3 medium-sized potatoes (about 600g, peeled and thinly sliced)
2 medium leeks (about 200g, cleaned and finely sliced (white part only))
2 tablespoons unsalted butter
1 tablespoon olive oil
2 cloves garlic (minced)
1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme)
Salt (to taste)
freshly ground black pepper (to taste)
1 cup heavy cream (240ml)
2 large eggs
1 teaspoon Dijon mustard
½ cup grated Gruyère cheese (optional, for extra flavor)
Fresh thyme sprigs (for garnish, optional)
Extra grated cheese (for garnish, optional)
Instructions
Preheat your oven to 200°C. This is important for the puff pastry to rise and become crispy.
Roll out the puff pastry on a baking sheet lined with parchment paper, ensuring it is evenly spread and the edges slightly overhang.
In a pan over medium heat, melt the butter and olive oil. Add the finely sliced leeks and sauté for about 5 minutes until soft and lightly golden.
Add the minced garlic and fresh thyme leaves, and sauté for another 2 minutes until fragrant.
In a large bowl, combine the thinly sliced potatoes with the leek mixture. Season with salt and pepper to enhance the flavor.
In a separate bowl, whisk together the cream, eggs, and Dijon mustard.
Spread the potato-leek mixture evenly over the puff pastry. Pour the cream mixture over the filling and optionally sprinkle the grated Gruyère cheese on top.
Fold the edges of the puff pastry carefully over the filling, leaving a small gap in the center for steam to escape.
Bake the tart in the preheated oven for 30-35 minutes until the puff pastry is golden brown and the filling is set.
Remove the tart from the oven and let it cool for about 10 minutes before slicing and serving.
