Instructions

Step 1: Sift the flour and a pinch of salt into a large bowl. Add the cold, diced butter and rub it into the flour using your fingertips until the mixture resembles breadcrumbs.

Step 2: Stir in the icing sugar, egg yolk, and 3 tablespoons of cold water. Quickly bring the mixture together to form a firm dough. Wrap the dough tightly in cling film and refrigerate for 20 minutes to rest.

Step 3: Preheat the oven to 200°C (180°C fan/gas mark 6). Roll out the rested pastry on a lightly floured surface to fit a deep 23cm tart tin. Line the tin with the pastry, then cover with baking parchment and fill with baking beans.

Step 4: Bake the lined pastry case for 20 minutes. Remove the baking parchment and beans, then bake for an additional 5-10 minutes until the pastry is pale and sandy in texture.

Step 5: Reduce the oven temperature to 160°C (140°C fan/gas mark 2). Layer the cooked new potatoes, sliced spring onions, and diced Montgomery cheddar evenly in the tart case.

Step 6: In a bowl, whisk together the eggs, milk, and double cream. Season with salt and pepper to taste. Pour this custard mixture over the layered ingredients in the tart case.

Step 7: Bake the quiche for 40-45 minutes, until the filling is just set and slightly golden on top. Remove from the oven and allow to cool on a wire rack before serving.

Tips & Variations

For extra flavor, try adding fresh herbs like thyme or chives to the egg mixture before baking.

Use Yukon Gold or other waxy potatoes if new potatoes aren’t available; just be sure to cook them until tender before adding.

If Montgomery cheddar is hard to find, a sharp mature cheddar makes a good substitute with a similar tangy flavor.

Blind baking the pastry ensures a crisp crust that won’t become soggy from the creamy filling.

FAQs

Can I prepare the pastry and filling ahead of time?

Yes, you can prepare the pastry dough and blind bake the crust a day in advance. Store the baked pastry case in the fridge, well wrapped, until ready to fill and bake.

Is it possible to make this quiche vegetarian?

This recipe is already vegetarian as it contains no meat. For a vegan version, you would need to replace the eggs, cream, and cheddar with vegan alternatives, but the texture and flavor will change significantly.
