Helpful Recipe Tips

  • Avoid chopping mushrooms or onions up too finely. What will happen is they will get mushy and you want to still have a bite to the vegetables.
  • Keep moisture in the pan. Throughout cooking the pan can start to look dry. When this happens don't add the butter in, add in a bit more olive oil.
  • Make sure you allow moisture to evaporate from the mushrooms before adding the oil or onions. If you leave a bunch of water in they won't sauté as well, they will steam more and the recipe will end up being more soupy than creamy in the end. See video below for assistance.
