You probably click on this post for one of two reasons.

  1. you love steel cut oats
  2. you were like, “wait, whaaat!? overnight steel cut oats!?”

Or maybe it's a combo of the two, but either way, happy your here because today we're talking all things steel cut oats AND we're showing you how to make overnight steel cut oats with a bunch of delicious flavor options.

What are Steel Cut Oats?

Steel cut oats are made from whole oat groats that have been chopped into pieces using a steel mill. That means because the pieces are bigger, they take longer to cook and have a chewier texture.

If you're not sure how to cook steel cut oats, let me quickly cover the basics:

  • In a pot: simmer your steel cut oats in a 2:1 ratio of liquid to oats and cook for a good 20 – 30 minutes until they're no longer crunch
  • In the instant pot: we have a whole post talking about how to cook steel cut oats in the instant pot, so check that out if you have one
  • Overnight: and then we have what we're talking about in today's post!

Can I Make Overnight Oats with Steel Cut Oats?

It's super easy to make overnight oats with steel cut oats, it just takes one extra step than traditional overnight oats.

You'll start by bringing your liquids to a boil, then you'll add in your oats, let it cook for about 30 seconds, then remove it from the heat. Cover your pan and allow it to sit for at least 4 hours, but preferably overnight so the oats get nice and soft.

If they've soaked up more liquid than you want, just stir in a bit of almond milk before you serve it up!

Flavor Ideas for Overnight Oats

Just like other kinds of oatmeal, you can flavor your overnight steel cut oats pretty much any way you'd like. In this style of post, I like to give you some ideas to get you started, but feel free to use any combo of ingredients you'd like!

Best Basic Overnight Oats Recipe

First up, let's chat basic overnight oats. Here's what you'll need:

  • 1 cup almond milk
  • 1 cup water
  • 1 cup oats
  • Sweetener (if desired)

As I said earlier, bring your liquids to a boil, add in your oats, stir them for about 30 seconds, then remove them from the heat. Cover the pot and allow the oats to soak. From there you'll be able to add your flavors!

Peanut Butter Chocolate Chip Overnight Oats

Our first flavor is peanut butter chocolate chip! Use the same formula you've got above and then stir in some peanut butter, cacao nibs and maple syrup. This one reminds me of a Reeses but is a bit more peanut butter forward.

Apple Overnight Overnight Oats

Our second flavor is apple pie. This is such a great combo, especially in the fall! Use your plain recipe again and stir in some chopped apples, maple syrup, and cinnamon. We like topping it with a bit more apples, a sprinkle of cinnamon and sometimes a drizzle of almond butter (or more maple!).

Chunky Monkey Overnight Oats

Our third flavor is “chunky monkey” which is banana, chocolate and walnut. Stir in some mashed banana into your oats, then follow up with chocolate chips and chopped walnuts. Trust me, this combo is SO good!

Vanilla Raspberry

Next, we have a berry-flavored one which is vanilla and raspberry. It's light and great for summer! I like to make the oats vibrant pink by mashing the raspberries and then stirring them into the oats. We'll also add some vanilla extract and maple syrup. I top mine with a dollop of yogurt, a few more raspberries, and another little drizzle of maple syrup.

Mocha

If you want to sneak a little more coffee into your morning, you will love this combo! It's a chocolate coffee base with some maple syrup for sweetness. It's delicious!! And then we finish with a few coffee beans, some cacao nibs, and almond butter.

Mango Overnight Oats

Lastly, our tropical variety! This one combines mango, coconut, honey, and cardamom and is such a fun twist on any other flavor you might expect. You could also use pineapple if you're not a mango fan!

How Long Can I Store Overnight Oats?

What makes overnight oats a perfect breakfast is how meal prep-friendly they are! You can keep your plain overnight oats for up to 6 days in the fridge, and flavored ones last for at least 4. Just be sure to allow your oats to cool completely before putting them in the fridge!
