[Super Thick] Shamrock Smoothie

I don’t know what it is, but I can’t get enough peppermint lately. I think it started with the stash of Candy Cane Lane tea that I hoarded over the holidays (I still have some left!) and the love grew even stronger when NuNaturals sent me some of their Peppermint liquid stevia to try. I’ve been adding to tea, plain Greek yogurt, unsweetened almond milk… you name it! But, my favorite way to enjoy it has been in my recovery smoothie.


This is the time of year where I usually see ads for McDonald’s Shamrock Shake pop up all over the place. Strangely enough, I haven’t seen a single one! I’ve actually never tried one before, and I’m sure they taste delicious (really, it’s pretty hard to screw up a milkshake!). But, Greg has had a real Shamrock Shake before and actually said that my version tastes even better… and I don’t think he was just being nice.

A 16 oz. McDonald’s Shamrock Shake clocks in at 680 calories and has 20g of fat (12 g saturated!). My version comes in just a little bit lower at 130 calories and 1g of fat*. :)

*This will vary depending on the protein powder you use. I used Wegman’s Natural Vanilla Whey Protein.

I posted a Shamrock-ish Shake recipe last year that was a little more decadent, but for this version, I simply tweaked the recipe for my recovery smoothie. Using frozen spinach over fresh adds thickness to the smoothie, along with the frozen banana xanthan gum. I’ve been alternating between using vanilla and chocolate protein powder- both are equally delicious! However, if you really want to achieve a bright shade of green, I’d go with vanilla.

The ingredients:


All set to go!



Super Thick Shamrock Smoothie

1 scoop vanilla protein powder

2 cups of ice

1/2 of a small frozen banana

1/2 c frozen spinach

1/4 c unsweetened almond milk

1/2 c water

1/8 tsp xanthan gum

6 (ish) drops NuNaturals peppermint liquid stevia – can sub with peppermint extract

1/2 tsp vanilla extract

Add all ingredients into a high speed blender. Blend for about 1 minute, or until mixture reaches desired consistency.

To me, that looks like this:


When your smoothie is this thick, it’s best to eat it with a spoon. :)

I’m pretty sure I’ll be continuing to enjoy these long after St. Patrick’s day!



Are you a peppermint fan? What’s your favorite flavor combination (using peppermint)?



  1. This looks SO yummy and I love the peppermint stevia!!!! Kinda excited to try this!!

  2. That looks so delicious!! I must give it a try :)

  3. Guess who has all of those ingredients in her kitchen right now?

    And guess who loves the color green?

    And guess who remembers thinking Shamrock Shakes were the best thing ever when she was a younger person? [Aside from the ORANGE shakes that happened in the later spring, of course.]

  4. I’ve never had a shamrock shake before.

  5. This sounds so fun, I know people are really into the McDonalds shamrock shakes. I’m not a huge fan of peppermint flavor but love banana and spinach in smoothies. Maybe with almond or coconut extract!

    • Nicole- I wasn’t a peppermint fan until recently. If you give it a try it MIGHT change your mind… (when you combine it with vanilla, magical things happen!)

  6. I’ll definitely be trying this. Funny thing is, I’ve never been a fan of McDonald’s version . . . the flavor just seems off to me. But in general, I love peppermint–and this shake looks insanely decadent!

  7. That looks delicious…but I have to ask…do you taste the banana at all? Cuz homey don’t mess around with bananas, and kind of wishes the fruit would go extinct. :P

    • You don’t taste it at all- and really, you don’t HAVE to use it. It just makes the consistency creamier. I wouldn’t leave it out, personally!
      And I don’t think we can be friends anymore if you’re going to talk about my friend Bananas that way.

  8. This looks great! Where do I find xanthan gum and what exactly is it?

    • Hey Pam! Xanthan gum is a natural thickener that is used a lot in gluten-free baking. You can find it in the natural foods section in pretty much any regular grocery store (in Wegmans it’s with the gluten-free stuff). A whole bag of it is pricey- but will last you FOREVER because you only need a teeny tiny bit. I buy it in bulk at Common Market- it’s with the bulk spices in the healthy & beauty section.

  9. I use peppermint essential oil in my smoothies–and yes! It makes it taste like a thin mint cookie. Or melted peppermint ice cream. Mmmmmmm! Yours looks fab too!!

  10. I love shamrock shakes. I really want to try this!

  11. That looks amaaaaazing

  12. Now that I think about it, I haven’t seen a McDonald’s mint milkshake ad this year either…

    BTW, because I enjoy reading your blog, I just nominated you for a Liebster award! The “rules” are on my post today.

  13. I haven’t had a shamrock shake yet this year. I’d love to make my own. This looks GREAT!

  14. Diane @ life of Di. says:

    This looks so delicious! I have never tried a Shamrock Shake but I would really love to but without the ridiculous amount of calories. Ugh. I still don’t understand how some products jam pack so many calories into something that seems little or not as bad-you know?

  15. I’m seriously drooling all over myself!….and pining over your Vitamix “clover” Ahhh, one day, Vitamix, you WILL be mine! ;)

    You know, I haven’t seen any of the Mickey D’s shakes either…wonder if they stopped making them? Perhaps caused a few too many heart attacks? SIX HUNDRED CALORIES?!!? Holy bejesus!

    I was never a huge fan of peppermint until this past year when I realized my undying love for peppermint and chocolate together! Thank YOU NuNaturals…it’s all YOUR fault! Lol

  16. I love peppermint!! I need to try the peppermint stevia. I recently got a Costco membership and I’ve been eyeing a Vitamix ever since!
