Ingredients Notes

Mushroom Caps (12 medium): Cremini or button, stems removed; uniform for even baking.
Spinach (2 cups, fresh): Baby spinach for tenderness; frozen if thawed and drained.
Feta Cheese (½ cup, crumbled): Tangy and creamy; goat cheese as alternative.
Garlic (2 cloves, minced): Fresh for bold aroma; powder (½ tsp) as substitute.
Olive Oil (2 tbsp): Extra virgin for sautéing and drizzling; enhances flavor.
Onion (¼ cup, finely chopped): Yellow for sweetness; shallots for milder taste.
Parmesan (2 tbsp, grated, optional): Adds nutty topping; omit for less richness.
Thyme (½ tsp, fresh or ¼ tsp dried): Earthy herb; oregano or rosemary as options.
Salt and Pepper (to taste): Enhances flavors; season spinach lightly due to feta’s saltiness.
Lemon Zest (½ tsp, optional): Brightens filling; fresh for best flavor.
