Green monster smoothies are monster-sized, veggie-loaded green smoothies made with lots of fruit and vegetables for a nutritious meal or snack. I like to add some healthy fats and protein to mine to make them more substantial.

Best Veggies for Green Monster Smoothies

I like to make my green monster smoothies a challenge to see how many veggies I can add while still having it taste sweet and delicious. My go-to veggies are kale, spinach, celery and zucchini. They’re all quite mild in flavour but add so much amazing nutrition that I just love filling the blender to the brim with as many as I can. To make your own green monster smoothie, choose any 4 of the following green veggies:

  • handful of kale
  • handful of spinach
  • handful of romaine lettuce
  • handful of swiss chard
  • 1-2 ribs celery
  • 1/2 a small zucchini
  • 1/2 a cucumber

Those are just my top pics some other good ones are a few pieces of broccoli, chopped beet, chopped carrot, frozen cauliflower pieces, fresh ginger root or a handful of fresh parsley. You can check out my post on the best vegetables to add to smoothies for more ideas.

Best Fruit for Green Monster Smoothies

Here’s the fun part: you can use any frozen fruit you feel like and mix-n-match every time to create different flavours. My go-to, and what I used in the recipe below, is a mixture of frozen peach and strawberry. I like these two picks because they’re lower in sugar than banana or mango, for example. That being said, banana and mango are both delicious and I do use them sometimes.

Frozen banana adds the best, creamy texture and mango adds such as nice sweetness. Blueberries are excellent too and are low in sugar and high in antioxidants. To customize your green monster smoothie, combine any of these frozen fruits up to 1.5 cups:

  • Strawberry
  • Raspberry
  • Peach
  • Mango
  • Pineapple
  • Banana
  • Blueberry
  • Orange
  • Mixed Berries

Some delicious combos are raspberry and peach, mango, orange and pineapple for a tropical smoothie, blueberry banana and strawberry, raspberry and blueberry for a triple berry flavour.

When I use orange, I usually use 1/2 a fresh navel orange but the rest are best used frozen. I like to keep my freezer stocked with frozen banana chunks, frozen blueberry, frozen mango chunks, frozen sliced strawberry and frozen sliced peaches. I also usually have some frozen zucchini and cauliflower for smoothies in there too.

Green Monster Smoothie Nutrition Boosters


I always add 1 scoop of vegan protein powder for sweetness, creaminess and added protein. My favourites are vanilla Vega Performance Protein, North Coast Naturals Vege PRO-7, Naked Pea Protein Powder and Bob’s Red Mill Vegan Protein Powder. I haven’t tried that many others to be honest though, so if you have a favourite, let me know in the comments1

Healthy Fats

I like to add some healthy fats for a source of essential fatty acids, added satiety, extra vitamins and minerals and to help keep blood sugar levels more stable.

Add 1-3 tbsp of healthy fats:

  • Hemp Seeds.
  • Ground Flax.
  • Chia Seeds.
  • Pumpkin Seeds.
  • Sunflower Seeds.
  • Nuts.
  • Nut Butters.
  • Coconut Butter, Shredded or Flaked Coconut.
  • Tahini or Sunflower Seed Butter.
  • Avocado.


Next is adding 1 or 2 superfoods. This category is totally optional but I like adding some fun superfoods for a little boost in nutrition. Her are my favourites. I’ve listed some of their benefits so you can choose based on your nutritional needs. You can also check out my post on the best superfoods to add to smoothies and my post all about adaptogens for more options.

Choose 1-2 superfood powders:

  • Spirulina. Protein, iron, vitamin A, K, manganese, beta-carotene and chromium.
  • Moringa Powder. Vitamin A, vitamin C, calcium, potassium.
  • Maca Powder. Hormone balancing and energy.
  • Chlorella Powder. Detoxification, hormone balancing, protein, iron, magnesium, amino acids.
  • Camu Camu Powder. High in vitamin C.
  • Boabab Powder. Rich in antioxidants, high in potassium, prebiotic fibre.
  • Adaptogens as needed. Chaga, reishi, ashwaganda, rhodiolo and shativari are some of my favourites.


You can use water, any plant-based milk or a combination of the two. I usually just use water but I like store-bought unsweetened almond milk too for the added calcium and vitamin D.

Well, I’ll leave you to it. There’s not much else you need to know to make green monster smoothies. Throw in a bunch of green veggies, add some fruit, add some protein, add a healthy fat if you want…blend, pour, drink it back!

Oh, one last thing. I love making these super thick and eating them as smoothie bowls. Just reduce the liquid to 1 cup and blend until smooth. Scoop the mixture into a bowl, top with your favourite smoothie bowl toppings.

Some of my favourite toppings are goji berries or mulberries, peanut or almond butter, cacao nibs, chopped figs or dates, nuts, seeds, coconut, vegan cacao cereal or granola.
