Step-by-Step Instructions
- Preheat & Prep the Mushrooms Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper. Gently wipe mushrooms clean with a damp paper towel. Remove stems and carefully scrape out the dark gills with a spoon (this prevents sogginess). Brush both sides with 2 Tbsp olive oil and season with salt & pepper. Place gill-side up on the baking sheet.

- Pre-Bake the Mushrooms Bake for 10 minutes to release moisture and soften slightly.
- Make the Spinach Filling While mushrooms bake, heat remaining 1 Tbsp olive oil in a large skillet over medium heat. Add minced garlic and sauté 30 seconds until fragrant. Add spinach and cook 2-3 minutes until wilted. Season with oregano, salt & pepper. Remove from heat and let cool slightly.
- Mix the Filling In a bowl, combine wilted spinach mixture with crumbled feta and parmesan (if using). Stir until creamy and well combined. Taste and adjust seasoning.
- Stuff the Mushrooms Remove mushrooms from oven (they will have released liquid – you can drain it). Generously mound the spinach-feta filling into each cap. Sprinkle with breadcrumbs if using.
- Bake Until Golden Return to oven and bake 15-18 minutes until the tops are golden and cheese is bubbly. For extra color, broil 1-2 minutes at the end (watch closely!).
- Rest & Serve Let cool 2 minutes. Serve hot straight from the oven!

Pro Tips for Mushroom Perfection
- Moisture control: Pre-baking + removing gills = no soggy mushrooms!
- Make ahead: Stuff the mushrooms up to 8 hours early, cover & refrigerate. Bake just before serving (add 3-5 extra minutes).

- Vegan version: Swap feta for vegan feta and skip parmesan.
- Leftovers: Store in airtight container up to 2 days. Reheat in oven at 350°F for best texture.
