If I were hosting in spring or summer, we’d be sipping these Olive Oil Basil Limoncello Sours in the sunshine. We’d have our cocktails in coupe glasses, a silver bowl of salty snacks nearby, and that early summer “why not another?” kind of mood. It’s bright, silky, and a little unexpected. And that’s exactly the point.
This cocktail is perfect for aperitivo hour: herbaceous from fresh basil, citrusy from both lemon juice and limoncello, and rich from a splash of olive oil and egg white. It’s a little savory, a little sweet, and honestly, one of the most elegant sours you’ll shake up this season.
Let’s Make Homemade Limoncello
How to Make an Olive Oil Basil Limoncello Sour
- First of all, you totally don’t have to make your own Limoncello. Store bought limoncello is delicious (but making it yourself is also really easy).
- Add gin, lemon juice, simple syrup, limoncello, basil leaves, egg white, and olive oil to a cocktail shaker and dry shake (no ice) for about 20 seconds to emulsify the egg white and olive oil.
- Add ice and shake again until well chilled and frothy.
- Double strain into two chilled coupe glasses.
- Serve with olives, nuts, and salty chips for a full aperitivo moment.
Limoncello Sour Ingredients
- Gin – A citrus-forward or herbaceous gin like Botanist, Monkey 47, or Hendrick’s works beautifully here.
- Limoncello – Brings bright, sweet lemon depth. Use homemade or store-bought.
- Basil – Muddled or shaken straight in; gives the drink its green, aromatic lift.
- Olive oil – Use a fruity, high-quality Extra Virgin Olive Oil for smooth texture and soft savoriness. I used the DAOU and omggg you NEED to get your hands on it!
- Egg white – Creates the signature foam and mouthfeel of a classic sour. Sub aquafaba for a vegan version.
- Lemon juice – If it’s not fresh… we don’t want it!
- Simple syrup – If you can boil water, you can easily make your own simple syrup!

Limoncello Sour Tips & Variations
- Use aquafaba – For a plant-based foam, sub egg white with 1 oz aquafaba.
- Make it non-alcoholic – Try a non-alcoholic gin and limoncello substitute with the same proportions.
- Infuse the syrup – A basil- or lemon-infused simple syrup can boost flavor even more.
- Pre-batch the base – Mix everything except the egg white and olive oil ahead of time for quick shaking when guests arrive.
When to Serve It
This is your go-to cocktail for sunny sophistication. Serve it at:
- Early evening aperitivo hour
- Alfresco dinner parties
- Brunches that lean savory
- Any time you want to impress with a “Wait… what’s in this?” drink
Pair it with olives, potato chips, salty nuts, and a breezy playlist.

I’m going to make this this weekend, but I have so much vodka so thinking to swap the gin?! Do you think it would still work well?
Yes absolutely! Vodka is the perfect neutral swap here!
