You might think that making a quiche is complicated, but it’s actually so easy, even a complete beginner in the kitchen can nail it.

There are countless quiche fillings to choose from, and you can use as many or as little ingredients you like.

What is a quiche?

Quiche is a French baked savoury tart consisting in a pastry crust with an egg and milk and/or cream filling.

The filling can be either vegetarian, using pretty much any kind of veggies, or you can have it with either chicken, bacon, seafood, ham, you name it.

Quiche can be served either hot or cold, and it makes the perfect appetizer for every occasion.

It’s also a great packed lunch idea; so if you are looking for a work lunch, or even a healthy bite for your little one’s school lunch box, this is the recipe you need.

Forget about unnecessary expenses, you can make a restaurant-style quiche yourself with only a few ingredients. Just use anything you have in your fridge, and you’ll get a fantastic quiche every single time.

How do you make asparagus, mushroom and leek quiche?

Whether you make a quiche or any sort of pie, the filling MUST ALWAYS BE COOL, to make sure the steam coming from it does not make the crust soggy.

So, start with the filling, in this way you can get the crust done while the filling is cooling down.

How do you make the mushroom and leek filling?

  • sautee the chopped mushrooms and leek until tender, and the liquid released is completely evaporated

It might look at first that there’s too much leek and mushrooms for one quiche, but keep in mind that once they are cooked, you are left with perhaps quarter on the amount that went into the pan.

Mushrooms and leeks have a high amount of water, once it’s released, you’ll have just enough for your filling.

  • season well with salt and pepper, then remove from the heat and leave to cool

How do you keep a quiche crust from getting soggy?

A good quiche starts with a good crust. No need to buy ready-made crusts that have hundreds of dodgy ingredients, a quiche crust only needs two ingredients:

  • flour
  • butter

And one-two tablespoons of cold water, in case the dough does not come together. Now, once the dough is ready, refrigerate it for at least 30 minutes before you roll it out.

The answer is simple: BLIND BAKING. That means that we pre-bake the crust without the filling. This is particularly important when the filling is wet, and the crust does not have enough time to cook properly, resulting in a soggy bottom.

Since the crust is made of butter, it can shrink considerably in the oven, so we need to cover it with kitchen foil and fill it with either pulses or ceramic balls. 

In this way the crust will be baked to perfection every single time. This process can be used with any kind of pie, savoury or sweet. Bake it for 10-15 minutes, then remove the foil and pulses, and bake for a further 5 minutes.

Once the crust is cooked, add the mushroom and leek filling, the egg and cream mixture, and arrange the asparagus on top. No need to cook the asparagus, it can be raw, since it is going to cook in the oven.

Bake for about 20 minutes until the filling is set and the top is golden.

And that’s it!

  3. Season with salt and pepper, and set aside.

  4. To make the crust, cut the cold butter into cubes, add it to the flour, and use your fingers to rub the butter with the flour until it resembles breadcrumbs.

  5. Add the cold water, and bring together into a dough.

  6. Refrigerate it for at least 30 minutes.

  7. Transfer the dough to the work surface, and use a rolling pin to roll in into about 1/4 cm thickness.

  8. Spread it over a quiche/tart dish, making sure the edges of the dish are covered by dough too, not just the bottom.

  9. Cover the crust with kitchen foil, then fill it with any pulses you have around: lentils, rice, etc If you have baking ceramic balls, even better.

  10. Bake in the pre-heated oven at 180 degrees Celsius (360 Fahrenheit) for 15 minutes, then remove the foil and pulses, and bake for a further 5 minutes until cooked through.

  11. Beat the eggs with a pinch of salt, add the milk and cream and whisk well to combine.
