For the Galette Crust:

  • 1 and 1/4 cups all-purpose flour
  • 3/4 tsp salt
  • 1 tsp granulated sugar
  • 1/2 cup cold salted butter (1 stick, 8 tbsp, or 113 grams)
  • 1/4 cup full-fat cold sour cream
  • 5 tbsp ice cold water, plus more as needed

For the Roasted Butternut Squash:

  • 2 lbs butternut squash, cubed about 6 cups
  • 2 tbsp olive oil
  • 2 large cloves garlic, minced
  • 1/2 tsp dried thyme
  • 1/2 tsp dried sage
  • 1/2 tsp salt
  • 1/4 tsp` pepper

For the Rest of the Galette:

  • 2/3 cup grated parmesan cheese (the little shreds, not the powdery stuff)
  • 2/3 cup grated asiago cheese
  • 1 egg, for egg washing the crust


  • Make the Pie Dough: In a medium mixing bowl, whisk together the flour, salt, and sugar. Cut the butter into large chunks and add to the dry ingredients. Use a pastry cutter or clean hands to cut the butter into the dry ingredients until you have chunks the size of blueberries (some will be a bit bigger, and some a bit smaller).
    Drizzle in the water and add the sour cream. Toss with a fork until the dough is moistened and the sour cream is mixed in. Gently gather the dough into a ball. If the dough holds when you push it together, it's ready. If it's a bit dry and crumbles apart, add a bit more water, 1 to 2 tablespoons at a time. You can also flick some water onto any dry bits hiding in the bottom of the bowl. Gently flatten the ball of dough a bit, into a 1-inch thick disc. It will be a little scrappy looking but should hold together. Wrap the disc tightly in plastic wrap and chill in the freezer for at leas 1 hour or in the fridge for at least 2 hours. If you freeze the dough for 1 hour, and your filling isn't ready yet, move the dough to the fridge so it doesn't freeze solid.
    Make-Ahead Tip: Dough can be made ahead and refrigerated for 2-3 days before using, or frozen for up to two months. Let it thaw in the fridge overnight before using, if you froze it.

  • Roast the Squash: Pre-heat your oven to 400° F. Add the cubed squash to a large baking sheet in an even layer and toss with the olive oil, minced garlic, thyme, sage, salt, and pepper. Roast for 20-30 minutes, until squash is fork-tender.
  • Roll out the Dough and Assemble the Galette: Preheat the oven to 375° F, and line a large baking sheet with parchment paper or a silicone baking mat. Flour your countertop and rolling pin. Unwrap the dough and sprinkle lightly with flour. Begin rolling out the dough gently, turning continuously so it doesn't stick to the counter. Sprinkle more flour under the dough as needed. Be a little patient here - we're not trying to stretch the dough all the way out in a few passes. Once the dough is about 12 to 14 inches in diameter and about 1/8 inch thick, gently roll it up onto the rolling pin and transfer it onto the prepared baking sheet. Evenly spread the two kinds of cheese on the galette, leaving about 2-3 inches of border. Evenly distribute the roasted squash over the cheese. Fold up the edges of the dough, working in small sections, to cover edges of the squash. Galettes are rustic - don't fuss over this too much.
    Chill the assembled galette, uncovered, in the fridge for 15 minutes to re-chill before baking. Beat the egg in a small bowl. Once the galette has chilled, brush the egg wash over the edges of the crust.
  • Bake: Bake for 48 to 58 minutes, covering with foil at about the 40 minute mark if the top of the squash pieces are starting to brown too much. The crust should be golden brown and should feel and sound crisp when lightly tapped. You can also gently lift the corner of it with a flipper to make sure the crust looks browned underneath.
  • Serve + Store: Serve immediately, with an additional sprinkle of cheese. This is absolutely best when it's fresh from the oven. Leftovers can be stored in an airtight container in the fridge for a few days, and gently re-heated.
  • Make-Ahead Tips: I don't recommend making this galette ahead of time, as the crust will only get less crisp as the days go on. However, you can make the dough ahead of time (see tips above in the dough-making direction), and you can roast the squash ahead of time, cool it, and store it in an airtight container in the fridge for up to 1 day ahead of baking the galette.
