Healthy Shamrock Shake

This post may contain affiliate links. Please read my disclosure and privacy policy.

This healthy Shamrock Shake is bright green with a sweet and minty flavor. This mint smoothie is naturally-sweetened with fruit (not banana!) and gets its vibrant hue from spinach, instead of food dye.

What’s really in a Shamrock Shake?

Did you know there are 54 ingredients in the shamrock shake from McDonald’s? These ingredients include artificial dyes and preservatives, along with high fructose corn syrup, and a medium-sized drink will run you 660 calories. (Which is more than a Big Mac!)

What makes this version healthier?

Luckily, it’s pretty easy to make a healthy Shamrock Shake at home. This version gets its green hue naturally, thanks to a handful of fresh spinach (which you can’t taste!) and a touch of avocado, which 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.

The dates add a nice, neutral flavor to this drink, unlike a smoothie that is sweetened with banana, but if you don’t have a blender that can break them down, try using a splash of pure maple syrup for sweetness instead. (In that case, you could add some frozen cauliflower to thicken up the drink instead– you can’t taste that in smoothies, either!)

How to Make It

To make this healthy shake thick & frosty like the original drive-through version, I recommend blending the first 5 ingredients together first, until the dates are totally broken down. Then add some ice and blend again until you achieve an ice-cream-like texture.

What I love about making smoothies at home like this one is that YOU are in control of the final flavor. If you want it sweeter, add another date! Or more peppermint flavor? Add an extra drop of the peppermint oil. Feel free to keep adjusting until it’s perfect for you.

Recipe Notes:

  • 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. Homemade almond butter will have the most mild flavor.
  • 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!)

Oh yeah! This looks great. I think I’ll switch the dates for 1/2 a banana. Yum.


    That’s what I do. It’s delicious!


What if you are allergic to tree nuts? Could you use soy milk?


    I’m guessing that you can use any type of milk


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


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.


    She has a recipe for mint-chocolate chip ice cream, that doesn’t have cream or milk in it.


What is the difference between carrageenan and Irish Moss?

Danica @ It's Progression

I’ve never had a shamrock shake or even wanted to try one, but your version sounds delicious!!


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.


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.

Ceara @ Ceara's Kitchen

I love avocados in smoothies and this one looks to refreshingly creamy and good! Can’t wait to try!!


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.


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.


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?


Looks like a very tasty alternative – I didn’t realise there were so many ingredients in the Mcdonalds one –


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!

Jess @ Crunchy Hot Mama

Yum! I plan to make this today but leave out the peppermint since I’m still nursing. I’ll just have to add it to my list of drinks after bebe is done 😉


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!!


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.


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 🙂


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!


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!!!


This is so delicious! My 16 month old son is obsessed with it too 🙂 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.

melissa gibson

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?

Dawn Hadley

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!


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.

    Megan Gilmore

    Yay! I’m so glad to hear that!

Erin L

This was SO good. My daughter loved it. Especially with dark chocolate bits in it 😉
Thank you!!


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!


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.


Can I use fresh mint instead of the peppermint extract?


I love this milkshake! Not too minty or too sweet, and the spinach is just enough to make it green. You can’t even taste it! The avocado makes it so smooth like ice cream does to an actual milkshake. I make it for my little brother at least once a week. Thank you Mrs Gilmore!!💖😁😉


This is one of my favorite smoothies of yours. I do think it tastes better than McDonald’s!

Darcy Rybczyk

Has anyone made it without Spinach? I can’t have it wondering if it would taste good without?

    Megan Gilmore

    Yes! The spinach doesn’t really affect the flavor either way, it’s just for the green color. 🙂


And I only used 3 dates to cut sugar. Some would need the extra sweetness, I imagine.
Thank you ! I can always count on you to have wonderful recipes!

Trish nordstrom

I made this today to make sure I liked it before bringing it to a St Patrick’s day breakfast this weekend. It was delicious! I feel other recipes I’ve tried are always too creamy or too bland, but this is perfect! (1/4 avocado is exactly the right amount of creaminess) So easy and my kiddos drank it up, too! Another winner from Detoxinista!


Exactly the smoothie I needed this morning – stressful day with work and everything else going on in the world! But a little bit of tradition and fun put a smile on my face. Deliciously sweet but healthy. The only change I made was to use beet greens because I just harvested my beets from the garden and have a lot of those greens. Worked perfect and it was still green. Thanks!


Excited to try this…finally something WITHOUT BANANAS! Thank you!


I’m not a fan of “flavorings” or extracts. I used a couple handfuls of fresh mint leaves instead. Yummy!
