The most efficient and versatile way to freeze basil is by making basil cubes. You can toss them into soups at the last-minute for some fresh flavor.
- Basil leaves, washed
- olive oil
Add basil to the food processor or chop with a knife and add enough oil to coat the leaves to make a thick paste. Spoon the mixture into ice cube trays, freeze, and when frozen pop them out and transfer to well-sealed freezer bags.
