Instructions
Warm the ghee or oil in a large soup pot over a medium heat. Once warmed, add the spring onion greens and leek greens. Cook for 2-3 minutes or until fragrant, bright green and slightly softened. Add the stock and potato pieces and stir to combine. Pop the lid on and cook for 10-15 minutes or until the potatoes are easily sliced through and knife tender.
Use a stick blender (see notes) to blend your soup until it is your desired consistency. I like my potato soup smooth, but you can leave chunks if you like. Add the cream (if you’re using it) and milk and stir to combine. If the soup is too thick for your tastes, add more milk as necessary. Season to taste and serve.
Notes
Make sure you choose a starchy or all-rounder potato for best results. See the notes in the post for more detail.
To make this soup vegan, simply omit the cream and use a plant based milk that works for your dietary requirements.
Blending potatoes gelatinises their starches. This will result in a gluey, gloopy soup. I HIGHLY recommend using a stick blender for this reason - you can blend the soup only as much as necessary, without overdoing it.
If you don't have a stick blender, you can also use a regular blender. You will need to let the soup cool though, otherwise it might explode in the blender. This is particularly important if you are using a NutriBullet, which has no air holes for steam to escape. If you use a NutriBullet, I recommend cooling the soup entirely before you blend.
Keep extra milk on hand than the recipe specifies in case you want to thin the soup out a little. If not, use water.
