  • 3 tablespoons quinoa
  • 6 tablespoons water
  • 20 white button or cremini mushrooms
  • 1/4 cup butter Substitute Olive oil for vegan option
  • 1/4 cup minced onion
  • 1/4 cup finely chopped pistachios
  • 3 tablespoons finely chopped fresh parsley
  • 1/4 teaspoon dried oregano
  • 1/2 teaspoon pepper sauce I use Frank's Buffalo Wing sauce or use Tabasco
  • 1/2 teaspoon salt
  • 1/4 cup plus 2 tablespoons freshly grated Parmesan cheese divided
  • Red pepper flakes optional


  • Preheat the oven to 400F degrees.
  • Bring the quinoa and water to a boil in a small saucepan. Cover, reduce to a simmer and cook for 10 minutes. Turn the heat off and leave the covered saucepan on the burner for another 4 minutes. Fluff with a fork and allow the quinoa to cool.
  • Gently twist the mushroom stems to remove them. Finely dice the stems. Melt the butter or olive oil in a small saucepan and sauté the stems and onion on medium heat until the onion is opaque and tender, 3 to 5 minutes. Remove from the heat and allow to cool.
  • Stir the quinoa, pistachios, parsley, oregano, pepper sauce, salt and 2 tablespoons of freshly grated Parmesan cheese into the mushroom and onion mixture. Using a teaspoon, scoop the filling into the mushroom caps and place them on a baking sheet. (They can be refrigerated at this point for up to 24 hours.)
  • Bake for 13-15 minutes, depending on their size, until the mushrooms are tender. Sprinkle with remaining Parmesan cheese. Add a dash of red pepper flakes, if desired. Serve warm.
