Keto Long Island Iced Tea Cocktail

Keto Long Island Iced Tea Cocktail is the perfect summer thirst quencher, with a lot of kick! We make ours with low-carb ingredients. It is also a great summer party drink – it looks great in a pitcher. Everyone can help themselves. It has been described as a “mess of a drink” since it combines a variety of hard alcohols. However, it is a classic since it has a really cool name and tastes great!

There is no iced tea in a Long Island Iced Tea. It is simply the same color as iced tea, since the cola adds the amber hue. We actually once had a good laugh with friends one summer when we mixed up a batch and filled empty iced tea bottles. The ladies were in on the joke and each asked for an iced tea while the men had a cold beer. It was a lot of fun when the guys figured it out. I guess that was a bit of Tasty Low Carb humor.


Most say the Long Island Iced Tea was indeed invented on Long Island in the 1970s. It uses a mixture of tequila, gin, vodka, and white rum. Most recipes call for Triple Sec and sweet-n-sour mix. Lots of ice and topped with a cola for color completes the recipe. To make this one a Keto Long Island Iced Tea Cocktail we substitute a dash of orange extract for the Triple sec. We also use our Low Carb Margarita Mix as a substitute for the sweet-n-sour mix. It is a blend of lemon and lime and works well. The orange flavor and lemon-lime do blend well with the diet cola.

A lot of ice and a bit of diet cola (Coke, Pepsi, or Dr. Pepper) will provide the right color blend and the proper dilution for a tasty drink. Some folks like a similar drink called a “Grateful Dead.” It has the same ingredients except it calls for Chambord rather than Triple Sec. We will have to search for a raspberry substitute for that one.

Preparation Tips

Preparation for this one is easy. Simply add a cup of ice cubes to a good copper cocktail shaker with all of the ingredients except for the diet cola, and shake. We used mason jar glasses for our presentation, but most will call for a tall glass. Either way, top it with about 2 1/2 ounces of diet cola. The mason jars were a bit larger so we added more diet cola and this produced the darker color. However, the less you add, the greater the kick. You be the judge!

We garnish our Keto Long island Iced Tea Cocktail with a slice of lemon. Since, a lot of folks serve iced tea with a dash of lemon this makes a lot of sense. It looks great and tastes even better. On a hot summer day this is a real thirst quencher, but do tread lightly. To cut down on the kick a bit, you will notice we only use a small amount of each alcohol.
