A plastic casserole is a kitchen container or dish made from plastic material, typically designed for serving and storing hot or cold dishes. These casseroles come in various shapes and sizes, including rectangular, oval, and round, and are equipped with tight-fitting lids to keep the food warm and fresh. They are a popular choice for picnics, potlucks, and outdoor gatherings due to their lightweight and durable nature, making them easy to transport. Plastic casseroles are also known for their insulating properties, helping to retain the temperature of the food. They are available in a range of colors and designs to suit different tastes and kitchen decor styles. While plastic casseroles are not suitable for cooking in the oven, they are ideal for serving and keeping dishes at the desired temperature during meals and social events.
