A British classic beloved food, the Leek & Potato Soup doesn't really need introductions. Here's my vegan take made it easier and quicker using the Instant Pot.
To make the soup in a traditional pot:
1) Sauté finely chopped leeks, onions and cubed potatoes in the melted butter and oil.
2) Add the seasonings and vegetable broth + roughly 200 ml extra (as it will evaporate during cooking time) and simmer for 25-30 minutes or until the potatoes are as soft as they break apart.
3) Add the plant milk (+25-50ml extra if you like it runnier) and blend till smooth.
4) Adjust the seasoning if needed and serve.
