Preparation Steps
1
First, prepare the shortcrust pastry if you're using a homemade version. Roll out the dough and place it into a pie dish. Once the pastry is in place, refrigerate it for 10-15 minutes to prevent it from shrinking during baking.
2
Thinly slice the onions. Heat the oil in a skillet over medium heat, then add the onions. While cooking, add a tablespoon of sugar to help them caramelize. Cook the onions over medium heat for 10-15 minutes, until they are beautifully golden brown and caramelized.
3
In a bowl, crack the eggs and add the heavy cream and milk. Season with salt and pepper, then whisk well to combine.
4
Stir the grated cheese into the egg mixture. Once the onions are ready, fold the caramelized onions into the mixture as well.
5
Pour the prepared mixture onto the pastry base, spreading it evenly. Place in a preheated oven at 350°F (180°C) and bake for approximately 30-35 minutes, or until the top is golden brown and set.
6
Let the quiche cool slightly before slicing and serving.
