Marinating chicken after brining is generally not necessary and can sometimes be excessive. Brining itself, especially if it includes herbs and spices, already infuses the chicken with flavors and moisture of salty liquid. Adding a marinade on top of this can overpower the chicken’s natural flavor and the delicate balance achieved through brining.
However, if you’re looking for a specific flavor profile that the brine didn’t provide, a light marinade could be used. In such cases, opt for a brief marinating time and a marinade that isn’t too overpowering or salty, considering the chicken has already absorbed salt from the brine.
Ultimately, the decision to marinate after brining depends on your desired flavor outcome and how pronounced you want the seasoning to be.
