- Maple sugar, however brown sugar or coconut sugar are great alternatives.

Baked Oatmeal Breakfast Casserole
It’s as easy as 1-2-3! Full instructions are in the recipe card.
- 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.
Suggestions / Recipe Tips
- 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.
Yes, baked oats are nutritious and filling. This recipe is like eating a healthy cake for breakfast.
This is the perfect breakfast recipe for reheating. I like to make lots so we can reheat on busy weekdays. Just pop a bowl in the microwave for a minute or so. Breakfast is ready.
Incorporating oatmeal into recipes is so easy. Give these a try:
- No-Bake Granola Bars are perfect for lunch boxes, snacking, or eating on the run.
- Granola Dust is a great topping for yogurt.
- Chewy Granola Bars are soft and filled with lots of nutritious ingredients.
- Trail Mix Bites are fun to make. These are grandkid approved.
Of course, we cannot resist chewy oatmeal cookies, or apple muffins with oatmeal.
