It’s just the same oat groats processed a different way than your usual rolled oats — chopped up rather than being rolled — giving them a nuttier, more porridge-friendly goodness. Contrary to what you may have read on the internet, their nutrition and glycemic index is the same as any other unadulterated oats.
The two big distinctives for our family are:
1. They taste really good and go well with a lot of different add-ins, and
2. They take a LONG time to cook.
Forget the microwave. Not gonna happen. You can make “old fashioned” rolled oats in the microwave (3-5 minutes, use a bigger bowl than you think you may need), no problem. And you can make your own healthy version of instant oatmeal for the nuker too.
But steel cut oats have to have time to absorb liquid so they soten up. That’s going to run you 20-45 minutes on the stovetop depending on how many you’re making. So here’s an easier way — we understand it’s the typical Irish way …
Boil four cups of water — to a full rolling bowl.
Add in 1 cup of steel cut oats and return to a bowl.
Take it off the heat, cover, and let it sit all night.
Next morning, warm it up in the same pot, adding in whatever you add to oatmeal.
Could not be easier.
