About this Rosemary Syrup recipe
They say scent memories are some of the strongest. I have to agree because I will never forget the smell of the rosemary bushes outside my aunt’s house. She has an entire garden bed dedicated to this fragrant herb — smelling it always makes me think of her.
Its earthy flavor is stunning It’s also wonderful in everything from savory dishes, from brie bites to pizza dough to pasta dishes. And its herbaceous scent and flavor is equally welcome in sweet recipes, like shortbread cookies and cocktails!
Rosemary is awesome as an infusion agent. It’s key for making many infused cocktails. You can even use it to infuse your own rosemary oil to cook with and finish dishes.
The best way to bring rosemary flavor to a cocktail is by using a homemade rosemary simple syrup. I love using rosemary-infused syrup in drinks like my rosemary mule.
Made with just three ingredients, this fragrant syrup is a welcome infusion that will elevate your drinks with herbal flavor. The best part is you can make it as mild or intense as you like.

Why you’ll love this recipe
Simple syrups are just that — simple! Here’s why we love this one:

- This syrup comes together in under 30 minutes. Who has time for more than that?!
- And it’s so good in drinks from lemonade to cocktails!

What is simple syrup?
Also called sugar syrup, simple syrup is a homemade sweetener for drinks and sweet treats. It’s as simple as its name denotes — all you need is equal parts sugar and water.
It is easy to flavor simple syrup with infusions from herbs, fruits and spices, like this cinnamon simple syrup, and when used in drinks the syrup imparts this additional flavor.
There are a few main uses for simple syrup:
- Simple syrup is called for in many cocktail recipes, like an old-fashioned or a margarita, and non-alcoholic drinks like lemonade. It is one of the easiest ways to sweeten cold drinks because regular sugar dissolves too slowly.
- It is also often used in hot tea and coffee drinks, like lattes and cappuccinos, because the liquid form doesn’t take as much stirring to blend into the
drink to dissolve pure sugar. - Cake bakers sometimes use simple syrup to flavor and moisten cakes before frosting them or before refrigerating or freezing the layers. It can also be used to flavor fruit salads.

Tools & equipment
Making simple syrup doesn’t require anything you don’t already have in your kitchen! All you really need is a medium saucepan and a wooden spoon to do the infusion, and a wire-mesh strainer, colander or slotted spoon to strain out the herbs.
Plus, you’ll need a vessel to store it in. You can store it in a bottle, mason jar or other airtight container and store it in the refrigerator or use it in cocktails, iced tea and coffee immediately!

Ingredients
Here’s are the simple ingredients you’ll need to pick up at the grocery store to make this easy rosemary syrup:
- sugar: Granulated sugar (white sugar) and cane sugar are my top picks for making my own simple syrup because they create a clear simple syrup which I prefer for most cocktails.
- water: You’ll need as much water as you use sugar. I prefer to use filtered water if possible, especially for syrups since it is one of the main ingredients. (We use this water filter pitcher.)
- fresh rosemary sprigs: Fresh rosemary is best for this recipe, and you can use homegrown or store-bought sprigs.

Substitutions & variations
Switch up the sugar: Brown sugar can be used instead; however, it will give off its caramel color, which is less than ideal for pretty, clear drinks like a mojito. If you like, you can substitute honey to make a rosemary honey simple syrup. Would be so delicious!
Add other herbs or flowers: Lavender flowers or a mix of herbs like mint and thyme would be delicious additions.
Infuse fruits: Add slices of lemon, orange or grapefruit, which go well with rosemary. Cranberries would also be festive for the holidays.
Best rosemary
If you have rosemary growing in your herb garden, feel free to use that! I love having some on hand because they are so hearty and last all year long for summer and winter cooking alike. This syrup is a great way to use up rosemary you may have bought for another recipe, like these rosemary drop biscuits.
Otherwise, fresh rosemary should be available in the produce section of your local grocery store or at your local farmers market. Usually, it is stored in plastic clamshell packaging. You will need about 4 sprigs of fresh rosemary, but more or less is okay.
You can use dried rosemary, but it is more difficult to strain out, so some sediment may remain.
Flavor Tip
Just before dropping it into your syrup infusion, hold a fresh rosemary sprig in one hand and clap your other hand on top of it to “spank” it. This releases essential oils and fragrances from the rosemary leaves for a more aromatic syrup.

How to make Rosemary Syrup
Your rosemary simple syrup will come together in just a few steps:
- Measure equal parts sugar and water. (For example, if you use 1 cup water, use 1 cup sugar.) Combine water and sugar in a small saucepan over medium heat. Stir them together until combined.
- Remove from heat. No need to simmer or boil it! Add your rosemary sprigs while the mixture is hot.
- Let the sprigs steep for 15 minutes, or until the syrup has the strength of rosemary flavor you love. You can even leave the sprigs in overnight to impart more flavor. Use a slotted spoon or fine mesh strainer to remove the sprigs and discard them.
- Let the mixture cool down fully to room temperature, then pour your cooled syrup into a bottle, mason jar or other airtight container and store it in the fridge or use it in cocktails, iced tea and coffee immediately!

Rosemary cocktails
For cocktails, the earthy, botanical flavor of rosemary works with a variety of spirits, from rum to tequila.
Vodka: Try this rosemary Moscow mule which uses the syrup as a great addition to sweet and spicy ginger beer.
Sparkling wine: I use this syrup in this rosemary champagne cocktail which highlights the rosemary with a bubbly, dry prosecco.
Gin: The woodsy flavor of rosemary complements fruit flavors, especially citrus flavors like grapefruit or lemon juice. Try it in a grapefruit rosemary gimlet.
Whiskey: Bourbon and rosemary are a perfect match. Try a pineapple rosemary whiskey smash. At the holidays, make this cranberry rosemary old-fashioned or a smoked old-fashioned.
Herb cocktails: It is the perfect way to change up classic recipes in which other herbs typically shine. Try rosemary instead of or in addition to mint in a classic julep or a mojito.
Non-alcoholic drinks: You can also use rosemary simple syrup to sweeten non-alcoholic drinks. It is an easy way to sweeten coffee drinks, make rosemary lemonade or iced tea or mix it into a boozy cocktail.
Tips & tricks
Here are some tips and tricks for making this recipe:
- You can boil the water first to use in your syrup to eliminate impurities. (I don’t like to boil my syrup. The water evaporates and you’ll end up with a thicker syrup — and less of it.)
- Leftover simple syrup? Try freezing it into ice cube trays.

Can you freeze it?
Susannah says
Hey Lindsey! Yes you can freeze simple syrup. You can do it in an ice cube tray or freeze it another freezer-safe container. Then just put it in the fridge to thaw or let a couple of the cubes melt before mixing with them again. Hope this helps!
