Key lime pie is one of those desserts that just seems to get better with age. I’ve had key lime pies that were a week old and they were still delicious. So, how long does key lime pie last in the fridge?
The answer is: it depends. Key lime pie will last anywhere from 3-5 days in the fridge, depending on how well it’s sealed. If you have a slice of key lime pie that’s not quite finished, you can wrap it tightly in plastic wrap or aluminum foil and it will last for an extra day or two.
Key lime pie is a delicious dessert that can be enjoyed all year round. But how long does this tasty treat last in the fridge?
Unfortunately, key lime pie does not keep well in the fridge.
After just a few days, the crust will become soggy and the filling will start to separate. So if you want to enjoy your key lime pie at its best, eat it within a day or two of making it.
Of course, you can extend its life by freezing it.
Key lime pie freezes beautifully and will last for several months in the freezer. Just wrap it tightly in plastic wrap before popping it into the freezer. When you’re ready to enjoy it, thaw overnight in the fridge before serving.

How Can You Tell If Key Lime Pie Has Gone Bad?
When it comes to key lime pie, there are a few telltale signs that it has gone bad. The most obvious is if the filling has started to turn brown or black. This is a sign of spoilage and means that the pie should be thrown out.
Another sign that key lime pie has gone bad is if the filling is starting to separate from the crust. This is another surefire sign of spoilage and means you should toss the pie. Finally, if the key lime pie just doesn’t taste right, it’s probably best to throw it out.
While these are all general guidelines, keep in mind that ultimately your best bet is to use your own judgement when it comes to determining whether or not key lime pie has gone bad.
Is Key Lime Pie Good After a Week?
Key lime pie is one of those desserts that is just as good, if not better, after a week. The key lime filling has a chance to set up and the flavors meld together beautifully. I would recommend storing it in the fridge, however, to keep it fresh tasting.
How Long is Pie Good in the Fridge?
Different types of pie have different expiration dates. For example, fruit pies made with fresh fruits can last for about 2 days in the fridge, whereas cream pies or custard pies should only be kept for 1 day. If your pie has been sitting out at room temperature for more than 2 hours, it’s best to throw it away.
Does Store Bought Key Lime Pie Need to Be Refrigerated?
Most store-bought key lime pies come pre-refrigerated, so you don’t need to worry about keeping it cold yourself. However, if you do purchase a key lime pie that isn’t already refrigerated, you should put it in the fridge as soon as possible. Key lime pie is made with milk and eggs, which can spoil quickly at room temperature.
So to be safe, always err on the side of refrigeration!

How Long Does Store Bought Key Lime Pie Last
When it comes to store-bought key lime pie, how long it lasts depends on a few different factors. For example, if the pie is made with fresh key limes, it will only last for 2-3 days in the fridge. However, if the pie is made with bottled key lime juice, it can last up to a week in the fridge.
Additionally, if you freeze store-bought key lime pie, it will keep for 2-3 months. So, ultimately, it just depends on how the pie was made and what you plan to do with it. If you want to extend its shelf life, freezing is your best bet!
How Long Can Key Lime Pie Be Left Out
Most people don’t realize that key lime pie can actually be left out for a significant amount of time without spoiling. In fact, it can safely be left out for up to four hours without any risk of food poisoning. After four hours, the risk of food poisoning increases, but the key lime pie will still be safe to eat for up to eight hours.
After eight hours, the key lime pie should be thrown away.
So, if you’re ever in a situation where you need to leave your key lime pie out for a few hours, don’t worry! It will still be delicious when you come back to it.
Can Key Lime Pie Make You Sick
Key lime pie is a delicious dessert that can be enjoyed by people of all ages. However, there is a small risk that it could make you sick. The key limes used to make the pie are typically very acidic, which can cause stomach upset if consumed in large quantities.
Additionally, the egg whites in the pie filling can sometimes harbor bacteria, which can lead to food poisoning if not cooked properly.
To avoid getting sick from key lime pie, it is important to purchase pies from reputable bakeries or restaurants. Make sure that the key limes are fresh and that the egg whites are cooked until firm.
If you are making your own key lime pie at home, be sure to use pasteurized eggs to reduce the risk of food poisoning. Most importantly, enjoy your key lime pie in moderation!
How Long Does Key Lime Pie Last in the Freezer
Assuming you mean an unopened, store-bought key lime pie:
Most key lime pies come with a “best by” date on the packaging. This is the date that the manufacturer considers the pie to be at its best quality.
However, this does not mean that the pie will go bad immediately after this date. In fact, a key lime pie can last for several weeks after its “best by” date, as long as it is stored properly.
If you have an unopened key lime pie that is past its “best by” date, you can still enjoy it if it has been stored in the fridge or freezer.
For optimal quality, eat the pie within 3-4 weeks of its “best by” date. If you freeze the pie, be sure to thaw it in the fridge overnight before eating.
