Yes! If you're looking for a crispy crust and don't want to heat up your kitchen, cooking the pizza on the grill is a great option. Just be sure to preheat the grill to 400 degrees Fahrenheit before adding the pizza. Place the cast iron skillet on the grill and cook for about 12 to 15 minutes, or until the crust is golden brown and the cheese is melted. If you're cooking the pizza on the grill, be sure to close the lid so that the heat can evenly cook the crust, and check halfway through the cooking time.
