Wake up to a refreshing and nutritious breakfast with these Lemon Blueberry Overnight Oats! This easy, make-ahead meal is bursting with bright citrus flavor, juicy blueberries, and just the right amount of sweetness. Perfect for busy mornings, these creamy and satisfying oats require just a few simple ingredients and no cooking—simply mix, refrigerate, and enjoy!
Combine all ingredients except the blueberries in an airtight container or 16-ounce jar with a lid. Seal container and shake vigorously for a minute or so until everything is well incorporated and no lumps appear.
Place sealed container in the fridge for 2 hours or ideally overnight to thicken.
Remove from fridge and stir. Taste and adjust sweetness if needed. If your oats are too thick (which may happen if using vegan protein powder), add another tablespoon or two of milk. Add the frozen blueberries and allow at least 5 minutes for the blueberries to thaw before eating. Mixing the frozen blueberries into the oats before they are set may make the oats watery.
Notes
Sweeten this recipe to taste. If using greek yogurt rather than sweetened protein powder, you may want to add 2 tablespoons of maple syrup.
Adding them too early may add unwanted excess moisture to the oats. If I plan on eating them around 10 AM, I like to throw the blueberries in before I leave for work around 8 AM. This way they are softened but still cold! I generally won't mix them in. I leave them on top of the set oats and mix them in right before enjoying.
If your oats are too thick after setting, you can add a tablespoon or two more of milk. If they are a little too thin for your preferences, add another tablespoon of yogurt, protein powder, or chia seeds.
Omitting the greek yogurt/protein powder will make the oats more liquidy.
Sprouted oats are a little more firm, and work best if set overnight.
Storage: Overnight oats can be stored in an airtight container in the fridge for 4-5 days, making them an ideal meal prep option for a busy week. They will continue to thicken over time, but a splash of milk can easily bring them back to the perfect consistency. For the best texture, add the blueberries on top either the night before or the day you plan to enjoy them!
