Tart Shell - Makes one 9-inch Tart

This is a basic tart shell to be used for sweet and savory tarts.


1 cup plus 2 Tablespoons Bob’s all purpose gluten free flour

1 teaspoon sugar (pure cane or coconut )

1/8 teaspoon sea salt

1 1/2 teaspoons xanthan gum, or Psyllium Husk

1 stick unsalted butter in chunks ( cold )

1/2 teaspoon vanilla extract mixed with 3 tablespoons ice water.


Using a mixer with a paddle attachment, or a food processor, blend the flour, salt, sugar, and Xanthin gum, ( If using gluten free flour) then work in the butter gradually, until course crumbs are formed.

Add the vanilla with just enough water for the dough to come together. ( do not over mix )

Then shape the dough into a disk. Wrap it in plastic wrap and chill for 15 minutes.


Roll the dough into a 10 inch circle and drape it over a 9 inch tart pan with a removable rim.

Work the edges with your fingers so that the dough stands about 1/4 inch above the rim, and is about 1/4 inch thick. Prick the bottom with a fork in 8-9 places.

Freeze for 20 minutes while you preheat the oven to 425.


Place the frozen tart shell on a sheet pan and bake until it’s lightly colored. ( about 15 minutes. Check after 13 minutes and prick any swollen pockets of dough with the tip of knife.


Side Note : Bobs Gluten free all purpose flour, plus 11/2 tsp. Xanthan gum, or Psyllium Husk. This addition to the flour is essential for a flaky crust.

Using parchment paper or wax paper to roll the dough on, makes it easier to flip the dough over the tart pan.

Cooks note: for a 10” Tart, add 1/3 more of all ingredients.
