How Long Can Unopened Cream Cheese Sit Out? [Make It Last Longer]

In my experience, cream cheese is a delicious ingredient I often find myself using in most of my recipes.

But – can we leave it sitting out even if it’s unopened? And if so, what precautions should we watch out for?

For optimal safety, cream cheese should not be left out at room temperature for more than two hours, as recommended by the USDA’s food safety guidelines. Dairy products like cream cheese can rapidly become unsafe due to bacterial growth, such as Salmonella and Listeria, when kept out of refrigeration for extended periods. If cream cheese remains unrefrigerated for over two hours, especially in temperatures above 40°F, it’s advised to discard it to prevent foodborne illnesses. To preserve cream cheese’s quality and safety, always store it in the refrigerator at or below 40°F and tightly seal it after each use. If you’re uncertain about the time cream cheese has been left out, it is safer to err on the side of caution and dispose of it.

Below, I will discuss the risk of cream cheese sitting out, how long it will last, and ways to store it properly. 

Leaving Cream Cheese Out At Room Temperature

As a parent, I’m sure you know that cream cheese is a popular ingredient to cook dips or bake desserts!

I got sidelined by my kids and wound up leaving the cream cheese out for a few hours.

By the time I had found it, it was no longer cold – sadly I had to toss it in the trash.

Cream cheese has ingredients consisting of fresh and fat-full milk. As we all know, milk expires rather quickly and only lasts a few days once you open it.

Cream cheese has expiration dates on it, just like milk does, to prevent consumers from eating spoiled products.

Opened vs. Unopened Cream Cheese – At Room Temperature 

You may be wondering – is there a difference between unopened and opened cream cheese?

Surprisingly enough, cream cheese that has been opened can still last up to two weeks, so long as it remains refrigerated.

In contrast, unopened cream cheese can last one month past the expiration date if kept in the refrigerator! 


A good tip is if you have multiple packages of cream cheese and one of them is open, always consume the open one first as long as it isn’t spoiled. 
It’s essential to keep in mind that cream cheese can get spoiled quickly, meaning it must stay in the fridge if you aren’t going to be using it within a few hours’ time. 

If it’s your first time using cream cheese, it’s important to learn how long it can sit out, steps to take to prolong its lifespan and more.

Unopened cream cheese can last up to one month past its expiration date and still be safely consumed if it has been properly refrigerated. 

If you don’t plan to use your cream cheese within the expiration window, you can always choose to freeze your cream cheese.

Due to the fat in the dairy, cream cheese does well in the freezer and can be kept for two months in its original, unopened packaging with no ill effect. 

Cream cheese shouldn’t be left at room temperature for longer than two hours. Since it contains fresh dairy, it can quickly spoil. 

This rule goes for unopened or opened packages of cream cheese. It doesn’t change the time frame it can be left out.

Because of this time frame, it’s important to keep in mind after grocery shopping and not leaving it in your car for an extended time. 

Food Risk Of Cream Cheese After Being Left Out

A huge concern when it comes to the food safety of cream cheese is the presence of E.Coli contamination and bacterial growth.

It can grow in a very short amount of time without you even realizing it – and it doesn’t have a smell or taste.

Food poisoning is dangerous and can make you very ill, and it is definitely a risk of cream cheese if you leave it out too long and it’s spoiled. 

Is It Safe To Eat Cream Cheese Left Out Overnight?

Even though life gets busy and we can be forgetful sometimes, it’s never safe to consume cream cheese left out overnight. says you should throw out cream cheese that has been left at temperatures above 40 degrees for over four hours.

Once this happens, bacteria start to grow quickly after just two hours of room temperature exposure. 

It might have crossed your mind before to let the cream cheese sit out overnight to soften, but this is something you should avoid.

Bacteria like E. Coli can grow on soft cheeses after just two hours of sitting at room temperature. 

How To Soften Cream Cheese Without Exposing It To Bacteria

There are many easy options for softening cream cheese. Luckily, it softens quickly. One of the best options is letting it sit at room temperature for about 20 minutes.

This should be the perfect amount of time for it to soften enough to use for your recipe.

(Remember to set a timer if you are working on other things, so you don’t forget to return to it.)

I know we’ve all been there, where you decide to make a dessert on a whim, and it calls for softened cream cheese or softened butter, and you’re in a hurry.

Another option to softening your cream cheese quickly is by using the microwave- as I’m sure this has crossed your mind before.

This can be sort of tricky at first because if you get distracted, you may end up with a bowl full of melted cream cheese instead of a softened block. 

All you have to do to soften in the microwave is unwrap the block of cream cheese and place it on a microwave-safe plate.

I usually start with 5-10 seconds and check it. Then I’ll turn it ¼ of the way and repeat on all four sides.

Typically after 20-25 seconds, my cream cheese comes out perfect and with just the right amount of softness. 

When softening cream cheese you want to ensure you do it properly without exposing it to bacteria.

When microwaving it, make sure it hasn’t been left out longer than two hours. If it has been in the refrigerator be sure to check the expiration date as well.

Always be sure that it has previously been stored in an air-tight containers, this allows bacteria to not be able to easily enter.
