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: Prepare the Mushroom Caps
Begin extract by preparing your 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 mushrooms are like sponges and can absorb too much moisture, which can make them soggy. Next, carefully remove the stems by wiggling them gently until they detach. You’ll also want to scrape out the dark gills from the underside of the mushroom caps using a spoon. This step is purely for aesthetic reasons and to create more room for your delicious stuffing, but it definitely makes for a more elegant presentation. Once prepped, place the mushroom caps on a baking sheet, gill-side up, ready to be filled.
Making the Spinach and Cheese Filling
Step 2: Sauté the Aromatics
Now, let’s get started on the flavorful filling. Heat one tablespoon of the olive oil in a medium skillet over medium heat. Add the finely chopped onion to the hot skillet and cook, stirring occasionally, until the onion becomes soft and translucent, which should take about 5-7 minutes. You’re looking for a gentle sweetness to develop. Once the onion is softened, add the minced garlic to the skillet and cook for another minute until fragrant. Be careful not to burn the garlic, as this can impart a bitter flavor.
Step 3: Wilt the Spinach
Add the roughly chopped fresh spinach to the skillet with the sautéed onions and garlic. You might think there’s a lot of spinach, but it will wilt down considerably as it cooks. Stir the spinach into the onion and garlic mixture and cook until it’s just wilted, which usually takes about 2-3 minutes. Remove the skillet from the heat and let the spinach mixture cool slightly. This is important because you don’t want to add piping hot ingredients to the cheeses, which can cause them to become oily.
Step 4: Combine the Filling Ingredients
In a medium bowl, combine the ricotta cheese and the grated Parmesan cheese. Add the slightly cooled spinach and onion mixture to the cheese. Season this mixture with salt, black pepper, and the nutmeg, if you’re using it. Nutmeg adds a lovely warm depth to cheesy dishes, and it pairs wonderfully with spinach and mushrooms. Stir everything together until it’s well combined. Make sure to taste the filling at this point and adjust the seasonings if needed. Remember, the mushrooms themselves don’t have a strong flavor, so your filling needs to be well-seasoned.
Stuffing and Baking the Portobellos
Step 5: Stuff and Bake the Mushrooms
Now for the best part – stuffing the mushrooms! Divide the spinach and cheese filling evenly among the four prepared portobello mushroom caps, pressing it gently into the cavities. Make sure to mound the filling slightly so it looks abundant. Sprinkle the shredded mozzarella cheese evenly over the top of each stuffed mushroom. Drizzle the remaining one tablespoon of olive oil over the stuffed mushrooms. Preheat your oven to 375°F (190°C). Place the baking sheet with the stuffed mushrooms into the preheated oven and 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 how tender you prefer them. For an extra touch, you can sprinkle a little more grated Parmesan cheese over the mushrooms during the last 5 minutes of baking. Allow them to cool for a few minutes before serving.
