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.

    Loved this, I did it for a family meal prep. I added walnuts and cranberries as well as the blueberries. DELISH!!

  2. Karen Kessler says:

    Can this recipe be made using a muffin pan, and if so, how long would you bake it?

    1. Laura Fuentes says:

      I haven’t tried it on a muffin pan but it should work. I imagine around 18-22 minutes, but check that the oatmeal has set.

  3. Elizabeth says:

    I’ve been trying different recipes with blueberries and oatmeal and I can say without a doubt that this is the BEST! The consistency is cake like and so good! I followed your recipe exactly and it came out perfect! Thank you for posting this!

    1. Laura Fuentes says:

      Thank you for sharing your feedback with others Elizabeth!

  4. Tracy says:

    Yummy, super delicious! Thanks so much. I’ll be making it again.

  5. David Cheung says:

    I’ve made this a few times and it sure beats traditional oatmeal!
    I used 1 extra egg and add 1/2 cup of sifted flour (ap) for better texture!

  6. Gina says:

    If using frozen blueberries do you let them thaw first or throw them in frozen?

    1. Laura Fuentes says:

      Feel free to throw them in frozen. They’ll thaw and heat up just fine. Be prepared for your oatmeal to turn … purple 🙂

  7. Layra says:

    Is there anything I can use in place of honey?

    1. Laura Fuentes says:

      You can omit it, use maple syrup, or a sweetener of your choice.

  8. Mo says:

    Can we use apples instead of blueberries? If so, how much? Thank you!

    1. Laura Fuentes says:

      Absolutely. I’d use the same amount. 1-2 apples

  9. Dawn De Koker says:

    The Blueberry Baked Oatmeal is delicious! I substituted half a banana for the egg and it worked well. Thanks for posting.

  10. Toni says:

    I enjoyed this a lot and my picky 2.5 year old actually ate it. I’ve made baked oatmeal before and I’m sure this recipe would’ve been delicious as written. I noticed another commenter suggested adding in some flour and an extra egg, so I tried it with half AP and half whole wheat. I think it made it a bit more cake-like which may have been what convinced my little girl to eat it. Thanks for sharing a great recipe Laura. I’m new to your blog and look forward to trying more wonderful meals.

    1. Laura Fuentes says:

      I’m so glad your family enjoyed this Blueberry Baked Oatmeal recipe, Toni! Thank you for trying my recipe and I too look forward to sharing more with you!

    Hi everyone! Does anyone have an idea for a honey substitute? I will be feeding this to a 9 month old who can’t have honey yet. TIA

    1. Laura Fuentes says:

      You can use maple syrup. Enjoy!

  12. Sarah says:

    Can I substitute milk with almond milk? Thanks!

    1. Laura Fuentes says:

      Absolutely, Sarah. You can substitute milk for almond milk in this blueberry baked oatmeal recipe. Enjoy!

  13. Whitney says:

    Love this recipe! It was a hit with my husband and brother-in-law, both are very picky eaters. I made a few modifications by adding a mashed banana and I used 1 cup of plant milk instead of 2. I wanted it to be a little sweeter.

    1. Laura Fuentes says:

      I bet the mashed banana added sweetness! Great add-in!

  14. Cherie Duphorne says:

    Hi Laura! I’m wondering if I could use steel cut oats in this recipe instead of rolled oats, and if so do I need to make any adjustments to the other ingredients (more or less milk?) or to the time and temperature?

    1. Laura Fuentes says:

      Hi Cherie, you can absolutely use steel-cut oats for this recipe. However, for every cup of oats, you’ll need 4 cups of liquid. And, the baking time will increase to 45-50 minutes. I also recommend you stir them half way through. Enjoy!

  15. Nikki C says:

    Made this today with Apple, pear, peach cinnamon, nutmeg and maple syrup instead of honey. It was delicious! Thank you!

    1. Laura Fuentes says:

      That combo sounds delicious. Thanks for sharing, Nikki!
