Best Baked Oatmeal
This is my family’s favorite oatmeal recipe! It is dairy-free and gluten-free, but packed with so much great flavor. We love making this healthy baked oatmeal recipe for a big weekend breakfast to meal prep for busy mornings ahead or to feed a crowd. It’s the best way to enjoy a healthy breakfast on a holiday morning! You will find us serving up this make ahead breakfast or our Ultimate French Toast Bake. There is nothing better than a big family breakfast!
What You Will Need
- rolled oats – the hearty base of the best baked oatmeal recipe, if you need it to be gluten-free make sure they are gluten-free certified rolled oats.
- coconut sugar – perfect for an added touch of sweetness!
- baking powder – a little bit to help with the structure for this baked good.
- kosher salt – just a pinch for added flavor and to help with the structure too!
- ground cinnamon & vanilla extract – both are perfect for adding flavor to all of your favorite baked goods.
- unsweetened almond milk – this will bring moisture to the dish. Substitute with regular milk if you aren’t concerned about it being dairy-free.
- eggs – holds it all together and gives structure to this delicious breakfast!
- butter – flavor plus it’s great for making the top crisp and brown.
- apple, blueberries, & peaches – a delicious combination of fresh and canned fruit that we love to use, but feel free to use any of your favorite fruit combinations!
How To Prep This Baked Oatmeal Ahead Of Time
If you want to prep this the night before, this is what you can do:
- Combine your dry ingredients and place in bowl and cover.
- Chop your apples and peaches and store in separate bowls.
- Set out your pan and another bowl for your wet ingredients ahead of time.
The next morning you can throw everything together quickly and pop it in the oven! I wish I could tell you that you could combine it all together the night before, but you would end up with a pan of overnight oats in the morning.
How To Make Healthy Baked Oatmeal
To start things off you can mix together the dry ingredients in a large bowl and the wet ingredients in a small bowl. Then pour the wet ingredients into the dry ingredients and mix to fully combine.
Now you can add the fresh blueberries, chopped apples, and chunks of peaches to the oat mixture.
Use a large wooden spoon to carefully fold in the fruit.
Then pour the mixture into a large prepared baking dish.
Place the baking pan on the middle rack of the oven and bake at 350 degrees F for 45-60 minutes.
Let it cool for a bit and enjoy!
How To Serve Healthy Baked Oatmeal
One of our favorite ways to serve this fresh baked oatmeal is to give it a fresh sprinkling of ground cinnamon and just a splash of almond milk. A drizzle of maple syrup or honey would also be amazing! On the side we love some added fresh fruit, Greek yogurt, a cup of cold brew coffee, a cup of hot tea, or a delicious mango smoothie! Or for a little added protein you could hard boil some eggs!
- Fruit variations: you can easily substitute other fruit for either the blueberry, apple or peaches! Feel free to use raspberries, blackberries or pears!
- Add-Ins: you can toss so many different things into this simple recipe, like nuts, chocolate chips, shredded coconut, flax, etc.
- Storage: any leftovers can be kept in an airtight container in the refrigerator for up to 5 days.
- Freezing: after it has cooled you can either cover the entire pan and store in the freezer for up to 3 months. Or you can cut into individual portions, wrap them in plastic wrap, and store in a freezer bag so that you can reheat them 1-2 at a time.
- Reheating: so simple! You can either place it back in the oven at 350 degrees F until heated through or place in the microwave for a quick breakfast.

This was a big hit in our house. I didn’t have peaches so i just used different berries and it was delicious! And It made the house smell divine when it was baking 🙂
Would like to try this recipe for brunch tomorrow. Can I use egg whites instead? And how many?
Hi Suzanne – I have only ever made this with whole eggs! Let me know if you try it with egg whites though!
This is the perfect make ahead dish for company or just for weekly meal prep. Delicious and a crowd-pleaser! Thanks Erin!
Our family loved this breakfast bake! We love that it is refined sugar free and can easily be prepped ahead of used for meal prep. If you like oatmeal that is slightly sweet and packed with fruit this recipe is for you.
so happy to hear that, Angela! This is a family favorite in our house 🙂 Thanks for taking the time to leave your feedback – I really appreciate it!
Great oatmeal recipe but can you give me the macros please?
Hello! I want to make this tomorrow morning. If I’m using frozen blueberries, should they we fully defrosted and at room temperature before adding them to the mixture? Also, can this be made ahead of time, refrigerated overnight, and then baked in the morning? Thank you! Can’t wait to make this!
Hi Dayna! You do not need to defrost frozen blueberries – just toss them right in 🙂 I wouldn’t recommend combining ALL the ingredients and then baking in the morning as the oats will soak up the liquid and you would kind of have an overnight-oats situation … I don’t know how it would turn out after allowing the oats time to soak up so much. I usually just prep everything the night before (combine all your dry ingredients and cut up fruit, etc.) and then throw together quickly in the morning. You could just bake it the night before though – it does reheat really well. Hope that helps!
That’s what I figured. Just wanted to check. Thanks so much!!

Is this quick oats or rolled oats? Can’t wait to make this with my kids today!

Christine Geffner says
Hi Erin! I made this yesterday and it is so delicious! Had an enormous bag of frozen blueberries and everything else already around. I will certainly be making this again. Seems like a perfect one to customize, based on what fruit you have.
Thanks so much for all that you do. I’m definitely finding comfort in cooking these days.
Up later-your Buffalo Chicken Meatballs.
Hi Christine!! Thank you so much for your feedback – I greatly appreciate it!! Ooooh those Buffalo Chicken Meatballs sound amazing right now!! Hope you are doing well in these strange times!
I eat oatmeal every morning, and this recipe looks like a great option to mix things up and also for grab and go. Do you think I could omit the sugar altogether?
Hi Crystal! Yes, you can definitely omit the sugar altogether if you want! It will still turn out (just not as sweet, of course!). Let me know if you have any other questions!
