Ingredients
- 1 tablespoon vegetable oil
- 2 leeks, white and light green parts thinly sliced
- 3 cloves garlic, minced
- 1 head cauliflower, cut into florets
- 2 cups (500 ml) vegetable stock
- 2 sprigs thyme or 1 teaspoon dried thyme
- 1 teaspoon salt
- ¼ teaspoon ground black pepper
- Green onion, sliced, for garnish – optional
- Crispy turkey bacon, for garnish – optional
How To Make Cauliflower Leek Soup
Step 1: Sauté the Leeks and Garlic
In a large pot, heat the vegetable oil over medium heat. Add the sliced leeks to the pot and sauté them for about 5 minutes, or until they become soft and translucent. Next, add the minced garlic and continue to sauté for another minute, allowing the wonderful aroma to fill your kitchen.
Step 2: Add Cauliflower and Stock
Once the leeks and garlic are fragrant and tender, add the cauliflower florets to the pot. Stir them in and let them cook for about 3 minutes. This short cooking time helps to enhance the flavor of the cauliflower. After that, pour in the vegetable stock, and add the thyme, salt, and black pepper. Stir everything together, making sure the cauliflower is submerged in the liquid.
Step 3: Simmer
Bring the mixture to a boil, then reduce the heat to low. Cover the pot and allow it to simmer for about 15-20 minutes, or until the cauliflower is fork-tender. The goal here is to cook the vegetables just enough so they can easily blend into a creamy soup.
Step 4: Blend the Soup
Once the cauliflower is tender, carefully remove the pot from the heat. Using an immersion blender, purée the soup until it reaches a smooth and creamy consistency. If you don’t have an immersion blender, you can transfer the soup in batches to a stand blender; just be sure to let it cool slightly before blending to avoid any splatters.
Step 5: Taste and Adjust Seasonings
After blending, taste the soup and adjust the seasonings as desired. If it needs a little more salt or pepper, feel free to add it. If you like a thinner consistency, you can stir in a little more vegetable stock or water until you reach your preferred thickness.
Step 6: Serve and Garnish
Ladle the soup into bowls and add your desired garnishes. A sprinkle of sliced green onions adds a pop of color and freshness, while crispy turkey bacon makes for a savory crunch that complements the creamy soup beautifully. Enjoy your delicious creation warm, and savor the comforting flavors!
Expert Tips
- For extra creaminess, consider adding a splash of coconut milk or almond milk after blending the soup.
- Always rinse leeks thoroughly, as they can contain dirt and sand in their layers.
- If you want a little spice, add a pinch of red pepper flakes while sautéing the leeks.
- Serve this soup with a slice of crusty bread for a complete meal.
Variations and Customizations
- Add other vegetables such as carrots or potatoes for added texture and flavor.
- Incorporate fresh herbs like parsley or dill for a fresh twist.
- Sprinkle some nutritional yeast for a cheesy flavor without dairy.
- For a richer flavor, consider roasting the cauliflower before adding it to the soup.
How to Store Leftovers
Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. To reheat, simply warm the soup on the stove over medium heat until it’s heated through. If the soup thickens while sitting, you can add a splash of vegetable stock or water to loosen it up. For longer storage, consider freezing the soup in portions. It can last up to 3 months in the freezer. Just make sure to allow it to cool completely before transferring it to freezer-safe containers.
