Summarize:

Marinades add flavor and keep your chicken juicy. You can experiment with a range of store-bought marinades, or make your own at home. Put the marinade in a heavy-duty zip-lock bag, then fully submerge the breasts in the marinade. Seal the bag tightly and put it in the fridge. After 6 to 8 hours, drain the marinade and proceed with your recipe. Examples of store-bought marinade flavors you can try are Lemon Pepper, Orange Sesame, and Teriyaki.
Soak your chicken in a marinade for 6 to 8 hours for a richer flavor.
