Rosemary simple syrup is a delightful way to add a touch of herbal sweetness to your beverages and desserts. This versatile syrup can elevate cocktails, lemonades, and even baked goods with its aromatic and slightly piney flavor. It's easy to make and stores well, making it a handy addition to your kitchen.
The key ingredient here is fresh rosemary. While sugar and water are common pantry staples, fresh rosemary might not be something you always have on hand. When heading to the supermarket, look for fresh, vibrant green sprigs of rosemary in the produce section. Avoid dried rosemary as it won't impart the same fresh, aromatic quality to the syrup.

Ingredients For Rosemary Simple Syrup Recipe
Water: The base liquid for the syrup, used to dissolve the sugar and extract the flavor from the rosemary.
Sugar: Provides the sweetness and helps to preserve the syrup.
Rosemary: Fresh sprigs add a unique, aromatic flavor to the syrup.
Technique Tip for This Recipe
When making simple syrup, ensure that the sugar is fully dissolved in the water before adding the rosemary sprigs. This helps to avoid any graininess in the final product. Additionally, when simmering the mixture, keep a close eye on the heat to prevent it from boiling too vigorously, which can cause the syrup to become too thick. For a more intense rosemary flavor, you can lightly bruise the sprigs before adding them to the saucepan.

How To Store / Freeze This Recipe
Allow the rosemary simple syrup to cool completely before storing. This ensures that condensation doesn't form inside the storage container, which could dilute the syrup.
Use a clean, airtight container such as a glass jar or a plastic bottle. This helps maintain the syrup's freshness and prevents any unwanted flavors from seeping in.
Label the container with the date of preparation. While the simple syrup can last up to a month in the refrigerator, it's always good to keep track of its age.
Store the container in the refrigerator. The cool temperature will help preserve the flavor and prevent any bacterial growth.
For longer storage, consider freezing the syrup. Pour the cooled syrup into ice cube trays and freeze until solid. Once frozen, transfer the cubes to a freezer-safe bag or container. This method allows you to thaw only the amount you need.
When ready to use, thaw the desired number of syrup cubes in the refrigerator or at room temperature. This ensures that the rosemary flavor remains intact without any degradation.
If you notice any changes in color, texture, or smell, discard the syrup. Freshness is key to maintaining the best flavor in your culinary creations.
How To Reheat Leftovers
- Pour the rosemary simple syrup into a small saucepan.
- Place the saucepan over low heat.
- Stir occasionally to ensure even heating.
- Heat until the syrup is warm but not boiling, about 3-5 minutes.
- Alternatively, you can microwave the syrup in a microwave-safe container.
- Heat in 15-second intervals, stirring in between, until the desired temperature is reached.
- For a more aromatic experience, add a fresh sprig of rosemary while reheating, then remove before serving.
