Peel and grate sweet potato into a bowl. Using paper towel squeeze any excess water out of the grated sweet potato.
Preheat oven to 180c.
In a cup, whisk the egg and add the whisked egg, flour, salt & pepper to the grated sweet potato.
Mix all ingredients together.
Heat frying pan and add extra virgin olive oil. Once heated, using your hands, make small patties and add them to the frying pan.
Lightly fry on each side until brown and then add to a baking tray.
Once all rostis are cooked on both sides, place into the oven for 15 mins to cook the sweet potato through.
While the rostis are in the oven, its the perfect time to cook bacon and eggs.
Recommended serving suggestion; poached eggs, bacon, rocket and salsa (chopped tomato, avocado and fresh basil).
