Cooking a frozen pizza in a Kalorik pizza oven is easy and straightforward. First, preheat the oven to 375 degrees Fahrenheit. Once it has reached the desired temperature, place the frozen pizza on the baking tray and insert it into the oven. Cook for 15-20 minutes or until the cheese is melted and lightly browned. Make sure to check on your pizza regularly to ensure that it does not burn. When finished cooking, remove from the oven carefully using an oven mitt or kitchen towel and let cool for a few minutes before serving. Enjoy!
