Ingredients You’ll Need
- 1 tablespoon olive oil
- 1 tablespoon vegan butter (optional for added richness)
- 2 large leeks, cleaned and sliced (white and light green parts only)
- 2 cloves garlic, minced
- 4 medium potatoes, peeled and diced
- 4 cups vegetable broth
- 1 cup unsweetened plant-based milk (such as oat or almond)
- 1 teaspoon salt (adjust to taste)
- ½ teaspoon black pepper

Pro Tips
- Clean the leeks thoroughly before slicing, as they often hold dirt between the layers. Rinsing them well ensures a clean, smooth soup.
- Cut the potatoes into evenly sized pieces so they cook at the same rate. This helps create a consistent texture when blending.

- Blend the soup thoroughly for the smoothest texture, especially if you prefer a creamy finish. Taking an extra minute here makes a noticeable difference.
- Adjust the thickness by adding more broth or plant-based milk a little at a time. This helps you reach the consistency you like best.
- Add the lemon juice at the end to brighten the flavor without overpowering the soup. It helps balance the richness naturally.
Tools You’ll Need
- Large pot or Dutch oven
- Cutting board
- Sharp knife

Substitutions and Variations
Make It Extra Creamy
Add a splash of coconut milk or cashew cream instead of plant-based milk. This creates a richer texture while keeping the soup dairy-free.
Add More Vegetables
Stir in chopped celery or carrots along with the leeks. This adds more depth of flavor and a bit of natural sweetness.
Change the Herbs
Use fresh herbs like parsley or chives instead of dried thyme. This gives the soup a lighter, fresher finish.
Make It Heartier
Add cooked white beans before blending to increase protein and make the soup more filling. It blends smoothly into the base.
Keep It Lighter
Use more broth and reduce the amount of plant-based milk slightly. This creates a thinner soup that still feels comforting but less rich.
Make Ahead Tips
This creamy vegan potato leek soup is a reliable option for making ahead because it holds its texture and flavor very well. You can prepare the full batch a day or two in advance and store it in the refrigerator in a sealed container. The flavors continue to settle, giving the soup a slightly deeper and more balanced taste.
If you prefer to prep in stages, you can clean and slice the leeks, mince the garlic, and dice the potatoes ahead of time. Store the leeks and garlic in airtight containers, and keep the potatoes submerged in water in the refrigerator to prevent browning. This simple prep makes the cooking process much quicker when you are ready to start.
For longer storage, the soup can be frozen after it has been fully cooked and blended. Let it cool completely before transferring to freezer-safe containers, leaving a little space for expansion. Thaw it overnight in the refrigerator and reheat gently to maintain its smooth consistency.
Instructions
Step 1: Prepare the Vegetables
Start by thoroughly cleaning the leeks, then slice them into thin rounds using only the white and light green parts. Dice the peeled potatoes into evenly sized pieces and mince the garlic so everything cooks evenly.
Step 2: Sauté the Leeks
Heat the olive oil and vegan butter in a large pot over medium heat and add the sliced leeks. Cook slowly, stirring occasionally, until they soften and become fragrant without browning too much.
Step 3: Add the Garlic
Stir in the minced garlic and cook for about a minute until it becomes fragrant. Be careful not to let it brown, as this can change the flavor of the soup.
Step 4: Add Potatoes and Broth
Add the diced potatoes to the pot and pour in the vegetable broth, making sure everything is mostly submerged. Stir gently to combine the ingredients evenly.
Step 5: Simmer Until Tender
Bring the mixture to a gentle boil, then reduce the heat and let it simmer for about 15 to 20 minutes. The potatoes should become very soft and easy to pierce with a fork.
Step 6: Blend Until Smooth
Use an immersion blender to puree the soup directly in the pot until it becomes smooth and creamy. If using a countertop blender, work in batches and blend carefully.
Step 7: Add Creaminess and Season
Stir in the plant-based milk along with the salt, pepper, and optional thyme. Mix well and let the soup warm through, adjusting the thickness with extra broth if needed.
Step 8: Finish and Adjust
Add the lemon juice and taste the soup, adjusting seasoning as needed. Let it sit for a minute or two before serving so the flavors settle.
Serving Suggestions
Serve this soup warm with a slice of crusty bread or a soft roll on the side. The bread pairs well with the smooth texture and helps make the meal more filling.
You can also add a simple green salad with a light dressing to balance the richness of the soup. The fresh, crisp texture complements the creamy base nicely.
For a slightly heartier meal, serve the soup alongside a sandwich or wrap. This works well for lunch or dinner and helps round out the plate.
A light drizzle of olive oil or a sprinkle of fresh herbs on top can add a simple finishing touch. These small additions bring extra flavor without changing the dish too much.
If serving for family meals, you can offer toppings like seeds or croutons so everyone can customize their bowl. This makes the meal more flexible and enjoyable.
Leftovers and Storage
Store any leftover soup in an airtight container in the refrigerator for up to three to four days. The texture will remain smooth, and the flavor often improves slightly after resting. This makes it a practical option for meal prep or quick meals later.
When reheating, warm the soup gently on the stovetop over medium-low heat, stirring occasionally to prevent sticking. You can also use the microwave in short intervals, stirring between each to ensure even heating.
The soup may thicken after being stored, which is completely normal. Add a splash of vegetable broth or plant-based milk while reheating to bring it back to your preferred consistency.
To freeze, allow the soup to cool completely before placing it in freezer-safe containers. Leave a bit of room at the top for expansion, and thaw overnight in the refrigerator before reheating gently.
