As Deb at Smitten Kitchen encouraged her readers to make this, I'll do the same. This galette isn't something you should pass up because it might look a little intimidating - believe me, it's easier than any single or double-crusted pie you'll ever make. And the results are just phenomenal. The crust in one word: absolute perfection. It's flakey, buttery, and light...and the filling is all that I expected it to be soft, sweet, savory, with a little bit of a bite from the gruyere that I used rather than the fontina the recipe calls for. I'll make this again and again, and am considering making it this weekend for my girls-night-in dinner party.
I did follow the directions as they were written: freezing the flour mixture and butter for an hour first then preparing the dough by hand and refrigerating it for another hour. While at first glance, this seems a little time consuming, there's not a whole lot of actual preparation going on, and the refrigeration time gave me plenty of time to roast the squash, caramelize the onions, and do a few dishes. ;) Overall, the recipe was quite simple but result was extraordinary!
Butternut Squash and Caramelized Onion Galette
For the pastry:
- 1¼ cups all-purpose flour
- ¼ teaspoon salt
- 8 tablespoons (1 stick) unsalted butter, cut intopieces
- ¼ cup sour cream
- 2 teaspoons fresh lemon juice
- ¼ cup ice water
For the filling:
- 1 small butternut squash (about one pound)
- 2 tablespoons olive oil
- 1 to 2 tablespoons butter (if you have only non-stick, the smaller amount will do)
- 1 large onion, halved and thinly sliced in half-moons
- 1 teaspoon salt
- Pinch of sugar
- ¼ teaspoon cayenne, or to taste
- ¾ cup fontina cheese (about 2½ ounces), grated or cut into small bits (I used gruyere)
- 1½ teaspoons chopped fresh sage leaves
- Make pastry: In a bowl, combine the flour and salt. Place the butter in another bowl. Place both bowls in the freezer for 1 hour. Remove the bowls from the freezer and make a well in the center of the flour. Add the butter to the well and, using a pastry blender, cut it in until the mixture resembles coarse meal. Make another well in the center. In a small bowl, whisk together the sour cream, lemon juice and water and add half of this mixture to the well. 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.
- Prepare squash: Preheat oven to 375 degrees F. Peel squash, then halve and scoop out seeds. Cut into a ½-inch dice. Toss pieces with olive oil and a half-teaspoon of the salt and roast on foil lined (for neatness sake) sheet for 30 minutes or until pieces are tender, turning it midway if your oven bakes unevenly. Set aside to cool slightly.
- 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. (This took more like 30 minutes on low to medium-low heat) Stir in cayenne.
- Raise the oven temperature to 400 degrees. Mix squash, caramelized onions, cheese and herbs together in a bowl.
- Assemble galette: On a floured work surface, roll the dough out into a 12-inch round. Transfer to an ungreased baking sheet. (I used a piece of parchment paper on the sheet) Spread squash, onions, cheese and herb mixture over the dough, leaving a 1 1/2-inch border. Fold the border over the squash, onion and cheese mixture, pleating the edge to make it fit. The center will be open.
- Bake until golden brown, 30 to 40 minutes. Remove from the oven, let stand for 5 minutes, then slide the galette onto a serving plate. Cut into wedges and serve hot, warm or at room temperature. Serves 6.
