Key lime pie, with its tangy sweetness and refreshing flavor, is a beloved dessert that has captured the hearts of many. Originating from the Florida Keys, this pie has become a staple in many restaurants and households across the United States. However, when it comes to storing this delightful treat, many of us are left wondering: does key lime pie need to be refrigerated? In this article, we will delve into the world of key lime pie, exploring its ingredients, preparation methods, and storage requirements to provide you with a comprehensive answer to this question.
Understanding Key Lime Pie
Before we dive into the storage requirements of key lime pie, it’s essential to understand the ingredients and preparation methods that go into making this dessert. Traditional key lime pie is made with a filling consisting of key lime juice, condensed milk, eggs, and sugar, which is then poured into a pre-baked pastry crust. The filling is often flavored with zest and garnished with whipped cream or meringue.
Ingredients and Their Impact on Storage
The ingredients used in key lime pie play a significant role in determining its storage requirements. Eggs, dairy products, and fruit juice are all perishable ingredients that can spoil if not stored properly. The high water content of key lime juice and condensed milk also makes the filling susceptible to bacterial growth and spoilage. Additionally, the pastry crust can become soggy or stale if exposed to moisture or heat.
Acidity and pH Level
Key lime juice is highly acidic, with a pH level of around 2.0. This acidity helps to preserve the filling by creating an environment that is unfavorable for bacterial growth. However, it’s essential to note that acidity alone is not enough to prevent spoilage, and other factors like temperature and storage conditions also play a crucial role.
Storage Requirements for Key Lime Pie
Now that we have a better understanding of the ingredients and their impact on storage, let’s explore the storage requirements for key lime pie. Refrigeration is the most critical factor in storing key lime pie, as it helps to slow down bacterial growth and prevent spoilage.

For short-term storage, key lime pie can be kept at room temperature for up to 2 hours. However, it’s essential to keep it away from direct sunlight, heat sources, and moisture. If you’re not planning to serve the pie within 2 hours, it’s best to store it in the refrigerator to prevent spoilage.
Long-Term Storage
For long-term storage, key lime pie should be refrigerated at a temperature of 40°F (4°C) or below. The pie can be stored in the refrigerator for up to 3 to 5 days, depending on the freshness of the ingredients and the storage conditions. It’s essential to keep the pie covered with plastic wrap or aluminum foil to prevent moisture and other contaminants from entering the filling.
Freezing Key Lime Pie
If you want to store key lime pie for an extended period, freezing is a great option. The pie can be frozen for up to 2 months, and it’s best to freeze it without the whipped cream or meringue topping. To freeze the pie, wrap it tightly in plastic wrap or aluminum foil and place it in a freezer-safe bag. When you’re ready to serve, thaw the pie in the refrigerator overnight and top it with whipped cream or meringue.
Food Safety Considerations

Salmonella and Listeria are two common bacteria that can contaminate dairy products and eggs, and they can grow rapidly in perishable foods like key lime pie. To prevent foodborne illness, it’s essential to handle and store the pie safely.
Safe Handling Practices
To ensure safe handling practices, always wash your hands before and after handling the pie, and make sure to clean and sanitize any utensils and equipment that come into contact with the filling. It’s also essential to store the pie at a safe temperature and to consume it within the recommended timeframe.
