Step‑by‑Step Instructions for Rhubarb Blueberry Galette
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This temperature ensures that your rhubarb blueberry galette will bake evenly, producing a beautifully golden crust. While the oven warms, line a baking sheet with parchment paper or a silicone baking mat to catch any drips during baking.
Step 2: Prepare the Filling
In a large mixing bowl, combine the chopped rhubarb, blueberries, granulated sugar, corn starch, and your choice of cardamom or cinnamon. Gently stir the mixture until the fruits are well-coated and the sugar starts to dissolve, about 2–3 minutes. The vibrant colors will give you a delicious glimpse of the tangy-sweet filling that awaits!
Step 3: Roll Out the Crust
Next, take your pie crust and roll it out on a lightly floured surface until it reaches about 12 inches in diameter. Aim for a slightly thicker edge to help hold the filling. Carefully transfer the rolled crust to your parchment-lined baking sheet, ensuring it is centered and ready for the fruity filling.
Step 4: Add the Fruit Mixture
Spoon the prepared fruit filling into the center of the rolled-out pie crust. Be sure to leave a generous 1½-inch border around the edges, as it will be folded over later. Arrange the fruits evenly for a balanced presentation and a delightful bite, setting the stage for your rustic rhubarb blueberry galette.
Step 5: Fold the Crust Edges
Now, gently fold the crust edges over the filling, creating pleats as you go. This rustic technique adds charm and helps to keep the filling secure during baking. Brush the edges with the beaten egg for a perfect golden hue, and if desired, sprinkle a pinch of cinnamon sugar or demerara sugar on top for extra sweetness.
Step 6: Bake to Perfection
Place the assembled galette in the preheated oven and bake for 40 minutes. Keep an eye on it as it bakes; it’s done when the crust is deeply golden and the filling is bubbling joyfully. This step is crucial for achieving that signature rustic look while ensuring the flavors meld beautifully.
Step 7: Cool and Serve
Once out of the oven, let your rhubarb blueberry galette cool on the baking sheet for about 10 minutes. This cooling period allows the juices to settle, making slicing easier. Afterward, serve it warm on its own or with a scoop of vanilla ice cream for an indulgent treat that everyone will love.

How to Store and Freeze Rhubarb Blueberry Galette
Fridge: Allow the galette to cool completely before wrapping it in plastic wrap or aluminum foil. It can be stored in the refrigerator for up to 5 days without losing its delightful flavors.
Freezer: To freeze, slice the galette and wrap each piece tightly in plastic wrap, then store in an airtight container or freezer bag. It will stay fresh for up to 3 months.
Reheating: For best results, reheat slices in a preheated oven at 350°F (175°C) for 10-15 minutes or until warmed through. This will restore the crust’s crispiness, bringing back that fresh-baked taste.
Serving Suggestions: After reheating, serve your galette with a scoop of vanilla ice cream or a dollop of whipped cream for an extra special treat!
