For best results, chill the shaped galette for at least 20 minutes prior to baking. This helps guarantee the tart will hold its shape and prevents the frangipane from leaking out.
- 1 and 1/2 cups (188g) all-purpose flour (spooned & leveled), plus more for work surface
- 1/4 cup (50g) granulated sugar
- 1/4 teaspoon salt
- 1/2 cup (8 Tbsp; 113g) cold unsalted butter, cubed*
- 1/4 cup (60ml) ice cold water*
- egg wash: 1 large egg beaten with 1 Tablespoon (15ml) milk
- optional: sliced almonds and coarse sugar
- 2 Tablespoons (28g) unsalted butter, softened to room temperature
- 1 large egg, at room temperature
- 1/2 cup (50g) almond flour or almond meal
- 1/4 cup (50g) granulated sugar
- 1/2 teaspoon almond extract
- 1/2 teaspoon pure vanilla extract
Blueberry Peach Filling
- 3 heaping cups peach slices (about 2–3 medium peaches)*
- 1 cup (140g) blueberries*
- 1 Tablespoon granulated sugar
- 1 Tablespoon almond flour, almond meal, or all-purpose flour
- Make the crust: Whisk the flour, sugar, and salt together in a medium bowl. Using a pastry cutter (love this one) or a couple forks, cut in the butter until the mixture resembles coarse pea-sized crumbs. Add the water and stir until the flour is moistened. Add 1 more Tablespoon of water if the dough seems dry. Turn the dough out onto a lightly floured work surface and, using your hands, work the dough into a ball. Flatten it into a thick disk. Wrap the dough disk in plastic wrap and refrigerate it for at least 1 hour and up to 3 days (or freeze up to 3 months).
- As the dough chills, prepare the frangipane: Using a handheld or stand mixer fitted with a paddle or whisk attachment, beat the frangipane ingredients in a medium bowl on medium-high speed until combined and creamy. Cover and refrigerate until step 6.
- Prepare the blueberry peach filling: Gently toss the blueberry peach filling ingredients together in a medium bowl until all the fruit is coated with almond flour and sugar. Cover and refrigerate until step 6.
- Preheat oven to 425°F (190°C). Line a large baking sheet with parchment paper or a silicone baking mat. Set aside.
- On a lightly floured work surface, roll the dough into a 12-inch circle. If desired, trim the rim of the circle to make a clean edge. Transfer dough to the prepared baking sheet. (You can also roll the dough right out onto the parchment paper or silicone baking mat that you are using to line the baking pan. If doing so, lightly flour the parchment paper or silicone baking mat. This is what I usually do.)
- Evenly spread the frangipane into the center of the dough, leaving a 3 inch edge. Spoon or arrange the peaches and blueberries on top of the frangipane. Leave any fruit juices that are at the bottom of the bowl—that could make the galette filling too soggy. Gently fold the edges of the dough over the filling, overlapping the dough as necessary. Press gently to seal the edges. Brush the crust edges with egg wash and sprinkle the crust with sliced almonds and coarse sugar, if desired.
- Refrigerate the shaped galette for at least 20 minutes and up to 8 hours. If refrigerating for longer than 1-2 hours, cover it lightly.
- Bake until the filling is bubbly and the crust is golden brown, about 35-38 minutes. Cool on the baking sheet for 10 minutes before slicing and serving. Tastes wonderful served warm with vanilla ice cream!
- Cover and store leftover galette in the refrigerator for up to 5 days.
- Make Ahead Instructions: Both the dough and frangipane can be made ahead of time and chilled in the refrigerator for up to 3 days. The dough can be frozen for up to 3 months after prepared in step 1. Allow to thaw overnight in the refrigerator before rolling out and filling.

- Peaches: I didn’t peel the peaches, but you can peel them if desired. Slices should be between 1/8 – 1/4 inch thick.
- Fresh or Frozen Fruit: Fresh fruit is best, but you can use frozen if needed. For best results, thaw the fruit first. Blot a little dry before using in the filling.
- Cold Ingredients in Dough: Make sure the butter and water are SUPER cold. Cold ingredients, as well as chilling, help the crust keep its shape.
