Every now and then there’s a recipe that’s such a HUGE hit in our household and it becomes a staple – a dish that finds its way into our regular rotation because our family members are begging for it. This Baked Oatmeal recipe is exactly that.
It’s a super easy breakfast recipe our family LOVES for so many reasons: it’s quick to throw together on a weeknight in just a couple minutes, it’s easy to customize with whatever ingredients or add-ins you have on hand (like fresh or frozen fruit, nut butter, and spices), it keeps in the fridge for days so we can enjoy it throughout the week on all our busy mornings before work and school, and it’s SO delicious warmed up in the microwave with a splash of milk and a drizzle of maple syrup on top.
It’s a recipe we make again and again, and we know your family’s going to love it as much as ours does!
Baked oatmeal is a simple breakfast dish made by combining mashed bananas, eggs, milk and rolled oats with a few other basic ingredients to create an oatmeal dish that’s soft and moist but sliceable – perfect for a warm, baked breakfast.
The eggs not only help hold the baked oatmeal together, they also add protein to the dish, making it a stick-to-your-ribs breakfast for the whole family.
It can be prepared and baked ahead of time and stored in the fridge in an airtight container or it can be served fresh from the oven – your choice!
It’s easy to customize with different flavours like berries, apples, peanut butter and bananas, and even chocolate chips!
It can also be made vegan by replacing the eggs with more mashed bananas, applesauce, or even pureed pumpkin, and adding vegan milk instead of conventional dairy milk.
Making baked oatmeal is SO easy and it’s made even easier with a few simple tips and tricks to ensure your success!
For the best texture, use old-fashioned rolled oats. Quick oats will work in this recipe, but they can soak up a little too much moisture and it’s possible that your oatmeal bake will end up a little on the mushy side. We don’t recommend steel-cut oats for this recipe as they’re too tough and hardy.
Make sure there are no large chunks of banana. The banana is the ingredient that sweetens the dish so it’s important that it’s distributed well throughout the mixture.
Adding eggs helps the baked oatmeal hold together as it bakes, so be sure to add the eggs OR add applesauce in place of the eggs for added moisture.
Adding cinnamon and vanilla really adds a lot of flavour to this recipe, so be sure not to skip it.
Baked oatmeal just isn’t the same without added berries or other fruit for added texture and flavour. Feel free to experiment with a variety of add-ins like apples, peaches, pears, or sliced bananas, and consider adding nuts, chocolate chips, or dried fruits for extra flavour and texture.
To ensure your baked oatmeal doesn’t stick and is easy to serve, make sure to grease your baking pan thoroughly.
If you’re short on time in the mornings, mix the ingredients and bake the oatmeal the night before, storing it in the fridge. In the morning, simply portion it out and reheat before serving.
Bake your oatmeal covered for the first 20 minutes and then uncovered for the last 10. This will give it a sliceable consistency but help it retain moisture with just the right amount of caramelization on top and around the edges.
Here are some common issues you might encounter when making this oatmeal bake recipe and how to solve them!
If your oatmeal turns out too dry, it could be due to over-baking or not using enough liquid. Be sure to bake it covered with foil for 20 minutes of the baking time. If it looks like it’s drying out, check to be sure your oven isn’t too hot.
If it’s too mushy and isn’t cooking in the middle, you might have added too much liquid or used the wrong type of oats. Stick to old-fashioned rolled oats and bake for a little longer than the recipe calls for, if necessary.
Be sure to add a pinch of salt, the vanilla and cinnamon for flavour. If you leave out any of these ingredients your oatmeal bake will most certainly lack flavour. Feel free to add other flavours if you wish, like nutmeg, ginger or other spices.
If after storing it in the fridge the oatmeal bake seems dry, add a splash of milk or dairy-free milk and warm it in the microwave. Warming it up with a little bit of milk with help it rehydrate and soften. Be sure to store it in the fridge, covered with plastic wrap to lock in the moisture.
We don’t recommend adding sugar to this recipe, but if you find it’s not sweet enough feel free to add some brown sugar, maple syrup and/or fresh fruit on top!

Can I make baked oatmeal with instant oats?
We recommend using old fashioned rolled oats instead of instant oats as instant oats can break down very quickly, creating a mushy texture.
Can I make baked oatmeal vegan?
Yes! Omit the eggs and replace them with more mashed banana or applesauce, and replace the milk with your favourite dairy free milk.
How should I store leftover baked oatmeal?
We recommend storing this baked oatmeal in the fridge, covered, for up to 3 days.
Can I freeze leftover baked oatmeal?
Yes! Freeze in individual portions in airtight containers for up to 3 months and then thaw in the fridge overnight. Reheat in the microwave before serving.
Can I use steel cut oats for baked oatmeal?
We don’t recommend using steel cut oats because they create a hardier, dryer texture. Old fashioned rolled oats are best for baked oatmeal.
Can I make baked oatmeal without eggs?
Yes! Feel free to omit the eggs in this recipe and add extra mashed bananas or applesauce instead of the eggs.
What kind of pan is best for baked oatmeal?
We recommend a glass or ceramic square pan that’s about 9-inches by 9-inches, or equivalent.
Is baked oatmeal good for you?
Yes! It’s packed with healthy fibre, protein and sweetened with fruit.
Are baked oats as healthy as overnight oats?
Yes, in fact they have even more health benefits like added protein thanks to the eggs!

Question: can you use frozen berries? Does it affect the amounts of the fruit and/or other ingredients in the recipe?
Yes! We use frozen berries all the time. They tend to colour the oatmeal mixture a little bit, but otherwise they work great
Delicious! I followed the recipe to the letter, making the one banana +2 egg version for more protein. I also threw in a little cardamom because that’s what I do to a lot of my baked goods. There is just two of us, so we refrigerate the leftovers and use the air fryer to reheat and crisp the edges. Thank you for the recipe.
We’re so happy you enjoyed it! Thank you for taking the time to leave your feedback!
I made the one banana, two egg recipe. We LOVED this breakfast. It’s summer here so we serve it cold with a dollop of Greek yoghurt with drizzled honey, it is sensational. Can I leave out the banana all together if I have none? Thank you.
Thanks for taking the time to leave your feedback! You could completely leave it out but your baked oatmeal will have no sweetness. In that case, you can either add some apple sauce, sugar or honey.
This recipe is my favourite! Moist and satisfying with just the fruit for sweetness.
I’m so happy you are enjoying the recipe! Thank you for taking the time to leave your feedback!
