What are Overnight Oats?
At its core, Overnight Oats are basically a no-cook method of making oatmeal. Instead cooking oatmeal the traditional way, Overnight Oats are made by soaking old-fashioned rolled oats in liquid, most commonly milk, in the refrigerator overnight. This allows the oats to slowly soften up over time to produce a thick and delicious texture.
What makes them great is you can customize them with all sorts of ingredients and toppings for some fun and delicious flavours, and they're perfect for breakfast meal prep because of how quick and easy they are to make.
Ingredients
Please scroll down to the recipe card below for exact quantities and measurements.

- Rolled oats - make sure to use old-fashioned rolled oats, and not steel cut, quick or instant oats.
- Unsweetened almond milk - you can also use coconut milk for a more tropical flavour, or any other milk of your choice.
- Greek yogurt - any kind of yogurt will do. I always recommend adding yogurt to overnight oats for extra creaminess.
- Chia seeds - when soaked in water, they expand and gelatinize - adding thickness and texture. Chia seeds are also a nutrient-packed superfood!
- Maple syrup - I prefer maple syrup, but you can use any kind of sweetener you like, such as honey or agave nectar.
- Pineapple chunks - I like using canned pineapple because they are softer and sweeter than fresh, but you can use fresh as well if you like.
- Coconut flakes - to further add to the delicious tropical taste!
- Chopped walnuts - I like adding in a few nuts for added crunch and texture, but you can use whatever nuts or seeds you like. Sliced almonds work great here!
Instructions

STEP 1: First, cut pineapples into small chunks. Then, in a mason jar (or other sealable container), combine oats, milk, yogurt, chia seeds, maple syrup, pineapple chunks, and coconut flakes. Give it a good mix, snap on a lid, and refrigerate overnight (or 2-3 hours at a minimum).

STEP 2: Take it out of the fridge, and as toppings, feel free to add additional pineapple chunks and coconut flakes. Top it off with some chopped walnuts, and enjoy!

How to Store
Store them in an air-tight container for up to 5 days in the fridge. I like to use these 16-ounce (473 ml) wide-mouth mason jars, with a large opening that makes it easier to clean and stir ingredients in.
Toasty's Tips
- Use coconut milk, or coconut extract (if using regular or almond milk), and/or a splash of pineapple juice to really enhance the tropical flavour!
- Batch prep several servings at a time in a large mixing bowl by multiplying the ingredients while keeping the same ingredient ratios.
- You can add peach or mango chunks to add some more tropical variety.
- Add a pinch of salt and a splash of vanilla extract to further amp up the flavours.
FAQ
What to do if my overnight oats are too thick?
If your overnight oats turn out too thick after refrigerating, you can add a splash of milk to thin it out.
Can I mix in protein powder?
Absolutely! I recommend using unflavoured and unsweetened protein powder so that it doesn't interfere with the natural flavours and sweeteners in this recipe. Just keep in mind that you'll need to add milk in order to offset the dryness that the powder adds.
