Yes you can make bread with your grill. Flat breads are a breeze and even raised breads work great. All you need to bake bread is an enclosed space that is heated. For this a grill works perfect. One thing to remember though is that grills can get much hotter than your oven and temperature control is not as precise. Delicate breads that can be a challenge in the oven should be avoided on the grill until you really get the hang of it.
Temperatures: My experience suggests that breads cook faster (sometimes twice as fast) on the grill as they would in the oven. Like I said grills can produce a lot more heat than you traditionally use to bake breads so try to keep a relatively low temperature. Use an oven thermometer placed near the bread to monitor temperatures. Also, because of the natural air flow inside your grill (whether charcoal or gas) you get more convection than you do in your oven. This is why it is important to keep a close eye on breads when you are grilling.
Flat Breads: You can grill tortillas and pizza crusts quickly and easily by using frozen bread dough. Try using the roll dough because it's already divided into nice pieces. Roll out into thin circles and place on a preheated grill. Watch to make sure they don't burn and remove from the grill when they are a nice golden brown. For tortillas remove while they are still pliable. For pizzas let them get a little stiff, top with pizza sauce, cheese, etc. and put back on the grill until the cheese is melted. I recommend doing only a few at a time (maybe one until you get the hang of it) so you don't burn the bottoms.
A few extra tips:
- Pizza stones are great, but before you put any cookware on your grill make sure it is safe to use. Some things do not stand up well to the heat and flame of a grill.
- Although not necessary indirect grilling can help create a more even baking environment for breads. Direct heat can cause the bottom of breads to get burned quickly.
- Flat breads need to be able to hold together on your grill. You can place them right on the grate but if the grate doesn't provide enough support you have trouble. Make breads thicker if you have a wide slotted grate.
- A bakers peel can be very helpful getting bread on and off the grill. These are those wide board tools you see in bakeries. Super Peel is a great tool, well worth the money, that has a conveyor belt that really makes it easy to get bread onto the grill easily, especially pizzas.
- These days many grill makers are touting the versatility of their products. Check with your manufacturers website to see if they have specific accessories to help you bake on your grill.
