Ingredients & Preparation Notes

- Onion: Finely chop the onion to ensure it melds well with the other ingredients.
- Garlic: Mince the garlic for even distribution of flavor throughout the filling.
- Butter: Use unsalted butter to control the saltiness of the dish. Melt it gently to avoid burning.
- Filo Pastry: Thaw frozen filo in the refrigerator overnight for the best results. Keep it covered with a damp cloth while working to prevent drying out.
- Feta Cheese: Crumble the feta to ensure it distributes evenly in the filling.
- Ricotta Cheese: Adds creaminess to the filling; full-fat or part-skim works well.
- Eggs: Beat the eggs well before adding to the filling to ensure a cohesive mixture.
- Parsley: Fresh parsley adds a burst of freshness; chop finely for even distribution.
- Oregano: Dried oregano adds depth of flavor; use fresh if available, but double the amount.
- Salt and Pepper: Season to taste, keeping in mind the saltiness of the feta cheese.
Professional Tips & Techniques
- Filo Handling: Work quickly with filo pastry to prevent it from drying out. Keep unused sheets covered with a damp cloth.
- Layering: Brush each filo sheet with butter to ensure a crispy, golden crust. Rotate the dish slightly with each layer to cover the bottom and sides evenly.
- Filling Temperature: Let the mushroom and spinach mixture cool slightly before adding to the egg and cheese mixture to prevent the eggs from cooking prematurely.
- Baking Time: Check the pie after 35 minutes; if the top is browning too quickly, cover with foil for the remaining time.
- Doneness: The pie is done when the filo is golden brown and crispy, and the filling is set. Use a knife to check the center for doneness.
Recipe Variations
- Vegan Version: Substitute dairy with vegan cheese alternatives and use a flaxseed or aquafaba egg replacer.
- Meat Lover’s Twist: Add cooked, crumbled sausage or ground beef to the filling for a heartier pie.
- Herb Variations: Experiment with different herbs like dill or thyme for a unique flavor profile.
- Cheese Swaps: Try using goat cheese or a mix of mozzarella and Parmesan for different taste and texture.
- Gluten-Free Option: Use gluten-free filo pastry or substitute with a gluten-free pie crust.
- Seasonal Adaptations: In the fall, add butternut squash or pumpkin to the filling for a seasonal twist.
- Spicy Kick: Add red pepper flakes or diced jalapeños to the filling for a spicier version.
- Mediterranean Flair: Incorporate sun-dried tomatoes and olives for a Mediterranean-inspired pie.

Mushroom and Spinach Filo Pie
Equipment
- Large skillet
- 9-inch pie dish
- Pastry brush
Ingredients
- 1 lb mushrooms sliced
- 10 oz spinach fresh, washed
- 1 medium onion finely chopped
- 2 cloves garlic minced
- 4 tbsp butter melted
- 8 sheets filo pastry thawed if frozen
- 1 cup feta cheese crumbled
- 1/2 cup ricotta cheese
- 2 large eggs beaten
- 1/4 cup fresh parsley chopped
- 1 tsp dried oregano
Instructions
- Preheat your oven to 375°F (190°C). In a large skillet, heat 2 tablespoons of butter over medium heat. Add the onions and cook until softened, about 5 minutes.
- Add the garlic and mushrooms to the skillet. Cook until the mushrooms release their moisture and start to brown, about 10 minutes. Stir in the spinach and cook until wilted, about 3 minutes. Remove from heat and let cool slightly.
- In a large bowl, mix the feta cheese, ricotta cheese, eggs, parsley, oregano, and season with salt and pepper. Add the cooled mushroom and spinach mixture, and stir to combine.
- Brush a 9-inch pie dish with some of the remaining melted butter. Lay one sheet of filo pastry in the dish, letting the edges hang over the sides. Brush with butter. Repeat with 3 more sheets, rotating the dish slightly each time to cover the bottom and sides.
- Pour the filling into the filo-lined dish. Fold the overhanging filo over the filling. Layer the remaining 4 sheets of filo on top, brushing each with butter and rotating the dish slightly.
- Bake in the preheated oven for 45 minutes, or until the filo is golden brown and crispy. Let cool for 10 minutes before slicing and serving.
