Blueberry Baked Oatmeal is the perfect filling breakfast recipe and it’s the ONLY way I like to eat oatmeal. It is so easy to make with blueberries packed throughout. The texture is like a soft oatmeal bar married a granola bar – you’re going to love it!

The BEST Baked Blueberry Oatmeal

This recipe is the best for people who love oatmeal and also people who hate oatmeal. What I often hear from people who do not like oatmeal is that the texture is not their favorite (this is my problem). This recipe brings in the best parts of oatmeal with a less oatmeal-y texture: It’s like oatmeal but more like a soft oatmeal granola bar. The flavor is incredible and the blueberries add so much flavor.

A baked oatmeal granola bar is the perfect grab and go breakfast or serve it with a drizzle of maple syrup. It’s also freezable and even the pickiest eaters love it!

Ingredients Needed

  • Blueberries: Fresh of frozen blueberries are fine, just make sure to thaw and drain frozen berries.
  • Eggs: These give the baked oatmeal structure.
  • Oats: I use old fashioned oats for this recipe (rolled oats). While you can use quick cooking oats, I don’t recommend it.
  • Baking Powder: Keeps the bars soft, almost like one of those grocery store oat bars.
  • Brown Sugar and Applesauce: These are for sweetness and the applesauce makes it so we don’t have to use any oil.
  • Milk: You can use any kind of milk (regular, 2%, nonfat) or nondairy milk, like oat milk, almond, or coconut milk.

  1. I love all oatmeal and in every form. Haha! Funny how different people take to different things. I love a baked oatmeal too – it’s just so easy. This looks perfect! Thanks so much for sharing it!

  3. You mentioned freezing it, how do you reheat it? Looks delish, but since I am the only one that would eat it, would like to know more about freezing. Thanks!

    1. I slice it into squares and freeze it in ziploc bags. You can leave it in the fridge overnight to defrost, then microwave it. Or (if you’re like me and forget to think ahead) just microwave it frozen!

  4. This recipe sounds so yummy! Since we aren’t big fans of blue berries and they aren’t something I generally have on hand, I’m wondering if raisins could be used as a substitution? Should they be boiled first to plump them up? Thanks! Happy New Year! Looking forward to hearing from you every day!

    Reply

    1. Yes! I think any fruit substitution would work. Raisins, craisins, strawberries, you name it! As for plumping, yes, if you like them plump you can do that. I’m not a raisin eater so I’m not sure how that would work, but if you add them plump they should just cook in the oatmeal like the blueberries do.

  5. We were in bed by 10:30 (the girls were asleep the minute their heads hit the pillows at 9:00, I think), and I wish I had this to eat this morning!  I love oatmeal, but don’t always have time to cook it in the morning.  I will definitely try this, and have it ready ahead of time!

  6. My boyfriend and I were in bed by 10:30 and it felt GREAT!  Actually woke up and made oatmeal and wish I would’ve made this!

  7. I do love oatmeal and I do think I would love this baked oatmeal. I’ve never made baked oatmeal but not I have another New Years resolution to add to my list: make baked oatmeal! Looks great, Dorothy!

  8. Lovely pour shot and this seems like an easy enough breakfast that looks great. I’m not a breakfast person either. Happy New Year!

  9. OMG you crack me up girl, watching the ball drop at 9pm is utter hilarious. It’s New Years somewhere in America, right? 😆 I can let you know next NYE when it’s midnight here in England and you can go to bed even earlier, ha!

    I love oatmeal, especially golden syrup oatmeal. And I love blueberries so this is like a match made in heaven. I hope you and the fam had a wonderful Christmas.

  10. I’m not a huge oatmeal fan too, but I will give this a try. 
    As for NYE, hubs and I enjoyed some Russian potato salad (it’s a tradition) and my 3-ingredient soufflé cheesecake. We stayed up will 1am watching TV shows on Netflix. Haha
