Healthy Easy Oat Pie Crust Recipe (Vegan, Gluten Free, Refined Sugar Free)

The last time I made this Healthy and Easy Oat Pie Crust Recipe, it was to make two shallow vegan coconut cream pies (click to view recipe). I had plans to make a pumpkin-pie-with-a-twist on Thanksgiving day, so I decided to see how the crust would work a) as one not-shallow pie and b) with the pumpkin pie experiment I was developing. As it turns out, both worked great!

I thought it would be best to post the pie crust separate from the new pumpkin pie recipe (which will be next) since it goes with many types of pies. I also wanted to repost the crust recipe with updated photos and instructions for a single pie. I haven’t tried making a single non-shallow single coconut cream pie yet, but maybe I’ll do that next. Till then, I know the two-pie method yields delicious results.

Healthy Easy Oat Pie Crust Recipe (Vegan, Gluten Free, Refined Sugar Free)

This oat pie crust was a total accident. I was trying to make a healthy snack by forming this concotion into bite-sized balls. But it didn’t turn out like I wanted.

So I turned it into something else…

A healthy pie crust that is naturally:

  • Gluten-Free
  • Vegan
  • Refined-Sugar-Free

Not bad for an accident!

Healthy Easy Oat Pie Crust Recipe Ingredients

I wanted to see if I could make a crust recipe that was made of health-boosting, whole food ingredients. Turns out, these work really nicely together!

  • chia seeds – helps the crust stick together while adding nutrients, protein, fiber, and health fats
  • water – this is to help get the chia seeds nice and gel-y
  • instant oats – this is the main ingredient and serves as a healthy, gluten-free foundation for this crust
  • flaxseed meal – a lovely flour replacement
  • coconut flakes – adds an interesting texture
  • salt – for flavor haha
  • maple syrup (or sub agave syrup): a nice refined-sugar free option – the liquid helps the crust come together
  • oil of choice (avocado, safflower, canola, or other non-flavored oil) – my current fave is avocado oil as of 2022
  • hot water

All of these ingredients are naturally gluten-free, but you should check the labels of each ingredient if you need to be 100% sure.

A Note on Pre-Baking This Healthy Oat Crust

The directions below suggest baking the crust before adding any filling.

Reader Sharlene wrote in asking if she should pre-bake the crust before making the Coconut Pumpkin Pie Recipe. I tested this out on Thanksgiving 2022 by *not* pre-baking, and I thought this came out best.

So here’s my recommendation on whether you should bake the crust or not:

  • If the filling will be baked: you should *not* pre-bake this Healthy Oat Crust Recipe
  • If the filling will *not* be baked: you *should* pre-bake this Healthy Oat Crust Recipe
