Start by preparing your chicken. For whole chicken breasts, you can either leave them as is or slice them into thinner pieces for more efficient marinating and cooking. Be sure to trim any excess fat.
Choose the marinade you'd like to use. Once decided, gather all of the ingredients for the chosen marinade and add them to a zip-top bag or a shallow dish. Mix the ingredients well until everything is fully combined.
Place your prepared chicken into the bag or dish with the marinade. If using a zip-top bag, seal it securely, then gently move the chicken around inside the bag to ensure it's fully coated with the marinade. If using a shallow dish, make sure all pieces are well coated with the marinade, then cover the dish with a lid or plastic wrap.
With the chicken fully coated in the marinade, transfer it to the refrigerator. Allow the chicken to marinate for at least 30 minutes, but if time allows, leave it for a few hours or even overnight for an even richer flavor (but don't go over 24 hours).
Once the marinating process is done, take the chicken out of the fridge and let it come to room temperature before you start cooking. Use your preferred cooking method (grilling, baking, pan-searing, or slow cooking) to cook the marinated chicken.
