Ingredients
Method
Make the crust
- In a large bowl, toss together the flour, sugar, and salt. Cut in the cold butter with a pastry cutter until pea sized crumbs form and flour is slightly moistened. Using a rubber spatula, stir in the cold water until a shaggy dough forms. Do this one Tablespoon at a time, as the amount of water will vary depending on weather, climate, and time of year. The dough shouldn't be crumbly or sticky , but soft and shaggy with patches of butter. I usually do about 6-7 Tablespoons.
- Dump the shaggy dough onto a floured surface and form it into a ball. You don't want to knead it, just shape it into a ball. Then, flatten it slightly with your hands into a thick disk and wrap tightly with cling wrap. Chill the covered dough for at least 2 hours, or overnight.
Make the galette
- Preheat the oven to 425℉ and line a large baking sheet with parchment paper.
- Remove the dough from the fridge and peel off the cling wrap. Roll the dough out into a 12x14 inch oval on a lightly floured surface. The shape doesn't matter, mine just usually ends up being an oval. Transfer this rolled out dough onto the previously prepared baking sheet.
- Spread the Nutella in an even layer over the dough, leaving an inch wide border along the sides. Sprinkle the chopped chocolate on top of the Nutella, and then place the bananas on top of that in an even layer. Fold the edges of the galette over to create a crust. Try not to cover the bananas when doing this.
- In a small bowl, whisk the egg with the milk. Using a pastry brush, paint the egg wash over the crust and sprinkle on some turbinado sugar. Sprinkle more turbinado over the banana slices so they will get caramelized in the oven.
- Bake for 20-25 minutes or until the crust is golden brown. This time will vary depending on your oven. Let the galette cool for 10 minutes before sprinkling on lots of flaky sea salt and serving.
- Galette stays fresh sealed in an airtight container in the refrigerator for up to 3 days. To reheat it, place it on a parchment lined baking sheet and bake at 350℉ for 5-10 minutes or until chocolate is melty again
Notes
Water: The amount of water you need will vary. In warmer months you may need a little less, and a little more in colder months. Just add water a few Tablespoons at a time until a dough forms.
