Yes, you can bake a loaf of bread on your barbecue. In fact, a barbecue can be an ideal place to bake your bread. The heat is dry and intense which does a wonderful job on most breads.
A few things to keep in mind before you try:
1.) Use indirect heat – most breads will suffer from high-heat directly underneath the loaf,
2.) when you open the lid of a typical barbecue, there is a lot of heat loss – so resist the temptation to constantly check your bread as it’s baking,
3.) the inside of your house will not smell like fresh baked bread – get over it,
