Why This Recipe Works

This gluten-free galette achieves a delightful texture thanks to the careful balance of gluten-free flours and the crucial addition of xanthan gum. These components work together to mimic the structure and elasticity typically provided by gluten, preventing a crumbly or dense crust. The method of pulsing the butter into the flour creates flaky layers, while the vinegar and egg contribute to tenderness and binding.

The simplicity of the galette format is key to its success; it’s intentionally rustic and forgiving. Unlike a pie, it doesn’t require precise crimping or a perfect shape. This allows the vibrant colors of the peaches and blueberries to shine. The cornmeal sprinkled on the parchment paper adds a subtle textural contrast and a beautiful, golden-brown finish to the bottom crust, enhancing the overall eating experience.

Step-by-Step Instructions

Prepare the Crust

1. Beat the egg and vinegar together in a small bowl.

2. Cube the unsalted butter and keep it cold.

3. Combine gluten-free flour blend, corn starch, sugar, xanthan gum (if using), and salt in the bowl of a food processor.

4. Pulse the dry ingredients a few times to ensure they are well mixed.

5. Add the cold butter cubes to the food processor.

6. Pulse until the mixture resembles coarse meal with small, pearl-sized pieces of butter visible.

7. With the food processor running, slowly drizzle in the beaten egg and vinegar mixture.

8. Continue processing until the dough just begins to come together into a cohesive ball.

9. Turn the dough out onto a clean surface and gently form it into a thin disk.

10. Wrap the dough disk tightly in plastic wrap.

11. Refrigerate the dough for at least 30 minutes to firm up.

Prepare the Filling

1. Cut the peaches in half, remove the pits, and slice them into approximately 1/4-inch thick pieces.

2. In a medium bowl, gently toss the fresh blueberries with 1 tablespoon of corn starch, 1-2 tablespoons of sugar, and 2 teaspoons of lemon juice.

Roll Out the Dough

1. Lightly moisten your countertop surface with a spray or splash of water. Lay two 24-inch long pieces of plastic wrap side-by-side, overlapping the long edges by about 2 inches, and smooth them flat.

2. Carefully unwrap the chilled dough disk and place it onto the center of the prepared plastic wrap.

3. Drape two more 24-inch long pieces of plastic wrap over the dough, ensuring they also overlap slightly.

4. Using a rolling pin, gently roll the dough out from the center towards the edges, rotating the piece as needed to maintain a circular shape. Aim for a thickness of about 1/8 inch.

5. Keeping the plastic wrap intact, carefully slide the rolled-out dough onto an upside-down baking sheet.

6. Chill the rolled-out dough in the refrigerator for another 20 minutes.

7. Preheat your oven to 350°F (175°C) during this chilling period.

Assemble the Galette

1. Line another upside-down baking sheet with parchment paper. Sprinkle a thin layer of cornmeal evenly over the parchment paper for texture.

2. Remove the top layer of plastic wrap from the chilled dough circle.

3. Carefully flip the dough over and place it, still on its remaining plastic wrap, onto the prepared parchment paper on the baking sheet.

4. Peel away the remaining bottom layer of plastic wrap from the dough.

5. Brush the entire surface of the dough lightly with the beaten egg wash.

6. Mound the prepared blueberries in the center of the dough, forming a circle about 5-6 inches in diameter.

7. Artfully arrange the sliced peaches around the blueberry center, extending outwards towards the edge of the crust, leaving a 3-4 inch border.

8. Gently fold the outer edge of the dough up and over the fruit filling, pleating and pressing as you go to create the rustic galette shape. Don’t worry if the dough tears; simply press it back together with your fingers.

9. Brush the folded crust edges generously with the remaining egg wash for a golden finish.

Bake the Galette

1. Bake the galette in the preheated oven for 40-45 minutes.

2. The galette is ready when the crust is a deep golden brown and the blueberry filling is visibly bubbling.

3. Allow the galette to cool on the baking sheet for at least 15-20 minutes before slicing and serving. This allows the filling to set properly.

Chef Tips for Perfect Results

• Ensure all dairy ingredients, especially the butter and any water used for the dough, are extremely cold. This is vital for a flaky gluten-free crust.

• Do not overwork the gluten-free dough. Overmixing can lead to a tough or gummy texture, negating the benefits of the gluten-free blend.

• Chill the dough sufficiently at each stage. Refrigeration allows the gluten-free starches to hydrate properly and the butter to solidify, both contributing to texture.

• Adjust the sugar in the fruit filling based on the natural sweetness of your peaches and blueberries. Taste a small piece of peach to gauge its sweetness.

• Use slightly underripe peaches if possible. They hold their shape better during baking and prevent an overly mushy filling.

• The cornmeal on the parchment paper is a subtle but impactful addition, providing a delightful rustic crunch to the galette’s base.

Common Mistakes to Avoid

• Using warm ingredients for the crust: Warm butter will melt prematurely, resulting in a greasy, dense crust instead of flaky layers. Always use cold butter and cold liquids.

• Overworking the dough: Gluten-free flours can become gummy when overmixed. Mix only until the dough just comes together to maintain a tender texture.

• Skipping the chilling times: The chilling periods are essential for gluten-free doughs. They allow the flours to hydrate properly and the butter to firm up, crucial for structure and flakiness.

• Under-baking the galette: Ensure the crust is deeply golden brown and the fruit filling is bubbling vigorously. Under-baking can leave the crust doughy and the filling too runny.

• Overstuffing the galette: Piling too much fruit in the center can make folding the crust difficult and may cause the filling to spill out during baking. Keep the filling contained within the designated area.

Variations and Substitutions

Ingredient	Substitution	Impact on Flavor
Gluten-free flour blend*	Specific GF flours like almond, oat, or buckwheat (adjust liquid)	Nutty or earthier notes; may alter texture.
Butter	Vegetable shortening or vegan butter sticks (chilled)	Slightly less rich flavor, potentially altered flakiness.
Egg (for binding/wash)	Aquafaba or plant-based egg replacer	May slightly affect binding and browning; test first.
Peaches	Nectarines, plums, firm pears, or apples	Changes fruit profile; adjust sugar and spices accordingly.
Blueberries	Raspberries, blackberries, cherries (pitted)	Adds different tartness or sweetness; may require altered cornstarch amounts.
Lemon juice	Lime juice or a splash of white wine vinegar	Tangier notes; lime offers a slightly more tropical profile.

Serving Suggestions and Pairings

This Peach-Blueberry Galette is best served warm, allowing the fruit filling to be lusciously gooey and the crust perfectly crisp.

Frequently Asked Questions

Can I substitute the gluten-free flour blend?

Yes, you can substitute with specific gluten-free flours like almond or oat flour, but be mindful of the liquid adjustments needed. The chosen blend significantly impacts texture and binding.

How do I know if the galette is fully baked?

The galette is fully baked when the crust is a deep golden brown and the fruit filling, particularly the blueberries, is actively bubbling. The juices should appear thickened, not watery.

My gluten-free crust is too crumbly, what did I do wrong?

Crumbly crust often results from not enough liquid or over-chilled butter. Ensure your dough has enough moisture, and that the butter was properly incorporated and kept cold throughout the process.

Can I make the dough ahead of time?

Yes, the galette dough can be made up to 2 days in advance and stored in the refrigerator. Ensure it is tightly wrapped to prevent drying out.

What is the best way to serve a gluten-free peach blueberry galette?

Serve the galette warm or at room temperature. It pairs wonderfully with vanilla ice cream, whipped cream, or a light dusting of powdered sugar for an appealing presentation.
