This Healthy Blueberry Baked Oatmeal is one of my favorite breakfasts!
Made with only 11 ingredients, (many of which you likely have in your pantry or refrigerator), packed with healthy whole grains, and bursting with sweet blueberries – it feels more like a treat than a nutritious breakfast!
(If you’re looking for the treat version check out this Healthy Blueberry Crisp!)
There are few things better on a chilly morning than a big bowl of warm, cozy oatmeal, right? (Maybe a Healthy Blueberry Muffin.. equally as delicious!)
For every ounce of me that loves oatmeal, there is equally the same amount of me that hates washing the pan from the oatmeal after you cook it on the stove.
IDK why, but it’s seriously always so difficult to clean!
Baked oatmeal is waaaay better for a number of reasons.
Why We Love Baked Oatmeal with Blueberries
- Cook once, eat 4 times! – This means there is only 1 time clean up.
- Portable – Can be eaten on the go or on a dish!
- Tastes great cold or warm – I prefer it warm but it’s totally yummy right out of the fridge.
- Has only 11 ingredients – nothin’ fancy – all pantry staples you probably already have!
- Takes under an hour to make!
I love making this Healthy Blueberry Baked Oatmeal on Sunday to have in the fridge for the week ahead. It takes the guesswork out of deciding what to have for breakfast, and it’s just simple to meal prep! Here’s what you need to make it.
Baked Blueberry Oatmeal Ingredients
To make blueberry baked oatmeal you’ll need:
- almond milk
- cinnamon, ground ginger, nutmeg
- old fashioned oats
- berries
- coconut oil
- honey
- an egg
You can find substitutions for all of these ingredients below in the green shaded substitutions box.
How to make blueberry baked oatmeal:
Making this baked oatmeal couldn’t be easier.
- Take all your ingredients
- Mix them together
- Pour them in a greased 8×8 baking dish.
You can even double this recipe – just put it in a 9×13 baking sheet.
30-35 minutes in the oven and you’ll have perfectly baked blueberry oatmeal!
Baked Blueberry Oatmeal Substitutions
This blueberry baked oatmeal can be tweaked for whatever diet/ingredients you have on hand! Here are some substitutions we recommend:
Fruit substitutions: Baked oatmeal is pretty flexible and you can make a lot of substitutions to it. You can sub in any type of fruit or berry in this recipe. I’d check out this Chocolate Peanut Butter Baked Oatmeal if you’re looking for something a little more decadent!
Frozen berries: I haven’t tried this with frozen berries – but I think it would work. I would thaw the berries completely and allow excess liquid to drain off before adding them to the batter.
Honey: You can sub honey for maple syrup or agave. I have not tried this with stevia so I’m not sure how that would work.
Vegan Baked Oatmeal: Sub egg for one flax egg, sub honey for maple syrup, make sure to use a dairy free chocolate chip
Gluten Free: make sure you’re using gluten free certified rolled oats.
Milk: You can use any type of milk in this recipe. Regular dairy/non dairy will work!
Optional add ins: chopped nuts, more chocolate, shredded coconut, fresh fruit
Steel Cut Oats: You can use steel cut oatmeal in this recipe. Use 1 cup of steel cut oats and 2 cups of liquid/milk. We have a Baked Steel Cut Oatmeal recipe that you can also follow!
Quick Cook Oats: I have not tried this with quick cook oats and wouldn’t recommend it. I don’t think that it will hold up/cook correctly with the smaller oats.
Baked Oatmeal Cups: I haven’t tried baking these in muffin cups but I think it would work! The only thing I would say is it will be harder to clean up and it might stick to a muffin tin. I would grease the muffin tins or use silicone baking liners. You can bake for a little less time.
Can you prep baked oatmeal with blueberries ahead of time?
Yes! Absolutely! Mix together all ingredients and store in the refrigerator for up to 24 hours before you’re ready to bake.
How long can you keep Baked Blueberry Oatmeal
You can keep baked oatmeal stored in the refrigerator for up to a week.
If you don’t plan to eat it before then, I would slice it, wrap into individual pieces and place them in the freezer. Then you can just quickly defrost when needed!
Serving Blueberry Baked Oatmeal
This baked oatmeal is great to eat on it’s own, but you could also serve it with:
- maple syrup/greek yogurt on top
- a slice of Sausage Egg Bake for a balanced breakfast or protein, carbs and fat
- Crock Pot Breakfast Casserole
- Potato Crust Quiche
Storing Blueberry Oatmeal Bake:
Reheating baked oatmeal: This oatmeal is great when microwaved or warmed in a toaster oven.
Storing: I would not store this baked oatmeal at room temp. It likely will get moldy or stale if you don’t refrigerate it.
This baked oatmeal will last in the refrigerator for up to a week.
Freezing: Bake, slice and freeze your oatmeal. You can individually wrap it to make it easier, or allow slices to freeze and then put them in a ziploc bag or container so they don’t stick together. Baked oatmeal will last about 3 months in the freezer.

Good flavor. I did not use almond milk (used lactose free Fair Life milk) and had to cook longer than 40minutes in order for the bake to solidify.
The Clean Eating Couple says
Glad you liked it, Ashley!
Amanda says
Made this today and it smells delicious in my oven! Subbed plantain flour for the collagen and maple syrup for the honey. Can’t wait to eat this!
The Clean Eating Couple says
So glad to hear this Amanda!! Enjoy 🙂
Jamie Schimdt says

Marilyn Sponheimer says
I have not made this yet but do you have to add the Collagen Peptides I do not have any? Can I use something to substitute until I get it OR do you have to add it? It looks healthy and yummy !! Sorry the printing is so small I don’t know how to get the fonts bigger from here. I just noticed that someone used plantain flour instead. Can I use any other flours. Don’t have any plantain flour.
Thank you !
The Clean Eating Couple says
Hi Marilyn – You do not need to use collagen peptides – I actually have removed them from the recipe, as they’re totally optional. There is no plantain flour in this recipe, and I don’t see anyone else has tried that. There’s no flour at all in this recipe and I wouldn’t add any. Hope that helps!
MLN says
Hi! I have a suggestion, if you don’t mind one? Try adding a swoosh of cardamom the next time you make this – cardamom + the spices you have listed are like PB&J! Trust me, I’m a doctor.
… okay, I’m not, but try it anyway. Worth. It. Also, just wondering if I were to leave the coconut oil out entirely (and not substitute for anything), whether it would affect the baking, or anything else, for that matter? Thank you!
The Clean Eating Couple says
Hi! Feel free to add cardamom. Sounds good. I wouldn’t recommend leaving out the oil – it helps to add moisture to the oats. If you try it without it – let me know how it comes out!
Lauran says

I followed this recipe and it turned out great! It was so easy and refrigerated well. I definitely was too excited to cut into it though, and it fell apart a bit but stayed together enough to refrigerate in squares. It still tasted great, regardless!
The Clean Eating Couple says
Glad you liked it, Alena!

I’ve made this many times & it comes out delicious. It freezes well & I’ve had success with several different berry combinations. It makes an easy prep ahead breakfast that’s substantial enough to keep me full until lunchtime.

Can you use frozen blueberries
The Clean Eating Couple says
This is noted above in the recipe: Frozen berries: I haven’t tried this with frozen berries – but I think it would work. I would thaw the berries completely and allow excess liquid to drain off before adding them to the batter.

Sandra B Newell says
Great weekly breakfast prep and a chance for me to take a welcome break from eggs and veggies. I used frozen blueberries and added a little more cook time, just in case.
The Clean Eating Couple says
Thanks, Sandra!
Diane says
LOVED this recipe! Followed the recipe but used half the amount of ginger since I’m not a big fan of that flavor, but might use all of it next time because that hint of finger was soooo good! I enjoyed this for breakfast, but it could also be used for breakfast for dinner meal! So good! ❤️😋
The Clean Eating Couple says
So glad you liked it, Diane! I’m not a huge ginger fan but it does add a nice flavor to the dish!
Jen says
Delicious and easy. I used frozen blueberries, did not defrost, and they worked fine also.
The Clean Eating Couple says
Thanks, Jen! So glad you liked it!
Nancy Guido says
Can you freeze this?
The Clean Eating Couple says
Yes, please read the post. It says: Freezing: Bake, slice and freeze your oatmeal. You can individually wrap it to make it easier, or allow slices to freeze and then put them in a ziploc bag or container so they don’t stick together. Baked oatmeal will last about 3 months in the freezer.
Angela Lee says
Made this today. Wonderful! Add some ground flax and mixed berries. It was delicious. Definitely going to be making again.
Amanda says
Could I add protein powder to the recipe?
The Clean Eating Couple says
I’ve never tried it, sorry! I don’t know how it would affect the recipe. If you try it, let me know!
Ashley says
Such a great make ahead recipe, and so delicious! Planning to add this into the regular breakfast rotation.
Liza says
This looks good but Where are you getting the 18 grams of protein from? Oats/Berries are carbohydrates and 1 egg of 7 grams of protein split 4 ways is only is less than 1 g per slice?
The Clean Eating Couple says
Thanks for pointing this out- looks like there was a typo. I just recalculated it and it’s 7g of protein per serving. Oats do you have 6-8g of protein per 1/4 cup. They’re not just carbs. Feel free to put this in my fitness pal for your own nutrition calculations
