Difficulty Level

Medium – perfect for home cooks ready to hone their baking and layering skills.

Ingredients

• For the Tart Crust:
• 1 ¼ cups (160g) all-purpose flour, sifted
• ½ cup (115g) unsalted butter, chilled and cubed
• 1 tsp fine sea salt
• 2-3 tbsp ice water
• For the Filling:
• 3 cups mixed mushrooms (cremini, shiitake, oyster), cleaned and sliced
• 2 large leeks, white and light green parts only, thinly sliced
• 2 tbsp extra virgin olive oil
• 2 tbsp unsalted butter
• 2 cloves garlic, minced
• 1 tsp fresh thyme leaves, finely chopped
• ½ tsp fresh rosemary, finely chopped
• ¼ cup Parmesan cheese, grated
• ¼ cup Gruyère cheese, grated
• Salt and fresh ground black pepper, to taste
• 1 large manual egg wash (1 egg beaten with 1 tbsp water)

Instructions

1. Prepare the flaky tart crust: In a large bowl, combine the sifted flour and salt. Add chilled cubed butter and, using a pastry cutter or fingertips, rub until the mixture resembles coarse crumbs with some pea-sized bits.
2. Add ice water: Gradually sprinkle ice water one tablespoon at a time, gently mixing with a fork until the dough just comes together. Avoid overworking to preserve flakiness.
3. Chill the dough: Shape dough into a flat disc, wrap in plastic wrap, and refrigerate for at least 30 minutes.
4. Sauté the leeks and mushrooms: Heat olive oil and butter in a large skillet over medium heat. Add sliced leeks and cook gently for 5 minutes until soft and fragrant.
5. Add mushrooms and garlic: Stir in the mushrooms and garlic, sautéing for another 7-8 minutes until mushrooms release their moisture and begin to brown.
6. Season and add herbs: Mix in thyme and rosemary, seasoning with salt and pepper to taste. Remove from heat and let cool.
7. Preheat the oven: Set oven to 375°F (190°C).
8. Roll out tart dough: On a floured surface, roll chilled dough into a 12-inch circle about ⅛ inch thick. Transfer carefully to a 9-10 inch tart pan with a removable bottom. Press dough into edges and trim excess.
9. Blind bake crust: Line crust with parchment paper and fill with pie weights or dried beans. Bake for 15 minutes, remove weights and paper, then bake 5 more minutes until crust is just beginning to turn golden. Brush edge with egg wash.
10. Layer cheese and filling: Sprinkle the Parmesan and half of the Gruyère evenly into the crust. Spoon the mushroom-leek mixture over the cheese, distributing evenly, then top with remaining Gruyère.
11. Apply egg wash: Lightly brush exposed crust edges with egg wash for enhanced golden crispiness.
12. Bake the tart: Bake for 20-25 minutes until cheese is melted and bubbling, and crust is deeply golden and crisp.
13. Cool and serve: Allow tart to cool for 10 minutes before slicing. This resting ensures the filling sets beautifully for clean slices.

Tips for Success: Mastering Layers of Savory Goodness

• Choosing fresh and firm mushrooms with varied textures elevates each bite-cremini adds earthiness, shiitake brings umami depth, and oyster mushrooms contribute softness.
• Leeks must be cleaned thoroughly to remove grit; slice, then soak in cold water and rinse several times.
• Do not rush the crust chilling process; it’s key for flaky layers, so resist adding extra water or over-kneading.
• For sharpness, substitute Gruyère with aged Manchego or a nutty Asiago cheese.
• Make-ahead tip: The crust and sautéed filling can be prepared a day in advance. Store dough covered in fridge and filling in an airtight container-assemble and bake on serving day for optimal freshness.

Serving Suggestions

Serve slices warm with a simple mixed green salad dressed in lemon vinaigrette for brightness that complements the richness of the tart. Garnish with a few sprigs of fresh thyme or finely chopped chives for a pop of color and herbal aroma. For an indulgent touch, drizzle a small amount of truffle oil over the tart just before serving.
