Ingredients You’ll Need

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

14 ounces puff pastry – Thawed; Dufour brand is recommended for buttery layers.
2 tablespoons extra virgin olive oil – For sautéing.
1 medium leek – White and light green parts only, sliced into half-moons (about 1 cup).
1 pound mushrooms – Sliced; use a mix of cremini and shiitake for depth of flavor.
½ teaspoon kosher salt
½ teaspoon freshly ground black pepper
1 tablespoon balsamic vinegar – Adds a touch of tang and sweetness.
2 teaspoons fresh thyme leaves, plus more for garnish.
4 ounces goat cheese – Crumbled.
2 ounces Gruyère cheese – Freshly grated (about 1 cup).
1 egg – For egg wash to give the pastry a golden finish.

These ingredients come together to create a savory, rich filling inside a buttery, flaky crust.

Let’s Get Started

This galette comes together in just a few straightforward steps. Here’s how to make it:

Step 1: Preheat the Oven

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

Step 2: Prepare the Mushroom Filling

Heat the olive oil in a large skillet over medium heat.
Add the sliced leeks and sauté for about 3–4 minutes, until softened.
Stir in the mushrooms, salt, and pepper. Cook for 8–10 minutes, stirring occasionally, until mushrooms release their moisture and begin to brown.
Add the balsamic vinegar and thyme. Stir and cook for another minute, then remove from heat and let cool slightly.

Step 3: Roll Out the Puff Pastry

On a lightly floured surface, roll out your puff pastry into a rough 12-inch circle or oval. It doesn’t need to be perfect — that rustic look is part of a galette’s charm.
Transfer the rolled pastry to your prepared baking sheet.

Step 4: Assemble the Galette

Sprinkle the Gruyère cheese over the center of the pastry, leaving a 2-inch border around the edges.
Spoon the mushroom and leek mixture evenly over the cheese.
Dot the top with crumbled goat cheese.

Step 5: Fold and Brush

Gently fold the edges of the puff pastry over the filling, pleating as needed to create a border.
In a small bowl, beat the egg, then brush it over the exposed edges of the pastry.

Step 6: Bake

Bake for 25–30 minutes, or until the crust is golden brown and flaky.

Step 7: Garnish and Serve

Let the galette cool for about 5–10 minutes before slicing.
Sprinkle with more fresh thyme leaves, and serve warm or at room temperature.

Servings and Pairing

This mushroom galette yields about 4–6 servings as a main course, or 8–10 smaller slices as an appetizer.

Great Pairings

Arugula salad with lemon vinaigrette
Creamy soups like butternut squash or potato leek
A glass of Pinot Noir or dry white wine
Poached eggs for brunch — place one on top of a warm slice

It’s hearty enough to stand on its own, but pairs beautifully with fresh and light sides.

Variations

Want to switch it up? Try these simple substitutions and add-ons:

Swap the cheese – Use feta, blue cheese, or ricotta for a different flavor profile.
Add greens – Stir in sautéed spinach or kale with the mushroom mixture.
Make it spicy – Add red pepper flakes to the filling for a little kick.
Sweet and savory – Drizzle a bit of honey or fig jam on top before baking for contrast.
Use caramelized onions – Replace the leek with slow-cooked onions for a deeper flavor.

This galette is endlessly adaptable — make it your own!

Storage Tips

Leftovers? No problem. Here’s how to store and reheat:

Refrigerator: Store in an airtight container for up to 3 days.
Reheat: Warm in the oven at 350°F for 10–15 minutes to crisp up the crust. Avoid microwaving, which can make the pastry soggy.
Freezing: Not ideal once baked, but you can freeze unbaked assembled galettes for up to a month. Bake from frozen, adding a few extra minutes to the time.

FAQs

Can I use regular pie dough instead of puff pastry?

Yes! A galette made with homemade or store-bought pie dough will be a bit denser but still delicious.

Can I make this ahead of time?

Absolutely. Assemble the galette a few hours in advance, store in the fridge, and bake just before serving.

What mushrooms work best?

A mix of cremini and shiitake offers great depth, but feel free to use button, oyster, or whatever you have on hand.

How do I keep the crust from getting soggy?

Make sure your mushroom mixture has released most of its moisture before assembling. You can also sprinkle a bit of cheese or breadcrumbs before adding the filling to help absorb any excess liquid.

Can I make it vegetarian or vegan?

It’s already vegetarian. For vegan, use a plant-based puff pastry and swap the cheese for vegan alternatives. Use plant-based milk in place of egg wash.
