Throughout the years I have gotten better at eating breakfast.

For so many years I skipped “the most important meal of the day” because I was straight-up lazy. 

The thought of rolling out of bed and immediately dirtying my kitchen was not high on my list. 

But, luckily for all of us, I came up with this tasty baked blueberry oatmeal that will straight up get you to start LOVING breakfast. 

Not only is it easy to make BUT it reheats like a dream. That way if you’re like me and don’t feel like cooking all you need to do is pop it into the microwave and give it a little zap. 

Then you’ll be rewarded with a big plate of wholesome goodness. 

Baked oatmeal for the win!

Can I use non-dairy milk in this recipe?

Of course! 

I personally like cow milk but I have successfully tested this recipe using almond, cashew, oat, and soy milk. 

It turned out totally fine and equally delicious. 

If you use vanilla-flavored non-dairy milk just make sure you’re not adding in too much additional sugar. 

What if I don’t like blueberries?

I made a fall version of this for my baked cranberry oatmeal but if you want to keep this summery I have a few other delicious ideas!

Try using fresh or frozen raspberries, blackberries, strawberries, peaches, or even cherries. 

What about if you’re craving chocolate? Try these chocolate baked oats!

How do I store baked blueberry oatmeal?

Rarely, Art and I will finish this whole tray of oatmeal. 

I mean, I love oatmeal but I’m not about to sit down and eat half an 8×8 tray. 

Luckily for us, this recipe stores LIKE A DREAM!

We like to cut the whole tray into squares, cover the dish so it’s airtight, and store it in the refrigerator for up to 5 days.

How do I reheat baked oatmeal?

The re-heating capabilities of this baked oatmeal are what I love the most about this recipe! 

Add it to a plate and microwave for 30 seconds to 1 minute. The time depends on your microwave strength and how hot you want your oatmeal. 

You’ll be rewarded with a hearty, wholesome, warm breakfast dish. 

I love to drizzle maple syrup on top after it comes out of the microwave. 

I’m a sucker for a little sweetness in my breakfast.

If you’re looking for something even more delicious you could top this oatmeal with a little fresh whipped cream to create a wholesome dessert treat. 

I have tried this a few times and honestly – SO GOOD! 

Trust me, you’ll love this little twist.

Can this be assembled the night before and baked off in the morning?

I made this for my husband for work. He's a heavy equipment mechanic and he loved this. Kept him full until lunch and he shared with some Co workers who loved it too. Looks like I'll be making this again quiet often.

Hi Nicole - thank you so much!


Friday 13th of July 2018

I´ve made this with a bunch of different fruit combos (apple-blueberry is my personal favorite) and I do it without the syrup because I´m diabetic. It´s still my favorite breakfast! Thanks!

Can this be frozen and reheated at a later time? Looks delicious!


Sunday 11th of February 2018

Hi Crytal - Yes, I have frozen it before in little squares and then warmed it up in the microwave in the morning. Hope you enjoy the oatmeal!

substituted with almond milk and a touch of almond flavour - could do the same with coconut for extra flavour boost
