How To Make Blueberry Galette

1. Preheat oven to 400°F (200°C) and line a cookie sheet with parchment paper.
2. Prepare your pie crust. If using store-bought, unfold it. For homemade gluten-free crust, mix dry ingredients, cut in cubed butter, work in sour cream, add sparkling water to bring dough together, and chill for at least 2 hours. Roll out half the dough on a lightly floured surface to about a 12-inch circle.
3. Spoon blueberry filling into the center of the crust, leaving about a 2-inch border around the edges.
4. Gently fold the edges of the crust over the filling, pleating as needed to form a rustic round.
5. Whisk the egg with 2 tablespoons water to make an egg wash. Brush the folded edges with the egg wash and sprinkle with sugar.
6. Bake for 30–40 minutes, or until the crust is golden and the filling is bubbly.
7. Let the galette cool slightly before slicing. Serve warm, optionally with vanilla ice cream or whipped cream.

Blueberry Pie Filling — Quick Instructions

1. Whisk water and cornstarch together to make a slurry.
2. In a large pot over medium-low heat, combine blueberries, lemon juice, cinnamon, sugar, and the cornstarch slurry.
3. Cook, stirring occasionally, about 20 minutes until the mixture thickens. Cool before using. The filling stores in the refrigerator for up to two weeks.

Homemade Pie Crust — Quick Instructions

1. Combine gluten-free flour, baking powder, kosher salt, cinnamon, and allspice in a bowl.
2. Add cubed cold butter and sour cream. Use a pastry cutter or your hands to work the mixture until pea-sized pieces of butter remain.
3. Add sparkling water and mix until the dough just comes together. Wrap and refrigerate for 2 hours.
4. Divide the chilled dough in half. Roll one half to about 12 inches for the galette; reserve the other half for a top crust if making a double-crust pie.

Common Questions

Can I use frozen blueberries for the filling?

Yes. Add frozen blueberries directly to the filling without thawing. They can release a bit more liquid while cooking, so consider adding an extra tablespoon of cornstarch to help thicken the mixture.

How do I store leftover galette?

Store at room temperature for up to 2 days, or in the refrigerator for up to 4 days. Wrap tightly with plastic wrap or foil to keep it from drying out.

Can I reheat leftover galette?

Yes. Reheat in a 350°F (175°C) oven on a baking sheet for 10–15 minutes until warmed through. Microwave slices briefly if needed, but the crust may soften.

What if I don’t have a rolling pin?

No rolling pin required—press the dough into shape with your hands or use the smooth side of a clean bottle to gently roll and flatten the dough on parchment paper.
