What are Steel Cut Oats?

Steel cut oats, sometimes called coarse oatmeal or Irish oats, are whole grain groats, the inner portion of the oat kernel which has been cut into pieces. They’re golden in colour and look like chopped nuts and are hard and crunchy. When they’re cooked, they look a bit like cooked brown rice and have a chewy texture and nutty flavour.

Health Benefits of Steel Cut Oats

In addition to the macronutrients we talked about above, steel cut oats also contain:

  • powerful antioxidants and polyphenols which may help reduce blood pressure
  • beta-glucan, a type of soluble fiber with that may help to reduce cholesterol, lower blood sugar levels and improve insulin sensitivity and gut health
  • minerals manganese, phosphorus, magnesium, copper, iron and zinc

Steel cut oast are a whole grain and studies have show that eating whole grains tends to extend life expectancy independent of other dietary and lifestyle factors as they reduce the risk of heart disease, type 2 diabetes, obesity and stroke. Whole grains have also been shown to reduce inflammation markers in the blood so much that a habitual whole grain intake is linked to a significantly lower risk of dying from inflammatory diseases.

Steel Cut vs. Rolled Oats

Steel cut oats and rolled oats are very similar in their nutritional profile and how they taste but they differ quite a bit in cooking time and texture. The main difference between them is how they’re manufactured though, steel cut oats being the least processed form of oats. In contrast to steel cut oats, which are simply cut pieces of whole oat groats, rolled oats are flattened which causes the oat to become soft and because of this they’re able to absorb more water and are softer once cooked.

How else do they differ? Let’s take a look.

  • Nutrition. Rolled oats and steel cut oats are almost identical in their protein, carbohydrate, fat, vitamin and mineral content.
  • Glycemic index. Because steel-cut oats are digested more slowly than rolled oats, they have a lower glycemic index. Low glycemic foods help manage blood sugar, decrease the risk of diabetes and help us stay fuller longer.
  • Texture. Since steel cut oats absorb less liquid than rolled oats, they’re much firmer in texture even when cooked. They don’t get as soft and mushy as rolled oats, regardless of how long you cook them. As for taste, they’re very similar but steel cut oats are just a bit nuttier.
  • Cooking time. Steel cut oats take much longer to cook than rolled oats. Cooked on the stovetop, steel cut oats take about 30 minutes to make but I just love them cooked in the oven for a wonderful, soft but chewy texture.

An easy-to-make, delicious and healthy baked oatmeal dish. This is the perfect recipe to add to your weekend food prep so you’ve got a quick and hearty breakfast during the week. Try it topped with berries, a drizzle of almond milk and maple syrup and a spoonful of your favorite nut butter.



  • 1 cup steel-cut oats (176 g)
  • 3 cups almond milk or another plant-based milk of choice
  • 2 bananas, mashed (approx. 220 g)
  • 1 apple, chopped (approx. 150 g)
  • 1 tsp cinnamon
  • 1 tsp vanilla extract
  • 1/2 tsp sea salt


  1. Pre-heat the oven to 350 degrees F.
  2. Place the bananas in a glass baking dish (I used an 8×8 square dish) and mash with a fork until they form a paste.
  3. Add the rest of the ingredients and mix well.
  4. Cover and bake for 45 minutes then remove the cover and bake for 15 more minutes. If you don’t have a lid for your baking dish, you can use a baking tray flipped upside down and placed on top of the dish (that’s what I do).
  5. Enjoy right away or store in the fridge for up to 5 days, enjoying cold or reheating as needed.


These will thicken up as they sit. If reheating later, drizzle with a bit of your favourite non-dairy milk, if you like.

Topping ideas: maple syrup, almond milk, berries, banana, peanut or almond butter, nuts, cacao nibs, coconut or tahini.
