Why You’ll Love This Recipe

This galette brings together the naturally sweet creaminess of butternut squash with the crisp tartness of apple — all wrapped in a flaky, rustic pastry crust. It’s easy to assemble (no fancy tart pan needed), yet impressive enough to serve for a cozy dinner or a holiday gathering. The combination of squash and apple delivers warm, comforting fall flavors in a simple, homey package.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the crust:
1 1/4 cups all-purpose flour
Pinch of salt
8 tablespoons (1 stick) cold unsalted butter, diced
1 large egg, lightly beaten

For the filling:
1 medium butternut squash (about ¾ lb), halved, seeded (skin can remain on)
1 large baking apple (e.g. Rome or a tart variety), cored and cut into wedges (roughly 8 wedges)
1 small yellow onion (optional — adds savoriness), peeled, root end trimmed but intact
3 tablespoons unsalted butter, melted
2 teaspoons chopped fresh rosemary (or thyme, if preferred)
Salt and freshly ground black pepper to taste
2 tablespoons whole-grain mustard (for brushing the crust)
⅓ cup crumbled blue cheese or similar robust cheese (optional — for a savory finish)

Directions

1. Make the dough. In a food processor, pulse together the flour and salt. Add the cold diced butter and pulse about 10 times — the mixture should resemble coarse cornmeal, with a few pea-size bits of butter remaining. Add the beaten egg and pulse 1–2 more times, just until the dough begins to come together. (If it seems too dry, add 1 teaspoon cold water at a time, pulsing briefly.) Turn out the dough onto a flat surface, gently bring together by hand, shape into a disk, wrap in plastic, and refrigerate for at least 1 hour.
2. Prepare the filling. Meanwhile, halve and core the apple, cutting each half into about 8 wedges. Slice the squash and onion into wedges roughly the same thickness as the apple wedges. In a large bowl, combine the squash, apple, and onion. Add the melted butter, rosemary (or thyme), salt and pepper — toss gently to coat evenly.
3. Assemble the galette. Preheat oven to 400 °F (about 200 °C). On a lightly floured surface, roll the chilled dough into a roughly 12-inch circle. Transfer to a baking sheet lined with parchment paper. Brush the dough surface with the mustard, leaving about a 2-inch rim empty. Arrange the squash, apple, and onion in alternating overlapping circles from the outer edge inward. Fold and pleat the dough over the edge of the filling, forming a rustic free-form tart.
4. Bake. Bake in the preheated oven until the crust is golden brown and the squash & apples are tender and caramelized — about 55 minutes. If using cheese, remove the tart from the oven, scatter the cheese over the filling, and bake another 5 minutes until melted.
5. Cool briefly, then slice and serve.

Servings and timing

Makes about 6–8 servings.
Total time: ~1 hour 30 minutes (including dough chill time) — ~15 minutes prep, 1 hour chill, ~15 minutes assembly, ~55–60 minutes baking.

Variations

• Swap fresh herbs: try thyme or sage instead of rosemary.
• Skip the blue/strong cheese for a fully vegetarian and lighter galette, or replace with a mild cheese for subtlety.
• Add caramelized onions or sautéed garlic for extra savory depth.
• Use a pre-made pie crust to cut prep time drastically.
• For a sweeter twist, omit mustard and cheese, brush crust with a little melted butter, add a sprinkle of sugar or a drizzle of honey on top after baking.

Storage/Reheating

Refrigerate any leftovers in an airtight container for up to 3 days.
To reheat: warm slices in a preheated oven at 350 °F (≈175 °C) for about 10–15 minutes — the crust will crisp up nicely while filling warms through.

FAQs

What kind of apple works best?

A firm baking apple like Rome, Cortland or a tart apple works well — it holds its shape during baking rather than turning mushy.

Do I need to peel the butternut squash?

You can leave the skin on if it’s thin and tender — it adds texture and saves time. Otherwise, peel before slicing.

Can I make the dough ahead of time?

Yes — you can prepare the dough the night before and refrigerate (or freeze briefly). Just bring back to workable temperature before rolling out.

What if I don’t have fresh herbs?

Dried rosemary or thyme can work; use about 1 teaspoon instead of 2 teaspoons fresh.

Can I skip the cheese?

Absolutely — the galette is delicious without cheese, especially if you prefer vegetarian or lighter flavors.

Can I use store-bought pie crust?

Yes — using ready-made crust significantly reduces prep time and still yields a tasty rustic galette.

How to make the crust more flaky?

Use cold butter right from the fridge, work quickly, and avoid over-kneading; those coarse bits of butter help create flakiness when baked.

Can I add other vegetables?

Yes — thinly sliced onions, fennel, even thin zucchini or carrots can complement squash and apple. Just don’t over-fill or add too much moisture.

Can I make a sweeter version (dessert-style)?

Yes — omit mustard and cheese, substitute butter and herbs for a brush of melted butter and a sprinkle of sugar or honey after baking, maybe add a dash of cinnamon for warmth.

How to serve the galette?

Serve warm or at room temperature, on its own or with a side salad. Great as a vegetarian main, a side dish, or a cozy fall lunch.

Conclusion

This butternut squash and apple galette is rustic, comforting, and surprisingly easy to make — no special pans needed, just a simple dough rolled out and folded around seasonal produce. Whether you go savory (with herbs and cheese) or sweet (with butter and a hint of sugar or honey), it’s a versatile dish that captures the cozy flavors of autumn.
