I think you’d need to at least triple it. If you have an older slow cooker you can use less water because the don’t cook as hot as the new ones. If you have a newer model that runs hot or you are not filling it up to the manufacturer’s recommended amount you may need to add a little more liquid.

If you find your’s is too liquidly in the morning you can turn the slow cooker to high and prop the lid open on the handle of a wooden spoon to allow some of the condensation to evaporate. This can take 30 – 60 minutes depending on how much extra there is. Or you can transfer it into a pot on the stove and evaporate the extra liquid that way. It just depends on how soon you need it.

So much depends and varies on your individual slow cooker. Once you’ve made this once you’ll be able to adjust the recipe so it’s perfect for your.
