Let me tell you about the morning that changed my smoothie game forever. I was rushing around the kitchen, trying to pack something nutritious for my daughter’s school lunch, when I spotted those slightly overripe bananas on the counter and a few kiwis that were perfectly soft to the touch. Instead of letting them go to waste, I threw them into my Thermomix with a handful of other ingredients, and what came out was pure magic – a vibrant green kiwi banana smoothie that was both refreshing and creamy, with the perfect balance of sweet and tangy flavors.
This Thermomix kiwi banana smoothie has since become our family’s go-to breakfast drink and afternoon pick-me-up. There’s something so satisfying about watching the Thermomix work its magic, transforming simple ingredients into a silky-smooth, restaurant-quality smoothie in less than a minute. Trust me, once you try this recipe, you’ll understand why it’s earned a permanent spot in our daily routine.

Why This Kiwi Banana Smoothie is Special
What makes this kiwi banana smoothie recipe truly exceptional is the perfect harmony between the tropical sweetness of ripe bananas and the bright, slightly tart flavor of fresh kiwis. The Thermomix does all the heavy lifting here, breaking down those tiny kiwi seeds and banana fibers to create an incredibly smooth texture that’s impossible to achieve with regular blenders.
This smoothie strikes that perfect balance – it’s nutritious enough to serve as a healthy breakfast, refreshing enough for a post-workout drink, and delicious enough that even the pickiest eaters in your family will ask for seconds. The natural sweetness from the bananas means you won’t need to add any refined sugars, making this a guilt-free treat that’s packed with vitamins, fiber, and natural energy.
Difficulty Level: Beginner-friendly
Prep Time: 5 minutes
Total Time: 5 minutes
Serves: 2-3 generous portions
Ingredients You’ll Need
Here’s what you’ll need to create this delicious kiwi banana smoothie in your Thermomix:
- 3 ripe kiwis, peeled and roughly chopped
- 2 medium bananas, peeled and sliced (frozen works great too!)
- 1 cup cold milk (dairy, almond, or oat milk all work beautifully)
- 1/2 cup Greek yogurt (adds incredible creaminess)
- 1 tablespoon honey (optional, adjust to taste)
- 1/2 cup ice cubes (for that perfect chill factor)
- 1 teaspoon fresh lime juice (this is the secret ingredient!)
- 1/4 cup fresh spinach leaves (optional, but trust me on this one)
Serving size: This recipe makes about 3 cups of smoothie, perfect for 2-3 servings depending on your glass size.
Pro tip: When selecting kiwis, look for fruits that give slightly when pressed but aren’t mushy. They should have that perfect sweet-tart balance that makes this smoothie sing. For bananas, slightly overripe ones actually work better – they’re sweeter and blend more easily in the Thermomix.

Step-by-Step Thermomix Instructions
Step 1: Prepare Your Ingredients
Start by peeling and chopping your kiwis into rough pieces – don’t worry about being precise here, as the Thermomix will handle everything beautifully. Slice your bananas and have all your other ingredients measured and ready to go. This is where meal prep lovers can get ahead – you can actually prep fruit portions in freezer bags for grab-and-go smoothie making!
Step 2: Add Ingredients to Your Thermomix Bowl
Place the chopped kiwis and banana slices into your Thermomix bowl first, followed by the Greek yogurt, milk, and lime juice. If you’re feeling adventurous and want to sneak in some extra nutrition (especially great for kids), add those spinach leaves now – I promise you won’t taste them, but you’ll get a beautiful vibrant green color and extra vitamins.
Here’s the secret: Add the lime juice! This tiny addition brightens the entire flavor profile and prevents the bananas from oxidizing, keeping your smoothie looking fresh and vibrant.
Step 3: Initial Blend
Close the lid and blend on Speed 6 for 30 seconds. This initial blend breaks down the fruit and gets everything moving around the bowl. Don’t worry if it doesn’t look perfectly smooth yet – we’re building up to that silky texture gradually.
Step 4: Add Ice and Final Blend
Add your ice cubes through the hole in the Thermomix lid while the machine is running – this prevents the ice from getting stuck at the bottom. Then increase to Speed 8 for another 45-60 seconds until you achieve that perfect, creamy smoothie consistency.
Pro tip: If your smoothie seems too thick, add a splash more milk and blend for another 15 seconds. If it’s too thin, add half a frozen banana or a few more ice cubes and blend again.
Step 5: Taste and Adjust
This is where the magic happens! Give your kiwi banana smoothie a taste and adjust as needed. Too tart? Add a drizzle of honey. Want it more tropical? Add a handful of frozen pineapple chunks and blend again. The beauty of smoothie making is that you can customize it to your exact preferences.
Chef’s Tips and Variations
Storage wisdom: This smoothie is best enjoyed immediately, but you can store it in the refrigerator for up to 24 hours. Just give it a good stir or quick blend before drinking, as natural separation is completely normal.
Make it a smoothie bowl: Pour your thick kiwi banana smoothie into a bowl and top with sliced kiwi, banana coins, granola, coconut flakes, and chia seeds for a Instagram-worthy breakfast that’s as nutritious as it is beautiful.
Protein power-up: Add a scoop of vanilla protein powder for a post-workout boost. The Thermomix handles protein powder beautifully, ensuring no clumps or chalky texture.
Tropical twist: Substitute half the milk with coconut milk and add a handful of frozen mango chunks. You’ll transport yourself straight to a tropical paradise with every sip.
Green goddess version: Don’t be afraid of that spinach! Adding a handful of baby spinach or even half an avocado creates an incredibly creamy texture while boosting the nutritional value. The fruit flavors completely mask any “green” taste.
Make-ahead magic: Prepare smoothie packs by portioning out your fruit and freezing them in individual bags. When you’re ready for your smoothie, just dump the frozen fruit into your Thermomix with the liquid ingredients and blend. It’s like having a healthy fast-food option right in your freezer.
Consistency control: For a thinner smoothie perfect for drinking on-the-go, use more milk and less yogurt. For a thicker smoothie that’s perfect for smoothie bowls, use less liquid and more frozen fruit.
Perfect Pairings and Serving Suggestions
This refreshing kiwi banana smoothie pairs beautifully with whole grain toast topped with almond butter, a handful of nuts, or a homemade granola bar. It’s also fantastic as an afternoon pick-me-up when you’re craving something sweet but want to keep it healthy.
For special occasions, serve it in chilled glasses with a kiwi wheel garnish and a colorful paper straw. Kids absolutely love the vibrant green color, and it’s a fun way to get them excited about eating (or drinking) their fruits and vegetables.
Your New Favorite Morning Ritual
There’s something truly special about starting your day with a homemade kiwi banana smoothie made in your Thermomix. It’s quick enough for busy mornings, nutritious enough to fuel your day, and delicious enough to make you feel like you’re treating yourself to something special.
The best part? This recipe is incredibly forgiving and adaptable. Don’t have Greek yogurt? Regular yogurt works fine. Out of kiwis? Try it with green grapes or even a green apple for a different but equally delicious flavor profile. The Thermomix makes it so easy to experiment and find your perfect combination.
So go ahead, give this easy Thermomix smoothie recipe a try. I have a feeling it’s going to become as much of a staple in your kitchen as it has in mine. Here’s to delicious mornings and the simple joy of a perfectly blended smoothie that tastes like sunshine in a glass!
