It is rare for a pie crust recipe to contain no fat. However, some pie crust recipes that use as little as 1 to 2.5 grams of fat include FOOD.com's fat-free pie crust and Yummly.com's calamondin or lemon pie's oatmeal cookie crust.
To make FOOD.com's fat-free pie crust, preheat the oven to 475 degrees Fahrenheit. Then, mix together 1 cup of all-purpose flour, 4 tablespoons of fat-free margarine, 3 tablespoons of cold water and 3/4 teaspoons of Morton Lite Salt with a fork until ingredients are well-combined. Roll this mixture into a ball and place it between two pieces of flour-dusted wax paper. Next, flatten the ball into a circle and arrange in a pie-pan that has been sprayed with nonfat cooking spray. Cut off the excess crust at the edges, prick the bottom with a fork and brush with a layer of beaten egg whites before baking in the oven for 10 minutes.
To make Yummly.com's fat-free oatmeal cookie pie crust, preheat the oven to 375 degrees. Then, blend together a 1/2 cup of quick oats, a 1/2 cup of sorghum flour, a 1/4 teaspoon of baking soda, salt, vanilla and brown sugar, and 2 tablespoons of natural sugar. Transfer this mixture into a bowl and add a 1/4 cup of apple sauce, then mix. Flatten mixture into an oiled pie pan and then bake for eight minutes.
