Reasons To Love This Cocktail

Love a good gin and tonic? So do I! But I also love to replace the gin with limoncello sometimes. The sweet lemon flavor of the limoncello pairs perfectly with the slight bitterness of the tonic water. Limoncello and tonic is a summer favorite!

  • Only 2 ingredients (plus ice): Nothing beats simple on hot and lazy summer days!
  • Easy to make: No fancy equipment needed! Just pour into a glass filled with ice and add a garnish if you like. Super easy!
  • Refreshing: Perfect for summer sipping! Another refreshing limoncello cocktail to try is this Limoncello Spritz.

Tip: Chill the limoncello and tonic water ahead of time. This cocktail tastes best when the ingredients have been chilled in advance.

Make A Gin Limoncello And Tonic

Don’t want to skip the gin? You could also make a limoncello gin tonic. Simply add some limoncello to your G&T for a pop of bright lemon flavor.

Feel free to play with the ratios but I like: 1 ounce gin + 1 ounce limoncello + 4 to 6 ounces tonic water.


  • Use a different herb garnish: Instead of rosemary, you could also use mint, basil or thyme.
  • Add lemon slices: Garnishing with fresh lemon slices is also a nice addition.
  • Adjust proportions: It’s your drink so feel free to adjust the ratios to suit your tastes!


What is limoncello?

Limoncello is a sweet Italian lemon liqueur originating from Southern Italy. It is made from lemon zest, sugar and a neutral alcohol like grain alcohol or vodka. Limoncello is the second most popular Italian liqueur (after Campari). It is traditionally served chilled as an after-dinner drink (digestivo) but is also a popular ingredient in cocktails for a pop of lemon flavor without the sourness.

What does limoncello taste like?

It kind of reminds me of sweet lemon hard candies. It tastes sweet with an intense lemon flavor.

Where can I find limoncello?

You can find limoncello at the liquor store or make it at home. I prefer to purchase it since I know that the Italian lemons used are different from those that I will find at my local grocery store.

    wow i can’t believe it is only 2 ingredients and how refreshing it was. We have a heatwave all week and i’ve been living on this drink!!

      It’s been so hot here as well! Easy refreshing cocktails like this are perfect for heatwaves!

  2. Cindy Mom the Lunch Lady says:

    My Italian MIL will love this cocktail. She always has Limencello on hand!

    1. Vanessa | Maple + Mango says:

      Hope she enjoys it!

  3. Sean says:

    Delightfully summery simplicity! I do love a good G&T, and I think this is a perfect variation on the idea. Love that you took the time to emphasize a good tonic too – the cheapo stuff is pretty underwhelming, and given the prominence of tonic here, you’re definitely right about wanting to pick a good one! I haven’t tried the brand you recommended, so I’m going to have to look out for it. Cheers!

    1. Vanessa | Maple + Mango says:

      A good tonic is definitely key in this simple cocktail. Enjoy and cheers to you as well!

  4. Colleen says:

      I’m so glad you and your friends enjoyed them! Weekend happy hour on the patio sounds fantastic!

  5. Bernice says:

    Oh my gosh! You made me so thirsty I had to make myself drink. I try to enjoy my cocktails on the weekend but after the day I had, it was much needed! So glad I keep a local limoncello in the liquor cabinet.

    1. Vanessa | Maple + Mango says:

      Haha – glad you had that limoncello on hand! I usually have a bottle in the freezer and tonic water on hand which makes this a super easy cocktail to put together any time mood strikes.

  6. Beth says:
