This sweet and gooey old fashioned Oatmeal Pie is exactly what your holiday table is missing! This pie has the best ever caramel like filling, it’s a cheaper alternative to Pecan pie, and a great nut-free alternative.

If you haven’t made Oatmeal pie before, you are going to be amazed at how easy it is. Oatmeal pie is very similar to Pecan pie, except it contains no pecans. Actually, it contains no nuts at all! 

Some think that this recipe originates from the Amish community, while others state that the oatmeal pie recipe was created in the South during the Civil War, due to pecans being expensive or hard to find at that time. 

This pie will be delicious for Thanksgiving, Christmas, or any time when a gooey, sweet, and caramelly pie will be enjoyed. I love this pie on a plate next to a slice of homemade pumpkin cheesecake, carrot pie, or apple pie.

Oatmeal pie is made with simple, common ingredients, and flavored with warm vanilla and cinnamon. The smells in your kitchen while oatmeal pie is baking can’t be beat.

Why You’ll Love this Pie

  1. Super Easy: Mix everything up in a large bowl, pour into a prepared pie crust, and bake. That’s it!
  2. Allergy Friendly: This is a great nut-free alternative to pecan pie. It’s dairy free as well, and can be made gluten free with some creative substitutions. 
  3. The Texture: This pie is like nothing you’ve had before. It’s creamy, caramelly, and goey with a bit of crispy oats on top. Delicious! 

Ingredients Needed

I love recipes like this one, where all of the ingredients are already in my kitchen!

Ingredients needed to make oatmeal pie filling including oats, karo, eggs, butter, brown sugar, cinnamon, vanilla, flour, and salt.
  • Single Pie Crust: Make a homemade pie crust, or buy a premade, pre-shaped one to save time. Refrigerated rolled pie crust, like from Pillsbury will work too.
  • Brown Sugar: Light brown sugar adds flavor and tons of sugary sweetness to the pie. Dark brown sugar can be used as well to give additional molasses flavor.
  • Eggs: Put your eggs out so that they come to room temperature. This will help them to incorporate into the filling more evenly than if they were cold. Eggs hold this pie filling together. 
  • Flour: This helps to thicken up the filling. 
  • Vanilla Extract, cinnamon, and salt: These three work together to flavor this simple oatmeal pie. 
  • Corn Syrup: To create an ooey gooey texture, corn syrup is what you want! I use Karo corn syrup. 
  • Butter: Each ingredient we add just makes this pie filling more and more delicious.
  • Quick Oats: We use quick oats because we aren’t cooking them ahead of time, and they are thinly rolled and will absorb the liquid from the filling best.

Tip!

Add Raisins to get the effect of an oatmeal raisin cookie, but in pie form!

How to Make Oatmeal Pie

  1. Prep Pie Crust: If you’re using a homemade crust recipe or a rolled pie crust, place it into a 9-inch pie plate (this is the pie dish I’m using in the images, I love it!). Pinch and crimp the edges. If you bought a pre-shaped frozen crust, then it’s ready to go.

  1. Mix: In a large bowl, combine all of the filling ingredients, and whisk until combined. Pour the filling into the pie crust. 
  2. Bake: Bake in the center of a preheated oven for 50-60 minutes. The filling should be only slightly jiggly in the center. 
  3. Cool: Allow the pie to cool and rest for at least two hours before serving. 
  4. Serve: A scoop of vanilla ice cream or a dollop of whipped cream will take this pie to the next level.

Recipe Tips

Let it Cool: Fair warning, if you try to cut into this pie before it’s had a chance to cool completely, you will end up with a runny mess. The pie needs time to set before serving.

Add Nuts: I know that I said that this was like a pecan pie, but without the pecans, but a handful of chopped pecans or even walnuts or almonds can be added to give some extra crunch if you like. 

Enjoy with Ice Cream: Vanilla ice cream pairs so well with this pie. It tastes like a caramel sundae with a crunchy oat topping, or an ice cream blizzard packed with caramel candy bars.

What to Serve with Oatmeal Pie

Other Pies: Sometimes a pie is great on its own, but one pie is never as good as multiple pies! Go here to see all of my pie recipes, or try making my Pumpkin Pie, Chocolate Chip Cookie Pie, Cherry Pie, or Peach Pie. 

Make it for Thanksgiving: Oatmeal pie is perfect for your Thanksgiving table. While you’re planning, check out all of my Thanksgiving recipes for turkey, sides, and desserts. 

Have it After Dinner: Pie doesn’t need to be saved for special occasions. Make this pie ahead of time and enjoy it after a nice hearty family dinner, like Slow Cooker Pork Chops with Gravy or my favorite Meatloaf recipe.

FAQs

How do I store leftover oatmeal pie?

Store leftovers, or save this pie for later by keeping it covered, in the fridge, for up to 3 days. Serve cold or warm up slices in the microwave for just a few seconds to take off the chill.

Can you freeze oatmeal pie?

Oatmeal pie will freeze really well, in case you want to make it ahead of time. It’s also a great recipe to make two of, and save one for later. Well wrapped, the pie should be good in the freezer for up to 3 months.

What kind of oats are in oatmeal pie?

We are using Quick Oats, rather than old fashioned or instant oats. This type has the perfect texture for this pie. The oats melt partially into the filling, but still crisp up on the top and edges. Use old fashioned oats to make Oatmeal Balls or Baked Oatmeal Cups instead.

    I made this with a few changes since I am diabetic. I used sugar free maple syrup instead of karo syrup. I also used Swerve brown sugar substitue. It was delicious
