Instructions

Working time approx. 50 minutes; Rest time approx. 20 minutes; Cooking/baking time approx. 35 minutes; Total time approx. 1 hour 45 minutes

For the dough, wash the potatoes thoroughly and bring to a boil over high heat, covered, in a pot with enough water to cover the potatoes. Reduce the heat and cook the potatoes until soft. Drain, peel, and allow the steam to evaporate. While warm, press the potatoes through a potato ricer into a large bowl and knead with the yeast, flour, 1 egg, 1 tbsp butter, 1/2 tsp salt, and a little freshly grated nutmeg. Cover and let rise for 20 minutes. For the topping, clean the leek, score it lengthwise, rinse thoroughly under cold running water, and cut into rings. Peel the onions and slice them. Clean the mushrooms and halve or quarter them, depending on their size. Rinse the parsley, shake dry, and chop the leaves. Rinse and halve the tomatoes. Preheat the oven to 180°C (fan). Heat 1 tbsp butter in a pan and sauté the mushrooms over medium heat, then remove. Add the leek rings and onion wedges to the frying fat, cover, and sauté for about 5 minutes. Season with salt and freshly ground pepper. Dust a work surface with a little flour and roll out the dough. Place in a quiche dish greased with a little butter. Prick the dough several times with a fork and bake in the preheated oven for about 10 minutes. Mix the cream cheese with the eggs, parsley, and milk. Season with a little salt and a few turns of freshly ground pepper. Arrange the leek, mushrooms, and tomatoes on the dough. Pour the cream cheese sauce over the dough and bake in the preheated oven for about 25 to 30 minutes.
