How To Make Mary Berry Cheese and Onion Quiche
A step-by-step guide to this classic vegetarian dish.
- Make the Pastry: Tip the flour into a large bowl. Add the cold, cubed butter and rub it in with your fingertips until the mixture resembles fine breadcrumbs. Add the cold water and bring the dough together into a ball.
- Line and Chill the Tin: On a lightly floured surface, roll out the pastry and use it to line a 20cm (8in) loose-bottomed flan tin. Press the pastry into the sides, trim the excess, and prick the base with a fork. Chill in the refrigerator for 30 minutes.
- Blind Bake the Crust: Preheat the oven to 220°C (200°C Fan/Gas Mark 7). Line the chilled pastry case with baking parchment, fill with baking beans, and bake for 15 minutes. Remove the beans and paper and bake for another 5 minutes until the base is lightly golden.
- Cook the Filling: While the pastry bakes, reduce the oven temperature to 180°C (160°C Fan/Gas Mark 4). In a frying pan, melt the butter and gently cook the chopped onions for about 20 minutes, until very soft and lightly golden, but not browned.
- Assemble the Quiche: Spoon the softened onions into the bottom of the baked pastry case. Sprinkle the grated Cheddar cheese over the top of the onions.
- Add Custard and Bake: In a jug, whisk together the eggs, single cream, and milk. Season well with salt and pepper. Carefully pour this custard mixture into the quiche. Bake for 25–30 minutes, until the filling is golden and just set with a very slight wobble in the center.

Recipe Tips
For a perfect, creamy quiche with a crisp crust every time.
- How do I prevent a soggy bottom? “Blind baking” the pastry case before adding the wet filling is Mary Berry’s secret to a perfectly crisp crust. This initial bake cooks and seals the pastry, preventing the custard from making it soggy.
- How to get the sweetest onions? The key is to cook them low and slow. Don’t rush this step. Gently cooking the onions in butter for a full 20 minutes allows their natural sugars to release, making them sweet and tender, which is the perfect flavor base for the quiche.
- How do I know when the quiche is done? The key is to not overcook it. The quiche is perfectly baked when the edges are set, but the very center still has a slight jiggle or wobble when you gently shake the tin. It will continue to set as it cools.
- Can I use a different cheese? Yes. While a strong, mature Cheddar provides a classic, tangy flavor, this quiche would also be delicious with other hard cheeses like Red Leicester, Gruyère, or a mix of Cheddar and Parmesan.
What To Serve With Cheese and Onion Quiche

How To Store Cheese and Onion Quiche
Keeping your delicious quiche fresh.
- Refrigerate: Once completely cooled, cover the quiche with plastic wrap or foil and store it in the refrigerator for up to 3 days.

FAQs
While homemade pastry is highly recommended for the best flavor and texture, you can absolutely use a store-bought, ready-made shortcrust pastry case or a sheet of ready-to-roll pastry as a convenient shortcut.
A watery or split custard is often the result of overcooking, which causes the eggs to curdle. It can also happen if the onions are not cooked down enough and release their water into the custard during baking. Make sure the onions are very soft before adding them to the case.
Of course. This is a great base recipe. You could add sautéed leeks instead of onions, or add other ingredients like chopped, cooked mushrooms or some fresh herbs like chives or thyme to the filling before adding the custard.
