Cara’s 5-star review ⭐️ “THESE ARE SO YUMMY! 10/10! I love how it’s protein packed too!”
Sweet And Protein-Packed Breakfast
As a dietitian, these protein baked oats are a staple in my house because they make breakfast easy and keep me full for hours. Here’s why you’ll love them too:
- Packed with protein. Oats are well known for their fiber content, but they’re not exactly packed with protein. This recipe turns oats into a balanced and filling breakfast with extra protein and nutritional balance.
- Perfect for meal prep. Make a batch on Sunday, store the slices in the fridge, and add your favorite toppings each morning for a 5-minute breakfast that actually supports your health.
- Easy to customize. I designed these baked oats with a simple but satisfying vanilla flavor that works well with endless toppings. Add your favorite fruit, nut butter, or yogurt to switch up the flavor each day.
Dietitian tip! 💡 Oats are packed with beta-glucan fiber that may support heart health. Explore more tasty recipes with oats like my oatmeal pumpkin muffins, no-bake trail mix bars, or cookie dough protein balls.
Key Ingredient Notes
- Vanilla whey protein powder: I use the Leanfit Vanilla Whey protein powder in baking because I like the taste and texture, but use what you have and love.
- Greek yogurt: Make sure to use plain yogurt and not vanilla or other sweetened options. This recipe also works with blended cottage cheese instead of yogurt – but I recommend using half the salt if you make this swap.
- Maple syrup: My protein baked oatmeal is entirely sweetened with maple syrup. Swap honey if needed.

How To Make Protein Baked Oatmeal
Step 1: Whisk wet ingredients until smooth.
Step 2: Stir in dry ingredients.
Step 3: Transfer to a parchment-lined baking pan.
Step 4: Bake, cool, and slice!
Tips From My Test Kitchen
- Don’t use too much protein powder. I recommend spooning and levelling your protein powder when measuring to avoid using too much. This will help prevent dry and chalky oats.
- Let them cool before storing. If you pack your baked oats warm, they’ll get a little wet and soggy in the container. Let them completely cool to room temperature first.
PS. I’m committed to sharing the best possible recipes and learning from reader feedback. This recipe has been re-tested and perfected since it was originally posted in 2024.
Common Questions
For a boost of protein, add a scoop of Greek yogurt or nut butter on top. You can also sprinkle with whole nuts or seeds. For extra fiber, sprinkle your baked oatmeal with fresh berries. For a little extra fun and flavor, drizzle with honey, maple syrup, or your favorite jam.
Let your oats completely cool to room temperature. Slice and store in a food container in the fridge or freezer. To freeze, wrap each slice individually in plastic wrap or parchment paper. De-frost each slice in the fridge overnight before serving. To refrigerate, keep slices stored in a food container and eat them right from the fridge. You can also microwave for 20-30 seconds to enjoy warm. Add toppings right before eating.
They’ll stay good in the fridge for up to four days, or the freezer for up to three months.
Yes! Blended cottage cheese and Greek yogurt both work great, and both have been tested. If you’d prefer to use blended cottage cheese, reduce the salt to 1/4 teaspoon.

Protein Baked Oatmeal
Ingredients
- 2 large eggs
- 1 cup low-fat milk, I use 2%
- 1 cup low-fat plain Greek yogurt, I use 2% (blended cottage cheese works too — see notes)
- 2 Tbsp olive oil
- ⅓ cup maple syrup
- 2 tsp vanilla extract
- 2 cups old fashioned oats
- ½ cup vanilla whey protein powder, I use Leanfit Vanilla whey, spooned and levelled
- 1 tsp baking powder
- 1 tsp cinnamon
- ½ tsp salt
Equipment
- 9×9 inch baking pan
Instructions
- Position oven rack to the middle and pre-heat to 350 F. Line a 9×9-inch baking pan with parchment paper and set aside.
- To your large mixing bowl, add eggs, milk, Greek yogurt, olive oil, maple syrup, and vanilla extract. Whisk until smooth.
- To the same bowl, add oats, protein powder, baking powder, cinnamon, and salt. Mix until combined.
- Pour batter into your prepared baking pan and use the back of your spoon/spatula to flatten batter and evenly distribute oats if necessary.
- Bake for 22-27 minutes or until the oats are cooked through. You’ll know they’re done when the tops look set and lightly golden brown.
- Allow oats to cool for a minimum of 10 minutes before slicing. Add toppings and enjoy!
Notes
- If you’d prefer to use blended cottage cheese instead of Greek yogurt, reduce the salt to 1/4 tsp.
- Topping suggestions: nut butter (I like natural, salted peanut butter), fresh berries, extra maple syrup.
I already commented, but wanted to add that I use sugar free maple syrup for the sweetener , in case anyone wanted to know if that works. Works like a charm – if you aren’t opposed to sugar free products once in a while. It helps me to reduce the calories once in a while. 👍🏼
Sharon, thank you so much for sharing this!! So helpful for everyone to know! And love that you paired with chicken sausage — what a great idea. Appreciate your review!
I LOVE this baked oatmeal, and I prep it in repeat! I add a tablespoon of chia seeds and use protein oats for half of the oats to add fiber and boost the protein a bit more. I also add a tablespoon of zero calorie brown sugar. This is heaven, especially paired with berries (more fiber) and chicken sausage (more protein) and drizzled with sugar free maple syrup. Yum!😋
What if I don’t have protein powder? Can I ad more oats instead? Thank you!
I would suggest trying another one of my baked oats recipes if you can — the protein powder is a dry ingredient but it does also add flavor! If not, you could always try adding extra oats, but it hasn’t been tested that way. Hope you enjoy either way!!
Can you substitute Greek yogurt for the cottage cheese? Thank you
Hi Melissa! Yes, you can 🙂
Can I add fruit to the batter BEFORE baking?
Thanks,
Renée
Yes you can! I would limit to about 1 cup of fruit, and if you’re using frozen, make sure it doesn’t defrost before adding to the oats. Hope you enjoy!
I’m wondering if steel cut oats could be substituted? Would you change the amount of oats in the recipe? Thanks!
Unfortunately steel cut oats will not work in this particular recipe. Sorry about that!
This is the easiest recipe for meal prep breakfasts and really give me something to look forward to at the end of a night shift! I have been eating these for over 3 months straight! My colleagues are always jealous and a few have gone and made them for themselves as well! Super packed with protein goodness already, and even better served with Greek Yoghurt and fresh raspberries on the side. Will be a favourite for years to come as my 8 year old now requests for her school lunches as well. Thanks Miranda!
I’m really enjoying this recipe! I’m topping it with berries, peanut butter, and honey. It’s been nice to have breakfast ready to go in the morning. Thank you for sharing this with us.
These are great
These are my new weekday breakfast go to. I’ve modified by adding chia and ground flaxseed to increase the fiber. Eat them heated with blueberries on top. Absolutely delicious!
I’m so glad you liked them. Thanks for the review!!
Hi! How much Chia/flaxseed did you add? Thanks!
A great new way to use oatmeal, super filling and delicious! I definitely had to cook longer in my oven, so as always it will vary. Super easy to prep, will make these again!
Absolutely love this one!!! I’ve prepped it for breakfast three weeks in a row now! So easy and filling.
Yummy , thank you .
So glad you enjoyed them!
This recipe makes the house smell amazing! These baked oats have the potential to be super delicious if not over baked. I know all ovens are different; I did these as the recipe is written at 375° and checked them at 25 mins and they are super overdone, very well browned on top and dry throughout. Not a moist crumb to be found. I would recommend baking them at 350° and checking at 20-25 mins. Will definitely make these again and lower the oven temp and baking time. Thank you for sharing a great idea for meal prep!
I’m so sorry they were overdone! Hope you enjoy next time and thank you for the feedback.
I’m glad you liked it! You might find it sweeter with vanilla protein powder next time – the recipe calls for this because it serves as a sweetener + flavor enhancer here. But regardless, I love that you made it work!
THESE ARE SO YUMMY! 10/10! I love how it’s protein packed too!
I’m so glad you enjoyed them YAY!!
