When the weather gets chilly, I start craving a no-fuss creamy soup. While my easy butternut squash soup is my go-to, this soup is my second favorite.
Although this bowl of French leek soup is dairy-free and vegan, you can always make it your own, depending on your dietary restrictions.
💖Reasons to Love this Recipe
- It's great for the whole family.
- Diary-free, gluten-free, and vegan.
- This leek and Parsnip soup is quick, tasty, and a healthy version of leek soup.
- It is super easy to make, vegan, creamy, and hearty.
- It is nutritious and only requires a few steps.
📃Ingredient Description
Here are the ingredients you'll need to make this soup.

- Olive oil: Any neutral-tasting oil works fine.
- Sweet onion: I prefer sweet or white onion for this dish. If you only have the purple onion, that's fine too. Cook it until it's translucent.
- Shallots: This is used for added flavor; if you don't have it, you can skip it, as the difference isn't primarily noticeable.
- Leeks and Parsnip: It's a leek and parsnip soup, so by all means, use leeks and parsnip.
- Vegetable stock: vegetable broth or stock works for this recipe. You can equally use water; if you do, adjust the seasoning to taste.
- Milk: Use good-quality canned coconut milk, like the Thai Kitchen brand, and oat milk. My tiger nut milk will work just fine. If you don't have diet restrictions, use heavy cream.
- Cheese: This is a vegan soup, hence the vegan cheese. Feel free to use real cheese like Monterey Jack or sharp cheddar.
- Garlic and ginger: If you don't have fresh garlic cloves or ginger, use garlic ginger paste instead.
- Spices & seasonings: I used a combination of fresh thyme, ground Coriander, garam Masala, black pepper, and salt.
Please refer to the recipe card for the exact measurements.

Looking to change this leek and parsnip soup recipe by substituting a few things? We have a few fantastic ideas that will help you achieve perfect flavors. These are:

How to Make Vegetarian Leek Soup
Detailed instructions are outlined in the recipe card below, but here are a few steps with visuals to guide you:


Step 1: Cook the onion and shallots. Once slightly softened, add the leek, parsnip, garlic, ginger, and thyme. Sauté for a couple of minutes.
Step 2: Next, add the spices and cook. Deglaze the pan with the stock, add the seasoning and salt, and allow it to boil. Remove from heat.
Step 3: Purée the leek and parsnip mix until it's smooth.
If you have a blender or food processor that can handle hot liquids, use it to puree. If not, set aside to cool.
Step 4: Once blended, return the mixture to the stove and cook on low heat. Add the cheese and stir until it melts. Serve hot.

Storage
To store, allow the soup to cool down completely, pour it into an airtight container and refrigerate for up to 3 days. I don't recommend freezing as the oat milk can separate, giving it a weird texture.
What Goes Well With Leek Soup?
There are so many sides you can serve with leek soup. However, the one essential side is bread. You can serve it with zopf, French bread, garlic bread, or dinner rolls. It is just the perfect side to scoop the soup.
✅Recipe FAQS
All parts of the leek are edible. The white and light green sections are commonly used in soups, while the dark green part, which requires longer cooking, is mainly used for stocks and broths. The white and light green parts are more versatile and suitable for soups and stews.
Leeks are as versatile as onions and complement many ingredients. In soups, they pair well with tomatoes, potatoes, carrots, parsnips, and mushrooms.
Their sweet flavor goes nicely with herbs like tarragon, chives, oregano, and thyme, as well as with chicken, pork, cream, and cheese.

Absolutely! The green part of leeks is just as edible as the white parts. The leeks' light and dark green parts are crunchy and loaded with flavors.
