Breakfast isn’t just for smoothies Have you tried making your own fresh fruit juice for breakfast yet? We recently purchased a juice extractor and have been giving it a workout making our own fruit juices for breakfast. This peach juice is one of the first recipes we developed for the site, and we instantly fell in love with it. We also share a recipe for making a healthy and delicious peach crumble dessert that you can make with the pulp. You can feel good knowing that not only are you making a healthy juice without the preservatives and added refined sugar, but nothing will go to waste! We are looking forward to sharing more fresh juice recipes with you!

What You’ll Love About This Recipe

Quick and Easy. With just a few simple ingredients and minimal preparation, this smoothie can be whipped up in minutes, making it a convenient option for busy mornings or as a post-workout snack.
Refreshing Flavor. The combination of watermelon and banana creates a refreshing and fruity flavor that is perfect for a summertime treat or a revitalizing snack.
Nutrient-Rich. This smoothie is packed with nutrients from the fruit and yogurt. Bananas are a good source of potassium and fiber, while watermelon is hydrating and rich in vitamins A and C. Greek yogurt adds protein and probiotics, making this smoothie a nutritious choice.
Versatility. This recipe is versatile and can be easily customized to suit individual preferences. You can adjust the sweetness by omitting or reducing the brown sugar, or you can substitute ingredients like frozen yogurt or dairy-free alternatives for a vegan version.

Ingredients

1 medium banana. Sliced. You should end up with approximately ¾ cup of sliced banana.
2 teaspoons brown sugar. Light or dark. Optional. For a sugar-free option, try Swerve brown sugar substitute. It has zero net carbs and no calories. I did not include the brown sugar in the ingredient photo because this is part of an optional step. I have included this step in the recipe because it will bring out the flavor of the banana. However, you can omit this step altogether, and the smoothie will taste just as good. 🙂
½ cup vanilla Greek yogurt. You can substitute frozen yogurt or a small sliced banana for a dairy free vegan version. If you don’t mind a thinner smoothie, you can also substitute a nut milk like almond or this simple and easy homemade walnut milk. It is also dairy-free and vegan.
1 cup chopped seedless watermelon. Chopped into 1 inch cubes.
Optional: Add 1 tablespoon of nut butter, like this delicious homemade walnut butter for a natural protein boost!

Instructions

The first two photos show an optional step. You do not have to do this, but it does help to bring out the banana flavor. Feel free to skip to Step 2 if you don’t want the added sugar or don’t want to bother with this step. This smoothie will taste just as delicious!

Variations

Watermelon Banana Smoothie Bowl. Add ½ cup of uncooked rolled oats or chia seeds to the blender. This will absorb some of the liquid and make the smoothie thicker. It will also provide some additional nutrition!
Watermelon Strawberry Banana Smoothie. Add ½ cup of frozen strawberries to blender along with the watermelon and banana.
Watermelon Cucumber Banana Smoothie. Add 1/4 to ½ of a sliced cucumber to blender along with the watermelon and banana. Adjust cucumber to taste.
Watermelon Banana Apple Smoothie. Peel and chop 1 medium apple. If you want a tart flavor, I recommend the Granny Smith or McIntosh variety. If your taste buds lean toward the sweet, I would use Fuji or Gala. Add either 1/2 or whole apple, depending on how much apple flavor you want in your smoothie.
