This recipe for the Best Oatmeal Pie is Grandma's prized blue ribbon winning recipe. Like a pecan pie but with oatmeal!
THE BEST OATMEAL PIE RECIPE
I compare this oatmeal pie to pecan pie. It tastes just like a Pecan Pie but without the pecans. So, if you have someone in your family that isn't a fan of pecans, then this might just be the pie to make. Oatmeal pie was developed in a time when either pecans were hard to come by or were too expensive.

FREQUENTLY ASK QUESTIONS:
It's a thinner, smaller oatmeal than the old-fashioned oatmeal and it is easier to eat and chew in recipes like this.
Feel free to MAKE YOUR OWN PIE CRUST or a pre-made frozen pie crust that has been thawed.
Dark brown sugar can be used in place of light brown sugar. It just has a tad more molasses in it so it will have a richer flavor. But don't use all granulated white sugar. It won't turn out the same.
I don't bake with sugar substitutes so I can't say for sure. It seems like it would work. If you are familiar with baking with sugar substitutes then follow the instructions you would normally use for substituting.
Sorry, I don't have a good substitute for you there.
Store leftovers (covered) in the refrigerator for 3 days. This pie can be frozen. Cover pie very well or store in an airtight container so that it doesn't get freezer burned and it will stay good for up to 3 months.

If you make the pie and freeze it, what is the best way and times for reheating it? Thanks!
Jack
Great recipe. Very delicious and easy to make. I added some golden raisins and it worked fine. Its hard to stop at just one slice.
RACHAEL JOHNSON
So I loved this pie made it for Thanksgiving yesterday but my pie looked like oats it didn't look like yours and the oats were a bit chewy on the top. OK so im writing this qnd I just realized I used old fashioned oats hahaha. Nvm..but either way the taste was amazing and I will be making this again probably every year. My son has a peanut allergy and it's hard to find safe pecans so this substitute was amazing. Thanks again!!!!
Chris
Would I be able to use normal rolled oats instead of quick? Thanks
Pat
Does this pie freeze well?
Brandie @ The Country Cook
Hi Pat - yes you can. Just wrap it very well and it can be frozen for up to 3 months.
Peg
Could I use honey instead of corn syrup?
I want to make it right now. Lol

My family has a very similar recipe that we’ve been making for 40+ years, called Poor Man’s Pie. My daddy didn’t like pecan pie, I don’t either, so we do this one instead. We use Golden Eagle syrup, which is made here in my home state of Alabama, and it is absolutely to die for!!!! My 7 year old daughter loves it to!
Alli
Made this recipe today and it is so so good. I couldn’t stop at one slice. This is my new go-to pie! Love it, thanks for sharing.
