Typically, you bake frozen pizza in the oven or the microwave, but doing so often fails to get that crispy crust that some people prefer. On a warm day, instead of heating up your oven, take the pizza outside to cook on your grill, guaranteeing a very crispy pizza crust. To keep the crust from burning, you'll need to prepare your grill for indirect grilling.
Heat your grill to 400 degrees Fahrenheit and prepare for indirect heat. For a gas grill, turn only the burners on one side of the grill. If you are using a charcoal grill, place a drip pan in the center of the grill and the coals on either side of the pan.
Unwrap your frozen pizza and place it on the heated grill. Make sure the pizza is directly over the drip pan if you are using a charcoal grill or on the unheated side of a gas grill.
Cover the grill and let the pizza cook for 10 to 13 minutes for a standard-size, traditional pizza. Rotate the pizza a half turn, then close the lid and continue to cook for another 10 minutes, or until the crust is golden brown and crispy, to your liking. Use a food thermometer to ensure that the pizza has reached an internal temperature of at least 160 F.
