Don't be scared by the name--a galette (pronounced with a hard 'g') is a simple rustic tart that can have either a sweet or savory filling. This recipe makes a terrific main dish, and it is perfect for fall. Serves 6.
For the pastry:
1 1/4 cups flour (up to 1/4 cup can be whole wheat)
1/4 teaspoon salt
8 tablespoons (1 stick) butter
1/4 cup sour cream
2 teaspoons lemon juice
1/4 cup ice water
For the filling:
1 small butternut squash (about one pound)
2 tablespoons olive oil
2 tablespoons butter
1 large onion, halved and thinly sliced in half-moons
1 teaspoon salt
Pinch of sugar
1/4 teaspoon cayenne, or to taste
1/2 cup shredded mozzarella cheese
1/4 cup shredded Parmesan cheese
1 1/2 teaspoons chopped fresh sage (or 1/4 teaspoon dried)
1. Make pastry: In a bowl, combine the flour and salt. Add the butter, and using a pastry blender cut it in until the mixture resembles coarse meal. In a small bowl, whisk together the sour cream, lemon juice and water and add half of this mixture to the flour-butter mixture. With your fingertips, mix in the liquid until large lumps form. Remove the large lumps and repeat with the remaining liquid and flour-butter mixture. Pat the lumps into a ball; do not overwork the dough. Cover with plastic wrap and refrigerate for 1 hour.
2. Prepare squash: Preheat oven to 375 degrees F. Peel squash, then halve and scoop out seeds. Cut into a 1/2-inch dice. Toss pieces with olive oil and a half-teaspoon of the salt and roast on baking sheet for 30 minutes or until pieces are tender. Set aside to cool slightly.
3. Caramelize onions: While squash is roasting, melt butter in a heavy skillet and cook onion over low heat with the remaining half-teaspoon of salt and pinch of sugar, stirring occasionally, until soft and lightly golden brown, about 20 minutes. Stir in cayenne.
4. Raise the oven temperature to 400 degrees. Mix squash, caramelized onions, cheeses and herbs together in a bowl.
5. Assemble galette: On a floured work surface, roll the dough out into a 12-inch round. Transfer to an ungreased baking sheet. Spread the squash mixture over the dough, leaving a 1 1/2-inch border. Fold the border over the filling, pleating the edge to make it fit. The center will be open.
6. Bake until golden brown, 30 to 40 minutes. Remove from the oven, let stand for 5 minutes before serving.
