What can you use instead of cardboard to cook in the oven?

We have concluded that cooking your pizza directly on the cardboard base it came with is not a good idea. However, there are still some options.

  1. An alternative option usually recommended on pizza packaging is to cook your pizza directly on an oven shelf. You can heat your pizza from the underside more efficiently by using an oven rack. This will result in a crispy crust. Cooking directly on an oven rack has one major disadvantage: grease, and possibly even toppings, can end up in your oven.
  1. On a Pizza Stone: A pizza stone is an excellent surface for baking pizzas, as the name suggests. Most pizza stones are made from stone or ceramic and have a great heating surface that produces crispy crusts. The porous baking stone’s porous surface helps to remove some moisture from the pizza dough. This creates a crispy crust.
  1. On a Pizza Pan: A pizza frying pan is another reliable way to cook a pizza. There are many types of pizza pans. Each one has its advantages and disadvantages. Most pizza pans, though not all, are round and suitable for typical store-bought pizzas. A pizza pan with a perforated base plate will make your crust crispier. It’ll also get more heat from the bottom of your oven. A perforated bottom allows your pizza to bake faster, but it does allow some grease to drip through, as when cooking directly on an oven rack. If you need food processors, things to check before buying a food processor for your home kitchen.

However, keep in mind that a cookie sheet won’t make a crust as crisp as a pizza stone or pan.
  1. When cooking with aluminum foil. For most people, foil is a more straightforward and more accessible option than the other methods.

Aluminum foil has one of the most significant benefits. You don’t even have to clean it. Once you’re done, fold it up and toss it in the trash bin.

However, aluminum foil has a downside. It doesn’t provide much support when you slice the pizza.
