Ingredients Equipment Method Notes

Ingredients
  

  • 1 pre-made or homemade 9-inch pie crust preferably butter-based
  • 3 large leeks white and light green parts, cleaned thoroughly
  • 1 tbsp butter for caramelizing leeks
  • 1 cup sharp cheddar cheese preferably aged, grated
  • 3 large eggs at room temperature
  • 200 ml heavy cream at room temperature
  • 1 tsp salt to taste
  • 1/2 tsp black pepper freshly ground
  • a pinch nutmeg optional, freshly grated
  • a few sprigs fresh thyme for flavor

Equipment

  • 9-inch tart pan with removable bottom
  • Rolling pin
  • Parchment paper and pie weights
  • Sauté pan
  • Mixing bowl
  • Whisk
  • Oven

Method
 

  1. Preheat your oven to 180°C (350°F). Roll out your pie crust on a lightly floured surface and fit it into a 9-inch tart pan, gently pressing into the edges. Prick the bottom with a fork, then line with parchment paper and fill with pie weights or dried beans. Bake for 15 minutes, then remove the weights and parchment and bake for another 5 minutes until lightly golden.
  2. While the crust bakes, prepare the leeks. Trim the dark green tops and roots, then slice the white and light green parts thinly. Rinse thoroughly under cold water, tossing to remove dirt trapped between layers, then drain well.
  3. In a sauté pan, melt the butter over medium-low heat. Add the sliced leeks and a pinch of salt, then cook slowly, stirring occasionally. Let them soften and caramelize gently for about 15-20 minutes until they turn a deep golden brown and smell sweet and toasted.
  4. In a mixing bowl, whisk together the eggs, heavy cream, salt, pepper, and nutmeg if using, until smooth and slightly frothy. Stir in the grated cheddar cheese.
  5. Once the leeks are caramelized and slightly cooled, spread them evenly over the prebaked crust. Pour the custard mixture over the leeks, filling the tart shell to the top and smoothing the surface gently.
  6. Bake the quiche in the oven for 25-30 minutes, until the filling is just set with a slight jiggle in the center and the top turns a light golden. The crust should be crisp and fully baked.
  7. Remove the quiche from the oven and let it rest for about 10 minutes. This allows the filling to set further and makes slicing easier.
  8. Slice the quiche with a sharp knife, serve warm or at room temperature, garnished with a sprig of thyme or a sprinkle of cheese. Enjoy the rich flavors and smooth texture of this elegant, comforting dish.

Notes

For an extra layer of flavor, sprinkle some additional cheese on top before baking. To make the crust extra flaky, chill the dough before rolling. This quiche pairs beautifully with a simple green salad.
