Once opened, commercially made blue cheese dressing will typically keep for several months, as long as it is refrigerated and handled properly. The precise answer depends on the storage conditions. To maximize the shelf life of opened blue cheese salad dressing, it should be kept refrigerated and tightly covered. An open packet of blue cheese dressing will generally stay at its best quality for about 6 to 9 months, as long as it has been continuously refrigerated, the package is undamaged, and there are no signs of spoilage.
However, it is important to note that the storage time shown for opened blue cheese salad dressing is for best quality only. After this time, the salad dressing's texture, color, or flavor may change, but in most cases, it will still be safe to consume if it has been stored properly. Bad blue cheese dressing will develop an off, sour smell, and you may also notice a change in its color, from white to yellow or a noticeably darker shade. Additionally, if it has been opened for more than a month, it is safer to discard it. Always throw away any dressing that shows signs of mold or has a chunky consistency when it should be smooth.
Homemade blue cheese dressing, on the other hand, will only last for 3 to 5 days in the refrigerator due to its lack of preservatives. To make it last longer, avoid introducing bacteria by not putting anything in the jar, such as a fork or finger, that could transfer bacteria.

How long does homemade blue cheese dressing last?
Blue cheese is a popular salad dressing and dip known for its sharp, tangy taste. It is made by combining crumbled blue cheese with ingredients such as mayonnaise, sour cream, buttermilk, garlic, and various herbs and spices.
Homemade blue cheese dressing, due to its lack of preservatives, typically lasts between 3 and 10 days in the fridge, depending on the ingredients used and the presence of vinegar, which may prolong its shelf life. It is recommended to keep the dressing tightly covered and refrigerated to maximize its shelf life. To be on the safe side, it is best to consume the dressing within 5 to 7 days, as small things like using a pre-crumbled blue cheese versus crumbling a solid wedge yourself can introduce more bacteria and impact its longevity.
It is important to note that the quality of the blue cheese used in the recipe can also affect its shelf life. Using a quality blue cheese will likely result in a longer-lasting dressing compared to using a regular grocery store variety. Additionally, adding a squeeze of lemon juice not only enhances the flavor but may also help to extend its freshness.
Bad blue cheese dressing will develop an off, sour smell, and its color may change from white to yellow or darker shades. If the dressing has been opened for more than a month, it is safer to discard it.
