So, how long can overnight oats stay out of the fridge without becoming a science experiment? The general rule of thumb is that they can be left out for up to 2 hours at room temperature. But, let's be real, who leaves their oats out for that long? It's like leaving a pizza out at a party, it's just not going to end well.
However, if you're planning to eat your oats within a short period, say 30 minutes to an hour, you're probably safe. Just think of it like leaving a coffee on your desk, it's not going to go bad that quickly. But, if you're planning to leave them out for an extended period, it's best to err on the side of caution and stash them in the fridge.

The type of container you use can also play a role in how long your oats can stay out. For example, a glass jar with a tight-fitting lid can help keep your oats fresh for longer than a plastic container with a loose lid. It's like the difference between a Tupperware and a ziplock bag, one is clearly more secure than the other.
