1. Peel the skins off the potatoes and boil until soft to mash.
2. Preheat an oven to 400 degrees F.
3. In a large, oven safe frying pan, over medium heat, fry the ground been until about 70% cooked through. As the beef is frying, add the bay leaf to get it started. Remember to take out the bay leaf prior to adding on the mashed potato topping.
4. Add the carrots, onions, and garlic. Cook until soft.
5. In a mixing bowl mash the potatoes, adding the milk and butter. If you want the potatoes really smooth use an electric mixer. Add more liquid as needed. Salt and pepper to taste. Transfer the mashed potatoes to the top of the filling. Get creative here!
6. Bake in the centre of the oven for around 30-40 minutes or until the potatoes on top are golden brown.
7. Garnish with green onions or chives.
