Key lime pie, with its tangy flavor and smooth texture, is a beloved dessert around the world. Made from key lime juice, condensed milk, and eggs, it’s a classic recipe that has been passed down through generations. However, like any perishable food item, key lime pie has a limited shelf life. If you’ve baked a key lime pie and are wondering whether it’s still good after a week, you’re not alone. In this article, we’ll delve into the world of key lime pie, exploring its ingredients, preparation methods, and most importantly, its shelf life and safety.
Introduction to Key Lime Pie
Key lime pie is a dessert that originated in the Florida Keys, where key limes are abundant. The traditional recipe consists of a filling made from key lime juice, condensed milk, and eggs, baked in a pie crust. The acidity of the key lime juice reacts with the sweetness of the condensed milk, creating a unique and refreshing flavor profile. Key lime pie is often served chilled, garnished with whipped cream or meringue.
Ingredients and Preparation
The ingredients used in key lime pie are relatively simple, but the preparation method can affect the pie’s shelf life. A traditional key lime pie recipe includes:
- 3 large egg yolks
- 1/2 cup key lime juice
- 1/2 cup condensed milk
- 1 teaspoon grated lime zest
- 1 pie crust (homemade or store-bought)
The preparation method involves whisking together the egg yolks and key lime juice, then adding the condensed milk and lime zest. The mixture is poured into a pre-baked pie crust and baked until the filling is set. The pie is then chilled before serving.
Shelf Life and Safety
The shelf life of key lime pie depends on several factors, including the storage method, handling, and ingredients used. Proper storage is crucial to extending the shelf life of key lime pie. The pie should be stored in the refrigerator at a temperature of 40°F (4°C) or below. If stored properly, key lime pie can last for several days. However, its quality and safety may degrade over time.
Bacterial Growth and Food Safety
Key lime pie is a potentially hazardous food due to the presence of eggs, dairy, and moisture. Bacteria like Salmonella and Staphylococcus aureus can grow rapidly in these conditions, especially if the pie is not stored at a safe temperature. It’s essential to check the pie for any signs of spoilage, such as an off smell, slimy texture, or mold growth. If you notice any of these signs, it’s best to err on the side of caution and discard the pie.
Is Key Lime Pie Good After a Week?
While key lime pie can be safely stored in the refrigerator for several days, its quality and safety may degrade over time.

If you’ve stored the pie in the refrigerator at a consistent temperature below 40°F (4°C) and it looks, smells, and tastes fine, it might still be safe to eat. However, it’s crucial to use your best judgment and consider the following factors:
- The pie’s appearance: Check for any signs of mold, slime, or discoloration.
- The pie’s smell: A sour or off smell can indicate spoilage.
- The pie’s taste: If the pie tastes sour, bitter, or unpleasantly different from when it was freshly baked, it’s best to discard it.
Freezing Key Lime Pie
If you want to extend the shelf life of your key lime pie, consider freezing it. Freezing can help preserve the pie’s quality and safety for several months. To freeze key lime 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 serve chilled.
Thawing and Serving
When thawing a frozen key lime pie, it’s essential to do so safely to prevent bacterial growth. Always thaw the pie in the refrigerator, never at room temperature. Once thawed, serve the pie chilled, garnished with whipped cream or meringue, if desired.
