Peel the potatoes and cut them into large cubes. Put them in the saucepan.
Cook the potatoes
Cover the potatoes with cold water, add a pinch of salt and bring to a boil. Cook for 20 minutes over medium heat.
Cook the onion
Finely chop the onion. Cook it in the skillet with a little butter over low heat until translucent.
Tip · If the onion starts to stick, add a tablespoon of hot water to loosen the browned bits.
Cook the ground beef
Add the ground beef to the skillet with the onion. Brown it, stirring so it doesn't stick. Season lightly with salt and pepper.
Mash the potatoes
Drain the cooked potatoes in the colander. Mash them with a fork, adding the warm milk and half of the butter. Season with salt and pepper.
Assemble the pie
Preheat the oven to 180 °C. In a gratin dish, spread out the ground beef, then cover it with the mashed potatoes. Dot with the rest of the butter.
Tip · For a crispier top, slide the dish under the broiler for 2 minutes, keeping an eye on it.
Bake until golden
Bake the dish for 15 minutes to brown the top. Serve hot.
