You may like to consume a wonderful pizza, so you place it in the oven and walk away. You discovered a few minutes later that you neglected to remove the cardboard off the bottom, but can you microwave your pizza with the cardboard? Can you bake with cardboard?

To be on the safe side, do not put cardboard in the oven. Cardboard has an extremely high ignition point of 427 degrees, thus it won’t ignite if it remains below this temperature.

Yet, depending on the sort of oven you use, there is still a potential it may catch fire.

Why You Should Not Put Cardboard in The Oven

1. Threats of spontaneous combustion

Unfortunately, cardboard may catch fire if heated to 427 degrees. Most pizzas bake at 425 degrees, and the two-degree difference is much too close for comfort. The kind of oven you use may greatly enhance or lessen the likelihood of your cardboard catching fire.

The hazards are larger when using an older oven than when using a modern model because the heating components in older ovens are more exposed to the interior of the oven.

2. Slows down cooking time

Putting your cardboard on the bottom of your pizza or whatever item you’re microwaving may increase cooking time while also preventing the bottom of your pizza from becoming nice and crispy.

3. It makes your food taste weird

Even if your cardboard does not completely catch fire, it might begin to emit smoke and smells. These vapors may leave an unpleasant flavor in your meal and make your oven and kitchen smell.

What to Use Instead of Cardboard

We have a few items you may use instead of cardboard in the bottom of any meal you want to microwave to keep you safe and not affect the flavor of your food.

Cookie sheets

A cookie sheet is the ideal substitute for the cardboard you put beneath your pizza. The bottom will finally heat up to cook and crisp the bottom of the pizza.

Not only is it great for pizza, but it’s also great for frozen foods like casseroles and chicken nuggets. There is no danger of fire, and the food is deliciously crispy. It’s a win-win scenario for everyone.

Casserole Dish

If you don’t have a flat cookie sheet, a casserole dish or baking pan is your best bet. This is not large enough to hold your pizza, but it is suitable for baking other sorts of frozen meals.

Aluminum Foil

If you just have aluminum foil and nothing else to put your pizza on, wrap the rack in it. Please remove the racks and cover them in aluminum foil before preheating the oven.

This is an excellent and less expensive alternative to cookie sheets and casserole plates for baking without allowing anything to leak into the oven.

Pizza Block

You may bake your pizza on three specially manufactured ceramic sheets straight in the oven. They keep the cheese from oozing into the oven while also making the pizza dough crispy.

Directly on The Rack

Certain dishes may be baked directly on the oven rack. If your meal arrives in an oven-safe container, place it immediately on the rack.
