Who's ready to cozy up to a warm, baked blueberry oatmeal? I've got the perfect recipe for you to try! I love enjoying oatmeal for breakfast. My healthy blueberry waffles with oatmeal always are a close tie with this baked oatmeal when it comes to choosing a healthy breakfast.
From a nutritional standpoint, oatmeal on its own is an incomplete meal. Many people don't know that they need to balance a healthy breakfast like oatmeal with protein.
Increasing protein at each meal and snack can significantly reduce the amount of food an individual eats. Lack of protein in meals and snacks drives increased hunger and cravings, low energy, mood issues and anxiety. People almost always eat MORE calories throughout the day when they are not getting adequate protein.
My high protein oatmeal recipe is one of my most popular (and delicious) healthy baked oatmeal recipes for weight loss on this website and it inspired this one! Looking for more breakfast ideas without eggs you've got to try my berry flavored protein baked oats and my make ahead chocolate protein oats!
Why You Will Love This Healthy Baked Oatmeal Recipe
- Low Calorie: Calories are not everything when it comes to weight loss (hormones matter too!), but the reality is calories are an important part of the equation. This recipe is low calorie with healthy ingredients that are also BALANCED. The calories are higher than traditional oatmeal in this recipe because of the added protein. A healthy breakfast for average statured individuals is between 350-500 calories.
- Gluten Free: We're using gluten-frene oats to make this oatmeal recipe naturally gluten-free.
- High Protein and High Fiber: The egg whites and Greek yogurt boost the protein making this baked oatmeal recipe much better (macronutrient balanced) for you than regular oatmeal without protein.
- Easy and Versatile: This healthy blueberry baked oatmeal is easy to customize by changing the flavors and takes just minutes to mix up.

Ingredients
Here's what you need to make this yummy high protein baked oatmeal recipe! You will also need a large mixing bowl and an 8-inch by 8-inch baking dish.
- Rolled Oats: You can use steel-cut oats instead, but I find the recipe works best using rolled oats. You can use regular oats instead of gluten-free too.
- Greek Yogurt: I recommend nonfat Greek yogurt as it is high in lean protein while keeping the fat content balanced. You can use dairy-free yogurt in place of Greek yogurt, but try to find one that's about 10-12 grams per serving with no added sugar and low fat. This can be challenging with dairy free yogurts, but they ARE out there if you look!
- Egg Whites: I do not recommend replacing the egg whites with whole eggs because you will reduce the protein content per serving.
- Almond Milk: My favorite but any milk you enjoy can be used in this recipe.
- Cinnamon: Gives the oatmeal that warming spiced flavor and also adds some natural sweetness. You can replace with nutmeg.
- Salt: Balances the flavors but may be omitted if you are concerned with sodium.
- Vanilla Extract: Enhances the natural sweetness of the dish with its warming essence. I don't recommend leaving it out as it will greatly impact the flavor, but almond extract would be a great substitute.
- Blueberries: I used frozen wild blueberries but you can use fresh too.
Variations
- Swap the Fruit: You can use any fresh or frozen fruit in place of the blueberries. I especially love to use a mixture of berries, but peach is mighty tasty too!
- Egg-Free: If you are sensitive to eggs, you can use protein powder in place of the eggs but you will need to increase the milk to balance the wet ingredients. The amount of milk will depend on the protein powder you use.
- Add Some Mix-Ins: Chopped nuts, like almonds, walnuts, or pecans, shredded unsweetened coconut, or pumpkin seeds are some options for adding flavor and crunch.
- Sweeter Flavor: If you like your low calorie baked oats sweeter, you can add a bit of stevia or monkfruit.
How to Make Healthy Baked Oatmeal
Here are the steps for making healthy protein oatmeal in the oven. It's super easy and great for meal prepping a healthy breakfast ahead of time! To get started, prepare an 8-inch by 8-inch baking dish by spraying lightly with cooking spray or by lining it with parchment paper.
Step 1: Combine the dry ingredients. Add the oats, baking powder, salt, and cinnamon to a mixing bowl.
Step 2: Mix the wet ingredients. Add the milk, yogurt, vanilla, egg whites, and blueberries to another mixing bowl. Stir to combine.
Step 3: Combine. Add the dry ingredients to the wet. Stir to mix together.
Step 4: Transfer. Transfer the mixture to your baking dish.
Step 5: Bake. Place the dish in the oven to bake for 25-30 minutes or until the oatmeal is golden brown and set.
Expert Tips
- Store: Transfer your leftovers into airtight containers and store in the refrigerator for up to four days or in the freezer for up to three months. I like to portion them out into individual servings when freezing so I can pull out just what I need for one serving.
- Adjusting the sweetness: This recipe relies on the natural sweetness of the berries, vanilla, and cinnamon. If it's not sweet enough you may want to add a bit of monkfruit sweetener or stevia to sweeten it up.
- Healthy baked oatmeal cups: You can also make oatmeal in a muffin pan or ramekin if you prefer to make these into oatmeal cups. After mixing, evenly disperse the oatmeal in the openings of your pan or dishes you are using. Don't forget to spray them before adding the oatmeal. Bake in the oven, but check after 15 minutes as they cook a bit more quickly since the portions are smaller.
- Serving: I like to serve this up with some more Greek yogurt on top along with more berries or whatever fruit I used in this healthy baked oatmeal recipe.
Recipe FAQs
Yes, of course! This high protein oatmeal recipe is perfect for meal prep! For meal prep, bake the protein oatmeal according to the instructions, then let it cool to room temperature before slicing and storing the refrigerator.
You can also make this the night before and wait to bake it in the morning. Mix it up as directed and transfer it to your baking dish. Store the baking dish with the batter in the refrigerator overnight, remove it from the refrigerator while the oven preheats, and then place it in the oven to bake. It's a good idea to make this no more than one night in advance due to how absorbent oats are.
Reheat your baked protein oatmeal in the microwave or in the oven. If you are reheating in the microwave, place 1-2 slices of the baked oatmeal in the microwave for 60-90 seconds on high, or until the oatmeal is warm. For reheating in the oven, place your baked oatmeal in a baking dish (or you can reheat in the original baking dish) at 350 F for 8-10 minutes. If it's frozen, make sure to thaw it out overnight in the refrigerator before reheating.

What's best way to unthaw/reheat from the freezer? Just a single bar
I would thaw in the refrigerator overnight.
Wow! Made with a combination of peaches and blueberries! Just stopped by to say this is a keeper and thank you! Just loved it !
So glad you enjoyed it! Love the peaches too.
I’m trying to figure out what I did wrong; I followed all the instructions but the bottom was mushy like all the egg and yogurt went to the bottom and cooked separately. The only thing I can think is a used sprouted rolled oats so maybe they didn’t absorb the liquid as much as regular rolled oats would? Thoughts?
Hi Amanda, it sounds like the egg and yogurt were too cold for baking. Separation happens (curdling) when things are too cold and it can't mix properly with the other ingredients. I recommend taking the yogurt and egg out for a while to take the chill off prior to mixing with the other ingredients and baking.
So I substituted almond milk for cashew milk, Greek yogurt for plain whole milk yogurt and 3 egg whites for 2 whole eggs. It came out amazing! I also added a tbsp of maple syrup and it was delicious. My picky 2 year old loved it as well. Thank you!
I doubled the recipe. Next time I would quadruple the fruit. This has no flavor and the only reason it makes you lose weight is that you don't want to eat it.
Did you forget to add the 2 teaspoons of cinnamon? Also, doubling a recipe always yields less flavor and for that reason I never recommend doubling a recipe. This recipe has received multiple 5 star reviews and I've received nothing but positive feedback on it. You are the first who didn't like it. Everyone's tastebuds are different so not every recipe is going to be likable to everyone. I don't think your comment that the only reason it makes you want to lose weight is because you don't want to eat it was appropriate. I truly hope you have a better day.
This high protein oatmeal bake is awesome! I switched out the almond milk for a Premier Vanilla Protein Shake for even more protein. It's like having cake for breakfast! It's a keeper!
I forgot to add milk but it still came out really good
Just a question. It says 4 servings. Is a serving really a 1/4 of the 8x8 pan for 231 calories? It’s so good! Thanks
That is correct! Glad you like it so much. 🙂
Yum!!
Best oatmeal bake. So easy and turns out perfectly every time!
How many grams does a serving have?
If you want the EXACT serving size in grams, then you would weigh the entire dish baked on a food scale in grams then divide by the number of servings (4). The number of grams per serving is equal to what one serving is.
Do you have a version without fruit added? Just wanted to add fruit in top
I haven't tried it with the fruit omitted, but I imagine the recipe will work fine without the blueberries baked in. Please report back and let me know if you try it!
Is the serving size for this correct? 4 servings?
Yes, 4 servings
This is probably the best baked oatmeal I've tried. Been looking for something with more protein and no added sugar. This has a great texture and wasn't dry (finally!). Looking forward to making different variations and freezing for busy mornings. Thank you!
If I wanted to add Protein Powder how much would I add?
It's going to depend on the protein powder as they all wildly vary with consistency. I would add one scoop or 20-30 grams of protein powder, adjust the milk as needed then bake. You may have to experiment a bit to get the right consistency with the protein powder you use.
No sweetener of any kind?
Sweetener is not needed. Cinnamon is naturally sweet and so are blueberries. The protein powder I recommend in this post has stevia already in it so it is sweet as well.
I am a little confused. I do not see protein powder listed in the ingredients or instructions, however you mentioned that the protein powder you use is sweetened. Should it be added? If so how much? Looks tasty!
The recipe is accurate as written. I explain throughout the blog post that the protein in this recipe comes from the greek yogurt and egg whites. I mentioned that quite a few times. Under the substitution section, I mention that you could use protein powder if you wanted to swap one of those ingredients. I think that is why you are confused.
