What kind of oats are best for baked oatmeal?

Old-fashioned rolled oats are the way to go here! They soften as they sit overnight but still have enough texture to keep the oatmeal from turning mushy. Quick-cooking oats can make it a little too soft, while steel-cut oats need more liquid and extra cooking time. Save those for another recipe!

How long does make-ahead apple-cinnamon baked oatmeal last in the fridge?

Leftovers will keep, covered or in an airtight container, for up to 4 days in the refrigerator. Reheat individual portions in the microwave or pop the whole dish in a 325-degree Fahrenheit oven until the oatmeal is heated through.

Can you freeze make-ahead apple-cinnamon baked oatmeal?

Yes! The baked oatmeal can be frozen for up to 3 months. You can freeze the whole batch together or divide it into individual portions. Let the oatmeal thaw in the fridge overnight before reheating.
