Roasted Apple and Butternut Galette

Preheat oven to 425 degrees F.

Place prepared squash, apples, and onion onto a rimmed cookie sheet. Toss with the oil, then spread them out in a single layer. Roast in the center of the oven until everything is tender and beginning to turn golden (and even darker) in spots, about 35-40 minutes. Remove from the oven and let it cool until room temperature. TIP: You can do this a day ahead of time. Simply store the roasted bits in the fridge, covered, until ready to use.

Preheat (or reduce temperature) to 375 degrees F.

Whisk together the maple syrup and the mustard in a small bowl. Set aside.

Roll out pie crust dough into a circle, roughly 12 inches across. Transfer to a clean, rimmed baking sheet. Spread the roasted vegetables onto the dough circle evenly, leaving a 2-inch border all around. Brush the maple-mustard mixture onto the vegetables. Fold the dough edges toward the center, sealing any cracks or rips. You should have a rustic-looking free-form pie.

Bake in the center of the oven for about 25 minutes, until the crust is golden brown. Let it sit for 10 minutes or so before slicing. (It stays together better that way). Cut into slices and sprinkle some Parmesan shavings over top.

Serves 4.

Notes:
1. You could also use frozen butternut squash chunks if you like. I would thaw them first and drain any excess moisture before roasting.
2. You could also whisk an egg and brush it around the edges of the pie crust. That helps it to brown more beautifully.
