Warm your olive oil. Pour the olive oil into a small sauce pan and heat it over a low flame until it is warm. The warming process should take just a few minutes. It should be warm, not hot. High temperatures destroy the healthy properties in olive oil.
Put rosemary into a bottle, remember that a little bit of rosemary goes a long way, so there is no need to stuff the bottle full of this herb. Pour the warm olive oil into the bottle. Put the bottle aside to cool. Seal the bottle with a lid or a cork. Set the bottle in a dry, cool place with no direct sunlight for at least one week.
You can strain the rosemary out of the oil. Many people leave the rosemary leaves in the oil for a decorative touch. If you prefer to strain the olive oil, simply pour the oil through a strainer into a clean jar or bottle.
Enjoy your rosemary-infused olive oil. This oil is perfect for drizzling on salads and fresh bread. You can use the oil to flavor potatoes and pasta dishes. You can also try marinating chicken and fish in the oil for a little extra flavor.
