Overnight Oats are the perfect breakfast for a busy week ahead! Make a few jars on the Sunday as part of a meal prep and you have breakfast for the next few mornings. In fact, overnight oatmeal is so easy to make you can whip together a few days worth in about 5 minutes the night before. It’s that easy!

What are overnight oats?

Overnight oats are just what they sound like oats that have been prepared the night before. The base of almost every recipe is 1 part rolled oats, 1 part liquid like milk, almond milk or coconut milk and 1 part yogurt.

Then the fun part… add in the flavour! Fruits, cocoa, maple syrup, honey, chia seeds, flax seeds, hemp hearts, raisins, carrots and on and on. The options are limited only by your imagination and how big your dish is.

Overnight the oats will soften from the moisture and you are left with a tasty porridge that you can eat cold or warm up in the morning.

Overnight oatmeal tips

  • Start with the right oats. The oats you choose will determine the consistency you end up with. Do you like your oats soft or chewy? Steel-cut oats are less processed and therefore take longer to break down which results in chewer oats. While quick oats are highly processed and breakdown quickly resulting in a soft porridge-like texture. I use rolled oats because I like them soft with a little bit of texture to them.
  • Add the toppings at the right time. Some parts of the recipe should be added to rest overnight while others should be added just before eating. Anything like cocoa, peanut butter, sweeteners, seeds and fresh fruits can be added the night before. Ingredients that need to stay firm or crispy like nuts, coconut, dried fruit should be added just before eating or they will get mushy.
  • Grab a few small containers with lids at the Dollar Store. I like to prepare my overnight oats in small containers vs one large bowl. This way if I need to run out of the house I can just grab the oats and a spoon and hustle on! The dollar store usually has lots of small major jars or jam jars with cute lids that work perfectly.
  • Make Lots. One of the best things about overnight oats is that they are convenient so making a few days worth just makes sense. They store well in the fridge in a sealed container for up to a week!

What is skyr?

Skyr is an Icelandic food that has been around for thousands of years and very similar to Greek yogurt. It is known for its very high protein content with an average of 20 g of protein per cup.

While similar to a Greek yogurt it is a bit thicker and according to Icelanders not a yogurt at all but rather a cheese! For more info on Skyr check out this article from Cook’s Illustrated.

  1. Would you describe the finishing product as thin, creamy, or dense-ish. The point being- how would you describe the texture? Also, does it actually taste like cookie batter?

    1. Hi Amy, I would say it is thick and creamy. The longer it sits the denser it gets because of the oatmeal but you can easily thin it out with some more yogurt or almond milk etc. I love the flavour of this recipe and do think it tastes like oatmeal cookie batter but with less butter. Or maybe like if a cinnamon roll and oatmeal cookie had a baby.
