Green Margarita

I can’t believe how fast March is flying by! This green margarita recipe would have been perfect for National Margarita Day which is celebrated on February 22nd here in the United States. It’s even better as a St Patrick’s day margarita with it’s green color. If you are looking for something besides green beer, this recipe is for you.

Now, when I say the opposite direction I mean that it stopped being 88 degrees and dropped down into the low 50s. Some of y’all will be celebrating St Pattys Day in down parkas and snow boots. I get it. I’m spoiled, I know. I was just enjoying my daffodils and such not ready to be pulled back into winter weather. Hope you have some nice weather to celebrate with this low carb margarita.

St Patrick’s Day Margarita

St Patrick’s Day is actually a great holiday for low carb people. Think about it corned beef and alcohol are both easy on the carb limit. I had made an Irish Margarita before and I thought that surely I could come up with something just as green with great taste, but low carb.

Most margarita recipes have things like simple syrup, fruit juice, triple sec, and or agave nectar which makes it taste great, but really ups the carbs. This recipe has all the flavor, but none of the sugar. They also have salt on the rim which you can add. For me, I’m trying to watch my salt intake but please add it if you like it. Using a lime, wipe the rim of your margarita glass. Then put some salt on a shallow plate or bowl. Dip the rim into the salt. The salt should stick to the rim. Do this before you pour the margartia mix from your cocktail shaker.

Carbs in a Margarita?

If you haven’t jumped on the water enhancer wagon I really encourage you to do so. Water enhancers come in all kinds of colors and all kinds of flavors. Best of all most of them are 0 carbs, just be sure to read the nutrition info just in case. You can usually substitute any fruit juice ingredient called for in a cocktail with club soda and the correct flavor of water enhancer.

A regular margarita can have almost 10 net carbs in 1 cup. Along with the tequila, it’s not something that’ll fit in a low carb lifestyle. This St Patricks day green margartia recipe has 0 net carbs !

Hope you enjoy this low carb green margarita. Please have a great time on St Patrick’s day! As always, drink responsibly please?

MiO makes a very green water enhancer that’s perfect for this cocktail recipe!

  1. 5 stars
    Can i drink one or two of these during induction? If not, at which phase of my LC journey?

    Thanks so much – these recipes are a lifeSTYLE save and easy-peasy for the busy working woman/mum.

    1. Atkins suggests no booze during induction and only occasionally during ongoing-weight loss. Even though there are low to no carbs your body stops burning fat and begins to burn off the alcohol so it interrupts the process and it can take awhile to get going again.
