Looking for a tasty and cozy soup to warm you up? This Cauliflower Leek Potato Soup is just perfect! This soup is great for a quick dinner or lunch with its creamy texture and rich flavors.
Cauliflower leek potato soup is especially popular during the colder months. It's perfect for fall and winter when you crave something warm and comforting. And what can be better than a bowl soup?
Ingredients
Potato-based soups are a classic comfort food, and adding cauliflower and leeks makes them even better and more nutritious! I do love this combination for its delightfully creamy texture ❤️
Cauliflower is the star of this soup, providing a mild, nutty flavor and a creamy texture when blended. It's rich in vitamins C and K, and a good source of fiber.
Leeks add a sweet, onion-like flavor to the soup. They are lower in calories and high in vitamin K, which is important for bone health. Use the white and light green parts, and make sure to clean them thoroughly to remove any dirt hidden in the layers.
Potatoes make the soup hearty and creamy. Yukon Gold or russet potatoes are best because they become very tender and blend smoothly.
Onions provide a base flavor that's essential in many soups.
Garlic adds a wonderful depth of flavor and a bit of a kick. It's known for its potential health benefits, including boosting the immune system and reducing inflammation.
Milk makes the soup creamy and smooth. You can use any type of milk, but whole milk will give the creamiest texture. A heavy cream is an option, if you don't mind extra calories 🙂
Olive oil here is used to sauté the vegetables. It adds a healthy fat and enhances the flavor.
Fresh thyme adds a lovely herbal note to the soup. It is packed with vitamins C and A, and has antioxidant properties. If you don’t have fresh thyme, dried thyme can be used, but reduce the amount by half.
A stock cube boosts the soup's flavor and is an easy way to add seasoning. Vegetable stock cubes are common, but you can also use chicken stock cubes if you prefer. Look for low-sodium versions to control the saltiness of your soup.
Other ingredients: salt. black pepper, red pepper flakes, or parmesan for garnish (optional).

Instructions
I promise, even if you never cooked anything (which I doubt), you will be a winner at the end of this culinary quest!
As a start, Peel and dice the potatoes. Break the cauliflower into florets. Clean the leeks thoroughly between the leaves(!) and chop the white and light green parts.
In a large pot or Dutch oven, heat the olive oil over medium heat. Add the chopped onion and minced garlic. Sauté until the onion is soft, for about 4 minutes.
Add the leek and cook for another 5 minutes.
Add the cauliflower florets, potatoes, thyme, water, stock cube, salt and pepper. Bring to a boil, then reduce the heat to medium-low and simmer until the vegetables are tender, for about 25 minutes.
Use an immersion blender to blend the soup until smooth. If you don't have an immersion blender, a regular blender works fine—just blend in small batches.
Stir in the milk and let it heat up for a few minutes - don't boil!
Hint: To save time, I like to prepare the leeks while garlic and onion are already sauteing, and, after I add the leeks I get to prep the potatoes and cauliflower. But you can prepare the vegetables before you start cooking, it is absolutely fine and there is no time pressure afterward!
Variations
Here are several variations you can try to customize your cauliflower leek potato soup to your liking:
- Add a cheesy twist by stirring in 1 to 2 cups of shredded cheddar cheese at the end of cooking. This will make the soup extra creamy and rich.
- If you enjoy a bit of heat, add a pinch of red pepper flakes or a chopped fresh chili to the soup while it’s cooking.
- For a vegan version, use vegetable broth and substitute the milk with coconut milk or almond milk. Coconut milk adds a nice, subtle sweetness and creaminess. Ensure any added toppings, like cheese or sour cream, are also plant-based.
- Turn your soup into a loaded baked potato version by topping it with crispy bacon crumbles, shredded cheddar cheese, sour cream, and chopped green onions.
- Add a teaspoon of curry powder and a can of coconut milk for a Thai twist.
You can also add other vegetables or herbs - literally, the sky is the limit!
