Instructions

  1. Preheat Oven: Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Line a sided baking sheet with parchment paper to prepare for baking the mushrooms.
  2. Prepare Mushrooms: Using a small spoon, gently scoop out the gills from the inside of each portabella mushroom. With a small knife, carefully remove the mushroom stalks. Rub each mushroom lightly with olive oil and place them on the prepared baking sheet, stalk side up.
  3. Sauté Vegetables: Heat 2 tablespoons of olive oil in a 12-inch sauté pan over medium-high heat. Add the diced sweet onion and sauté for 3 to 4 minutes until translucent. Add the diced zucchini and cook until it begins to soften. Stir in the diced roasted red pepper and chopped sun-dried tomatoes, cooking for a few more minutes.

  5. Stuff Mushrooms: Divide the vegetable mixture into four equal portions. Spread the mixture evenly in the pan and slice like a pie into quarters with a spoon. Spoon each quartered mixture evenly into each prepared portabella mushroom cap.
  6. Bake Mushrooms: Place the stuffed mushrooms in the preheated oven and bake for about 35 to 40 minutes.
