How to Make Sweet Potato and Sage Puff Pastry Galette

This rustic tart is surprisingly simple to make. Follow these steps for a golden, flaky galette with perfectly roasted sweet potatoes.

Step 1: Prepare the Sweet Potatoes

Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.

Peel the sweet potatoes and slice them thinly, about 1/8-inch thick. A mandoline slicer works great for this, but a sharp knife also works. The key is to get them thin and even so they cook through properly.

In a large bowl, combine the sweet potato slices, olive oil, chopped sage, minced garlic, smoked paprika, salt, pepper, and red pepper flakes (if using). Toss well to coat each slice evenly. Set aside.

Step 2: Prepare the Puff Pastry

Lightly flour your work surface and roll out the thawed puff pastry sheets slightly to smooth out the creases. For a large galette, roll the two sheets together to form one large rectangle, about 12 x 16 inches. Alternatively, you can make two smaller galettes using one sheet each.

Place the pastry on the prepared baking sheet (the parchment paper can go directly onto the sheet).

Step 3: Assemble the Galette

Arrange the sweet potato slices on the pastry in an overlapping circular or spiral pattern, leaving a 2-inch border around the edges. Start from the center and work your way out, overlapping the slices slightly. The design is up to you – a spiral pattern looks particularly beautiful.

Sprinkle the crumbled goat cheese evenly over the sweet potatoes.

Fold the edges of the pastry up and over the filling, pleating as you go to create a rustic border. The center of the galette should be open, with the filling visible.

Step 4: Egg Wash and Bake

In a small bowl, whisk the egg with the milk or water. Brush the folded edges of the pastry with the egg wash. This gives them that beautiful glossy, golden-brown finish.

Bake for 22-25 minutes, or until the pastry is puffed up and deep golden brown and the sweet potatoes are tender and caramelized at the edges.

Step 5: Garnish and Serve

Remove the galette from the oven and let it cool on the baking sheet for 5-10 minutes. Garnish with fresh sage leaves and a sprinkle of flaky sea salt.

For an extra touch of sweetness and elegance, drizzle with a little honey or balsamic glaze just before serving. Slice and serve warm or at room temperature. It’s delicious on its own or with a simple green salad.

Tips for the Best Sweet Potato Galette

Slice the sweet potatoes thinly: Thin, even slices are crucial for ensuring the sweet potatoes cook through in the same time it takes for the pastry to bake. If your slices are too thick, they may remain undercooked.

Keep the pastry cold: Puff pastry needs cold butter to create steam and flaky layers. If your dough gets too warm while assembling, pop it back in the fridge for 10-15 minutes before baking.

Don’t overfill: While it’s tempting to pile on the sweet potatoes, too much filling can make the galette soggy and difficult to fold. A single layer of overlapping slices is perfect.

Use fresh sage: Fresh sage has a wonderful earthy flavor that pairs beautifully with sweet potatoes. If you only have dried sage, use 1 teaspoon, but fresh is definitely preferred.

Get creative with the topping: The goat cheese adds tanginess, but you can also try feta, ricotta, or even a sprinkle of Parmesan for different flavor profiles.

Delicious Variations to Try

• Butternut Squash and Rosemary Galette: Replace the sweet potatoes with butternut squash and use fresh rosemary instead of sage. Add caramelized onions for extra sweetness.
• Mushroom and Thyme Galette: Sauté sliced mushrooms with garlic and thyme, then arrange on the pastry with crumbled goat cheese. It’s a rich, earthy variation.
• Tomato and Basil Galette: Use sliced heirloom tomatoes, fresh basil, and mozzarella for a summer-inspired galette. Add a drizzle of balsamic glaze before serving.
• Apple and Cheddar Galette: For a sweet-savory version, use thinly sliced apples, sharp cheddar cheese, and a sprinkle of thyme. It’s perfect for fall.
• Zucchini and Pesto Galette: Layer thinly sliced zucchini with basil pesto and Parmesan cheese. It’s a fresh, vibrant option for summer.

How to Store and Reheat

Storing: Baked galette can be stored in an airtight container in the refrigerator for up to 4 days. It’s delicious cold, at room temperature, or reheated.

Reheating: For best results, reheat slices in a 350°F oven for 5-7 minutes until warm and crispy again. A toaster oven works great. The microwave will make the pastry soft, so it’s best to avoid it.

Freezing: Unbaked assembled galette can be frozen on a baking sheet, then transferred to a freezer bag for up to 3 months. Bake directly from frozen, adding 8-10 minutes to the baking time. You can also freeze baked galette and reheat slices in the oven when ready.
