Can you freeze fresh herbs?

Serious Eats Article Says Yes

Yes. The texture obviously changes. You can freeze in water or olive oil. Most suggestions are to freeze in olive oil ice cubes. Some herbs can be dried and crumbled for future use.

Sometimes, I grind fresh rosemary, put it in a ziplock bag in the fridge and use it from there.

If you have a lot of basil, you can make pesto and freeze that.

If you have the stems, you can put them in water and root them. I usually put them in glass jars on the windowsill. I've planted them before, but I usually just keep using them. The basil will grow more leaves. I've kept it fresh for weeks that way when I have a big bunch of it.
