Caramelized Onion and Squash Galette: A Rustic Fall Tart

Compiled by the editorial desk with reference to the original recipe and personal narrative from the author's blog.

For those who crave the flavors of fall beyond the standard pumpkin spice, a new recipe from a home cook offers a savory take on the season's bounty. The dish, a free-form galette featuring roasted butternut squash, caramelized onions, and fontina cheese, was originally developed in 2007 and has recently been updated with fresh photographs. It serves six to eight people and requires about two hours from start to finish, making it a fitting centerpiece for a weekend dinner or a casual gathering.

The recipe emerged from a weekend trip upstate, where the cook and her husband sought the peak of autumn foliage, arriving a week early and finding the leaves still green. That experience, she notes, sparked a new appreciation for the early season and a flurry of recipe ideas. The galette itself was born from a desire to create a new filling for a beloved pastry dough, one that had previously been used for a wild mushroom and stilton version.

Why the Dough Matters

The foundation of this tart is a simple dough made with all-purpose flour, butter, sour cream or yogurt, and a touch of lemon juice. The cook describes it as consistently smooth and cold, yet pliable, a texture that invites repeated use. It's this reliability that led her to experiment with various fillings, ultimately settling on a combination of sweet roasted squash, savory onions, and a hint of cayenne for warmth.

The filling begins with a small butternut squash, peeled, diced, and roasted at 375°F with olive oil and salt until tender, about 30 minutes. Meanwhile, a large onion is slowly caramelized in butter with a pinch of sugar and salt, a process that takes about 20 minutes. The squash, onions, grated fontina, and fresh sage or thyme are then combined and cooled before being piled onto the rolled-out dough.

Assembling the Tart

Assembly is straightforward: the dough is rolled into a 12-inch round and transferred to a parchment-lined baking sheet. The filling is spread over the center, leaving a 1.5-inch border, which is then folded over the edges, pleating as needed. The galette bakes at 400°F for 30 to 40 minutes, until golden brown. After a brief rest, it can be served hot, warm, or at room temperature, making it a versatile option for entertaining.

The recipe's author notes that while the galette is a satisfying meal on its own, it pairs particularly well with a rich stout, a nod to the hearty flavors of the season. For those who prefer a different cheese, the original note suggests using any 'stinky cheese,' though fontina provides a mild, nutty counterpoint to the sweet squash.

This galette is a practical choice for home cooks looking to showcase autumn produce without the fuss of a traditional pie. Its free-form nature forgives imperfections, and the filling can be adjusted to taste. Whether served as a main course with a salad or as a side dish, it offers a taste of fall that is both rustic and refined.
