Limoncello Old Fashioned Cocktail Recipe

Isn’t it wild how a classic cocktail can feel brand new with just one small change? The Limoncello Old Fashioned mixes the rich, mellow taste of whiskey with limoncello’s zesty citrus, making a drink that’s both cozy and unexpectedly bright.

This recipe walks you through a cocktail that brings a splash of Italian sunshine to a timeless favorite.

Swapping out simple syrup for limoncello really surprised me the first time I tried it. The limoncello adds just enough sweetness without drowning out the whiskey.

You can tweak the recipe to your liking, or get a little adventurous—try arancello, peach preserves, or even muddle in some basil or lavender. Each twist brings something different, so it never gets boring.

If you’re into whiskey sours or limoncello spritzes, this cocktail lands somewhere in the middle. It’s smooth, citrusy, and goes down easy.

You don’t need fancy gear or rare ingredients either, which is always a plus.

Limoncello Old Fashioned Cocktail Recipe

I love how this drink brings together the bright flavor of Italian lemon liqueur and the smooth depth of bourbon. The combo of citrus and oak creates a cocktail that’s both refreshing and rich.

You can easily make it at home with just a few tools and simple ingredients.

Equipment

• Mixing glass or cocktail shaker for stirring or shaking the drink.
• Bar spoon to gently mix the ingredients.
• Jigger to measure the bourbon, limoncello, and syrup accurately.
• Strainer to pour the drink cleanly into the glass.
• Old Fashioned glass (rocks glass) for serving.
• Muddler if you want to press fresh mint or rosemary for aroma.
• Peeler or zester for a lemon twist garnish.
• Ice cubes or a big ice sphere to keep things cold without watering it down.

Having the right tools makes it way easier to get the flavor, temperature, and texture just right.

Ingredients

• 2 oz bourbon or rye whiskey
• 1 oz limoncello or homemade limoncello
• ¼ oz simple syrup or honey syrup
• 2 dashes black lemon bitters or Orleans bitters
• 1 small lemon peel or fresh lemon twist for garnish
• Optional: fresh mint or fresh rosemary sprig

Limoncello brings a lemony sweetness that pairs beautifully with bourbon’s caramel notes. I lean toward a good Italian limoncello, but homemade totally works.

A couple dashes of bitters keep things balanced, and fresh herbs or lemon peel give it a crisp finish.

Instructions

• Fill your mixing glass halfway with ice.
• Pour in the bourbon, limoncello, and simple syrup.
• Stir gently for about 20 seconds, just until it’s chilled.
• Add the bitters and give it another quick stir.
• Strain the drink into an Old Fashioned glass over fresh ice.
• Express the lemon peel over the glass to release the oils, then drop it in.
• Toss in a sprig of mint or rosemary if you’re feeling fancy.

If you want a lighter version, shake everything with ice and strain it into a chilled glass with no ice. That really lets the lemon flavor shine.

Notes

I usually reach for bourbon for its mellow warmth, but rye gives the drink a nice spicy kick. If you want something lighter, try gin or vodka—it’s a whole different vibe but still tasty.

Chill your limoncello in the freezer so it stays syrupy and cold—trust me, it makes a difference.

For a softer sweetness, swap simple syrup for honey syrup. You don’t need fresh lemon juice; the limoncello brings enough citrus on its own.

Fresh herbs like mint or rosemary add aroma without taking over. Sometimes I rub a rosemary sprig along the rim for a subtle herbal scent that plays well with the lemon.

Tasting Notes

I take the first sip, and right away, a bright lemon aroma hits me—fresh, clean, and honestly, a little surprising. The limoncello’s sweetness steps in and smooths out the gentle bite from the bourbon.

It’s got that warmth, but nothing harsh; it just kind of lingers quietly. As I keep sipping, the citrus flavor really comes forward, almost like I just zested a lemon right into the glass.

The sugar and bitters mellow everything out, so it never gets too sharp. I appreciate how the drink keeps things light, never crossing into that heavy, syrupy territory.

By the end, a soft oak note from the bourbon drifts in and mingles with the lemon. I can’t help but think of a classic Old Fashioned, but this one’s got a sunnier, more playful edge.

The texture? Silky, never sticky. I like to take my time with this one, usually after dinner, just letting it work as a digestivo.

That gentle citrus and mild sweetness settle my palate without ever feeling too much. It’s got this refreshing, comforting vibe—especially when I drop in one big ice cube and just let it chill.
