The best green smoothie with frozen banana, peanut butter and baby spinach. If you’re new to green smoothies this is the perfect recipe to start with.

If the thought of drinking kale, spinach, collard greens and swiss chard makes you cringe, please don’t leave just yet! I promise that you can create green smoothies that actually taste good and they’ll make you feel good too!

To be honest, I’ve always liked green smoothies, but never tried drinking them on a regular basis until recently.

And it’s been amazing!

I’ve made a a bunch of different green smoothies over the years and I always feel awesome after drinking them.

It makes sense considering leafy greens are one of the most nutritious foods you can eat. It’s one of the reasons I love incorporating one large salad a day, but putting greens in your smoothie is such an easy way to pack a lot of greens into one meal.

Benefits of Eating Dark Leafy Greens

I’m sure you’ve heard that greens are good for you, but did you know that greens are high in calcium, magnesium, iron, potassium, phosphorous, zinc and vitamins A, C, E and K? They’re also crammed with fiber, folic acid, chlorophyll and many other micronutrients and phytochemicals. The benefits of leafy greens are amazing. Here are a few:

  • Blood purification
  • Cancer prevention
  • Improved circulation
  • Strengthened immune system
  • Promotion of healthy intestinal flora
  • Promotion of subtle, light and flexible energy
  • Lifted spirit and elimination of depression
  • Improved liver, gall bladder and kidney function
  • Cleared congestion, especially in lungs by reducing mucus

Getting Started with Green Smoothies

  • Baby spinach has a mild flavor and is a great place to start! Add a handful or two of baby spinach into your smoothies then work your way up to adding a larger amount of spinach or different greens that are a little more pungent like collards and kale.
  • Use frozen fruit! Frozen bananas and mango add a nice sweetness, great texture and cover up the taste of the greens really well. <– Just make sure your bananas are ripe and that you peel them before freezing. I like to slice them in half (or in chunks) and put them in freezer-safe bags or storage containers before placing in the freezer.
  • I recommend using a high-powered blender like a Vitamix. If you don’t have one you can still make green smoothies, but you’ll probably have to deal with pieces of un-blended greens. Just be sure to check your teeth. 😉 For what it’s worth, I LOVE my Vitamix.
  • Remember that green smoothies don’t have to be green. When you include other colorful fruits (like berries) into the smoothie the color isn’t always green.
  • I’ve been using plant-based protein powder in my smoothies. My favorite protein powder brand is sweetened with stevia and that definitely helps to make the smoothie taste delicious.

One of my favorite green smoothies to date is this one with banana and peanut butter. This combo never disappoints and it’s delicious in this smoothie! I promise you won’t taste the spinach at all. I hope this post will inspire you to try a green smoothie, if you haven’t before and if you have, perhaps it will be a friendly reminder to add a green smoothie or two back into your routine. Drink up and enjoy all the great benefits!

  1. Ooo girl those green smoothies are my favorite color ;D the recipe you shared sounds awesome! I’ve been having smoothies for breakfast, and I was like you… Thought I couldn’t have a smoothie as a meal. But it’s nice because you can add whatever or take out whatever you want depending on your appetite or just how you’re feeling 🙂 not to mention it’s a great feeling knowing that your body is probably leaping for joy when you drink it!

    Cheers 🙂

    Also, I’ll email you about being included in that post you want to compile

  2. I’m easing into the green smoothie thing, I’ve just been adding a little spinach to my regular smoothies, increasing the amount each time. I’m up to about a handful of spinach and it’s not even noticeable, color wise or taste wise! I’m not sure I’ll ever go full-green smoothie like you, but I definitely see the benefits of adding in a little greens here and there 🙂

  3. I tried out your black bean burgers recently. I didn’t have any breadcrumbs on hand, so I ended up crumbling 2 ends of whole wheat bread instead, and they came out great! I’d send you a photo, but they are half devoured, so next time!

  4. I wish I could bring a blender to work so that I could have an afternoon smoothie for lunch or snack. That’d be a wonderful pick-me-up!

    1. Hey Robin. I don’t eat the skin of bananas. I know they are technically edible but they taste bitter to me.

  5. I love anything peanut butter so this smoothie looks fantastic! 🙂 Thanks for sharing! Be sure to check out my latest recipe-bean salad-Cowboy Caviar @

  6. I had a green smoothie for breakfast almost every day the month before my wedding – great to know you’re getting your greens and fruit in at the beginning of the day!

  7. Mmm! I’m a fan of green smoothies- especially with Sunwarrior these days. This post decided it for me- I’m going to have one for a snack today!

  8. I had a green smoothie for breakfast and it was the first one I’ve had in quite awhile! I need to get in a habit of having on for a snack. I’m the same when it domes to meals or snacks I like to chew something!

  9. It’s funny, the recipie that you shared is almost exactly the same one that I have nearly every day! I am loving the PB2 in smoothies! Sometimes I thicken mine up with a little 1/2 t of guar gum and 1/4 t of xantham gum from Bob’s red mill, which helps to give it more of an ice cream like consistency.

    1. Good idea! I have some xanthan gum that I use in smoothies every once in a while. I’ll throw that in next time. 🙂

  10. Green smoothies are the best. Definitely know what my afternoon snack is going to be today 🙂

  11. I need to eat more smoothies – this one looks amazing! I love my greens too and now that I’m eating Mila it will be a perfect vehicle!

  12. When I first added green smoothies into my diet, the first thing I noticed was that they reduced my cravings for sugar!
    I love your article, and really appreciate your comment about eating veggies that are not organic. I agree with you 100%. It’s so much better to eat greens, even if they’re not organic, than to not eat them at all. Not everyone can afford all organic foods, but fruits and veggies are so loaded with goodness that we should never give them up. Naturally, organic is preferable, but all greens will benefit our health. Also, I love your glass with the picture of the pooch! It rocks!

  13. I find that it’s helpful to juice the kale/collards with celery, cucumber, lime and/or a green apple before adding it to the blender. Once the greens are juiced, add the frozen banana and other additions as you would normally.

  14. Thanks for the recipe! Hubby and I bought a Vitamix on New Year’s Eve this last year and love it! We have been making smoothies ever since….we always put in 2 handfuls of organic spinach and 2 handfulls of broccoli, and 2 carrots, along with our fruit…we also add greek yogurt and 2 Tbsp. of Flaxseed meal….yummy….can’t taste the green veggies at all….love it! We also use frozen strawberries and frozen tripleberries…love how we feel….we’re in our 50’s!

  15. @Robin – Skin-ON bananas? Really?! I have a Vitamix, but I never considered putting bananas in with skin-on. I do use stems of kale, tho.

    1. I feel the same way Heather. Banana peels are technically edible, but they are so bitter!

      1. Frozen bananas are easy to peel. That’s what @Robin meant.
        I see peeling them before freezing as unnecessary work.

  16. I make green smoothies often and will try the green Elvis. Thanks for the link to Aimee DuFresne’s blog. I don’t know what she uses for juicing, but my Vitamix is a lot easier. Takes up less room, too. However we make the green smoothies, count me in for the ten day challenge!

  17. I have a green smoothie every morning as my breakfast. Great way to get in a couple of veggies and several fruits at one time and it keeps me full till lunch. I now carry my Vitamix with me when I go visit my parents so I can continue my morning smoothie. I have been looking at IIN and sitting on the fence about it but the more and more people I see who have been through the program I’m thinking it is the right thing to do. Saving now so I can pay for it!

  18. My wife and I have a green smoothie almost every morning for breakfast. Today I decided to actually measure the ingredients. Here’s our current favorite recipe (serves two):

    4 cups unsweetened almond milk
    Two servings matcha green tea powder
    Two servings whey protein powder (we use Jay Robb’s)
    3 cups spinach
    1.5 cups kale
    1/4 cup arugula
    1/4 cup frozen homemade broccoli sprouts
    Several sprigs of fresh mint
    One frozen cucumber
    One banana
    One tablespoon unrefined coconut oil


    I’m looking forward to seeing more green smoothie recipes here. Thanks for the info!

  19. Hi! I’ve been lurking for a little while, but I wanted to say that those green smoothies look soooo refreshing:) Question: I just moved to the UK and for whatever reason, it seems really hard to find fresh greens right now. Have you ever experimented with frozen spinach in a smoothie? Cheers!

    1. Hi Renee! I’ve never tried using frozen spinach but I think it world work best if you defrost it and make sure to squeeze out all the liquid before putting it in the smoothie. Although, maybe it would work well frozen too. Let me know if you experiment with it. 🙂

    2. Hi Renee, we’ve been using frozen spinach when we make green smoothies. After all, if you can put a frozen banana in, why not some frozen spinach. If you defrost it first you have to deal with all the extra slime (yuck, lol!) plus lose some of the goodness as it runs down the drain. We love cheese, spinach and garlic pizza and if we have spinach in the freezer we can make on the spur of the moment even when we’ve no fresh. Or stir it into risotto. Or pasta. Oh, sorry, we were talking about smoothies weren’t we … I got carried away, there, lol!

  20. One tip, especially when using spinach in a smoothie, is that heating/cooking the spinach releases more of its nutrients!
    I will put some water in a bowl and stuff a huge handful spinach and nuke it for 30 seconds. Then put it in the blender WITH the water too! : )
    I’ve also noticed that the slightly wilted spinach blends a little bit easier. My blender is almost 10 years old and manages it okay!

  21. Hi! I’ve been drinking smoothies for years now, and lately I can’t stop reading about these “green” smoothies. So, I finally tried one at home this morning. I followed your recipe (couldn’t believe I had all your ingredients!). And oh my! Why have I been so anti green smoothies?!?!? It was wonderful! 🙂 You’ve made me one happy green smoothie drinker today!

  22. If I have my green smoothie instead of my other breakfast option (granola, banana, and yogurt), I feel SO much more alert in the morning. I think those micronutrients in the spinach help a ton!

  23. I haven’t tried putting peanut butter and spinach in the same smoothie before, but now I want to! My toddler loves smoothies, so it’s a great way to sneak some veggies into him. 🙂

  24. Love love love green smoothies! I haven’t tried that combo before…sounds yummy!

  25. That juice looks so delicious and healthy. I wanna try that one. I am thinking to be a vegitarian. This one is perfect to start with.

  26. I love green smoothies! I have a hard time getting all my veggies in so making a smoothie with a couple handfuls of spinach is a great way for me to boost my leafy greens intake. I like making them with a banana + a bit of peanut butter + almond milk. Delicious!

  27. I haven’t made a green smoothie in a while because I have been on an Ellwood’s green juice kick, but I definitely need to reincorporate them back into my life. Wish I could whip them up at work as a 3PM snack! Maybe I will pre-make and store them in our office freezer??

  28. Classy, lady! I love drinking smoothies out of pint glasses, so you’re not alone. They feel extra fancy out of Belgian beer glasses!

  29. I love green smoothies, although i always have the same one: spinach, banana, almond milk. so delicious!

    I would much rather have them as an afternoon snack, but I work until 5. Do you have any recommendations for smoothie-drinking at work?

  30. That Green Elvis recipe is like what I have for breakfast every single day, unless one of my roommates is sleeping.. and I don’t want to wake her up with the sound of my vita mix 😉 haha

    I love the idea of having one as an afternoon snack. I wish I could take my blender to work!!! haha

    1. I’m not sure if a smoothie would last all day in the fridge, but I make my smoothies at home on my lunch break (around 12:30) and they keep in the fridge until around 3:30 or so. Some hold better than others – I think frozen fruits definitely help. Maybe you could try it one day and see…

  31. I had my first green smoothie for breakfast the other day and I was shocked by how long I stayed full! Definitely not “just a smoothie” 🙂 It’s such a convenient way to get more servings of fruit/veggies into your day.

  32. I love green smoothies! I make them every morning for breakfast. We do blueberries, spinach, almond milk, flax, protein powder and sometimes greek yogurt.

  33. I love green smoothies too! I know bananas are good for you, but the sugar content worries me.

    So I sub in 2 TBS of oatmeal soaked overnight in 1 cup almond milk (or usually 24 hours, I put one in when I take one out), and a bit of ice. It thickens it up very nicely!

    You’ve got to experiment some more with these, please! I’ve read about ones with sweet potato that sound awesome! But still “green” with spinich or kale.

  34. Love the recipe! When you say 1-2 Tablespoons of PB2, is it mixed with water or just the straight up powder?


  35. Had this guy for breakfast this morning with PB2 and Chocolate protein powder. It makes the color kind of not good but the taste was amazing! All you can taste is Banana, Peanut butter, and chocolate! It’s like having a treat for breakfast!

  36. Yum! I’ve been having a green smoothie every morning for breakfast for several months now and sometimes as a pre-dinner snack. I thought I would get sick of them, but my body craves the greens! Tastes really refreshing too. I’ve been loving coconut milk in mine which makes it like a ‘milk’ shake. Can’t beat the pb banana combo 🙂

  37. I found your blog from Tosca Reno’s blog! I just made the green Elvis smoothie, my first ever greenie..all I can say is Oh. My. Gosh. Hands down best smoothie EVER!!!!

  38. The Green Elvis was delicious! Couldn’t even taste the spinach! I added a little bit of Kale in mines! Thanks for the recipe!!

  39. Here is my green smoothie recipe that i’ve been using every morning for the last 5 years. I guess I should switch it up, but it tastes so good!

    2 large chard leaves
    handful of spinach
    1 banana
    1/2 apple
    1/4 cup frozen or fresh berries of choice
    1/2 cup orange juice or water
    3 tablespoons Raw Organic Whey protein (

    Bend it all in a blender and it’s an amazing way to start the day.

  40. Instead of adding juice or almond milk I add coconut water to my smoothies to sweeten them up. love your site!

  41. Hi-Just found your blog here – I tried to find the 5 day slim down you mentioned, but could not – can you reference that for me, please? Thanks!

  42. Hi really liking your blog. I am big smoothie enthusiast. I was just wondering why you recommend freezing fresh bananas and using them? Is it just for coldness and texture or is there another reason i’m missing? Thanks!

    1. To CR:
      I personally use frozen bananas mostly because I don’t want them to go bad over the period of time, but when they’re frozen, you can skip the ice step sometimes and it really doesn’t change the texture. I can assume that with non frozen bananas, it will be a tad more creamy, but when I use frozen bananas, it pretty much leaves the same texture.
      I hope this helps!

      – Hana

    1. I usually use the scoop that comes with my protein powder to measure protein powder, but I think it’s about 2 Tablespoons. 🙂

  43. It’s official. I am obsessed with your blog! I’m a second year grad student and have very limited time to prepare food on my own that isn’t frozen, but with a little bit of time and effort I have made a few of your recipes this weekend, and I feel SO energized that I will definitely keep continuing! It’s so worth it 🙂 I literally feel 10 times more energized!

    This green smoothie is life changing! I am very new to smoothie making but this one tastes amazing:) I really can’t believe that you can’t taste the spinach at all! This is a great alternative to eating salads all the time.

  45. Thank you for such wonderful info! Working on getting more green into my smoothie, and you have been a great inspiration. Know I want to find these bean burgers…

  46. Is a pint of green smoothie enough to have for lunch? I had a pint of my pint about an hour ago and I was full at the time but now I’m hungry again. I love spinach and I wonder if eating the food in the smoothie would be more filling than drinking it.

  47. Er … excuse me but … why ‘Elvis’?

    Yes, I tried the recipe and loved it, but I’m still left with the question.

    Just tried to make your green elvis, with kale instead of spinach. But I think I need a better blender. Can you recommend one?

  49. 5 stars
    I love this recipe!! For me, it makes almost the perfect smoothie. It’s a little on the thicker side, but if you don’t enjoy that, add milk! Also, if you aren’t into the strong vanilla flavor (like me!!), add only half a scoop of a few tablespoons of the protein powder!

    1. I’m so glad you love this smoothie recipe, Elizabeth! I really appreciate you coming back to leave a comment and star rating. <3

  50. That smoothie looks really great! Thank you for sharing the recipe. Keep up the great work!

  51. This is my go-to breakfast smoothie! Love adding a few shakes of cinnamon (for flavor and anti-inflammatory properties!)

    I hate waking up not knowing what to eat for breakfast, so getting this in my email made breakfast easy today! Peanut butter, banana + Tera’s Whey bourbon vanilla protein powder is actually my go-to when I do make smoothies but I never thought to add spinach. It didn’t add a spinachy taste but somehow it tasted better than when I make it without. I think I’m going to try the cinnamon oatmeal cookie smoothie next time!

    1. Ahh yay!! That makes me so happy to hear, Molly. I’m so glad you enjoyed this smoothie. Thanks for making it and for coming back to leave a comment + star rating. I so appreciate it. <3

    This is THE. BEST. Packed with healthy fats, fiber and protein, the PB and banana totally hide the spinach and the texture is so so smooth. I used PB2 powder and then added a tsp of good old Jiff for texture and a little fat. Soooo good. Adding this to my morning routine!

    1. Ahh yay!! So glad you enjoyed this smoothie, Elizabeth! Thanks so much for giving it a try and for coming back to leave a comment + star rating. I really appreciate it. 🙂

    I may or may not have made this three days in a row! Soo good, cant even taste the spinach. Looking forward to trying more of your recipes 🙂

    So yummy!! Tried with crunchy peanut butter and omitted protein powder, and it was the best!! Still a great snack without the added protein.

    I keep making this smoothie because peanut butter + banana with vanilla protein powder has always been my go-to breakfast smoothie. I never wanted to “ruin” it by trying to sneak in veggies but I can always trust an EBF recipe so I tried this and now it’s my go-to :). The spinach adds no additional taste but makes me feel so much more energized throughout the morning. Tera’s Whey Bourbon Vanilla is a great tasting clean whey protein if anyone’s in need of a recommendation.

    Perfect blend of greens and peanut butter! Had to sub kale for the spinach and it tasted great! Will be making again!

    I absolutely love this smoothie because you get your greens in but it’s disguised by the amazing taste of the banana and the peanut butter. I used a whole banana because I like my smoothies on the thicker side. I would highly recommend this delicious smoothie!

    I was surprised it tasted so good with it being green! Trying to start healthy today after all the rich holiday foods. I used peanut butter powder like you mentioned as a substitute for less mess.
