Flaky puff pastry meets sautéed onions, tart apple, thyme, and plant-based cheese in this rustic savory onion and apple galette that’s simple yet elegant.
Savory Onion and Apple Galette: Easy Elegance with Seasonal Produce
The idea of a galette has been in my head for a while, and with autumn right around the corner it finally felt like the right time to share one. Honestly, I had a sheet of puff pastry left over from the holidays that I’d been holding onto, and this recipe was the perfect way to use it. My Savory Onion and Apple Galette came together naturally—I always find myself leaning toward the onion and apple combo because the flavors just balance so well. I wanted to keep this one savory but added a little sweetness with a Dijon-maple base and a touch of maple mixed into the milk for brushing the edges. And please don’t skip that final sprinkle of flaky sea salt when it comes out of the oven—it makes every bite pop. This galette is such a great fall dish, whether you serve it for dinner, lunch, or as a light starter to a meal.

What Is a Galette?
A galette is a rustic, free-form pastry that originated in France. Unlike pies or tarts, galettes don’t require a pan or mold—just roll out the dough, pile on the filling, and fold the edges over. They can be sweet or savory, making them a versatile way to showcase seasonal produce. This savory version leans into autumn flavors, combining onion and apple with herbs and cheese, all wrapped up in buttery puff pastry.
Ingredient Highlight: Puff Pastry
Puff pastry is the real game-changer here. With its flaky layers and buttery flavor, it gives the galette that golden, bakery-style finish without the time or effort of homemade dough. Let the pastry thaw just enough so it unfolds easily—too cold and it cracks, too warm and it gets sticky. For vegans, be sure to grab a dairy-free version (many store brands are accidentally vegan, but always check the label). While traditional French galettes are typically made with a hand-rolled pastry, this version takes an inspired modern twist, keeping things easy without losing any of that rustic charm.
Madly Delicious Must-Know Tips & Questions
- Border is key. Leave a 1-inch border when adding the filling so the edges fold neatly.
- Don’t skip the salt. A final sprinkle of flaky sea salt after baking elevates all the flavors.
- Best the day of. This galette is at its flakiest when fresh, but can be reheated in the oven the next day.
Can I make this ahead?
Yes—prep the onions ahead and store them in the fridge. When ready, assemble and bake the galette fresh.
Do I need to peel the apples?
Peeling gives a cleaner texture, but you can leave the skin on for a more rustic look.
What cheese works best?
A soft, melty plant-based cheese like brie-style, white cheddar, or even a Gruyère-style works well in this galette.
Let’s Dish About Galettes: Did You Know?
Galettes are considered one of the most traditional rustic French pastries, dating back centuries. While the sweet versions with stone fruit or apples are popular in the U.S., savory galettes are just as classic in France—often filled with potatoes, onions, or cheese. The word “galette” itself comes from the Old French word galet, meaning a flat, round stone—fitting for this free-form flat pastry.

Savory Onion and Apple Galette (Puff Pastry Shortcut)
Equipment
- Medium or large baking sheet
Ingredients
- 1 sheet thawed puff pastry (many store-bought varieties are accidentally vegan)
- 2 tbsp olive oil
- 1 large yellow onion, halved and thinly sliced into half moons
- Salt, to taste
- 1 tbsp Dijon mustard
- 2 tsp pure maple syrup, divided
- 2-3 fresh thyme sprigs
- 1 Granny Smith apple
- ¼ cup grated plant-based cheese (I used a brie but it was more like a white cheddar)
- 1 tbsp unsweetened plant-based milk or creamer
- Flaky sea salt, to finish
Instructions
- Prep the puff pastry: Remove 1 sheet puff pastry from the fridge and let it sit out for 10–20 minutes, until just soft enough to unfold without cracking. Line a baking sheet with parchment paper or a baking liner and set the pastry on top.
- Cook the onions: Meanwhile, heat 2 tbsp olive oil in a skillet over medium-high heat. Add the sliced onion and a pinch of salt, then sauté for about 10 minutes, stirring occasionally, until lightly browned. (We’re softening and browning, not fully caramelizing.) Remove from heat.Preheat oven to 400°F (200°C).
- Make the mustard base: In a small bowl, stir together 1 tbsp Dijon mustard and 1 tsp maple syrup. Brush the mixture evenly over the unfolded puff pastry, leaving about a 1-inch border around the edges to make folding easier. Sprinkle the leaves from 1 thyme stem over the mustard base.
- Prep the apples: Peel and slice the Granny Smith apple into thin slices, about ⅛-inch thick. Tip: Don’t slice too early or they will brown.
- Assemble the galette: Layer about three-quarters of the onions over the brushed pastry. Arrange the apple slices in a circular pattern on top. Scatter over the remaining onions, a few leaves from the thyme sprig, and sprinkle with ¼ cup grated plant-based cheese.Tip: If you’d like a perfect round shape, you can trim the pastry corners before folding them in.
- Fold and brush: Gently fold the edges of the pastry up over the filling to form a rustic galette shape. In a small bowl, mix 1 tbsp plant-based milk or creamer with 1 tsp maple syrup, then brush over the folded edges.
- Bake: Bake for 18–22 minutes, or until the pastry is golden brown and crisp.
- Finish and serve: Remove from the oven and sprinkle with flaky sea salt and a few fresh thyme leaves. Let cool slightly before cutting into 4–6 slices.
The perfect fall appetizer! Absolutely delicious!
