Cover the bottom of a 24cm pie dish with baking paper, roll out 300g puff pastry, put in the pie dish and use a fork to make small holes
Mince 2 cloves of garlic and 1 shallot, brown them in 2 tbsp butter over low heat,
Then add 300g mixed forest mushrooms, roughly hacked .
Cook the whole over high heat without covering. To avoid a soggy quiche make sure no liquid is left
During this time, preheat your oven to 200°C. Beat 2 eggs in a bowl. Then add 100 ml liquid cream and 20g grated Gruyere. Season with salt and pepper.
Cover the puff pastry bottom with 1 tbsp Dyon mustard, then sprinkle with 60g grated Gruyere. Mustard and cheese will keep the pastry dry, so no need for double baking.
Now spoon your pan-fried forest mix in
Finally pour the egg mix over the mushrooms and sprinkle with more grated cheese.
Bake in the hot oven for 30-40 minutes.
Serve this forest quiche with a green salad or an endive salad.
