How to Make Easy Cheese and Onion Quiche

1. Prepare the Pastry: In a mixing bowl, combine flour, butter, and salt. Rub the mixture between your fingers until it resembles breadcrumbs; this creates a light, flaky dough.
2. Add Water Gradually: Slowly add cold water, mixing until a shaggy dough forms. Don t overdo it; you want it to come together without being sticky. Cover and chill in the fridge for 30 minutes.
3. Preheat the Oven: Set your oven to 200 °C (400 °F). This ensures a good rise and browning for your pastry while it bakes.
4. Line and Blind-Bake: Roll out the chilled pastry and line a baking dish. Cover it with parchment paper and fill with baking beans. Bake for 15 minutes, then remove the beans and bake for an additional 5 minutes until lightly golden.
5. Caramelize the Onions: In a skillet, combine butter and sunflower oil over low heat. Add the sliced onions and cook, stirring occasionally for 10-15 minutes until they are softened and beautifully caramelized.
6. Mix the Custard: In a bowl, whisk together eggs and cream cheese. Then gently fold in milk, cream, mustard, paprika, and black pepper until well combined; this will be the creamy filling.
7. Assemble the Quiche: Spread the caramelized onions over the baked pastry. Sprinkle half of the grated cheese, pour over the custard mixture, and finish with the remaining cheese.
8. Bake to Perfection: Lower the oven temperature to 180 °C (360 °F) and bake for 20 minutes, or until the quiche is set and its top is golden brown.

Optional: Serve with a light salad for a refreshing contrast.
