Blueberry Baked Oatmeal

Today, I’m going to share with you the best healthy baked oatmeal recipe.

Do you ever have mornings where you want something hearty for breakfast but wish you can have most of the recipe prepared the night before? This blueberry oatmeal bake is just that! Plus making this recipe is simple and your oven does all the work!

I’m a big fan of oatmeal, and thankfully so is my husband. Until now, I’ve made individual jars of overnight oatmeal that have been rocking our breakfast world for a couple of years. The Bananas Foster is one of our favorites, closely followed by the Peaches and Cream and Strawberries and Cream recipes. BUT, nothing beats a warm bowl of cake-like oatmeal. Nothing. And that’s exactly what you get with today’s recipe.

This Blueberry Baked Oatmeal is a delicious healthy breakfast that can be made ahead of time and reheats great!

While single-serve oatmeal jars are very practical, some mornings I feel like eating something right out of the oven with a little whole milk over the top. This baked oatmeal recipe is the good kind of breakfast comfort foods.

How to make healthy baked oatmeal

I’ve made this recipe with both frozen and fresh blueberries, so no matter what time of the year you are making this recipe, it can be done! With frozen or wild blueberries, your oatmeal might turn a little purplish because of the juices, but otherwise, the taste is the same.

What if you don’t have blueberries? I also make this with strawberries or cranberries and a little orange zest! Clearly, this is one flexible recipe.

I love creating versatile recipes. Fixing healthy and tasty meals for your family shouldn’t be a struggle and it’s yummy meal ideas like this that make it possible all year long.

Make-Ahead Blueberry Oatmeal Bake

How do I make this ahead of time? I measure out the dry ingredients and place those inside my 9×9 dish. In my blender jar, I combine all the wet ingredients and place that in the refrigerator. In the morning, I combine the two, add the blueberries and bake!

Putting the recipe together once it’s pre-measured takes two minutes, and the 35 minutes it takes to bake I’m usually in the shower, getting myself ready and prepping lunches.

When I look at this recipe, the amount of honey called for does not show up. How much honey do you use?

Also, can you make this a day ahead of time and warm it up in the morning?

    Laura Fuentes - October 5, 2015 Reply

    the recipe calls for 1/3 cup.

      What is the calorie content?

        Evelyn, I do not calculate calories in my recipes. I focus on using fresh and real ingredients instead. You are welcome to plug the ingredients into a calorie calculator. Enjoy!

Hi Laura,
Could I make this dairy free? I was thinking of using cocounut milk and earth balance butter so my daughter could enjoy it. Also, could I use raspberries or strawberries instead of blueberries?

    Laura Fuentes - November 28, 2015 Reply

    Absolutely! That will work!

      Elisha - November 29, 2015 Reply

      Thanks Laura!

So, I followed the recipe exactly and it was watery not a thick batter like you mentioned and cooking time was almost doubled

    Helen - June 7, 2016 Reply

    Yes mine was also watery.

      Laura Fuentes - June 7, 2016 Reply

      did you use old fashion oats or quick oats? this is meant to be used with old fashion oats.

I’ve always wanted to try baked oatmeal & this was the first recipe I tried. I was in a hurry last night so I forgot the milk until halfway through the baking time…. But I added it and thankfully is still cooked. Made it last night so I could take it to work this morning. The flavor is SO GOOD!!!!!! & the texture is just right. How have I not done this before?! I will be making this recipe again & again! Thanks for sharing!

    I”m so glad it was a success Sarah!

Thank you so much for sharing your recipe. I am trying to clean up my eating habits, eating only “real” food, minimally processed, no refined sugar, healthy fats, and this oatmeal ticks all those boxes. I am not a big blueberry fan, but figured I could use the base and add the things I like. I made this as soon as I discovered the recipe on Pinterest, and IT IS WONDERFUL! I made it without the blueberries, and my favorite way to eat it so far is warm, with a sprinkle of unsweetened coconut, a handful of walnuts, and sliced bananas, so yummy. I encourage everyone to make this delicious oatmeal!

    Laura Fuentes - January 9, 2017 Reply

    Thanks for sharing how much you loved this Mimi! Try it with frozen peaches one time and a little cream on top. OMG, so good!

Sierra - May 9, 2017 Reply

I have made this recipe several times. I always double it for a 9×13 pan and I use different “extras” depending on what I have on hand. Raisins, cinnamon, and walnuts are a great way to go! Even my super picky kids love it warmed up and served with yogurt. Great texture and super filling!

    Laura - December 4, 2017 Reply

    Hi Sierra! When you double the recipe, do you increase the cooking time? Thanks!

Robin - June 10, 2017 Reply

I have made this a number of times. Super easy and very good. I like adding peaches with the blueberries.

Brooke - June 20, 2017 Reply

Thanks for sharing your recipe. I’m a fan of oatmeal for breakfast, so I usually rotate making steel cut oats, DIY instant oatmeal, baked oatmeal cups and overnight oats. I came across your recipe and it was an instant hit. This will definitely become part of my oatmeal rotation. Looking forward to trying your recipe with other fruits and add-ins!

    Laura Fuentes - June 21, 2017 Reply

    I am so glad you enjoyed it! I have many recipes on here for overnight oats that I am sure you will love. 🙂

I made the oatmeal this morning. Really easy, Added cinnamon and walnuts and used fake sugar instead of honey and skim milk., canola oil instead of butter. Its pretty tasty to be so easy. It looked like soup when mixed, but like a cobbler when done. I will be making this a ton come this winter. Thanks a bunch for the recipe.

Carla - September 29, 2017 Reply

Have you ever froze this? If so do you freeze it before or after baking?

    Laura Fuentes - October 6, 2017 Reply

    You can definitely freeze it but the texture of oatmeal after thawing and heating changes.

Sara - January 14, 2018 Reply

Just made with cranberries that they were practically giving away at the store. Delicious!!!

    Laura Fuentes - January 15, 2018 Reply

    What a terrific idea!

Nisha - January 22, 2018 Reply

Can you beatitude soy milk? And instead of honey, agave syrup? Thanks!

    Laura Fuentes - January 22, 2018 Reply

    you can use any type of milk you like and agave instead of honey, of course. Enjoy!

THESE IS LEGIT. The BEST oatmeal I’ve ever had.

Jeanne - June 13, 2018 Reply

Just took this out of the oven, looks wonderful. A small bite proved it is just what I’m looking for. I added a few walnuts I had left over from making banana bread. I plan to add some cinnamon and apples in the future. Love the make ahead idea.

    Laura Fuentes - June 13, 2018 Reply

    I bet it was delicious with added walnuts. Thanks for trying my recipe!

April - July 6, 2018 Reply

Looks so good. Plan to make soon for my son and myself. Hubby won’t eat oatmeal. Going to add walnuts too for some extra protein. Quick question—since just two are eating, would it store okay in fridge for a couple of days? Thanks so much!

    Laura Fuentes - July 7, 2018 Reply

    Absolutely. This refrigerates well, up to 4 days. Simply heat and add a little liquid (like milk) and enjoy. It tastes like cake. Feels like bread pudding… but it’s made with oats.

April - July 22, 2018 Reply

This recipe was very disappointing. I followed it exactly except added cinnamon. It was very watery and despite longer cooking time, it didn’t seem to set. It had the same consistency as stovetop oatmeal so really what’s the benefit of this long cooking time if it’s like regular oatmeal. I used regular rolled oats and exact ingredients. Since I used organic ingredients, it was an expensive “experiment”.

    Laura Fuentes - July 26, 2018 Reply

    Did you omit the egg? I make this baked oatmeal every single week. And it calls for old fashion oats (I’m assuming that’s what you mean by regular rolled oats).

      April - August 13, 2018 Reply

      I’m coming back to amend my review. Yes I used rolled oats. After the oatmeal sat for about 30 minutes it seemed at set up more. If I make it again I may use less milk. I did use an egg and followed everything closely. Thanks.

My son and I loved this!!
My daughter is allergic to eggs – any ideas on how to make it “set up” without an egg?

    Laura Fuentes - September 2, 2018 Reply

    Make a flax egg substitute. easy! will work great.

Nelly - January 16, 2019 Reply

This was easy to make and my daughter who is picky even ate it! I’m going to try with chocolate chips next time.
