One of the questions that often comes up when it comes to sous vide cooking is whether or not you can overload a machine. The answer, as with most things, is it depends. If you're using an immersion circulator, there's no real limit to how much food you can put in the water bath as long as it all fits comfortably in the pot or container you're using. However, if you're using a countertop machine, you'll want to be careful not to fill the water bath too full or it will overflow. As far as cooking times go, there's no need to worry about overloading your machine. The temperature and cooking times are set so that the food will cook evenly regardless of how much is in the water bath.
