# Components:
→ Pastry
01 - 2 cups all-purpose flour
02 - 9 tablespoons 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 pepper, to taste
# Directions:
01 - Set the oven to 400°F (200°C) to prepare for roasting vegetables.
02 - In a large bowl, combine flour and salt. Add cold butter and rub in until mixture resembles coarse crumbs. Incorporate egg yolk and add just enough cold water to bring dough together. Shape into a disk, wrap in plastic, and chill for 20 minutes.
03 - Toss diced sweet potato and butternut squash with olive oil, salt, and pepper. Spread on baking sheet and roast for 20–25 minutes until tender and golden. Reduce oven temperature to 350°F (180°C).
04 - Melt butter in a skillet over medium heat. Add sliced red onion and cook for 10–12 minutes until soft and caramelized. Stir in maple syrup, cook for 2 additional minutes, then set aside.
05 - Roll out chilled dough on a lightly floured surface and line a 9-inch tart pan. Prick base with a fork and bake without filling for 10 minutes.
06 - Whisk together eggs, crème fraîche, fresh thyme, salt, and pepper until smooth.
07 - Layer roasted vegetables and caramelized onions evenly in tart shell. Sprinkle crumbled goat cheese over the top. Pour custard mixture evenly over the filling.
08 - Bake at 350°F (180°C) for 25–30 minutes until filling is set and top is lightly golden.
09 - Allow tart to cool slightly before removing from pan. Optionally, decorate with baked pastry cutouts shaped like maple leaves.
