How to make baked oatmeal in the microwave

You can easily make baked oatmeal in the microwave

Simply prepare the baked oatmeal overnight, as directed. The next morning, double check the oats aren’t crumbly. If they are, add a little extra milk, just to keep the batter moist. Microwave for 1-2 minutes, or until just cooked. 

How to store baked oatmeal 

If you plan on eating the baked oatmeal the same day it is made, it can be kept at room temperature. 

For consumption at a later date, baked oatmeal needs to be refrigerated. Cover in a sealed container or saran wrap, and it will last for up to a week.

Can you freeze baked oatmeal? 

Baked oatmeal is perfect to freeze for later! 

Simply allow the baked oatmeal to cool completely, and then wrap in parchment paper. It will keep well for up to 2 months.

To reheat, allow to thaw overnight and heat in the microwave or enjoy at room temperature.

  2. Hello Arman,
    Thank you for all these great recipes. Your book stays on our counter top for reference every day now.
    Quick question, would there be a suitable substitute for the liquid stevia?

    1. Hello! Thank you for your sweet words 🙂 For liquid stevia (for this recipe specifically), you can add 1-2 tablespoons of syrup (depending on your sweetness desire level).

      You could also use a granulated sweetener, but may need to add a tablespoon or two of milk to smoothen up.

  3. Made this today. It was very good. I replaced the stevia liquid with 1 tbsp of date syrup and added some crushed walnuts. Thank you for sharing your recipe!
