How to Make Creamy Vegan Leek Soup with Crispy Sage

Leeks are notoriously annoying to clean. So I like to take off any limp outer leaves first, chop them roughly, and then wash thoroughly in water.

When you have your ingredients prepared, the leeks are simply cooked soft with some salt and garlic. The salt draws moisture out of the leeks so you don’t need to add any oil.

When they are soft, add a vegan chicken-style bouillon cube and a couple cups of water.

Separately, blend two tablespoons of raw cashews with a cup of hot water to create cashew cream. Add the cream to the pot.

Then you’ll want to blend half the soup to make it smooth and creamy. You can use an immersion blender in the pot but I prefer to scoop it out to my Vitamix. The texture is so much better that way.

Keep the soup simmering on the lowest heat while you make your crispy sage.

How to Make Crispy Sage

First wash your fresh sage leaves and pat them dry. Then you can heat a pan with a bit of oil over medium-high. When the pan is hot, lay down the sage leaves and let them sizzle for about 20 seconds. Be careful not to let them burn.

The crispy sage becomes smoky, savory, and is just wonderful when crumbled over this soup. It’s also great on pasta and on sandwiches too.

  • 1 cube vegan chicken-style bouillon (1 tsp powder)

  7. Seperately heat a nonstick pan with a thin layer of oil over medium to medium high heat. When the pan is hot, lay down the washed and dried sage leaves. Let pan-fry for about 20 seconds; until the sage leaves are crispy but not burned. Remove immediately.
