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 the Oven and Preparing the Mushroom Caps

Let’s get started by preheating our oven to a cozy 375°F (190°C). This gentle heat will ensure our stuffed mushrooms cook through beautifully without drying out. Next, we need to prepare our portobello mushroom caps. Gently wipe the mushroom caps clean with a damp paper towel. You want to remove any dirt or debris, but avoid washing them under running water as they can absorb too much moisture. Using a spoon, carefully scrape out the dark gills from the underside of each mushroom cap. These gills can have a slightly bitter taste and a softer texture, so removing them makes for a cleaner, more pleasant bite and creates a perfect little bowl for our delicious filling. You can discard the gills or save them for making vegetable broth if you like. Now, place the prepared mushroom caps, gill-side up, on a baking sheet. Drizzle about half a tablespoon of olive oil evenly over the inside and outside of each mushroom cap. This simple step helps them roast slightly and adds a lovely flavor. Season the inside of each cap with a tiny pinch of salt and pepper – just enough to enhance the mushroom’s natural taste.

Creating the Flavorful Spinach and Cheese Filling

Step 2: Sautéing the Aromatics

Now, let’s move on to creating the heart of our Spinach and Cheese Stuffed Portobello Mushrooms: the irresistible filling. Heat the remaining 1 and a half tablespoons of olive oil in a large skillet over medium heat. Once the oil is shimmering, add your finely chopped onion. Sauté the onion for about 3-4 minutes, stirring occasionally, until it becomes translucent and tender. We’re not looking for browning here, just a gentle softening to release its sweetness. Next, add the minced garlic to the skillet. Cook for another minute, until fragrant. Be careful not to burn the garlic, as this can turn it bitter. We want that lovely, pungent aroma to infuse the oil.

Step 3: Wilting the Spinach and Incorporating the Cheeses

Add the roughly chopped fresh spinach to the skillet with the onions and garlic. It might look like a lot of spinach at first, but don’t worry – it will wilt down considerably. Stir the spinach constantly for about 2-3 minutes until it has completely softened and reduced in volume. This process of wilting removes excess moisture from the spinach, which is important to prevent a watery filling. Once the spinach is wilted, remove the skillet from the heat. This prevents the cheeses from becoming oily. Now, add the ricotta cheese and the grated Parmesan cheese to the skillet. Season with salt, black pepper, and the optional nutmeg, if you’re using it. Nutmeg adds a warm, slightly sweet, and earthy note that pairs wonderfully with spinach and cheese. Stir everything together until the cheeses are well combined and the spinach is evenly distributed throughout the creamy mixture. Taste a tiny bit (carefully, it’s hot!) and adjust seasoning if needed.

Assembling and Baking the Stuffed Mushrooms

Step 4: Stuffing the Portobello Caps

Now for the fun part – assembling our stuffed mushrooms! Take your prepared portobello mushroom caps from the baking sheet and carefully spoon the spinach and cheese filling into each one. Don’t be shy; generously mound the filling into the cavity of each mushroom, pressing it down gently. You want to fill them right up to the brim, creating a beautiful, overflowing presentation. For an extra layer of cheesy goodness and a lovely golden-brown topping, sprinkle the shredded mozzarella cheese evenly over the top of the filling in each mushroom. And if you like, you can also add a little extra grated Parmesan cheese over the mozzarella for an even richer flavor and a wonderfully crisp crust.

Step 5: Baking to Perfection

Carefully place the baking sheet with the stuffed portobello mushrooms back into the preheated oven. Bake for 20-25 minutes, or until the mushrooms are tender and the cheese topping is melted, bubbly, and lightly golden brown. The exact baking time will depend on the size of your mushroom caps and how juicy they are. You’ll know they’re ready when the mushroom edges are slightly softened and the filling is heated through. Once they’re done, carefully remove the baking sheet from the oven. Let the stuffed mushrooms rest for a few minutes before serving. This allows the flavors to meld and makes them easier to handle. They are best enjoyed hot, straight from the oven.
