What You'll Learn
How long does ricotta cheese last in the fridge?
Fresh ricotta cheese is a soft cheese with a high moisture content, which means it doesn't last as long as harder cheeses like Parmesan or aged Cheddar. An unopened container of ricotta will typically stay fresh for about two weeks in the fridge, but some sources suggest it may last between two to four weeks. The "'use-by' date on the package can be used as a guideline, but it's not an exact science and ricotta may be good for one or two weeks after this date.
Once opened, ricotta cheese is exposed to air, which causes it to spoil faster. In general, opened ricotta will last for about one week in the fridge, provided it is stored at a temperature between 35 and 40 degrees Fahrenheit (normal fridge temperatures). Some sources suggest ricotta may last for up to two weeks after opening, but it's important to inspect the cheese for signs of spoilage after one week.
Spoiled ricotta cheese may develop mold, which can be green, blue, or soft pink in colour. The cheese may also turn yellowish instead of its usual creamy white colour. Another sign of spoilage is a sour or fermented smell, even if the odour is not particularly unpleasant. If ricotta cheese smells sour, it should be discarded.
To extend the shelf life of ricotta cheese, it can be frozen, although this may affect the texture and taste of the cheese.

What are the signs of spoilage?
Like all dairy products, ricotta cheese has a finite shelf life and can go bad. Recognizing the signs of spoilage is essential for safety and enjoyment. Fresh ricotta cheese should have a smooth, creamy, and velvety texture with a mild, pleasant aroma. Here are the signs that indicate that ricotta cheese has gone bad:
Discolouration
Any discolouration or change in appearance is a sign of spoilage. If the ricotta has turned yellowish or brown, it has likely gone bad.
Mould
Although some types of soft cheeses may be coated with an edible layer of mould, any mould that grows on ricotta is a sign of spoilage. The mould spores have likely infiltrated the entire container, and it should be discarded.
Excess liquid
If there is a layer of water sitting atop the cheese or if the ricotta becomes excessively watery, it is a sign of spoilage.
Texture issues
If the ricotta becomes grainy, crumbly, rubbery, or lumpy, it has likely gone bad. Fresh ricotta should neither exhibit a sour smell nor a grainy texture.
Off smell
Ricotta cheese has a very mild odour and almost no odour when fresh. If it begins to smell sour, fermented, or rancid, it is a sign of spoilage.
It is important to note that consuming spoiled ricotta cheese can be unpleasant and pose a health risk, potentially causing symptoms such as nausea, vomiting, and diarrhoea. Proper storage is crucial to prevent spoilage and maintain quality. Ricotta cheese should be stored in the refrigerator, ideally between 1.6°C and 4.4°C (35°F and 40°F). An unopened container can last for about one to two weeks past the "use-by" date, while an opened container should be consumed within three to five days. Freezing ricotta can extend its shelf life but may alter its texture.

How to store ricotta cheese?
Ricotta cheese is a soft spreadable cheese with a high moisture content, which creates a breeding ground for bacteria. This means that ricotta cheese doesn't last as long as harder cheeses like Parmesan or cheddar.
Storing Unopened Ricotta Cheese
An unopened container of ricotta cheese should be stored in the fridge and will last for about two weeks. The "best by" date on the package is a helpful indication of freshness, but it's not an exact expiration date.
Storing Opened Ricotta Cheese
Once opened, ricotta cheese will last for about one week in the fridge, provided it is stored at a temperature between 35 and 40 degrees Fahrenheit (normal fridge temperatures). It's important to keep the cheese sealed and protected from air exposure, which can cause it to spoil.
Storing Ricotta Cheese in the Freezer
Ricotta cheese can be frozen to extend its shelf life. To freeze ricotta cheese, cut it into portions, drain any liquid, and use paper towels to remove excess moisture. Wrap each portion tightly in plastic wrap, place it in a freezer bag, and store it in the freezer for up to two months. When you're ready to use the frozen ricotta, thaw it in the refrigerator for about 24 hours and use it within two days.
Signs of Spoilage in Ricotta Cheese
It's important to check for signs of spoilage in ricotta cheese, especially if it has been stored for longer than the recommended times. Mould on ricotta cheese can be green, blue, or soft pink, and the cheese may also turn yellowish instead of its regular creamy white colour. A sour or fermented smell is another indication that the cheese has gone bad. When in doubt, it's best to throw the cheese out rather than risk consuming spoiled food.

Can you freeze ricotta cheese?
Yes, you can freeze ricotta cheese. However, it is important to note that freezing ricotta cheese will affect its texture. Ricotta has a high moisture content, and when frozen, the water in it will turn to ice, causing the texture to become more dry, crumbly, gritty, and clumpy. Therefore, previously frozen ricotta cheese is only suitable for certain recipes. It is best to use it in cooked dishes, as the change in texture will be less noticeable. For example, you can use it in a spinach-ricotta quiche or baked ziti with sausage.
If you are freezing an unopened tub of ricotta cheese, you can simply mark it with the date and place it in the freezer. However, if you are freezing leftover ricotta cheese, it is recommended to remove excess moisture by pressing the cheese with paper towels before wrapping it tightly in plastic wrap and placing it in an airtight container or freezer bag. Label the container or bag with the date, and place it in the freezer for up to two months.
To thaw frozen ricotta cheese, transfer it to the refrigerator and allow it to soften for about five to six hours. Do not thaw it at room temperature, as this can lead to bacterial contamination. Once thawed, stir the ricotta well to achieve the best possible consistency. Previously frozen ricotta cheese should be consumed within two to three days and should not be refrozen, as this will further deteriorate the texture.

What are some substitutes for ricotta cheese?
Ricotta cheese is a soft, fresh Italian cheese with a creamy, fluffy texture and a mild, milky flavour. It is used in both sweet and savoury dishes, including lasagna, pasta, cakes, pancakes, and dips. If you're out of ricotta cheese or want to try something different, there are several substitutes that can be used in its place. Here are some options:
- Cottage Cheese: Cottage cheese has a similar flavour to ricotta but is runnier and less creamy. However, blending or processing it can help achieve a smoother texture similar to ricotta. It is best suited for savoury dishes as it is saltier and tangier.
- Greek Yogurt: Greek yogurt is thicker and more strained than regular yogurt, making it a good substitute for ricotta in terms of consistency. It works well in recipes where ricotta is used for its creamy texture, such as sauces.
- Sour Cream: Sour cream has a very different texture from ricotta, but it can be used as a substitute in dishes where cheese is not the main ingredient. It is best suited for dips, baked goods, or dishes with other strong flavours.
- Cream Cheese: Cream cheese is denser and richer in flavour than ricotta, but it can still be used as a substitute, especially in salads and spreads.
- Silken Tofu: Silken tofu, when processed, can be a good vegan substitute for ricotta in dishes like lasagna or pasta. It absorbs flavours well and is high in protein.
- Goat Cheese: Fresh goat cheese, also known as Chevre, is a suitable substitute for ricotta, especially in savoury dishes like meatballs. It has a higher salt content, so adjust the seasoning accordingly.
- Mascarpone: Mascarpone is an Italian cheese that is more tart and flavourful than ricotta. It works well as a substitute in sweet dishes like cannoli, tiramisu, and cheesecake. Thin it out with cream if needed.
Remember, when substituting, consider the flavour, texture, and intended use of the cheese in the specific dish to achieve the best results.
