If you’re like my family, you probably have some leftover pie after a big holiday meal. Or maybe you don’t because Uncle Joe got up at 2am, cleared the place out, and then blamed it on Scruffy! Poor Scruffy.
The next morning, no one really has the nerve to make the first move on the leftover pie. Some might declare, “Oh I simply couldn’t imagine eating pie right now!” grasping their stomach in embarrassment. Others nod in agreement, secretly wishing they would leave the room so they could have a slice for breakfast.
After my pumpkin pie testing, I was left with a lot of pie. Eric brought a bunch to work last week (frozen, so it wouldn’t turn to mush during his commute), but I was left with almost a full pie calling my name from the fridge. Having a pie in the fridge for no reason is like listening to an annoying, loud ticking clock; it can drive a person crazy after a while! Instead of picking away at it over the course of the week, I thought it would be fun to take the leftover pie and repurpose it into another recipe.
A recipe I could rationally eat for breakfast and not feel like a crazy person…

Pumpkin Pie in a brunch recipe sounds pretty crazy though, doesn’t it? I know, I know, but trust me on this one. The recipe didn’t turn out super sweet or overpowering for a morning meal. Because I didn’t make my pie filling super sweet, it actually works really well in a baked oatmeal recipe. It’s fluffy and super creamy thanks to the pumpkin filling interspersed throughout. My favourite part is getting a big hunk of pie and crust in the same gooey bite. It’s heaven! And it’s why this makes the perfect holiday brunch recipe.
Here’s how to turn your leftover pie into a brunch recipe your whole family can enjoy….might I say, it’s really easy as pie.
Grab your leftover pie and chop it up to make about two and a half cups. Your family will probably wonder if you’ve gone crazy, but just ignore them! They will see the light soon.

Bite-sized pie is fun…real fun.

I had a feeling that this would be a killer holiday brunch recipe and a great way to use up pie. Bonus points for you if you use my Vegan Pumpkin Pie with a Sweet and Salty Pecan Crust as that’s the version I used. I can hardly contain myself around it. The pecan crust was to die for in this breakfast casserole. Of course, you could use any flavour of pie you want. Apple pie would be really good too!
I mixed up my oatmeal ingredients: rolled oats, almond milk, ground flax, vanilla, spices, maple syrup, and baking powder. Just basic oatmeal stuff!

and then I stirred in my chopped pumpkin pie to make it all chunky and wonderful…

I spread it into a greased casserole dish and then crumbled a bit of pie on top for a “streusel”.

Bake for 30 mins. at 375F.
And just like that, you have a drool-worthy pumpkin pie breakfast casserole to share with the entire family!

Or hide it from your family. Yes, you might want to hide it.

Pumpkin Pie Holiday Breakfast Casserole
This is such a fun holiday breakfast that could become a tradition each year! You’d think it would be crazy sweet, but it’s really not. The pumpkin pie is quite spread out so it doesn’t overwhelm, but it’s present enough to taste like you are eating pumpkin pie in breakfast form. Serve with a drizzle of maple syrup and almond milk or some whipped coconut cream to garnish.
Yield: 6 servings
Ingredients:
- 2 cups rolled oats
- 3 tbsp ground flax (or chia seeds)
- 1.5 tsp ground cinnamon
- 1/2 tsp nutmeg
- 1/2 tsp ground ginger
- 1/2 tsp kosher salt
- 1/2 tsp baking powder
- 2 cups almond milk (or other non-dairy milk)
- 2 tsp pure vanilla extract
- 1/4 cup maple syrup, or to taste
- 2.5 cups leftover chopped pumpkin pie (or other flavour) approx 3-4 slices, divided
1. Preheat oven to 375F. Chop 3-4 slices of leftover pie to make 2.5 cups of chopped pie.
2. In a large bowl, mix together the dry ingredients. Now add the wet ingredients and stir well. Adjust sweetener to taste. Fold in 2 cups chopped pie gently. Crumble remaining 1/2 cup of pie on top for a “streusel”.
3. Pour into a greased casserole dish and bake at 375F for 30 minutes or so.
4. Serve with a drizzle of maple syrup and almond milk. Add a dollop of whipped coconut cream to garnish if desired.

I won’t tell you how crazy good this was. Or even how good it was the next morning eaten cold. Or how good this was as a post-run snack.

I just had a cool idea for this recipe…it would probably be good if you stirred in some leftover canned pumpkin right into the oats before baking! *dies* why did I not think of this earlier? I have pumpkin to use up too. If you are going to stir in some canned pumpkin I would add about half a cup and then adjust the sweetness as desired since the pumpkin will make it a bit less sweet. Please let me know if you try that out!
By the way, I’ve created a page just for my vegan Thanksgiving recipes…you can check it out here. Have a happy, safe, and delicious Thanksgiving to my American readers!
Be sure to check back this week…I have some surprises up my sleeve!
This is genius, Angela. I love that you’ve managed to incorporate pie into a healthy breakfast casserole.
And that conversation about not being able to eat pie the morning after Thanksgiving? Yep, that’s totally my family. My mom and I end up just taking bites throughout the day, since small bites obviously don’t count. ;)
do we think this would work with apple pie :)
Yup :)
What a brilliant idea, Angela. I love the way you embrace next-day sweets rather than obsessing over them and feeling “guilty.” Just eat wholesome treats for breakfast! Divine!
I’m going to have to make extra pumpkin pie so I can try this! It looks delicious!
Brilliant as always. I feel my oatmeal always contains everything except the kitchen sink.
I’m already starting to feel pumpkined out. I didn’t think it was possible?!
I am literally reading this while eating pumpkin baked oatmeal, wishing I had some pie to crumble over it. I have to wait until tomorrow for pie… but you can bet this will be happening Friday morning with more pumpkin baked oats! :)
I’m definitely doing this with apple pie! Not a huge pumpkin pie fan (but love pumpkin everything else, go figure) but I bet apple pie would be just as good :)
What a cool idea! I would love love to try this….if there is any leftover pie…which is never around my family! Haha :)
Me too, Lauren! There is never any pie left after one of my family’s gatherings! :)
Delicious! Now how to incorporate pie into a lunch dish to eat it all day long?
What an incredible idea! I see no problem in having desserts for breakfast every now and again, no worse than a donut right?
Yum! Brilliant way to use those leftovers!
So now I really do need to make all 3 of the pies you posted the other day because I have to make the casserole too!! Today is another one of those “I need breakfast round 2” sort of days. I’m bookmarking this one Ange!
YUM! This sounds delicious as I too have been a little obsessed with pumpkin this year! Can’t wait to try this over the weekend with the leftovers!
This looks delicious! Great way to use up leftover pie! I hope you are having a wonderful week!
Genius! I love these ideas :) Who says you can’t have pie for breakfast!?
this is genius! although i would not hesitate to just go straight for the pie for breakfast, this would make me feel a little more healthy :)
What a great idea! I think I’d mash up some sweet potatoes at the bottom to give it another layer :)
Genius. Seriously. I may have to hide a few slices of pie tomorrow for this purpose…
Hi Angela!
I just wanted to take an opportunity to say that I love your blog! I use lots of your recipes in my own (hyveehealthstateofmind.wordpress.com) – I am a dietitian at a midwest based grocery store (don’t worry, I always link back to you). Thanks for all the great recipes!!!
Fortunately, I have no problems eating pie the next day for breakfast. But I prefer apple in the morning. . . ;)
Fiber from the oatmeal helping to slow down the sugar spike- genius! I think I would prefer that over the pie. ;)
I wish I had pie now to make this! Unfortunately my family loves pumpkin pie so much there’s hardly any leftovers. Of course I could bake an extra one just for this purpose… :)
This is seriously genius. YOU are seriously genius!
Angela, I was really wanting to make your recipe for vegan gravy to take to my family Thanksgiving dinner this weekend, and was wondering, is there anything I can sub for the tamari? Thanks in advance!
Any type of soy sauce should work! Shoyu, liquid aminos, whatever you’ve got.
Thank you Emily!
I’m eating a boring bowl of oatmeal right now wishing for some pumpking pie pieces in it!
What a great idea! I’ll have to make two pies next time to make sure there is something left over for breakfast.
I always think of last minute things I should have done when I’m posting the recipe! I just love those pretty white plates. And the casserole…no words.
confession: my family and I eat pie for breakfast the day after thanksgiving EVERY year….SO GOOD. but this is such a cool new way to mix it up and get our pie fix!
haha I love that!
Two words: PURE. GENIUS.
Great idea! I melt mine down and make it into a custard for pumpkin bread pudding! I love the oats!!!
what is this thing called ‘leftover’ pumpkin pie LOL ;) I’ve never seen it!
I’m going to make this with some pumpkin cookies that are too dry for my taste!
Wow, that looks incredible! I don’t even want to eat my pumpkin pie…I think I may just bake it, let it cool, and then chop it up to make this casserole! Happy Thanksgiving :)
that would definitely be a good idea!
I love the crumbly streusel topping idea! Yum. What a resoureful way to use up leftover pie hehe! Love from England.xo http://hannahalehandra.blogspot.com/
Absolutely genius!!!
wow…I was just discussing what to do with leftover pumpkin pie and then I saw this!!! (mouth watering) Thank you!!! I will definatly try this!!
I love pumpkin oats, but they sounds even better with chunks of pie crust!
I have to admit: when I saw the title I was thinking it might be a really heavy, sugar-y casserole, but I kept reading anyway. Now…now I wish I had some pumpkin pie to make this!! I LOVE baked oatmeal, and this is a great idea!! I may have to make pumpkin pie sometime soon just for this :D and also because I’m DYING to try your pecan crust!
Oh, yeah! Pumpkin pie anytime is great but I love this idea for breakfast so it seems like you’re not really being bad!
This is brilliant!!
“I was left with almost a full pie calling my name from the fridge. Having a pie in the fridge for no reason is like listening to an annoying, loud ticking clock; it can drive a person crazy after a while! Instead of picking away at it over the course of the week”
That is exactly what happens to me! Now I have a way to use it up :D
Um, this is BEYOND brilliant! I can eat pumpkin pie any time… that is if the rest of my family doesn’t get to it first!
completely brilliant! It makes pie for breakfast a perfectly acceptable idea when you throw some oatmeal into the mix- healthy! I wonder how throwing a piece into the blender for a smoothie would turn out!!
How creative! Looks scrumptious!
best idea ever!
Wow!! I might have to bake a pie now! That looks amazing!
OMG, seriously….I’m going to gain 24 lbs from now until boxing day….this is so friggin FAB! Where have you been all my life????
I need to make pumpkin pie, then hide it from myself just so I can take a couple pieces for this breakkie!!!!!!! YUM!
xxoo
That looks naughty. :)
My list of recipes to make when i get home from uni keeps getting longer and longer :)
Angela, you are one heck of a recipe-making genius!
Aaand just when you think it can’t possibly get any better…
it does.
I think I am going to try this with the leftover pecan pie that has been sitting in my fridge since our Canadian Thanksgiving!
Oops, in my freezer. Not sure I would want to eat pie that had been in my fridge that long!
