Common mistakes
Avoid over-crowding the slow cooker, as this can lead to uneven cooking and excess moisture that dilutes the sauce.
Do not remove the lid frequently during the cooking process, as each lift releases significant heat and extends the overall time needed to reach the safe internal temperature for the poultry.
How to tell it’s done
The chicken is considered fully cooked when it reaches an internal temperature of 165°F (74°C). At this stage, the meat should be opaque and firm to the touch, yet easily pulled apart with a fork.
The sauce will have thickened slightly from the rendered juices, coating the vegetables and chicken in a glossy, flavorful layer.
