Fortify your breakfast or snack time with this peanut butter banana green smoothie! This green smoothie recipe is super-nutritious and is made with baby spinach leaves and flax seeds for extra fiber and iron.

I love smoothies for breakfast, after-dinner dessert, or even as a post-workout snack. Not only are they refreshing and make me feel energized, but it is a delicious (and genius) way to eat more fruits and veggies. In fact, when I make a smoothie, I try to think of all the different types of things I can add to it to make it even more nutritious!

Sometimes, I'll add some honey or maple syrup to naturally sweeten my smoothies. That's really only when I am using a lot of tart ingredients. But, with this green smoothie recipe, the banana and peanut butter are so sweet that you don't need any additional sweeteners.

Key Ingredients For Peanut Butter Banana Green Smoothie

I highly recommend always using the freshest ingredients you can find. That's what will make this smoothie taste the best!

Here's a little extra information about what I used in my green smoothie recipe.

  • Bananas: Try to use ripe bananas. They will puree easier and offer some of that natural sweetness when combined with the rest of the ingredients.
  • Spinach: For this smoothie, only use fresh spinach leaves. Frozen or canned spinach will not have the right texture for the smoothie.
  • Yogurt: I used nonfat Greek yogurt because it is thick and creamy. It is the perfect base for lots of smoothies! If you use regular yogurt, it won't be as thick, but it will still taste delicious.
  • Flax Seeds: They add fiber to the smoothie without altering how it feels. You can skip them if you want, but I recommend adding them if you can.
  • Almond Milk: Always use unsweetened almond milk to keep the calorie count down. If you use sweetened almond milk, you'll notice the smoothie tastes extra sweet.
  • Vanilla Extract: If you use vanilla almond milk, you can skip this ingredient.
  • Peanut Butter: Try to find natural peanut butter that doesn't have any added sugar. Also, instead of peanut butter, you can use any type of nut or seed butter you like.

Recipe Tips And Ideas

Follow these tips to make sure that this smoothie turns out sweet and perfect every single time.

  • Use frozen banana chunks. If you do, you won't have to add more ice.
  • This recipe makes two smoothies, so if you're just making one, use half the amount of the ingredients.
  • For an even sweeter taste, add a few Medjool dates, some honey, or maple syrup. You could also use a sweetened yogurt, like vanilla, to add sweetness.
  • To make it thicker, add extra frozen bananas or more yogurt.
  • Smoothie too thick? Add some more almond milk a little bit at a time until it's at the consistency you like.

What To Serve With a Green Smoothie

What is your favorite thing to eat with a smoothie? I personally like bite-sized snacks!

Smoothies are something I drink when I am swamped or don't have time to sit down for a complete meal. So, on those days, I'll have a banana quinoa chia muffin with my smoothie. That combo is packed with tons of fiber!

If you want something with more protein, try it with some ham and egg muffins. They are portable and can go with you out the door.

Frequently Asked Questions

Here are some questions I frequently get asked about by some readers…

Is it ok to drink green smoothies every day?

Yes, this recipe is packed with nutrition so that you can enjoy it every day! It's high in iron, potassium, calcium, fiber, and protein.

Tip: If you want it to have even more protein, add a scoop of protein powder.

Can I use chia seeds instead of flax seeds?

Yes, you can replace flax seeds with chia seeds. Just be sure to drink your smoothie in one sitting! If you use chia seeds and try to store leftovers in the refrigerator, the chia seeds will create a pudding-like texture.

Can I use these ingredients as frozen smoothie packs?

Yup! You can freeze the ingredients in resealable freezer-safe bags. This is a fantastic way to preserve fresh ingredients for smoothies if you don't think you'll have time to use them.

What other types of milk can I use?

I recommend using your favorite type of milk in this recipe. Other than almond milk, I like to use coconut milk or oat milk in smoothies. You can also use whole dairy milk if you don't have an aversion or sensitivity to it.

Note: If you make any changes to the recipe, my nutrition facts won't apply.

Does it taste like spinach?

No, that's the beautiful thing about this recipe! The banana and peanut butter are the main things you will taste. The spinach flavor basically disappears, but you still get to reap all of the nutritional benefits!
