❤️ Why You’ll Love This Recipe: This is the ultimate creamy cauliflower soup. It’s silky smooth, thick, cheesy, and totally satisfying. Plus, it takes one pot and 10 ingredients!
We didn’t eat much cauliflower growing up—I’d only ever had to cooked boiled, and…um…I don’t recommend it that way.
However, as an adult, I’ve learned that I really enjoy it when it’s prepared with lots of seasoning. This creamy, easy soup really fits the bill there.
This is one of our new favorite Instant Pot soup recipes! We love to serve the soup with a side of 3-Ingredient Instant Pot Cornbread.
Ingredients for Cauliflower Soup
You don’t need any special or hard-to-find ingredients to make this creamy soup. Here’s what you need:
- Cauliflower. Cut the cauliflower into small bite-sized pieces so they cook evenly and thoroughly.
- Garlic. Fresh garlic will give your soup a better flavor, but you can use ½ teaspoon garlic powder in a pinch.
- Onion. To make a flavorbase for your soup.
- Fresh thyme leaves. You could replace this with 1 teaspoon dried thyme.
- Low-sodium chicken broth. For vegetarian, use vegetable broth.
- Whole milk. This will provide the thickest, creamiest texture.
- Pinch nutmeg for a hint of added warming flavor.
- Parmesan cheese. Use shredded cheese so it melts nicely.
- Lemon juice. A bit of acid to finish your soup helps round out the flavors.
How to Make Creamy Cauliflower Soup in an Instant Pot
We love that this dump-and-go soup is so fast and easy. Simply add the veggies, broth, and seasoning to the pressure cooking pot. Pressure cook for 8 minutes.
After the pressure releases, add as much milk as you like to reach your desired consistency. Then use an immersion or regular blender to puree the soup smooth.
Finally, melt in the cheese and add a squeeze of lemon juice to finish the dish. That’s it!
Important Tips for Making Cauliflower Soup
There’s no need for sautéing at the beginning of this recipe. The beauty is that you can simply dump everything into the pressure cooker pot, lock the lid in place, and let it cook!
You can use an immersion blender to make the soup smooth. If you don’t have one, use a regular upright blender. If you like a slightly chunky soup, you can leave some larger pieces of cauliflower in there.
Be sure not to add the cheese all at once. Add shredded cheese ¼ cup at a time, stirring until it’s fully melted before adding more. Otherwise, the temperature of the soup will drop too quickly and the cheese will clump up, not melt.
