This green detox smoothie recipe is a crisp, creamy way to bring spinach, apple, cucumber, and avocado together in one glass. The apple and coconut water keep the flavor bright, lemon adds a little tartness, and chia seeds give the mixture some body. Despite its familiar “detox” name, this is simply a fruit-and-vegetable smoothie—not a cleansing treatment. It takes about ten minutes to make and serves two. Use cold ingredients and pour it as soon as you finish blending for the freshest flavor and color.

- Quick to prepare: A short produce-prep session and one blender are all you need for two glasses.
Ingredients
Measure everything before turning on the blender. A tart green apple gives the drink its lively edge; if yours is especially sour, you can decide whether to sweeten the finished mixture after tasting it.
- 1 cup fresh spinach, loosely packed and rinsed
- 1/2 ripe avocado, peeled and pitted
- 1/2 cucumber, washed and roughly chopped
- 1 green apple, cored and roughly chopped
- 1 tablespoon chia seeds
- Juice of 1/2 lemon
- 1 cup coconut water, preferably chilled
- Optional: 1–2 teaspoons honey, to taste
Leave the apple peel on if you like; it blends well in a high-speed blender. If your blender is less powerful, cut the apple and cucumber into smaller pieces. Choose an avocado that yields gently when pressed, since an underripe one can leave small pieces in the drink. The coconut water should be plain rather than flavored so you can control the sweetness yourself.
Step-by-Step Instructions
Set out two glasses before you begin. The smoothie is best right after blending, when its texture is light and the apple still tastes especially fresh.
1. Prep the Produce
Rinse the spinach well and shake off excess water. Wash the cucumber and apple, then core the apple and cut both into rough chunks. Halve and pit the avocado, and scoop out the flesh from one half. Squeeze half a lemon, removing any seeds. You do not need uniform knife cuts, but smaller pieces will help a standard blender catch everything evenly. If you are using a waxed cucumber or dislike its skin, peel it first; otherwise, the peel can stay on.
2. Load the Blender
Pour the coconut water and lemon juice into the blender jug first. Add the spinach, cucumber, apple, avocado, and chia seeds. Putting liquid at the bottom helps the blades start moving without leaving dry ingredients stuck against the sides. Hold back the honey for now. It is much easier to add a touch of sweetness after tasting than to fix a smoothie that is sweeter than you wanted. Secure the lid firmly before switching on the blender.
3. Blend Until Smooth
Start at a low speed, then increase to high and blend for about 30–60 seconds, or until there are no obvious spinach or apple pieces. Stop the machine before scraping down the sides if anything clings to the jug. A thick smoothie may need another small splash of coconut water; add it one tablespoon at a time and blend briefly again. The avocado makes the texture creamy, while the chia seeds may continue to thicken it as the smoothie stands. Aim for a pourable consistency rather than trying to make it thin all at once.
4. Taste, Adjust, and Serve
Take a small taste. If you want a sweeter drink, add 1 teaspoon of honey, blend for a few seconds, and taste again before adding a second teaspoon. For more tartness, squeeze in a little extra lemon; for a looser texture, add a splash of cold coconut water. Divide between two glasses and serve immediately. If you prefer a colder drink, start with chilled produce or add a few ice cubes during the final blend. Give each glass a quick stir if it has been sitting on the counter for a few minutes.
Substitutions & Variations
Plain cold water can replace coconut water, though the result will taste a little less sweet. A ripe pear can stand in for the green apple if you want a softer fruit flavor; core it and use about the same amount. Baby spinach is convenient because its leaves blend quickly. If you only have frozen spinach, thaw it and squeeze out excess water before measuring, then begin with a little less and adjust to taste.
For a plant-based version, skip the optional honey or use a small amount of maple syrup. If you like a thinner smoothie, add liquid gradually so the flavor does not become diluted. You can also freeze the apple chunks ahead of time for a frostier texture, but avoid freezing the whole finished mixture in a glass: it expands and may be difficult to stir.

What to Serve With
For breakfast, pair a glass with toast and an egg, a bowl of oatmeal, or yogurt with a spoonful of nuts. Each option adds something to chew alongside the drink and makes the meal feel more complete. If you are serving it as an afternoon refreshment, a handful of crackers or a small sandwich works just as well. Keep the smoothie cold and bring it to the table only when you are ready to drink it.
If you are planning a few different breakfasts for the week, try the blueberry oat smoothie on another morning for a fruit-and-oat variation. This green version is lighter in texture and more cucumber-forward, so the two recipes offer different flavors without changing your blender routine.
Frequently Asked Questions
Can I make this smoothie ahead of time?
You can refrigerate it in a covered container for up to one day, but it tastes best just after blending. Separation and a change in color are normal as it stands. Stir or shake it well before serving, and keep it chilled rather than leaving it on the counter. For the freshest result, prep and refrigerate the washed produce separately, then blend when you are ready.
Do I need to peel the green apple or cucumber?
No. Wash both thoroughly, core the apple, and chop them into pieces your blender can handle. The peels add flecks of color and texture. If you prefer an especially smooth drink or use a lower-powered blender, peeling them is a simple option. You can also blend a little longer, pausing to scrape down the sides safely with the machine off.
What if the smoothie is too thick or too tart?
For thickness, add cold coconut water one tablespoon at a time and blend briefly between additions. For tartness, taste first, then add a little of the optional honey or another sweetener you enjoy. A ripe apple will usually need less sweetening than a very sharp one. Make small adjustments so the spinach, cucumber, and lemon still taste balanced.
