Ingredients:
- 4 large portobello mushroom caps, stems and gills removed
- 2 tablespoons olive oil, divided
- 1 teaspoon minced garlic
- 1/2 cup finely chopped onion
- 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
Preparing the Portobellos
Preheating the Oven and Mushroom Prep
Preheat your oven to 375°F (190°C). This moderate temperature will allow the mushrooms to cook through and become tender without burning. Begin extract by preparing your portobello mushroom caps. Gently wipe the mushroom caps clean with a damp paper towel to remove any dirt or debris. Avoid washing them under running water, as mushrooms can absorb too much moisture, which can make them watery when cooked. Once clean, carefully snap off the stems. You can discard the stems or save them for another use, like making vegetable stock. Next, use a spoon to gently scrape out the dark gills from the underside of each mushroom cap. Removing the gills not only makes the mushroom look tidier but also prevents them from releasing excess moisture during baking. You can use the back of a spoon for this, being careful not to puncture the cap.
Cooking the Filling
Sautéing Aromatics and Spinach
In a medium skillet, heat 1 tablespoon of the olive oil over medium heat. Once the oil is shimmering, add the finely chopped onion. Sauté the onion for about 3-5 minutes, stirring occasionally, until it becomes softened and translucent. This process releases the sweet flavors of the onion and forms a delicious base for our filling. Add the minced garlic to the skillet and cook for another minute until fragrant. Be careful not to burn the garlic, as it can become bitter. Now, it’s time to add the fresh spinach. Add the roughly chopped spinach in batches if necessary, allowing each batch to wilt down before adding more. Stir the spinach with the onions and garlic until it has completely wilted, which should only take a couple of minutes. This step is crucial for concentrating the flavor of the spinach.
Creating the Creamy Cheese Mixture
Once the spinach has wilted, remove the skillet from the heat. This is important to prevent the cheese from becoming oily or clumping. In a medium bowl, combine the ricotta cheese and grated Parmesan cheese. Add the salt, black pepper, and the optional nutmeg. Nutmeg adds a lovely warmth and subtle complexity to the cheese filling, complementing the earthy mushrooms. Stir these ingredients together until well combined. Now, add the wilted spinach and onion mixture to the cheese. Gently fold the spinach mixture into the cheese, ensuring it’s evenly distributed. Finally, stir in the shredded mozzarella cheese. This mozzarella will provide a wonderfully gooey and cheesy element as the mushrooms bake. Taste the filling and adjust seasoning if needed.
Assembling and Baking
Stuffing and Baking the Mushrooms
Place the prepared portobello mushroom caps, gill-side up, on a baking sheet lined with parchment paper for easy cleanup. Drizzle the remaining 1 tablespoon of olive oil over the inside of each mushroom cap. This will help to season the mushrooms and add a little richness. Spoon the spinach and cheese filling generously into each portobello mushroom cap, mounding it slightly. You want to fill them as much as possible without the filling overflowing too much. Sprinkle a little extra grated Parmesan cheese over the top of each stuffed mushroom. This will create a lovely golden-brown crust as it bakes. Place the baking sheet in the preheated oven and bake for 20-25 minutes. The mushrooms should be tender, and the cheese topping should be melted and slightly golden.
Checking for Doneness and Serving
To check if the mushrooms are done, you can gently pierce the flesh of the mushroom cap with a fork; it should be tender. The cheese topping should be bubbling and have some nice golden-brown spots. If you prefer a more browned topping, you can briefly place the mushrooms under the broiler for the last minute or two, watching them very carefully to prevent burning. Once they are perfectly cooked, remove the stuffed portobello mushrooms from the oven. Let them rest for a few minutes before serving. This allows the filling to set slightly and makes them easier to handle. Serve these Spinach and Cheese Stuffed Portobello Mushrooms hot as a delicious appetizer or a satisfying vegetarian main course. They are wonderful on their own or served with a side salad.

Frequently Asked Questions:
Can I make these Spinach and Cheese Stuffed Portobello Mushrooms ahead of time?
Yes, you can assemble the stuffed mushrooms up to a day in advance. Store them covered in the refrigerator. When ready to bake, you may need to add a few extra minutes to the cooking time.
