Add scoops of cold butter to the bowl, one tablespoon at a time.
Use your hands to fully combine the butter with the flour and salt.
Add cold water slowly and continue to combine with your hands until a dough forms.
Place the dough on a floured surface or piece of parchment paper and shape it into a disk.
Wrap the dough disk in plastic wrap and place it in the refrigerator to chill for at least a half-hour.
Prepare the filling
Heat oil in a large pan over medium heat.
When the oil is hot, add the shallots and saute for 5 minutes, making sure to stir often to avoid burning.
Add the garlic and cook for an additional 3 minutes, stirring often.
Add the mushrooms, thyme, and salt and cook for 12 minutes, until the mushrooms soften.
In the meantime, add all of the cashew cream ingredients to a blender and blend until smooth. Set aside.
Add the tomatoes and artichokes and cook for an additional 8 minutes, until the tomatoes soften.
Mix in the spinach and then turn off the heat. Allow the mixture to cool with the lid on for a couple of minutes until the spinach is fully wilted.
Assemble the galette
Roll out your dough on a floured surface until the dough is about ¼-⅛" thick. You can trim any uneven edges at this point if you’d like.
Spread the cashew cream evenly on the dough, leaving about 1 ½ - 2" of crust.
Add the veggie mix on top of the cream.
Fold the crust over the toppings, overlapping wherever necessary.
Lightly brush the crust with butter or a neutral oil.
Bake
Bake at 375°F for 45-55 minutes.
Enjoy!
Notes
Cashew Cream. Feel free to make it a day in advance to save some time. Allowing it to sit in the refrigerator for a couple of hours (or overnight) will provide more time for the flavors to meld, making it taste that much better! Sometimes when making cashew cream, I will add a tablespoon or two of coconut milk to it to make it more creamy and smooth.
