# Expert Hints:

01 -
  • It transforms simple vegetables into something silky and satisfying without any fuss or fancy techniques.
  • The homemade croutons add a crunchy contrast that makes every spoonful feel complete.
  • You can make it as rich or as light as you want, depending on your mood and what's in the fridge.
  • It reheats beautifully, so you can enjoy it all week without it losing any charm.
02 -
  • Don't skip the potato, I tried making this without it once and the texture was watery and thin, it really needs that starch to feel luxurious.
  • Let the soup cool slightly before blending or you'll end up with hot soup all over your ceiling, I learned that one the hard way.
  • Taste the soup after blending and before adding milk, sometimes it needs more salt or a squeeze of lemon to brighten everything up.
03 -
  • If you want a deeper flavor, roast the cauliflower and broccoli in the oven before adding them to the pot, it adds a subtle caramelized sweetness.
  • Freeze individual portions in mason jars leaving an inch of space at the top, and you'll have homemade soup ready to go whenever you need it.
  • A squeeze of fresh lemon juice right before serving brightens the whole bowl and makes the vegetables taste more vibrant.
