For the Shortcrust Pastry:
- 250g (about 2 cups) plain flour, plus extra for dusting
- 125g (about 1/2 cup) cold unsalted butter, cut into cubes
- 1 medium egg, beaten
- 1-2 tbsp cold water
For the Cheese and Onion Filling:
- 25g (about 2 tbsp) butter
- 1 tbsp vegetable oil
- 3 large onions, halved and thinly sliced
- 3 medium eggs
- 150ml (about 2/3 cup) double cream
- 150ml (about 2/3 cup) full-fat milk
- 175g (about 1 3/4 cups) mature Cheddar cheese, grated
- 1 tsp Dijon mustard (optional)
- Salt and freshly ground black pepper

How To Make Hairy Bikers Cheese And Onion Quiche
- Make the pastry: Rub cold butter into the flour until it resembles fine breadcrumbs. Stir in the beaten egg and 1 tablespoon of water until the dough begins to form. Add the second tablespoon if needed. Shape into a ball, wrap in cling film, and chill for 30 minutes.
- Line the quiche tin: Preheat oven to 200°C (180°C Fan) / 400°F / Gas Mark 6. Roll out the pastry and line a 23cm (9-inch) loose-bottomed quiche or flan tin. Press gently and trim excess. Prick the base with a fork.
- Blind bake the pastry: Line with parchment and fill with baking beans or dried rice. Bake for 15 minutes.
- Finish the blind bake: Remove the paper and beans, return pastry to oven for 5–10 minutes until dry and lightly golden. Set aside.
- Cook the onions: Melt butter and oil in a frying pan over low heat. Cook onions gently for 20–25 minutes until soft, sweet, and lightly caramelised.
- Prepare the custard: Whisk together eggs, cream, milk, and Dijon mustard (if using). Season with salt and plenty of black pepper.
- Assemble the quiche: Spread the onions evenly over the pastry base. Sprinkle two-thirds of the grated cheese over the onions.
- Bake the quiche: Pour the egg and cream mixture over the cheese and onions. Sprinkle remaining cheese on top. Bake for 25–30 minutes until golden and just set, with a slight wobble in the center.
- Cool before serving: Let quiche stand for 10–15 minutes in the tin before removing. Serve warm or at room temperature.

Recipe Tips
- How to prevent soggy pastry: Blind bake the pastry fully before adding the filling.
- How to get sweet, caramelised onions: Cook slowly on low heat for 20–25 minutes without rushing.
- Can I make this ahead?: Yes, the quiche can be made a few hours in advance and reheated gently.
- How to get a creamy custard: Do not overbake; a slight wobble in the center ensures a soft set.
- Can I add herbs?: Fresh thyme or chives work well with cheese and onions.
