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?

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:

  • 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.

Ingredients for Blueberry Baked Oatmeal:

To make blueberry baked oatmeal you’ll need:

There are substitutions listed below. This is a very versatile recipe!

How to make blueberry baked oatmeal:

Making this baked oatmeal couldn’t be easier.

  1. Take all your ingredients
  2. Mix them together
  3. 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 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 this 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 oatmeal for?

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 & Storing Baked Oatmeal:

Serving: This baked oatmeal is great to eat on it’s own, but you could also serve it with maple syrup/greek yogurt on top! I like to pair it with a slice of Sausage Egg Bake for a balanced breakfast or protein, carbs and fat.

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.

    I’m with ya on the spring weather. I’m in NY visiting my family and we woke up to a little snow yesterday too. Definitely a bummer since it’s been so nice for the past couple weeks! Here’s hoping for warm weather very soon!

    Blueberries in oatmeal are my favorite thing in the world! I absolutely agree that overnight oats don’t have that nice stove-top flavor. But, baked oatmeal is wonderful for serving for multiple people or when you’re too lazy to stir and stir!

      Me too, Cassie! They’re SO good in oatmeal. Overnight oats are good if you need something quick – but I’m a big baked oatmeal fan 🙂

    Why does the weather NEVER work out the way we think it will. Today i checked my weather app in Calgary and it said “ICE FOG”
    ummmm ice fog is not a real thing, and definitely should not be happening during Spring.
    Totally into this oatmeal bake tho, it makes me feel a little bit better about the cold haha

    This is one of my favorite recipes that I’ve gotten from you. It’s part of my weekly Sunday meal prep. So easy and so delicious. I’ve made it so many times, I have the recipe memorized.
    I also just made your Mediterranean orzo chicken. So delicious, too.
    Thank you for these easy healthy meals!

    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.

    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

      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!

    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!

    Reply

    • The Clean Eating Couple

      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!

    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!

    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.

    Absolutely delicious! I am in love with this! When I came out of the oven I let it cool for a little bit and then ate some. I was a little nervous that it wouldn’t stay together, but after it being in the fridge overnight it’s beautiful and delicious.

    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! ❤️😋
