When Does Vinaigrette Go Bad?

If kept in the refrigerator, a good guideline for homemade salad dressing is two weeks for a simple vinaigrette and about one week for dressings that contain dairy or fresh herbs. Dressings containing raw garlic should be eaten within a few days because of the risk of botulism.

How can you tell if vinaigrette is bad?

How can you tell if opened balsamic vinaigrette salad dressing is bad or spoiled? The best way is to smell and look at the balsamic vinaigrette salad dressing: if the salad dressing develops an off odor, flavor or appearance, or if mold appears, it should be discarded.

Is it OK to eat expired vinaigrette?

But remember that salad dressings, like a lot of other condiments, usually have a best-by date and not a use-by date or expiration date. Because of this distinction, you may safely use salad dressings to compliment your favorite meals even after the best before date has lapsed.
