1. Dehydrate the Rosemary

It’s highly recommended to dehydrate the rosemary sprigs before using them to reduce the risk of bacteria. Before doing so, chop the rosemary to fit the bottle where you’ll be storing the infused olive oil - then wash, dry, and dehydrate the rosemary.

You can dehydrate the herb in two ways:

  • Dehydrate in an Oven

Line a baking sheet with parchment paper and place the sprigs on it. Turn the oven down to its lowest temperature. Leave the rosemary in the oven for 1-2 hours or until the stem is entirely dry and can be snapped.

  • Dehydrate in a Dehydrator

Spread the rosemary sprigs on the dehydrator trays and warm them at 95 degrees for about 8 hours. Check to see if the stem breaks easily. This is especially important to confirm that the rosemary is dry.

Once you learn how to make dried rosemary for the oil, it’s time to prepare the infused olive oil itself.

2. Add Dried Rosemary to Olive Oil

Place the dried rosemary sprigs in a pint-sized Mason jar and fill it with two cups of olive oil. Ensure all the utensils you use to prep and store your oil are clean and dry.

3. Store for Two Weeks

Garlic, rosemary, and olive oil

Close the jars tightly and let them sit for approximately two weeks in a warm place. This step allows the rosemary to infuse the olive oil. During this period, all the delicious compounds of the herb will be released into the olive oil. Don’t let any water into the infusion because this can cause bacteria to form.

4. Strain and Enjoy

Strain out the rosemary after two weeks to have an aromatic infused olive oil. You can enjoy this delicious oil in any of your favorite recipes or give it to a special loved one. When gifting, place an extra sprig or two of dried rosemary in a decorative bottle and pour the infused oil over it. Close the lid tightly and add a label. Don’t forget to include an expiration date of about three months from the infusion date.
