Lasagna is a comfort food for many, but the smell of ricotta cheese can be off-putting for some. While ricotta cheese has a very mild odour, it can sometimes smell sour, indicating that it has gone bad. To prevent this from happening, it is important to store ricotta cheese properly and use it promptly, as it only stays fresh for about one to two weeks. If you notice any unpleasant odours or changes in appearance, it is best to discard the cheese and start with a fresh batch to ensure your lasagna tastes and smells delicious.

What You'll Learn
Use cottage cheese instead of ricotta
While ricotta is a popular choice for lasagna, you can easily substitute it with cottage cheese. Cottage cheese has a very similar light and creamy flavour to ricotta, making it a great base for a cheesy faux-béchamel mixture with herbs, Parmesan cheese, and cream.
Cottage cheese is a better option than ricotta because it can withstand higher temperatures. Ricotta can curdle and become grainy at high temperatures, while cottage cheese retains its creamy consistency even after being baked in the oven for a long time. This makes cottage cheese a great choice for lasagna, which requires baking at high temperatures.
When substituting cottage cheese for ricotta, you can use an equal amount of cottage cheese in most lasagna recipes that call for ricotta. To avoid a watery lasagna, it is recommended to use regular, full-fat cottage cheese instead of low-fat cottage cheese.
You can also add a bit of heavy cream to the cottage cheese mixture for added creaminess, although this is optional. Some people prefer to bake lasagna with just the cottage cheese mixture without adding cream, and it tastes great both ways.
So, if you're looking for a substitute for ricotta in your lasagna, cottage cheese is a great option that will result in a delicious and creamy dish.

Throw out ricotta if it smells sour
Ricotta cheese is a popular ingredient in many dishes, including lasagna. It is loved for its mild, soft, and creamy texture and taste. However, it is a highly perishable product and can go bad quickly.
When ricotta cheese starts to spoil, it will exhibit certain signs that indicate it is no longer safe to consume. One of the most notable signs is a change in smell. Fresh ricotta has a subtle aroma, mostly reminiscent of milk. However, when it turns sour, it emits an unpleasant odor that can be described as sour or fermented. If your ricotta smells sour, it is a clear indication that it has gone bad, and the best course of action is to discard it.
The sour smell in ricotta cheese could be due to several reasons. It may be caused by using sour milk during the cheese-making process, as some people do this to prevent milk waste. However, even after turning the sour milk into ricotta, the unpleasant odor may persist, indicating that it is not safe for consumption. Additionally, ricotta cheese that has been stored for an extended period, beyond its "use-by" date, is more likely to develop a sour smell, indicating spoilage.
Apart from the smell, there are other signs to look out for that indicate ricotta cheese has gone bad. Any visible mold growth on the surface of the ricotta is a sure sign of spoilage, and the entire container should be discarded as some molds produce harmful toxins. Changes in appearance, such as a yellowish or brownish discoloration, or the presence of a watery layer on top of the cheese, are also indicators that the ricotta has spoiled.
In conclusion, when it comes to ricotta cheese, freshness is key. If your ricotta smells sour or exhibits any signs of spoilage, it is best to err on the side of caution and throw it out. By doing so, you can avoid potential foodborne illnesses and ensure the quality and safety of your dishes, especially when preparing beloved meals like lasagna.

Don't use ricotta that has mould on it
When preparing lasagna, it's important to ensure that the ingredients, especially cheese, are fresh and safe to consume. Ricotta cheese, in particular, can spoil quickly due to its high moisture content.
If you notice any mould on your ricotta cheese, it's crucial to discard it immediately. Unlike harder cheeses, where mould can be cut off and the remaining cheese safely consumed, mould on ricotta indicates that the entire container is contaminated with mould spores, some of which can produce harmful toxins. Therefore, it is unsafe to consume ricotta cheese that has mould on it, and it should be thrown away.
Additionally, pay attention to other signs of spoilage in ricotta cheese. Changes in appearance, such as a yellowish or brownish discolouration or the presence of a watery layer on top, indicate that the ricotta has gone bad. Similarly, if the ricotta smells sour or fermented, it has likely spoiled and should be discarded.
To prevent ricotta cheese from spoiling, proper storage is essential. Always store ricotta in the refrigerator at 40 degrees Fahrenheit or cooler, and ensure it is covered. Even with careful handling, ricotta has a limited shelf life, so it's best to use it promptly. According to the U.S. Department of Agriculture, an opened package of ricotta should be discarded if it has been in the fridge for longer than two weeks.
In summary, when preparing lasagna, do not use ricotta cheese that has mould on it. Mould on ricotta indicates spoilage, and consuming it can be unsafe due to the presence of harmful toxins. Always check the appearance, smell, and expiration date of ricotta before using it in your lasagna to ensure food safety and the best flavour.

Store ricotta covered in the fridge
To store ricotta cheese in the fridge, it is important to keep it covered. This helps to maintain its freshness and prevents it from absorbing any odours from other foods in the fridge. It is best to store it in an airtight container, placed towards the middle of the fridge, where temperatures are more consistent. The ideal temperature range for storing ricotta is between 35 and 40 degrees Fahrenheit.
Opened ricotta cheese should be consumed within a week or two. However, some sources suggest that it can last up to three or four days while maintaining its best quality. After this time, the ricotta may start to taste “different” and develop a sour odour. Therefore, it is recommended to use it promptly and keep it covered in the fridge to prolong its freshness.
If you wish to store ricotta for a longer period, freezing is an option, but it is important to note that freezing can alter its texture. To freeze ricotta, transfer it to an airtight container or a freezer bag, and label it with the date. Frozen ricotta can be stored for up to three months. When you're ready to use it, thaw it overnight in the fridge or until it reaches the desired consistency.
To ensure food safety, it is crucial to check for any signs of spoilage before consuming ricotta cheese. If the ricotta has developed an unpleasant or sour odour, changed colour (yellowish or brown), or has a layer of water on top, it should be discarded. Additionally, if mould is present, the entire container should be thrown away, as mould spores may have infiltrated the cheese. Always trust your senses and, if in doubt, dispose of the ricotta cheese.

Use ricotta promptly after opening
Ricotta cheese is a soft, mild cheese with a high moisture content. This means that it spoils more quickly than hard cheeses. An unopened container of ricotta will stay fresh for two to four weeks, and may be good for a week or two past this date. However, once opened, ricotta cheese should be used promptly and will only last for one to two weeks in the refrigerator. To be on the safe side, discard ricotta cheese that has been in your fridge for longer than two weeks after opening it. If you can't remember when you bought the ricotta, throw it out.
The freshness of ricotta cheese can be determined by its appearance and smell. If the ricotta has gone yellowish or brown, or if there is a layer of water sitting on top of the cheese, this is an indicator that your ricotta has spoiled. Additionally, if your ricotta begins to smell sour, this is a sign that it has gone bad. Some molds produce harmful toxins, so if you notice any mold growth on your ricotta, it is important to throw it away.
To prolong the freshness of ricotta cheese, it should always be stored covered and in the refrigerator at 40 degrees Fahrenheit or cooler. When handling ricotta, use a clean serving spoon to scoop out a portion and refrigerate promptly after use.
