Peel the potatoes, wash them and cut them into cubes and cook, covered, in boiling, lightly salted water for about 15 to 20 minutes.
Peel and dice the onion. Melt 30 g butter in a saucepan and sauté the onion cubes until translucent. Then dust with the flour and sauté briefly. Then stir in the vegetable stock and 250 ml milk and bring to the boil while stirring. Simmer over a low heat for about 5 minutes while stirring. Then add the drained capers and season the sauce with salt, pepper and possibly a pinch of sugar.
Boil the eggs until waxy for about 7 minutes.
Heat 200 ml milk and 30 g butter in a saucepan, season with salt and about a pinch of nutmeg. Drain the potato cubes, add to the milk and mash to a puree with a potato masher. Season the mashed potatoes with salt, pepper and possibly a pinch of nutmeg.
Drain, rinse, peel and quarter the eggs. Rinse the parsley and chives and shake dry. Finely chop the parsley leaves and cut the chives into fine rolls. Stir both into the sauce and season to taste.
In a small saucepan, froth the remaining butter with the breadcrumbs. Arrange the mashed potatoes, egg quarters and sauce on plates. Drizzle the mashed potatoes with the foamed butter and sprinkle some cress on top.
Pickled beetroot goes well with it.
Tip: Sometimes, when I have some asparagus left, it is cut into pieces and added to the sauce.
Instead of mashed potatoes, you can also serve boiled potatoes or rice.
The Boss Kitchen editorial staff oversees content review, fact-checking, and recipe verification across the site. Published articles pass through the editorial team before going live, ensuring ingredient lists, techniques, cooking times, and nutritional claims hold up in a home kitchen. The team coordinates contributions across the site writers, handles reader corrections, and maintains consistency in measurement conventions, safety guidance, and dietary labeling. Posts under this byline typically represent team-reviewed reference material, site announcements, or editorial roundups rather than individual-author features, and they are held to the same sourcing standards as bylined recipe and product coverage.
