- 1-1/4 cups all-purpose flour

- 4 cloves garlic, minced
- 1/4 cup chopped mixed herbs, such as parsley, thyme, and rosemary
- 1/2 cup sour cream

To make pastry:
- In a large bowl, whisk together the flour, salt, and pepper.
- Using a cheese grater, shred the frozen butter into the bowl, and toss with the dry ingredients.
- Gently stir in ice-cold water until the mixture is evenly moistened.
- Turn the mixture out onto a floured work surface, and knead gently just until the dough comes together.
- Pat dough into a disk, wrap in plastic wrap, and refrigerate for 1 hour.
To make filling:
- Preheat oven to 425 degrees Fahrenheit.
- In a large bowl, toss the squash and onion with the olive oil, garlic, and herbs.
- Spread the mixture onto a large, rimmed baking sheet.
- Season with additional salt and pepper, as desired.
- Roast for about 20 minutes, or until the squash is tender but not mushy.
- Remove and set aside to cool.
- Increase oven temperature to 450 degrees Fahrenheit.
To assemble galette:
- On a floured surface, roll the dough out to a 14-inch circle.
- Transfer to a baking sheet lined with parchment paper.
- Spread the sour cream over the dough, leaving a 1- to 1-1/2-inch border.
- Top with 1/4 cup cheese.
- Arrange squash-onion mixture over the top, and sprinkle with the remaining cheese.
- Fold the pastry edges up and over the filling, creating a 1- to 1-1/2-inch border.
- Bake for 30 to 35 minutes, or until the crust is nicely browned.
- Cool slightly before slicing and serving.
