- Easy to customize: Swap the fruit, milk, or add-ins based on what you have. It’s versatile and forgiving.
- Quick to make and clean up: One blender, a few ingredients, and you’re done in five minutes.
What You’ll Need
- 1 ripe avocado (pitted and peeled)
- 2 loosely packed cups fresh spinach (rinsed and dried)
- 1 small ripe banana (frozen if you prefer a colder, thicker smoothie; or 2 pitted Medjool dates for a banana-free version)
- 1 cup unsweetened almond milk (or oat milk, coconut milk, or dairy milk)
- 1/2 cup cold water (adjust to thin as needed)
- Juice of 1/2 lemon or 1 small lime (about 1–2 tablespoons, to taste)
- 1 tablespoon chia seeds (or ground flaxseed)
- 1/2 teaspoon pure vanilla extract (optional, for a hint of warmth)
- Small pinch of sea salt (optional, enhances flavor)
- Ice cubes (4–6, optional, for extra chill and body)
Instructions

- Prep the produce: Pit and peel the avocado.
Rinse the spinach and pat dry. If using dates, make sure they’re pitted. If using a frozen banana, break it into chunks.
- Layer the blender: Add almond milk and water first, then spinach, avocado, banana or dates, lemon juice, chia seeds, vanilla, and a small pinch of salt.
Top with ice if using.
- Blend until smooth: Start on low, then increase to high for 30–60 seconds, until the texture is silky. Scrape down the sides if needed and blend again.
- Taste and adjust: Add more lemon for brightness, a splash of milk or water to thin, or an extra ice cube for thickness. If you want it sweeter, add half a date or a drizzle of honey.
- Serve immediately: Pour into a chilled glass.
For a little crunch, sprinkle extra chia seeds on top.
Storage Instructions
- Short-term: Refrigerate in a sealed jar for up to 24 hours. Stir or shake before drinking, as natural separation is normal.
- Make-ahead: Prep smoothie packs by freezing spinach, banana chunks, and avocado in portions. In the morning, add liquids, lemon, and seeds, then blend.
- Prevent browning: The lemon helps, but for best color and taste, enjoy within the same day.

Benefits of This Recipe
- Gentle on digestion: Avocado and spinach are easy to digest and provide fiber to keep things moving comfortably.
- Healthy fats for energy: Avocado’s monounsaturated fats help you feel full and support steady energy without a sugar crash.
- Hydration and electrolytes: Spinach and citrus add potassium and magnesium, while the liquid base keeps you hydrated.
- Antioxidant support: Vitamins C and E, plus plant compounds in spinach, help protect against everyday oxidative stress.
- Blood sugar friendly (with smart swaps): Using dates in moderation or a small banana, plus fiber and fat, can help maintain steadier blood sugar.
Pitfalls to Watch Out For
- Overripe avocado bitterness: If the avocado tastes bitter or smells off, skip it.
Use one that’s ripe but not mushy or brown inside.
- Too thick or too thin: If it’s too dense, add water or milk a little at a time. If it’s watery, blend in more ice, spinach, or a few extra avocado slices.
- Too sour or bland: Lemon can overpower; start with less and add to taste. Conversely, a pinch of salt and a touch of vanilla can lift flat flavors.
- Not cold enough: If you like a frosty smoothie, use frozen banana and a handful of ice.
Warm smoothies can taste dull.
- Seed texture: Whole chia seeds can thicken over time. If texture bothers you, use ground chia or flax, or drink right away.
Alternatives
- No banana: Use 2 Medjool dates or half a pear. For less sweetness, try cucumber for freshness and fewer sugars.
- Dairy-free options: Almond milk and oat milk both work well.
Coconut milk (light) adds a gentle tropical note and extra creaminess.
- Protein boost: Add 10–20 grams of unflavored or vanilla protein powder, Greek yogurt, or silken tofu. You may need a bit more liquid.
- Greens swap: Baby kale or a handful of romaine can replace spinach. If using kale, blend longer for smoothness.
- Citrus swap: Lime is tangier; orange adds sweetness.
Start with a small amount and adjust.
- Superfood add-ins: A teaspoon of spirulina, a nub of fresh ginger, or a tablespoon of hemp seeds can change the flavor and nutrient profile.
FAQ
Can I make this smoothie without a high-speed blender?
Yes. Blend liquids and spinach first until very smooth, then add the remaining ingredients. You may need a bit more blending time and liquid for a silky finish.
Is this smoothie good for weight management?
It can be.
The combination of fiber, healthy fats, and protein add-ins helps with satiety. Watch portion size and sweeteners, and consider using half an avocado if you’re keeping calories lower.
What if I don’t like the taste of spinach?
Use baby spinach for the mildest flavor, and lean on lemon or lime to brighten. You can also mix half spinach with romaine or cucumber for a lighter green taste.
Can I add sweeteners?
If you need more sweetness, try a small date, a drizzle of honey, or a splash of orange juice.
Add gradually so you don’t lose the refreshing balance.
How can I make it higher in protein?
Add a scoop of protein powder, 1/2 cup Greek yogurt, or 3 tablespoons hemp seeds. Adjust liquid to keep the texture creamy, not paste-like.
Is it safe to drink this every day?
For most people, yes. It’s a nutrient-dense blend of whole foods.
If you take certain medications or have kidney issues, check with your healthcare provider about high-potassium foods and leafy greens.
Can I use frozen spinach?
You can. Thaw slightly or blend longer. Frozen spinach can have a stronger flavor, so balance with extra citrus if needed.
Will the avocado make it brown?
A little oxidation can happen over time, but lemon helps.
Drink fresh for the best color and taste, or store in an airtight jar filled to the top to minimize air exposure.
