This Sweet Potato Cranberry Smoothie came to life on one of those chilly, late-winter WFH mornings when I was craving something bright and nourishing. I had a bit of roasted sweet potato in the fridge—not quite enough for lunch—and half a bag of cranberries hiding in the freezer. Not your usual smoothie suspects, but I love experimenting with unexpected flavour combos. Sometimes they flop… but this one? Total win.

The natural sweetness of the sweet potato pairs well with the tartness of the cranberries, and blending them with orange, banana, and warming spices turned it into this thick, creamy, almost dessert-like smoothie that’s genuinely energising. It felt like the kind of breakfast that’s both grounding and uplifting—a little pocket of colour and comfort in the middle of a grey day.

Plus, it's packed with fibre, vitamin C, and antioxidants, so it’s a real win for those mornings when I need a boost but still want something quick and easy, it’s perfect for busy mornings or a quick, energizing snack.

Step By Step Instructions:

Prep the fresh ingredients: Zest and peel the orange, core the apple, and peel a small piece of fresh ginger.

Cook the sweet potato:

Boil (10 min) – Peel, dice, and simmer until fork-tender.
Steam (12 min) – Steam chunks in a basket over boiling water.
Roast (30 min) – Roast peeled chunks at 200°C (400°F) for deep, caramelised flavour.

Let the sweet potato cool completely before blending.

🔄 Ingredient Substitutions

Red Grapes → Swap with blueberries or strawberries for a different berry twist.
Frozen Cranberries → Use frozen raspberries or pomegranate seeds for a similar tartness.
Baobab Powder → Replace with camu camu powder (for a vitamin C boost) or maca powder (for extra energy).
Dates → Substitute with maple syrup or ripe banana for natural sweetness.
Sweet Potato → Try cooked pumpkin or carrot for a similar texture with a slightly different flavor.

🔧 Cooking Tips, Equipment, & Advice

Equipment

A high-speed blender gives the smoothest texture, but a standard blender works fine if you chop ingredients smaller and blend longer.
Store in airtight mason jars if making ahead—shake before serving.

Tips & Tricks

Freeze pre-cooked sweet potato in cubes so it’s smoothie-ready anytime.
Add a few ice cubes if you want it extra cold and frosty.
If using a less powerful blender, grate the ginger before adding.

Shopping Tips

Look for baobab powder in the superfood section or online.
Use organic cranberries if possible to avoid added sugars or preservatives.

🧊 Storage Tips

This smoothie is best enjoyed fresh, but you can store any leftovers in an airtight jar or bottle in the fridge for up to 24 hours. Give it a good shake or stir before drinking, as natural separation is normal. For an extra cold treat, freeze in ice cube trays and blend later with a splash of water or plant milk.

Cooking Sweet Potato:

Boiling Method (Fastest - 10 Minutes)

Peel and dice 100g sweet potato into small cubes for quicker cooking.
Bring a small pot of water to a boil, then add the sweet potato cubes.
Cook for 8-10 minutes until fork-tender.
Drain and let cool completely before using in the smoothie.

Steaming Method (Retains More Nutrients - 12 Minutes)

Peel and chop the sweet potato into small chunks.
Place in a steamer basket over boiling water.
Cover and steam for 10-12 minutes until soft.
Let cool before adding to the blender.

Roasting Method (Best for Deep Flavor - 30 Minutes)

Preheat oven to 200°C (400°F).
Peel and cut the sweet potato into small chunks.
Spread on a baking tray and roast for 25-30 minutes, flipping halfway, until tender.
Let cool before blending.

If you’re into bright, immune-boosting drinks like this smoothie, you’ll love my Tropical Turmeric & Ginger Shots. They’ve got a zesty kick from fresh ginger, the golden glow of turmeric, and a sweet citrusy twist and the best bit? No fancy equipment needed. Just a blender and five minutes.

Blender Recommendation

I always say—use the best blender you can afford. I upgraded to a Vitamix back in 2019, and honestly? Total game changer. Smoothies, sauces, soups… everything blends into the silkiest, velvety dream. If you're blending often (especially fibrous things like oats or chia seeds), that power makes all the difference.

If you're short on space or want something smaller but still strong, I would recommend the Beast Blender or a NutriBullet Pro 1200W(I have this). Both are compact, quick, and great for single servings. Just let your frozen fruit thaw for a minute or two before blending for best results.
