What Are Overnight Oats?

The premise behind overnight oats is that you let the oats soak in water, milk, yogurt or a combination overnight, instead of cooking them, and in the morning (or 8 hours later, if you want them for dinner), you can a creamy, delicious oat based snack or meal.

You can eat overnight oats warm if you really feel like it, but they’re meant to be enjoyed cold and that’s how I find they taste the best.

If you’re going to make regular oats on the stove, then just stick to that method instead of going through all the fuss of letting your overnight oats rest and then heating them up anyway.

You only need the following ingredients for this recipe:

  • greek yogurt – I use full fat (this brand), but you could also use your own favorite brand of greek or regular yogurt
  • water – I don’t like the taste of milk in my overnight oats, so I combine water with the greek yogurt for a creamy treat that’s not too tangy
  • chocolate chips – semisweet are preferable, but you can use any kind you have (I LOVE the Ghiradelli ones)
  • vanilla extract – to sweeten the oats, I like to use vanilla extract, but this is optional. You can bulk buy vanilla extract for cheaper here.

Overnight Oats Storage Tips

People like to eat their overnight oats out of different things, including bowls, these classic mason jars, and mugs.

I like to actually transfer my overnight oats into a sloth mug, as then in the morning it’s easy to carry it around with me as I eat out of the mug.

Maybe not the classiest thing ever, but this is “no fuss” kitchen, not “pretending to be fancy when we’re not” kitchen.

How Long Do Overnight Oats Last?

I prefer to eat overnight oats the day after I make them, but you could use them up to 48 hours after first putting them in the fridge.

Substitutions in Chocolate Chip Overnight Oats

If you’re not loving the idea of some of the ingredients in this recipe, here are some substitution ideas.

Swap out the greek yogurt for your own favorite yogurt, or you can use milk instead if you want a thinner texture.

Remember that you should always try to go for a 1:1 ratio of the oats to the liquids, so if you do 1 cup of oats, you need to at least make sure you’re using 1 cup of milk, or at least 1/2 cup milk + 1/2 cup yogurt or similar.

You can leave out the vanilla extract if you want.

Other sweeteners include honey and brown sugar.
