In the same way that you preheat an oven, you’ll want to make sure your pot is hot before you start cooking the chicken.
Heat the camp Dutch oven over your coals and melt the butter inside.
Cover your chicken with the (optional) dry rub and place it into the pot (breast side down). Alternatively, you could do this step at home and wrap your chicken so it’s ready to go straight in.
Sear both sides of the chicken. While this is happening, cut your vegetables into fairly thick pieces. (If you don’t want any vegetables then skip this and steps 5-6.)
Once chicken is well browned, remove from the pot and add vegetables into the pot, lining the base with them.
Return the chicken to the pot, setting it on top of the vegetables.
Cover with the lid, and place hot coals on top of the lid so the chicken cooks evenly.
Check the chicken is cooked all the way through and remove from heat.
