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

Start by preparing your portobello mushroom caps. Gently wipe them clean with a damp paper towel to remove any dirt. If there are any stubborn bits of soil, you can use a small brush or even a spoon to carefully scrape them away. Next, you’ll want to remove the stems. These are usually quite easy to pull out with your fingers. Once the stems are removed, locate the dark, feathery gills on the underside of the mushroom cap. You can use a spoon to carefully scrape these out. Removing the gills is not strictly necessary, but it creates more space for your delicious filling and also prevents the mushrooms from releasing too much excess moisture while baking, which can make the filling watery. Once prepped, set the mushroom caps aside.
In a medium skillet, heat 1 tablespoon of the olive oil over medium heat. Add the finely chopped onion and sauté for about 5-7 minutes, or until the onion is softened and translucent. You’re looking for a nice, gentle cook here, not browning. This process will release the natural sweetness of the onion and build a flavorful base for our filling. Once the onion is tender, add the minced garlic and cook for another minute until fragrant. Be careful not to burn the garlic, as it can become bitter.
Now it’s time to wilt the spinach. Add the roughly chopped fresh spinach to the skillet with the onions and garlic. Stir it in and cook for about 2-3 minutes, or until the spinach has completely wilted down. You might need to do this in batches if your skillet is not very large, to avoid overcrowding. Once wilted, remove the skillet from the heat. This step is crucial because cooking the spinach beforehand helps to remove excess moisture, which, again, prevents a soggy filling.
In a medium bowl, combine the ricotta cheese and the grated Parmesan cheese. Add the salt, black pepper, and nutmeg (if you’re using it – it adds a lovely subtle warmth and depth of flavor that pairs beautifully with spinach and cheese). Stir these ingredients together until they are well combined. Then, add the wilted spinach and onion mixture from the skillet into the bowl with the cheeses. Mix everything thoroughly until all the ingredients are evenly distributed. This creates your luscious, flavorful stuffing.
Preheat your oven to 375°F (190°C). Brush the inside and outside of each portobello mushroom cap with the remaining 1 tablespoon of olive oil. This will help the mushrooms cook evenly and develop a lovely slightly crisp texture on the edges. Place the prepared mushroom caps, gill-side up (or cavity-side up), onto a baking sheet. Evenly divide the spinach and cheese filling among the four mushroom caps, spooning it generously into each cavity. Make sure to press the filling down slightly to compact it. Finally, sprinkle the shredded mozzarella cheese evenly over the top of the filling in each mushroom. You can also add a little extra grated Parmesan on top for an extra cheesy crust.

Baking and Serving

Place the baking sheet with the stuffed portobellos into the preheated oven. Bake for 20-25 minutes, or until the mushrooms are tender and the mozzarella cheese on top is melted, bubbly, and lightly golden brown. The cooking time can vary slightly depending on the size of your mushrooms and your oven. Keep an eye on them during the last few minutes to ensure the cheese doesn’t burn.
Once baked to perfection, carefully remove the baking sheet from the oven. Let the Spinach and Cheese Stuffed Portobello Mushrooms rest for a few minutes before serving. This allows the flavors to meld together and the filling to set slightly, making them easier to handle and enjoy. They are wonderful served as a hearty appetizer or as a satisfying vegetarian main course. Garnish with a sprinkle of fresh parsley or a touch more grated Parmesan, if desired.
