The Ultimate Crowd-Pleasing Appetizer

Looking for the perfect vegetarian appetizer that’s guaranteed to disappear from the plate in minutes? You’ve found it! These Greek-inspired stuffed mushrooms are an absolute flavor explosion. The earthy, umami-rich mushroom caps provide the perfect vessel for a savory, tangy filling of crumbled feta, crunchy walnuts, and aromatic fresh dill. Each bite is a delightful mix of textures that will transport you straight to a sun-drenched Greek island. They’re elegant enough for a dinner party but simple enough for a weeknight treat!

Ingredients

• SERVES 4
• 1/2 cup / 60g walnuts, finely chopped
• 1/2 cup / 60g bread crumbs, plain or panko
• 1 heaping tablespoon fresh dill, finely chopped
• 3/4 cup / 115g feta cheese, finely crumbled
• 2 tablespoons / 30ml milk
• Freshly ground black pepper, to taste
• 16 large cremini or white button mushrooms
• 2 1/2 tablespoons / 37ml olive oil
• Butter, for greasing the baking dish

Instructions

1. Preheat your oven to 375°F / 190°C. In a medium bowl, combine the finely chopped walnuts, bread crumbs, fresh dill, crumbled feta, and milk. Season generously with freshly ground black pepper and mix until everything is well combined.
2. Gently clean the mushrooms with a damp paper towel. Carefully snap off the stems. You can reserve the stems for another use (like a soup stock or pasta sauce) or finely chop them and add them to your filling mixture for extra flavor.
3. Divide the feta and walnut mixture evenly among the mushroom caps, pressing it in firmly to create a generous mound on each one.
4. Generously butter a baking dish large enough to hold the mushrooms in a single layer. Arrange the stuffed mushrooms in the dish and then drizzle the olive oil evenly over the tops.
5. Bake for 20 minutes, or until the mushrooms are tender and juicy and the filling is golden brown on top. Serve immediately and enjoy!

Pro Tips

• Pro-Tips for Perfect Stuffed Mushrooms
• Don’t Wash Your ‘Shrooms: Mushrooms act like sponges and will absorb water, making them soggy. For the best texture, simply wipe them clean with a damp cloth or paper towel.
• Choose the Right Size: Look for cremini (baby bella) mushrooms that are relatively uniform in size and have a deep cap, which makes them easier to fill.
• Make-Ahead Magic: You can assemble these mushrooms up to 24 hours in advance. Just stuff them, place them in the baking dish, cover, and refrigerate. Drizzle with oil just before baking.
• Don’t Waste the Stems: Finely chop the mushroom stems and sauté them for a few minutes before adding them to the filling mixture. This adds a deeper, earthier flavor and reduces waste.

FAQ

Q: Can I make these stuffed mushrooms vegan
A: Yes, you can easily adapt this recipe to be vegan. Replace the feta cheese with a quality vegan feta crumble and use an unsweetened plant-based milk like almond or soy milk. Be sure to grease the baking dish with vegan butter or additional olive oil.

Q: What is a good nut-free substitute for the walnuts
A: For a delicious nut-free version, you can substitute the walnuts with an equal amount of toasted sunflower seeds or pumpkin seeds (pepitas). They will provide a similar savory flavor and satisfying crunch.

Q: How do I store and reheat leftover stuffed mushrooms
A: Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat and maintain the best texture, place them on a baking sheet in an oven at 350°F / 175°C for 10-15 minutes until warmed through.

Q: How can I add more protein to this vegetarian recipe
A: To boost the protein, consider adding finely chopped and sautéed mushroom stems to the filling, as suggested in the Pro-Tips. You could also mix in 1/4 cup of cooked quinoa or crumbled firm tofu for an extra protein punch.
