Instructions

Step 1: Prepare the Dough

- Cut in cold butter using a pastry cutter or fork until the mixture resembles coarse crumbs.
- Gradually add ice water, one tablespoon at a time, mixing until the dough just comes together.
- Form the dough into a disk, wrap it in plastic wrap, and refrigerate for 30 minutes.
Step 2: Caramelize the Onions
- Heat olive oil and butter in a skillet over medium heat.
- Add sliced onions, salt, and sugar. Cook, stirring occasionally, for 25-30 minutes until golden brown and caramelized.
- Stir in thyme leaves if using. Remove from heat and let cool slightly.
Step 3: 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 the dough to a parchment-lined baking sheet.
- Spread the caramelized onions over the dough, leaving a 2-inch border around the edges.
- Sprinkle Gruyere cheese evenly over the onions.
Step 4: Fold and Bake
- Fold the edges of the dough over the filling, pleating as needed to create a rustic look.
- Brush the crust with beaten egg for a golden finish.
- Bake for 40-45 minutes or until the crust is golden brown and crisp.
- Allow the galette to cool for 5-10 minutes before slicing and serving.

Frequently Asked Questions

Expand All:

Can I make the dough ahead of time?

Yes! The dough can be prepared up to 2 days in advance and stored in the refrigerator. Alternatively, you can freeze it for up to 3 months. Thaw in the fridge before rolling out.

What other cheeses can I use instead of Gruyere?

If Gruyere isn’t available, you can use Swiss cheese, Emmental, or even a sharp white cheddar for a similar flavor profile.

Can I make this galette gluten-free?

Absolutely! Substitute all-purpose flour with a gluten-free baking blend that includes xanthan gum for a gluten-free crust.

What can I serve with this galette?

Pair it with a fresh green salad, roasted vegetables, or a hearty soup like French onion or butternut squash for a complete meal.

Can I add other ingredients to the filling?

Yes! You can add sautéed mushrooms, roasted garlic, spinach, or even cooked bacon to customize the filling.

How do I store leftovers?

Store leftover galette in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) for 10-15 minutes for best results.

Can I make this galette vegan?

For a vegan version, use a plant-based butter alternative for the crust, replace the cheese with vegan cheese, and skip the egg wash or use a plant-based milk wash instead.

Is this galette good for meal prep?

Yes! You can caramelize the onions and prepare the dough in advance, then assemble and bake the galette when ready to serve.

What is the best way to caramelize onions?

Cook the onions low and slow in a mixture of butter and olive oil, stirring occasionally, until they turn golden brown. This process can take 25-30 minutes but adds incredible flavor.

Can I freeze the assembled galette before baking?

Yes, you can freeze the unbaked galette. Place it on a parchment-lined tray, freeze until firm, then wrap it tightly in plastic wrap and aluminum foil. Bake directly from frozen, adding an extra 10-15 minutes to the baking time.
