Leftovers can be stored in a covered container in the refrigerator for up to 2 days. They can also be frozen in a freezer-safe container for up to 2 months. To reheat, allow the dish to come to room temperature, then microwave it until hot.
You can substitute chicken thighs for chicken breasts if preferred.
Be sure to season both the chicken and potatoes with salt and pepper. For extra flavor, consider adding garlic powder and/or paprika to the seasoning mix.
