To cook boneless, skinless chicken breasts in a crock pot, it typically takes about 2.5 to 3.5 hours on the low setting to reach the safe internal temperature of 165°F (74°C). Cooking times may vary depending on the slow cooker model, size of the chicken breasts, and recipe specifics. For larger recipes or bone-in chicken breasts, cooking on low can take 4-6 hours. Cooking on high heat generally requires less time, around 2-4 hours, but checking with a meat thermometer is recommended to avoid overcooking or undercooking. Summary of cooking times:
- Boneless, skinless chicken breasts on low: 2.5 to 3.5 hours
- Larger portions or bone-in breasts on low: 4 to 6 hours
- On high: 2 to 4 hours (monitor temperature)
Always ensure the chicken reaches at least 165°F internally for safety and best texture.
