I think you knew this was coming. After the lineup of St. Patrick’s Day recipes I’ve shared in the last two weeks, it would have felt odd not to post on the day itself. I have one last lucky recipe for you lads and lasses, a Green Whiskey Smash.

Irish Whiskey Smash — St. Patrick’s Day twist on the classic whiskey smash cocktail, which calls for lemons, whiskey, simple syrup, mint. This festive version uses Irish whiskey and lime to make it a green drink! Recipe at wellplated.com | @wellplated

A whiskey smash is a classic cocktail with just four ingredients: whiskey, mint, lemon, and simple syrup or sugar. Five if you count the ice. You don’t need any fancy equipment to make it, and you’ll feel like quite the accomplished home bartender when you shake up a round for your guests.

What is a Whiskey Smash Cocktail?

If you aren’t a fan of whiskey, a whiskey smash is an easy gateway. The brightness of the lemon and crispness of the mint make it more refreshing than boozy, so it’s dangerously easy to drink. Tip: sip slowly and let the crushed ice melt a bit.

If you are a fan of whiskey, you may have noticed this cocktail’s similarity to a mint julep. They’re close cousins, with the major difference being the addition of citrus to the whiskey smash. If I had to choose one of the two to drink for life, I’d pick the whiskey smash.

Unless it’s St. Patrick’s Day, in which case, I’m picking the Green Whiskey Smash.

This Green Whiskey Smash is a classic whiskey smash cocktail recipe with a few festive tweaks. I replaced the lemon with lime to make it green, swapped the simple syrup for agave because I rarely have prepared simple syrup on hand, and used Irish whiskey, as no other would have felt appropriate on St. Patrick’s Day.

If you are trying a whiskey smash for the very first time, I’d recommend starting with the classic recipe using lemon and regular whiskey (or bourbon) instead of the lime and Irish whiskey. Arguably lemon is a better pairing for whiskey than lime, so I’d want the original recipe to be your first impression of this most excellent drink.

If, however, you are already well acquainted with the whiskey smash and want to try a fun holiday twist with this Green Whiskey Smash, by all means, CHEERS!

Irish Whiskey Smash. A St. Patrick’s Day twist on a classic whiskey smash cocktail recipe that uses Irish whiskey and lime to make it green!

Prep: 1 min
Cook: 0 mins
Total: 2 mins

Servings: 1 drink


  • 8 fresh mint leaves plus additional for garnish
  • 1/4 lime (for a green version) or lemon (for a classic version) cut in half
  • 2 teaspoons light agave nectar or simple syrup
  • 2 ounces Irish whiskey (for the green version); use bourbon or whiskey of choice for the classic version or bourbon or other whiskey of choice
  • Crushed ice


  • Place the mint leaves, lime wedges, and agave in the bottom of a cocktail shaker or mason jar. With a muddler or the handle of a wooden spoon, mash 4 to 5 times, just enough to release juices and oils. Add the whiskey and top with a small handful of crushed ice.
  • Cover and shake vigorously for 30 seconds to combine. Transfer to an old-fashioned or similar glass. Pile more crushed ice on top. Garnish with additional mint sprigs. Enjoy immediately.


  • If you'd like to try this as a classic whiskey smash: For each drink, use 1/2 lemon instead of the 1/4 lime and 2 ounces regular whiskey or bourbon (I like Bulleit) in place of Irish whiskey. Or you can do lemon and Irish whiskey, which would be a delicious happy medium.

  1. Now I’m not Irish at all, but all I have to say to this is YES! :D It’s 5 o’clock somewhere, right?? ;)

  2. I just got some fresh mint sitting in my window cill! Time to put it to use…

    Also, these pictures look awesome.

  3. This is such a fun drink! The mint, lime, and agave make me think tequila, but I love the use of whiskey here-what a festive twist :)

  4. We’re Old Fashioned drinkers so this sounds right up our alley – will try this definitely. Off topic: I had a meeting this morning and I left some of your Banana Pancakes for him. I had frozen some of those leftover when we had them the first time…really good then. He put them in the toaster oven and treated them like toast timewise. Said they were even better than fresh – go figure. Good weekend wishes.

    1. I hope you enjoy it, Chris! And thanks for the tip about the banana pancakes in the toaster oven! :) Wishing you a nice weekend as well.

  5. Kate, I am so glad you mentioned that about Maker’s Mark! That slipped my mind. I removed it. Also, that tour sounds like it would be amazing!

  6. Sounds interesting Erin. I love mojitos and this sounds like a mojito with whiskey instead of rum. Will give it a try. Happy St. Paddy’s! :)

  7. That is a beautiful way to celebrate saint patties day (: I think I could have a few of those ;)

  8. Trevor LOVES whiskey, so I think he’d be all about this cocktail! Hope you had fun celebrating!!!

  9. This looks amazing — I was just about to make it when I realized I was out of Jameson!  Oh, well, this gives me an excuse to grab another bottle!
