Frozen herbs: One year
“Herbs can go off very quickly, so prior to that happening, chop them up finely, put them in an ice cube tray, and add either water or olive oil,” advises Nikki Sharp, author of Meal Prep Your Way to Weight Loss.
“Then, when you’re ready to use the herb, pop it out and you can heat the olive oil up in a pan while sautéing your cilantro, for example. Alternatively, add mint and water then throw into smoothies.” This method allows herbs to last for up to a year, Sharp says.
