Don't diss it until you try it, but this high protein oatmeal recipe is made with egg whites, which gives it a fluffy, almost cake-like texture you wouldn't expect. As a dietitian, a lot of my clients don't like adding protein powder to oatmeal because it can taste gritty or overly sweet and this is the simple solution.

Many of the clients I work with in my online dietetic practice struggle to consume enough protein at breakfast. At the same time, a lot of them don’t love relying on protein powders. That’s why this egg white high protein oatmeal has become such a popular solution.
The best part? You genuinely can't taste the eggs at all. The key is whisking constantly as you add them, which creates that signature fluffy, creamy consistency that's honestly better than regular oatmeal.

Why This Recipe Is Good for You (Nutrition Highlights)
- High in protein: Each bowl has around 21 grams of protein primarily from the egg whites (about 10 grams) and the milk (about 8 grams), with the oats contributing the remaining 3 grams. This combination of protein sources provides all the essential amino acids your body needs.
- Rich in fiber: Oats are packed with beta-glucan, a fiber that helps lower cholesterol and keeps digestion steady.
- Balanced blood sugar: Oats on their own provide mainly carbohydrates, but when we combine them with egg whites and milk we add protein and fat leading to steadier blood sugar levels and a more gradual release of energy.
- Calcium: I use dairy milk in this recipe because it makes the oats creamy and adds calcium at the same time. Calcium is key for bone health, and protein helps support strong bones too, so you’re getting both in one bowl. For women especially, getting enough calcium matters, as bone density naturally declines with age and after menopause.
The best part? You don’t need protein powders. Just simple ingredients doing exactly what you want them to do.
Key Ingredients
The complete ingredient list with measurements can be found in the recipe card below.
- Old-fashioned rolled oats: Also called porridge oats in Ireland. Use rolled oats rather than steel-cut oats for this recipe, as steel-cut oats take much longer to cook. Quick oats will work too, but they may result in a slightly mushier texture.
- Milk: I used 2% dairy milk for testing, but you can use any milk you prefer. For the highest protein content, stick with dairy milk or soy milk. Almond milk, oat milk, and other plant-based milks will work but will provide less protein overall. If you want to reduce calories, you can use half water and half milk, though this will also reduce the protein content slightly.
- Liquid egg whites: I used liquid egg whites straight from the carton because they're convenient, pourable, and easy to measure. This equates to about 2 medium egg whites. If you prefer to separate fresh eggs, that works perfectly too but make sure to whisk them well before adding to the oats.
- Vanilla essence: For a little extra flavor.
- Cinnamon (optional): but highly recommended as it adds warmth without any added sugar. It also has potential benefits for blood sugar regulation.
- Maple syrup or honey (optional): If you like your oatmeal on the sweeter side, a drizzle of maple syrup or honey after cooking works well. You could also use mashed banana or applesauce for natural sweetness.
Dietary Substitutions
Gluten-free: Use certified gluten-free oats to make this recipe suitable for those avoiding gluten. Regular oats are naturally gluten-free but are often cross-contaminated during processing.
Dairy-free: Swap the dairy milk for soy milk (for similar protein content) or any other plant-based milk you enjoy. Keep in mind that almond milk, oat milk, and coconut milk are lower in protein than dairy or soy milk, so the nutritional content of the recipe will change significantly.
Vegan: Unfortunately, this recipe relies on egg whites, so it's not easily adaptable to be vegan. For a high-protein vegan oatmeal option, try my High Protein Overnight Oats Recipe and use a plant-based protein powder with a plant milk.
Want to make it...
- Higher in protein? Add an extra egg white or add some protein powder. Add the protein after the oatmeal has cooked and let it cool for a few minutes first. If you add protein powder in to very hot oats it will curdle and go gritty. You can also get savvy with your toppings and add things like Greek yogurt, hemp hearts or peanut butter.
- Lower in calories? Sub the milk for water or ½ water ½ milk.
Recipe Variations
You can easily make this recipe your own by adding different toppings. I actually recommend switching them up regularly so you get more variety in your diet.
You can also mix a few ingredients directly into the oatmeal to change up the flavor and keep things interesting.
Mix-in ideas: (add when cooking)
- Grated carrot or courgette
- Mashed banana
- Apple sauce
- Pumpkin spice, nutmeg, ginger or apple pie spice
- Cocoa powder, chocolate chips, peanut butter (mix in at the end)
- Around Christmas, a tablespoon of Baileys Irish Cream Liqueur added at the end (not for kids!).
Topping ideas:
- Air fryer apples, berries, frozen berries, chopped bananas or kiwi slices
- Desiccated coconut
- Chopped walnuts, sliced almonds or any other nuts or seeds.
How To Make This High Protein Oatmeal
Below are the simple steps for how to make this recipe with visuals I hope are helpful! Don't forget to check out the recipe card at the bottom for the full recipe.
In a small pot, combine the oats, milk, water, cinnamon (optional), vanilla, and salt. Cook over medium heat for 6-8 minutes, stirring occasionally, until most of the liquid has been absorbed and the oats are tender.
Stir in the egg whites, whisking constantly, until the mixture has fluffed up and the eggs are fully cooked, about 2-4 minutes more. The constant whisking is key as it keeps the eggs from scrambling and creates thick, fluffy oats.
Dish up into a bowl and add your favorite toppings. I love mine with fresh kiwi, chia seeds, Greek yogurt, and a drizzle of nut butter & maple syrup.
Expert Tips for Making This Recipe
Don't skip the whisking: When you add the egg whites, you need to whisk constantly. This is what creates the fluffy, creamy texture and prevents the eggs from scrambling into chunks.
Adjust consistency as needed: If your oatmeal becomes too thick after adding the egg whites, simply stir in a splash more milk or water until you reach your preferred consistency.
Use a larger pot than you think you need: The oatmeal expands quite a bit as it cooks, especially once you add the egg whites and whisk them in. Using a pot that's larger than you think you need will prevent overflow.
Storage
These oats are best enjoyed fresh as the fluffy texture is at its peak when it's warm and freshly made.
If you do have leftovers or want to make a double batch for meal prep, you can store the cooked oatmeal in an airtight container in the refrigerator for up to 3 days. The texture will become denser as it cools and sits.
To reheat, transfer to a microwave-safe bowl and add a splash of milk or water to loosen it up. Microwave on high for 1-2 minutes, stirring halfway through. You can also reheat on the stovetop over low heat, stirring frequently and adding liquid as needed.
Freezer: I don't recommend freezing this oatmeal.
FAQS
Yes! You can use 1 whole egg in place of the 70g (⅓ cup) liquid egg whites. Whisk it well before adding it to the oats, then whisk constantly as it cooks. Using a whole egg will add healthy fats, and nutrients like vitamin D and choline, though it will also increase the calories slightly.
Yes they are the. In the US they are called old fashioned or rolled oats whereas in Ireland they are typically known as porridge oats.
Yes. First microwave the oats, milk, water, and spices in a large bowl for 2-3 minutes (length will vary depending on microwave power), until almost fully cooked. Then whisk in the egg whites and microwave for another 30-60 seconds, whisking every 20 seconds until the eggs are cooked through.
No! As long as you whisk constantly when adding the egg whites, they incorporate smoothly into the oats and you won't taste them at all. The egg whites simply make the oatmeal fluffier while adding protein without affecting the flavor.
This happens if you don't whisk constantly when adding the egg whites. The key is to stir or whisk vigorously and continuously as you pour in the egg whites and for the 2-4 minutes they cook. This incorporates them smoothly into the oats rather than allowing them to scramble into chunks.
