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.

Ingredient Notes

  • Steel-Cut Oats: This recipe is made specifically for steel-cuts oats.
  • Plant-Based Milk: I suggest unsweetened almond milk or cashew milk but you can use any variety of plant milk you enjoy such as soy milk, oat milk or hemp milk. You can use light coconut milk as well.
  • Banana: Ripe or slightly over ripe banana works.
  • Apple: Use any variety of chopped apple. This can be substituted with other add-ins like berries, nuts, dried fruit or fresh fruit, etc.
  • Flavourings: To enhance the flavour, I like to add cinnamon, vanilla and a pinch of salt.

This list is not complete. Please see the recipe card at the end of the post for the complete ingredient list with measurements and detailed instructions.

Variations & Additions

  • Chia or Flax: Add 2-3 tbsp chia seeds or ground flax seed for healthy fats, fiber and thickening.
  • Sweetening: The recipe has no added sugar and is only sweetened with the banana. For sweeter oats, add 2-3 tbsp brown sugar, maple syrup or coconut sugar. You can also top with sweetener when serving rather than adding to the mixture.
  • Cranberry Coconut: Add up to 1/3 cup each dried cranberries and coconut flakes.
  • Maple Walnut: Add up to 1/2 cup chopped walnuts and 2-3 tbsp maple syrup.
  • Blueberry: Mix in up to 1 cup fresh blueberries before baking.
  • Carrot Cake: Add 2-3 tbsp raisins, 1/2 cup finely grated carrot and 1/2 cup shredded coconut.
  • Spices: For additional spices, try adding ginger, nutmeg, apple pie spice or pumpkin pie spice.
  • Peanut Butter Banana: Add 3 tbsp peanut butter to the mixture. Almond butter also works.
  • Chocolate Chip: Mix in up to 1/2 cup chocolate chips before baking.

Step-by-Step Instructions

Before You Start: Preheat the oven to 350 F and gather all your ingredients and an approximately 8×8-inch baking dish.

Step 1: Add the banana to the baking dish you plan to use and mash it up until you have a chunky paste.

Step 3. Cover the oats and bake for 45 minutes then remove the cover and bake for another 15 minutes.

If you’d like to add a topping, such as a sprinkle of coconut, brown or coconut sugar, slivered almond or chopped pecans or walnuts, add those now. These can also just be added at serving.

Quick Tip: If you don’t have a baking dish with a lid, you can use a baking sheet flipped upside down and placed on top of the dish.

Can I substitute rolled oats for steel cut oats?

Rolled oats wouldn’t be suitable without some adjustments to the recipe. For baked rolled oats recipes, try:

What are the best apples to use?

Really anything works but I like gala, jazz, honeycrisp, Fuji or for a more tart flavour, granny smith.
