Description

A comforting and creamy Dutch mustard soup featuring a blend of sautéed onion, leek, and garlic simmered in broth, enriched with coarse Zaanse-style mustard and heavy cream, topped with crispy bacon and fresh chives. Perfect served hot alongside crusty bread for a warm and flavorful meal.


Ingredients

Scale

Sauté Base

  • 2 tablespoons butter
  • 1 onion, finely chopped
  • 1 leek, cleaned and thinly sliced
  • 1 clove garlic, minced

Soup

  • 4 cups chicken or vegetable broth
  • 3 tablespoons coarse Dutch mustard (Zaanse-style preferred)
  • 1/2 cup heavy cream
  • Salt and black pepper, to taste

Toppings and Serving

  • 4 slices of thick-cut bacon, cooked and crumbled
  • Fresh chives, chopped (for garnish)
  • Crusty bread (optional, for serving)


Instructions

  1. Sauté Vegetables: In a large pot, melt butter over medium heat. Add the finely chopped onion, cleaned and thinly sliced leek, and minced garlic. Sauté until softened and fragrant, about 5-7 minutes.
  2. Add Broth and Simmer: Pour in the chicken or vegetable broth and bring the mixture to a gentle simmer. Let it cook for about 10 minutes to blend the flavors.
  3. Incorporate Mustard: Stir in the coarse Dutch mustard and continue simmering the soup for another 5 minutes, allowing the mustard flavor to fully infuse the broth.
  4. Blend Soup: Remove the pot from heat and use an immersion blender to puree the soup until smooth, or leave it slightly chunky if you prefer texture.
  5. Add Cream and Seasoning: Stir in the heavy cream and season with salt and black pepper to taste. Heat the soup gently without bringing it to a boil to prevent curdling.
  6. Serve: Ladle the hot soup into bowls, topping each with crumbled crispy bacon and fresh chopped chives. Serve immediately with crusty bread on the side if desired.

Notes

  • Use coarse Zaanse-style Dutch mustard for the authentic bold flavor and texture.
  • For a vegetarian version, substitute chicken broth with vegetable broth and omit bacon or use vegetarian bacon alternatives.
  • When blending, be careful not to over-blend if you prefer some texture in your soup.
  • Heavy cream can be substituted with half-and-half for a lighter version, but may affect richness.
  • Crusty bread is optional but adds a nice accompaniment for dipping.
