Sourdough Galette with Delicata Squash

This galette is a bit of a project if you start from zero at seven in the evening. Pre-make most of the components when you have a few minutes here or there in the days prior, and it will come together effortlessly.

Ingredients

Green Chile Yogurt

  • 2 garlic cloves, peeled
  • 150 g Greek Yogurt
  • 2 tablespoons minced jalapeño or serrano chile, or to taste

Walnut Pâte Brisée

  • 45 g walnuts
  • 30 g rye flour
  • 80 g unbleached all-purpose flour
  • 10 g granulated sugar
  • 1/2 teaspoon fine grain sea salt
  • 75 g unsalted butter, chilled
  • 50 g 100% hydration sourdough starter*
  • 20 g gin, vodka, or ice water

Toppings

  • 2 medium delicata squash
  • 2 medium shallots, peeled and thinly sliced
  • extra virgin olive oil
  • 4 ounces / 115g mozzarella
  • salt, to taste
  • 1 bunch scallions, thinly sliced with greens
  • 1 egg yolk

Instructions

  1. To make the green chile yogurt, chop the garlic into a paste, transfer to a small bowl and combine with the yogurt and minced chiles. Set aside. Keep in mind you can make this, and refrigerate, a day or two in advance.

Prepare the crust dough:

  1. The same goes for the Walnut Pâte Brisée crust, I usually make it a day or two in advance. Combine the walnuts, flours, sugar, and salt in a food processor. Pulse until the walnuts are ground fine. Cut the chilled butter into little cubes and add to the processor. Pulse until the mixture is like cornmeal with tiny pebbles. Add the starter and the gin, vodka, or ice water, and pulse until everything comes together. Transfer the dough onto a lightly floured surface, and knead once or twice until the dough comes together. Shape into a round disk, roughly an inch-thick, wrap in plastic, and refrigerate for at least 30 minutes.

Pre-roast toppings:

  1. Heat the oven to 400F. Slice the delicata squash in half lengthwise, clean out the seeds (wash and toast those as well!), and then slice the delicata into 1/4-inch thick crescent moon shapes (see photo). Toss with a generous splash of olive oil and the sliced shallots, sprinkle with a bit of salt, and arrange on a baking sheet. Bake until the squash starts to take on some color - 20 - 25 minutes. Allow to cool.

To assemble the galette:

  1. Remove the dough from the refrigerator and allow to soften for 5-10 minutes. Roll out on a lightly floured countertop (or parchment paper) until 1/4-inch thick. Transfer to a baking sheet. Spread the yogurt mixture across the galette to within an inch of the edge. Layer with the pre-roasted delicata squash and shallots, tear the mozzarella into pieces and add that as well. Finish with most of the scallions. Fold the crust edges in toward the center about an inch or so, working clockwise (see photo). Whisk the egg yolk with 2 tablespoons of water and brush the crust. Bake for 30-35 minutes or until the crust is beautifully golden.

  2. Remove from the oven, and finish with toasted seeds and remaining scallions.
