Boerenkool stamppot is a classic Dutch farmhouse supper built around a creamy mash of potatoes and tender curly kale. Here it is crowned with deeply caramelized onions, crisp smoked bacon, and a savory broth-based gravy. It is the kind of one-pot, plate-cleaning food Northern European winters were made for.

Ingredients
For the kale and potato mash
- 2 lb (900 g) Yukon gold potatoes, peeled and quartered
- 1 lb (450 g) fresh curly kale, stems removed, leaves roughly chopped
- 4 tbsp (55 g) unsalted butter
- 1/3 cup (80 ml) warm whole milk
- 1 tbsp whole-grain mustard
- 1 tsp fine sea salt, plus 1 tbsp for the cooking water
- 1/2 tsp freshly ground black pepper
For the bacon and onion gravy
- 6 oz (170 g) thick-cut smoked bacon, diced
- 1 large yellow onion, finely chopped
- 1 tbsp all-purpose flour
- 1 cup (240 ml) beef or chicken broth, warmed
- 1 tsp apple cider vinegar
- Pinch of ground nutmeg
Directions
- Bring a large pot of generously salted water to a rolling boil. Add the potatoes and simmer for 12 minutes, until they are easily pierced with a fork.
- Add the chopped kale to the same pot and cook for 4 to 5 minutes more, until the kale is silky and a deep, glossy green. Drain well, reserving 1/4 cup of the cooking liquid, then return the empty pot to low heat to keep warm.
- While the vegetables cook, place the diced bacon in a cold heavy skillet. Set over medium heat and cook for 6 to 8 minutes, stirring occasionally, until the bacon is deeply golden and crisp. Transfer to a paper-towel-lined plate, leaving about 2 tablespoons of fat in the pan.
- Add the chopped onion to the rendered bacon fat and cook over medium-low for 7 to 8 minutes, stirring often, until the onion is very soft and a deep amber color. Sprinkle in the flour, stir for 1 minute to remove the raw taste, then slowly pour in the warm broth while whisking constantly.
- Simmer the gravy for 2 to 3 minutes until it thickens to coat the back of a spoon. Stir in the vinegar, nutmeg, and half of the crispy bacon. Taste and adjust the salt and pepper.
- Return the drained potatoes and kale to the warm pot. Add the butter, warm milk, mustard, measured salt, and pepper. Mash with a sturdy potato masher until roughly smooth but still textured, adding a splash of reserved cooking liquid if it looks stiff.
- Spoon the kale mash onto warm plates and use the back of a ladle to make a shallow well in the center of each portion.
- Ladle the hot bacon-onion gravy into the wells, scatter the reserved crispy bacon over the top, and serve right away with extra mustard and a small dish of pickles on the side.
Cook’s Notes
- Use starchy russets or Yukon golds for the fluffiest mash; always warm the milk before adding so the butter does not seize.
- For a more traditional twist, swap the bacon for two smoked sausage links warmed through in the gravy before serving.
- Fold 2 tablespoons of sour cream or crème fraîche into the mash at the end for an extra tangy, creamy finish.
- Leftover stamppot reheats beautifully in a covered pan with a splash of milk to loosen it back to a creamy consistency.
- If you prefer a smoother texture, use a ricer or food mill on the potatoes before folding in the kale.
