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!

I almost feel guilty enjoying one of these babies, as it tastes like a sweet, indulgent ice cream shake. It’s perfect for breakfast, lunch or even a snack.

Try throwing in different kinds of greens, protein powder, and any frozen fruit or berry combo under the sun. The sky’s the limit with this ultra-healthy, not-healthy-tasting Green Monster Spinach Smoothie!

    I made my first one this morning and it was fabulous! I added two strawberries since I had them and it turned out amazing.

  2. sara 01.05.2012

    My new fave combo is banana, pineapple, yokids organic strawberry yogurt, spinach and ice. Awesome!

  3. Jennie M. 01.05.2012

    I use this one with spinach, bananas, and green grapes:

    It is a little chunky with the apple, so I’ve omitted that ingredient as of late.

  4. Stacey 01.05.2012

    I’ve loved these since I first saw them on your blog about 2 years ago – they are aaawesome! I love lemon yogurt with blueberries with it. Kinda looks odd with the blueberries ie: grey :) But it tastes awesome and so good for me!

  5. northwoods mom 01.05.2012

    Recently discovered adding spinach to my morning smoothie, it is awesome. Other things that I add to your already great recipe: organic rolled oats and substitute almond butter (love the Barney Butter brand) for the peanut butter, and some ground flax, chia seeds and wheat germ that I have all mixed in the frige for salads etc…..WOW

  6. northwoods mom 01.05.2012

    I am in the market for a new blender/food processor. Any body have a recommendation?

    • Carlye 01.09.2012

      I just got a Ninja Kitchen System! I love it so much! It is a blender, food processor, ice cream maker and dough mixer in one!

  7. CycloneMom 01.05.2012

    Any good substitutions for the yogurt? I am off all dairy while nursing my baby. I could try soy yogurt, I guess, but I know the Greek yogurt provides more protein.

    • Iowa Girl Eats 01.05.2012

      I’ve made them without yogurt lots of times, adding protein powder and chia seeds instead. It’s just as thick!

    • Ann 01.05.2012

      Try amande brand yogurt. It is made with cultured almond milk. :)

      • CycloneMom 01.05.2012

        That looks delish, but looks like the closest place that carries it is 45 min away. Will have to try without. :)

  8. Jordan 01.05.2012

    I have these for breakfast every day! My combo is flax seeds, protein powder, spinach, mixed frozen berries and milk.

  9. Ris 01.05.2012

    This sounds amazing! I will definitely be making one of these guys very soon!!

  10. This looks delicious, I will definitely by trying this soon!

  11. Hallie Sawyer 01.05.2012

    I love making these! I use greek yogurt and almond milk also but I usually add frozen blueberries or fresh strawberries if I have them on hand. The other thing I add is a bit of fresh ginger. I love the zing!

    I will check your recipe out though. It looks great!

  12. Amanda 01.05.2012

    It looks and sounds scary…..I’ve never thought of making a smoothie with spinanch!! :/ if I gather some guts I may try it someday

  13. Doug 01.05.2012

    Hy-Vee frozen blueberries = Purple Monster. Spinach, soy milk, vanilla protein powder, yogurt, and the berries. Tastes great…just might have to pick a few seeds from your teeth after :)

  14. Lisa Jones 01.05.2012

    Ok, Iowa Girl, I’m gonna try it! I’ll let you know how it turns out! BTW, pinned it on Pinterest!

  15. Danielle 01.05.2012

    This looked like something I would love and I did! Omg so good! This is great for my anemia too. Thank you!

  16. Deb 01.05.2012

    I’m so glad you posted this. I was looking for soft foods to eat for after I get my wisdom teeth removed tomorrow, and this sounds like the perfect fix!

  17. I’m obviously in love with spinach :) I always include chia seeds but there are so many combinations to try, it makes my head spin! Thanks for sharing!

  18. Dawn 01.05.2012

    I have never been too sure of this concept. I like all the ingredients, just not all in one drink. Not too appetizing for my palette!

  19. VeggieGirl 01.05.2012

    In summer (cos in Winter I get brain freeze) I LOVE my green monsters and they contribute to my health SO much! I actually drink a Bolthouse Farms Mango protien smoothie every morning for breakfast- its quick and full of goodness and I havent been sick yet this winter!

  20. I love smoothies but have always been weary to try one with spinach. After reading this though (and the comments) I think I will try it tomorrow for breakfast!

    • Ok I tried it this morning and loved it! Didn’t taste like liquid salad at all! HA! Definitely going to work this in to my morning routine! Thanks for the tip!

  21. Really can’t wait to try this- I hope I can my hubby to drink this too…..thank you!!

  22. Samantha Cahalan 01.05.2012

    Love your blog – I can’t wait to try something that’s healthy and tasty!!

  23. De 01.05.2012

    I have a green monster smoothie every morning during the warmer times of year, but in the winter for breakfast I have spinach scrambled into an egg. But now I want a green monster for a snack. Might be that it is 40 degrees up in MSP…

  24. Add an orange or clementine (or just OJ) and get a creamsicle flavor!!

    Also, I don’t know if it’s just me or my connection, but every time I go to your blog, my computer freezes while your pictures in the header load…I don’t have a problem reading your post in Greader, but just when I go to the page…

  25. tonya 01.05.2012

    would it be as smooth and thick without the pb or banana? i’m not really a fan of either one. can you taste them at all?

    • Iowa Girl Eats 01.05.2012

      You could use ice instead of the banana, and leave out the peanut butter if you want!

  26. Rachel S. 01.05.2012

    Yes! I finally tried one right before the holidays. I love it! I have one for breakfast every morning on the way to work. I can put everything in the blender the night before and just hit the button in the morning.
    The recipe I use is:
    1/2 banana
    2 TBS. peanut butter
    3/4 cup unsweetened vanilla almond milk
    handful of spinach
    4-5 ice cubes
    1 scoop of vanilla protein powder.

    It really does taste like a milkshake!

    • Iowa Girl Eats 01.05.2012

      That’s a great idea to put everything in the blender the night before!

  27. Luciana 01.05.2012

    Silly question, but does it taste very banana-y? I’m not a banana fan, so I always shy away from smoothies. But I’m really tempted to try this. Thoughts?

    • Iowa Girl Eats 01.05.2012

      Mmmm – I don’t think so, but I like bananas, so I’m not sure I focus on the flavor really. Does that make sense?

    • I don’t particularly like bananas and I didn’t mind it. I think you taste the yogurt and peanut butter more than anything.

  28. Luciana 01.05.2012

    Totally, thanks. And whatever, it can’t hurt to try it once!

  29. I have never had a Green Monster before! Normally the recipes I see don’t look that great, but seeing yours makes me want to try to make this. I love peanut butter and banana together!

  30. Allison 01.05.2012

    I’ve been meaning to try making a green monster! I love all of those ingredients but what’s stopping me is our ancient blender- don’t know how smooth it would come out :/

  31. I LIVE for Green Monsters and have one every morning! I usually add a scoop of protein powder in as well (SunWarrior Chocolate – so tasty!) so mine turn out a sludge-y brown color, but still taste delicious! Adding frozen strawberries gives it a delicious taste too!

  32. Katy 01.05.2012

    I was brave and tried this today. It really does taste very good. I added some frozen blueberries and strawberries. Thanks for the inspiration!

  33. Yum!! I make these almost every morning! SO good!

  34. Kristina 01.05.2012

    I have never tried a spinach smoothie and up until 2 seconds never would have (“ewwww!”). But you haven’t steered me wrong yet. 10 grams of fiber!? I won’t be hungry all day.

  35. Amy 01.05.2012

    THANK YOU FOR THIS RECIPE!!!! Just what I need to start 2012 off right :)

  36. Celina 01.05.2012

    you HAVE to try a green monster with FROZEN SPINACH CUBES! It makes it thicker and colder without watering it down with ice cubes!

    • Barb 01.05.2012

      How do you make frozen spinach cubes? I was actually wondering if I could somehow freeze the spinach along with the fruit and yogurt (frozen in an ice cube tray) and put it individual ziploc baggies.

  37. I’ve never been much of a smoothie girl, but that does sound really good! I might have to give it a try.

  38. […] must admit, I borrowed the recipe from my favorite blogger, Iowa Girl Eats, but for good reason. These ‘Green Monster’ drinks are SO tasty and the health benefits […]

  39. melissa 01.05.2012

    How do you get it to come out so smooth? I have a pretty decent blender and my green smoothies come out without any chunks or anything but there are still always little bits of spinach leaves.. I don’t see any of that in yours?

    • Iowa Girl Eats 01.07.2012

      My blender has a “liquify” setting that gets it super smooth!

  40. Casi 01.05.2012

    WOW what beautiful pictures of this highly nutritious smoothie. I want one and I want one NOW. Making this very soon, thank you :)

  41. […] Green Monster Spinach Smoothie! […]

  42. Kate Cremisino 01.05.2012

    This looks amazing. I am 20 weeks pregnant and love a good way to eat spinach. I ate tons before pregnancy and for some reason haven’t during pregnancy. Shame on me!! Thanks for the post!! I SO look forward to making this asap and having it as a staple in my diet!

  43. Elle 01.06.2012

    I LOVE green smoothies. I make one in the morning to take to work with me. My favorite is spinach (or kale), banana & pineapple. I also use soy milk and add protein powder. I sometimes swap the pineapple for a granny smith apple. I used to have an afternoon slump that tempted me to use the nap room at work, but since I started having one of these mid morning my afternoon slump has disappeared.

  45. Linda W. 01.06.2012

    2 organge and 2 apples, juiced, then added to 2 sliced frozen bananas in the blender with vanilla whey protein and a couple handfuls of spinach is the current fav.

    The options are endless. Use whatever you like or have on hand and need to use up. Clementines are very good instead of oranges. Like some tang? Add lemon or lime. Out of spinach? Use Romaine or kale. Don’t have a juicere? Use cranberry juice, apple juice or orange juice.

  46. Kelly 01.06.2012

    Just made my first green monster today for lunch. Amazing! It’s gonna be hard to wait til tomorrow for my next one ;)

  47. Deanna 01.06.2012

    I just made this and it’s awesome. Even more crazy…my three 5-year olds watched me make it, tried it and liked it! They were mad when I told them it was my lunch and I wasn’t sharing…guess I’ll be making that again. :-)

  48. Andrea 01.06.2012

    i love your recipes and will make this smoothie – maybe my kids will eat it too!
    can you provide the fat & carb nutrition?

  49. CaraLee 01.06.2012

    I am definitely going to try this when I get back to school! I have been itching for a way to get my fresh greens in other than eating salad! Thanks for sharing with us:)

  50. Lindsey 01.06.2012

    This looks so good! I’m a vegan though so I’ll have to not add the yogurt, any suggestions on a different thickening agent?
