This baked oatmeal is everything that you want breakfast to be: warm, sweet, and filling! I make this recipe often because it is so easy to put together and is so easy to save as leftovers for another morning. With each bite you get that sweet taste of baked berries combined with delicious chewy oatmeal. I find that regular oatmeal can sometimes be too mushy or soggy, but this baked oatmeal has the perfect texture.

My family loves to sprinkle some walnuts and a small drizzle of maple syrup on top to complete this tasty dish. Baked oatmeal is my favorite way to eat oats, and after you give this recipe I try, I hope it becomes yours too!

Recipe FAQs

How do you know when baked oatmeal is done?

You can tell when the oatmeal is done if the oats are only slightly jiggly in the middle. As the oatmeal cools, it will continue to thicken to the perfect consistency. Be careful not to take it out too early because you don’t want your oatmeal to be runny. You can also check to see if your oatmeal is done by looking for crispy, lightly browned edges.

Should I use old fashioned or quick oats?

You can use either type of oat in this recipe. Old fashioned oats will give you a little bit more crunch while quick oats result in a slightly more chewy bar.

Do I need to soak my oats before I use them? 

It is not necessary to soak your oats for this recipe. That being said, you can soak them in water for 3-6 hours if you prefer. The biggest benefit of doing so is that the oats will be easier to digest.

Expert Tips

  • To add a little bit of flare to your oatmeal, try experimenting with different spices! Nutmeg and cloves are a good place to start. 
  • The fruit will add quite a bit of extra moisture, but allowing the oatmeal time to cool helps mediate how much liquid is left in the dish
  • Make sure to use old fashioned oats! We found that with quick oats, the baked oatmeal was still quite wet after it came out of the oven which makes it difficult to eat and not as enjoyable. 
  • Allowing the baked oatmeal to cool down helps cook off some extra moisture and the oatmeal will settle, making it easier to slice and serve!
  • You can add chopped pecans or walnuts on top of the baked oatmeal at the same time you add the fruit before baking, or afterwards as a nice garnish!

How to Serve and Store Baked Oatmeal 

Baked oatmeal is one of the best breakfast dishes! You can serve it alongside a tropical smoothie or eggs in the morning. There are also unlimited toppings and add-ins you can include with your baked oatmeal. You can drizzle on some syrup, whipped cream, greek yogurt, or chopped nuts! The possibilities are endless. 

If you have leftover baked oatmeal, allow it to cool completely before storing it in the fridge. You can either cover the baking dish with tin foil or plastic wrap, or transfer it into an airtight container! When ready to enjoy this delicious dish again, simply reheat a serving in the microwave for about 40 seconds or until warm. Baked oatmeal is also great cold if you want to try it that way!
