Matcha Overnight Oats

These matcha overnight oats are just as amazing to eat as they are to look at! A full teaspoon of matcha powder gives these overnight oats a gorgeous color and a delicious flavor.

Top them with some fresh berries and a drizzle of honey and you’ll be in breakfast heaven.

As an added bonus these overnight oats come together in about 5 minutes! They last in the fridge for up to 4 days, so they’re the perfect make ahead breakfast for a busy week.

I usually make a batch of 4 at the beginning of the week so I have one ready to go each morning (on Fridays I like to treat myself to a bagel).

Having a healthy, delicious breakfast each morning helps me start my day on the right foot.

What Exactly is Matcha?

Matcha is made from special green tea leaves that are ground down into an incredibly fine consistency.

The tea leaves are special in a lot of ways but a big part of it is how they’re grown. They’re grown in the shade for the last 3 to 4 weeks before they’re harvested.

Growing these tea leaves in the shade increases the amount of caffeine they contain and intensifies their color.

You can buy matcha powder at most grocery stores in either the tea and coffee section or the international section. I get mine from Whole Foods, but you can also order matcha powder on amazon.

I’m not going to lie, matcha powder is not cheap. The good news is a little goes a long way. I find one little tin makes about 8 batches of these matcha oats.

Getting the Ratio in These Matcha Oats Just Right

Oatmeal can be a divisive topic. Most people prefer their oatmeal one of two ways. Either thick like paste, or thinner and a bit wetter. I personally like my oatmeal a bit “wetter.”

However, that’s not how this recipe is formulated. I created this recipe to make a thicker oatmeal once it comes out of the fridge. This way everyone is happy in the end!

People who like a thick oatmeal can eat it straight out of the fridge and anyone who wants it a bit thinner can add a splash of milk or water.

I find that the proper ratio of liquid to oats can vary. For instance, I love adding chia seeds to my oats because they’re a great source of fiber, omega-3s and protein. But they absorb a ton of moisture!

Usually I stick to a 1:1 ratio of oats to milk, but I use 2/3 of a cup of milk in this recipe because of the chia seeds.

How Far in Advance Do You Need to Make Overnight Oats?

Despite their name, overnight oats don’t actually have to sit in the fridge overnight.

However, they do need a bit of time to soak up the water or milk and soften. If I forget to make my overnight oats ahead of time, I find they only need about 3 hours to soak before they’re ready to go. They’re definitely a bit thinner when they soak for less time though.

Letting them sit overnight not only helps them fully soften, but it also gives the flavors a chance to develop.

Long story short, an overnight soak is ideal but not necessary if you’re short on time.

Can Overnight Oats Be Eaten Warm?

Not everyone can get behind the idea of eating uncooked, cold oats. And I get it, if you haven’t tried overnight oats before it can seem like an odd concept.

But trust me on this one, cold overnight oats are absolutely delicious. They’re such a refreshing breakfast on a warm day!

With that be said, you can eat overnight oats warm. They can be heated just like any other bowl of oatmeal. Pop them into the microwave and heat in 30 second intervals until they’re warm.

Matcha Overnight Oats Ingredients & Substitutions

While I love this recipe for matcha overnight oats just the way it is, I know some of you might not have all these ingredients on hand.

Below are some swaps and substitutions that can be made in this recipe:

  • Rolled Oats – This recipe turns out best with rolled or old-fashioned oats. You can use quick oats if that’s all you have, but you should reduce the amount of water or milk to 1/2 a cup.
  • Chia Seeds – If you don’t have chia seeds, you can omit them from this recipe. They absorb a lot of liquid though, so you will need to reduce the amount of milk to 1/2 cup to get the right consistency.
  • Matcha Powder – Be sure you’re using food-grade matcha powder! Green tea leaves meant to make tea will not work. It’s easy to order online or can be found in most large grocery stores like Whole Foods or Walmart.
  • Brown Sugar – This recipe uses brown sugar, which gives it great flavor! You can also use 2 tsp of honey or any sweetener you like.
  • Greek Yogurt – Greek yogurt adds a wonderful creaminess to these oats along with a lot of protein. However, you can use any yogurt you have or like, or use dairy free yogurt.
  • Berries – These oats turn out best with 1 cup of ripe, juicy berries. I usually add a mixture of blackberries, raspberries, and blueberries, but any berry will work. You can also use frozen fruit.
  • Milk – I prefer making these oats with skim milk but you can also use water or any dairy free milk.

Tips for Making the Best Matcha Overnight Oats

  • Make your oats in a sealable container like a mason jar!
  • Feel free to double this recipe or make multiple jars to last the entire week.
  • Make vegan matcha overnight oats by using dairy free yogurt and milk. Coconut, oat, soy, or almond milk and yogurt all work great!
  • If you like your oatmeal a bit thinner, add a splash of water or your favorite milk before eating.
  • Give your oats a good stir before refrigerating them. This helps the flavors blend together and makes it easier for the chia seeds and oats to absorb the milk.
  • Top your overnight oats with additional fresh berries, a sprinkle of granola and/or a drizzle of honey to take them to the next level.

I was really excited to try this recipe. It was good but I have a note- I used a honey yogurt and almond milk. It was already quite sweet and didn't need the brown sugar. Other than that, no complaints.

Hi Alex,

You can definitely omit the brown sugar to adjust the sweetness to match your palette! I have to admit I have a big sweet tooth, and totally get that not everyone likes things as sweet as me. Thank you for sharing :)
