High Protein Overnight Oats

These High Protein Overnight Oats are a creamy, make-ahead breakfast that's perfect for busy mornings, meal prep, or post-workout fuel. The oats soften overnight while the Greek yogurt and protein powder create a rich, creamy texture. Fresh berries add natural sweetness, and a sprinkle of high-protein granola provides the perfect crunchy finish.

Ingredients

  • Refrigerate overnight. Add more milk if needed to achieve the desired consistency. Top with granola and berries.

Notes

Mixing and Layering:
The milk and protein powder need to be combined before adding the other ingredients to ensure the powder is fully mixed with the liquid. If the oats are added right away, they absorb some of the liquid needed to mix with the powder, which creates clumps of protein powder.
Protein Powder Differences:
This recipe was tested using Oikos Pro Vanilla Greek Yogurt.
Protein Powder: PEScience Select Protein Powder and Naked Whey Vanilla (see photo #9 for comparison).
The kind of protein powder used may affect how the liquid is absorbed. More milk can be added after stirring the oats once they have absorbed the liquid and thickened overnight.
