Notes
Allowing your baked oatmeal to cool down a little bit helps cook off some extra moisture, which makes the oatmeal easier to slice and serve.
Make sure you are using old fashioned oats. We found that with quick oats the baked oatmeal was still quite wet after it baked.
To store your leftover baked oatmeal, allow it to cool down completely. You can either cover the baking dish with tin foil/ plastic wrap or transfer it to an airtight container.
Other spices you can add to your baked oatmeal include nutmeg and cloves.
