Ingredient Notes (with Substitutions)

Visual of ingredients for a vegan potato and leek soup recipe. Each ingredient is labelled with text overlay.

olive oil – use good quality olive oil for a flavourful base, if you prefer the recipe to be oil-free, omit and saute the veggies in water or vegetable broth
leek – you’ll need 1 large leek, remove the dark green ends and chop off the root at the bottom
potato – we like Yukon Gold potatoes best here!
thyme – the recipe calls for fresh thyme but you can use 1 tsp ground thyme if that’s all you have
coconut milk – use full-fat coconut milk for an ultra-creamy, velvety result, if allergies are an issue, replace with unsweetened almond or cashew milk

FAQs

Can you freeze potato and leek soup?

Yes. To freeze potato leek soup, let it cool then store in an airtight freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating.

What can I serve with potato leek soup?

This soup pairs well with a light salad or a sandwich. It’s also perfect with a warm soft or crunchy piece of bread to soak up all the goodness!

Can I leave the soup chunky?

Sure! For a chunkier potato and leek soup, I would recommend scooping out about half of the soup, blending until creamy then adding back to the unblended portion.

Instant Pot Instructions

Add the olive oil, celery and leeks to the Instant Pot and use the saute function to cook for 5-6 minutes until softened and fragrant.
Add everything except for the coconut milk and set the Instant Pot to 6 minutes at High Pressure.
Once it beeps, turn the steam handle to the Venting Position to release the pressure. Once the float valve drops, carefully open the lid.
Remove the bay leaves and stir in the coconut milk.
Blend right in the Instant Pot using an immersion blender or carefully transfer to a blender. Blend until smooth and velvety and enjoy!
