The Charm of Savory Tarts
Tarts have long been a staple in French cuisine, with both sweet and savory versions offering an elegant yet simple way to enjoy a variety of ingredients. The combination of buttery pastry and a rich filling makes for a dish that is satisfying without being too heavy.
A Leek, Mushroom & Thyme Tart embraces the depth of umami-rich mushrooms, the gentle onion-like flavor of leeks, and the aromatic notes of thyme, making it an ideal dish for those who appreciate fresh, seasonal ingredients.
Ingredients for the Perfect Leek, Mushroom & Thyme Tart
For the Pastry:
1 ¼ cups all-purpose flour
½ teaspoon salt
½ cup unsalted butter, cold and cubed
3-4 tablespoons ice water
For the Filling:
2 tablespoons olive oil
1 tablespoon butter
2 large leeks, cleaned and sliced (white and light green parts only)
2 cups mushrooms, sliced (button, cremini, or a mix)
2 cloves garlic, minced
1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme)
Salt and black pepper, to taste
3 large eggs
¾ cup heavy cream or whole milk
½ cup grated Gruyère or Parmesancheese
1 teaspoon Dijon mustard (optional, for extra depth of flavor)
A pinch of nutmeg (optional, for warmth)
How to Make a Leek, Mushroom & Thyme Tart
Step 1: Prepare the Pastry
In a bowl, mix the flour and salt.
Add the cold, cubed butter and use a pastry cutter or your fingers to blend until the mixture resembles coarse crumbs.
Gradually add the ice water, one tablespoon at a time, mixing just until the dough comes together.
Form the dough into a disk, wrap it in plastic wrap, and chill for at least 30 minutes.
Preheat your oven to 375°F (190°C). Roll out the chilled dough on a floured surface and fit it into a 9-inch tart pan. Trim any excess and prick the base with a fork.
Line the crust with parchment paper and fill with pie weights or dried beans. Bake for 12 minutes, then remove the weights and bake for another 5-7 minutes, until lightly golden. Set aside.
Step 2: Prepare the Filling
Heat olive oil and butter in a large skillet over medium heat.
Add the sliced leeks and sauté for 5 minutes, until softened.
Add the mushrooms and cook for another 5-7 minutes, until they release their moisture and become golden.
Stir in the garlic and thyme, and cook for another minute. Season with salt and pepper to taste.
Step 3: Make the Custard Mixture
In a bowl, whisk together the eggs, heavy cream, Dijon mustard, nutmeg (if using), and half of the grated cheese.
Stir the cooked leeks and mushrooms into the egg mixture.
Step 4: Assemble and Bake
Pour the filling into the pre-baked tart crust.
Sprinkle the remaining cheese on top.
Bake at 375°F (190°C) for 25-30 minutes, until the filling is set and the top is lightly golden.
Allow the tart to cool slightly before serving.
