Ingredients

Filling

  • ¾ pound rhubarb, chopped (about 3 cups)
  • 1 cup blueberries
  • ¾ cup granulated sugar
  • 1 tablespoon corn starch
  • ½ teaspoon cardamom

Crust and Topping

  • 1 pie crust (store-bought or homemade)
  • 1 egg, beaten
  • Pinch of cinnamon sugar or demerara sugar

Instructions

  1. Preheat Oven: Preheat your oven to 400 degrees Fahrenheit to prepare for baking the galette.
  2. Prepare Filling: In a mixing bowl, combine the chopped rhubarb, blueberries, granulated sugar, corn starch, and cardamom. Stir well to evenly coat the fruit and thicken the filling.
  3. Prepare Crust: Roll out your pie dough on a piece of parchment paper placed on a baking sheet. If using pre-made dough, spread it out evenly.
  4. Assemble Galette: Spoon the rhubarb and blueberry filling onto the center of the pie crust, leaving approximately a 1 ½ inch border free of filling around the edges.
  5. Fold Edges: Carefully fold the edges of the pie crust up over the filling in pleats to create a rustic border. This helps contain the filling during baking.
  6. Egg Wash and Sugar: Brush the folded crust edges with the beaten egg to give it a golden shine once baked. Sprinkle a pinch of cinnamon sugar or demerara sugar over the crust edges for added sweetness and crunch.
  7. Bake: Place the baking sheet in the oven and bake for 40 minutes or until the crust is golden brown and the filling is bubbly.
  8. Cool and Serve: Remove from oven and allow the galette to cool on the baking sheet for about 10 minutes before slicing and serving. This cooling helps the filling set properly.

Notes

  • You can use store-bought pie crust to save time or make your own for a fresher flavor.
  • Adjust the sugar level based on the tartness of your rhubarb and personal preference.
  • Cardamom adds warm spice but can be omitted or replaced with cinnamon if desired.
  • Serve galette warm, optionally with whipped cream or vanilla ice cream.
  • Ensure the edges are well sealed to prevent filling from leaking during baking.
