Spinach and Cheese Stuffed Portobello Mushroom Ingredients
For the Stuffing
• Portobello mushrooms – Their hearty caps hold the creamy filling perfectly. Substitute with cremini or white button mushrooms, adjusting cooking time as needed.
• Olive oil – Adds moisture and promotes browning of the mushrooms. You can use avocado oil or melted butter instead.
• Butter – This ingredient enriches the sautéed spinach filling. For a dairy-free option, swap it with vegan butter.
• Garlic powder – A dash enhances the savory profile of the dish. Fresh minced garlic works well as a substitute too.
• Fresh spinach – Offers a nutritious and flavorful element to the stuffing; you can use frozen spinach if thawed and drained thoroughly.
For the Cheesy Mixture
• Ricotta cheese – Provides a rich creaminess to the filling. Cottage cheese, cream cheese, or mascarpone are great alternatives.
• Shredded mozzarella cheese – Melts beautifully, adding that gooey texture we all love. Feel free to substitute with any well-melting cheese like provolone.
• Grated Parmesan cheese – Delivers a salty, nutty flavor that rounds out the taste. Pecorino Romano or a vegan cheese can be good alternate options.
• Crushed red pepper flakes – Infuses a hint of heat, bringing an exciting touch to the dish (optional based on your heat preference).
For Seasoning
• Salt and black pepper – These basics elevate the overall flavor of your stuffing; adjust to taste.
Step‑by‑Step Instructions for Spinach and Cheese Stuffed Portobello Mushroom
Step 1: Preheat the Oven
Begin your culinary journey by preheating your oven to 375°F (190°C). This will ensure that your Spinach and Cheese Stuffed Portobello Mushrooms bake evenly and develop a delightful golden hue. While the oven heats, gather your ingredients and equipment, including a baking sheet lined with parchment paper.
Step 2: Prepare the Mushrooms
Carefully clean the Portobello mushrooms using a damp cloth to remove any dirt. Once clean, gently remove the stems and scrape out the gills with a spoon. This step not only creates space for the flavorful filling but also prevents excess moisture, ensuring a perfect texture in your stuffed mushrooms.
Step 3: Arrange the Mushroom Caps
Place the mushroom caps, stem side up, on the prepared baking sheet. This arrangement allows for the filling to rest securely within each mushroom. Take a moment to admire the earthy shape of the Portobello mushrooms before you season them; they’re the star of this Spinach and Cheese Stuffed Portobello Mushroom recipe!
Step 4: Season the Mushrooms
Drizzle a little olive oil over the tops of the mushroom caps, making sure to coat them evenly. Sprinkle garlic powder, salt, and black pepper to taste. These seasonings will enhance the savory flavors of the mushrooms. Once seasoned, it’s time to bring them to the oven for a quick bake.
Step 5: Bake the Mushrooms
Slide the baking sheet into the preheated oven and bake the mushrooms for 10-12 minutes. You want them to soften slightly but not become soggy. Keep an eye on them until they become tender; this is a crucial step for optimal flavor and texture in your Spinach and Cheese Stuffed Portobello Mushrooms.
Step 6: Sauté the Spinach
While the mushrooms bake, prepare the filling. In a skillet, melt butter over medium heat, then add fresh spinach. Sauté for about 3-4 minutes, stirring until the spinach wilts and reduces. This step transforms the spinach into a flavorful filling that melds beautifully with the cheeses.
Step 7: Prepare the Cheese Mixture
In a bowl, combine ricotta, shredded mozzarella, grated Parmesan, and optional crushed red pepper flakes. Mix until well incorporated. This creamy cheese mixture will be a heavenly complement to the vibrant sautéed spinach, ensuring your Spinach and Cheese Stuffed Portobello Mushrooms are rich and satisfying.
Step 8: Combine the Filling
Once the sautéed spinach has cooled slightly, chop it finely and fold it into the prepared cheese mixture. Mix thoroughly until all ingredients are blended. The combination of spinach and cheese provides a flavorful explosion, creating the perfect filling for your Portobello mushrooms.
Step 9: Stuff the Mushrooms
Fill each baked mushroom cap generously with the creamy spinach and cheese mixture. Pack the filling gently, ensuring it mounds slightly above the rim. This step is vital for achieving that delicious, cheesy top that will emerge from the oven.
Step 10: Bake Again
Return your stuffed mushrooms to the oven and bake for another 10-12 minutes. You’ll know they’re done when the cheese is bubbly and golden brown. As you wait, the aroma wafting through your kitchen will make keeping patience worthwhile!
Step 11: Cool and Serve
After baking, remove the Spinach and Cheese Stuffed Portobello Mushrooms from the oven and allow them to cool slightly. This short rest will help the flavors settle. Serve them warm as an impressive appetizer or a delightful main dish, and watch your guests savor every bite!
