Equipment

  • Food processor

Ingredients

  • 6 portobello mushrooms
  • 2 garlic cloves
  • 1/2 cup fresh basil (tightly packed)
  • 1/2 cup fresh parsley (tightly packed)
  • 3/4 cup walnuts
  • 1/2 cup gluten free oat flour (or substitute gluten free bread crumbs)
  • 1/4 cup extra virgin olive oil (plus 1 tablespoon extra for brushing the mushrooms)
  • 3/4 teaspoon salt
  • 1/4 teaspoon black pepper

Instructions

  • Preheat the oven to 375 degrees Fahrenheit.
  • Clean the portobello mushrooms by wiping them with a damp cloth.
  • Gently remove the stalk from the centre of the mushroom.
  • Use a spoon to scrape out the gills from each mushroom (reserve the gills to add to the stuffing mixture).
  • Use a basting brush to coat the tops and sides of the mushrooms with 1 tablespoon of extra virgin olive oil, making sure that all of the areas that won’t be stuffed are thoroughly coated with oil.
  • Add the gills from the mushrooms, garlic, basil, parsley, walnuts, gluten free oat flour, 1/4 cup olive oil, salt, and pepper to a food processor and process with several quick on/off pulses until everything is thoroughly mixed (alternatively, you could finely chop all the ingredients by hand and stir in a mixing bowl. I just prefer the time saver of the food processor).
  • Spoon the stuffing mixture into the mushrooms, making sure they are full but not overflowing.
  • Bake at 375 degrees Fahrenheit for 40 minutes.
  • Makes 6 vegan stuffed portobello mushrooms.

Notes

  • Serve warm, or store in an airtight container in the fridge for a few days and reheat before serving.
