Steel Cut Oats

One of the things that I MUST have during the week is my morning steel cut oats. They take forever to boil on the stovetop but for years I was committed to the ritualistic stirring of the pot for 30 minutes to avoid the pot boiling over leaving an oatmeal mess on the range.

Then, I began cooking Slow Cooker Steel Cut Oatmeal and found it so liberating that I began making gigantic batches of oatmeal to freeze in individual portions for easy breakfasts at the office. It was a game changer, really. And one that I can’t really take credit for since I was inspired by the Trader Joe’s Steel Cut Oatmeal you can find in the freezer section.

But it was so pricey that I knew I could make my own Freezer oatmeal recipe at home using my overnight oatmeal recipe!

Benefits of Steel Cut Oatmeal

Steel cut oats are considered a super food (in my book, anyway) because they are an excellent source of protein, soluble and insoluble fiber and a variety of vitamins and minerals. The benefits of steel cut oats exceed the benefits of rolled oats because of the way they are processed.

Because steel cut oats are minimally processed, and because they contain more fiber and density than other oat varieties, steel cut oats are one of the healthiest grains available to eat. This alone makes Steel Cut Oats a much better choice than quick oats or rolled oats.

How to Make Steel Cut Oats

Making oatmeal in the slow cooker is incredibly easy to do. Just two ingredients, oats and water, are all you need to get started.

  1. Combine the water and oats in a small slow cooker. Add a pinch of salt, if desired.
  2. Cover the slow cooker and cook on low for 8 hours.
  3. Stir in cream and brown sugar, if desired.
  4. Serve immediately or freeze for later.

If you don’t have a slow cooker or just want to cook your steel cut oats on the stovetop you can bring the water to a boil with a pinch of salt. Add the oats to the water and stir. Turn the heat to low and simmer for 40 minutes, stirring occasionally, until the oats are thickened.

We love this programmable slow cooker with auto warm setting by CrockPot! It’s a great way to make dinners easy and keep them warm until you’re ready to eat. We pull this one out at least once a week and the price can’t be beat!

I LOVE to play around with my steel cut oatmeal, too, creating new and improved variations for easy weekday morning breakfasts like this Spiced Coconut Steel Cut Oatmeal.  It’s so great as a base for so many amazing toppings like these candied walnuts.

And this fall inspired Pumpkin Spice Steel Cut Oatmeal is my absolute favorite up until I’ve overdone the Pumpkin Spice which is approximately around the start of December. After that….this Gingerbread Baked Oatmeal is on repeat for the remainder of the year.

Whatever you’re craving in the morning, I’ve got you covered with all the oatmeal recipes. This Bananas Foster Baked Oatmeal is also a huge hit all year long.
