Ingredients You’ll Need
The beauty of this galette lies in its straightforward ingredients, each bringing its own magic to the final creation. From the crisp fennel to the subtle sweetness of leeks and the nutty Gruyère, every component plays a crucial role in achieving that perfect balance of flavor and texture.
- All-purpose flour: Provides the sturdy base for a tender, flaky crust that holds everything together.
- Cold unsalted butter: Essential for flaky layers in the pastry, so keep it chilled until use.
- Ice water: Keeps the dough cool while bringing it together without making it tough.
- Salt (for pastry): Enhances the flavor of the dough and balances the richness of the butter.
- Medium fennel bulb: Adds that unique, slightly sweet anise flavor, which caramelizes beautifully.
- Medium leeks (white and light green parts): Brings softness and mild sweetness that pairs perfectly with fennel.
- Fresh thyme leaves (or dried): Lends an earthy herbal note that lifts the savory filling.
- Shredded Gruyère or mozzarella: Melts into a creamy, flavorful layer that binds the vegetables.
- Salt and black pepper: To taste, ensuring the flavors shine through perfectly.
How to Make Caramelized Fennel and Leek Galette with Gruyère Recipe
Step 1: Prepare the Dough
Start by mixing the all-purpose flour with a pinch of salt to season your pastry base. Cut in the cold, unsalted butter until the mixture resembles coarse crumbs—this creates the flaky texture you crave. Slowly drizzle in the ice water to bring the dough together, but be careful not to overwork it. Once it forms a ball, wrap it tightly in plastic wrap and chill for at least 30 minutes. This rest is crucial; it lets the gluten relax and the butter firm up, giving you that light, flaky crust every time.
Step 2: Caramelize the Fennel and Leeks
While your dough chills, thinly slice the fennel bulb and the white and light green parts of the leeks. In a skillet over medium heat, melt butter and add your vegetables with a sprinkle of salt and black pepper. Stir frequently as they cook down for 15 to 20 minutes until soft and golden. This caramelization is what builds the deep, sweet flavor foundation for the galette—don’t rush it!
Step 3: Assemble the Galette
Roll the chilled dough out into a roughly 12-inch circle on a floured surface. Carefully spread the caramelized fennel and leek mixture over the center, leaving about a 1-inch border all around. Evenly sprinkle the shredded Gruyère cheese on top—this creamy layer will melt beautifully in the oven. Fold the edges of the dough up and over the filling in rustic pleats. Working quickly here helps keep the pastry cool so it stays flaky.
Step 4: Bake to Golden Perfection
Preheat your oven to 400°F (200°C) and transfer the galette onto a baking sheet. Bake for 25 to 30 minutes, or until the crust is gorgeously golden and the cheese is bubbling underneath. The tantalizing aroma of browned butter, sweet fennel, and melted cheese will signal that your galette is ready to impress.
How to Serve Caramelized Fennel and Leek Galette with Gruyère Recipe
Garnishes
A sprinkle of freshly chopped herbs like parsley or thyme adds a pop of color and freshness that complements the rich galette beautifully. A light drizzle of high-quality olive oil right before serving can also wake up the flavors.
Side Dishes
Pair this galette with a crisp green salad tossed in a tangy vinaigrette to balance the richness. Roasted root vegetables or a simple soup can also round out your meal perfectly.
Creative Ways to Present
For a charming dinner party, serve the galette in personal-sized portions for easy handling and that homemade feel. You could also offer a variety of cheeses alongside to create a small tasting platter experience.
Make Ahead and Storage
Storing Leftovers
Leftover galette tastes even better the next day! Simply cover it tightly with plastic wrap or store in an airtight container in the fridge for up to two days.
Freezing
Wrap the fully baked galette in foil and place it inside a freezer-safe container. It can be frozen for up to one month without losing its flaky texture or delicious flavor.
Reheating
Reheat slices in a preheated oven at 350°F for 10-15 minutes to regain that crisp crust and warm, gooey cheese inside. Avoid microwaving, which can make the pastry soggy.
FAQs
Can I use other cheeses besides Gruyère or mozzarella?
Absolutely! While Gruyère provides a nutty flavor and melts beautifully, cheeses like Fontina, Comté, or even sharp cheddar can be delightful alternatives with their unique tastes and melting qualities.
Is it necessary to chill the dough before baking?
Yes, chilling the dough is key for achieving a flaky crust. It keeps the butter cold and prevents gluten from developing too much, which ensures tenderness and layers in the pastry.
Can I make the galette gluten-free?
You can try using a gluten-free all-purpose flour blend, but the texture may vary slightly. Adding a bit of xanthan gum might help with elasticity in the dough.
What can I substitute for fresh thyme?
If you don’t have fresh or dried thyme, rosemary or oregano make great herbal substitutes that complement the fennel and leek flavors nicely.
How do I know when the galette is done baking?
The crust should be a golden brown with some caramelized spots, and the cheese should be melted and slightly bubbly. If the edges brown too quickly, you can shield them with foil partway through baking.

Ingredients
Pastry
- 1 cup all-purpose flour
- 1/2 cup cold unsalted butter
- 3–4 tbsp ice water
- Salt (for pastry, to taste)
Filling
- 1 medium fennel bulb
- 2 medium leeks (white and light green parts)
- 1 tsp fresh thyme leaves (or 1/2 tsp dried thyme)
- 1 cup shredded Gruyère or mozzarella, room temperature
- Salt and black pepper to taste
Instructions
- Prepare the pastry dough: In a mixing bowl, combine the all-purpose flour and salt. Cut the cold unsalted butter into the flour mixture until it resembles coarse crumbs. Gradually add 3 to 4 tablespoons of ice water, mixing just until the dough comes together. Wrap the dough tightly in plastic wrap and chill it in the refrigerator for at least 30 minutes to allow it to firm up.
- Caramelize the fennel and leeks: While the dough chills, thinly slice the fennel bulb and leeks (white and light green parts only). Melt some butter in a skillet over medium heat, then add the fennel and leeks. Season with salt and black pepper. Cook for 15 to 20 minutes, stirring occasionally, until the vegetables are tender and caramelized to a golden color. Stir in fresh or dried thyme leaves towards the end for added aroma.
- Assemble the galette: On a lightly floured surface, roll out the chilled dough into a 12-inch circle. Spread the caramelized fennel and leek mixture evenly over the dough, leaving a 1-inch border around the edges. Sprinkle the shredded Gruyère or mozzarella cheese over the vegetables. Carefully fold the edges of the dough over the filling to create a rustic crust. Work quickly to ensure the pastry stays cold and flaky.
- Bake the galette: Preheat your oven to 400°F (200°C). Transfer the assembled galette onto a baking sheet lined with parchment paper. Bake in the preheated oven for 25 to 30 minutes, or until the crust is golden brown and the cheese is melted and bubbly. Remove from the oven and let it cool slightly before slicing and serving.
Notes
- For a flakier crust, make sure the butter and water are very cold and avoid overworking the dough.
- You can substitute Gruyère with mozzarella or other semi-hard cheeses to suit your preference.
- Be sure to remove the tough green parts of the leeks and clean them thoroughly to avoid grit.
- This galette is delicious served warm or at room temperature, making it perfect for entertaining.
- Store leftovers wrapped in foil and refrigerate for up to 2 days; reheat in a low oven to retain crispness.
