Meringue Shelf Life Explained

How long are meringues good for? Meringues are a delightful, airy treat, but how long do they stay fresh? To ensure that you enjoy them to their full potential, our food chemists conducted tests to determine their shelf life. Meringues Made Newly: When stored in an airtight container at room temperature, homemade meringues last about 1 to 2 weeks. Humidity is their biggest enemy, as moisture can make them soft and chewy. Store-Bought Meringues: Meringues that are packaged commercially typically contain preservatives, which extend their shelf life from two to four weeks when left unopened. For the best texture, consume them within a week of opening. Freezing and refrigerating: While refrigeration isn’t recommended (it introduces moisture), you can freeze meringues for up to 2 months. To avoid sticking, place parchment paper between the layers of a freezer-safe container. Before using, thaw at room temperature. Signs of Spoilage: Meringues should be thrown away if they become sticky, discolored, or smell bad. To keep them crisp, they need to be stored in the right way. For long-lasting meringues, keep them dry and airtight. Follow these tips, and your meringues will stay deliciously crisp! Want to learn more about food shelf life? Take a look at our expert guides!
