How to Make Blueberry Baked Oatmeal

This blueberry oatmeal is very easy to make, but we’ll walk through the steps together to ensure your success! Don’t forget to watch the video too!

Begin by combining the dry ingredients in a small bowl. By doing this first, you ensure that the dry ingredients are evenly distributed in the final product.

Next, in a large bowl, whisk together eggs, Greek yogurt (or sour cream), and vanilla extract until the mixture is homogenous (uniform throughout).ย

Then, add the milk to the wet ingredients and whisk to combine.ย

Next, add the dry ingredient mixture to the wet ingredients and use a spatula to stir to combine.ย 

Then gently fold in the blueberries. If you smash them too much the baked oatmeal will become purple/gray in color!ย 

Note: Lots of Liquid

One thing to note about this berry baked oatmeal recipe is that it is very liquidy when you pour it into the pan to bake.ย Do not let that worry you, the oats will absorb the liquid as it bakes.

Bake & Cool

Bake the blueberry baked oatmeal until the edges are golden brown and the top is set. Let cool for at least 10 minutes, and serve warm! Note: Bake time varies depending on the type of oats you use. Be sure to watch it carefully.

To Prepare in Advance

Bake the night before & reheat. ย I usually make this Blueberry Baked Oatmeal the night before, store it in the fridge, then just warm in the oven the next morning. It takes 5 minutes to throw together and 35 minutes to bake, plus it uses ingredients I almost always have on hand!
Make batter ahead of time and bake in the morning. You can also make the batter the night before – just leave out the blueberries-ย  and store it in an airtight container in the refrigerator. In the morning, fold in the blueberries, spread it into a baking dish and bake!ย

Serve

I love serving this blueberry baked oatmeal with a glug of pure maple syrup! You can also add a dollop of homemade whipped cream, homemade peanut butter (for a PB&J vibe), homemade almond butter, or another favorite – slather it with this homemade cinnamon honey butter!

Store/Freeze

Store any leftovers in an airtight container in the refrigerator for up to 5 days, or in the freezer for up to 2 months! To reheat, simply warm in the microwave or the oven (set to 300 degrees) until warmed through.

    I made this almost directly from the recipe. Instead of almond flour I used regular AP flour and baked it for 35 min using fresh blueberries. It was naturally sweet, which was great for my son who has ADHD (trying to cut back on processed foods and sugary foods.) I expected to eat on it for breakfast all week long (today is Monday,) but my 2 teenage boys ate 80% of it this morning! My husband and I barely got any. So much for leftovers! I will definitely be making it again. I like the idea of making it the night before and just heating it up in the morning. Thanks for the recipe!

    Made these yesterday and they are just about gone! Everyone loves them. I added 1 Tbls of honey for a little sweetness. Iโ€™ll be making them again soon with a few tweaks. Thanks for sharing. ๐Ÿฅฐ

    I thought this looked like more than eight servings too, but one serving was just filling enough. I used 3 cups fresh blueberries and thought that was perfect. Coconut sugar has a very nice distinct taste with oatmeal, I liked it. Served fresh it didnโ€™t need any topping. I also suggest Fairlife brand nonfat milk, it cuts a few carbs and adds a bit of protein vs regular cows milk.

  4. Can anyone help me figure out why the bottom is so soggy still? I’ve probably cooked it an extra 20 minutes. Only thing I changed was using cow’s milk as the milk.

    Delicious. This recipe was a great alternative to our usual morning oatmeal.

    I followed the recipe (substitutions: extra oats for the almond meal, maple syrup for the coconut sugar, frozen mixed berries). I did sprinkle some turbinado sugar on top instead of the cinnamon sugar. I drizzled a tsp of maple syrup over top when serving.

    I must have made this recipe 40 times by now. It’s perfect for daily breakfasts, weekend breakfasts with people over, excellent to take over to someone’s house, or even perfect as a meal for new parents! I’ve done it all. I used all kinds of berries, I also made it with apple sauce instead of yogurt for a dairy free version. I love this recipe. Thanks so much for sharing it with us!
