    This watermelon banana smoothie is creamy, yet refreshing, sweet and a balanced snack. Packed with over twenty grams of protein and seven grams of fiber, this banana watermelon smoothie will keep you full and satisfied for hours! (Plus it's low maintenance - no need to freeze the watermelon beforehand!)

    Why You'll Love This Recipe

    • This watermelon banana smoothie is sweet and refreshing, between the juicy sweet watermelon and banana.
    • It's creamy, but not overwhelmingly so - more of a light creaminess from the banana and cauliflower.
    • However, with some added veggies, protein, healthy fat, and fiber, this smoothie is very balanced and can help support more even blood sugar and energy levels.
    • With over twenty grams of protein and seven grams of fiber, this smoothie makes for a filling snack (or part of a meal - you choose how you want to enjoy it!).

    Watermelon Banana Smoothie Ingredients

    • Watermelon - watermelon is the star of the show! Sweet, juicy, and creamy -- unlike other recipes, you don't need to freeze it ahead of time. The fresh juiciness adds to the consistency of the smoothie.
    • Banana - frozen banana slices add extra sweetness and creaminess to this smoothie. You can cut a banana into coins and freeze, or buy pre-chopped frozen banana coins at the store. And while this isn't my preferred method, if you only have fresh banana, try adding half a cup of ice to the smoothie.
    • Cauliflower - I like to add a little vegetables to my smoothies. It's a great way to add an extra serving of produce, as well as more fiber, volume, vitamins, and minerals. Frozen cauliflower rice blends great!
    • Protein powder or Collagen peptides - This is a great way to boost the amount of satiating protein in this smoothie without adding yogurt (which overpowers the other ingredients here). I personally prefer an unflavored collagen peptides in this smoothie, but my husband's favorite was a vanilla whey protein powder. P.S. If you want to learn more about the benefits of collagen - and potential side effects - check out my collagen article!
    • Chia seeds - I know chia seeds in smoothies can be polarizing, so if you hate it - skip it! Find nutrition to fit your needs, including your preferences! But I love adding a tablespoon of chia seeds to boost the healthy fats and fiber.
    • Milk - use whatever kind of dairy or plant milk you prefer to drink (note that the nutrition for this banana watermelon smoothie was calculated using unsweetened almond milk, so nutrition stats will vary based on what you use).

    Top Tips for Making a Banana Watermelon Smoothie:

    • My number one smoothie making tip is to always blend longer than you think you need to! Think your smoothie is blended? Blend at least thirty seconds to a minute longer. It'll result in an even smoother and fluffier smoothie.
    • When freezing bananas, chop them into smaller pieces or slice into coins (the thinner they're sliced, the faster they freeze and easier they blend). Lay them flat on a baking sheet lined with a silicon baking mat (for easier removal and clean up!). Place banana slices in a single layer on the lined baking sheet, then freeze for at least 1-2 hours. When solid, transfer to an airtight bag or container and store in the freezer up to three months. Or you can buy pre-frozen at the store if a little convenience makes healthy eating easier for ya, no shame!

    What's the Best Blender for Smoothies?

    I always advocate for using what you have or what's accessible to you - so the blender you've got is a great place to start!

    That said, if you make a lot of smoothies and are ready to up your smoothie game (and have the budget for it), I highly recommend investing in a high-speed blender to blend even the toughest of ingredients into the creamiest, smoothest smoothies. I recommend something like a Vitamix or Ninja!

    How to Turn This Smoothie Into a Meal

    One fun way to turn this smoothie into a meal? By turning it into a smoothie bowl! Pour your smoothie into a bow and topping with your favorite smoothie bowl toppings. I'd recommend adding more healthy fat, like some nuts, nut butter, or shredded coconut. Add a few slices of fresh or dried fruit for a little extra fun and color!

    Alternatively you could pair your smoothie with something like toast and nut butter, scrambled eggs, or a sandwich.

    Watermelon and Banana Smoothie Nutrition:

    Made with collagen peptides, this watermelon banana smoothie contains 229 calories, 23 grams of protein, 5 grams of fat, 28 grams of carbohydrate, and 7 grams of fiber.

    And containing at least 10% of the recommended daily intake, it's also a great source of iron, magnesium, manganese, phosphorus, potassium, and selenium.

    With 20% or more of the recommended daily intake, this watermelon smoothie is an excellent source of vitamin B6, vitamin C, vitamin D, vitamin E, vitamin K, calcium, and copper.
