Ingredients

crust [makes 2 large galette crusts. keep one in the freezer!]

  • 4 cups sifted all-purpose flour
  • 1 tablespoon sugar
  • 3 teaspoons salt
  • 1/2 teaspoon dried oregano
  • 1/2 teaspoond dried basil
  • 1/4 teaspoon dried sage
  • 1 large egg, lightly beaten
  • 1 teaspoon white vinegar
  • 1/2 cup ice cold water
  • 1 1/2 cups cold unsalted butter, cut into pieces (3 sticks or 24 tablespoons)
  • for brushing: 1 egg + a few drops of water, beaten together

filling

  • 2 shallots, thinly sliced
  • tablespoons unsalted butter
  • 1/4 teaspoon salt
  • 1 teaspoon brown sugar
  • 2 sweet potatoes, peeled and sliced thinly on a mandolin
  • 6 ounces goat cheese, crumbled

pepita gremolata

  • 1 tablespoon roasted pepitas
  • 1 1/2 tablespoons olive oil
  • 1 teaspoon fresh lemon juice
  • 2 tablespoons chopped flat leaf parsley
  • 2 teaspoons chopped fresh basil
  • 1 garlic clove, minced

Instructions 

crust

  • Add the flour, sugar, herbs and salt to a food processor and pulse just until combined. In a small bowl, whisk mix together the egg, vinegar and water. Add the cold butter pieces into the food processor and pulse until small coarse crumbs remain. Sprinkle the water/egg mixture over the flour and pulse again until the dough comes together.
  • Remove the dough with your hands and wrap it in plastic wrap. This dough makes enough for 2 galette crusts, so you can either separate it into 2 sections now, or separate it after it’s refrigerated. Refrigerate the dough for 30 minutes.
  • After 30 minutes, preheat the oven to 400 degrees F.

filling

  • Heat the butter in a skillet over low heat. Once melted, stir in the shallots with the salt. Cook on low heat, stirring occasionally, until the shallots are caramely in color, about 35 to 45 minutes. Stir in the brown sugar and cook for 10 more minutes. Remove from the heat and set aside. You can do this while the crust is chilling in the fridge!
  • Slice the sweet potatoes into paper thin rounds using a mandolin. You can truly have as many sweet potatoes as you want in the galette!
  • Remove one of the crusts from the fridge. (The other is good for another week or so, or it can be frozen.) Roll one of the pie crusts into a… “rustic” shape – no shape necessary really – until it is about 1/4 inch thick. Place the dough on a parchment-lined baking sheet. Add the sweet potatoes in the center, alternating layers between sweet potato rounds, caramelized shallots and crumbled goat cheese, leaving a 2-inch+ border of crust. I also like to sprinkle the layers of sweet potato with salt and pepper as I go. Once the filling is added, fold the crust over top of the squash. Brush the crust with the beaten egg wash. Bake the galette until the crust is golden, about 45 to 50 minutes.
  • Remove and let cool slightly before brushing it with the gremolata and serving.

pepita gremolata

  • Add the pepitas to a food processor and pulse until crushed. Add in the remaining ingredients and pulse until combined. Brush over the galette.
