What Is Rosemary Simple Syrup?

Rosemary simple syrup is a sweet, flavored syrup infused with the aromatic oils of rosemary. It combines the sweetness of sugar with the earthy, pine-like flavor of rosemary, creating a refreshing herbal sweetener that works beautifully in both drinks and desserts.

Ingredients You’ll Need

1 cup water
1 cup granulated sugar
¼ cup fresh rosemary leaves (about 2–3 sprigs)

Step-by-Step Instructions

Step 1: Combine Ingredients

In a small saucepan, add 1 cup of water, 1 cup of sugar, and ¼ cup of rosemary leaves.

A mason jar filled with a clear, yellowish liquid and a fresh sprig of rosemary. A bowl of sugar and a glass of water are next to it on a wooden surface, surrounded by more rosemary sprigs.

Step 2: Bring to a Boil

Place the pan over medium heat and stir until the sugar completely dissolves.

Step 3: Simmer

Let the mixture simmer gently for about 1–2 minutes to release the rosemary flavor.

Step 4: Steep the Rosemary

Remove the saucepan from heat and allow the syrup to steep for 20–30 minutes. This step helps the rosemary fully infuse into the syrup.

Step 5: Strain and Store

Strain the syrup through a fine mesh sieve into a clean, sterilized glass jar. Discard the rosemary leaves.
