Ingredients + Substitutions

• Steel-Cut Oats – Because you can’t make steel-cut baked oatmeal without steel-cut oats. You can swap them for rolled oats if desired, however, I do not recommend using quick-cooking oats or instant oats.
• Milk – To add some protein and cook the oats. The recipe calls for regular milk, but you can use almond milk or coconut milk if desired.
• Egg – To bind the oats and add a bit of protein.
• Butter – To ensure the oats are moist. You can use coconut oil if needed.
• Maple Syrup – To sweeten the oats and add some flavor. Honey and brown sugar will also work.
• Vanilla Extract – To add flavor and fragrance.
• Cinnamon – To further flavor the oats, feel free to omit it if you like.
• Leavening Agents – A mixture of baking powder and salt to ensure the oats are light and fluffy.

How to Make Baked Steel Cut Oats

1. Mix the dry ingredients. In a medium bowl, combine the steel-cut oats, baking powder, salt, and cinnamon.
2. Mix the wet ingredients. In a large bowl, add the butter, maple syrup, egg, vanilla extract, and milk and whisk until well combined.
3. Mix the batter. Add the oat mixture to the milk mixture and stir to combine until a batter forms, then transfer the batter to a greased 9×9 baking dish.
4. Bake the oats. Transfer the baking dish to an oven at 375°F and bake the oats for 45-50 minutes until the middle is set and the sides are golden brown.
5. Serve and enjoy! Once baked, allow the baked steel-cut oatmeal to cool slightly, and then serve it with toppings of your choice.

Serving Suggestions

Add some mix-ins. To boost the flavor content of this baked oatmeal recipe, you can mix in a cup of fruit, nuts, or chocolate chips. I recommend frozen blueberries, frozen raspberries, diced bananas, chopped apples, chopped pecans, chopped walnuts, or a mixture of them.

Serve with protein. These baked oats are a great source of complex carbohydrates and fiber; however, they are low in protein. Serving oatmeal with a source of protein, such as Greek yogurt, skyr, cottage cheese, scrambled eggs, or breakfast sausages, can help to create a balanced meal.

Serve with healthy fats. To ensure your steel-cut oats breakfast is complete with all three macronutrients, you can top them with a source of healthy fats such as a drizzle of almond butter or peanut butter.

Serve with fiber. While the oats contain 5 grams of fiber per slice, serving them with a topping or side of fresh fruit can help to increase the fiber and micronutrient content of the meal.

Add a touch of sweetness. While these baked steel-cut oats do contain some sugar, you can add an extra touch of sweetness by finishing them with a drizzle of pure maple syrup or honey.

Cook Mode Prevent your screen from going dark

Instructions

1. Preheat the oven to 375°F and grease a 9 x 9 baking dish or a similar-sized baking dish with butter.
2. In a medium bowl, add the steel-cut oats, baking powder, salt, and cinnamon, and stir to combine. Set aside.
3. In a large bowl, add the egg and maple syrup and whisk until well combined. Then add the melted butter, vanilla, and milk, and whisk again until combined.
4. Add the dry ingredients to the large bowl of wet ingredients, stir to combine, and then transfer the oat mixture to the greased baking dish. The mixture is going to be very liquidy, but don’t worry, it will absorb the milk in the oven. (Optional: If adding any add-ins, such as fruit, nuts, or chocolate chips, gently mix them in at this time.)
5. Transfer the baking dish to the oven to bake for 45-50 minutes until all of the milk is absorbed, the middle is set, and the sides are golden brown.
6. Once baked, remove the baked oatmeal from the oven and allow to cool for 5-10 minutes to set. Then slice and serve with toppings of your choice.
7. Any leftover steel-cut baked oatmeal can be stored in an airtight container in the fridge for up to 5 days or in the freezer for 3 months.
