Chicken – How to prevent burned chicken breasts when cooking on the stovetop

It really depends on the texture you are looking for in your finished product. If you want a chunky chicken salad then bake your chicken breasts seasoned or not, I season mine, and then cube them. If you want something a little more exciting pan grill the breasts to the point of a little char and then dice. If you want your chicken to be flavorless and get all of your flavor from the mix you are tossing your chicken into, boil it or put it in a slow cooker if you are cooking up a big batch.

It all really comes down to how you like to eat your chicken salad, and more importantly how pretty you want it to look in your serving method, because a cajun blackened chicken salad sandwich can look down right homely. I say try them all until you fall in love with one temporarily and when that has lost its passion try a different version.

Also as a side note if I am preparing it for me and not for someone else, so it doesn't have to be all white and pretty, I use thighs instead of breasts since they are more forgiving and generally cheaper. If I am not just breaking down a whole chicken and using the leftovers.

The only method I have personally found to be reliable for grilling/pan-frying chicken breasts to a relatively uniform doneness is to pound them very, very thin with a mallet or rolling pin. Thin, as in scaloppine-thin, so that it cooks almost instantly in the pan.

Every other stovetop-only method is almost certainly going to produce a bland, tough cut, regardless of whether you press it down or not. As noted in my comment, my usual (lazier) method that does not involve pounding is to get a nice sear in the pan, then jam in a temperature probe and bake it in the oven until it's done (the USDA recommends 165° F, I usually don't go quite that high).

If pressing the meat actually accomplishes anything at all, it would most likely be to just squeeze out whatever tiny amount of precious juices the breast does have, and possibly give you slightly more even cooking on the exterior only; it will not help to cook the interior much faster unless, as stated above, the cut has been pounded extremely thin and flat, at which point it doesn't really matter.

P.S. Salt and olive oil is a terrible "marinade" for any cut of meat, especially a chicken breast. The salt is just going to get suspended in the oil and never reach the meat at all, and the oil itself won't have much of an effect on such a lean cut. You really need to change your marinade as well, preferably to something water-based (or at least not 100% oil).
