One rainy afternoon, I decided to try my hand at creating a galette that would elevate my usual onion tart. After experimenting with caramelization techniques, I learned that low and slow is the key to enhancing the natural sweetness of onions. It truly transforms their flavor profile.

While making the crust, I discovered that using cold butter and chilling the dough before rolling it out yields a flakier texture. This galette has quickly become a favorite, and I love serving it warm with a side salad for a delicious weeknight dinner.

Mastering the Dough

Getting the dough just right is crucial for a successful galette. Using cold butter prevents it from melting and ensures a flaky texture. When blending the butter into the flour, leave some larger pieces; this will create pockets of steam, enhancing flakiness. If the dough feels too soft after adding the ice water, refrigerate it for an additional 10-15 minutes before rolling out to maintain its shape during baking.

For those without a pastry cutter, your hands or a food processor can also work well. Just be cautious not to overwork the dough, as this can lead to a tough crust. If you're aiming for a whole-grain variant, feel free to substitute half of the all-purpose flour with whole wheat flour. This will impart nuttiness and depth while maintaining the structure of the galette.

Perfecting the Filling

Caramelizing the onions is an essential step that brings out their natural sweetness. Aiming for a low and slow cooking method, keep the heat around medium-low to avoid burning. If your onions start to stick, add a splash of water to deglaze the pan and lift the fond, which adds flavor. When finished, the onions should be a rich, deep golden color, a sign that their sugars have developed beautifully.

The addition of goat cheese not only enhances flavor but also provides creaminess that balances the sweetness of the onions. If you're looking for a dairy-free alternative, consider using a plant-based cream cheese. Additionally, feel free to experiment with herbs like rosemary or sage for a layer of earthy flavor that complements the onions wonderfully. Just remember, fresh herbs should be added toward the end to maintain their vibrant taste.

Ingredients

For the Galette

1 ½ cups all-purpose flour
½ teaspoon salt
½ cup unsalted butter, cold and cubed
4-5 tablespoons ice water

For the Filling

3 large onions, thinly sliced
2 tablespoons olive oil
½ teaspoon salt
1 teaspoon sugar
¼ cup goat cheese, crumbled
1 tablespoon fresh thyme leaves
1 egg, beaten for egg wash

Instructions

Prepare the Dough

Shape it into a disk, wrap in plastic, and chill in the refrigerator for at least 30 minutes.

Caramelize the Onions

In a large skillet, heat the olive oil over medium-low heat. Add the sliced onions and salt, cooking slowly for about 25-30 minutes until they are golden brown and caramelized. Stir in the sugar in the last 5 minutes of cooking to enhance sweetness.

Assemble the Galette

Preheat your oven to 400°F (200°C). Roll out the chilled dough on a floured surface into a 12-inch circle. Transfer it to a baking sheet. Spread the caramelized onions over the dough, leaving a 2-inch border.

Sprinkle the goat cheese and thyme over the onions.

Bake

Fold the edges of the galette up and over the filling, pleating as necessary. Brush the crust with the beaten egg. Bake for 30-35 minutes or until the crust is golden and the filling is bubbly.

Serve

Allow the galette to cool slightly before slicing. Serve warm or at room temperature. Enjoy!

Pro Tips

For added flavor, consider mixing in some grated Parmesan cheese with the goat cheese or adding a drizzle of balsamic reduction before serving.

Storage and Make-Ahead Tips

If you plan on preparing this galette in advance, the dough and filling can both be made ahead of time. The dough can be wrapped tightly in plastic and stored in the refrigerator for up to 3 days or frozen for up to a month. Just be sure to allow it to thaw in the refrigerator overnight before rolling it out. The caramelized onions can be prepared 1-2 days ahead and stored in an airtight container in the fridge, making assembly a breeze when ready to bake.

Leftover galette can be stored in the refrigerator for up to 3 days. To reheat, place it in a preheated oven at 350°F (175°C) for about 10-15 minutes until warmed through. Avoid using the microwave, as it can make the crust soggy. If you have leftovers of just the filling, it can also serve as a delicious topping for pizzas or mixed into scrambled eggs for a flavorful breakfast.

Serving Suggestions

This Savory Caramelized Onion Galette pairs beautifully with a simple green salad dressed in a light vinaigrette. The freshness of the salad contrasts nicely with the rich filling, enhancing the overall dining experience. If you’re hosting a gathering, consider serving this galette alongside a charcuterie board; its flavors complement cured meats and robust cheeses wonderfully.

For a unique twist, serve individual slices of galette with a dollop of crème fraîche or a drizzle of balsamic reduction. These additions offer creaminess and acidity that elevate the dish. If you’re feeling adventurous, try adding a sprinkle of crushed red pepper flakes for a touch of heat, enhancing the flavor profile of the galette.
