Place onions, unsalted butter, and olive oil in a large covered pan or stockpot. Add whole chicken and enough water so the chicken is nearly submerged.
02 -
Cover and bring to a boil over medium-high heat. Reduce to a gentle simmer and poach the chicken for about 90 minutes, until fully cooked.
03 -
Remove the chicken and set aside to cool. Strain the cooking liquid into another pan, reserving the onions. Rapidly boil the liquid to reduce it to a gelatinous stock.
04 -
Once cool enough to handle, strip all meat from the chicken, discarding the skin and bones.
05 -
In a large bowl, mix the shredded chicken and reserved onions. Add beaten eggs and enough reduced stock to moisten the filling. Season with black pepper and salt to taste.

Preheat the oven to 230°C. Grease a round pie dish with olive oil.

Line the prepared dish with 3 sheets of filo pastry, alternating direction and brushing each layer lightly with olive oil.
08 -
Add the chicken mixture to the lined dish. Fold over any overhanging filo edges. Cover with the remaining 3 sheets of filo, alternating orientation. Fold in edges to seal and brush the top thoroughly with olive oil.
09 -
Bake in the preheated oven for 15 minutes.

Allow the pie to rest for 10 to 20 minutes after baking. Serve warm.
