What the Heck are Overnight Oats?

People who haven’t heard of overnight oats are often confused as to the difference between these types of oats and the types of oats you eat in the morning after microwaving or putting on the stove.

With overnight oats, you’re using the same oat base, but there is no heat involved, and the fridge does all of the work.

Overnight, the oats absorb the water or liquid you’ve added, and in the morning you get a creamy, cold breakfast that many find preferable to regular old oatmeal.

If you really want to eat overnight oats warm, you can heat them up, but they’re designed to be eaten cold straight out of the fridge.

  • water – easy! Straight from the tap!
  • greek yogurt – I use full fat greek yogurt like this in these recipes, but you can use your own favorite kind
  • lemon – for getting the fresh lemon juice into our oats
  • rolled oats – the star of the show! Use rolled or steel cut like these, not instant oats as it can be gummy.
  • chia seeds – for some extra protein, omega 3, and color. I prefer this brand.

Substitutions

The fantastic thing about overnight oats is that they are so, so easy to customize.

Seriously, you can switch around so many of the ingredients besides the actual oats to fit your lifestyle.

Some examples would be switching out the water for milk if you want an even creamier and tangy flavor.

You could leave out the yogurt altogether and just use an extra 1/4 cup of water.

You could use your own favorite type of yogurt instead of Greek yogurt.

You could leave out the honey or add more, or use vanilla extract instead of honey as a sweetener.

The basic thing to remember is that you want to keep a 1:1 ratio between the oats and the liquid or runny ingredients, so you don’t want to use 1/2 cup of oats and just 1/4 cup of water, but everything else is fair game.

Obviously making changes will impact the final taste and consistency, but that’s part of the fun in determining how you like your overnight oats because we don’t all enjoy the same type of textures and flavors.

Can I Use Lemon Juice from a Bottle?

If you don’t have fresh lemons, you can absolutely use lemon juice from a bottle like this.

You’ll want about 3 tablespoons of lemon juice instead of the juice from one lemon.

Storage Tips

Storing lemon overnight oats in a jar is super simple – it should be left in the fridge.

I’ve enjoyed overnight oats for up to 3 days after making, though they are best eaten the first day after making.

Make sure you have either a lid on the container they are in or saran wrap for food safety.

What to Serve with Lemon Overnight Oats

Overnight oats are prepared in a single serving in this recipe, though you can double or triple it if you’re trying to feed the whole family.

The oats themselves are the main event for breakfast – they’re super filling, so you shouldn’t need to add more with them.

If you do want some extra substance, I like to pair them with a fruit like a grapefruit for some color and more refreshing taste, or go the opposite and have a warm pastry or toast with the cold overnight oats for the contrasting experiences.

You can also make other types of overnight oats, such as:

and so many more options – get creative!
