- Grease a quiche dish and set aside.
- Place the flour, butter, egg, milk and salt in a bowl and combine into pastry as quickly as possible either with a pastry beater or your hands.
- Once the dough is formed, shape into a ball and cover and refrigerate for 30 minutes.
- Meanwhile, place the olive oil in a medium skillet on medium high heat and add all the onions, cooking until browned and soft, approximately 10 minutes. Stirring every 2-3 minutes to ensure they cook evenly.
- Once well cooked through, remove from the heat and set aside to cool.
- Preheat the oven to 180°C/350F.
- Roll the pastry out and press evenly into your quiche dish, trimming off the excess dough from the edges and shaping to your preference.
- Spoon the onions into the pastry and sprinkle salt evenly over the top.
- Place the eggs and milk into a bowl and whisk lightly to combine, pour evenly and consistently over the top of the onions then sprinkle over the grated cheese.
- Bake for 40 minutes until golden on top and bubbling.
- Remove and allow to cool for 5 minutes.
- Slice and serve.
Make your pastry ahead: The pastry can be made a few days ahead and stored in the fridge.
Precook your onions: The onion can also be cooked in advance and kept covered in the fridge, however, you will want this to be room temperature when adding as a filling.
Add herbs: Some dried or fresh rosemary or thyme would make a great compliment to the sweet onion.
