Homemade chicken broth is always the best, but when I am in a pinch and pressed for time, I use boxed chicken or vegetable broth. Both varieties work perfectly in this dish.
When browning chicken, whether it's breast or thighs, here are a few tips:
Always work with room temperature proteins
pat the chicken dry before adding to the pan and don't mess with it! Never move the protein around on the pan; add the chicken or any protein and let it brown undisturbed for at least 5 minutes. This will result in perfect caramelization and a browned glazed protein.
