This heat. I cannot handle this heat!  I love cooking and hanging out in the kitchen and all, but not when I feel like I am about to melt into the floor!

 Oatmeal is typically my family’s go-to, easy, no-thinking-required healthy breakfast…but not when it is 80+ degrees before sunrise! On those mornings, we require something hearty, but that will not add to our risk of overheating. Cue the Overnight Oats!

If I know a hot day is coming, I will make a batch of overnight oats the night before while I am packing lunches.  It literally takes minutes to throw the ingredients into a mason jar or whatever container is handy, give them a little mix, and it throw in the fridge. It then “cooks” overnight in the fridge and in the morning, breakfast is done and waiting for you to gobble up.  

Perfection!

I know some people get a little weirded out by the idea of cold oats, but if you can go into this tastebud experience with an open mind and palate, you might just find another breakfast to add to your recipe box to make life a little easier (and healthier).

There are many, many, MANY versions of overnight oats out there. Like salad or a smoothie, you can add pretty much whatever you want into the mix.  This is my favorite, tried-and-true recipe that I have made (and will continue to make *le sigh*) frequently during the dog days of summer.

** Yep! I totally add veggies into my overnight oats too! They work great for boosting flavor AND nutrients! My advice is to start with a little added veggie in your overnight oats and then add more as you find what flavors you like!

Can I eat overnight oats cold? Or do I warm them up first?

You do you.
The beauty of overnight oats is that they CAN be enjoyed cold (hence, no cooking!). but some people really struggle with the idea of cold oats. So if you prefer, warm them up on the stove or in the microwave for a couple minutes and enjoy them warm.

What is the texture like?

The oats soak overnight in liquid and become nice and soft. I find it has the texture similar al dente cooked oats.

Can I use steel cut oats in instead of rolled oats in this recipe?

Nope. Steel cut oats take a lot more liquid to soften .Swapping them for your rolled oats will leave you with hard oats in the morning. But, steel cut oats do great in the slow cooker or Instant Pot!
