  • 1 teaspoon dried Italian seasoning or mix of oregano, basil, thyme

Optional Additions

Equipment

  • Baking sheet
  • skillet,
  • Mixing bowl

Method
 

  1. Gently clean the mushroom caps with a damp paper towel and remove the stems. Scrape out the gills using a spoon. Place caps gill-side up on a baking sheet, drizzle with 1 tablespoon olive oil, season with salt and pepper, and set aside.
  2. Heat remaining 1 tablespoon olive oil in a skillet over medium heat. Add diced onion and cook 3-5 minutes until soft and translucent.
  3. Add minced garlic and diced bell pepper to skillet. Cook for 3-4 minutes until bell pepper softens. Add any additional vegetables like spinach and cook until tender and moisture evaporates.
  4. Remove skillet from heat. In a bowl, combine sautéed vegetables with breadcrumbs, Parmesan, mozzarella, cream cheese, parsley, and Italian seasoning.
  5. Season filling with salt and pepper. Taste and adjust seasonings. Add optional ingredients like sausage or sun-dried tomatoes. Mix well until combined and moist but not wet.
  6. Spoon the filling into each mushroom cap, mounding slightly and pressing down lightly to compact.
  7. Optionally, sprinkle extra Parmesan or mozzarella on top for a golden crust.
  8. Bake in a preheated oven at 350°F (175°C) for 20-25 minutes until mushrooms are tender, filling is heated through, and cheese is bubbly and golden.
  9. Remove from oven and let rest a few minutes before serving warm as an appetizer, side, or main dish.
