Mint Simple Syrup Recipe

Fresh, cooling, and incredibly versatile, this homemade mint simple syrup is one of those simple recipes that is good in SO many things, I honestly am shocked it took me so long to include in my simple syrup collection.  Stir it into iced coffee, mix it into lemonade, flavor your favorite cocktails, or sweeten homemade tea – this mint syrup adds the perfect refreshing touch.

And if you’ve never made homemade simple syrup before, don’t worry—it’s surprisingly so, so easy! The magic of three simple ingredients and about 15 minutes gives you a fresh mint syrup that tastes far better than anything store bought.

Unlike some mint syrup recipes that simmer the mint directly with the sugar, this method steeps the mint after the sugar has dissolved. This helps preserve that fresh mint flavor without becoming bitter or overly grassy.

What Is Mint Simple Syrup?

Mint simple syrup is a homemade flavored syrup made by dissolving sugar into water and infusing it with fresh mint leaves.

Ingredients You’ll Need

• Water – Water forms the base of the syrup and helps dissolve the sugar
• Granulated Sugar – Regular white sugar gives the syrup its classic sweetness while allowing the mint flavor to shine
• Fresh Mint Leaves – Fresh mint creates the best flavor. Spearmint is the most common option, but peppermint can also be used for a stronger cooling flavor.

How to Make Mint Simple Syrup

Step 1: Dissolve the Sugar

Heat over medium heat, stirring occasionally, until the sugar fully dissolves. The mixture will go from opaque to clear.

Step 2: Add the Mint

Once the sugar has dissolved, remove the saucepan from the heat and stir in:

• 1 packed cup fresh mint leaves

Lightly press the mint leaves down into the syrup so they are fully submerged.

Step 3: Let the Mint Steep

Allow the mint to steep in the warm syrup for 15–30 minutes, depending on how strong you want the mint flavor.

Step 4: Strain

Pour the syrup through a fine mesh strainer to remove the mint leaves.

Step 5: Store

Transfer the syrup to a mason jar or airtight container and refrigerate until ready to use.

Why This Method Creates Better Mint Syrup

One of the most common mistakes when making mint syrup is simmering the mint leaves directly in the sugar water. While it may seem like it would create a stronger flavor, prolonged heat can actually make fresh herbs taste bitter or dull.

By dissolving the sugar first and then steeping the mint in the hot syrup, you extract the fresh mint flavor while preserving its bright, refreshing taste. It’s the same technique I use in my strawberry mint simple syrup recipe and one of the easiest ways to create a smooth, well-balanced homemade syrup.

What Color Should Mint Simple Syrup Be?

If you’ve never made homemade mint simple syrup before, you might be surprised that it isn’t bright green—or completely clear. Most mint simple syrups are a very pale green, light golden, or slightly yellow-green color.

As the mint leaves steep in the warm syrup, they release natural oils, flavor compounds, and small amounts of plant pigments (chlorophyll). These compounds give the syrup its signature mint flavor while also creating a subtle tint. Because the leaves are added after the sugar has dissolved, they don’t release enough chlorophyll to turn the syrup a deep green color, but they do add enough natural plant material to keep it from remaining crystal clear.

A light green or slightly golden tint is completely normal and a sign that your syrup is flavored naturally with fresh mint rather than artificial coloring. While many store bought mint syrups are dyed bright green, homemade mint simple syrup typically has a much more subtle, natural appearance.

Tips for the Best Mint Syrup

Use Fresh Mint – Fresh mint gives the cleanest and brightest flavor. Garden mint works especially well if you have some growing at home.

Don’t Boil the Mint – Adding the mint after the sugar dissolves helps keep the syrup tasting fresh rather than bitter.

Adjust the Strength – For a stronger mint flavor, simply let the mint steep longer before straining.

Store in Glass – Glass jars or bottles help preserve freshness and flavor.
