Oat Pie Crust Recipe You’re Guaranteed To Love!

Who doesn’t love the easy button option when making a homemade pie, especially when you need a naturally gluten free, allergy-friendly, nut-free, or flourless pie crust in a pinch! An oatmeal crust has it all and with virtually no effort.

There’s no rolling, chilling, or even complicated baking skills required. It’s perfect for home cooks intimidated by baking, while being extremely affordable as well. If you have oatmeal on hand, you only need 5 minutes and you’re good to go. No speciality pricey ingredients required.

A pie crust made with oats works for no bake and baked pies, many of which are in my gluten-free pie recipe collection. It can be used as a gluten free graham cracker alternative or for traditional pies, such as pumpkin and apple.

If you haven’t experienced of using oats as a flourless alternative, you are in for a treat. It has a light nutty flavor that works in everything from a savory loaf of oat flour bread to chewy chocolate chip oat flour cookies. After so much success with those recipes, I figured why not work them into a magical pie crust!

I made this crust for most of my pies at Thanksgiving and they were a hit with everybody!!! This is a keeper!

Ingredient Tid Bits

  • Oats – Ideally use quick oats because they are smaller, which binds the crust together more. If you only have old-fashioned oats on hand, that is fine, but pulse them briefly in the food processor first before combining with the other ingredients. Important note: To keep the crust truly allergen-free, use certified gluten free oats.
  • Butter – To make vegan or dairy-free crust, this may be replaced with melted vegan butter sticks, such as Earth Balance, or coconut oil.
  • Cinnamon – Just a touch adds a hint of oatmeal cookie flavor.

Let’s Make This Together!

(Note: This is a step-by-step tutorial with pictures. For more specific instructions, along with ingredient amounts, see the recipe card at the bottom of the post.)

5-minute prep (easy peasy stuff)

Start with pulsing all the dry ingredients in a food processor – oatmeal, powder sugar, oat, and cinnamon. Don’t worry if you don’t have one! I include the by hand in the recipe card below.

Add the melted butter and pulse until the mixture combines evenly and clumps up. That’s it! Oatmeal crust donezo.

Press and bake

Press firmly on the bottom and up the sides of a 9-inch pie dish. If using this for a no bake filling, bake the crust fully in a 350ºF oven for 18 minutes. For fillings that need to be baked, bake for 5 minutes, fill, and then bake according to pie instructions.

What Kind Of Fillings Work Best?

I’ve tested the recipe with a baked pie, such as pumpkin, and no bake pies, such as gluten-free cheesecake, our family’s favorite gluten free key lime pie, and this legendary chocolate peanut butter pie. Fortunately, both work very well. Basically, if a pie filling could go into a graham cracker crust, this would be a good substitute.

To fill with an unbaked filling, bake for 5 minutes, fill, and then bake according to pie instructions. A pie shield may be used to protect the exposed crust while it bakes longer.

Baked fillings, such as pumpkin and apple, will cause the bottom crust to be a little softer than traditional crusts, but it will still hold up for cutting and serving. For best results, bake the pie on the lowest rack and in a metal pie plate.

Ingredients
 

Equipment

Instructions
 

  • Preheat the oven to 350ºF.
  • Place the oats, powdered sugar, cinnamon, and salt in a food processor. Pulse to combine. Add the melted butter and process until well combined and the oats clump together, about 20-30 seconds.
    2 cups quick-cooking oats, ½ cup powdered sugar, ¼ teaspoon cinnamon, ¼ teaspoon salt, ½ cup unsalted butter
  • Press firmly on the bottom and up the sides of a 9-inch pie dish. Tips: To make the crust come all the way up the sides, press evenly on the bottom to work the excess crust up the sides. Metal pans work better for crisper crusts and baked fillings. If using a glass dish, spray with nonstick cooking spray for easier releasing.
  • For a fully baked pie crust, bake for 18 minutes, or until oats are set. If the crust puffs up during baking, use a measuring cup to flatten gently immediately when it comes out of the oven. Cool completely before filling.
  • To fill with an unbaked filling, bake for 5 minutes before filling. Bake according to pie instructions, but for best results, bake the pie on the lowest oven rack.

Notes

Making Without Food Processor
Simply mix everything together in a bowl and press in the pie plate. However, the crust might fall apart a little more upon cutting because the food processor does a better job of binding the ingredients together.
