Do oatmeal change texture when reheated?

Yes, oatmeal absorbs the liquid it is placed in, be it water or milk. As it absorbs the moisture, it changes its texture.

This is why, while reheating you should add milk or water while you bring your porridge to boil.

Can you prepare oatmeal in advance?

Yes, you can. There are a couple of ways to prepare your oatmeal in advance and reheat it later on. Whether you have quick fix oatmeal or the old fashioned porridge, you can make it ahead of time.

Take your desired amount of oatmeal and soak it in a liquid such as milk (if you intend to eat it the next morning) or water. You can put this in the refrigerator overnight and take it out in the morning and reheat it in the microwave or the stove. Soaking reduces the cooking time.

You can also prepare it in its entirety and put it in the refrigerator. You can make a huge batch for the entire week and divide it into portions or keep it in one container together, whichever option seems more feasible for you.

Remember to allow your oatmeal to cool down before you put it in the refrigerator. If you are making it in advance for the entire week, it is better to refrain from soaking it. Cook it completely. Another thing to keep in mind is to never leave it out on the countertop overnight because that will increase the risk of bacterial contamination. Even if you have a very early morning, keep it in the refrigerator.
