- Peel the potatoes and cut into even-sized pieces. Put into a saucepan and cover with cold water, cover and bring to the boil. Reduce the heat and simmer for about 20 minutes or until soft.
- While the potatoes are cooking finely chop the onion and add to the potatoes.
- Drain the potatoes well and return to the pan. Add the butter with some of the milk and HALF of the cheese. Mash well.
- Put the potatoes in the oven proof dish and sprinkle the chopped bacon on top. Add the remaining cheese and place on a baking tray.
- Bake for about 20-30 minutes or until the top is golden brown.
- While your dish is baking have a go at making a tomato lily for decoration.
Lovely served with baked beans or just on its own. Enjoy!
