We have spent countless mornings devouring different bowls of oatmeal and overnight oats, but nothing beats our protein overnight oats. These are not only a delicious, time-saving breakfast option but also a perfect post-workout meal to refuel and recover.
With just one base recipe and three delicious flavor options, this will soon become your go-to oatmeal recipe. Trust us when we say, this is the best protein overnight oat recipe on the internet.
What is in protein overnight oats?
These overnight oats are made with quick-cooking oats, chia seeds, Greek yogurt (for more protein), almond milk, and your favorite protein powder. Remember, the flavor will vary based on what protein powder you use!
Substitues & Variations
Feel free to substitute milk with any plant-based options. The protein powder can be of any type – whey, plant-based, casein, etc. If you’re not a fan of chia seeds, flax seeds are an excellent alternative.
Though we used quick-cooking oats, old-fashioned rolled oats can also be used. The difference is that the old-fashioned oats leave you with chewier (but still delicious) overnight oats.
We’ve also provided three different flavor options in the recipe card. Scroll down to check out the flavor variations of apple cinnamon, chocolate peanut butter, or raspberry almond.
Can I use steel-cut oats instead of rolled oats?
We haven’t tested this recipe with steel-cut oats. Generally, steel cut oats are tougher and would need double the time and more liquid to be used.
Do I need to cook the oats first?
No, the beauty of overnight oats is that they soften and “cook” in the milk overnight.
Store your protein overnight oats in an airtight container in the fridge for up to 5 days. However, we’ve found they taste best when consumed within 2-3 days.
We suggest storing without toppings to keep the overnight oats fresh. Store toppings separately and top right before serving.
