120 g (1 cup) all-purpose flour
30 g (~1/4 cup) parmesan cheese, finely grated
1/2 tsp kosher salt
1/2 tsp black pepper
140 g (10 tbsp) unsalted butter, cold
90 ml (6 tbsp) ice water
Caramelized Onions:
2 tbsp olive oil
4 medium yellow onions
Kosher salt, to taste
2 cloves garlic, thinly sliced
Squash, Sweet Potato, and Red Onion Petals:
1/2 butternut squash
1/2 acorn squash
1 medium sweet potato
Kosher salt, to taste
57 g (1/4 cup) unsalted butter, melted
Flaky salt, for finishing
Assembly:
2 tbsp white miso
2 tbsp warm water
2 tbsp olive oil
Kosher salt, to taste
57 g (1/4 cup) unsalted butter, melted
Instructions
- Make the Shortcrust: Preheat oven to 350°F. Line a 10-inch tart pan with parchment. Mix flours, parmesan, salt, and pepper. Grate in cold butter and rub until crumbly. Add ice water until dough comes together. Form into a disc, wrap, and chill 1 hour.
- Caramelize the Onions: Thinly slice onions. Cook in olive oil with salt over medium heat until golden (15 minutes). Add garlic and cook 20–30 minutes more until deeply caramelized. Set aside.
- Prepare Vegetables: Thinly slice butternut squash, acorn squash, sweet potato, and red onion into uniform slices.
- Assemble: Roll chilled dough to 1/8-inch thick and line tart pan. Freeze 15 minutes. Mix miso with warm water and brush over crust. Spread caramelized onions evenly. Arrange sliced vegetables in concentric circles. Drizzle with olive oil, season, and brush lightly with melted butter.
- Bake: Bake at 350°F for 75–85 minutes until vegetables are tender and crust is golden. Cool slightly, sprinkle with flaky salt, and serve warm or at room temperature.
Notes
- Add crumbled goat cheese or feta for extra creaminess.
- Use kabocha squash for a sweeter variation.
- Infuse caramelized onions with thyme or rosemary for added flavor.
- Swap parmesan with pecorino for a sharper taste.
- Brush vegetables with maple butter for a sweet-savory twist.
