I developed this, and the great thing about this recipe is that you can coat the breasts, brown them in oil and then refrigerate for up to 8 hours before continuing with the remainder of the recipe, which makes this a great recipe to serve to dinner guests, 30 minutes before serving just drizzle with the marinara sauce and bake! I use recipe#136292 that I make and freeze to use in recipes or recipe#71273 can also be used, your own favorite marinara or pasta sauce can also be used. If you are using more than 7 chicken breasts you will need a larger baking dish and breadcrumb mixture and marinara sauce will need to be increased. It is best to use fresh not frozen thawed breasts for this, with previous experience cooking frozen thawed breasts sometimes tend to create a soggy crust, if you are using frozen thawed make certain that your chicken breasts are completely thawed with no extra moisture left in them. You will love this dish!
