Using a small sharp knife, cut the onion in half and peel off the skin, then put each half on a chopping board and cut into slices, keeping the root intact. Then make 2 horizontal cuts one above the other and finally, chop down across the width of the onion. Peel the carrots and cut into dice with the celery. Peel the garlic and use a garlic crusher or grate on the fine side of a box grater.
Heat a frying pan over a medium heat. Add half of the butter and once it is melted. Tip in the onion, carrots, celery and garlic, stirring to combine. Cook for about 5 minutes until softened, stirring occasionally with a wooden spoon.
Add the steak mince to the pan and cook for another 3-4 minutes or until browned, stirring occasionally and breaking up any lumps with a wooden spoon. Stir in the packet mix and then add the water. Bring to a simmer and then cook for 5 minutes until thickened, stirring occasionally. Place in a small ovenproof dish and set aside to allow a skin to form. This will make it easier to spread over the potatoes.
Preheat the oven to 180C / 350F / gas mark 4. Peel the potatoes and cut into dice. Place in a saucepan fitted with a petal steamer and cook over a medium heat for 10-12 minutes or until tender. Tip into a bowl and mash with a potato masher until smooth. Season lightly with salt, if using and add plenty of freshly ground black pepper, then beat in the rest of the butter with the milk. Spoon the mash on top of the mince, starting with dollops around the edges and finishing with the middle. Spread around with a table knife until you have a nice even layer and then bake for 30-40 minutes until bubbling and golden brown.
Meanwhile, trim the ends off the green beans and put in a saucepan fitted with a petal steamer over a medium heat. Cook for 3-4 minutes until tender, then drain and arrange on plates with the Shepherd’s pie to serve.
