Description

These Stuffed Portobello Mushrooms are hearty, flavorful, and versatile — perfect as a vegetarian main or a savory side dish. Filled with a mixture of vegetables, breadcrumbs, herbs, and melted cheese, they’re baked until golden and satisfying with every bite.


Ingredients

Scale
  • 4 large portobello mushrooms, stems removed and gills scraped
  • 2 tablespoons olive oil, divided
  • 1 small onion, finely diced
  • 2 garlic cloves, minced
  • 1 small red bell pepper, diced
  • 1 small zucchini, diced
  • ½ teaspoon dried oregano
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • ½ cup breadcrumbs (panko or regular)
  • ½ cup shredded mozzarella cheese
  • ¼ cup grated Parmesan cheese
  • 2 tablespoons fresh parsley, chopped (for garnish)

Instructions

  1. Preheat oven to 375°F (190°C) and line a baking sheet with parchment paper.
  2. Brush portobello caps with 1 tablespoon olive oil on both sides and place them gill-side up on the baking sheet.
  3. In a skillet, heat the remaining olive oil over medium heat. Sauté onion, garlic, bell pepper, and zucchini until softened, about 5 minutes. Season with oregano, salt, and pepper.
  4. Remove skillet from heat and stir in breadcrumbs, mozzarella, and Parmesan until well combined.
  5. Spoon the filling evenly into the mushroom caps.
  6. Bake for 20–25 minutes, until mushrooms are tender and cheese is melted and golden.
  7. Garnish with fresh parsley and serve warm.

Notes

  • Add spinach or kale to the filling for extra greens.
  • Make it vegan by using dairy-free cheese and nutritional yeast instead of Parmesan.
  • Top with marinara sauce for an Italian-inspired twist.
  • For extra protein, stir in cooked quinoa or lentils to the filling.
