Preheat the oven to 200°C. Line a baking sheet with parchment paper.

In a large bowl, toss the butternut squash cubes with olive oil, salt, pepper, and thyme. Arrange in a single layer on the prepared baking sheet. Roast for 25–30 minutes, stirring once halfway, until tender and golden.

While the squash roasts, roll out the pie crust or galette dough on a lightly floured surface into a 30 cm circle, approximately 3 mm thick. Transfer to a parchment-lined baking sheet.
04 -
Gently sauté chopped onions or shallots with a splash of olive oil in a skillet over medium heat until soft and translucent, about 5–7 minutes. Remove from heat and set aside.

Once the butternut squash is roasted, let it cool slightly. Scatter sautéed onions over the dough, leaving a 5 cm border. Evenly distribute roasted squash atop the onions, then sprinkle with crumbled goat cheese and grated Parmesan.

Carefully fold the edges of the dough over the filling, pleating to form a rustic border. Brush the exposed dough with beaten egg for a golden finish.

Transfer the galette to the oven and bake for 25–30 minutes, until the crust is golden and crisp.

Cool the galette slightly. Optionally, drizzle with honey. Garnish with fresh parsley or arugula if desired. Slice and serve warm or at room temperature, pairing with a green salad if preferred.
