Ingredients

For the sweet potato:

  • 450 g (16 oz) sweet potato , peeled and sliced
  • 1 teaspoon (1 teaspoon) coconut oil
  • Pinch (Pinch) salt
  • 1/4 teaspoon (1/4 teaspoon) ground cinnamon
  • 1 tablespoon (1 tablespoon) maple syrup to taste (or sub any other sweetener)

For the topping:

  • 75 g (3/4 cup) rolled oats (ensure gluten-free if necessary)
  • 40 g (1/3 cup) pecan nuts , roughly chopped
  • 1/4 teaspoon (1/4 teaspoon) ground cinnamon
  • 3 tablespoons (3 tablespoons) maple syrup (or sub any other sweetener)
  • 1 tablespoon (1 tablespoon) coconut oil

Instructions

  • Preheat the oven to 180 degrees Celsius (350 degrees Fahrenheit)

For the sweet potato:

  • Place the sliced sweet potatoes in a pan and roughly cover with water
  • Bring to the boil, turn down the heat and cook for around 15 minutes until soft enough to gently piece with a fork
  • Drain away the water and add the coconut oil, salt, cinnamon and maple syrup to the cooked sweet potatoes
  • Use a potato masher or a fork to mash the sweet potatoes

For the topping:

  • Mix together all the ingredients in a bowl

To assemble:

  • Place the mashed sweet potatoes in a baking dish - I used a 20.5 cm/8 inch pie dish
  • Sprinkle the topping over the mashed sweet potatoes in the baking dish
  • Bake in the oven for 20 minutes, until top is crispy and golden brown
  • Best when fresh but leftovers keep covered in the fridge for a few days - best reheated in the oven
