Peel and chop the potatoes into consistent 2-3 cm chunks. Place them in a large pot, cover with cold water, and add a generous pinch of salt. Bring to a boil over high heat, then reduce to a simmer and cook for approximately 15 minutes, or until potatoes are tender when pierced with a fork.
02 -
Thoroughly drain the cooked potatoes. Return them to the warm pot. Add the 60 g of butter and warm milk or cream. Mash vigorously with a potato masher or ricer until smooth and creamy. Season generously with salt and pepper. Cover the pot to keep the mashed potatoes warm while preparing the gravy.

In a large skillet, brown the ground beef over medium-high heat, breaking it apart with a spoon as it cooks. Continue until the beef is fully cooked through and no pink remains. Drain any accumulated fat from the skillet.
04 -
Add the finely diced onion to the skillet with the browned beef. Sauté for 5-7 minutes, stirring occasionally, until the onion softens and becomes translucent.
05 -
Sprinkle the all-purpose flour evenly over the beef and onion mixture. Stir constantly for 1-2 minutes, ensuring the flour coats the ingredients and cooks slightly, forming a roux that will thicken the gravy.
06 -
Gradually pour in the beef broth while continuously whisking to prevent lumps. Add the Worcestershire sauce, garlic powder, dried thyme (if using), salt, and black pepper. Bring the mixture to a gentle simmer, whisking frequently.
07 -
Reduce the heat to medium-low and continue to simmer the gravy for approximately 10 minutes, stirring occasionally, until it thickens to a rich, glossy, and spoon-coating consistency.
08 -
Remove the skillet from the heat. Stir in the remaining 15 g of butter until it is completely melted and fully incorporated into the gravy. This step enhances the richness and provides a silky-smooth finish.
09 -
Generously scoop the warm, creamy mashed potatoes onto serving bowls or plates. Ladle a copious amount of the savory beef gravy directly over the mashed potatoes.

For an appealing presentation, garnish the dish with a sprinkle of fresh thyme or a final crack of black pepper.
