How to make green smoothies taste good. Then we’ll need a creamy base. They’re a natural thickener. Green smoothies are simply blended mixtures of whole foods that include greens (like spinach, kale, and collard) or other nutrient-dense veggies, and they may or may not contain other ingredients like fruit or nuts blended in. This can be especially helpful if you’re not eating your smoothie right away. A smoothie for one typically takes about 1 1/2 to 2 cups of liquid. Adding in a tablespoon of chia seeds will add healthy fats that also make your smoothie thicker! I usually use chopped and frozen bananas. The secret to ultra-smooth green smoothies is in blending the liquids and greens together first, then adding in the rest of your ingredients. This step prevents having chunky bits of spinach or kale floating around your smoothie! The amount of liquid you use for your smoothie depends on how large it is, and how smooth or thick you like it. Don’t let the name mislead you—green smoothies don’t necessarily come out looking green! You can use water, coconut water, or my personal favourite, homemade nut milk. After just a few minutes, the chia will start to absorb liquid from the smoothie, and the seeds will expand, creating a thicker texture.
