Healthy Shamrock Shake (Vegan, Paleo)

It’s that time of year again, when the popular “Shamrock Shake” is available for a limited time, to celebrate St. Patrick’s Day.


But, did you know there are 54 ingredients in this particular shake from McDonald’s? These ingredients include artificial dyes and preservatives, not to mention high fructose corn syrup and carrageenan– all of which aren’t exactly doing our body any favors.

Instead, try making this healthier minty green milkshake at home. It gets its green hue naturally, thanks to a handful of fresh spinach (which you can’t taste!) and a touch of avocado, which also makes it ultra-creamy. Paired with naturally sweet and fiber-rich dates, plus a splash of pure peppermint extract, this shake tastes as wonderful as it will make you feel.

Even better, you can prepare it faster than visiting a drive-thru window.

Healthy Shamrock Shake (Vegan, Paleo)
Serves 1


1 cup almond milk, or water
1/4 avocado, pitted
1 handful fresh baby spinach
1/4 teaspoon pure peppermint extract
5-6 soft Medjool dates, pitted
handful of ice


Combine all of the ingredients in a high-speed blender, and blend until smooth and creamy. Adjust sweetness to taste, if necessary, and serve immediately.

Healthy Shamrock Shake (Vegan, Paleo)
Prep time: 
Total time: 
Serves: 1
A healthy, minty green shake, perfect for celebrating St. Patrick's Day!
  • 1 cup almond milk, or water
  • ¼ avocado, pitted
  • 1 handful fresh baby spinach
  • ¼ teaspoon pure peppermint extract
  • 5-6 soft Medjool dates, pitted handful of ice
  1. Combine all of the ingredients in a high-speed blender, and blend until smooth and creamy. Adjust sweetness to taste, if necessary, and serve immediately.


  • If your blender doesn’t handle dates well, try using 1 to 2 tablespoons of pure maple syrup instead.
  • If you can’t have avocado, leave it out and add a spoonful of nut butter for extra creaminess.
  • Since the flavor of peppermint extracts vary, you may want to start off with just 1/8 teaspoon, and add more to taste. They can be very potent!
  • You can make this shake sugar-free by omitting the dates and using stevia, to taste.

Reader Feedback: Are you a fan of minty milkshakes? Mint chocolate ice cream used to be my very favorite, so this shake is right up my alley. (Especially with a few dark chocolate chips blended in!)

    I noticed some of your recipes have dates in it, that I can’t have. Is Maple Syrup always a good replacement??

  2. Karah

    I was thinking about making one with mint-flavoured chlorophyll (which would also be green), instead of the peppermint extract.

    Mint chocolate chip ice cream was my favorite as well but, I don’t eat ice cream any more. I can’t wait to try this!! I have everything except the avocado & will have to wait for one to ripen! Thanks for all your great recipes. My husband & I love your carrot ginger dressing – we have it probably 4 out of 7 days a week! I made your raspberry chocolate muffins last week too.

    I thought carrageenan was just seaweed. I quickly read a wiki about it and it seems it’s a seaweed derivative and caused tumors in some trials. I’ll stick to chia or flax for thickening…
    Thanks for the recipe!

    Wow dont think we get that drink over here but look delicious. I have been making my own almond milk and cant get over how easy it is! need to get me some peppermint oil too – so good for my tummy!

    I make a shamrock shake often. Mine’s a bit different, but the secret ingredient I use is a frozen banana or two! It’s soo yummy that way and gives it the “traditional” icecreamy taste.

  10. Dawn

    This is DELICIOUS! Just made it for myself and can’t wait to share with my picky Kiddos! Love all your recipes, Thanks for all your inventive cooking and sharing. Good luck with your cookbook.

    As a former fan of mint chocolate-chip ice cream too, I’m definitely a fan of minty smoothies. I decided on Saturday that I would make a minty green smoothie like this, without the avocado and dates, but with almond butter. It’s so great that I’m sipping it all week long.

  12. Kara

    We are allergic to avocado at my house. Banana sounds like a good substitute for the creamy texture but for those who have tried it, does it taste like banana? Banana/mint doesn’t sound like a good combination to me.

    I tried this recipe as written, and it was outstanding. I have family coming into town this week who live in a different part of the country and are struggling with health issues related to sugar addiction and poor nutrition. This recipe comes to me at an absolutely perfect time, and I can’t wait to share it with them! Thanks again.

  14. Mary

    I will be trying out this recipe soon!
    I LOOOVE the adorable glass you are serving it in? Did you get it any place special?

  15. Lynn

    Made a double batch for dessert for my husband, two boys and me last night – it was FANTASTIC! I didn’t have the dates, but the maple syrup provided the perfect amount of sweetness without tasting maple-y (threw in some dark chocolate chips too). Everyone loved it. Just discovered your website as I was looking for wheat free recipes. Really looking forward to trying more of them. Thank you!

    You have outdone even yourself! My children just had spinach and avocado for dessert!!! And I am licking the blender. It is delicious and the only change I would recommend is to double the recipe! Happy St. Paddy’s Day, and as they say in Ireland, Thank You!!

  22. Kim

    This was DELICIOUS!! My daughter was craving the McDonald’s shamrock shake so I made this instead. She liked it better than McDonalds. We will be making this again… OFTEN!! THANK YOU for your wonderful recipes.

  23. SuperMario

    We made them 3-4 nights in a row. My 6 year old girl kept begging for them. She even saw all the ingredients I put in the blender. One of the times I put in extra ice and extra avocado, added a few dark chocolate chips and we had peppermint bonbon ice-cream 🙂

  24. J

    This is so yummy! The avocado gives it that creaminess you just miss from other smoothies…..great replacement from ice cream and I still get my shamrock fix. Thanks!

  25. Molly

    This is an AMAZING recipe!! I had just feeling nostalgic for the mint chocolate chip shakes at Baskin Robbins, and this is nearly identical in flavor! I made a half recipe, and I didn’t have any spinach so instead I substituted about 5 leaves of endive that I had around the house. SO DELISH! Thank you thank you!!!

    Hi there, Love the green smoothie! I just found a web site about certain vegetables to not eat them raw … like spinach as they are a Cruciferous vegetable and should not be eaten raw.

    I wanted to share and was wondering your opinion on this as you studied it and it is a profession of yours. I wanted to go to the professional rather then listening to a web site post.
    Thank you! : ) Eva from Canada.

    I have used avocado in a smoothie a couple of times – I normally use banana. With dates and peppermint extract, this sounds delicious! I love that it’s vegan and gluten free.

    It was amazing! My kids loved it too! Your website is so wonderful, I use it almost daily. Do you know of any nut, sugar and dairy free chocolate chips? I would like to add the chocolate next time; we use Enjoy Life but it has cane syrup?

    This is one of my all time favorite green smoothies! I had run out of peppermint extract and kept forgetting to buy it at the store…So glad I remembered to pick some up at Whole Foods this week and this refreshing yummylicious shake is back in rotation…I love this with Kale and coconut milk as well and if your dates have gotten a little hard, they are easy to soften up by soaking them in the “milk” of your choice the night before you are going to use. Thanks Meagan for all your amazing creations!

  35. Stefani

    Thank you so much for sharing this recipe. My kids always beg me to get shakes on St. Patrick’s Day, and I just can’t do it knowing what is tin them. These were a big hit not only with my family, but all the neighborhood kids. I ending up making three blenders full.

  36. Jen

    Of course Megan has just what I am craving and so delicious! I added some Enjoy Life chocolate chips to this and it hit the spot. Yum!

  37. Brianna

    Thanks for the avocado substitution suggestion. I’m going to try to make this tonight. Avos are a migraine trigger for me, so I avoid them at all costs.
