Homemade Spanakopita (Greek Spinach Pie) is an easy and traditional recipe that's so simple to make with fresh flavorful ingredients and flaky filo dough.
Preheat the oven to 350°F (180°C). In a large skillet over medium heat. Heat 2 tablespoons of olive oil, and sautee the yellow onion until soft (3 minutes).
In the same pan, in batches add and wilt the spinach with a little olive oil or a splash of water. Once wilted, remove from the skillet and thoroughly squeeze out excess moisture.
Layer half of the filo pastry, brushing each with olive oil before adding the next. Cover the filo pastry with a damp towel until you use it all up so it does not dry out.
If using, brush the top with egg wash and sprinkle with sesame seeds. Bake for 45 minutes, or until the pastry is golden and crisp. Allow to cool slightly before serving.
