If it still hasn't browned, then pop the pan (only if it's ovenproof though!) under a hot grill for 5 minutes. Pat it out flat again and continue cooking until really crisp all over. Once the bottom turns golden, carefully flip it over bit by bit and mash it back into itself. If it is, then lower the heat and keep watching it.


Pat it down into a thick pancake shape and keep frying on a medium heat for about 30 minutes, checking it every 5 minutes or so to make sure the bottom isn't burning. Add the potatoes and vegetables and gently mash them up in the pan to give a nice bubble and squeak mixture. Heat a lug of olive oil and a good knob of butter in a large frying pan over a medium heat.If using leftover veg, you can add these directly to the cooked potatoes now. If you managed to get through all of the vegetables you served with your Christmas dinner then just boil the potatoes and raw vegetables together in a large pan of salted, boiling water for 15 to 20 minutes until they are all cooked through.
