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 or whole milk – either will work
- cinnamon, ground ginger, nutmeg – all help to add flavor
- old fashioned oats – we don’t recommend using steel cut or quick cook oats here
- berries
- coconut oil – this helps add moisture to it so the oats don’t get dry
- honey
- an egg
We also like this nonstick bakeware for cooking.
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 any type of berry in this recipe (strawberries, raspberries, blackberries, etc) I’d check out this Chocolate Peanut Butter Baked Oatmeal if you’re looking for something a little more decadent!
Frozen blueberries: 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. If you don’t thaw the berries it might just make the texture a little soggy!
Coconut Oil: You can use olive oil or melted butter.
Honey: You can sub honey for maple syrup or agave. Use the same amount. 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.
Gluten Free: Oats are gluten free, but if you have an allergy 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 walnuts, more chocolate, shredded coconut, fresh fruit or vanilla extract go great in this recipe.
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.
Blended Oats: We love this Blended Baked Oats Recipe!
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.
30-35 minutes in the oven and you’ll have perfectly baked blueberry oatmeal!
You can even double this recipe – just put it in a 9×13 baking dish. You can use a ceramic, glass or metal baking dish. We also like this nonstick bakeware!
Can you prep baked oatmeal with blueberries ahead of time?
Yes, you can totally prep this baked oatmeal ahead of time.
I would recommend baking it ahead of time and then reheating when you’re ready to serve.
If you mix together all ingredients and store in the refrigerator for up to 24 hours before you’re ready to bake, the oats will absorb the liquid and it will not cook correctly.
Storing Blueberry Oatmeal Bake:
Storing: This baked oatmeal will last in the refrigerator for up to 4 days. You can’t store this baked oatmeal at room temperature, it needs to be refrigerated!
Freezing: Baked oatmeal freezes really well! For best results, bake, slice and freeze your oatmeal.
We recommend individually wrapping your portions in plastic wrap or you can slice and freeze in a big freezer safe ziploc bag (but if they’re not individually wrapped they might stick together)
Baked oatmeal will last about 3 months in the freezer.
How to Reheat Baked Oatmeal:
You can eat baked oatmeal cold, but if you want you can also reheat it!
Microwave: This oatmeal is great when microwaved for a minute.
Oven/Toaster Oven: You can also reheat baked oatmeal in a toaster oven or place the baking dish back in the oven if you’d like! I prefer this over the microwave because the edges get crispy
Serving Blueberry Baked Oatmeal
This baked oatmeal is great to eat on it’s own, but you could also serve it with:
- maple syrup or a dollop of 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

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!
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!
Hayley says
Quick and easy breakfast, perfect for making ahead or fresh for guests!! We have made it a few times now and love it!!
The Clean Eating Couple says
So glad you like it, Hayley! Thanks for trying 🙂
Jamie Schimdt says
Delish!!!!! I subbed unsweetened applesauce for the coconut oil bc I was out and it came out fine! Made 6 servings for the week! Thank you!!
The Clean Eating Couple says
So glad you liked it, Jamie! Great idea to substitute!
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 🙂
Ashley Abston says
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!

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.

The Clean Eating Couple says
I’m so glad you like it! I’m totally going to try adding bananas- that sounds amazing!!
Holli Backhaus says
Bananas in it sounds delicious! Do you just add them with the blueberries? I want to do this but wondered when you add them. Thanks!!
The Clean Eating Couple says
You could do that! 🙂 I probably wouldn’t add more than 1/2 a cup of mashed bananas or slices!
