How to Make Leek Tart with Gruyere and Onions
Prepare the Dough: In your food processor, combine the flour and salt. Add the cold butter and pulse until the mix resembles small crumbs. Gradually add the chilled water until the dough forms, ensuring it remains cool.
Roll and Chill: Transfer the dough onto lightly floured baking paper, forming a disk. Cover with another sheet of baking paper, roll it out into a large rectangle, and chill in the fridge for at least 1 hour to firm up.
Line the Pan: Once chilled, peel off the baking paper and line your baking pan with the shortcrust pastry. Poke small holes with a fork to prevent bubbling. Chill the lined pan in the fridge for 30 minutes, then freeze for 15 minutes before baking.
Preheat and Blind Bake: Preheat your oven to 180°C (350°F). Blind bake the pastry for about 10 to 15 minutes, or until lightly golden. Remove it from the oven and let it cool.
Sauté the Vegetables: Clean and chop the leeks into thin slices, and slice the onion. In a non-stick pan, melt the butter over medium heat and sauté the leeks, onion, and minced garlic for about 5 minutes until the onions are translucent. Allow to cool slightly.
Mix the Filling: In a separate bowl, whisk the eggs with cream, salt, pepper, and cumin. Stir in the sautéed leeks and onions, followed by the grated Gruyere cheese for that creamy finish.
Optional: Garnish with fresh herbs like thyme for an added pop of flavor!

Avoid Gritty Leeks: Thoroughly wash your leeks before slicing. They often hide dirt and grit in their layers, which can spoil your delicious tart.
