Ingredients You’ll Need

Here’s a quick look at the ingredients you need to make these protein oats. For a full list of ingredients and amounts please head to the full recipe.

protein oatmeal ingredients with labels on them
  • Rolled oats: I recommend rolled oats for this recipe to get the best texture for your protein oatmeal
  • Milk: you can use any milk, dairy or non-dairy, for this recipe
  • Protein powder: I use vanilla whey protein, but you could have fun mixing up flavors
  • Flax seed: the flax seed adds a perfect boost of fiber to make this protein oatmeal even more satiating. If you are not a fan, you can omit these or substitute chia seeds.
  • Sea salt: just a pinch of sea salt or kosher salt helps bring out the sweetness from the protein powder.
  • Fresh fruit, nut butter or nuts and seeds: use any of your favorite toppings to complete your bowl of oatmeal. I like to top mine with some fresh strawberries, blueberries and peanut butter or some jam and sliced almonds

Boost the flavor of this high-protein breakfast by mixing some dried spices like cinnamon or nutmeg in while simmering.

For a coffee to go with your breakfast, make this cold brew or an iced shaken espresso.

How to make Protein Oatmeal

Step 1: Pour water into a small pot with salt and bring to a boil. Pour oats into the pot, stir and simmer 7 minutes. Whisk together milk and protein powder.

Step 2: Pour milk and protein mixture into the pot along with the ground flax seeds, stirring constantly for another 5 minutes. Separate into bowls and serve with your favorite toppings.

Mad’s Expert Tips for the Best Protein Oats 🥣

  • Cook on low heat – to keep your oatmeal from splitting, you want to keep it on low heat and stir constantly after adding the milk.
  • Steel cut oats require more cook time – I recommend rolled oats for the quicker cook time and great texture, but if you have steel cut oats, adjust your cooking time before adding the milk and protein. You’ll likely need 20 minutes of cook time for these oats.
  • Salt is key to the best oatmeal – Make sure you don’t forget the salt when cooking! The oats have so much more flavor when you add a pinch of salt.
  • Serve cold on busy mornings – the best things about this protein oatmeal recipe is that it makes 3 individual servings meaning you can prep it once and save the leftovers to serve chilled another day. If you don’t like cold oatmeal, simply reheat in the microwave or on the stovertop.

I also use the same protein powder in my protein granola recipe, a delicious snack or dessert!

Recipe FAQs

Can I mix protein powder into oats?

Yes! This is my favorite way to make protein oats. I like to whisk it together with milk first, then add it to the oatmeal on the stove.

Do I add the protein right away?

No. You’ll want to add the protein after you cook the oats, otherwise the texture will be very gooey.

How do I get the right consistency in my protein oats?

For the best consistency, pay close attention to your ratio of water to oats, and cook everything on low! Once you add the oats, reduce your heat and make sure it doesn’t go above a simmer.

Storage and Reheating

Once the protein oatmeal is cooled, place it in an airtight container in the fridge for up to a week. You can enjoy leftovers cold or reheat gently on the stovetop.
