📝 About This Recipe

A soul-warming staple of Northern German winter cuisine, Kohlwurst is a robust, smoked pork sausage traditionally simmered atop a bed of savory braised kale. This dish, often referred to as 'Kohl und Pinkel' in its regional variations, delivers a smoky, fatty richness that perfectly cuts through the earthy bitterness of the greens. It is the ultimate comfort food for a cold evening, representing centuries of Hanseatic culinary tradition and the art of slow-cooked, one-pot perfection.

🥗 Ingredients

The Sausages

  • 6 pieces Kohlwurst (or Mettwurst) (high-quality smoked pork sausages)
  • 150 grams Smoked Slab Bacon (Speck) (diced into small cubes)
  • 500 grams Kassler (Smoked Pork Loin) (cut into thick slices; optional but traditional)

The Braised Kale (Grünkohl)

  • 1.5 kg Fresh Curly Kale (stems removed, leaves thoroughly washed and roughly chopped)
  • 2 large Yellow Onions (finely diced)
  • 2 tablespoons Lard or Clarified Butter (Schmalz) (goose or pork lard is most authentic)
  • 500 ml Beef or Vegetable Stock (high quality)
  • 3-4 tablespoons Oat Flakes (Rolled Oats) (used to thicken the kale juices)
  • 1 tablespoon German Mustard (Mittelscharf) (medium-hot variety)
  • 1 teaspoon Sugar (to balance the bitterness)
  • to taste Salt and Black Pepper (be careful with salt as sausages are salty)
  • 1/4 teaspoon Allspice (ground)

Accompaniments

  • 800 grams Small Waxy Potatoes (peeled and boiled)
  • 2 tablespoons Butter (for sautéing the potatoes)

👨‍🍳 Instructions

  1. 1

    Prepare the kale by removing the tough center ribs. Blanch the leaves in a large pot of boiling salted water for 2-3 minutes until wilted, then drain and immediately shock in ice water to preserve the color.

  2. 2

    Squeeze the excess water out of the blanched kale and chop it roughly. Set aside.

  3. 3

    In a large, heavy-bottomed Dutch oven or pot, melt the lard over medium heat. Add the diced bacon (speck) and fry until the fat renders and the bacon begins to crisp.

  4. 4

    Add the diced onions to the pot with the bacon. Sauté for about 5-7 minutes until the onions are translucent and slightly golden.

  5. 5

    Stir in the chopped kale, coating it thoroughly in the bacon fat and onions. Cook for a few minutes until the kale further collapses.

  6. 6

    Pour in the stock until the kale is nearly covered. Add the mustard, sugar, and ground allspice. Stir well to combine.

  7. 7

    Place the Kassler pork slices (if using) into the kale mixture, nestling them down so they are submerged. Bring to a gentle simmer, cover with a lid, and cook for 45 minutes.

  8. 8

    After 45 minutes, prick the Kohlwurst sausages a few times with a fork (this allows the flavorful fat to seep into the kale) and lay them on top of the kale.

  9. 9

    Sprinkle the oat flakes over the mixture. The oats will dissolve and thicken the liquid into a silky sauce. Cover and simmer for another 30 minutes.

  10. 10

    While the kale simmers, boil the peeled potatoes in salted water until tender (about 15-20 minutes). Drain and, if desired, quickly toss them in a pan with butter and a pinch of sugar to glaze them.

  11. 11

    Check the kale for seasoning. The sausages and bacon provide significant salt, so add salt only after tasting. Add plenty of freshly cracked black pepper.

  12. 12

    To serve, place a generous portion of kale on a plate, top with a Kohlwurst and a slice of Kassler, and serve the potatoes on the side.

💡 Chef's Tips

Always prick the sausages before adding them to the pot; the rendered fat is the secret to the best tasting kale. If you cannot find Kohlwurst, a high-quality smoked Kielbasa or Andouille can serve as a substitute, though the flavor profile will shift. Kale actually tastes better after the first frost, which converts starches to sugars; if buying fresh in summer, freeze it overnight before cooking to mimic this effect. Don't skip the oats! They are the traditional thickening agent and provide a unique, creamy texture to the greens. This dish is even better the next day, as the flavors of the smoke and spices deepen overnight in the fridge.

🍽️ Serving Suggestions

Pair with a cold Northern German Pilsner or a robust Rauchbier (smoked beer) to complement the smokiness of the meat. A side of sharp German sweet mustard is essential for dipping the sausage. Serve with 'Bratkartoffeln' (fried potatoes) instead of boiled potatoes for extra crunch. A glass of Aquavit served chilled as a digestif is the traditional way to end this heavy, satisfying meal. For a touch of sweetness, some regions serve this with caramelized sugar-glazed potatoes.
