Blue cheese dressing is a delicious addition to any salad, but it's important to know when it's time to toss it out. Proper storage is key to maintaining freshness and extending the shelf life of blue cheese dressing. Blue cheese dressing typically lasts about 1 to 2 months in the refrigerator once opened, but several factors indicate when it has gone bad. These include changes in smell, appearance, texture, and taste. To maximize its shelf life, it should be stored in a cool, dry area before opening and in the refrigerator after opening, always using clean utensils and avoiding cross-contamination. Freezing blue cheese dressing is another option for long-term storage, though it may alter the texture slightly.

What You'll Learn
Blue cheese dressing storage
Blue cheese dressing is a tasty addition to many dishes, but it's important to store it correctly to maintain freshness and avoid spoilage. Here are some detailed instructions on how to store your blue cheese dressing:
Refrigeration
Always keep your blue cheese dressing refrigerated. This is the best way to preserve its freshness and extend its shelf life. Return the dressing to the refrigerator immediately after use to prevent temperature fluctuations that can hasten spoilage. Blue cheese dressing typically lasts about 1 to 2 months in the refrigerator once opened. However, commercially packaged blue cheese dressing can last about 6 to 9 months in the refrigerator.
Clean Utensils and Containers
Use clean utensils when serving or scooping out the dressing to prevent contamination. Avoid returning unused portions to the original container to prevent the introduction of contaminants. It is also important to use airtight containers or heavy-duty freezer bags if you plan on freezing your dressing for long-term storage.
Signs of Spoilage
It is crucial to regularly check your blue cheese dressing for spoilage to avoid consuming spoiled or unsafe food. Signs of spoilage include an unpleasant odor (sour or rancid), mold growth, discoloration (yellow or brown tints), and texture changes (separation, chunky, or watery consistency). If you notice any of these signs, discard the dressing immediately.
Freezing
Freezing is an effective way to extend the shelf life of blue cheese dressing. To freeze, portion the dressing into smaller containers or freezer bags, label with the date, and place in the freezer immediately. When you're ready to use the frozen dressing, thaw it in the refrigerator overnight and stir well to restore its consistency.
Storage at Room Temperature
If you are storing an unopened package of blue cheese dressing, it is best kept in a cool, dry area. Properly stored, it will generally stay at its best quality for about 12 to 18 months.

Signs of spoilage
Blue cheese dressing can indeed go bad, and it's important to know the signs of spoilage to avoid consuming it. The shelf life of blue cheese dressing depends on whether it's homemade or store-bought, opened or unopened, and the storage conditions.
Off Odors or Ammonia-like Smell
The most commonly cited sign of spoilage in blue cheese dressing is an off odor or a sour smell. If the dressing smells sour, stale, or just "funny," it's best to discard it. This is because the blue mold in the cheese produces ammonia, which can give off an ammonia-like smell as the dressing spoils.
Mold Growth
Visible mold growth is another clear indication that your blue cheese dressing has gone bad. Even if it's just a small amount, it's best to throw away the entire bottle. The mold may produce toxins that can be harmful to consume.
Color Changes
Color changes can also indicate spoilage in blue cheese dressing. Fresh blue cheese dressing is typically creamy white or slightly off-white with blue-green streaks from the blue cheese crumbles. If the dressing turns yellow, it could indicate that the fats have separated, and browning is a more serious sign of spoilage.
Chunky Consistency
A change in texture, such as a chunky consistency instead of a smooth one, could be another sign that your blue cheese dressing has gone bad. This could be due to the separation of oils and solids or the growth of bacteria.
Discoloration
Discoloration or a change in color, especially if it's a significant change, could be a sign of spoilage. This could be due to oxidation or the growth of bacteria.
It's important to note that even if the blue cheese dressing doesn't show any of these signs of spoilage, it's still best to follow the recommended shelf life and storage guidelines. Proper storage, such as refrigeration and tightly sealing the container, can help extend the shelf life and maintain the quality of the dressing.

How to identify mould
Proper storage is key to maintaining the freshness of blue cheese dressing and extending its shelf life. To maximise the shelf life of opened blue cheese salad dressing, it should be kept refrigerated and tightly covered. Blue cheese dressing that has been continuously refrigerated will generally stay at best quality for about 6 to 9 months.
However, despite proper storage, blue cheese dressing can still go bad. To identify mould in blue cheese dressing, there are a few signs to look out for:
- Visual Changes: Keep an eye out for any signs of mould growth or unusual discolouration. Blue cheese dressing may develop mould that appears as grey veins with specks of blue, which is different from the blue veins of the cheese itself.
- Texture Alterations: A change in consistency can indicate spoilage. If the dressing becomes unusually thick, lumpy, or excessively watery, it may be past its prime.
- Odor: Pay attention to any sour or off smells that deviate from the dressing's typical tangy aroma. A rancid or unpleasant odour could indicate spoilage.
- Taste: If the dressing has a bitter or unpleasant taste, it has likely gone bad and should not be consumed.
If you notice any of these signs, it is best to discard the dressing. Consuming spoiled blue cheese dressing can pose health risks, so it is important to regularly check its condition, especially if it has been stored for an extended period.

Extending shelf life
Proper storage is key to extending the shelf life of blue cheese dressing. To maximize its shelf life, it should be stored in a cool, dry, and dark place, away from direct sunlight or heat sources. Once opened, it should be refrigerated immediately and stored in an airtight container to prevent exposure to air and bacteria, which can cause spoilage. It is also important to use clean utensils when serving the dressing and to not return unused portions to the original container to prevent contamination.
The shelf life of blue cheese dressing can be further extended by freezing it. This can alter the texture slightly, but it remains a good option for long-term storage. To freeze blue cheese dressing, portion it into smaller containers or heavy-duty freezer bags, label them with the date, and place them in the freezer immediately to preserve freshness. When you are ready to use the frozen dressing, thaw it in the refrigerator overnight and stir well to restore its consistency.
Additionally, it is important to regularly check the condition of blue cheese dressing, especially if it has been stored for an extended period. Signs of spoilage include mold growth, discoloration, a sour or off smell, and a bitter or unpleasant taste. If any of these signs are present, it is best to discard the dressing as consuming spoiled blue cheese dressing can pose health risks.
By following these guidelines and properly storing your blue cheese dressing, you can extend its shelf life, reduce waste, and ensure that it retains its freshness, flavor, and texture for as long as possible.
