If you've ever wondered if you can freeze glass Pyrex and then bake it, the answer is yes! However, there are a few things to keep in mind. First of all, make sure that your Pyrex dish is freezer safe. Most Pyrex dishes will have a symbol on the bottom indicating that they are safe to use in the freezer. If you're not sure, you can always check with the manufacturer. Once you've confirmed that your Pyrex dish is freezer safe, it's important to remember that glass expands when heated. This means that if you put a frozen Pyrex dish directly into the oven, it could crack or shatter. To avoid this, simply place the frozen Pyrex dish on a cookie sheet or other heat-safe surface before putting it in the oven. Additionally, it's important to note that freezing and then reheating food can often cause it to lose some of its flavor and nutrients. So if you're looking to preserve your food as much as possible, freezing may not be the best option.
