Haven't found anything better, especially after going vegan. Liked it enough I ate it for two weeks straight making multiple batches
When i was 15-16 I cooked quite possibly the best potato and leek soup I have ever had to this day. This was not only the best potato and leak soup but the best soup I have ever had. I have tried to replicate it repeatedly over the years and have never succeeded. To this day I crave that soup. The recipe was a fucking gif on reddit and I have never seen it since.
I made this one once and it was great

Not vegan, as it contains chicken stock and cream. You can easily replace the chicken stock with vegetable stock, but idk what to replace cream with. This soup rules and everyone I’ve served it to has loved it. Straining the blended soup through a fine mesh strainer isn’t technically necessary, but it makes the texture so much better. You don’t need an immersion blender if you don’t have one, as you can ladle it into a regular blender, although you’re gonna need to wash more bowls, but it saves a lot of steps.
It’s good hot or cold (although you’re gonna want to add a little more salt if you’re going to serve it cold).
