Minced Beef in Gravy

How to make it

1. Peel the potatoes and cut them into rough, evenly sized pieces. Put them in a pot with cold water so the water just covers them, and salt the water well — salted water seasons the potatoes from the inside while they cook, so they don't have to be seasoned from the surface alone. ⏱ 10 min
2. Bring the potatoes to a boil and cook them, covered, for 18-20 minutes, until a fork slides through with no resistance and the edges have begun to crumble. ⏱ 20 min · passive
3. Melt the butter for the millionbøf in a large, heavy-bottomed skillet over high heat until it stops foaming. Add the ground beef and cook for 6-8 minutes, breaking it apart with a spoon, until the liquid has cooked off and the meat is browned and slightly crisp at the edges.
   Chef's tip Ground beef releases water first; while that liquid sits in the pan the meat only simmers at around 100°C and stays grey. Wait for the hiss to sharpen and the pan to go dry — that's when browning and real depth start.
4. Reduce the heat to medium and sauté the finely chopped onions with the meat for 5 minutes, until they are translucent, soft, and smell sweet.
5. Sprinkle the flour over and stir it into the meat and fat for 2 minutes, until the flour is fully absorbed and no dry pockets remain — it's the flour that binds the sauce, so it needs to be distributed before the liquid goes in.
   Chef's tip The two minutes in hot fat cook off the flour's raw, pasty taste and coat each grain in fat, so it disperses instead of clumping. The mixture should look sandy and smell faintly toasted, not gluey.
6. Add the beef stock a little at a time while stirring constantly for 3 minutes. Stir each addition in completely before pouring in more, so the sauce becomes smooth without flour lumps.
7. Let the millionbøf simmer over low heat for 12-14 minutes, stirring occasionally, until the sauce has thickened and coats the back of a spoon in a thin, even layer. ⏱ 10 min–15 min
   Chef's tip The sauce keeps thickening as it simmers, so pull it while it still runs off the spoon a little loosely — it firms further off the heat and against the mash. Thin it with a splash of stock if it goes too far.
8. Stir in the browning sauce until the color is a uniform dark brown, then season with salt and freshly ground pepper. Browning sauce is burnt sugar and turns bitter if you use too much, so add it a few drops at a time, and the stock is already salty, so taste every time you add salt.
9. Drain the water from the potatoes and put the pot back on the turned-off burner for 1 minute, until the surface of the potatoes is dry and matte. The residual moisture needs to go, or the mash will turn watery.
10. Warm the whole milk and butter for the mashed potatoes together in a small saucepan for 3 minutes, until the butter has melted and the milk is steaming. Warm milk blends smoothly into the hot potatoes, while cold milk cools them down and leaves the mash stiff and heavy.
11. Mash the piping-hot potatoes with a potato masher for 2 minutes, until no whole pieces remain in the pot.
    Chef's tip Mash while they're steaming hot — cooling starch stiffens and resists, giving lumps you can't work out later. A masher or ricer crushes the cells; a blender or food processor tears them and turns the mash to glue.
12. Whisk the warm milk mixture into the mash a little at a time for 2 minutes, until the mash is creamy and light and just holds its shape on a spoon. Season it with salt and freshly grated nutmeg.
    Chef's tip Stop the moment the mash is glossy and comes together. Whisk it past that point and you release more starch, and the mash turns gluey and pulls into strings behind the spoon instead of falling softly off it.
13. Divide the creamy mashed potatoes among deep plates and press a well in the center with the back of the spoon. Ladle the hot millionbøf with sauce into the well, so the sauce stays pooled in the mash instead of running out to the edge.
