Blueberry Baked Oatmeal
I love a big oatmeal bowl for breakfast in the morning. I usually either cook it on the stove, make overnight oats or when I am in a rush grab a handful of homemade granola.
This blueberry baked oatmeal recipe is another easy alternative to classic oatmeal. It’s quick to make in bowl and takes less than 10 ingredients. No matter how you customize it, it always tastes delicious!
I got this blueberry oatmeal bake when I visited the Amish country in Ohio. It’s great for shelf cooking and perfect for meal prep!

I made this for a family reunion and it was a huge hit. I used quick oats and fresh berries as substitute. Instead of layering the bottom with fruit I mixed it with the batter. It turned out moist and perfect!
Great idea! I love how you made it your own. Thanks for sharing and your great review!
What kind of oil do you use?
I used vegetable oil or canola oil works great!
Best Baked Oatmeal recipe I’ve had.
I had some coconut to use up so that replaced the butter. And I traded out the brown sugar for natural maple syrup. Cut up a tart apple – Delicious.
Will be making this recipe with or without changes. Thank you.
That is perfect! Thanks for trying the baked oatmeal recipe!
My family loves this recipe!! It’s so good!
So glad your family enjoyed the baked oatmeal!
Can you make this with quick oats and fresh blueberries?
Yes you could, enjoy :)
This recipe is so good! Part of our family likes it with blueberries and part likes it with strawberries, so we make it half and half. Either way…delicious and easy – a fun recipe to make with young cooks.
Love that you do half and half, so yummy!
I love making this without the blueberries and topping it with banana’s and Greek yogurt. So yummy!
Sounds yummy! :D
I never have like oatmeal stuff and when I tried these I fell in love. It is so yummy and even my kiddos eat it.
I’m so happy to hear it was a hit!
My kids don’t care for regular oatmeal so I tried this and the loved it!
I’m so glad they loved it!
The entire family loved it, and with next to no effort, we’ll be making it regularly!
I’m so glad to hear your family loved it! Thanks for leaving a comment and review. :)
Omgosh. Soooo good and easy for a beginner bread maker like me. Cooking and baking are my thing. Bread making I could never get right. These bread bowls are the best. Hubster approves!! I made homemade broccoli soup to serve in them. Thank you! I had already downloaded some of your bread recipes to try. Then saw this and already had soup going. Have a great day and God bless!
This was a huge hit in our household – so delicious! I have your cookbook too and I haven’t tried anything that I didn’t enjoy from your recipes. You are inspiring!
I’m so glad you enjoyed it. Thank you for your kind comment Cara, it made my day! :)
We made this this morning and it was a huge hit! We used frozen slice strawberries and topped it with half & half and brown sugar. It was so good! No leftovers. We’re going to try blueberries next time. Thank you!!! It’s nice to have another recipe for an easy, warm breakfast. Thank you! We love all your recipes!!!
So excited to make this! Can you make this in a 9×13? Would you just double the ingredients? Change cook time at all?
Hi Leah! Yes, you could definitely double the recipe and bake in a 9×13 pan. I would check after 25 minutes and then continue to back until the edges are slighty crisp and the middle is set.
So yummy! We made it with melted butter and maple syrup and we didn’t have any leftovers, it was so good! Definitely making again.
Yummy! I love oatmeal and blueberries. I will have to try this baked kind. :)
The perfect breakfast! Love starting my day off with this
Thanks for these recipes.. will try them!
Hope you enjoy!
