Did you know you can make overnight oatmeal using steel cut oats? My overnight oats recipe is so popular and one that I make for breakfast often by soaking rolled oats with milk. The same principle can be applied here for the steel cut oat version with a few differences that I’ll share below, plus many topping possibilities!

What is steel cut oats?

Steel cut oats are less processed compared to rolled oats. The oat groat (or whole oat) is cut into pieces rather than being pressed and rolled. They have a chewier and nuttier texture and hold their shape once cooked. They don’t get mushy after being cooked, making them ideal for make-ahead breakfasts.

How to make overnight steel cut oats

  • Stir the oats into boiling milk and water.
  • Turn off the heat and cover with a tight fitting lid and leave the pot at room temperature overnight. It’s ready for serving the next morning at room temperature or heated again.

Oatmeal topping ideas

Peanut Butter Banana: In this version, slice some bananas, top it with off with creamy peanut butter and then add crushed peanuts (to enforce that peanut taste). Finish it off with a dash of cinnamon to add some warmth.

Strawberry Nutella: Slice some fresh strawberries to place on top of your oatmeal and add some Nutella and chopped hazelnuts. Finish it off with a drizzle of male syrup or honey.

Caramel Apple: Slice a green apple to add to the steel cut oatmeal, add some chopped pecans for texture and drizzle with caramel sauce. If you don’t have caramel sauce, maple syrup works well. Finish it off with a sprinkle of ground cinnamon or nutmeg.

Chocolate Almond Butter: Add some chopped chocolate, a couple of tablespoons of almond butter and a couple of pitted chopped dates. Finish with a drizzle of honey and coconut flakes if you’d like. When you stir this one together, it looks like chocolate steel cut oatmeal – my kids’ favorite!

Tips for making overnight steel cut oats

  1. Heat water and milk before adding oats. There are methods of making overnight steel cut oatmeal where no heat is applied and the oats just soak the liquid. However, in my experience, the consistency is more creamy and thick when the liquid is heated first.
  2. Don’t skip the salt. Just a little really does make all the difference. It brings out the natural sweetness and nuttiness of the oats and it can taste quite bland if you don’t use it.
  3. Use a mixture of water and milk. I find that this creates that wonderfully creamy texture without adding too many calories or fat. You can use all milk or all water if you prefer.
  4. Heat for a thicker consistency. When you first take a peak in the pot the next morning, you might notice some liquid still in the pot. Stirring it will allow the oats to absorb more of that liquid. But reheating is will help most. Plus it’s already in a pot, so it’s a quick convenience step.

Frequently asked questions

How long should steel cut oats sit overnight to soften?

Steel oats are much tougher than rolled oats, so you need to let them sit in the liquid for at least 8 hours.

Is it safe to leave the oats with milk overnight like that?

Yes, as long as your kitchen temperature is not too hot, it’s completely safe to leave the oats soaking overnight at room temperature, especially since they are covered in a pot with a lid.

How long does it keep?

Steel cut oatmeal will keep well for up to a week in the fridge. In the morning, place the cooled oatmeal into an airtight container and you can reheat portions of it throughout the week. It’s great to batch cook for easy and quick breakfasts.

  1. Made these in Ramadan for sahoor and despite the oats increasing almost three times in size and scaring my dad a tad bit, they were so loved by everyone! They were so creamy and delicious. Everyone added their own toppings of choice and my sister even eat it cold with berries on it!

  2. These are amazingly delicious ideas. I have never done steel cut oatmeal before; I must say that you’ve made me a super fan. I ate every bowl down to the last bite!!

  3. Great way to have steel cut oats ready in morning! I followed your recipe but made 1/2 cups steel cut oat, 1/2 cup oat milk and 1 1/2 water. It was so creamy and delicious the next morning. I just warmed it on stove for few minutes. Thanks!

  4. Hi Yumna! Just wanted to let you know that the prep and cook time in the recipe should be fixed. You have them in hours instead of in minutes 🙂
