Note
  • Mushrooms are like sponges: If you submerge them in water or even just run water over them, you’ll risk them becoming tough and tasteless. Baking the mushrooms first removes excess liquid.
  • If you have frozen veggies, ensure to squeeze out the excess moisture from them to avoid a watery filling.
  • Don’t skip the step of removing excess water from the mushrooms.
  • Feel free to garnish the mushrooms with fresh herbs, such as chopped parsley or basil before serving for added flavor and visual appeal.
