This vibrant basil lemonade transforms ordinary lemon water into something truly special. The aromatic basil infuses the classic summer drink with a sophisticated herbal note that keeps everyone coming back for refills.
I first made this when my herb garden was overflowing with basil and I needed something besides pesto to use it all. Now it's requested at every summer gathering I host, with friends asking for the recipe before they even leave.
Ingredients
- Fresh basil leaves the star ingredient that transforms ordinary lemonade with its aromatic oils
- Granulated sugar creates the sweet base that balances the tartness
- Fresh lemons always use fresh juice for the brightest flavor profile
- Water dilutes to the perfect strength while keeping all flavors in balance
Step-by-Step Instructions
- Muddle the Aromatics
- Combine sugar and basil leaves in a medium saucepan and press firmly with a wooden spoon to release the essential oils from the basil leaves. This bruising action is crucial for extracting maximum flavor from the herbs.
- Create the Simple Syrup
- Add 2 cups water to the sugar-basil mixture and heat over medium heat while stirring frequently. Continue cooking until all sugar crystals have completely dissolved, creating a clear syrup with green flecks of basil.
- Infuse and Cool
- Remove the saucepan from heat and allow the basil to continue steeping in the syrup until it reaches room temperature. This slow cooling process allows the basil oils to fully permeate the syrup, creating a deeper flavor profile.
- Strain and Combine
- Pour the cooled basil syrup through a fine mesh strainer into a large pitcher. Discard the basil leaves after pressing gently to extract any remaining syrup. Add the remaining 4 cups water and freshly squeezed lemon juice to the pitcher.
- Mix and Serve
- Stir the mixture thoroughly to ensure even distribution of flavors. Pour over ice-filled glasses and garnish with fresh basil leaves and lemon slices for an elegant presentation.

The bright green color that develops during the muddling process always makes me smile. My grandfather, who was an avid gardener, would have loved this recipe. He taught me that herbs should never be wasted, and this lemonade honors his practical wisdom by turning excess basil into something extraordinary.
Make It Your Own
This basil lemonade provides a wonderful base for customization. For an adult version, add a splash of vodka or white rum to create an instant signature cocktail. For a sparkling variation, substitute some of the water with club soda or sparkling water just before serving. The carbonation adds a festive touch that works beautifully for celebrations.
Perfect Pairings
This herbal lemonade complements summer meals beautifully. Serve alongside grilled chicken, fish tacos, or Mediterranean dishes where the basil notes create flavor harmony. It also pairs wonderfully with spicy foods, as the sweet-tart combination helps cool the palate between bites of heat-forward dishes.
Storage Tips
Store any leftover lemonade in a glass container with a tight-fitting lid. The flavor actually improves after sitting for a few hours as the ingredients meld together. While best consumed within three days, you can freeze the strained basil syrup separately in ice cube trays for quick single servings throughout summer.
Recipe FAQs
- → Can I make basil lemonade ahead of time?
Yes, you can prepare basil lemonade up to 2 days ahead. Store it covered in the refrigerator. The flavor actually improves as it sits, allowing the basil notes to fully develop. Give it a good stir before serving over fresh ice.
- → What can I substitute for fresh basil?
If fresh basil isn't available, you can substitute other herbs like mint, lemon verbena, or thyme. Each will create a different flavor profile. You could also use 2-3 tablespoons of dried basil in a pinch, though the flavor won't be as vibrant as with fresh leaves.
- → How can I make this basil lemonade less sweet?
To reduce sweetness, start by using 3/4 cup of sugar instead of a full cup. You can also increase the lemon juice by adding an extra 1/4 cup. Alternatively, make the drink as directed but serve it diluted with more water or sparkling water to taste.
- → Can I turn this into an alcoholic beverage?
Absolutely! This basil lemonade makes an excellent mixer. Add vodka for a basil lemonade cocktail, gin for a herbal twist, or white rum for a mojito-inspired drink. About 1.5 oz of spirits per glass works well, or add to the pitcher following a 4:1 ratio of lemonade to alcohol.
- → How long does the basil-infused simple syrup last?
The basil simple syrup can be stored separately in an airtight container in the refrigerator for up to 2 weeks. This allows you to make smaller batches of lemonade as needed or use the syrup in other beverages and cocktails.
- → Can I use a sweetener other than white sugar?
Yes, you can substitute honey (use 3/4 cup as it's sweeter), agave nectar, or even coconut sugar. Each alternative will slightly alter the flavor profile. For sugar-free options, stevia or monk fruit sweetener can work, but you'll need to adjust quantities according to their sweetness level.
