Origin of Overnight Oats

While the concept of overnight oats may seem somewhat new, it’s been around for over one hundred years. Overnight oats were originally created by a Swiss doctor named Maximillian Bircher-Benner.

Originally named Muesli, Dr. Bircher-Benner developed a version of overnight oats, while treating his patients for tuberculosis. His goal was to get them to eat more fruit, which is why most overnight oat recipes are topped with some type of fruit.

Variations

The variations of overnight oats are endless! Regina and I love blueberries, so, that’s what I use but, you can use any type of fruit you’d like.

Don’t be afraid to switch it up and add some variety to your oats! Using different types of fruit is only one variation, you can add different things to your oats to customize them to your preferences.

We normally use honey but you can use peanut butter or syrup, or nothing at all. You can also add chocolate chips, peanut butter chips, granola, nuts, shredded coconut, etc. The list goes on and on. Use your imagination!

Ingredients

Ingredient Notes

Any type of oats (other than instant) will work, however, for the best results, use old-fashioned rolled oats.
What type of milk you use is totally up to you. We prefer to use lactose-free milk because our stomachs don’t agree with lactose. For dairy-free oats, you can use almond or oat milk instead.
For this recipe, I used Garden of Life, Organic Protein. Feel free to use your favorite powder. Nutrition information will change, depending on the powder you choose.
I think I probably use a different kind of granola every time I make overnight oats but the one used in this recipe was banana nut granola.

Recipe Notes

*Most ingredients in this recipe are adjustable, please feel free to change the marked ingredients, including the fruits, to your liking.

Equipment

1 medium-sized mixing bowl
1 rubber spatula, for mixing
Your choice of containers. I used 4 pint-sized mason jars.

How long will they last?

Refrigerated, overnight oats will last about 4-5 days. Be sure to refrigerate them for at least 4 hours. For best results, they should be refrigerated at least overnight to allow the oats to soak up the milk.

In my opinion, they’re best around days 3-4 because they’ve had enough time to soak up all of the milk and the flavors have also had plenty of time to combine.

Be sure to give them a good stir before enjoying them!

Here they are on day 4… YUM!
