Blueberry Baked Oatmeal: Ingredients & Substitutions
Ok, now onto substitutions! This is a very versatile recipe so here are a few ways to tweak it if you wish, although I always recommend making the recipe exactly as it’s written! 😉
- Old-fashioned oats: Quick-cooking oats can be used in place of old-fashioned, you will need to decrease your baking time by about 10 minutes.
- Almond meal: you can replace the almond meal with an extra ¼ cup oatmeal.
- Granulated Sugar: coconut sugar, light brown sugar, honey or maple syrup are all good substitutes for granulated sugar.
- Salted butter. coconut oil or unsalted butter are good substitutes.
- Milk: choose your favorite milk, whole milk, 2%, coconut milk, almond milk, etc.
- Greek yogurt: Choose your favorite yogurt, if using plain, increase the sweetener by at least 2 Tablespoons.
- Blueberries: choose your favorite berries, they all taste amazing.
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).
Then, add the milk to the wet ingredients and whisk to combine.
Next, add the dry ingredient mixture to the wet ingredients and use a spatula to stir to combine.
Then gently fold in the blueberries. If you smash them too much the baked oatmeal will become purple/gray in color!
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. 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. 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- 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!
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.

These look so delicious and easy! My kind of recipe 🙂 Do you use plain greek yogurt? or flavored?
I have used both plain greek yogurt and honey/vanilla greek yogurt! I prefer the honey/vanilla but any variety would work great!
This looks amazing! I’m dairy free, what could I use in place of Greek yogurt?
There are many varieties of dairy-free yogurt out there!!!! Pick your fave!
My daughter is allergic to nuts. What would you substitute for the almond meal? I’d rather it stay gluten free but it doesn’t have to.
Hey Lilith! I would substitute an extra 1/4 cup of oats or oat flour for a nut-free version!
For this recipe can I use non-frozen blueberries?
Hey Julie! Yes you can! Your cooking time will be slightly shorter when using fresh!
Are you sure it’s 2 cups of milk cuz it’s really soupy. I had to add another cup of oats and almost another cup of flour….. and transfer to a huge pan to accommodate. Yikes!
Hey Kristi! Yes! It will be very soupy when it’s put into the oven…but the oats absorb the liquid beautifully!
Does this have to be made with frozen blueberries or can I use fresh?
Hey Megan! You absolutely can use fresh! The bake time will be a tad shorter!
Hi Laura,
This recipe is an absolute stunner! You have single-handedly managed to get me to give up a weekend stack of pancakes for Baked Oatmeal instead! I was inspired by your recipe and adapted it with a few tweaks of my own to make Baked Strawberry oatmeal. It was the stuff of cozy weekend dreams, to say the least.
Do check out my blogpost (at the link below) with a special shout out to your blog (which I LOVE, by the way) and backlink to your recipe here! Thanks for converting me to a Baked Oatmeal lover! I am eternally grateful 🙂 <3

Thank you Winola! I’m so glad you enjoyed the recipe! 🙂
How big is a bar (like inch x inch) and how much protein per bar?
Is it suppose to be soft yet firm on the bottom or should i baked it a little longer?
Hey Krystle! It is totally a preference! I like to leave it a little soft, especially if serving/reheating the next day so it doesn’t dry out! But again, it depends on exactly how you enjoy your baked oatmeal! It does firm up as it cools!
Made this today for breakfast and substituted the almond meal for chopped walnuts. Super delicious, will definitely be making this again!
Thank you so much for stopping by Maria! I am so thankful that you enjoyed this recipe! 🙂 It means the world to me to hear it! Walnuts sounds like a super delicious substitution!
