Butternut Squash, Caramelized Onion and Mushroom Galette

Use your favorite crust recipe if you have one, but I liked the nuttiness of the rye flour from this recipe adapted from Kim Boyce’s elegant Good to the Grain. The dough comes together much like pie crust; I used my food processor which is described in the recipe. To un-veganize it, just use butter. It would also be good with a little Fontina or feta cheese. (Vegan, Vegetarian, Dairy-Free)

Rustic Rye Dough

Ingredients:

1 cup rye flour
3/4 cup unbleached all-purpose flour
2 teaspoons sugar
1 teaspoon kosher salt
4 ounces (1 stick | ½ cup) vegan margarine such as Earth Balance, cold
1 teaspoon apple cider vinegar

Directions:

1.) Sift together dry ingredients. Add to food processor bowl.

2.) Cut butter into ½ inch pieces and add to dry ingredients. Pulse to combine, about 15 seconds. Butter should be slightly broken up but need not be uniform.

3.) Add vinegar. Add 6 tablespoons of ice water and pulse to combine. Pinch a piece of dough between your fingers; if it’s crumbly, add more ice water, one tablespoon at a time.

4.) When the dough stays together when pinched, scrape it onto a piece of plastic wrap, sprinkle a few drops of ice water on top, and wrap it tightly. Refrigerate for at least an hour, or overnight.

5.) After the dough has chilled, turn it out onto a floured surface. Shape it into a square and roll it into a rectangle about 8×11 inches. It’s ok that the dough is ragged, it will come together.

6.) Fold the dough in thirds like a letter. Rotate the dough so that the seam is farthest away from you. Roll the dough out into a 8×11-inch rectangle again and fold it a second time. Rotate, roll, and fold a third time, then wrap the dough in plastic wrap and refrigerate for an hour, or up to 3 days before baking.

Filling:

Ingredients:

1 small butternut squash, approximately 1 pound
1 medium yellow onion, sliced into half moons
12 ounces fresh mushrooms, sliced (I used cremini and oyster)
2 tablespoons olive oil, divided
1 teaspoon kosher or coarse sea salt, divided
1 teaspoon rubbed sage, or 1 tablespoon fresh minced sage leaves
Optional: ¼ cup dry white wine

Directions:

1.) Preheat oven to 375F. Peel the butternut squash, cut it in half length-wise, and scoop out the seeds. Dice the squash and place in a shallow baking dish. Drizzle with a teaspoon or so of olive oil and stir to coat. Bake at 375 for 20 minutes or until tender.

2.) While the squash bakes, heat 1 tablespoon of olive oil over medium heat and add onion slices. Add ¼ teaspoon salt. Stir to coat. Cook, stirring occasionally, about 30 minutes. Add about ¼ cup of water to deglaze the pan.

3.) Heat the remaining 2 teaspoons of oil in a skillet and add the sliced mushrooms. Cook over medium heat, stirring occasionally, about 15 minutes until mushrooms are amber. Add ¼ cup of wine, if using, and stir until reduced.

4.) Combine squash, onions, and mushrooms. Sprinkle with sage and ¾ teaspoon of salt, mix well.

5.) At this point you can refrigerate the fillings, or you can assemble and bake the galette.

Assemble and bake:

1.) Preheat oven to 400F. Line a large baking sheet with parchment paper or a silicone baking mat.

2.) Unwrap chilled dough on a floured work surface. Roll into a circle about 14 inches across, turning frequently. Use a bench scraper to transfer the dough to the prepared baking sheet.

3.) Pour filling into the center of the dough and spread out about 9 inches across. Fold extra dough over the edge, pleating roughly. It doesn’t have to be elegant – it’s supposed to be rustic and homey.

4.) Bake galette at 400F for 30-40 minutes until crust is golden brown. Slice and serve hot, warm, or at room temperature.
