If you’re looking to add one health habit this week, let it be prepping these High-Protein Blueberry Baked Oats. They’re such an easy breakfast to make ahead, and they taste like cake for breakfast. The texture is soft and fluffy, and each portion has 30 g of plant protein, 12 g of fiber, and 10 mg of iron. All you need is one bowl and 5 minutes of prep. I love having a batch ready to go in the fridge for the week, and you can customize the toppings however you like.

High-Protein Blueberry Baked Oats
[ccc_my_favorite_select_button post_id=”” style=””]This easy high-protein baked oats recipe is perfect for meal prep. Packed with 30g of protein per serving, juicy blueberries, and a touch of lemon zest, it’s a nourishing way to start the day.
Ingredients
- 2 small (150 g) ripe bananas
- 2 cups (160 g) rolled oats
- 3 tsp (10 g) chia seeds
- 2 oz (60 g) protein powder - vanilla
- 1.5 tsp (7 g) baking powder
- 1.5 tsp (4 g) ground cinnamon
- 1.5 cups (220 g) fresh blueberries - see notes
- 1.5 tsp (1.5 g) lemon zest
- 2.25 cups (550 ml) dairy-free milk - I used soy
Instructions
- Preheat the oven to 350°F (180°C) fan on.
- Prepare the batter: this recipe yields 3 servings, each prepared in an individual oven-safe container. The ones I used are 600ml / 20oz (15 cm x 15 cm x 6 cm). In each container, place 50g of banana and mash it with a fork until smooth. Evenly divide and add the oats, chia seeds, cinnamon, protein powder, baking powder, blueberries, lemon zest, and milk among the three containers. Stir each well to combine all ingredients. Let the mixtures sit for 10 minutes to allow the chia seeds to bloom and thicken the batter. Optionally, sprinkle some extra blueberries at the top of the batter.
- Bake: Place the containers on a baking sheet for easier handling and bake in the preheated oven on the middle rack for 30 minutes.
- Serve: Once the baked oats are done, remove them from the oven and let them cool slightly. Enjoy hot or cold, as is, or drizzle some yogurt, fresh berries, or maple syrup.
Notes
Berries: If berries are not in season for you, frozen blueberries work fine, just thaw before adding to avoid releasing extra liquid into the batter. Raspberries are a good alternative.

Why I love this recipe (as a nutritionist)

- Iron-rich: 10 mg per serve to support energy and recovery
- Super easy to prep: Just mix, pour, and bake
- Great texture: Like a soft, fluffy cake

Ingredient notes
- Rolled oats: Use whole rolled oats for texture and fiber
- Blueberries: Add flavor and antioxidants, fresh or frozen both work
- Vanilla protein powder: Boosts protein
- Ripe banana: Adds moisture and helps bind without needing eggs
- Dairy-free milk: Any milk works here, but my first choice is always a soy milk fortified with calcium

FAQ
- Is this recipe gluten-free? Yes, it’s naturally gluten-free as long as your oats, and protein powder are certified gluten-free.
- Can I use frozen blueberries? Yes! Just thaw before adding to avoid releasing extra liquid in the batter.
- What protein powder works best? A neutral or vanilla-flavored plant-based powder works best.
- Can I freeze these? Absolutely. Let them cool fully, then freeze in airtight containers. Defrost overnight in the fridge or reheat in the microwave.
- What’s a good topping? We love coconut yogurt with lemon zest, or a drizzle of nut butter if you want even more protein.
- Can I substitute the banana? Yes, apple sauce or puree works well as a banana substitute. Use the same weight (about 150 g) and check the consistency against the video. Readers have used plain sugar-free apple puree with great results.
- Can I leave out the chia seeds? Yes, you can leave out the chia seeds.
- Can I leave out the protein powder? Yes, you can leave out the protein powder. Add a little more oats to compensate for the missing volume.
- Why did my baked oats come out like porridge? This usually depends on container size. If you’ve made it in a larger container instead of three small ones, it will need longer to cook through. Timing varies based on the size of your dish.

Another winning recipe! This recipe is my favourite breakfast go to. I make it ahead and freeze portions so I am ready for breakfast anytime. So healthy and delicious!
I’m so happy you liked it! Great to know they freeze well too 😍
I made this today as an afternoon snack following the recipe exactly and it was delicious. We wanted to top it with yogurt and only had peach yogurt, so we used that and it paired so nicely. This recipe is a keeper.
Ahh I love this. Peach yogurt on top actually sounds super yummy, I never would have thought of that. I am so glad you enjoyed it!
I don’t eat bananas. What can I use as a substitute?
Apple sauce could work 🙂
Hi 😊 I just made this and was wondering are these American measurements?
I didn’t have three small containers so made in one large one . It turned out more like porridge. Is this the consistency it should be. Thankyou 😀
Hi Robbie, they are American measurements, if you’ve made it using a larger container, it will need longer to cook through, timing will vary depending on the size of your container. For example in this recipe which uses a bigger container, I baked them for 45 minutes

Oooh I’m excited to try this one. I will need to replace the banana with apple puree – would you suggest using the same weight?
I would think so, have a look at the consistency in the video and if it looks similar, it should work 💚 Let us know how you go, hope you love it x
The puréed apple instead of banana was yum!! I just used tubs of plain sugar free apple puree and the whole thing was lush. It’s the perfect alternative to banana for me. Love this recipe!
That’s awesome! I’m so happy you enjoyed it!
