Got some leftover sweet potato from meal prep? This Sweet Potato Cranberry Smoothie is the perfect way to use it up!
I created this smoothie during one of those late-winter Work from home mornings and I was craving something nourishing, vibrant, and a bit different from my usual smoothie go-tos. I had leftover roasted sweet potato in the fridge, not quite enough for a lunch or a dinner…. and half a bag of cranberries in the back of the freezer—two ingredients that don’t usually scream “smoothie,” but I love playing with unexpected flavour combos, sometimes they work… sometimes they don’t.
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.
