Why I ❤ overnight oats

This healthy make-ahead breakfast contains protein and fiber to start your day, and is full of nourishing ingredients such as blueberries, banana, almond milk, Greek yogurt, and more! Overnight oats are one of my fave breakfasts for a few reasons:

  • Built-in nutrition that comes from a smart mix of whole grains, fruit, and protein, helping you stay energized and focused well into the morning without needing a mid-a.m. snack.
  • Meal-prep magic because one quick stir the night before sets you up with a ready-to-go breakfast that holds up beautifully in the fridge for busy weekdays.
  • Effortless mornings thanks to a no-cook, no-stress approach, you can grab breakfast straight from the fridge and get on with your day (even before coffee kicks in!).
  • 100% customizable so you can switch up the fruit, add nuts or seeds, or adjust the sweetness to match your mood, the season, or whatever you have on hand.

While oatmeal is typically eaten warm, this type is eaten cold, straight out of the fridge. It reminds me of an indulgent chilled pudding… but without all the sugar and action-packed with energizing ingredients. Just mix everything together and allow the oats to sit and swell in the refrigerator. 

It takes about 3 hours to set, but because it’s so convenient to prep the night before, we typically let it sit overnight hence the name “overnight oats”. I find it’s a perfect remedy for hectic morning meals. Trust me, you don’t want to miss oat on this. But hey, if you prefer a warm breakfast meal, you can easily heat it up in the microwave right before eating (equally amazing).

Joyful note 

The riper the banana you use, the sweeter it’ll be, and the easier it is to mash. If your banana is firm, you can peel it, slice it up and microwave it for about 20 seconds to soften (it’ll blend more seamlessly into the other ingredients). I like the gentle sweetness from the banana and blueberries without having to add honey or maple syrup. That being said, for a sweeter experience, you’ll want to add 1 to 2 teaspoons of sweetener into the mix.
