Storing Opened Mascarpone Cheese: How Long Does It Last?

Mascarpone is a rich, creamy Italian cheese with a high-fat content, giving it a soft, buttery texture. It is a versatile ingredient used in both sweet and savoury dishes. However, its high moisture content means it can spoil more quickly than hard cheeses if not stored correctly. So, how long does opened mascarpone cheese last? When stored properly in the refrigerator, an opened container of mascarpone can last up to a week.

How to store mascarpone cheese

Mascarpone cheese is a soft Italian cream cheese with a high fat content. It is a perishable food item and does not stay fresh for long, so it's best to buy only what you need.

Storing Mascarpone Cheese in the Fridge

Mascarpone cheese should be kept in the fridge at all times, even if the package is unopened. It is not shelf-stable like aged, hard cheeses. In the fridge, it will last until its best-by date if unopened. Once opened, it will last for around one week. To prolong its life, it should be stored in an airtight container or tightly wrapped in plastic wrap to prevent it from picking up odors from other foods in the refrigerator.

Freezing Mascarpone Cheese

You can also freeze mascarpone cheese. Place it in an airtight container and leave it in the freezer for up to four months. When you need to use it, leave it to thaw overnight in the fridge. If the cheese splits, simply mix it with a fork or a hand-mixer until it has the right consistency. However, freezing mascarpone may affect its texture and flavour, so it is best suited for cooked dishes like sauces, soups, and casseroles, rather than desserts like tiramisu.

Signs of spoilage

Mascarpone is a rich, creamy Italian cheese with a high-fat content. It is perishable and can spoil quickly if not stored correctly. Here are some signs of spoilage to look out for:

Odor

A strong indicator that your mascarpone has gone bad is an off, sour, or unpleasant smell. Mascarpone has a sweet, milky scent when fresh, so any deviation from this fresh dairy aroma could mean it has spoiled.

Texture

If the smooth, creamy texture of the mascarpone has changed, it may be a sign of spoilage. Look for lumps or separation in the cheese, which indicates that it is no longer safe to consume.

Color

Any discoloration or yellowing of the mascarpone is a sign that it has gone bad. Mascarpone should be ivory-colored or white, so any changes in color could mean that bacteria have started to grow.

Mold

If you see any mold growing on the surface or edges of the mascarpone, discard it immediately. Mold is a sure sign of spoilage and can be harmful if consumed.

Taste

Although it is not recommended to taste spoiled food, a sour or off taste can confirm that the mascarpone has gone bad. A bitter flavor could also indicate that the mascarpone is too old.

It is important to note that proper storage of mascarpone is crucial to maintaining its freshness and preventing spoilage. It should be stored in the coldest part of the refrigerator, in an airtight container, and away from strongly scented foods.

Freezing mascarpone

Mascarpone is a soft, buttery Italian cheese with a high fat content. It is often used in desserts such as tiramisu, but it can also be used in savoury dishes like risotto and pasta sauces.

Mascarpone can be frozen for up to four months. To do so, place it in an airtight container and store it in the freezer. When you are ready to use it, take it out of the freezer and leave it in the fridge to thaw overnight.

It is important to note that freezing and thawing mascarpone will affect its texture and it may separate, becoming grainy or curdled. If this happens, you can try to mix it with a fork or a hand-mixer to restore its consistency. However, it will not return to its original state. Therefore, it is best to use thawed mascarpone in cooked dishes rather than as a main ingredient or on its own.

How to tell if mascarpone is bad

Mascarpone is a soft, white, creamy Italian cheese with a slightly sweet and acidic taste. It is a perishable food item that should be kept in the fridge at all times, even if the package is unopened.

• Change in colour and texture: Fresh mascarpone is ivory or white in colour. When it goes bad, it changes to a yellowish, hard colour and becomes crumbly.
• Off odour: Mascarpone has a sweet smell when fresh. When it goes bad, it gives off a gross, sour, and foul odour.
• Mold formation: If you see mold growing on the surface of the cheese, discard it immediately.
• Best-before date: It is not recommended to consume the cheese if its best-before date has passed, even if the packaging is sealed.
• Taste: Bad mascarpone will have an awful and sour taste.
• Lumps: Mascarpone should be smooth and creamy. If you see lumps, discard it.

If you notice any of these signs, discard the mascarpone immediately and do not consume it.

Optimal refrigeration conditions

To ensure mascarpone retains its creamy consistency and rich flavor, it should be stored in the fridge at a temperature of 34°F to 38°F. These temperatures are optimal for delaying spoilage without freezing the cheese, which could alter its texture.

Mascarpone should be stored in its original container with a tight-fitting lid to avoid exposure to air, which can dry out the cheese and introduce contaminants. If the original packaging is not resealable, transfer the cheese to an airtight container or wrap it securely in plastic wrap. This practice helps to prevent the absorption of other flavors and odors from the refrigerator.

It is also beneficial to store mascarpone in the main body of the refrigerator rather than the door, where temperature fluctuations are more common due to frequent opening and closing. Keeping mascarpone in the coldest part of the refrigerator, typically at or below 40°F (4°C), is ideal.
