Freeze fresh herbs in olive oil! Add the cubes to pasta/potato dishes, soups, or roasting onions, garlic, & veggies; These have a six month freezer life and do need to be stored separately to preserve individual flavors of the herbs.
Herbs All Year - The best way to preserve herbs is to freeze them in oil or butter. Packed in flat, thin layers in heavy-duty zip-top bags, frozen herb butters and oils are easy to store. Use herbs preserved in oil the same way as fresh herbs.
