This is a real winter favourite in Pinnock Towers! I have made this a vegetarian one as it’s a recipe that works very well, but you can absolutely use the traditional minced (ground) beef if you like. The sweet potato topping is lower GI than regular potato, plus the bright orange flesh is rich in beta carotene, which is a potent antioxidant.
Preheat the oven to 180°C/350°F/Gas mark 4.
Place the chopped sweet potato in a saucepan, cover with boiling water and simmer until soft. Drain, mash well and set aside.
While the sweet potato is cooking, heat a little oil in a large saucepan, add the onion, garlic, carrots and a good pinch of salt, and sauté until the onion has softened.
Add the lentils, tomatoes, thyme, cinnamon and bouillon powder, and simmer for around 20 minutes, until the tomatoes have reduced right down to create a thick sauce with the lentils.
Transfer to a deep baking dish, top with the mashed sweet potato and bake in the oven for around 20 minutes.
