Ricotta cheese is a soft, creamy, and slightly grainy cheese with a mild flavour. It is highly perishable and should be consumed within a week or two of opening. If not consumed within this time frame, ricotta cheese can spoil and develop mould, which can be harmful if consumed. To extend its shelf life, ricotta cheese can be frozen, but this may affect its texture and taste. Therefore, it is recommended to inspect the cheese for any signs of spoilage and consume it promptly to ensure food safety and maintain its optimal quality.

What You'll Learn
Ricotta cheese should be used within a week of opening
Ricotta cheese is a soft, creamy, and slightly grainy cheese with a high moisture content. This means that it spoils quickly and should be consumed within a week of opening. To extend its shelf life, you can store it in an airtight container and press cling film against its surface to minimise air and moisture exposure. Additionally, always use clean utensils when handling the cheese to avoid introducing bacteria.
Even with proper storage, ricotta cheese will only last about a week in the refrigerator. Its high moisture content creates a breeding ground for bacteria, and exposure to air accelerates spoilage. Therefore, it is essential to keep it covered and refrigerated at 40 degrees Fahrenheit or lower.
If you wish to extend the shelf life of ricotta cheese beyond a week, you can freeze it. Freezing ricotta cheese can extend its shelf life to about two months. However, the freezing process may affect its texture, making it dry, crumbly, and grittier. Frozen ricotta cheese is best suited for cooked dishes like sauces, soups, casseroles, lasagna, or quiche, where its altered texture will be less noticeable.
It is important to note that freezing ricotta cheese may not yield the most appetising results. The water in the cheese will separate from the fat, resulting in a clumpy and less smooth product when defrosted. Additionally, freezing and thawing can affect the flavour of the cheese.
To ensure food safety, it is crucial to inspect the ricotta cheese for any signs of spoilage before consumption. If there is any visible mould, discolouration, or a sour odour, discard the cheese immediately. Trust your senses and, if in doubt, throw it out.

It can be frozen to extend its shelf life by 2 months
Ricotta cheese is a soft, creamy, and slightly grainy cheese with a high moisture content. It is highly perishable and should be consumed within a week or two of opening. However, if you wish to extend its shelf life, freezing is an option.
Freezing ricotta cheese can increase its shelf life by up to two months. While freezing does not alter the flavour of the cheese, it does affect its texture. The high moisture content of ricotta means that the water in the cheese will separate from the fat, resulting in a dry, crumbly, and gritty texture after freezing and thawing. Therefore, previously frozen ricotta is best suited for cooked dishes where its altered texture will be less noticeable. Examples of dishes that use cooked ricotta include lasagna, quiche, spinach-ricotta quiche, baked ziti with sausage, ravioli filling, and stuffed zucchini.
To freeze ricotta cheese, start by stirring the cheese with a spoon to ensure even freezing. Next, remove the cheese from its original container and use paper towels to gently press and remove excess moisture. Wrap the cheese tightly in plastic wrap, either as a whole or in individual portions using an ice cube tray for easier thawing. Transfer the wrapped cheese to a freezer-safe bag or an airtight container, ensuring that as much air as possible is removed before sealing. Label the container with the date, then place it in the freezer for up to two months.
When you are ready to use the frozen ricotta, thaw it in the refrigerator for about five to six hours or until completely softened. Do not leave it to thaw at room temperature, as this can lead to bacterial contamination. Previously frozen ricotta should be consumed within two to three days of thawing and should not be refrozen, as this will further deteriorate its texture.

Unopened, it lasts 2-4 weeks in the fridge
Ricotta cheese is a soft, creamy, and slightly grainy cheese with a mild flavour. It is highly perishable due to its high moisture content, which creates a breeding ground for bacteria. Therefore, it is important to store it correctly and check for signs of spoilage.
An unopened container of ricotta cheese will typically last for about two to four weeks in the fridge. The "best-by" date on the package is a helpful indicator, but it is not an exact expiration date. Instead, it suggests the period during which the product will be of peak quality.
Ricotta cheese that has been opened will only stay fresh for about one to two weeks, according to various sources, including the U.S. Department of Agriculture. To ensure food safety, it is recommended to discard ricotta cheese that has been opened and kept in the refrigerator for longer than two weeks.
If you wish to extend the shelf life of ricotta cheese, you can consider freezing it. Freezing can preserve the cheese for about two months. However, it is important to note that freezing may alter the texture of the cheese, making it dry, crumbly, and grittier. Therefore, it is recommended to use thawed ricotta in cooked dishes where its texture will be less noticeable.

Spoilage signs: mould, discolouration, sour smell, change in texture
Ricotta cheese is a soft, mild-flavoured cheese with a high moisture content. Due to its soft and moist nature, ricotta is more perishable than harder cheeses like Parmesan or Cheddar. An opened package of ricotta will generally last for about a week in the refrigerator, and up to two weeks at most. Beyond this, the cheese will spoil and should be discarded.
Mould: If you spot any mould on the surface of the ricotta cheese, discard it immediately. Unlike harder cheeses, where mould can be cut off and the rest of the cheese consumed safely, mould in soft cheeses like ricotta can penetrate below the surface. Therefore, consuming mouldy ricotta can make you sick. Mould on ricotta can be green, blue, or soft pink.
Discolouration: Fresh ricotta is white in colour. If you notice any discolouration, especially a yellowish or light brown hue, this is a sign of spoilage.
Sour smell: Fresh ricotta has a mild, milky smell. If the cheese develops a sour or fermented odour, it has likely gone bad and should be discarded.
Change in texture: Fresh ricotta has a soft, creamy, and slightly grainy texture. If it becomes dry, crumbly, gritty, lumpy, or watery, it has likely spoiled.
In summary, ricotta cheese is highly perishable and should be consumed within a week of opening, or at most, within two weeks. Always inspect the cheese for any signs of spoilage before consumption, and if in doubt, discard it.

High moisture content means it spoils quicker than harder cheeses
Ricotta cheese is a soft, creamy, and slightly grainy cheese with a mild, milky flavour. It is a versatile ingredient, commonly used in both sweet and savoury dishes. However, ricotta has a high moisture content, which means it spoils much quicker than harder cheeses.
Ricotta's high moisture content creates an environment conducive to bacterial growth, causing the cheese to spoil quickly. This is why ricotta should be consumed within a week or two of opening, while some sources suggest a shorter shelf life of three to seven days. To extend its shelf life, ricotta can be stored in the freezer, but this may alter its texture, making it dry, crumbly, and grittier. Therefore, frozen ricotta is best suited for cooked dishes like sauces, soups, casseroles, lasagna, or quiche, where its altered texture is less noticeable.
The key to preserving ricotta's freshness is to minimise its exposure to air and moisture. Once opened, it should be stored in an airtight container with cling film pressed against its surface, and clean utensils should be used to scoop out the desired amount. Additionally, ricotta should be stored at a constant temperature of 35 to 40 degrees Fahrenheit in the refrigerator.
To determine if ricotta cheese has spoiled, one should look for signs of mould, discolouration, or a change in appearance. Unlike harder cheeses, where mould can be cut off and the remaining cheese consumed safely, mould in soft cheeses like ricotta can penetrate below the surface, making it unsafe to consume even if the visible mould is discarded. A sour or fermented odour is another indication that the ricotta has gone bad and should be discarded.
