Your choice of sweet potatoes can impact the overall result of the dish. Opt for sweet potatoes that are roughly uniform in size. This way, all your potatoes will bake evenly and you can test if they are done by inserting a knife into the centre of the potato. If the knife slides in effortlessly, with no resistance, that is your signal that the sweet potatoes are perfectly baked.


If you have some leftovers, you can store these for the next day. Place them in an airtight container and store them in the fridge. When you are ready to enjoy them again, reheat them in the oven or microwave.

With a filling of red onion, kale, and cheese

The flavourful filling within the baked sweet potatoes is a delicious combination of red onions, kale, and crumbled cheese with a hint of chilli and garlic. The red onions are caramelised and acquire a deep sweetness that aligns with the baked potato flesh. Their distinct flavour, at the crossroads of savoury and sweet, makes them a perfect pairing for the naturally sweet potatoes. Blanching the kale retains its vibrant colour and crunch. Its slightly bitter undertones cut through the sweetness of the potatoes and onions, bringing a necessary balance to the meal. The finishing touch, a generous sprinkle of crumbled white cheese, adds a creamy, tangy element. It melts slightly against the warm filling, enhancing the overall mouthfeel.

Served in the potato skin for a surprising presentation

Serving the filled sweet potatoes in their own skin lends an element of rustic charm to the presentation. The earthy flavour also adds depth, reinforcing the natural taste of the sweet potatoes. The potato skins, crisp from the oven, add an interesting textural contrast to the soft filling within. The combination of the filled potato skin, contrasting textures, and complementary flavours makes this baked sweet potato dish an inviting and tantalising treat that is as beautiful to look at as it is delicious to eat. Each spoonful delivers a mix of the hearty filling and the crispy skin, making for a pleasant crunch amidst the overall softness.
