This grape blueberry galette is unfussy in the way all good desserts tend to be: built on a flaky, buttery crust and filled with grapes and blueberries that burst and become jammy in the oven, turning syrupy at the edges while the crust turns golden and crisp.
One of my favorite desserts to whip up is a rustic galette. The name says it all: rustic. When a dessert’s premise starts with rustic, it automatically takes the weight off your shoulders. There’s no room for precision here, for perfectly lined layers or a glossy finish.
In this one, grapes bring density and sweetness once roasted, almost like they’ve been concentrated down into something richer than fresh fruit has any right to be. Blueberries step in with acidity, breaking up the texture so the galette never feels heavy.
Together, they create a filling that tastes like late summer being compressed into a single slice.
The Dough
This is a typical all-butter flaky dough, enriched with a little bit of heavy cream. When making galette dough, keep two things in mind: all ingredients must remain cold, and you must work quickly so as not to overwork it.
This sounds scarier than it actually is. Most people use a food processor when making dough, but I prefer to use my hands. I think working quickly with a fork and your fingertips is the best way to assess it (how wet or dry it is, etc.).
People often advise against over-hydrating galette dough, since water keeps it from being flaky — typically, you want your galette dough to be on the drier side. But don’t worry if it doesn’t look shaggy, it will most likely be okay.
My advice is to add water a little bit at a time, mixing as you go. It will come together in big clumps, so transfer those to a working surface and repeat the process with the remaining mixture in the bowl until you’re done.
You want to add just enough water to keep it together, so your dough will look rather dry at this stage. As it chills in the fridge it hydrates, and as you roll it out, it starts to come together more cohesively. What I’m trying to say is that, whether slightly under- or over-hydrated, it will be fine.
The Filling
Blueberries are a popular galette filling, grapes are the outliers here. I happen to think grapes are far underappreciated, and maybe this is my attempt to do them justice. When baked, grapes caramelize and their sweetness intensifies. They collapse into a jammy consistency with a wine-adjacent taste. So why aren’t they present in more desserts?!
Since they’re about 80% water, they need to be cooked before going onto the dough so that some of that water is released. It’s imperative you use seedless grapes for this, as there’s nothing worse than biting into an accidental seed, let alone dozens of them. Any seedless red grape variety will work.
Together with the blueberries, they make a vibrant, sweet-and-tangy filling that’s full of antioxidants, and they complement each other very nicely.
Sitting atop a rich, flaky, buttery pastry and served with a dollop of softly whipped heavy cream, this is a dessert that’s all about simplicity.
Recipe Notes
You can use a mix of green and red grapes for more variation in sweetness, just make sure to use seedless grapes.
The dough can be made ahead and chilled overnight.
When making the dough, add water one tablespoon at a time. The dough should look “shaggy” and barely hold together when you squeeze a handful. If it’s sticky, you’ve added too much; if it’s sandy, you need a splash more.
Bake Until Deeply Golden: Don’t pull it out too early; wait until the crust is a dark, toasted golden brown and the bottom is rigid enough to be lifted with a spatula without sagging, as the base often needs a few extra minutes beyond what the top suggests.
FAQ
Why did my galette dough turn tough instead of flaky?
This usually comes down to gluten development. Overmixing or over-kneading the dough strengthens gluten too much, which leads to toughness instead of tenderness. A galette dough should be mixed just until it holds together — it should still look shaggy.
Why is butter so important in galette dough, and what am I actually looking for when I mix it in?
You’re not trying to fully incorporate the butter. You want visible pieces of butter distributed through the flour. During baking, those butter pieces melt and release steam, which creates the flaky layers.
My dough keeps shrinking when I roll it out, what am I doing wrong?
That’s usually gluten tension. It means the dough hasn’t rested long enough after mixing. Resting allows the gluten strands to relax so the dough stops resisting being stretched. If it shrinks, let it sit for 10-15 minutes before rolling again.
Why does galette dough crack at the edges when I roll it?
Cracking usually means the dough is too cold or slightly under-hydrated. Letting it sit briefly at room temperature solves most cracking issues.

Grape Blueberry Galette
Ingredients
Dough:
- 155g (1¼ cups) all-purpose flour, plus more for surface
- 1 tbsp sugar, plus more for finishing (or use Turbinado sugar if you have it)
- 1 tsp kosher salt
- 142g (¾ cup) unsalted butter, cold
- 25g (1½ tbsp) heavy cream, cold
- 45g (3 tbsp) ice water, plus more as needed
- 1 egg beaten, for egg wash
Filling:
- 400g (2½ cups) seedless red grapes
- 130g (1 cup) blueberries
- ¼ cup granulated sugar
- ¼ cup cornstarch
- zest of 1 lemon
- pinch of salt
Instructions
Dough:
- Whisk flour, sugar, and salt in a medium bowl to combine.
- Cut half the butter into cubes and thinly slice the remaining half. Add to the bowl and toss to coat the butter. Using your fingers, quickly smash the cubes and slices into smaller, flat, pea-sized pieces.
- Drizzle in the heavy cream, mixing with a fork. Add the ice-cold water, one tablespoon at a time, mixing until the dough just starts to hold together in large clumps.
- Transfer the clumps to a piece of plastic wrap, leaving the dry bits in the bowl. Drizzle more ice-cold water into the dry bits, just until they hold together when squeezed in your hand. Add this to the dough on the plastic wrap.
- Wrap tightly into a square, pushing the dough into the into corners and pressing out any air pockets. Chill for 2 hours or overnight.
Filling:
- Add the grapes to a medium saucepan over medium-high heat. Press them down with the back of the spoon so they burst, and cook until they have broken down into juice, about 10 minutes. Transfer to a bowl and allow to cool completely.
- Preheat the oven to 425°F/ 220°C. Line a baking sheet with parchment paper.
- If the grapes have released too much juice, discard some of it. Whisk in the sugar, cornstarch, lemon zest, and salt to combine.
- Let the dough sit at room temperature for about 4 minutes to soften. On a lightly floured surface, roll it out into a ¼-inch-thick circle. Transfer the dough to the prepared baking sheet.
- Spoon the filling into an even layer in the center of the circle, leaving 2 inches of uncovered dough all around. Fold the edges over the filling, pleating as needed to encase it, applying enough pressure to seal.
- Brush the dough with the egg wash and sprinkle with sugar or turbinado sugar. Bake for 25-35 minutes, until the crust and bottom are golden brown. Serve.
