We love smoothies at our house. In fact, we have a healthy green smoothie every day. We like expanding our flavor options and this sour apple smoothie is a fun one to have in the mix.

Smoothies are great for breakfast, but they also make a perfect pre or post-workout snack.

Key Ingredients

  • Lemon — We’ll use both the zest and the juice of the lemon.
  • Oats — I used rolled oats for this recipe, but you can substitute instant oats.
  • Chia — We’ll add some ground chia seeds to create a thicker texture. You can use whole chia seeds; I just prefer ground because it creates a smoother finished texture.
  • Syrup — I used maple syrup, but you can substitute agave nectar.
  • Milk — We’ll use almond milk for the best overnight oats! Substitute your favorite plant-based milk.
  • Yogurt — I love adding some plant-based yogurt (plain, unsweetened) for an even more tangy flavor.
  • Protein Powder — I add some vanilla protein powder for increased flavor and nutrients. If your protein powder is not sweetened, you may want to add an extra teaspoon or two of sweetener.
  • Cornstarch — We’ll use cornstarch to thicken the lemon curd topping.
  • Turmeric — A pinch of turmeric makes that lemon curd sunny yellow.
  • Apple — You’ll need one Granny Smith apple
  • Banana — Add sweet flavor with two large bananas.
  • Spinach — You’ll want to use fresh spinach for your smoothie.
  • Protein powder — I prefer using vanilla protein powder for flavor and nutrition.
  • Yogurt — I like using plain vegan yogurt. You can substitute plant-based milk and a bit of apple cider vinegar.
