Vegetables can make smoothies taste better when you choose the right ones and pair them properly. Some vegetables add natural sweetness, some bring freshness, some create a thicker texture, and others give colour without overpowering the drink. The trick is not to throw everything into a blender and hope for the best. It is to match each vegetable with fruit, yoghurt, milk, spices or citrus that balance its flavour.
A good vegetable smoothie should still taste like something you want to drink. Spinach works because it is mild. Beetroot works because it adds earthy sweetness and deep colour. Carrot brings natural sweetness. Pumpkin makes a smoothie creamy. Kale can work well, but it needs stronger fruit to soften its green flavour.
For UK readers, it is also worth keeping health claims in proportion. The NHS says that fruit juice, vegetable juice and smoothies count as a maximum of one portion of your 5 A Day, and recommends limiting them to one small 150ml glass a day. The British Dietetic Association also notes that free sugars and acids in juices and smoothies can contribute to tooth decay, so smoothies are best enjoyed with meals rather than sipped constantly through the day.
Quick guide: the best vegetables for smoothies
| Vegetable | What it adds | Best pairings | How much to use |
|---|---|---|---|
| Spinach | Mild green flavour and colour | Banana, mango, pineapple, apple, berries | 1 small handful |
| Beetroot | Earthy sweetness and deep red colour | Berries, apple, orange, ginger, cocoa | ¼ to ½ cooked beetroot |
| Kale | Stronger green flavour | Pineapple, mango, lemon, apple, grapes | 1 small handful, stalks removed |
| Carrot | Natural sweetness and orange colour | Orange, mango, ginger, cinnamon, yoghurt | 1 small grated carrot or ½ cooked carrot |
| Pumpkin | Creaminess and gentle sweetness | Banana, yoghurt, cinnamon, nutmeg, ginger | 2 to 4 tablespoons pumpkin purée |

| Courgette | Body without much flavour | Banana, berries, cocoa, peanut butter | ½ small courgette, fresh or frozen |
1. Spinach
Spinach is one of the easiest vegetables to add to smoothies because its flavour is mild. When blended with sweet fruit such as banana, mango, pineapple or apple, the spinach usually fades into the background while still giving the smoothie a fresh green colour.
Start with one small handful of fresh spinach or a small portion of frozen spinach. Too much can make the smoothie taste grassy, especially if you are not used to green smoothies. For a simple combination, blend spinach with banana, mango, Greek yoghurt and a splash of milk or unsweetened plant-based drink.
Spinach works best when you want a green smoothie that still tastes mainly of fruit. It is a good starting point for anyone trying vegetable smoothies for the first time.
2. Beetroot
Beetroot adds deep colour, gentle sweetness and an earthy flavour. In the UK, cooked vacuum-packed beetroot is easy to find in supermarkets and is usually softer and sweeter than raw beetroot, making it a convenient smoothie ingredient.
Use ¼ to ½ cooked beetroot per smoothie. Beetroot pairs especially well with berries, apple, orange, ginger and lemon. A berry and beetroot smoothie works because the sharpness of raspberries or blackberries balances the beetroot’s earthiness.
If you are new to beetroot smoothies, start small. Too much beetroot can dominate the drink. A good beginner blend is cooked beetroot, frozen mixed berries, apple, lemon juice and a spoonful of yoghurt.
3. Kale
Kale has a stronger flavour than spinach, so it needs better balancing. The leaves can taste bitter or cabbage-like if you blend them with mild ingredients only. To make kale work, pair it with bright, sweet and acidic flavours such as pineapple, mango, apple, lemon or green grapes.
Remove the tough stalks before blending, as they can make the smoothie fibrous. Use one small handful of chopped kale, then add enough fruit to soften the flavour. A good combination is kale, pineapple, banana, lemon juice and water or coconut water.
Kale is best for people who already enjoy green smoothies or do not mind a more noticeable vegetable taste. For a gentler version, mix half kale and half spinach.
4. Carrot
Carrot brings natural sweetness, colour and a clean flavour that works well in breakfast smoothies. It is especially good with orange, mango, ginger, cinnamon and yoghurt. The result can taste fresh and bright, or warm and dessert-like depending on the ingredients you use.
Raw carrot can be hard on some blenders, so grate it first or use lightly cooked carrot for a smoother texture. One small grated carrot is usually enough. For a carrot-cake-style smoothie, blend carrot with banana, yoghurt, cinnamon, ginger and a small handful of oats.
Carrot is a strong choice if you want a smoothie that tastes sweet without relying only on fruit juice.
5. Pumpkin
Pumpkin is excellent in smoothies because it adds body, creaminess and a gentle sweetness. It works best as pumpkin purée rather than raw pumpkin. You can use homemade cooked pumpkin purée or tinned pumpkin purée, as long as it is plain and not pre-sweetened pie filling.
Use 2 to 4 tablespoons of pumpkin purée per smoothie. It pairs well with banana, yoghurt, milk, cinnamon, nutmeg and ginger. A pumpkin smoothie can feel richer than a standard fruit smoothie, especially if you add oats or Greek yoghurt.
For an autumn-style smoothie, blend pumpkin purée with banana, yoghurt, milk, cinnamon and a little fresh ginger. It gives the flavour of pumpkin pie without needing to turn the drink into a dessert.
6. Cucumber
Cucumber is useful when a smoothie feels too heavy. It adds water, freshness and a clean taste rather than sweetness. It works especially well in lighter green smoothies with mint, lime, apple, spinach or melon.
Use ¼ to ½ cucumber, depending on how fresh and watery you want the smoothie to be. Leave the skin on if you like a greener taste, or peel it for a softer flavour. Cucumber is best in smoothies that are designed to be refreshing rather than creamy.
A simple cucumber blend is cucumber, spinach, apple, lime, mint and cold water. It is crisp, light and useful when you want something less rich than a banana-based smoothie.
7. Courgette
Courgette is one of the most underrated vegetables for smoothies. It has a mild flavour, blends easily and adds body without making the drink taste strongly of vegetables. Frozen courgette is especially useful because it thickens the smoothie in the same way frozen banana does, but with less sweetness.
Use half a small courgette, chopped before blending. It works well with berries, banana, cocoa, peanut butter, yoghurt and oats. If you want a thicker smoothie but do not want it too sweet, courgette is a useful option.
For a chocolate-style smoothie, blend frozen courgette with banana, cocoa powder, milk and a spoonful of peanut butter. The courgette adds texture but mostly disappears into the background.
How to make vegetable smoothies taste better
The easiest way to improve a vegetable smoothie is to balance the vegetable with the right flavour partner. Green vegetables usually need sweetness and acidity. Earthy vegetables need sharp fruit or citrus. Creamy vegetables work well with yoghurt, oats, banana and warm spices.
- For mild green smoothies: use spinach with banana, mango or pineapple.
- For earthy smoothies: use beetroot with berries, orange or ginger.
- For creamy smoothies: use pumpkin or courgette with banana, yoghurt or oats.
- For fresh smoothies: use cucumber with mint, lime, apple or melon.
- For stronger greens: use kale with pineapple, lemon or mango.
Texture matters too. If your smoothie tastes fine but feels gritty, blend it for longer, remove tough stems, grate hard vegetables before blending, or use cooked vegetables such as cooked carrot, cooked beetroot or pumpkin purée.
Are vegetable smoothies healthy?
Vegetable smoothies can be a useful way to add variety to your diet, but they should not replace eating whole vegetables. Whole vegetables usually take longer to eat and can be more satisfying. Smoothies are also easy to drink quickly, especially when they contain a lot of fruit or juice.
According to the NHS 5 A Day portion guidance, fruit juice, vegetable juice and smoothies can only count as a maximum of one portion of your 5 A Day, even if you drink more than 150ml. The NHS also advises keeping juice and smoothies to mealtimes because blending and juicing can make sugars more available to the teeth.
To keep a smoothie more balanced, use whole or blended fruit instead of large amounts of juice, include vegetables, and consider adding yoghurt, milk, oats, seeds or nut butter for texture and staying power. The British Heart Foundation also recommends being careful with shop-bought smoothies, which may contain more fruit juice or added sugars than homemade versions.
Best vegetable smoothie combinations to try
- Spinach, mango and banana: mild, sweet and beginner-friendly.
- Beetroot, berries and ginger: earthy, sharp and colourful.
- Kale, pineapple and lemon: green, bright and fresh.
- Carrot, orange and cinnamon: naturally sweet with a warm finish.
- Pumpkin, banana and yoghurt: creamy, smooth and gently spiced.
- Cucumber, mint and lime: light, cooling and refreshing.
- Courgette, cocoa and peanut butter: thick, mild and dessert-like.
Final thoughts
The best vegetables for smoothies are the ones that improve flavour or texture rather than simply adding “healthiness” for its own sake. Spinach is the easiest green to hide. Beetroot brings colour and earthy sweetness. Kale needs bold fruit. Carrot adds clean sweetness. Pumpkin creates creaminess. Cucumber keeps things fresh. Courgette gives body without taking over.
Start with small amounts, use fruit or citrus to balance stronger flavours, and treat the smoothie as one part of your diet rather than a shortcut to health. Done well, vegetable smoothies can be colourful, practical and genuinely enjoyable.
