Template more than recipe, Julia Child's leek and potato soup is nevertheless famous - and about 50% animal products (chicken stock and heavy whipping cream).
Neither, thankfully, is difficult to replace. Yet the dairy-free heavy whipping cream you use makes a big difference! Read my product review of substitutions to learn why I practically require Country Crock Homestyle for vegan vichyssoise.
Did you know that Goldfish were meant to be a bar snack? They were also one of Julia Child's favorite munchies! I don't know if she ever paired them with her vichyssoise, but I daresay she'd approve of this combination.

Simmer prepared vegetables in broth about 40 minutes, until very tender.
Using a blender, purée soup in batches. Transfer each batch of blended soup to another pot.
Stir in cream and seasonings. If serving chilled (as is traditional), slightly oversalt.
Chill if desired, then serve and sprinkle on chives.

Gratitude is the most scrumptious seasoning!
