# Components:
→ Pastry
01 - 2 cups all-purpose flour
02 - 1/2 cup cold unsalted butter, cubed
03 - 1 egg yolk
04 - 2 to 3 tablespoons cold water
05 - 1/2 teaspoon salt
→ Filling
06 - 1 medium sweet potato, peeled and diced
07 - 1 small butternut squash, peeled and diced
08 - 2 tablespoons olive oil
09 - 1 large red onion, thinly sliced
10 - 2 tablespoons unsalted butter
11 - 2 tablespoons pure maple syrup
12 - 3.5 ounces goat cheese, crumbled
13 - 2 eggs
14 - 2/3 cup crème fraîche
15 - 1 teaspoon fresh thyme leaves
16 - Salt and freshly ground black pepper, to taste
# Method:
01 - Set oven to 400°F (200°C) to begin preparations.
02 - In a large bowl, combine flour and salt. Cut in cold butter until mixture resembles coarse crumbs. Add egg yolk and just enough cold water to form a dough. Shape into a disk, wrap in plastic wrap, and refrigerate for 20 minutes.
03 - Toss diced sweet potato and butternut squash with olive oil, salt, and pepper. Spread on a baking sheet and roast for 20–25 minutes until golden and tender. Reduce oven temperature to 350°F (180°C).
04 - Melt butter in a skillet over medium heat. Add thinly sliced red onion and cook until soft and caramelized, approximately 10–12 minutes. Stir in maple syrup and cook for an additional 2 minutes. Remove from heat.
05 - Roll out chilled dough on a lightly floured surface and fit into a 9-inch tart pan. Prick the base with a fork and blind-bake in the oven for 10 minutes.
06 - In a bowl, whisk together eggs, crème fraîche, fresh thyme, salt, and pepper until well combined.
07 - Layer the roasted vegetables and caramelized onions evenly inside the blind-baked pastry shell. Sprinkle crumbled goat cheese over the top, then pour the custard mixture evenly over the filling.
08 - Bake in the preheated oven at 350°F (180°C) for 25–30 minutes, or until the custard is set and the top is lightly golden.
09 - Allow the tart to cool slightly before removing from the pan. Optionally, shape extra pastry using a maple leaf cutter, bake until golden, and garnish the tart before serving.
