower soup cool to room temperature before storing it. Transfer it to an airtight container and refrigerate for up to 4 days. For longer storage, freeze the soup in portion sized container for up to 3 months. When reheating, add a splash of water or broth if needed to loosen the texture.
