What are Overnight Oats?

I know you are curious. In essence, overnight oats are your choice of oatmeal soaked in your favorite type of milk, (and it doesn’t have to be dairy milk, you can use almond milk, or other milk if you desire).

It may be sweetened with honey, or maple syrup, and fun toppings can be added such as nuts, fresh fruit, or even ground cinnamon. It takes just moments to prepare, and you have breakfast in the time it takes to grab a spoon.

Best of all there is no cooking required to make or eat overnight oatmeal!

Are overnight oats healthy?

One of the worst-kept secrets is how healthy oatmeal is for you. Here are a few of the benefits of overnight oats!

  • Oats are high in fiber – a half-cup serving packs in 4 grams of fiber. Four grams of fiber is 14% of your daily requirement.
  • Oatmeal is good for your health – the beta-glucan in oatmeal has been shown to reduce cholesterol levels by 5 to 10 percent according to a story in the Journal of Nutrition and Metabolism.
  • Overnight Oats contain biotin – Your hair and nails need biotin. Biotin helps the skin fight chronic skin diseases and is healthy for the brain.

Simple Overnight Oats – Recipe Ingredients

Here’s what you need to make plain overnight oats and a couple of toppings:

  • Oats
  • Milk – you can use a plant-based milk like Almond milk if you like
  • Toppings – I used blueberries and honey.

Let’s take a deeper look into each one of the ingredients:

The Oats

Different oats perform slightly differently. The preferred type of oatmeal is the old-fashioned kind. To make overnight oats, you can use instant oatmeal, rolled oats, or even steel-cut oats. The textures will vary.

  • Instant Oats – these are naturally thin, and these work well if you have never tried making oatmeal this way. The thin flakes absorb the liquid and these tend to be softer than rolled oats.
  • Old Fashioned Rolled Oats – these are perfect for your overnight breakfast, they do absorb the milk but tend to be denser and have a nice texture when you dig into your oatmeal.
  • Steel-cut oats – Since steel-cut oats are as close as you can get to nature, they aren’t rolled and processed like other oatmeal. It takes the liquid longer to penetrate the oatmeal, so you will want to soak this type of oatmeal for longer. Make sure you let these soak for at least 10 hours before enjoying them. They will be super crunchy on day one, but they can be enjoyed for several days after making them.

The Liquid

You can use a variety of milk for this recipe, you can use dairy milk, such as whole, skim, 2%, or fat-free. You could also use non-dairy milk such as almond, cashew, or coconut. You may want to stick with unsweetened so you can control the amount of sweetener.

The Ratio

I like to use half oatmeal and half milk. You can experiment to find out what you will like the best.

The Mix-Ins

Just like your favorite ice cream, you can add whatever you like. Here are some suggestions: Frozen fruit, fresh fruit such as bananas, blueberries, or strawberries work well. You can use a mix in any nut butter. Have some Chia seeds? you can add those too.

You may want to add spices such as cinnamon, nutmeg, cocoa powder, or even matcha. My suggestion would be to pick out add-ins that are already completely hydrated.

You can also add sweeteners, I like to add some fresh local honey, but you can add stevia, sugar, or another one of your favorite sweeteners.

Best Containers for Overnight Oats

I like to use half-pint Mason jars. You can use those, they are washable, they come with lids, and you can reuse them over and over again. Don’t have a handy Mason jar? You can use a bowl, a coffee cup, your favorite Tupperware container, or your favorite plastic container. Just cover the top when placing your oatmeal in the fridge overnight to do its magic.
