Can You Put Styrofoam in the oven. Styrofoam, also known as polystyrene, is a lightweight, yet durable material that is widely used for packaging and insulation.

However, the question of whether it can be put in the oven is a common one that raises concerns about safety and environmental hazards.

While some people believe that it is safe to use in the oven, others are skeptical about its ability to withstand high temperatures without releasing harmful chemicals into the air.

In this article, we will examine the pros and cons of using Styrofoam in the oven and explore some of the alternative materials that can be used instead.

The short answer is no, it is not safe to put Styrofoam in the microwave. The microwave can cause the plastic to break down and release harmful chemicals into your food.

In addition, the plastic can also melt, creating a fire hazard. If you need to reheat food in the microwave, use a microwave-safe dish made of glass, ceramic, or plastic.

Why is Styrofoam harmful in the oven?

When Styrofoam is exposed to high temperatures, it can break down and release toxic fumes. These fumes can contain harmful chemicals such as benzene, toluene, and styrene. These chemicals can cause serious health problems if they are inhaled or ingested.

In addition, when Styrofoam is exposed to high temperatures, it can catch fire. This is because the plastic material is highly flammable and can release toxic smoke when burned. This smoke can contain harmful chemicals and gases that can be harmful to your health.

What are the alternatives to using Styrofoam in the oven?

If you need to use a material that can withstand high temperatures in the oven, there are several safe and eco-friendly alternatives available, such as:

  1. Glass or Ceramic Dishes: Glass and ceramic dishes are great alternatives to Styrofoam as they are oven safe, durable, and easy to clean.
  2. Aluminum Foil: You can use aluminum foil to wrap food before baking it in the oven.
  3. Silicone Baking Mats: Silicone baking mats are heat-resistant and can be used as a liner for baking sheets or oven trays.
  4. Baking Paper: Parchment paper or baking paper can be used to line baking trays or pans to prevent food from sticking.
  5. Cast Iron: Cast iron cookware is an excellent alternative for baking as it is oven safe, long-lasting, and distributes heat evenly.
  6. Stainless Steel: Stainless steel cookware is also oven safe and can be used for baking or roasting.
  7. Baking Stones: Baking stones are made of porous material that can absorb moisture and distribute heat evenly, making them ideal for baking pizzas and other baked goods.
  8. Baking Pans: Baking pans made of metal, glass, or ceramic are a great alternative to Styrofoam for baking and roasting.


Why shouldn’t I put styrofoam in the oven?

Styrofoam contains chemicals such as styrene and benzene, which release toxic fumes when heated. These fumes can be dangerous to inhale and can also contaminate food cooked in the oven.

Can I put styrofoam in the oven if I put it in a covered dish?

No, it is still not recommended to put styrofoam in the oven even if it is covered. The heat can still cause the styrofoam to release toxic fumes, which can seep into the covered dish and potentially contaminate your food.

What should you do if you accidentally put styrofoam in the oven?

If you accidentally put styrofoam in the oven, you should immediately remove it and open the windows to let out the toxic fumes. Avoid breathing in the fumes and seek medical attention if you experience any respiratory issues.


In conclusion, putting styrofoam in the oven is not recommended as it is a hazardous material that releases toxic fumes when exposed to high heat. The fumes released from styrofoam can cause harm to human health and the environment. Furthermore, styrofoam is not heat-resistant and will melt, deform, or even catch fire in the oven. To prevent these hazardous outcomes, it is best to avoid using styrofoam in the oven. Instead, use oven-safe materials like glass or metal for cooking or baking.
