Heat a frypan over medium heat and add the oil. Cook the onion and bacon for 8-10 minutes until the bacon is crispy and the onion has caramelised.
Squeeze the excess water out of the spinach and set to the side.
In a medium sized bowl crack in the eggs and pour in the milk or cream. Season with salt and pepper and use a fork to combine the ingredients together.
Add the onion and bacon to the quiche crust along with the spinach and cheese.
Pour over the custard and place into a 180C | 350F oven for about 50 minutes or until the centre only slightly jiggles when moved.
Cool the quiche for 10-15 minutes before serving.
Notes
Cream is best used for this quiche, but half and half or milk can also be used.
