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
Preparation and Sautéing the Filling
-
Begin extract by preparing your portobello mushrooms. Gently wipe the mushroom caps clean with a damp paper towel to remove any dirt or debris. Carefully remove the stems by wiggling them gently until they detach. For a neater appearance and easier filling, you can also scrape out the dark gills from the underside of the mushroom caps using a spoon. This step is optional but recommended for a more refined presentation and a cleaner eating experience. Set the prepared mushroom caps aside.
Next, we’ll build the flavorful filling. Heat 1 tablespoon of the olive oil in a medium skillet over medium heat. Once the oil is shimmering, add the finely chopped onion. Sauté the onion for about 5-7 minutes, stirring occasionally, until it becomes softened and translucent. You want to achieve a nice sweetness from the onions without them browning too much.
Add the minced garlic to the skillet with the onions and cook for another minute until fragrant. Be careful not to burn the garlic, as this can impart a bitter flavor. Now, 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 constantly until it wilts completely, which usually takes about 2-3 minutes.
Once the spinach has wilted, remove the skillet from the heat. This is crucial to prevent overcooking the spinach and to make the filling easier to handle. Transfer the sautéed onion, garlic, and spinach mixture to a medium bowl. Allow it to cool slightly for a few minutes.
To this cooled vegetable mixture, add the ricotta cheese, grated Parmesan cheese, salt, black pepper, and the nutmeg if you are using it. Stir everything together gently until well combined. The ricotta will provide a creamy base, the Parmesan will add a savory, nutty depth, and the salt, pepper, and nutmeg will enhance the overall flavor profile. Taste the mixture and adjust seasonings if needed. Remember, the mozzarella will add more saltiness later, so don’t over-salt at this stage.
-
Now it’s time to stuff our beautiful portobello mushrooms. Preheat your oven to 375°F (190°C). Lightly brush the outsides of the prepared portobello mushroom caps with the remaining 1 tablespoon of olive oil. This will help them roast nicely and prevent them from drying out. Place the oiled mushroom caps, cavity side up, on a baking sheet lined with parchment paper for easy cleanup.
Carefully spoon the spinach and cheese filling into each portobello mushroom cap. You want to generously fill each cap, mounding the filling slightly in the center. Don’t be shy with the filling; it’s what makes these mushrooms so delicious! Ensure the filling is evenly distributed among all four mushroom caps.
Once the mushrooms are stuffed, it’s time for the final cheesy touch. Sprinkle the shredded mozzarella cheese evenly over the top of the filling in each mushroom cap. The mozzarella will melt and become wonderfully gooey, creating a delicious golden-brown crust as the mushrooms bake. For an extra touch of flavor and visual appeal, you can also sprinkle a little extra grated Parmesan cheese over the mozzarella.
-
Place the baking sheet with the stuffed portobello mushrooms into the preheated oven. Bake for 20-25 minutes, or until the mushrooms are tender and the cheese on top is melted, bubbly, and lightly golden brown. The exact baking time will depend on the size of your mushrooms and your oven. Keep an eye on them to prevent the cheese from burning. The mushroom caps should feel tender when pierced with a fork.
If you want your cheese to be more deeply browned, you can briefly place the mushrooms under the broiler for the last 1-2 minutes of baking. Watch them very closely during this stage, as broilers can quickly turn cheese from golden to burnt.
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 filling to set slightly and makes them easier to handle.
Serve these delightful stuffed mushrooms hot as a main course, a hearty appetizer, or a delicious side dish. They pair wonderfully with a fresh green salad or roasted vegetables. Enjoy the rich flavors and satisfying texture of this simple yet elegant dish.
