Grab your blender and add the frozen strawberries first. This prevents them from hiding under the liquid where they won't blend properly. I learned this the hard way after chunky smoothie disasters. Add the banana next, then the Greek yogurt and milk. The liquid goes in early so the frozen fruit has something to work with.
Pour in the honey, which dissolves way easier when it hits the liquid. Add your chia seeds, cinnamon, nutmeg, and sea salt—yes, really, the salt rounds out all the flavors and you won't taste it. Seriously, this makes a huge difference. Top everything with the ice cubes right before blending.
Blend on high speed for about 45 seconds, or until you don't see any chunks of strawberry floating around. Listen for the sound to change—when it goes from grinding to smooth humming, you're done. Don't over-blend or you'll add too much air and end up with a thick foam instead of a silky smoothie.
Stop and check the consistency by looking through the blender jar. The whole strawberry banana smoothie recipe should pour smoothly but feel thick enough to eat with a spoon if you needed to. If it's too thin, add more ice and blend for another 10 seconds.
Pour immediately into glasses while it's still perfectly cold and smooth. I always do this right after blending because sitting in the blender makes it separate a tiny bit. Use four glasses for normal servings or two if you want seriously thick smoothie bowls.
Top with extras if you're feeling fancy—granola, coconut flakes, or fresh berries all work beautifully. Honestly though, it's perfect plain too, and some mornings I just want to drink it standing at the counter. No judgment here.
Serve right away and watch how fast it disappears. The texture stays best when you drink it immediately, but it keeps in the fridge for about 2 hours if you need to make it ahead. Just give it a quick shake before drinking since the chia seeds settle on the bottom.
