Oatmeal Pie

Oatmeal Pie is an old-fashioned favorite with a delicious brown sugar flavor, a chewy layer of oatmeal, and flaky pastry! 

While we love pie classics like Chocolate Cream Pie or Key Lime Pie, we have a new-found love for this unique Oatmeal Pie recipe that is similar to Pecan Pie.

Pecan Pie’s Cousin

If you love Pecan Pie, you definitely need to try this Oatmeal Pie. It has the same gooey, brown sugar, caramel flavor – but instead of crunchy pecans on top, there’s a layer of chewy oatmeal.

Oatmeal Pie is also called Amish Oatmeal Pie, and I’ve read that it was made in the South during the Civil War as a substitute for Pecan Pie. It was a new pie recipe to me until recently, but I will definitely be making it again and again because it’s just THAT good!

This Oatmeal Pie tastes delicious with a scoop of Vanilla Ice Cream on top or with Whipped Cream. It’s a perfect addition during the holidays to your classic Pumpkin Pie or Apple Pie.

It might not be a very common or typical pie recipe, but I assure you, those who try it will be pleasantly surprised. It’s delicious!

How to Make Oatmeal Pie

Oatmeal Pie is actually super easy to make. The filling comes together in under 10 minutes, but to save even more time use store-bought pie crust. If you’re up for it though, I recommend our Homemade Pie Crust recipe!

PREP. Preheat the oven to 350°F.

CRUST. On a floured surface, roll out the pie crust into a circle about 12 inches in diameter. Transfer the pie dough to a 9-inch glass or ceramic pie plate. Fold over the and crimp.

Lightly dust the pie dough with flour then place it in the fridge as you make the filling.

DRY INGREDIENTS. In a medium bowl stir together the brown sugar, cornstarch, cinnamon, and salt to ensure no lumps in the brown sugar.

WET INGREDIENTS. In a separate large bowl, whisk the eggs. Whisk the sugar mixture, corn syrup, melted butter, and vanilla extract into the eggs until combined. Stir in the oats.

BAKE. Pour the batter into the pie crust. Bake the pie for 45-55 minutes or until the top is set and the middle no longer wobbles when given a nudge.

Remove from the oven and cool fully before serving.

Recipe Tips

Brown crust. The pie will bake for about 45 minutes – but check it at 30 minutes to see if the crust is browning too much. If the crust is already golden, add a pie shield or aluminum foil around the edges of the pie to prevent the crust from burning.

Oats. I use quick oats for this recipe because they cook up chewy and delicious as the pie bakes. Do NOT use steel-cut oats, they will be hard and crunchy. Instant oats are also a no-no because they will behave like flour and create a gooey and chewy layer on top.

Cool the pie fully (at least 4 hours) before slicing to avoid a gooey mess. The filling will set as the pie cools. To serve the pie warm, heat the slices individually in the microwave.

Cracks in the pie. Many types of pies can crack on top during the baking process. One reason this happens is that the top layer gets overbaked causing it to dry out a bit and crack.

To help avoid this, bake the pie on the lower rack in your oven. Not only will it help keep the top of the pie from cracking, but it will help ensure that the crust is baked all the way through. If the crust does crack, simply cover it with well-paced dollops of Whipped Cream.

Serving suggestions

Of course, I prefer serving Oatmeal Pie with a big old scoop of Vanilla Ice Cream on top, but there are other toppings you could try!

Storing Info

Make ahead of time. Oatmeal Pie can be made ahead of time, which is great for the holidays. Cover and store in the fridge for up to 3 days.

FREEZE the pie by covering tightly and placing it in a freezer-safe bag for up to 2 months.

    Oh my, this is incredibly gooey & good!! By the title, I was unsure what I’d think, but I will definitely make this again.

    I’m not a “bowl of oatmeal” fan so I wasn’t sure about as a pie, but I have to say it was so good. It’s also an easy recipe to make, especially if you use a premade pie crust.

  3. How can I fix a dry oatmeal filling after it bakes? I had to substitute maple syrup for Keri (stores didn’t have any) my pie filling is dry. Can it be fixed before I est it?

    1. You know, I’m not totally sure. I haven’t ever used maple syrup for this recipe. The texture of maple syrup is quite different than corn syrup, so I imagine that had something to do with it being dry. I’d probably suggest trying again or just serving with a generous amount of whipped cream or ice cream. 😉
