You read that right: three ingredients and 15 minutes. If that sounds too simple, try the soup and you’ll see why it’s a keeper. Three adjectives sum it up best:

  • Velvety
  • Silky
  • Creamy (without dairy)

Despite its creamy mouthfeel, this soup contains no milk, cream or butter. It relies on the cauliflower itself, warm stock and a touch of olive oil to create a rich, satisfying texture. From there it’s a perfect canvas for toppings — herbs, crunchy chickpeas, shredded cheese, crispy bacon or a swirl of pesto all work beautifully.

Why You’ll Love This Recipe

  • Fast. The entire recipe takes about 15 minutes from start to finish.
  • Minimal ingredients. Cauliflower, warm vegetable or chicken stock and olive oil are all you truly need.
  • Customizable. Top it with whatever you like to add texture and flavor: fresh herbs, crunchy beans, grated cheese or crisp bacon.

Ingredients

  • Cauliflower: Two medium heads, trimmed and cut into florets. Pre-cut florets save time.
  • Vegetable or chicken stock: Use warm stock when blending to preserve heat and deepen flavor.
  • Olive oil: Adds silkiness and healthy fat; a good extra-virgin olive oil shines here.

Optional: toppings such as fresh herbs (chives, parsley), roasted or crispy chickpeas, grated cheese, bacon bits or a drizzle of pesto or chili oil.

How to Make Simple Cauliflower Soup

  1. Cook the cauliflower: Bring a large pot of water to a boil. Add the florets and boil until just tender, about 5 minutes. Drain well.
  2. Blend the soup: Combine the cooked cauliflower, warm stock and olive oil in a blender. Blend until completely smooth, stopping to scrape down the sides as needed.
  3. Season and serve: Taste and season with salt and freshly ground black pepper. Serve warm with your favorite toppings.

Pro tip: Make sure the stock is warm before blending so the finished soup stays hot and you won’t need to reheat it.

Kelly’s Recipe Tips

  • Cutting florets: Remove outer leaves and cut the cauliflower in half. Use a paring or chef’s knife to cut V-shaped wedges around the core, then separate florets by hand or with a knife.
  • Blender choice: A high-speed blender creates the smoothest texture. If using a regular blender, blend in batches and be patient when achieving a silky consistency.
  • Use good olive oil: Because the recipe is simple, a flavorful extra-virgin olive oil will enhance the overall taste.

Storage and Freezer Tips

Refrigerate: Store in an airtight container in the refrigerator for up to 4 days.

Freeze: Freeze in airtight containers for up to 6 months. Thaw in the refrigerator overnight and reheat gently on the stove.

Frequently Asked Questions

How do you thicken cauliflower soup?

To thicken the soup, add more cooked cauliflower and blend until smooth. Start with less liquid when blending; you can always thin it later.

What makes a bowl of soup more flavorful?

Salt enhances flavor; a splash of acid such as lemon juice or a little vinegar brightens the soup. Fresh herbs and crunchy toppings add contrast and depth.

How long does cauliflower last in the fridge?

Fresh cauliflower typically keeps about 4–5 days in the refrigerator. Discard any parts with mold or soft spots before cooking.

Kelly’s Notes

  • To cut cauliflower into florets, remove outer leaves, halve the head and cut out the core in a V-shaped wedge, then separate florets.
  • A high-speed blender yields the silkiest texture, but a standard blender works if you blend thoroughly and in batches.
  • Choose a good-quality extra-virgin olive oil — its flavor matters in this simple soup.
