Gluten-Free Blackberry Galette Ingredients & Substitutions

This gluten-free blackberry galette keeps things simple with just a handful of pantry staples. Each ingredient plays an important role—from a buttery, flaky crust to a juicy berry center. Here’s what you’ll need and how you can make easy swaps to fit your preferences or pantry.

For the Crust

• Gluten-Free 1:1 Baking Blend – Forms the base of the crust and gives structure. Look for a blend that includes xanthan gum for elasticity. Sub with all-purpose flour (if not gluten-free) or another GF blend you trust.
• Granulated Sugar – Adds a touch of sweetness to balance the berries and helps the crust brown. You can use coconut sugar, organic cane sugar, or monk fruit.
• Salted Butter – Creates those gorgeous flaky layers when folded into the dough. Replace with plant-based butter sticks for a vegan option.
• Cold Water – Brings the dough together without melting the butter. Cold is key for keeping the crust flaky.

For the Filling

• Blackberries (Fresh or Frozen) – If using frozen, do not thaw! Any type of berry will work in this recipe.
• Granulated Sugar – Sweetens the berries and helps them break down into a jammy filling. You can swap it with cane sugar, coconut sugar, monkfruit, or your favorite sweetener.
• Cornstarch – Thickens the berry juices as the galette bakes to avoid a soggy crust. Use arrowroot starch or tapioca starch if you don’t or can’t have cornstarch.
• Lemon Juice – Fresh is always best, but lime juice or a splash of apple cider vinegar will work if you don’t have any lemon juice.

Optional Topping

• Egg – Gives the crust a shiny, golden finish. Substitute plant-based milk with a teaspoon of maple syrup for a vegan option.
• Granulated Sugar & Chopped Almonds – Adds sparkle and crunch to the crust.

How to Make a Gluten-Free Blackberry Galette

This rustic galette might look fancy, but it’s incredibly simple to pull together. Follow these step-by-step instructions for a buttery crust and juicy berry filling.

Crust

1. Mix the dry ingredients – In a large bowl, whisk together the gluten-free flour blend, sugar, and salt.
2. Cut in the butter – Add cold, cubed butter and toss to coat. Use your fingers, a fork, or a pastry cutter to work the butter into the flour until the pieces are about the size of walnut halves.
3. Add cold water – Pour in the cold water and gently mix. The dough will look dry, but keep pressing and squeezing until it starts to come together.
4. Shape and chill – Press the dough into a shaggy ball with as few dry bits as possible. Form into a disc, wrap in plastic, and chill for at least 30 minutes.
5. Roll and fold – On a lightly floured surface, roll the dough into a rectangle. Fold it like a letter: bottom third up, top third down. Rotate 90º and repeat the roll and fold 4–6 times for maximum flakiness.
6. Chill again – Wrap the folded dough in plastic and chill for another 30 minutes. If it gets soft while folding, chill in between.

Filling

Helpful hint: If you are using frozen blackberries, do not make the filling until the pie crust has been rolled, the oven is preheated, and you are ready to bake.

1. Combine the ingredients – In a large bowl, mix the blackberries, sugar, cornstarch, and lemon juice until evenly coated.
2. Use fresh or frozen berries – If using frozen berries, don’t thaw them first—just toss them in as-is.

Assembly

1. Preheat the oven – Set the oven to 400ºF and place a rack in the lower-middle position.
2. Roll the dough – On a lightly floured piece of parchment, roll the chilled dough into a 13–14 inch circle.
3. Add the filling – Spoon the blackberry mixture into the center of the dough, leaving a 2-inch border all around.
4. Fold the edges – Gently fold the edges of the dough over the filling, letting them overlap naturally. Pinch any cracks closed to prevent leaking.
5. Brush and sprinkle – Brush the crust with whisked egg (or plant-based milk) and sprinkle with sugar and sliced almonds if desired.
6. Bake until golden – Slide the parchment paper and galette onto your baking sheet. Bake for 40–45 minutes, or until the crust is golden and the filling is bubbling in the center.
7. Cool and serve – Let the galette cool for 15–20 minutes before slicing. Serve warm for maximum deliciousness.

Helpful Tips & Tricks

A few simple tips can make all the difference when it comes to getting that perfect flaky crust and juicy berry filling. Here’s how to make sure your galette turns out golden, crisp, and delicious every time.

• Don’t skip the chill time—cold dough = flaky crust!
• If your dough starts feeling too soft while rolling or folding, pause and chill it again.
• Frozen berries are great in this recipe—just toss them straight in, no thawing needed.
• For a crisp crust, make sure the filling is bubbling in the center before pulling it from the oven.

Frequently Asked Questions

Can I make it ahead of time?

Yes! The dough can be made a day in advance and stored in the fridge. Allow the dough to rest at room temperature for 5 minutes before rolling. The baked galette is best the day it’s made, but keeps well for up to 2 days.

Is this galette vegan?

It can be! Just use plant-based butter and brush the crust with non-dairy milk instead of egg.

How do I store leftovers?

Loosely cover and store at room temperature or in the fridge for up to 2 days. The crust will soften over time, but it still tastes great.
