How to Make Spinach & Cheese Stuffed Portobellos
1. Preheat the Oven
Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper or foil.
2. Prepare the Mushrooms
Clean mushroom caps with a damp cloth. Remove stems and scrape out gills with a spoon if desired. Brush lightly with olive oil and place gill‑side up on the baking sheet.
3. Pre‑Roast the Mushrooms
Roast for 5–7 minutes to soften slightly and release excess moisture.
4. Make the Filling
In a skillet, heat 1 tablespoon olive oil over medium heat. Add garlic and cook for 1 minute. Stir in chopped spinach and cook until wilted. Transfer to a bowl and mix with ricotta, half of the mozzarella, Parmesan, salt, pepper, and red pepper flakes.
5. Fill and Bake
Remove mushrooms from the oven. Spoon the spinach mixture into each cap, top with the remaining mozzarella, and bake for 12–15 minutes until cheese is melted and bubbly.
6. Serve
Remove from the oven and let cool slightly. Garnish with fresh parsley or extra Parmesan before serving.
Leftovers and Storage
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven or air fryer until warmed through.
Avoid freezing, as mushrooms can become watery after thawing.
Nutrition & Benefits
Portobello mushrooms are a great source of fiber, B vitamins, and antioxidants, while spinach adds iron and vitamin K.
The cheese provides calcium and protein, making this a balanced and satisfying vegetarian dish.
