My Top Secret Diet Weapon


Green Monster Spinach Smoothie is packed with good-for-you ingredients — it’s my favorite way to start the day! 

Continuing the theme of my post-vacation shape up, I went home and drank my veggies for lunch in the form of a Green Monster Spinach Smoothie!

Green Monster Spinach Smoothies are one of my top secret diet weapons, because although they’re packed with baby spinach, which make my skin, hair, nails, and overall self feel totally great, they do not taste healthy at all. I repeat, they do not taste healthy at all.


  • Spinach is fat free, cholesterol free, low in calories, and very low in sodium
  • Spinach is an excellent source of vitamin A, C, K, iron, fiber, folate, and lutein
  • Leutin is an antioxidant that promotes good eye health, and may help prevent cancer of the liver, ovaries, colon and prostate, and even dementia.
  • Dole lab tests found spinach juice has twice the chlorophyl, eight times the calcium, six times the magnesium, 10 times the potassium, 15 times the vitamin C and 43 times the vitamin A of wheatgrass juice!

Are you convinced yet? Well channel your inner Popeye and get to blending already!

First add 1 sliced frozen banana, and 1 Tablespoon peanut butter in a blender. Tip: PEEL and SLICE your bananas before you freeze them, or you’ll be sorry!

Next add bulking agents for staying power, like protein-packed vanilla Greek yogurt, and creamy unsweetened vanilla almond milk. You could use any kind of milk you want – cow’s, rice, soy, etc.

PS I started calling cow’s milk, well, cow’s milk, after I stopped drinking it last year in favor of Unsweetened Vanilla Almond Breeze, and it freaks. Ben. out. So hysterical.

Fill the blender the rest of the way up with baby spinach. I think I fit about 4 cups in there today!

Start the blender on “high blend” until everything’s mixed up, then switch it over to “liquify” to get the Green Monster velvety smooth.

Pure green gold!

  1. I’m big on banana + spinach + BERRIES, the seedier the better (raspberries, blackberries). Sometimes I get gutsy and even replace the spinach with kale leaves. >:) And I love adding in superfoods and supplements like flax, chia, maca powder, etc.!

    • CherubMamma 01.04.2012

      Adding chia is the best. I love the gel!

  2. Love green monsters! :)

  3. Abby 01.04.2012

    My favorite combo is vanilla protein powder + peanut butter + spinach + cow’s milk. I like to make this smoothie for an after-workout replenishing snack. I LOVE how the spinach doesn’t affect the flavor of the smoothie but only gives the smoothie a vibrant green color & TONS of nutrients! I agree; I almost feel guilty drinking something that tastes like a delicious ice cream shake!

  4. Amber 01.04.2012

    Ohhh! I just got a magic bullet so I’m super excited to try this out!

  5. Brenna @ Happ. B 01.04.2012

    Wow! Look at those stats. I’ll have to try this smoothie. I’ve made one with kale, pear, banana, and orange. I love sneaking in those greens :)

  6. Brenda 01.04.2012

    Spinach, banana, berries, greek yogurt! I also like to juice greens and veggies, yummy! My hubby just cant get past the green color, I think its pretty!

    • Iowa Girl Eats 01.04.2012

      I finally got Ben to try one last year, and he totally admitted it was awesome. HA!

  7. Manissa 01.04.2012

    Mmm green monsters! They always remind me of Starbucks’ green tea frappuccino! I sometimes use kale instead, and I like to add in frozen berries.

  8. erica 01.04.2012

    i used to make them all the time! i think it’s about time i start up again!!! :)

  9. This is exactly the way I make my green monsters! I leave the yogurt out if I just want more of a snack than a meal, and I usually add some protein powder. They are soooo yummy!

  10. Donna 01.04.2012

    Looks great! Have you ever tried making one in the morning and leaving it in the fridge til lunch? I would love to bring green monsters to work for lunch, but I’m worried it wouldn’t taste too fresh by lunch time.

    • Angela 01.04.2012

      You can freeze it and then let it unthaw an hour or so before you want to drink it! I’ve brought them to workouts and left them in my car to have as a post-workout drink!

    • Iowa Girl Eats 01.04.2012

      I’ve frozen mine too, and it works just great!

  11. I had one of those today, and every other day for that matter. I LOVE green smoothies!

  12. Stephanie 01.04.2012

    I make smoothies everyday for my man and I, will definitely have to make this!!!!!!! Thanks

  13. I always forget about the mighty green smoothie! I have to go to Trader Joe’s tomorrow anyway, so I’ll add spinach to my list of things to get :)

  14. Love, love, love!!!!! I hope you’re starting to feel refreshed.

  15. Caitlin Svec 01.04.2012

    Would this work in a magic bullet? I don’t have a blender but I really want to make this in the morning!

    • Iowa Girl Eats 01.04.2012

      I don’t have a MB – but I don’t see why not! :D

    • Shelene 01.04.2012

      The Magic Bullet can’t handle dense frozen fruit like bananas and strawberries very well, but things like frozen blueberries and raspberries are no problem. So if I make these in my MB, I often use a fresh banana and add crushed ice to get the same texture. Good luck and enjoy! Green monsters are the best!

      • Sarah 01.05.2012

        I make gm’s in my magic bullet all the time. I use frozen banana, frozen fruit, yogurt and water. The trick is to make sure there is enough liquid to help everything blend easier. Hope this helps!

  16. Ali 01.04.2012

    Love it!! The perfect post for today. I was drinking this exact thing this morning at work (mind you I work in a small gym) and all the people were thinking it looked disgusting and couldn’t believe that I would drink such a thing. They were actually gagging at me haha! They could NOT understand how it tasted like a milk shake! I will be forwarding this post to about 25 people now. Thanks!

  17. Lisa 01.04.2012

    I also use kale or baby kale. LOVE my smoothies!

  18. JV 01.04.2012

    Love green monsters! My usual contains frozen banana, Trader Joe’s Vanilla Almond Milk, spinach, cinnamon!, peanut butter or almond butter, a bit of vanilla protein powder.

  19. It took me forever to jump on the green monster bandwagon but I am SO glad I did. I was skeptical that they would not really taste good but holy cow they are awesome. I have never tried adding yogurt so I will try that next time! Maybe the yogurt will help it be more filling? Usually when I make a green monster I am hungry 2 hours later.

  20. Lauren 01.04.2012

    The greener the better. ;)

  21. Lindsay @ Chobani 01.04.2012

    Yum, we’re big fans of Green Monsters, especially when CHO’s in the mix. The banana taste masks the spinach and gives it a creamy, sweet and smooth taste. With health benefits to boot!

    Lindsay, Chobani

  22. Jeralyn 01.04.2012

    I like to add honey to mine for some extra sweetness :)

  23. Bob 01.04.2012

    spinach, frozen mango, banana, vanilla protein powder (or cows milk or yogurt), ground flax seeds.

  24. Foodiku 01.04.2012

    I would love to try this, but I’m crazy allergic to bananas. I wonder what I could sub . . . suggestions anyone?

    • Jill 01.04.2012

      You could probably just sub in any frozen fruit you like and maybe extra yogurt for some more texture?

    • Jan 01.04.2012

      Frozen mangos from Trader Joe’s might add a little sweetness like bananas but you might have to add a little honey or agave to match the sweetness.

    • Iowa Girl Eats 01.04.2012

      Frozen mangoes, raspberries or blueberries would be great!

    • julia 01.04.2012

      avocado would add that creamy texture, for sure. green smoothies are the unsung hero of delicious treats!

      • Theresa 01.05.2012

        Avocado is next on the list for my attempts… what else do you use?

    • I have used frozen peaches when I did not have banana and it worked very well. I think you could really sub any fruit you wanted!!! If you want to keep it green and not let it turn a muddy color you need to use light colored fruits (peach, manog, pineapple, apple, etc) rather than dark berries. :) I hope you try this out, I made one a few days ago and it was to. die. for.

  25. deana allary 01.04.2012

    I like to add frozen raspberries and fatfreelight wildberry crumb cake yogurt to mine. The best!

  26. Jan 01.04.2012

    The frozen mangos from Trader Joe’s are an awesome addition to the green monster for a little extra sweetness! enjoy!

  27. This smoothie looks delicious! Yours always look WAY greener than when I make them.

    Where did you get the cool dole cup?

    • Iowa Girl Eats 01.04.2012

      I actually got it when I went to the Dole healthy bloggers summit earlier this summer!

  28. Cari 01.04.2012

    This sounds soooo delish! I can’t wait to try it! Does it make any difference if the banana isn’t frozen?

  29. I need to enjoy more green smoothies. They’re so good for you and easy to make/drink.

  30. Kaycie 01.04.2012

    I LOVE green smoothies! I do pretty much the same recipe but add in some protein powder. Tastes just like a shake and it’s amazing you can’t taste the spinach!

  31. Just got some spinach in my CSA box today! I see a Green Monster in my near future! :-)

  32. Sarah 01.04.2012

    I love green monsters, I add 100% orange juice, frozen berries and ground flax to mine!

  33. Amy 01.04.2012

    I was a gun shy regarding these and then I made one, YUM! So good………………….!!!!

  34. Love love these.

    Tip for buying bananas – often grocery stores (at least my Hy-Vee does) will set out a cart with bulk bags of bananas that are past their prime – but really they are just fine. A few brown spots on the outside. Pick up a few bags (or if you are my husband – SEVEN!!) and begin the process of freezing them in batches. We peel them, break in half and freeze on cookie sheets, and then store them in a giant tupperware (or plastic bags).

    I find the bananas easy to slice with a good knife when they are frozen, so breaking them in half speeds things along.

    This is a super deal and you save a ton of money. Often, if you are lucky, you even get the organic bananas for dirt cheap.

  35. Sarah HS 01.04.2012

    I like 1 cup of frozen unsweetened mixed berries, 1 vanilla Greek yogurt, 1 banana, spinach and almond milk. Pure deliciousness!

  36. Jenny 01.04.2012

    I usually do spinach/kale, celery, water, apple, pear and half a frozen banana. lasts for three days and is so glorious!

  37. Megan Newcomer 01.04.2012

    I love green monsters! I make mine with almond milk, almond butter, chia seeds, spinach, and a frozen banana. So yummy!

  38. Kaycie G 01.04.2012

    Oh my gosh there’s another Kaycie spelled the same way as me and we both follow IGE no wayyy! HI NAME TWIN IF YOU READ THIS!!

    Excuse me, anyway, I am so pumped to try this. I am the worst at eating vegetables so this looks perfect!

  39. Jen F. 01.04.2012

    I’ve read about green monsters for quite some time and you might just be the person that convinces me to do it. Did you know there’s a blog totally devoted to green monsters?!!

  40. Teddi 01.04.2012

    I have to admit this looks scary to me, but I’m willing to try it. I really need more veggies in my diet and this would be a great way to get them.

  41. Hannah 01.04.2012

    I tried your green monster smoothie over a month ago and I’ve had one for breakfast everyday since! My family doesn’t believe me when I tell them that it’s actually amazing.

  42. Dream Mom 01.04.2012

    I have a smoothie every other day for breakfast. Most often, it’s 1 cup water, 1/2 cup organic berries, 1 frozen organic banana and 4 cups organic spinach. Love them!

  43. Theresa 01.05.2012

    Sipping on mine right now! Thanks, Kristin!
    Almond butter tastes terrific in these. For some added natural sweetness drop in some frozen dark cherries, shredded carrots, and frozen berries.

  44. Lani 01.05.2012

    I just wanted to tell you that I saw this yesterday, made it this morning…and had to jump on to tell you how delicious this is! I am drinking it as i type…it’s insane! It tasted just like a desert shake…and I got about 2 cups of spinach in mine! Thank you so much for the great idea!

  45. Erin 01.05.2012

    I keep seeing this recipe and I am still skeptical but I think I need to try it!

  46. Love Green smoothies, but I just cannot get into them when it’s cold out!!!

  47. I’ve always wanted to try one…you’ve given me the guts to now try!

  48. Katie 01.05.2012

    I prep mine the night before with 1/4 cup dry rolled oats, 1 cup vanilla almond breeze, 1 Tbs chia seeds, a dash of cinnamon and vanilla and a bananna. The next morning I add the spinach and blend.
    Oh, and all of this goes into a small mouth mason jar. The blade part of my blender fits on this so i just tip it upside down, blend then remove the blade and drink right from the jar :)

    • Iowa Girl Eats 01.05.2012

      I have been wanting to try that trick!! I will for sure do it next time!

  49. Micah 01.05.2012

    I have been wanting to make these for a long time. It’s a good way to get fruits and vegetables in. My only question — can I make it the night before? Will it keep in the fridge? Or is it best to make it right before I plan to consume it?

    • Iowa Girl Eats 01.05.2012

      I’ve frozen it overnight with great results, but never left it in the fridge. I think it’d probably be best to freeze it, or make it right before drinking!

  50. Em 01.05.2012

    Oh wow! I have never added peanut butter.
    Sounds like breakfast for today! Thanks!
