Is this a vegan leek and celery soup?

If you use non-dairy milk rather than heavy cream, this soup is suitable for a vegan diet.

Do I need to peel the potatoes?

No need to peel the potatoes! The skin has lots of flavor. But of course, if you prefer to peel them, that works too.

How do you prepare leeks?

Give them a good wash, including between the leaves. Remove any tough outer leaves. Slice off the root, as well as the dark green leaves. Slice the leeks lengthways, then across the white and light green leaves.

List of ingredients

1 tbsp olive oil – used for sautéing the aromatics.
1 large leek – washed and diced.
3 celery sticks – diced.
2 medium russet potatoes – diced.
1/4 onion – diced.
2 garlic cloves – minced or finely diced.
2.5 cups vegetable stock – provides the liquid base.

1 tsp dried parsley – provides a mild herbal note.
2 bay leaves – simmered for depth of flavor.
1/4 cup non-dairy milk – creates a creamy finish.
pinch salt – for seasoning.
pinch black pepper – for a hint of spice.

step-by-step instructions

Sauté Aromatics: Drizzle the olive oil into your pot and then add the onion, garlic and herbs. Fry on a low heat for 4-5 minutes or until the onion has softened.
Cook Vegetables: Add the leeks and celery to the pot and cook for a few minutes, then tip in the diced potatoes. Season with salt and black pepper. Cook for 5-7 minutes. If the potato starts to stick, add a splash of water.
Simmer Soup: Pour in the vegetable stock and bring to a boil. Reduce the heat, give it a good stir and cook on a low to medium heat for 18-20 minutes until the potato is fork tender. Pour in the non-dairy milk and stir again.
Blend: Remove the bay leaves. Use an immersion blender to blend the soup, or add batches to a food processor to blend.
Serve: Ladle into your bowls and top with fresh herbs if you wish. Serve immediately and enjoy!

Optimizing Your Preparation Process

Cleaning Leeks Thoroughly

Leeks often trap sand and soil between their concentric layers. To clean them, slice the leek lengthways from the root to the stem. Run the sliced halves under a stream of cold water, gently separating the layers to wash away all debris.

Selecting the Best Potatoes

Russet potatoes are ideal for this soup because their high starch content breaks down during blending to naturally thicken the liquid. If you prefer a slightly creamier, more buttery flavor, Yukon Gold potatoes are an excellent alternative. Avoid using waxy red potatoes as they do not break down as easily.

Dicing for Even Cooking

Ensure all diced vegetables are roughly the same size to guarantee they cook at the same rate. Cut the potatoes into small half-inch cubes so they soften within the 20-minute simmering window. Uniformly diced leeks and celery will also sauté more evenly without burning.

Customizing the Flavor Profile

Adjusting the Herb Balance

If you prefer a more intense herbal flavor, you can increase the dried thyme and parsley by an additional half teaspoon. For a fresher taste, stir in a tablespoon of chopped fresh parsley at the very end of the blending process. Avoid boiling fresh herbs for long periods as they lose their brightness.

Replacing the Non-Dairy Milk

You can use cashew cream or full-fat coconut milk for a richer, denser consistency. If you prefer a lighter version, unsweetened almond milk or soy milk works well. Ensure the milk is unsweetened to avoid adding an unwanted sugary taste to the savory soup.

Using Alternative Stocks

While vegetable stock is standard, you can use a low-sodium mushroom broth to add an extra layer of umami. If you have homemade vegetable scrap stock, it will provide a deeper flavor. Always taste your stock first, as some store-bought versions are very salty.

Texture and Consistency Guide

Achieving a Thicker Soup

To increase the thickness without adding more milk, add an extra half of a diced potato during the second step. The additional starch will create a heavier body once blended. Alternatively, you can simmer the soup uncovered for an extra 5-10 minutes to reduce the liquid.

Thinning the Soup for a Lighter Feel

If the soup is too thick after blending, stir in a small amount of additional vegetable stock. Add the liquid one tablespoon at a time and stir until you reach your desired consistency. This prevents the soup from becoming watery.

Blending Techniques for Maximum Smoothness

An immersion blender is the most efficient tool for this recipe as it blends directly in the pot. For an ultra-smooth, velvet-like texture, use a high-speed countertop blender in small batches. Be careful not to over-blend, as over-processing starches in potatoes can occasionally make the texture gluey.

Serving and Pairing Recommendations

Best Bread Pairings

Serve this soup with a toasted sourdough baguette for a tangy contrast to the mild leeks. Crusty ciabatta or warm rye bread also provide a sturdy texture for dipping. For a gluten-free option, toasted seed crackers or oat cakes are suitable.

Complementary Side Salads

A crisp green salad with a light lemon vinaigrette balances the creaminess of the soup. Consider a salad with mixed baby greens, sliced cucumbers, and a dash of apple cider vinegar. A grain-based salad with quinoa and roasted vegetables also makes the meal more filling.

Garnish Ideas for Visual Appeal

Top each bowl with a sprinkle of fresh chives or a swirl of olive oil for a professional look. A pinch of cracked black pepper or a few red pepper flakes can add a slight kick. A small dollop of non-dairy Greek yogurt can add a tangy contrast.

Storage and Preservation Methods

Refrigeration Guidelines

Allow the soup to cool completely before transferring it to an airtight glass or plastic container. Store it in the main body of the refrigerator, not the door, to maintain a consistent temperature. The soup will stay fresh and safe to eat for 3 to 4 days.

Freezing for Long-Term Use

This soup freezes well if you omit the non-dairy milk until the reheating stage. Pour the blended soup into freezer-safe bags or containers, leaving about an inch of headspace for expansion. It can be stored in the freezer for up to 3 months.

Proper Reheating Techniques

Reheat the soup slowly on the stovetop over medium-low heat to avoid scorching the bottom. If the soup has thickened significantly in the fridge, stir in a splash of water or stock. Stir frequently to ensure the heat is distributed evenly throughout the pot.

Troubleshooting Common Cooking Issues

Preventing Vegetables from Sticking

If the potatoes begin to stick to the bottom of the pot during the initial sauté, immediately add a tablespoon of water or vegetable stock. This deglazes the pan and loosens the browned bits. Keep the heat at a medium-low setting to prevent the sugars in the onion and leek from burning.

Managing the Thickness of the Blend

If the soup appears too thick immediately after blending, remember that it may thicken further as it cools. Always blend until just smooth. If you used a food processor, ensure you scrape down the sides to avoid clumps of unblended potato.

Avoiding Bitter Flavors from Burnt Garlic

Garlic burns much faster than onions and leeks, which can introduce a bitter taste to the entire batch. Add the minced garlic during the last 60 seconds of the initial sauté process. If the garlic turns dark brown, it is best to start the sauté over to ensure a clean flavor.

Frequently Asked Questions

Is this recipe vegan?

Yes, this recipe is vegan as long as you use a plant-based non-dairy milk and vegetable stock. Ensure your vegetable stock does not contain any animal-derived additives.

Do the potatoes need to be peeled?

Peeling the potatoes is optional. Leaving the skins on adds extra nutrients and a more rustic flavor to the soup. If you prefer a perfectly smooth, pale color, peel them before dicing.

How do I handle the leek greens?

Use only the white and light green parts of the leek for this soup. The dark green tops are too tough and fibrous for a blended soup. Save the dark greens in the freezer to use for making future vegetable stocks.

Can I use a different type of oil?

Yes, you can substitute olive oil with avocado oil or any other neutral cooking oil. Avoid using butter if you want to keep the recipe vegan. The oil primarily serves to soften the vegetables and carry the flavor of the herbs.

What if I don’t have an immersion blender?

You can use a standard blender or a food processor. Transfer the soup in small batches, filling the container only halfway to prevent the hot liquid from splashing out of the lid. Use a towel to hold the lid firmly in place while blending.
