Pre-baking the pastry ensures even baking and a golden-brown crust. Allowing the tart to cool slightly after baking allows the flavors to develop and makes it easier to cut into clean slices.

Serving individual slices on slightly warmed plates helps keep the tart pleasant to eat.

To add an extra source of protein and a delicate flavor, you can add salmon. Use about 150g of fresh salmon, cut into small pieces. Stir it into the leeks and mushrooms in the pan towards the end of cooking so it begins to cook slightly before being placed on the pastry. The salmon will continue to cook in the oven, developing a tender texture and a slightly briny flavor that complements the sweetness of the leeks and the richness of the filling.
Leek, mushroom and walnut tart
To add crunch and a slightly sweet flavor, you can incorporate noix Chopped walnuts. You'll need about 50g. Scatter them over the filling just before pouring in the egg and cream mixture, so they stay crunchy after baking.

Leek, mushroom and goat cheese tart
For a more pronounced flavor and creamy texture, add 100g of crumbled goat cheese. Scatter it over the vegetables before pouring in the quiche mixture so it melts gently during baking. This variation adds a touch of acidity and a more intense aroma, which pairs beautifully with the sweetness of the leeks and the umami flavor of the mushrooms.

Benefits of mushroom and leek tart
Fiber intake
The tart provides fiber thanks to the leeks and mushrooms. This can be increased by using semi-wholemeal flour for the pastry. Fiber promotes intestinal transit by facilitating the passage of food through the digestive system. It also contributes to maintaining a healthy gut flora and supports the proper functioning of the digestive system.
Vitamins and minerals
Leeks provide B vitamins, particularly B6, which plays a role in protein metabolism and nervous system function. Mushrooms are rich in vitamin D and selenium, an important trace element for protecting cells against oxidative stress. Adding eggs and cheese provides calcium, phosphorus, and magnesium, essential for maintaining strong bones and proper muscle function.
Proteins and lipids
The eggs and cheese included provide complete proteins, containing all the essential amino acids needed for tissue repair and muscle maintenance. These proteins also play a role in the production of enzymes and hormones, and contribute to a lasting feeling of fullness, as do the fats in the cream.
Antioxidants and bioactive compounds
Leeks contain sulfur compounds and flavonoids, while mushrooms provide polysaccharides and specific antioxidants. These components help protect cells against oxidative damage and support the normal function of the immune system. The presence of vitamin B and minerals enhances these effects by participating in numerous essential metabolic processes.
