Can You Make Overnight Oats with Steel Cut Oats?
Yes. And it only requires a few minutes of hands-on prep time (yay!)
In this post, I will share how to make overnight oats with steel cut oats including all my tips and tricks for making the best overnight steel cut oats possible.
Steel Cut vs. Rolled Oats
Steel cut (Irish) oats are made by chopping whole oat groats into smaller pieces. Steel-cut oats are neither precooked, pressed, nor rolled which means they take longer to cook and have a chewier texture.
Rolled oats, on the other hand, are made by steaming whole oat groats and then rolling them to make large, thin, flaky oats. Rolled Oats cook faster and have a softer texture, making them great for baking.
How to Make Overnight Steel Cut Oats
Bring water to a boil in a small pot. Stir in the oats and salt and mix well. Right away you’ll notice the tough oats start to absorb the boiled water. Cover and cool completely before placing in the refrigerator overnight.
In the morning, cook the oat mixture over medium heat for 5 minutes with an additional cup of water, or milk (for even creamier oats).
Stir often and cook until desired consistency and texture are reached.
Liquid to Oats Cooking Ratio
As a general rule, whenever you make overnight steel cut oats you will need 2:1 liquid to oats cooking ratio. So, for every 1 cup of steel cut oats, plan on 2 cups of liquid.
Toppings and Mix-Ins
This is a perfect base recipe. Enjoy plain and simple, or add your favorite toppings and mix-ins to make it your own.

- Honey, maple syrup, or granulated sugar or brown sugar

Helpful Tips and Tricks
- Easily prepare a big batch of these overnight steel cut oats by doubling, tripling, or quadrupling the recipe. Just follow the 2:1 liquid to oats ratio. Keep the leftovers stored in an airtight container in the refrigerator or divide between smaller jars.
- Leftover overnight oatmeal made with steel cut oats will last for up to 5 days in the refrigerator.
- The oats will have a chewier texture on day one, and progressively get softer and more tender as the days go on.
- You may reheat it on the stovetop or in the microwave. To reheat on the stovetop, place pot with the oats over medium heat. Slowly stir in water or milk until desired consistency is reached and it’s heated through. To reheat in the microwave, place desired portion in a microwave-safe bowl with a few tablespoons of milk or water. Heat on high heat at 15-second intervals until warmed through.
- To freeze leftover overnight steel cut oatmeal, allow oats to soak for at least 8 hours before transferring to smaller, air-tight containers. Transfer to the freezer. Defrost in the refrigerator.
