Slow Cooker Two Thirds Fill Rule
The slow cooker two thirds fill rule limits how full the pot gets so heat circulates evenly and swelling ingredients do not boil over.
The slow cooker two thirds fill rule keeps liquid and solids below roughly two thirds of the pot height so food heats through without boiling over or leaving cold pockets at the top. Overfilling is a common reason stews taste watery in the middle and raw at the rim.
Leave headspace for beans and grains that swell. Split oversized batches across two cooks or a larger appliance.
