Things I have been cooking lately #140: Sweet potato cottage pie

As the weather gets colder and the wind blows harder, my craving for comfort food just keeps increasing… and what could be more comforting than cottage pie. I have added a bit of a twist by mixing the traditional mashed potato topping with some sweet potatoes. It gives it depth of flavour and an extra little healthy boost.


Sweet potato cottage pie

500g extra lean beef mince
1 onion, finely chopped
2 large carrots, sliced
A large splash of Worcestershire sauce
2 tablespoons of tomato puree
500ml beef stock
300g potatoes, peeled and cut into chunks
600g sweet potatoes, peeled and cut into chunks
3 tablespoons of milk
85g butter
80g frozen peas
50g cheese
Salt and pepper

Fry the onions and carrots in a little vegetable oil over a medium heat. When they have softened, add the mince, turn up the heat and fry for a couple of minutes. Stirring continuously until it has browned. Add Worcestershire sauce and tomato paste and cook for 3 or 4 more minutes. Add stock, turn down the heat and simmer for 20 minutes. After 20 minutes, remove the lid, stir and continue to simmer for a further 20 minutes. Add salt and pepper to taste.

In the meantime turn on the oven to 180C and make the mash. Boil both types of potatoes in salted water for about 10 minutes. Drain, add the milk and butter and squash with a potato masher.

Remove the mince mixture from the heat and pour into large rectangular baking dish, add the peas. Make sure it is even spread across the dish. Cover with mash. “Riffle” with a fork, top with cheese and bake for about 20 minutes in the oven.

Serves 4 – 6


  1. YUMMY!!!! ❤

    I am a HUGE fan of cottage pie – it is one of my all time favourite foods, and I am dying to try this out. However, when pitching the idea to my fiancé, it was shot down so fast xD He doesn't like sweet potatoes because he "doesn't know anything about them" and he is sure that "I can change that" but he is not willing to start here. I will have to ease him into this hahahaha.

      Mr O used to be like that about foods he hadn’t tasted before but I have been feeding him all kinds of weird stuff and he’s learned to trust me. Hopefully in time your fiance will open his palate to new adventures.

      1. xD I started up this cottage pie argument the other day. He said alright, I must do what I must, I am the cook, he is not, and doesn’t really know how things come together. So maybe this weekend I will try it out 😀

  2. Yum! Def making this soon

    Mmmmm, mash! It really is mash season, with the king of all mashes: Christmas dinner mash, only 11 days away 🙂 x

    1. abbiosbiston

      I never get tired of mash. It’s the most comforting of comfort foods.

  6. […] repay Grace’s generosity I invited her and Kevin round to catch up and enjoy Abbi’s sweet potato cottage pie (so deceptively easy the last time I made it) and promptly risked all our lives by using outdated […]
