Rustic mushroom, Swiss chard and leek galette with goat cheese, mozzarella and fresh thyme wrapped in a flaky sour cream butter crust. A savory transition-to-fall dinner.
Rustic Mushroom, Swiss Chard & Leek Galette with Goat Cheese
We are slowly transitioning from summer to fall in Southern California. The leaves on our trees are turning and falling, Some nights are cool and crisp, and some are overly hot as the weather changes and trys to settle into the new season. And I’m ready for deeper flavors and a few heartier dishes, but when it’s still warm outside, I’m not quite ready for stews, roasts and heavy comfort food.
That’s when I turn to recipes like this Rustic Mushroom, Swiss Chard & Leek Galette.
It has all those flavors that start making me think about fall—earthy mushrooms, Swiss chard, sweet leeks, garlic and fresh thyme—but it still feels light enough for a warm October evening. The flaky sour cream butter crust makes it feel special, while the vegetables keep the whole thing grounded and fresh.
And then there’s the goat cheese.
Little dollops scattered over the top melt into creamy, tangy pockets with lightly toasted edges. Combined with the mozzarella tucked into the filling, it gives this rustic galette just enough richness without making it feel too heavy.
This is pretty much how we like to eat during this time of year: a little heartier, a little deeper in flavor, but still somewhere between summer and fall.
Enjoy!
Ingredients
For the Tart Pastry
- All-purpose flour — The foundation for a tender, rustic crust.
- Cold butter — Gives the pastry its flaky texture and rich flavor.
- Sour cream — Adds tenderness and a little tang to the crust.
- Lemon juice — Just enough to brighten the pastry and balance its richness.
- Cold water — Helps bring the dough together without overworking it.
- Salt — Essential for bringing out the flavor of the crust.
For the Filling
- Baby bella mushrooms — Earthy and savory, they give the galette its deep fall flavor.
- Swiss chard — Adds tender greens and a beautiful pop of color.
- Leeks — Their mild, sweet onion flavor is perfect with mushrooms and thyme.
- Garlic — Adds another layer of savory flavor.
- Fresh thyme — One of my favorite herbs for this time of year.
- Mozzarella — Melts into the vegetables for a creamy, cohesive filling.
- Olive oil — For sautéing the vegetables.
- Salt & black pepper — Just enough seasoning to let the vegetables shine.
For the Topping
- Goat cheese — Small dollops melt and brown on top, adding tangy, creamy bites throughout the galette.
Equipment
- Large skillet — My go-to heavy skillet works beautifully for sautéing the vegetables.
- Rolling pin — For rolling the pastry into a rustic 12-inch circle.
- Parchment paper — Makes transferring and baking the galette easy.
- Baking sheet — A rimmed sheet is ideal for catching any melted cheese or juices.
- Pastry cutter — Helpful for cutting the cold butter into the flour.
My Go-To's
- Pastry cutter - a great way to easily cut in the butter into the flour.
- Baking Sheet - having different sizes in your arsenal allow you to easily choose the correct size for what you are baking.
Let's Make It Together
First, we'll make the pastry. Cut the cold butter into the flour and salt until you have coarse crumbs, then gently work in the sour cream, cold water and lemon juice. Once the dough comes together, wrap it up and let it chill while you make the filling.
The filling comes together quickly in one skillet. Brown the mushrooms first so they have a chance to develop some good color, then add the Swiss chard, leeks, garlic and thyme. Once the vegetables are tender, let them cool slightly before stirring in the mozzarella.
Roll the chilled dough into a rough circle—no need to make it perfect. Spoon the filling into the center, leaving a border around the edge, then fold the pastry up and over the filling, pleating it as you go.
Dot the top with goat cheese and into the oven it goes. About 30–40 minutes later, you'll have a golden, rustic galette with crisp pastry and a savory, cheesy vegetable filling.
Perfecting the Cooking Process
The key to a great galette is keeping the filling from becoming watery. Give the mushrooms time to brown and release their moisture before adding the greens and leeks. Let the cooked filling cool slightly before adding the mozzarella and placing it on the pastry. This keeps the crust flaky and helps the galette bake up beautifully golden instead of soggy.
Add Your Touch
- Try another mushroom: Cremini, white mushrooms or a wild mushroom blend would all work beautifully.
- Change the cheese: Gruyère or fontina would be delicious in place of the mozzarella.
- Add a little heat: A pinch of red pepper flakes would bring a subtle warmth.
- Make it more herb-forward: Add a little fresh rosemary along with the thyme.
- Finish with freshness: A little lemon zest scattered over the finished galette would be lovely.
Set the Mood
A good meal deserves a great setting. Here are a few ways to set the mood when serving this dish.
This Rustic Mushroom, Swiss Chard & Leek Galette is exactly the kind of recipe I want to make when summer is slowly giving way to fall.
It's savory, earthy and comforting, but it doesn't feel heavy. The flaky lemon-scented crust, tender vegetables, melted mozzarella and little pockets of goat cheese make it feel like something special without requiring a complicated dinner.
It's a good reminder that you don't have to jump straight into full-on fall cooking. Sometimes the best recipes are the ones that live right in between the seasons.
If you're enjoying this kind of hearty-but-not-heavy cooking, take a look at my Mediterranean White Bean Skillet next. It's another cozy, vegetable-forward dish that's satisfying enough for cooler days while still feeling fresh and bright.

Before You Start
Can I make the pastry ahead of time?
Absolutely. The pastry can be made earlier in the day and kept refrigerated until you're ready to assemble the galette.
Can I use spinach instead of Swiss chard?
Yes. Spinach will work, although it cooks more quickly and has a softer texture than Swiss chard.
Can I use a different cheese?
Definitely. Gruyère, fontina or another good melting cheese would work well in the filling.
Can I make the galette ahead of time?
It's best served warm from the oven, but you can assemble it ahead and refrigerate it until you're ready to bake. Allow a little extra baking time if the galette is going directly from the refrigerator to the oven.
Why do I need to cook the mushrooms first?
Mushrooms release quite a bit of moisture as they cook. Browning them first helps concentrate their flavor and keeps excess moisture from making the galette soggy.
Can I freeze the galette?
For the best pastry texture, I'd recommend baking it fresh rather than freezing the assembled galette. Leftovers can be refrigerated and gently reheated.
