Can You Put Plastic Ready Meals in the Oven? A Guide to Safe Heating

In today’s fast-paced world, convenience is often a top priority when it comes to meal preparation. Ready meals, also known as microwaveable or frozen meals, have become a staple in many households, offering quick and easy solutions for busy individuals and families.

However, questions often arise about the safety of reheating these plastic-packaged meals in the oven. Can you put plastic ready meal in oven, or is it a recipe for disaster?

Let’s delve into this topic to ensure you can enjoy your convenient meals safely.

What Kind of Plastic Can You Put in the Oven?

Before we address whether you can put plastic ready meals in the oven, it’s crucial to understand the types of plastic and their tolerance to heat. Not all plastics are created equal, and some can withstand higher temperatures than others.

1. Oven-Safe Plastic

Some plastics are specifically designed to be oven-safe. These are typically labeled with symbols indicating they can withstand high temperatures, often up to 400°F (204°C) or more. Common oven-safe plastics include bakeware and microwave-safe containers.

2. Microwave-Safe Plastic

Many ready meal containers are labeled as microwave-safe, but this doesn’t necessarily mean they are suitable for conventional ovens. Microwave-safe plastics are engineered to tolerate the lower temperatures of microwave cooking, typically up to 212°F (100°C).

3. Not Oven-Safe Plastic

Most plastic containers, especially those used for packaging ready meals, are not designed for oven use. These plastics can release harmful chemicals when exposed to high temperatures, posing health risks and potentially damaging your oven.

What Kind of Plastic Can You Put in the Oven

In general, it is not advisable to put plastic ready meals in the oven, especially if they are packaged in containers labeled as microwave-safe.

Microwave-safe plastics are not intended for the dry heat of an oven, and subjecting them to such temperatures can cause them to melt, warp, or release toxic chemicals into your food.

If you want to heat your plastic-packaged ready meal, it’s best to use a microwave, as these containers are specifically designed for that purpose. Always follow the instructions provided on the packaging for safe microwave heating.

Can You Put Plastic Takeaway Meals in the Oven?

The same principles apply to plastic takeaway containers. While these containers are convenient for transporting food, they are not suitable for oven use.

Most takeaway containers are made from microwave-safe plastics, and heating them in the oven can result in deformation, melting, and the potential release of harmful chemicals.

To reheat your takeaway meal, transfer it to an oven-safe dish or use a microwave-safe method.

Can You Put Aluminium Takeaway Containers in the Oven?

Aluminium takeaway containers, often used for dishes like lasagna or baked pasta, are a different story. These containers are generally safe for oven use, but it’s essential to follow some precautions:

  • Check for Oven-Safe Labeling: Some aluminium containers are specifically designed for oven use and may have labels indicating their suitability for baking. These containers are your best bet for safe oven heating.
  • Don’t Use with Acidic Foods: Avoid using aluminium containers with highly acidic foods like tomato sauce, as they can react with the metal and affect the taste of your meal.
  • Cover with Foil: If your aluminium container doesn’t have an oven-safe label, you can still use it in the oven by covering it with aluminium foil. This helps protect the food from direct contact with the container.
  • Avoid High Temperatures: Be cautious not to exceed the recommended oven temperature for the specific container you’re using. Aluminium can melt at very high temperatures.

In most cases, aluminium takeaway containers are a safe and convenient option for reheating food in the oven, but it’s essential to exercise care and follow any manufacturer instructions.

How To Keep Takeout Food Warm?

Sometimes, reheating takeout food in the oven may not be the best option, especially if you’re looking to keep it warm for an extended period. Here are some alternative methods to keep your takeout meals warm:

Use a Food Warmer: Food warmers, often used in restaurants and catering, can keep your takeout meals at a consistent temperature. These devices are designed to maintain food safety and taste without overcooking.

  • Transfer to Oven-Safe Dishware: If you plan to reheat takeout food in the oven later, transfer it to an oven-safe dish before refrigerating it. This way, you can easily pop it in the oven when you’re ready to eat.
  • Thermal Insulated Bags: If you’re transporting takeout, consider using thermal insulated bags or containers designed to keep food warm. These can maintain the temperature of your meal for an extended period.
  • Reheat Using Stovetop or Microwave: When you’re ready to eat, opt for stovetop or microwave reheating for takeout food. These methods are more convenient and safer than using the oven.


In answer to the question “can you put plastic ready meal in oven”, it’s crucial to be cautious when it comes to heating plastic-packaged ready meals or takeaway containers in the oven. Always read and follow the instructions on the packaging and avoid using plastics not designed for oven use.
