Blueberry Galette

An easy rustic Blueberry Galette made with a buttery pastry and filled with plump blueberries, a hint of lemon and vanilla. This recipe is make ahead ready and goes from freezer to oven with ease! Top with your favorite vanilla bean ice cream. This galette is vegetarian, easily egg free.
This recipe may be made with one store bought pastry crust (pie dough). However for homemade, which I recommend, see my DIY Buttery Pie Crust for more tips on how to make the flakiest and tastiest homemade pie dough!
Make Ahead Tips: The pastry can be made and refrigerated two days in advance or frozen for up to two weeks in advance. The assembled galette can go straight from freezer to oven.
This recipe makes one 9" galette.

Ingredients

For the Pastry (11-12 oz / 311g -340g):

  • 1/2 C (114g) Unsalted Butter straight from the fridge
  • 3 Tbs Milk plant or dairy
  • 1 1/2 tsp Apple Cider Vinegar
  • 1 1/4 C (190g) All Purpose Flour
  • 1 Tbs Cane Sugar
  • 1/2 tsp Fine Sea Salt

For the Galette:

  • 1/2 C (110g) Cane Sugar
  • 2 Tbs Corn Starch
  • 1/4 tsp Fine Sea Salt
  • 3 C (455g) Fresh Blueberries about 1 1/2 - 2 pints of blueberries
  • 1-2 Tbs Lemon Zest Use 2 Tbs for an extra lemony boost, about 2 lemons
  • 1 1/2 Tbs Fresh Lemon Juice from about 1 lemon
  • 1 tsp Vanilla Extract
  • 1 Egg for egg wash or use milk or nut milk for egg free

Instructions

To Make The Pastry:

  • Cut the cold butter into 1/4" (6mm) square pieces. Place the butter in the freezer for at least five minutes.
  • Whisk the milk and apple cider vinegar together until it bubbles. It will thicken as it sets for five minutes. This is your buttermilk.
  • In a large bowl, mix the flour, sugar and salt. Using your hands (or a pastry cutter), cut in the butter by pinching/flattening the butter as you toss it with the flour. The butter should remain in larger chunks, such as almond size. Work quickly to keep the butter cold.
  • Pour in the milk mixture. Use your hands to incorporate the buttermilk, folding and pressing the mixture. Flattening out the butter is okay. To test hydration, grab a hand full of dough and squeeze it. If it holds together, it's ready for further shaping without adding more liquid. If it's still crumbly or falls apart, add a splash of milk or cold water and continue folding and pressing to a shaggy consistency. If the butter is starting to get a bit warm at this point, put the mixture in the freezer for about 5 minutes. We want the dough to stay as cold as possible.
  • On a lightly floured work surface, dump out the shaggy dough. Using a bench scraper, fold and press the dough at least 6-8 times, eventually shaping the mixture into a rough rectangle. Use the heel of your hand to press and schmear the dough onto the work surface. Gather the dough once again using the bench scraper and shape into a rectangle. Fold and press the dough over and on top of its self 7-8 more times. This helps to hydrate the dough and build flaky layers.
  • Gather all the bits together and shape into a rough disk approximately 1/2" (12mm) thick. Wrap tightly in parchment paper and rest in refrigerator for at least and hour, but preferably two if you can.
    MAKE AHEAD TIP: at this point the dough may be rested in the fridge for up to two days or frozen for up to two weeks. Wrap snugly in parchment, then refrigerate or freeze in a lidded container or freezer bag.

For the Blueberry Filling:

  • Place the refrigerated dough on a lightly floured work surface. Allow to set for about 30 minutes to soften as to make it more pliable to roll out. Set aside.
  • While the dough is resting, in a small mixing bowl, mix the sugar, salt and corn starch. Set aside.
    In a large mixing bowl, add the blueberries, sugar mixture, lemon zest and juice and vanilla. Toss to coat the blueberries (you can use a spatula here, but be gentle as to not squash the blueberries ). Set aside.

Roll Out The Pastry and Assemble:

  • Dust the top of the pastry with flour and dust your rolling pin.
    Roll the dough to 1/8" (3mm) thick to about 13 1/2" - 14" round, flouring the work surface as needed to prevent sticking. Transfer the dough to a parchment lined sheet pan.
    Mound the blueberry mixture evenly in the center of the pastry leaving about 2" (5cm) boarder.
    Fold edges over the blueberries, overlapping and pleating the edges all the way around leaving the center open.
  • Freeze the galette for at least 20 minutes while the oven preheats to 375F (190C).
    MAKE AHEAD TIP: The assembled galette can be frozen solid at this point. Simply allow it to freeze then wrap snugly in parchment and foil. Freeze for up to two weeks. When ready to bake, bake on a parchment lined sheet pan as indicated below.

To Bake:

  • Arrange a baking rack in the center of the oven and preheat the oven to 375F (190C).
  • Just before baking, whisk the egg with 1 Tbs water and egg wash the crust. Alternatively, use milk or nut milk here (with no additional water) for egg free. Optionally sprinkle the pastry with turbinado or raw sugar to finish the crust.
  • Bake the galette for 45-50 minutes until the center is bubbly and the pastry is golden (same for a frozen galette). Rest the galette at room temperature for at least 20 minutes before slicing. Serve with vanilla bean ice cream.

To Store:

  • The baked galette can be stored at room temperature for up to two days. For longer storage, wrap snugly in parchment and foil, then into a freezer bag for a few weeks. Reheat at 350F for about 15 minutes

Notes

*Fat, butter in this case, is an essential component of pastry. It plays an important role in flavor and texture. I use European style or Organic Unsalted Butter.
A note on buttermilk: I make my own in this recipe using milk and apple cider vinegar. If you use store bought buttermilk, due to the difference in moisture content of real and homemade buttermilk, you may need to add a bit more real buttermilk to your dough. Add only 1 tsp at a time until tough is hydrated enough.
