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.

Complete list of ingredients with amounts and full instructions is located in the recipe card below. This section covers ingredient and substitution considerations.

  • Steel-Cut Oats: This recipe is made specifically for steel-cuts oats. For baked rolled oats, try my Carrot Cake Baked Oatmeal or Easy Banana Baked Oatmeal.
  • Plant-Based Milk: I suggest unsweetened almond or cashew milk but you can use any variety of plant milk you enjoy such as soy milk, oat milk or hemp milk.
  • Banana: The banana adds sweetness without the need for added sugar and helps to thicken the oats. Ripe or slightly over ripe banana works.
  • Apple: For extra flavour, texture and nutrition, try any variety of chopped apple.
  • Flavourings: To enhance the flavour you can add cinnamon, vanilla and a pinch of salt.

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 2: Add the rest of the ingredients and mix well to combine.

Quick Note: For flavour variations, swap the diced apple for peaches or berries. If you’d like to add anything else, such as raisins or cranberries, those can be added now as well.

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 tray flipped upside down and placed on top of the dish.

FAQ

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:

Carrot Cake Baked Oatmeal
Vegan Baked Oatmeal Cups
Easy Banana Baked Oatmeal

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.
