Table of contents
Drinkable breakfasts/snacks can really come in handy, you can drink smoothies like this sour apple smoothie in the car, while getting ready in the morning, and many other places.
It is a lighter breakfast/snack, so it's great for when you're not very hungry.
Not only are smoothies great to go, but they just take a couple minutes to assemble. For this sour apple smoothie, you'll need to measure out yogurt, chop an apple, and blend it all up, and you're ready to move to your next task.
Also, I've been hesitant to try green smoothies/drinks because they've been completely taken over by diet culture. But in truth, with a good combination of ingredients, they can be tasty.
So here's a green smoothie recipe without diet talk.
Ingredients
Scroll down to the sour apple smoothie recipe card for the amounts of each ingredient, but here's a quick visual + description of what's in this recipe.
- Plain Yogurt: This is essential to making your smoothie creamy, but it also adds in protein, and maybe fat to make your sour apple smoothie more filling and satisfying. Plain yogurt adds to the tart flavor in this sour apple smoothie.
- Granny Smith Apple: Apples are great in smoothies, they add a nice flavor, but make sure to add yogurt or something creamy for a creamy smoothie. Leave the peel for extra nutrients and flavor in your sour apple smoothie.
- Spinach: Spinach is usually a secret weapon in smoothies. Fresh or frozen spinach does a great job blending the smoothie flavors together. I don't have any scientific evidence of this, but it keeps some of the fruits/veggies from tasting too bitter.
- Frozen Ripe Banana: A little frozen banana goes a long way. It adds sweetness, makes your smoothie creamy, and is delicious. If you like a less tart sour apple smoothie, add a full ½ frozen ripe banana.
- Ground Flaxseed: Or chia seed works. I like adding either of these to smoothies for a bit of extra fiber. It doesn't change the flavor, and helps thicken up smoothies just a bit.
- Water: I just used water to blend it up, but you could use orange or apple juice, milk, or coconut water. Water and orange juice would probably keep the smoothie the most tart. Add more if you like a thinner smoothie.
- Lemon Juice: Adding in extra tart flavors to your sour apple smoothie.
Instructions
Scroll down to the sour apple smoothie recipe card for more detailed instructions. Here's a quick overview + photos to see how to make this recipe in general.
1. Add all ingredients to a blender jar: yogurt, chopped granny smith apple, spinach, frozen ripe banana, ground flaxseed, water, and lemon juice. Add yogurt first as it will help your smoothie blend more easily.
2. Blend until smooth. Enjoy your sour apple smoothie immediately.
Storage Tips
Smoothies don't usually store well. If you don't mind it getting more liquid-y and separate, that's fine. Just store in the fridge for a few days.
You could also pour leftover sour apple smoothie into an ice tray and freeze individual ice cubes. Add these to a blender to make another smoothie with more yogurt and liquid for a more mild flavored smoothie.
Substitutions/Tips
- This sour apple smoothie will still be good without the frozen banana, the texture might be less smooth, but it will work. Also, if it'is too tart, you can add ½ whole frozen ripe banana, or some honey or sugar too.
- I like to add ground flaxseed to my smoothies, but it's not essential. You can substitute it for chia seeds if you have those. They're great add-ins to thicken up your smoothie a bit, without changing the flavor much.
- You'll need to add some liquid to get a smoothie texture, I used water to get a nice tart flavor, but orange or apple juice, milk, coconut water, etc would also be good. Start with ⅓ cup and add more if you like a thinner smoothie texture.
- Other great add-ins: You can add cashews, english cucumber, and/or protein powder to your sour apple smoothie.
FAQ
There's a non-food version and smoothie smoothie version. The smoothie smoothie version has a a variety of ingredients like a tart apple, plain yogurt, lemon juice, spinach, and liquids to make a tart smoothie.
Apples are delicious in smoothies, especially tart apples. The only thing is that the texture of an apple smoothie can be somewhat gritty. A frozen ripe banana or yogurt will smooth it out.
Add tart ingredients like a tart apple, lemon juice, and plain yogurt. Also, maybe add a bit less sweet ingredients like banana that may cut down on the sour flavors if you like them.
What to do with leftover ingredients
When you're cooking for one, you often have leftover produce, cans of whatever ingredient, etc. Here are a couple ideas on how to use up the leftover ingredients. It'll help you save money by wasting fewer ingredients.
- Frozen Ripe Banana: Spinach Apple Banana Smoothie, Strawberry Banana Smoothie, Strawberry Banana Milkshake
- Spinach: Lentil Spinach Curry, Thai Inspired Beef Bowl, and Spinach Strawberry Salad, Pineapple Cucumber Smoothie.
- Ground Flaxseed: Baked Oats for One and Apple Pie Overnight Oats.
- Plain Yogurt: the smoothies listed above, or Peanut Butter Yogurt Dip, and Overnight Oats with Yogurt.
