Ingredients Method Notes

Ingredients
  

  • 20 large button mushrooms stems removed and chopped
  • 8 oz 225 g cream cheese (softened)
  • 1 cup fresh spinach chopped
  • 1/2 cup Parmesan cheese grated
  • 1/4 cup breadcrumbs
  • 2 garlic cloves minced
  • 1 small onion finely chopped
  • 2 tbsp olive oil
  • 1 tsp dried oregano
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 1/4 tsp red pepper flakes optional
  • Fresh parsley for garnish

Method
 

  1. Prepare the Mushrooms: Gently wipe the mushrooms clean with a damp cloth. Remove and finely chop the stems. Hollow out the caps slightly.
  2. Sauté the Aromatics: Heat 1 tbsp olive oil in a skillet over medium heat. Add chopped mushroom stems, onion, and garlic. Sauté for about 5 minutes until onions are translucent.
  3. Wilt the Spinach: Stir in the chopped spinach and cook for another 2–3 minutes until wilted. Remove from heat and let cool slightly.
  4. Mix the Filling: In a large bowl, combine the softened cream cheese, sautéed mixture, Parmesan, breadcrumbs, oregano, salt, black pepper, and red pepper flakes. Mix well.
  5. Stuff the Mushrooms: Preheat oven to 375°F (190°C). Spoon or pipe the filling into each mushroom cap, slightly mounding it on top.
  6. Bake to Perfection: Place stuffed mushrooms on a lined baking sheet. Drizzle with the remaining 1 tbsp olive oil. Bake for 20–25 minutes until golden brown and tender.
  7. Garnish & Serve: Let mushrooms cool slightly before garnishing with fresh parsley. Serve warm and enjoy!

Notes

  • For extra crunch, sprinkle toasted breadcrumbs or crushed nuts on top before baking.
  • Add a splash of white wine while sautéing for enhanced flavor.
  • Experiment with different cheeses like mozzarella, feta, or goat cheese for a unique twist.
