Ingredients

Scale

Main Protein and Vegetables:

  • 4 large portobello mushrooms
  • 1 cup baby spinach, chopped
  • 1/2 bell pepper, diced
  • 1/2 small onion, finely chopped
  • 1/2 cup cherry tomatoes, quartered

Cheese and Dairy:

  • 1/2 cup shredded mozzarella cheese

Seasonings and Oils:

  • 1 tablespoon olive oil
  • 2 cloves garlic, minced
  • Salt and pepper, to taste
  • Fresh parsley or basil for garnish (optional)

Instructions

  1. Sanitize portobello mushrooms thoroughly using a moist cloth, carefully eliminating stems and inner gills, creating a clean vessel for stuffing.
  2. Activate a skillet on medium temperature, drizzle olive oil, and introduce minced garlic and diced onions, developing aromatic flavors for 2-3 minutes until translucent.
  3. Incorporate bell peppers into the skillet, sautéing an additional 2-3 minutes to enhance vegetable tenderness and caramelize edges.
  4. Fold baby spinach and cherry tomatoes into the mixture, allowing greens to wilt and tomatoes to release subtle juices, seasoning with salt and pepper for depth.
  5. Arrange mushroom caps gill-side upward on a parchment-lined baking sheet, ensuring even spacing for consistent cooking.
  6. Generously distribute prepared vegetable mixture into each mushroom cap, pressing gently to create a compact filling.
  7. Cascade shredded mozzarella across the stuffed mushrooms, creating a melting cheese layer.
  8. Slide baking sheet into a preheated 375°F (190°C) oven, roasting 15-20 minutes until mushrooms turn tender and cheese transforms into a golden, bubbling crust.
  9. Remove from oven, allowing brief cooling period, then garnish with fresh parsley or basil for vibrant presentation.
  10. Serve immediately while ingredients maintain optimal temperature and texture.

Notes

  • Opt for firm, fresh portobello mushrooms without bruises or soft spots to ensure a perfect texture and prevent soggy results.
  • Choose full-sized mushrooms with deep caps to maximize filling potential and create a hearty, satisfying meal.
  • Gently pat mushrooms dry after cleaning to prevent excess moisture that could make the dish watery during baking.
  • Swap out mozzarella for dairy-free alternatives like nutritional yeast or vegan cheese to accommodate plant-based diets.
