Recipe Notes
Chicken Broth: Feel free to replace the chicken broth with pineapple juice, apple juice, vegetable broth, or other liquids depending on the flavor you're looking for.
Seasoning: You can season the chicken with anything you like. All-purpose seasoning, poultry seasoning, BBQ dry rub, Tony Chachere's, salt & pepper, and any dry spice blend will work just fine.
Internal Temperature: 165° Fahrenheit is the food-safe internal temperature recommendation for chicken. To prevent dry, tough, or chewy chicken breasts, we recommend you stop cooking when then internal temperature reaches 160°F and set the chicken aside to rest. The residual cooking during the rest time will bring the chicken to 165°F while keeping the chicken moist and juicy.
