Ingredients

• Large Cremini Mushrooms (18-24): These sturdy mushrooms provide the perfect vessel for our savory filling. Cremini mushrooms, also known as baby bellas, offer a deeper, more earthy flavor than white button mushrooms, which holds up beautifully to baking and stuffing. Choose mushrooms that are firm, plump, and uniform in size for even cooking and an appealing presentation.
• Fresh Spinach (5 ounces): The star of our filling, fresh spinach brings a vibrant green color and a delicate earthy sweetness. Spinach is packed with nutrients and adds a healthy element to this appetizer. Make sure to thoroughly wash and dry the spinach to remove any grit and excess moisture before using.
• Feta Cheese (4 ounces): Crumbled feta cheese provides a salty, tangy, and creamy counterpoint to the earthy mushrooms and spinach. Feta cheese is traditionally made from sheep’s milk or a blend of sheep’s and goat’s milk, giving it a distinctive flavor and texture. Look for a block of feta in brine for the best flavor and moisture, and crumble it yourself for optimal texture.
• Shallot (1 medium): Finely diced shallot adds a subtle onion-like flavor that is milder and slightly sweeter than yellow onion, perfect for a delicate stuffing. Shallots belong to the allium family and have a more refined taste that complements the other ingredients without overpowering them.
• Garlic (2 cloves): Minced garlic is essential for adding aromatic depth and savory notes to the filling. Fresh garlic cloves offer a much more pungent and flavorful experience compared to pre-minced garlic. Mince the garlic finely to ensure it distributes evenly throughout the stuffing and cooks through completely.
• Breadcrumbs (1/2 cup): Plain breadcrumbs, either panko or regular, act as a binder and add a pleasant textural element to the stuffing. Breadcrumbs absorb excess moisture from the spinach and cheese, helping the filling hold its shape and preventing it from becoming too wet. Panko breadcrumbs will provide a lighter, crispier texture, while regular breadcrumbs will create a denser, more cohesive filling.
• Olive Oil (3 tablespoons): Olive oil is used for sautéing the shallot and garlic, as well as for brushing the mushrooms before baking. Olive oil adds richness and flavor while also preventing the mushrooms from drying out in the oven. Choose a good quality extra virgin olive oil for the best flavor and health benefits.
• Dried Oregano (1 teaspoon): Dried oregano adds a warm, slightly peppery, and aromatic Mediterranean flavor that pairs perfectly with spinach and feta. Oregano is a staple herb in Greek and Italian cuisine and brings a classic touch to this dish.
• Dried Thyme (1/2 teaspoon): Dried thyme contributes a subtle earthy, slightly minty, and lemony flavor that complements the oregano and enhances the overall herbaceousness of the filling. Thyme is another classic Mediterranean herb that adds depth and complexity to the flavor profile.
• Red Pepper Flakes (1/4 teaspoon, optional): Red pepper flakes provide a subtle kick of heat that balances the richness of the cheese and adds a layer of complexity. If you prefer a milder flavor, you can omit the red pepper flakes or reduce the amount.
• Salt and Black Pepper: Salt and freshly ground black pepper are essential for seasoning and enhancing the flavors of all the ingredients. Season generously to taste, adjusting as needed throughout the cooking process.
• Fresh Parsley (2 tablespoons, chopped, for garnish): Freshly chopped parsley adds a bright, fresh, and herbaceous garnish that not only enhances the visual appeal of the dish but also adds a final touch of flavor. Parsley provides a clean, slightly peppery note that complements the richness of the stuffed mushrooms.

Instructions

1. Prepare the Mushrooms: Begin by gently cleaning the mushrooms. Use a damp paper towel or a soft mushroom brush to wipe away any dirt or debris from the mushroom caps. Avoid soaking the mushrooms in water, as they are porous and will absorb moisture, which can make them soggy. Carefully remove the stems from each mushroom cap by gently twisting and pulling them out. Set the mushroom caps aside and finely chop the mushroom stems. Don’t discard the stems! They will be used in our delicious filling, adding extra mushroom flavor and texture.
2. Sauté Aromatics and Mushroom Stems: Heat 2 tablespoons of olive oil in a large skillet over medium heat. Once the oil is shimmering, add the finely diced shallot and cook for about 3-4 minutes, or until softened and translucent. Stir occasionally to prevent burning. Add the minced garlic and chopped mushroom stems to the skillet and cook for another 2-3 minutes, until the garlic is fragrant and the mushroom stems have softened slightly. Cooking the shallot, garlic, and mushroom stems at this stage is crucial for developing depth of flavor in the filling.
3. Wilt the Spinach: Add the fresh spinach to the skillet with the shallot, garlic, and mushroom stems. You might need to add the spinach in batches, as it will wilt down significantly. Cook, stirring frequently, until the spinach is completely wilted and has reduced in volume. This should only take a few minutes. Once the spinach is wilted, continue to cook for another minute or two to evaporate any excess moisture released from the spinach. Excess moisture in the filling can make the stuffed mushrooms soggy.
4. Combine Filling Ingredients: Remove the skillet from the heat. In a large bowl, combine the wilted spinach mixture, crumbled feta cheese, breadcrumbs, dried oregano, dried thyme, and red pepper flakes (if using). Season generously with salt and freshly ground black pepper. Remember that feta cheese is already salty, so taste the filling before adding too much salt. Mix all the ingredients together thoroughly until well combined. The breadcrumbs will help to absorb any remaining moisture and bind the filling together.
5. Preheat Oven and Prepare Baking Sheet: Preheat your oven to 375°F (190°C). Lightly grease a baking sheet or line it with parchment paper for easy cleanup. Parchment paper will also prevent the mushrooms from sticking to the baking sheet.
6. Stuff the Mushroom Caps: Brush the mushroom caps, both inside and out, with the remaining 1 tablespoon of olive oil. This will help to prevent them from drying out during baking and add a touch of richness. Spoon the spinach and feta filling generously into each mushroom cap, mounding it slightly. Don’t be afraid to pack the filling in, as it will shrink slightly during baking.
7. Bake the Stuffed Mushrooms: Arrange the stuffed mushroom caps on the prepared baking sheet. Bake in the preheated oven for 20-25 minutes, or until the mushrooms are tender and the filling is heated through and lightly golden brown on top. The baking time may vary slightly depending on the size of your mushrooms and your oven. Keep an eye on them and check for tenderness with a fork.
8. Garnish and Serve: Once baked, remove the stuffed mushrooms from the oven and let them cool slightly for a few minutes. Garnish with freshly chopped parsley before serving. The parsley adds a fresh, vibrant touch and enhances the overall flavor and presentation. Serve the Spinach & Feta Stuffed Mushrooms warm as an appetizer, side dish, or vegetarian main course.

Additional Tips for Perfect Spinach & Feta Stuffed Mushrooms

1. Choose the Right Mushrooms: Opt for large cremini or baby bella mushrooms for stuffing. Their size and sturdy texture make them ideal for holding the filling. White button mushrooms can also be used, but they are smaller and have a milder flavor. Portobello mushrooms can be used for larger, main-course sized stuffed mushrooms, but will require longer baking time.
2. Don’t Overcrowd the Pan When Sautéing: Sauté the shallots, garlic, and mushroom stems in a single layer in the skillet. Overcrowding the pan will cause the vegetables to steam instead of sautéing, resulting in less flavorful and potentially soggy filling. If necessary, sauté in batches.
3. Squeeze Out Excess Moisture from Spinach: After wilting the spinach, make sure to squeeze out as much excess moisture as possible. Too much moisture in the filling can make the stuffed mushrooms soggy and prevent them from browning properly. You can do this by placing the wilted spinach in a clean kitchen towel or cheesecloth and squeezing firmly.
4. Customize the Cheese: While feta is classic, you can experiment with other cheeses. Try using goat cheese for a tangier flavor, ricotta cheese for a creamier texture, or a blend of mozzarella and Parmesan for a more Italian-inspired taste. Blue cheese crumbles can also add a bold and pungent flavor.
5. Add Protein to the Filling: For a heartier and more protein-rich stuffing, consider adding cooked ingredients like crumbled Italian sausage, ground beef, or cooked quinoa or lentils. These additions will make the stuffed mushrooms more substantial and suitable as a main course.
6. Spice it Up: Adjust the spice level to your liking. Increase the amount of red pepper flakes for more heat, or add a pinch of cayenne pepper or a dash of hot sauce. You can also incorporate other spices like smoked paprika, cumin, or coriander for different flavor profiles.
7. Make Ahead and Bake Later: You can prepare the stuffed mushrooms ahead of time and bake them later. Assemble the stuffed mushrooms and store them, covered, in the refrigerator for up to 4 hours before baking. This makes them a great option for entertaining as you can get ahead on the preparation. Add a few extra minutes to the baking time if baking directly from the refrigerator.
8. Freeze for Future Enjoyment: Baked stuffed mushrooms can be frozen for future enjoyment. Allow the baked mushrooms to cool completely, then arrange them in a single layer on a baking sheet and freeze until solid. Once frozen, transfer them to a freezer-safe bag or container. To reheat, bake from frozen at 350°F (175°C) for 20-25 minutes, or until heated through.

Frequently Asked Questions (FAQ)

Q1: Can I use frozen spinach instead of fresh spinach?
A: Yes, you can use frozen spinach, but make sure to thaw it completely and squeeze out as much excess moisture as possible before using. Frozen spinach tends to retain more water than fresh spinach, so thorough draining is crucial to prevent a soggy filling. You’ll need about half the weight of frozen spinach compared to fresh.

Q2: I don’t have shallots, can I use onions instead?
A: Yes, you can substitute shallots with yellow or white onion. Use about half of a small yellow or white onion, finely diced, in place of the shallot. Onions have a stronger flavor than shallots, so using a smaller amount will prevent them from overpowering the other flavors in the filling.

Q3: Can I make these stuffed mushrooms vegan?
A: To make these stuffed mushrooms vegan, you can substitute the feta cheese with a vegan feta alternative or nutritional yeast for a cheesy flavor. Ensure your breadcrumbs are also vegan-friendly. There are many delicious vegan feta cheeses available now made from tofu, nuts, or coconut oil that would work well in this recipe.

Q4: How long do stuffed mushrooms last in the refrigerator?
A: Cooked Spinach & Feta Stuffed Mushrooms can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat them in the oven or microwave until heated through before serving. Ensure they are cooled completely before refrigerating to prevent condensation.

Q5: Can I grill these stuffed mushrooms instead of baking them?
A: Yes, you can grill stuffed mushrooms. Preheat your grill to medium heat. Place the stuffed mushrooms on a grill pan or a piece of foil to prevent them from falling through the grates. Grill for 15-20 minutes, or until the mushrooms are tender and the filling is heated through and lightly browned. Grilling will impart a smoky flavor to the mushrooms.

Q6: What other herbs can I add to the filling?
A: Feel free to experiment with other herbs in the filling. Fresh herbs like dill, mint, or basil would complement the spinach and feta beautifully. You could also try adding a pinch of dried rosemary or marjoram for a different flavor profile. Fresh herbs are best added at the end of cooking to preserve their flavor and aroma.

Q7: Can I add a topping to the stuffed mushrooms?
A: Yes, you can add a topping to the stuffed mushrooms for extra flavor and texture. Consider topping them with grated Parmesan cheese, breadcrumbs mixed with melted butter, or a drizzle of balsamic glaze before baking or after they come out of the oven. A sprinkle of toasted pine nuts or chopped walnuts would also add a nice crunch.

Q8: My stuffed mushrooms are releasing a lot of liquid while baking, what should I do?
A: Mushrooms naturally release liquid when cooked. To minimize this, you can pre-bake the mushroom caps for about 5-10 minutes before stuffing them to release some of their moisture. Also, ensure you have squeezed out excess moisture from the spinach and that your filling isn’t too wet. If they are releasing liquid while baking, you can carefully drain some of the liquid from the baking sheet halfway through baking to prevent them from becoming soggy.
