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 Portobello Mushrooms
Step 1: Preheating and Preparing the Mushrooms
Begin extract by preheating your oven to 375°F (190°C). This ensures the mushrooms cook evenly and the filling gets nice and bubbly. Next, we need to prepare our portobello mushroom caps. Gently wipe the mushroom caps with a damp paper towel to remove any dirt. Be careful not to wash them under running water, as they can absorb too much moisture and become soggy. Carefully snap off the stems. You can discard the stems or save them for another use, like a vegetable stock. Then, using a spoon, gently scrape out the dark gills from the underside of each mushroom cap. This step is optional for some, but it removes a slightly bitter element and creates more space for our delicious filling. Once prepped, place the mushroom caps, cavity-side up, on a baking sheet. Drizzle about 1 teaspoon of olive oil over the inside of each mushroom cap and season lightly with a pinch of salt and pepper. This initial seasoning helps to enhance the natural flavor of the mushrooms.
Creating the Savory Filling
Step 2: Sautéing Aromatics and Spinach
Now, let’s get started on the flavorful filling. Heat the remaining olive oil (about 1 tablespoon) in a large skillet over medium heat. Once the oil is shimmering, add the finely chopped onion and cook, stirring occasionally, until it becomes softened and translucent, which should take about 5-7 minutes. We want to draw out the sweetness of the onion without letting it brown too much. Add the minced garlic to the skillet and cook for another minute until fragrant. Be mindful not to burn the garlic, as it can turn bitter. Now it’s time for the spinach. Add the roughly chopped fresh spinach to the skillet. It might seem like a lot of spinach, but it will wilt down considerably. Stir the spinach into the onion and garlic mixture and cook until it has completely wilted, which usually takes just a couple of minutes. If there’s excess liquid released from the spinach, you can gently press it with your spoon to remove some of it before proceeding. This helps to prevent the filling from becoming watery.
Step 3: Combining the Filling Ingredients
Once the spinach has wilted, remove the skillet from the heat. This cooling period is important before adding the cheese, as we don’t want the ricotta to become too oily. In a medium bowl, combine the ricotta cheese and the grated Parmesan cheese. Add the sautéed onion and spinach mixture to the bowl. Season the filling with 1/4 teaspoon of salt and 1/4 teaspoon of black pepper. If you’re using it, now is the time to add the 1/4 teaspoon of nutmeg. Nutmeg adds a wonderful warmth and complexity to cheesy dishes, so I highly recommend it if you have it on hand. Stir everything together thoroughly until all the ingredients are well combined and you have a creamy, cohesive filling. Taste a small spoonful of the filling (careful, it might be warm!) and adjust the salt and pepper if needed. Remember, the Parmesan cheese is already salty, so you might not need much additional salt.
Assembling and Baking the Stuffed Mushrooms
Step 4: Stuffing the Mushroom Caps
Now for the fun part – filling our portobello mushrooms! Generously spoon the spinach and cheese mixture into each prepared mushroom cap, mounding it slightly in the center. Don’t be shy; pack the filling in there so each bite is full of flavor. After filling each mushroom cap, evenly sprinkle the 1/2 cup of shredded mozzarella cheese over the top of the filling. The mozzarella will melt and become wonderfully gooey, creating a lovely cheesy crust. For an extra touch of flavor and presentation, you can sprinkle a little additional grated Parmesan cheese over the mozzarella. This adds another layer of savory goodness and a nice golden-brown finish. Ensure the filling is evenly distributed and the mozzarella covers the surface for optimal melting.
Step 5: Baking to Golden Perfection
Carefully place the filled portobello mushrooms back onto the baking sheet. Transfer the baking sheet to the preheated oven. Bake for approximately 20-25 minutes, or until the mushrooms are tender and the mozzarella cheese on top is melted, bubbly, and lightly golden brown. The exact baking time can vary depending on the size of your mushrooms and your oven’s performance. Keep an eye on them during the last few minutes of cooking to prevent the cheese from burning. If the tops start to brown too quickly, you can loosely tent the baking sheet with aluminum foil. Once they are ready, carefully remove the baking sheet from the oven. Let the stuffed portobello mushrooms rest for a few minutes before serving. This allows the filling to set slightly and makes them easier to handle. They are best enjoyed warm, perhaps with a sprinkle of fresh parsley for a pop of color and freshness.
