To know when sausage is cooked in a crock pot, you can check it by: - Using a meat thermometer: Insert a meat thermometer into the thickest part of the sausage. The internal temperature should be 165 degrees Fahrenheit. - Tasting it: Sausage is cooked when it is no longer pink and has a firm texture. You can also taste a small piece to ensure it is cooked. - Cutting into it: If you cut into the sausage and it is no longer pink, and the juices run clear, it is cooked through.
