When we say this french onion chicken skillet is one of the best chicken dinners weve ever made, we are not exaggerating. Not even a little bit. For all you french onion soup lovers out there, get ready to have your minds blown; we turned one of our all-time favorite soups into a skillet dinner, adding chicken into the mix for some more protein and to make it a more well-rounded meal. But other than that, we prepared the onions almost exactly the same way we would to make the soup.
