- 2 tablespoons olive oil
For the Filling
- 1 teaspoon garlic (minced)
- 1/2 cup onion (finely chopped)
- 2 cups fresh spinach (roughly chopped)
- 1/2 cup ricotta cheese
- 1/4 cup grated Parmesan cheese (plus extra for garnish)
- 1/4 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon nutmeg (optional)
- 1/2 cup shredded mozzarella cheese
For Garnish
- 2 tablespoons fresh parsley, finely chopped

How to Make Spinach and Cheese Stuffed Portobello Mushroom
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper. This will prepare your oven for baking the stuffed mushrooms evenly.
Step 2: Prepare the Mushroom Caps
Brush both sides of the mushroom caps with olive oil. Place them gill-side up on the baking sheet. Bake for about 10 minutes, or until they start to release water.
Step 3: Sauté Garlic and Onion
In a large skillet over medium heat, heat the remaining olive oil. Add the garlic and onion, sautéing until softened, about 3-4 minutes.
Step 4: Cook Spinach
Add the spinach to the skillet. Cook it until wilted, approximately 2-3 minutes. Once ready, remove the skillet from heat and let it cool slightly.
Step 5: Mix Filling Ingredients
In a mixing bowl, combine the sautéed spinach mixture with ricotta cheese, Parmesan cheese, salt, pepper, and nutmeg. Mix well until everything is combined.
Step 6: Fill Mushroom Caps
Spoon the cheese and spinach mixture evenly into each mushroom cap. Top each filled cap with shredded mozzarella cheese.
Step 7: Bake Again
Bake in your preheated oven for another 15-20 minutes or until the cheese is bubbly and golden brown.
Step 8: Garnish & Serve
Garnish with additional grated Parmesan cheese before serving. Enjoy your delicious Spinach and Cheese Stuffed Portobello Mushrooms!

Common Mistakes to Avoid
When making Spinach and Cheese Stuffed Portobello Mushrooms, it’s easy to overlook certain details. Here are some common mistakes and how to avoid them.
- Ignoring Mushroom Preparation: Failing to remove the stems and gills can lead to a soggy dish. Always clean the portobello caps properly for the best texture.
- Overcooking Spinach: Cooking spinach for too long can cause it to lose its nutrients and flavor. Sauté it just until wilted for maximum taste.
- Skipping Seasoning: Not seasoning the filling adequately can result in bland mushrooms. Use salt, pepper, and nutmeg to enhance the flavor of your stuffed mixture.
- Using Cold Ingredients: Starting with cold cheese can make mixing difficult. Let the ricotta and other cheeses come to room temperature for easier blending.
- Not Preheating the Oven: Skipping the preheating step may lead to uneven cooking. Always preheat your oven before baking for consistent results.
- Rushing the Baking Time: Underbaking can leave your cheese unmelty and mushrooms undercooked. Monitor closely during the final bake to achieve that golden brown finish.
Refrigerator Storage
- Store leftover stuffed mushrooms in an airtight container.
- They will last up to 3-4 days in the refrigerator.
- Keep them away from strong-smelling foods to prevent odor transfer.
Freezing Spinach and Cheese Stuffed Portobello Mushroom
- Wrap each stuffed mushroom tightly in plastic wrap before placing them in a freezer bag.
- They can be frozen for up to 2-3 months.
- Label your containers with dates for easy tracking.
Reheating Spinach and Cheese Stuffed Portobello Mushroom
- Oven: Preheat your oven to 350°F (175°C) and bake for 15-20 minutes until heated through.
- Microwave: Place on a microwave-safe plate and heat in short intervals, about 1-2 minutes, checking frequently.
- Stovetop: Heat on low in a skillet with a splash of water, covering it with a lid until warmed through.
