Tarte à l’oignon fondante de grand-mère chaude ou froide et pâte maison effet feuilleté 🧅

An old-fashioned tart with melted onions, just like my grandmother used to make! I'll also show you my homemade savory "flaky" pastry, ultra-simple and delicious – perfect for this recipe. Serve hot or cold, as a starter with a salad, or even as a light main course. 🧅 Ingredients for the homemade pastry: – 200 g flour – 75 ml cold water – 100 g cold butter, cut into pieces – 1 pinch of fleur de sel – 1 teaspoon of herbes de Provence 🥣 For the filling: – 5 to 6 white or yellow onions – 2 tbsp. wholegrain mustard – 100 ml cream (vegetable or not) – 1 egg – Salt, pepper 🔥 Cooking time: 40 minutes at 180°C 💡 Gourmet tip: Add a little grated cheese, tuna, or sliced hard-boiled eggs for a change! ➡️ Let me know in the comments if you prefer it hot... or cold 😋 #oniontart #regionalrecipe #easyrecipe #familycooking #homemade #savorytart Hervé Cuisine is the first cooking tutorial website launched in France in 2007.
