# Expert Advice:

01 -
  • It turns everyday vegetables into something silky and comforting without any fancy ingredients.
  • The homemade croutons add a satisfying crunch that makes every spoonful feel complete.
  • You can blend it completely smooth or leave it chunky, depending on your mood.
  • It reheats beautifully, so leftovers taste just as good the next day.
02 -
  • Dont skip the potato, I tried it once and the soup was thin and watery instead of creamy and luxurious.
  • If you blend the soup while its still boiling hot, it can explode out of the blender, so let it cool for a minute or two first.
  • Add the milk after blending, not before, or it can curdle during the high heat simmer.
03 -
  • Roast the cauliflower and broccoli in the oven before adding them to the pot for a deeper, caramelized flavor.
  • Use an immersion blender if you have one, it saves time and keeps the cleanup minimal.
  • Freeze individual portions in mason jars, leaving space at the top for expansion, and youll have homemade soup ready whenever you need it.
