How to Make Roasted Vegetable Tart

1
Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper and set aside.
2
In a large skillet or sauté pan, heat the olive oil over medium-high heat. Add the sliced onions and cook, stirring occasionally, until they are caramelized and golden brown, about 20-25 minutes.
3
Add the minced garlic to the skillet and cook for 1-2 minutes, stirring constantly, until fragrant.
4
Add the sliced mushrooms to the skillet and cook, stirring occasionally, until they are tender and lightly browned, about 10-12 minutes.
5
Add the sliced bell peppers to the skillet and cook, stirring occasionally, until they are tender and lightly browned, about 10-12 minutes.
6
In a large bowl, whisk together the flour and salt. Add the cold butter and use a pastry blender or your fingers to work it into the flour until the mixture resembles coarse crumbs.
7
Gradually add the ice-cold water to the bowl, stirring with a fork until the dough comes together in a ball.
8
Turn the dough out onto a lightly floured surface and roll it out to a thickness of about 1/8 inch. Transfer the dough to a 9-inch tart pan with removable bottom.
9
Arrange the roasted vegetables in the tart shell, leaving a 1-inch border around the edges. Sprinkle the grated Parmesan cheese over the top of the vegetables.
10
Fold the edges of the crust up over the filling, pressing gently to seal. Brush the crust with a little bit of olive oil and sprinkle with chopped fresh parsley.
11
Bake the tart for 25-30 minutes, or until the crust is golden brown and the filling is heated through.
12
Remove the tart from the oven and let it cool for 10-15 minutes before serving. Serve warm, garnished with additional parsley if desired.
