Can You Heat Up Overnight Oats?
Yes, you can heat up overnight oats in the microwave or on the stove. Simply transfer the oats to a microwave-safe dish or a pot, add a splash of milk or water if needed, and heat until warmed through. Adjust the heating time according to your preference. The oats may thicken up after being refrigerated overnight, so you may need to add more liquid before reheating.
