🥗 Ingredients

The Bread Base

  • 250 grams Stale Sourdough Rye Bread (Bauernbrot) (crusts included, cut into 1-inch cubes)
  • 2 tablespoons Unsalted Butter (high-quality European style preferred)

The Aromatics & Liquid

  • 1 medium Yellow Onion (finely diced)
  • 1.2 liters Beef Stock (rich, homemade or low-sodium store-bought)
  • 1 piece Garlic Clove (minced)
  • 1/2 teaspoon Caraway Seeds (slightly crushed to release oils)

Seasoning & Finishing

  • 100 ml Heavy Cream (for a silky finish)
  • 2 large Egg Yolks (at room temperature)
  • 1/4 teaspoon Ground Nutmeg (freshly grated)
  • to taste Sea Salt
  • to taste Black Pepper (freshly cracked)

For Garnish

  • 2 tablespoons Fresh Chives (finely snipped)
  • 1 slice Extra Rye Bread (fried in butter for croutons)
  • 50 grams Bacon Bits (Schinkenwürfel) (optional, crispy fried)

👨‍🍳 Instructions

  1. 1

    Begin by cubing your stale rye bread into 1-inch pieces. If the bread is still fresh, toast the cubes in a 300°F (150°C) oven for 10 minutes to dry them out.

  2. 2

    In a large heavy-bottomed pot or Dutch oven, melt the 2 tablespoons of butter over medium heat until it begins to foam.

  3. 3

    Add the finely diced onions to the pot. Sauté for 5-7 minutes until they are translucent and just beginning to turn golden brown around the edges.

  4. 4

    Stir in the minced garlic and crushed caraway seeds. Cook for only 60 seconds until fragrant, being careful not to burn the garlic.

  5. 5

    Add the bread cubes to the pot, stirring them into the butter and onions for 2-3 minutes to allow them to absorb the flavors and lightly toast.

  6. 6

    Pour in the beef stock. Increase the heat to medium-high and bring the mixture to a gentle boil.

  7. 7

    Once boiling, reduce the heat to low. Cover the pot and let it simmer for 15-20 minutes. The bread should completely break down and soften into the liquid.

  8. 8

    For a traditional rustic texture, use a whisk to break up any remaining large chunks of bread. For a modern, velvety finish, use an immersion blender to purée the soup until completely smooth.

  9. 9

    In a small bowl, whisk together the heavy cream and the two egg yolks. This is the 'legieren' technique used to thicken and enrich the soup.

  10. 10

    Temper the egg mixture by adding a ladleful of the hot soup into the bowl while whisking constantly. This prevents the eggs from scrambling.

  11. 11

    Slowly pour the tempered egg and cream mixture back into the pot. Stir constantly over very low heat for 1-2 minutes. Do not let the soup boil again or the eggs will curdle.

  12. 12

    Season with freshly grated nutmeg, salt, and black pepper. Taste and adjust as needed.

  13. 13

    While the soup rests, fry the extra bread cubes and bacon bits in a small skillet until crispy.

  14. 14

    Ladle the hot soup into warmed bowls. Garnish generously with the snipped chives, crispy croutons, and bacon bits.

💡 Chef's Tips

Always use a dark, sourdough-based rye bread (like Pumpernickel or Roggenbrot) for the best flavor; white bread will result in a bland soup. If your soup becomes too thick, simply thin it with a splash of warm beef stock or water until you reach your desired consistency. To make it vegetarian, substitute the beef stock with a robust mushroom or roasted vegetable broth and omit the bacon bits. Be extremely careful when adding the egg yolks; the soup must be off the boil to ensure a smooth, custard-like texture rather than a lumpy one. Freshly grated nutmeg is essential—the pre-ground version loses the volatile oils that provide the soup's characteristic aroma.

🍽️ Serving Suggestions

Serve with a cold glass of Bavarian Weissbier (wheat beer) to cut through the richness of the cream. Pair with a side of crisp radishes and a small green salad with a sharp vinaigrette for a balanced lunch. A small dollop of sour cream on top adds a lovely acidic brightness to the earthy rye flavors. For a truly traditional experience, serve in a hollowed-out small loaf of crusty bread. Follow the meal with a warm apple strudel for the ultimate German comfort food experience.
