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 Portobellos
Step 1: Clean and Prep the Mushroom Caps
The first step to creating these delicious Spinach and Cheese Stuffed Portobello Mushrooms is to prepare the star of the show: the portobellos. Gently wipe down the mushroom caps with a damp paper towel to remove any dirt or debris. Avoid washing them under running water, as mushrooms can absorb excess moisture, which might make them watery when cooked. Once clean, carefully remove the stems by wiggling them back and forth until they detach. You’ll also want to remove the dark gills from the underside of the caps. You can do this with a spoon; gently scrape them out. Removing the gills not only makes for a cleaner presentation but also prevents the stuffing from becoming muddy in color. You can discard the stems and gills or save them for another use like making a vegetable broth. Place the prepared mushroom caps, gill-side up, on a baking sheet.
Creating the Flavorful Filling
Step 2: Sauté the Aromatics
Now, let’s build the base of our flavorful filling. Heat 1 tablespoon of the olive oil in a skillet over medium heat. Once the oil is shimmering, add the finely chopped onion. Sauté the onion for about 3-5 minutes, stirring occasionally, until it becomes softened and translucent. You’re looking for a nice gentle cooking that brings out its natural sweetness without browning it too much. Next, add the minced garlic to the skillet. Cook for another minute until fragrant, being careful not to burn the garlic, as burnt garlic can turn bitter. This aromatic foundation is crucial for infusing the entire stuffing with wonderful flavor.
Step 3: Wilt the Spinach
Once the garlic is fragrant, add the roughly chopped fresh spinach to the skillet. This might seem like a lot of spinach, but it will wilt down significantly. Stir the spinach into the onion and garlic mixture. Continue to cook, stirring occasionally, for about 2-3 minutes, or until the spinach has completely wilted. You want to remove as much excess moisture from the spinach as possible at this stage. If there seems to be a lot of liquid in the pan from the spinach, you can gently drain some of it off by tilting the skillet carefully over the sink. This will help prevent the stuffing from becoming too wet.
Step 4: Combine the Cheeses and Seasonings
Remove the skillet from the heat. Add the ricotta cheese and grated Parmesan cheese to the wilted spinach and onion mixture. Season generously with salt and black pepper. If you’re using nutmeg, add it now – a little goes a long way, and it complements the creamy cheeses beautifully. Stir everything together until all the ingredients are well combined and the cheeses are starting to melt and create a creamy, cohesive filling. Taste the mixture at this point and adjust the seasonings if needed. Remember, the Parmesan cheese will add saltiness, so be mindful of that when adding more salt.
Stuffing and Baking the Mushrooms
Step 5: Stuff and Bake the Portobellos
Now it’s time to assemble our masterpiece. Preheat your oven to 375°F (190°C). Spoon the spinach and cheese filling generously into each of the prepared portobello mushroom caps, mounding it slightly in the center. Make sure to distribute the filling evenly among the four caps. Drizzle the remaining 1 tablespoon of olive oil over the stuffed mushrooms. This will help them cook evenly and develop a lovely texture. Finally, sprinkle the shredded mozzarella cheese over the top of the filling on each mushroom. The mozzarella will melt and become wonderfully gooey and golden brown as it bakes. Place the stuffed portobellos back onto the baking sheet and bake for 20-25 minutes, or until the mushrooms are tender and the cheese is melted and bubbly, with a few golden-brown spots. For an extra touch of flavor and visual appeal, you can sprinkle a little more grated Parmesan cheese over the top just before serving. Let them cool slightly before enjoying these delectable Spinach and Cheese Stuffed Portobello Mushrooms.

Frequently Asked Questions:
Can I make the Spinach and Cheese Stuffed Portobello Mushroom ahead of time?
Yes, you absolutely can! You can prepare the filling and stuff the mushrooms a day in advance. Store them covered in the refrigerator. When you’re ready to bake, simply follow the baking instructions, adding a few extra minutes to account for them being chilled.
