One of the foremost advantages of small glass casserole dishes is their durability. Made from tempered glass, they can withstand high temperatures without cracking or breaking, making them perfect for oven use. Unlike plastic containers, glass does not leach harmful chemicals into food, ensuring that your meals remain safe and healthy. Moreover, glass is non-porous, which means it won't absorb odors or stains from foods, allowing for easy cleaning and maintenance over time.
