Recipe Ingredients
This matcha oatmeal recipe requires just a handful of simple ingredients. We will need the following:
- steel cut oats – I prefer steel cut oats for their chewy texture, but you have the option to use old-fashioned rolled oats or quick oats for a creamy texture. Make sure to use Certified gluten-free oats for a gluten-free recipe.
- chia seeds – for extra fiber, nutrients, and all those healthy fats including omega-3’s.
- protein powder – plant based vanilla protein powder gives it that extra sweetness without sugar. You can also add a dash of vanilla extract, too. There is no added sugar in this recipe, because the protein powder I typically use is sweetened. If you’re looking for a little sweeter flavor, I suggest natural sweeteners like pure maple syrup or coconut brown sugar.
- matcha green tea powder – look for matcha in the tea and coffee aisle or international food aisle of most grocery stores. You can buy it from Whole Foods or Walmart, or even order matcha powder on Amazon. We want culinary grade matcha for all our matcha adventures in the kitchen. Green tea leaves meant to make tea will not work here. You can also use latte grade match if that’s what you have on hand.
- plant-based yogurt – Siggi’s non-dairy yogurt is delicious in this recipe. You can also use regular yogurt or Greek yogurt if not vegan.
- plant-based milk of choice – use your favorite milk such as oat milk, unsweetened almond milk, cashew milk, soy milk, or coconut milk.
- fun toppings – I love finishing off each bowl of oats with blueberries, fresh fruit, crunchy granola, coconut, and nut butter to take it to the next level.

Step-By-Step Instructions

Mix Oatmeal Mixture
In a 16 oz mason jar or mixing bowl, mix together steel cut oats, chia seeds, vanilla protein powder, matcha tea powder, yogurt, and milk until combined. You can also seal the jar and shake.
Soak
Allow the matcha oats to thicken overnight, or at least 4 hours, until the liquid is absorbed.
Check for desired thickness the next morning. If the mixture is too thick, stir in a couple tablespoons of milk.
Finish with Toppings
When ready to enjoy, add your favorite toppings like coconut flakes, fresh berries, banana slices, granola, and nut butter.

Matcha Health Benefits
What’s so special about matcha is that it is a traditional Japanese green tea that is grown in the shade and comes with many health benefits. In its purest form, matcha is green tea leaves that have been stone ground to a fine powder and used in various drinks and recipes, such as the famous matcha latte. A few of its noteworthy health benefits include:
- Cancer Prevention: Matcha contains antioxidants called catechins, which are not found in other foods. The catechin found in green tea, EGCg (epigallocatechin gallate) provides cancer-fighting properties. EGCg and other catechins counteract the effects of dangerous free radicals coming from chemicals, radiation, UV rays, which can all lead to cell and DNA damage.
- Aids in Weight Loss: I don’t want this benefit to be held with too much high regard, but there is research shown that consuming matcha can help boost metabolism and burn fat.
- Lowers LDL “Bad” Cholesterol: The catechin found in green tea, EGCg, also aids in lowering cholesterol levels.
- Rich in L-Theanine: L-theanine is an amino acid only found in tea and matcha may contain up to 5x more of this amino acid than common black and green teas. The beauty of l-theanine is that it helps to promote concentration and clarity of mind without the jitteriness, like you may get from coffee.

Enjoy Cold or Warm
Green tea oatmeal is a delicious breakfast that can double as a healthy afternoon snack. It’s a healthy grab-and-go breakfast that you can meal prep in individual containers at the beginning of the week.
Enjoy Warm: If you are not a fan of cold oats, feel free to microwave a bowl of matcha oats in a microwave-safe bowl in 30-second intervals until warm.
How to Store
Leftover overnight oats will keep in the same mason jar or airtight container in the fridge for up to 3 days.
The mixture will thicken, so feel free to add a splash of milk to bring it back to the original consistency.
