If you don't have a braiser, use a Dutch oven or pot with a lid that can be used in the oven. If you don't have a lid, use aluminum foil to wrap up the top and make it as air tight as possible. If the surface area for Dutch oven or pot isn't large enough, sear the chicken in multiple batches. When cooking it in the oven, you can overlap chicken on top of the other, just know that the chicken at the bottom will not have skin as crispy. It should still be moist and tender.
