Step 1: Prepare the Mushrooms : Preheat oven to 375°F (190°C). Clean mushrooms with a damp cloth and remove stems. Lightly brush each mushroom cap with olive oil and arrange them on a baking tray lined with parchment paper.

Step 2: Make the Spinach Filling : In a skillet, heat 1 tablespoon olive oil over medium heat. Add minced garlic and sauté for about 30 seconds until fragrant. Add chopped spinach and cook until wilted (2–3 minutes). Transfer to a mixing bowl and allow to cool slightly. Add feta cheese, cream cheese, Parmesan, dill/parsley, salt, pepper, and chili flakes. Mix well until creamy and evenly combined.

Step 3: Stuff the Mushrooms : Spoon the spinach-feta mixture into each mushroom cap, pressing lightly to fill. Sprinkle breadcrumbs on top for extra crunch (optional). Drizzle with a little olive oil for a golden finish.

Step 4: Bake : Bake in the preheated oven for 18–20 minutes, or until mushrooms are tender and tops are slightly golden. Remove from oven and let cool for 5 minutes before serving.
