How Long Does Pesto Last After Open?

Once opened, store-bought pesto typically lasts about 5 to 7 days in the refrigerator if kept in an airtight container. Homemade pesto may have a shorter shelf life, generally around 3 to 5 days. To maximize freshness, always use clean utensils to scoop out pesto and consider freezing any unused portions for longer storage. Always check for signs of spoilage, like off smells or mold, before use.
