"I adore Potato Leek soup, and this is the best recipe I've found so far after trying several!
A couple of edits:
1. I use all chicken stock instead of a mix of chicken and beef, and have made it using half stock/half water because sometimes it's too rich with all stock
2. I don't do the crispy leeks on top unless I'm serving for guests
3. You can add a touch of cream after pureeing if you want an even creamier soup. I've experimented with various levels of puree for different textures. Super easy with a hand-blender but also easy with an actual blender or a food processor.
4. The soup freezes great, made a big batch up it pre-baby and we defrosted and ate after Avery arrived - easy supper with grilled cheese on nice french or sour-dough bread!" - brookebass
