🥔Ingredients You'll Need
Notes on some of the ingredients, the full list of ingredients and their measurements can be found in the recipe card below.
Potatoes - use all-rounder potatoes, which have been peeled and uniformly chopped.
Leek tastes similar to an onion, you will only be using the white and light green parts of the leek.
Very rarely have I ever cut open a leek that didn’t contain dirt in between the layers. Be sure to thoroughly clean each layer prior to slicing.
You can do this by cutting off the tops (the dark green parts of the leeks are tough) and then slicing each leek lengthways to reveal the insides. Place the leeks into cold water with a capful of vinegar and then swirl around until the dirt is removed.
Rinse in cold water again to rid the vinegar and then pat dry.
Garlic - use freshly crushed garlic where possible, otherwise frozen or garlic flakes can be used.
Rolled oats add a creamy and rich element, be sure to purchase a gluten-free version*, as most oats are processed in facilities where gluten is handled.
Oats are a good source of plant protein.
Vegetable stock adds flavoring and brings all the ingredients together. No additional salt is needed.
Whichever vegetable stock you choose, read the label to ensure it is free of any ingredients you don’t want.
Black cracked pepper is used to add some pepperiness.
Fresh chives are added as a garnish.
🔪 Step By Step Guide
Step 1 - In a large pot heat over medium heat, 2-3 tablespoons of vegetable stock and add sliced leek. Fry until wilted.
Step 2 - Stir in garlic for about 30 seconds and add all other ingredients. Bring to a boil and then turn down the heat to low-medium and allow to simmer for 20 minutes.
Step 3 - Turn heat off and then use an immersion blender to blend until just smooth. Garnish with chives and serve warm.
⭐Pro Tips
Blending is only done until the texture is smooth, do not over blend as this can cause gumminess. Note; using an immersion blender will result in the soup being slightly textured.
Storage - once completely cooled down and store in the fridge in an airtight container for up to 5 days.
The consistency of this will coat the back of a spoon.
🥔Variations
A small amount of olive oil can be used if preferred to fry off the leek until lightly golden.
Vegetable stock generally carries enough salt, however, you may want to add salt to taste.
Chilli can be added for added heat, use either freshly minced chili, chili flakes, or chili oil - all to taste.
Fresh herbs such as thyme or marjoram can be added if desired. However, note this will alter the flavor profile.
Garnish can be left simple with just chives, or you can add homemade croutons or roasted chickpeas as croutons or various chopped fresh herbs and seeds.
🥣Serving Suggestions
Enjoy it with a side of salad, such as this simple cabbage salad called Kupus Salata. We also love enjoying it with my rocca salad, I love the onions and sourness of the dressing with it.
Or with some freshly made bread rolls.
❓FAQ
Absolutely. Once fully cooked, all the vegetables are soft enough to eat, just omit the step for blending this soup.
Yes, follow the instructions as per this vegan potato leek soup recipe, allow it to completely cool down to room temperature and then store in an air tight container in the fridge. You may need to stir through a small amount of water as the soup will thicken when chilled.

This potato and leek soup looks so warm and comforting. It's supposed to be cold and rainy here this weekend so will be making this soup. Can't wait. Thank you.

I love that this used oats as a natural thickener, it made the soup rich, creamy and and silky

I love how creamy and rich this soup is. I would never have thought to use oats in potato and leek soup. This is the perfect warming meal after a cold day.

So easy and so delicious. I never thought to use oats in soup before either.

it's been years since I made a potato leek soup. I do like your version that is totally pureed. It is interesting on adding oats to this soup but this does make it more hearty.
Leena
I’ve never made potato and leek soup with oats before, it really is creamy. Will be making it again. Thanks.
