Before a day of celebrating and an evening of trick-or-treating, fuel your little ones with a nourishing 4-Ingredient Monster Green Smoothie! It’s a fun and festive blend of simple, wholesome ingredients — and it actually tastes delicious!

I have shared a lot of smoothies on this blog, but it has taken me years to post a GREEN smoothie recipe! After all, I had to be really sure that my green smoothie would not only taste amazing, but that the kids would eat it! When a beverage is the color of a scary green monster, you know that it better be GOOD!

This Monster Green Smoothie Is A Fun Way For Kids To Eat Nourishing Foods

Smoothies have become so darn complicated these days. From supplements like collagen to protein powders, chia seeds, and nut butters…the list of potential “add-ins” is totally out of control! Not that there’s anything inherently wrong with that stuff — I just don’t think it’s necessary for my kids. Instead, I stick with the high-quality basics that I know will nourish their active bodies with natural ingredients and a variety of vitamins and nutrients.

This Monster Green Smoothie takes advantage of 4 staples that we always have in our kitchen, which means that I can whip it up on any busy morning. Five minutes later, the boys (and I) can be sipping on a thick, creamy, and sweet blend of fruits, veggies, and Horizon Organic milk.

Horizon’s milk is a good choice for our family and for the environment. The milk comes from cows not given growth hormones or antibiotics, raised on farms that follow sustainable organic practices. Plus, with 8 grams of protein in every 8 ounce serving, it adds extra staying-power to the green smoothie!

Frozen banana, baby spinach leaves, and orange juice round out the list. There’s no added sugar necessary, since the fruit and fruit juice gives the green smoothie just the right amount of natural sweetness. The KEY to a thick, creamy, milkshake-like consistency is definitely the FROZEN banana. Don’t skip that part! I like to slice overripe bananas whenever I find them on my counter, stash them in individual plastic baggies, and freeze them for green smoothie mornings!

The baby spinach adds an obvious nutritional boost, but it also lends a green tint to the drink. You can take it from these guys: there’s NO HINT of spinach taste in the finished product!

The boys love this monster-themed breakfast (no matter what time of year I serve it), and they certainly never complain about consuming their veggies in this form! It’s a fun way to incorporate leafy greens into another meal!

Keep your mornings simple, easy, fast, and soul-satisfying with a nutrient-dense smoothie to start the day!

And for a bit of added fun on the holiday, definitely try a candy eyeball garnish in your child’s green smoothie. It’s a simple touch that makes this treat spooky enough for Halloween!

  1. How cute are these smoothies?! I would love to be sipping on this! It took me a while to get into green smoothies too…I had to make sure it was green, but not too green in flavor. Your version sounds perfect, and so fun for the kiddos!

  2. 4-Ingredient Monster Green Smoothie!!! It would be amazing!! The ingredients are very simple & nutrients dense. Best for busy mums like me. My two kids (and I ) also crazy about smoothies. But they don’t like the green taste at all. But your idea is perfect. I would definitely try this version of green smoothies for my kids and I will notify you of further updates.
