1Jab sweet potatoes with a fork and roast in the oven at 200°C (400°F) for 45-60 minutes, or air fry at 190°C (375°F) for 30-40 minutes, flipping halfway.
2While potatoes are cooking, prepare the filling by browning beef mince in a pan with oil.
3Add chopped red onion, garlic, paprika, chilli powder, and Italian mixed herbs to the beef mince.
4Once the beef mince is browned, add tomato paste and chopped spinach.
5Remove the cooked sweet potatoes from the oven and slice them down the middle.
6Use a fork to fluff up the flesh of the sweet potatoes.
7Top the sweet potato halves with the beef mince filling and grated mozzarella cheese.
8Return the stuffed sweet potatoes to the oven until the cheese is golden and crispy.
