What’s the difference between Steel Cut Oats and Rolled Oats?

Say hello to your new favourite weekday breakfast – overnight steel cut oats!

The difference all lies in how much the oats have been processed.

Quick oats (mostly used for regular oatmeal) are the most processed of the oats, while steel cut oats are the least processed…they’re essentially just chopped up groats! If you want to please your inner nerd and read more check out quick, rolled and steel cut oats!

They have a ton of nutritional benefits and because they’re less processed and have a really amazing chewy texture. The only downside? They take way longer to cook.

How to make overnight steel cut oats

  • Add the water and almond milk to a pot and bring to a boil.
  • Add in the oats and seasoning.
  • Turn off the heat and let the pot of oats sit on the stove or in the fridge overnight.
  • Wake up in the morning and your oats will be ready!

Making steel cut oats in the slow cooker or instant pot

If making this recipe in a slow cooker, add an extra 1 1/2 cups of water and turn on low heating overnight. Be sure to remember to coat the inside with something nonstick beforehand to ensure you aren’t spending all morning scrubbing!

If you are making them in the Instant Pot, combine 1 cup of oats with 1 1/2 cups of water and 1 1/2 cups of almond milk. Cook them quickly with pressure for about 4 minutes, then remove the pressure and allow them to continue cooking on manual for another 20 minutes. I let mine sit for a while because they start to thicken up as they sit!
