Step‑by‑Step Instructions for Spinach and Cheese Stuffed Portobello Mushroom
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While it’s heating, take two large Portobello mushrooms and gently clean them by wiping with a damp cloth. Carefully remove the stems and use a spoon to scrape out the gills, making space for the flavorful filling. You want the caps to be sturdy and ready to hold all the delicious ingredients.
Step 2: Season the Mushrooms
Place the prepared mushrooms on a lined baking sheet, ensuring they are caps facing up. Drizzle the mushrooms generously with one tablespoon of olive oil and sprinkle with ½ teaspoon garlic powder, ¼ teaspoon salt, and ¼ teaspoon black pepper. Use a brush or your fingers to rub the seasoning evenly across the caps, ensuring each mushroom is well-coated for great flavor before baking.
Step 3: Bake the Mushrooms
Slide the baking sheet into the preheated oven and bake the mushrooms for about 10-12 minutes. You’ll know they’re ready when they become tender and start to release their juices, enhancing their earthy aroma. This step is crucial as it sets the stage for the filling to meld beautifully with the mushrooms.
Step 4: Sauté the Spinach
While the mushrooms are baking, melt one tablespoon of butter in a skillet over medium heat. Add 2 cups of fresh spinach to the skillet and sauté for about 3-4 minutes until the spinach is wilted and vibrant. Keep stirring to avoid burning, then remove the skillet from heat and let the sautéed spinach cool slightly before handling it.
Step 5: Mix the Filling
Once the spinach has cooled, use a kitchen towel to thoroughly dry it, squeezing out any excess moisture to prevent a watery filling. Finely chop the spinach and combine it in a bowl with ½ cup ricotta cheese, ½ cup shredded mozzarella cheese, ¼ cup grated Parmesan cheese, and ¼ teaspoon crushed red pepper flakes. Stir until all the ingredients are well mixed, forming a creamy, cohesive filling.
Step 6: Stuff the Mushrooms
After the mushrooms have baked and cooled a bit, take the filling mixture and generously stuff each mushroom cap, making sure to pack it in tightly for maximum flavor. Use a spoon to mound the filling and create a visually appealing presentation. The Spinach and Cheese Stuffed Portobello Mushrooms are now ready for their final baking!
Step 7: Final Bake
Return the stuffed mushrooms to the oven and bake for an additional 10-12 minutes. During this time, you’ll see the cheese bubbling and the tops getting a lovely golden color, signifying that the filling is warm and the flavors have melded beautifully.
Step 8: Cool and Serve
Once baked, carefully remove the mushrooms from the oven and allow them to cool for a few minutes. This brief cooling period helps the flavors deepen and makes them easier to handle. Serve warm as a delightful main dish or a charming appetizer, and revel in the delicious aroma of your Spinach and Cheese Stuffed Portobello Mushrooms!
