Baked oatmeal is a warm breakfast casserole that is baked! Oatmeal is a more creamy porridge like consistency that is made fresh on the stovetop or microwave enjoyed hot. On the other hand, this is more of a breakfast casserole, that is cut into squares and enjoyed. A totally different way to eat oatmeal for breakfast.
My favorite part? It can be made ahead, refrigerated and reheated for a quick grab-and-go breakfast for the rest of the week.

Make it right away – Bake the oatmeal as soon as you make the batter. Do not let it hang out on the counter (or fridge). This will let the oats absorb the liquid.
