Description
This quiche is one of those back-pocket recipes I keep coming back to when I need something reliable but still a bit special. It’s creamy, cheesy, and packed with simple veg that somehow taste better together than on their own.
Ingredients
- 375 g ready rolled shortcrust pastry
- 1 onion, finely sliced
- 6 mushrooms, sliced
- 1/2 courgette, thinly sliced
- 3 eggs
- 150 ml semi-skimmed milk
- 4 tbsp single cream or whipping cream, or use extra milk
- 100 g extra mature Cheddar cheese, grated
- 1 tsp chives, finely chopped
- Salt and pepper, to taste
- 1 tbsp oil or butter, for sautéing
Instructions
- Preheat your oven to 350⁰F (180⁰C).
- Place a baking sheet in the oven to heat up; it helps the base cook through nicely.
- Unroll the 375 g ready rolled shortcrust pastry over a 20 cm flan tin.
- Gently press it into the edges without stretching it too much. Trim any excess with a knife.
- Line the pastry with baking parchment and fill with baking beans or scrunched foil.
- Bake for 10 minutes, then remove the parchment and beans and bake for another 5 minutes until lightly set. If it puffs a bit, press it down gently with a spoon.
- While that’s baking, heat 1 tbsp oil or butter in a pan.
- Add the 1 finely sliced onion, 6 sliced mushrooms, and ½ courgette, thinly sliced with a pinch of salt and pepper.
- Cook for about 8 to 10 minutes until softened and any liquid has cooked off. Don’t rush this part or the quiche can turn watery.
- In a jug, whisk together the 3 eggs, 150 ml semi-skimmed milk, and 4 tbsp cream (or extra milk) with a good pinch of salt and pepper.
- Sprinkle half of the 100 g grated Cheddar cheese over the base of the pastry.
- Spoon the cooked veg mixture evenly over the cheese, then scatter the remaining cheese on top along with the 1 tsp chopped chives.
- Place the flan tin onto the hot baking sheet in the oven, then carefully pour in the egg mixture. This will prevent spilling when moving the dish to the oven.
- Bake for about 30 minutes until just set in the centre with a slight wobble.
- If it’s browning too quickly, loosely cover with foil for the last 10 minutes.
- Let it sit for at least 10 minutes before slicing.
- It firms up as it rests and slices much cleaner.
