Step 1

Prepare a 9-inch pie dish by greasing with olive oil.

Step 2

Blend the oats in a blender or food processor 2-3 minutes until it becomes a flour mixture.

Step 3

Transfer blended oats to a mixing bowl and stir with sugar and salt to combine.

Step 4

Make a well in the center of the mixture, add olive oil and stir until crumbly. Add 4 tablespoons of water, one tablespoon at time to the mixture, while stirring until the dough becomes slightly moist and sticky.

Step 5

The batter may still fall apart, but will stick together easily if you pinch it together. If it doesn't, add 1-2 tablespoons of water more.

Step 6

Press the dough into the prepared pie dish. Press it flat and even across the bottom and up the sides.

Step 7

You can either store the unbaked pie shell in the refrigerator in the pan until you're ready to bake a pie or bake it at 375 F for 10 minutes until golden brown. If you bake it ahead of time, you can bake a pie in it after it cools or store the pie crust in the refrigerator up to 10 days until you make a pie.
