Ricotta is an expensive ingredient with a short shelf-life, making it inconvenient and sometimes inaccessible. With a small amount in the freezer, you can work this Italian specialty into cakes and pastas with very little planning.
Yes, ricotta cheese can be frozen, but it is essential to understand how the texture and density will change.
Below we've outline the keys to freezing, storing and thawing ricotta cheese for ultimate flavor/texture preservation.
Enjoy!
Should you Freeze Ricotta Cheese?
Is it Worth It?
While most cheeses last for weeks or months in the refrigerator, ricotta deteriorates very quickly.
Ricotta is a fresh cheese (like cottage cheese, cream cheese and Mozzarella), meaning that its curd forms by the addition of an external acid rather than by a bacteria. The liquids drain away, leaving behind tiny, sand-like grains which, when compacted, are known as ricotta cheese.
So, if you require the fresh texture of ricotta cheese, freezing it steals this unique, smooth texture it can offer in cold applications.
If however, you're baking/heating with it, flavor will remain relatively the same. Read on to see how long ricotta cheese will last in the freezer.
Flavor and Textural Changes
Freezing ricotta for up to two months leaves its flavor untouched. After that, you may begin to notice the flat, disappointing cardboard notes of lipid oxidation.
The texture of ricotta is immediately affected by freezing. Its small proteinaceous curds separate from the liquid whey, emphasizing a grainy mouthfeel and losing some of the smoothness that makes it famous.
Because part of the liquids cluster into ice crystals and must be drained away when they melt, thawed ricotta is often drier and does not confer the same moisture to recipes as its fresh counterpart.
In reality, the differences are hardly noticeable in cooked or heated applications, especially when you pair ricotta with emulsifiers and fatty, high-moisture ingredients like eggs, cream, or different cheeses.
However, avoid using frozen ricotta in recipes where the texture is prominent (such as cheesecake) or where ricotta is the main component (cannoli filling).
How to Properly Freeze Ricotta Cheese
To properly freeze ricotta, you should first remove excess whey. Whey is almost entirely water, and this water will turn into ice, which expands upon freezing, pushing against the delicate protein structure of the cheese.
Do this by using a spoon or a stack of paper towels to press on the cheese.
Stop when no more whey drips out.
Then, stir your ricotta to homogenize the texture just before packing it into airtight containers or bags.
Because ricotta should never be refrozen, it is best to freeze it in small quantities. Dropping spoonfuls of ricotta onto squares of plastic wrap, twisting the square shut to push the air out, and then placing a twist of plastic wrap into a plastic bag works well.
Unopened containers of ricotta can be frozen in their original packaging. In any case, mark the containers with the date so you can throw them out after two months.
How to Thaw Frozen Ricotta
Always defrost frozen ricotta in the fridge. If you're in a hurry, you can place it in a bowl of cold water inside the refrigerator. Because water has a higher heat transfer coefficient than air, it will thaw your ricotta cheese more efficiently.
You should never thaw ricotta at room temperature. As a fresh milk product, ricotta contains numerous spoilage bacteria, and freezing makes it an even more nutrient-dense medium for these organisms; left at room temperature, they will quickly take over.
When the ricotta has fully defrosted, pour off any whey that has separated from the solids, then use a spoon to stir and fluff the remaining curd.
Use ricotta within two days of thawing it. Under no circumstances should you refreeze thawed ricotta! It would be a significant food safety concern as well as a problematic quality issue.
Uses for Frozen Ricotta Cheese
Use defrosted ricotta only in dishes that will apply heat. In this way, the fats will melt, giving the illusion of higher moisture, and the texture changes will be less noticeable.

Other Frequently Asked Questions
Can you freeze ricotta cheese mixtures, including pasta fillings?
Yes, you can; ricotta pasta fillings typically contain several other ingredients, including eggs, which act as emulsifiers and binders to hold the solids and liquids together.
Frozen ricotta fillings may partially separate, as some large ice crystals form and then thaw, but it will not be as noticeable as with plain ricotta cheese. Simply drain away any liquid that separates from the filling, give it a good stir, and then use it like you normally would.
Can you freeze ricotta cheese with egg in it?
Yes. The egg helps ricotta cheese stay together, and it is safe to freeze both the cheese and the egg. Keep it airtight in the freezer, and don’t keep it frozen for more than two months.
How long can you freeze ricotta cheese?
It’s probably best not to freeze it for more than two months. If you really need to freeze it for more than a month or two, it will not become unsafe, but the flavor may start to change. Make sure it is wrapped well and truly airtight--over time, fat oxidation will negatively affect the taste.
Can you freeze ricotta cheese lasagna?
It is certainly safe to do this, but it will be difficult to regain the lasagna’s original texture. Because ricotta cheese separates when frozen, it needs a vigorous stir upon thawing. Stirring would be very difficult to do in between layers of lasagna!
In Conclusion
Smooth, creamy ricotta can improve many recipes, from cookies to pierogies. Follow the guidelines above to keep a little on hand, and it just might make you a more creative cook!

Can you freeze ricotta in original containers, then use it to make pies
Hey Joanna,
The original packaging of most ricotta cheeses aren’t freezer-proof. In other words, the packaging will not be able to withstand the expansion of the cheese as it freezes. To maintain freshness, vacuum sealing would be your best bet. If you don’t have a vacuum sealer, a freezer safe bag will do. Suck out as much air as you can to help reduce the rate of oxidation.
You can freeze the ricotta for pie-baking down the road since the texture change won’t be an issue with baking. Just know that ricotta is highly perishable. Leaving it in the freezer for over 2 months or more, may result in inferior flavor.
Let us know how it goes 🙂

Michael – do you drain the ricotta cheese before vacuum sealing it? Thanks.
Hey there Ginny,
Yes. Draining the ricotta will remove excess water, which turns into damaging ice crystals upon freezing. Preventing excessive ice formation helps keep the texture of ricotta smooth through the freezing process, but it is always best to stir it with a fork or blender after it thaws.
Hope this helps!

Thank you for explaining about ricotta.
Thanks for taking the time to make this post. Excellent information!
