Why you’ll love it:

This spinach cucumber smoothie is jam-packed with fiber, antioxidants, and vitamins to boost your immune system.

But just as importantly, if not more, it tastes DELICIOUS! It’s naturally sweet and refreshing from the cucumber and pineapple, with a vibrant green hue from the spinach.

It’s my favorite detox smoothie and it’s naturally dairy-free, gluten-free, and refined-sugar-free.

Key Ingredients:

This cucumber smoothie calls for six simple ingredients. Here’s what you need:

Ingredients for spinach cucumber smoothie.

Banana – Always use a ripe banana for smoothies. Underripe bananas taste chalky and bitter, so they won’t give you a sweet, creamy result.

Frozen pineapple – This is what thickens your smoothie! It’s important to use at least one frozen ingredient. Sweet and tangy pineapple pairs well with greens, especially mild spinach.

Cucumber – I prefer to peel the cucumber, but if you don’t mind bits of peel in your smoothie, you can leave it on. Regular or English cucumbers both work great.

Spinach – For a smoother blend, use baby spinach, but regular works fine too. Spinach adds a boost of nutrients without altering the flavor or texture too much.

Lime – I love to add a squeeze of fresh citrus to fruit smoothies. It makes the flavor of the fruit pop! Always use fresh lime juice. I keep limes in my fridge at all times.

Orange juice – For a tangy sweetness! For the healthiest option, use fresh squeezed orange juice that’s not from concentrate.

Blend until creamy and smooth!

Health Benefits of a Green Cucumber Smoothie

This green smoothie is loaded with nutrients! Check out these awesome health benefits:

  • It’s loaded with antioxidants. Leafy greens like spinach help prevent cancer and reduce the damage to your cells.
  • It’s low in calories but nutrient-dense! Both spinach and cucumbers have less than 25 calories per 100 gram serving.
  • It supports a healthy gut. Spinach is high in insoluble fiber which can help prevent constipation and improve digestion.

Variations & Substitutions:

Smoothies are easy to customize! Try one of these delicious variations:

  • Fruit: Frozen mango, apple, or kiwi would all taste great in this smoothie. You could even add avocado to make it creamier.
  • Yogurt: Add a scoop of unsweetened Greek yogurt for a creamier texture.
  • Greens: If you don’t have spinach, you can swap it with kale. Just be sure to remove the tough stems.

Smoothie Making Tips:

  • If the smoothie’s too thin, add a few pieces of frozen pineapple to thicken it up.
  • If the smoothie’s too thick, add a splash of orange juice to thin it out.
  • If possible, use frozen fruit instead of ice to thicken a smoothie. Ice melts faster and has a grittier texture.

Storing Tips:

Technically, you can store smoothies in the refrigerator for up to 24 hours after you make them. But I don’t recommend it. In my opinion, the smoothie doesn’t taste as good after a day in the fridge and it only takes 5 minutes to make it fresh!

However, if you have leftover cucumber smoothie, it makes delicious smoothie pops!

Just pour the smoothie into a popsicle mold, add popsicle sticks, and freeze for later. My kiddos love smoothie pops!


What are the benefits of a cucumber spinach smoothie?

A cucumber spinach smoothie is a great way to pack in nutrients! Both cucumbers and spinach are loaded with disease-fighting antioxidants, important vitamins, and insoluble fiber. The kind of fiber that aids in digestion and prevents constipation. This smoothie is also dairy-free and refined-sugar-free.

Do you have to peel cucumbers for smoothies?

Nope! You don’t have to peel cucumbers for smoothies. You can leave the peel on for the added nutrients, but keep in mind the smoothie won’t be quite as smooth. There will be bits of peel in it. If you don’t mind a little bit of texture, leave the peel on! If you like a smoother blend, peel the cuke.
