Healthy Baked Oatmeal Ingredients
- Old fashioned oatmeal, regular oats work well too.
- Blueberries, either fresh or frozen.

- Milk, both regular and non-diary work in this recipe.
- Maple sugar, however brown sugar or coconut sugar are great alternatives.
You can easily swap out ingredients in this breakfast casserole. There isn’t a wrong way of enjoying oatmeal for breakfast.
Making Oatmeal Breakfast Casserole Is Easy
It’s as easy as 1-2-3:
- Preheat the oven, and spray a baking dish.
- Mix all the ingredients in a large bowl.
- Pour into the prepared pan and bake.
Honestly, even the kids can do this. Once baked, place in serving bowls, garnish with additional berries and milk and dig in.
Store leftovers in a sealed container in the fridge.
Substitutions
- Dairy and non-diary milk can be used. My new favourite non-dairy milk is oat milk. Almond milk, soy or coconut would be great too.
- Almonds can be swapped out for pecans, walnuts, pistachios, or whatever your favourite nut is.
- Maple sugar is so delicious, but feel free to use brown sugar, coconut sugar or even maple syrup or honey.
- Old fashioned oats are great for any baking recipe. Regular oats are fine. Steel-cut oats will not work well in this casserole.
- Blueberries can be fresh or frozen. You can also use apples, pears, or any other berry you like.
