How to Make Baked Oatmeal
This oatmeal breakfast bake is so easy to make. Once you have lined your baking sheet or sprayed it with pan release there are just a few simple steps to follow!

Pop it in the fridge to bake later (covered tightly in plastic wrap) or straight into the oven to enjoy now!
How Long to Bake Oatmeal
How long to bake oatmeal depends on the size of the pan and the thickness of the oatmeal.
This recipe calls to bake for 40 to 45 minutes until the center is set, in a 9×9 pan.
- For a larger pan, bake only about 30 minutes.
- For a loaf sized pan (like a banana bread pan) bake for 50 minutes.
How to Store Baked Oatmeal
Keep baked oatmeal in an airtight container or cover the casserole dish with plastic wrap before storing it in the refrigerator.
Baked oatmeal can even be frozen in squares or slices then thawed the night before for an instant hearty breakfast the next morning!
How to Reheat Baked Oatmeal
- Once oatmeal is thawed, simply reheat it in the microwave!
- Slices of baked oatmeal can be toasted in a dry skillet.
- If baked the night before, reheating the next day is super easy in the microwave, stovetop, or oven!
