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
- Start by preparing your portobello mushroom caps. Gently wipe them clean with a damp paper towel to remove any dirt or debris. Be careful not to wash them under running water, as they can absorb too much moisture. Carefully snap off the stems by wiggling them back and forth. Next, use a spoon to gently scrape out the dark gills from the underside of each mushroom cap. This step is optional, but it removes a slightly bitter flavor and creates a cleaner appearance for the stuffed mushrooms. You want to have nice, clean bowls ready to be filled.
- Once your mushroom caps are prepped, it’s time to give them a head start in the oven. Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Place the mushroom caps, gill-side up, on a baking sheet. Drizzle about 1 tablespoon of olive oil evenly over the inside of each cap, ensuring they are lightly coated. This will help them soften and prevent them from drying out during the initial baking phase. Bake them for about 10 minutes while you prepare the filling. This brief bake also helps release some of the moisture from the mushrooms.
Crafting the Savory Filling
- While the mushrooms are pre-baking, let’s make the delicious filling. Heat the remaining 1 tablespoon of olive oil in a medium skillet over medium heat. Add the finely chopped onion and sauté until it becomes softened and translucent, which should take about 3-5 minutes. Stir in the minced garlic and cook for another minute until fragrant, being careful not to burn it. If you’re using nutmeg, add it now to allow its aroma to bloom in the hot oil.
- Add the roughly chopped fresh spinach to the skillet with the onions and garlic. It might seem like a lot of spinach, but it will wilt down considerably. Cook, stirring frequently, until the spinach is completely wilted, which usually takes about 2-3 minutes. Once wilted, remove the skillet from the heat. This prevents the spinach from becoming overcooked and mushy.
- In a medium bowl, combine the ricotta cheese and the 1/4 cup of grated Parmesan cheese. Add the salt and black pepper, and mix everything together until well combined. Now, stir in the wilted spinach and onion mixture from the skillet into the cheese mixture. Fold it gently until everything is evenly distributed. This creates a creamy, flavorful base for our stuffed mushrooms.
Assembling and Baking to Perfection
- After the initial 10-minute bake, carefully remove the mushroom caps from the oven. Spoon the spinach and cheese filling generously into each of the pre-baked portobello mushroom caps, dividing it as evenly as possible. Don’t be shy with the filling; you want them to be nicely mounded.
- Once filled, sprinkle the shredded mozzarella cheese over the top of the filling in each mushroom cap. The mozzarella will melt and become wonderfully gooey, creating a beautiful golden-brown topping. For an extra touch of flavor and to enhance the presentation, you can sprinkle a little extra grated Parmesan cheese over the mozzarella.
- Return the baking sheet with the stuffed mushrooms to the preheated oven. Bake for another 15-20 minutes, or until the mushrooms are tender and the mozzarella cheese is melted, bubbly, and lightly golden. Keep an eye on them during the last few minutes to ensure the cheese doesn’t burn. The aroma that fills your kitchen will be absolutely divine! Let them rest for a few minutes on the baking sheet before serving, allowing the filling to set slightly.
