This avocado-spinach green smoothie is thick, creamy, and gently sweet, with a squeeze of lime to keep the flavor bright. Frozen banana and Greek yogurt make it satisfying without hiding the fresh spinach, and the avocado gives it a velvety texture that blends smoothly for breakfast or a quick snack.
Ingredients
- 1 medium ripe avocado, about 5 ounces (140 g) of flesh
- 2 cups loosely packed baby spinach, about 60 g
- 1 medium ripe banana, peeled, sliced, and frozen, about 1 cup
- 1 cup (240 ml) milk, dairy or unsweetened plant milk
- 1/2 cup (120 g) plain Greek yogurt
- 1 tablespoon fresh lime juice
- 1 teaspoon honey or maple syrup, optional
- 1/2 cup ice cubes, optional, for a colder or thicker smoothie
- 1 small pinch fine salt, optional
This makes 2 modest servings, or 1 generous breakfast portion. The recipe is easy to scale, but blend in batches if your blender jar is small. Use a ripe avocado that gives slightly when pressed; an underripe one can leave small firm pieces and a grassy, less rounded taste.
Instructions
- Prepare the ingredients. Halve the avocado, remove the pit, and scoop the flesh into a measuring cup or directly into the blender. Slice the banana before freezing if it is not already prepared. Rinse the spinach and shake off excess water. Measure the milk, yogurt, and lime juice so they are ready to add.
- Add the liquid and greens first. Pour the milk into the blender jar, then add the spinach. This order helps the blades catch the leaves instead of letting them sit above the blades. Add the yogurt, lime juice, avocado, frozen banana, and the small pinch of salt if using.
- Blend until completely smooth. Secure the lid and start on a low setting, then increase to high. Blend for about 45 to 60 seconds, or until you no longer see spinach flecks or avocado pieces. If the mixture stalls, stop the blender and use a tamper if your blender has one. Otherwise, switch it off, scrape down the sides with a spatula, and add a tablespoon or two of milk before blending again.
- Adjust the texture. For a thinner smoothie, blend in more milk a tablespoon at a time. For a thicker, colder drink, add the ice and blend again until it is crushed and evenly incorporated. Frozen banana already chills and thickens the mixture, so you may not need ice, especially with a high-powered blender.
- Taste and finish. Taste before adding sweetener because a very ripe banana may be sweet enough. If you want a sweeter drink, blend in the honey or maple syrup. Add a little more lime juice if you prefer a brighter flavor, then pour into two glasses and serve promptly.
Tips
- Choose spinach with a mild flavor. Tender baby spinach blends more easily than mature leaves and usually has a softer taste. Remove thick stems from mature spinach if that is what you have. Two packed cups are not necessary; loosely fill the cups so the greens do not overwhelm the fruit and dairy.
- Use frozen banana for a thick result. Peel and slice ripe bananas, freeze them in a single layer on a tray, and transfer the pieces to a sealed container once firm. Slices are easier to blend than one solid frozen banana. If you only have a fresh banana, use it and add the optional ice, or expect a thinner, less chilled smoothie.
- Start with the listed liquid amount. It is easier to thin a smoothie than to rescue one that has become watery. Blenders vary, and a small jar or less-ripe avocado may need an extra splash of milk. Add it gradually, blending between additions, until the drink moves freely but still coats a spoon.
- Balance the flavor before sweetening. Lime helps cut the richness of avocado and yogurt. A tiny pinch of salt can make the fruit taste fuller without making the smoothie salty. Add sweetener only after tasting, and use a little at a time so the drink stays fresh-tasting rather than dessert-sweet.
Serving Suggestions
Serve the smoothie right after blending, while it is cold and fluffy. It works as a quick breakfast alongside toast, oatmeal, or a hard-boiled egg, or as a filling snack after a walk or workout. For a simple breakfast bowl, reduce the milk to about 3/4 cup, pour the thicker blend into a bowl, and add sliced banana, berries, or a spoonful of granola on top. Eat it with a spoon before the toppings soften.
If you are serving it to guests, divide it into small glasses as a refreshing snack rather than presenting it as a very sweet fruit drink. A thin lime wheel or a few berries make an easy garnish. Avoid adding a large amount of garnish to the blender itself: seeds, nuts, or granola are better sprinkled on top, where they keep their texture and do not make the smoothie gritty.
Variations
Make it dairy-free: Replace the milk with unsweetened almond, oat, or soy milk, and use a dairy-free plain yogurt or omit the yogurt. Without yogurt, the smoothie will be a little less tangy and rich; add a few extra avocado pieces or a spoonful of nut butter if you want more body. Check flavored plant milks before adding honey, since they may already be sweetened.
Add a gentle tropical note: Replace half the banana with 1/2 cup frozen pineapple or mango. Keep the lime juice, which complements those fruits and keeps the drink tasting lively. If you use a sweeter fruit blend, taste before adding any honey or maple syrup.
Make it more substantial: Blend in 1 tablespoon chia seeds or 1 tablespoon ground flaxseed. The seeds thicken the smoothie as it stands, so add another splash of milk if needed and drink it soon after blending for the best texture. You can also add 1 tablespoon unsweetened nut butter for a richer flavor; start with a small amount because it will make the avocado taste less prominent.
Use other greens sparingly: You can replace up to half of the spinach with mild kale leaves, with the tough stems removed. Kale has a stronger flavor and takes longer to blend completely, so use a powerful blender and blend until no fibrous pieces remain. For the closest match to the original recipe, stick with spinach.
Storage and Reheating
This smoothie is best immediately after blending, when the banana is cold and the texture is light. If you need to make it ahead, pour it into a clean, airtight jar, fill the jar nearly to the top to limit air exposure, and refrigerate it promptly. It will keep for up to 24 hours, but it may darken slightly and separate as it sits. Lime juice slows browning but cannot prevent all color and texture changes.
Before drinking a refrigerated portion, shake the closed jar vigorously or stir it well. If it has thickened, loosen it with a tablespoon or two of milk. Discard it if it has been left at room temperature for more than 2 hours, or if it smells or looks spoiled. Do not heat this smoothie: warming changes its fresh flavor and makes the creamy texture unpleasant. For longer storage, freeze portions in freezer-safe containers for up to 2 months. Thaw overnight in the refrigerator, then shake or briefly reblend; the texture may be less smooth than a freshly made smoothie.
Frequently Asked Questions
Can I taste the spinach? You may notice a mild green flavor, but ripe banana, yogurt, and lime keep it balanced. Baby spinach is especially gentle. If you are new to green smoothies, begin with 1 1/2 cups spinach and increase it to 2 cups next time. Avoid adding extra greens before tasting, since they can make the drink more vegetal and less sweet.
Do I need to peel the avocado or remove its pit? Yes. Cut around the avocado lengthwise, twist the halves apart, remove the pit carefully, and scoop out the flesh with a spoon. The skin and pit are not ingredients for this smoothie. If the avocado is difficult to scoop because it is firm, it is probably not ripe enough for the creamiest result.
Can I make this without a high-powered blender? Yes, though you may need to blend in stages. Let frozen banana pieces sit for a few minutes, blend the spinach with the milk first until finely chopped, then add the remaining ingredients. Stop and scrape down the jar as needed, and avoid filling the blender past its recommended capacity. A less powerful blender may leave a few tiny spinach flecks, but the drink should still taste good.
How can I make the smoothie less thick? Blend in cold milk one tablespoon at a time until it reaches the consistency you like. If you have not added the ice yet, leave it out. A very thick blend usually comes from a large frozen banana, a small amount of liquid, or extra-thick yogurt; a little extra milk will correct it without changing the flavor much.
Can I prepare smoothie packs in advance? You can portion the spinach, sliced banana, and avocado into freezer-safe bags and freeze them for up to 2 months. For best color, add a little lime juice to the avocado and press excess air from the bag. When ready to blend, add the frozen ingredients to the blender with the milk and yogurt; do not freeze the milk or yogurt in the pack. Blend from frozen, adding extra milk if the mixture is too thick.
