You can prepare several jars at once for an easy meal prep breakfast. Keep them refrigerated and enjoy throughout the week.

Customize your toppings

Try different combinations of berries, nuts, seeds and cinnamon to create your own version of this easy overnight oats recipe.

How Long Do Overnight Oats Last?

When stored properly in a covered container in the refrigerator, these overnight oats can generally be kept for up to 4 days.

For the best texture, add crunchy toppings such as nuts or granola shortly before eating.
