Dutch Mustard Soup Recipe
Introduction
Dutch Mustard Soup is a rich and comforting dish, perfect for chilly days. Its creamy texture combined with the tangy bite of stoneground mustard and crispy bacon creates a deliciously balanced flavor. This classic soup is simple to make and sure to warm you up from the inside out.

Ingredients
- 1/2 lb cubed bacon or pancetta
- 1-2 tablespoons unsalted butter, if needed
- 1 large white onion, chopped
- 2 leeks, trimmed and chopped
- 2 cloves garlic, minced
- 3 tablespoons stoneground mustard
- 3 cups vegetable or chicken stock
- 1 cup heavy cream or half-and-half
- 1 tablespoon cornstarch (optional)
- Kosher salt and freshly ground pepper, to taste
Instructions
- Step 1: In a large pot, cook the cubed bacon or pancetta over medium-high heat until browned and crispy. Remove the cooked bacon to a paper towel-lined plate to drain excess fat.
- Step 2: If there isn’t much fat left in the pot, add butter to reach about 2 tablespoons of fat total. Reduce the heat to medium.
- Step 3: Add the chopped onion and leeks to the pot. Cook them gently until they become soft, about 5 minutes. Add the minced garlic and cook for one more minute, stirring frequently.
- Step 4: Stir in the stoneground mustard, then pour in the stock and cream. Bring the soup to a simmer and cook until the vegetables are tender, approximately 10 minutes.
- Step 5: Use an immersion blender to puree the soup directly in the pot, or carefully transfer it to a blender to process until smooth.
- Step 6: If you prefer a thicker consistency, mix the cornstarch with 2 tablespoons of cold water and stir it into the soup. Let it simmer until it thickens.
- Step 7: Season the soup with kosher salt and freshly ground pepper to taste. Serve hot, topped with the crispy bacon or pancetta you set aside earlier, and enjoy!
Tips & Variations
- For a smoky depth, use smoked bacon or pancetta.
- Substitute heavy cream with half-and-half for a lighter version.
- If you like a stronger mustard flavor, add an extra tablespoon of stoneground mustard.
- Serve with crusty bread for a hearty meal.
Storage
Store leftover soup in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat, stirring occasionally to prevent scorching. If the soup thickens too much when chilled, add a splash of stock or cream while reheating to loosen the consistency.

FAQs
Can I use yellow mustard instead of stoneground mustard?
Yes, you can substitute yellow mustard if stoneground is not available, but the soup will have a milder texture and less grainy flavor.
Is this soup suitable for vegetarians?
To make a vegetarian version, omit the bacon or pancetta and use vegetable stock. You can add a smoky flavor by including smoked paprika or liquid smoke.

Ingredients
Meat and Fat
- 1/2 lb cubed bacon or pancetta
- 1–2 tablespoons unsalted butter, if needed
Vegetables
- 1 large white onion, chopped
- 2 leeks, trimmed and chopped
- 2 cloves garlic, minced
Liquids and Seasoning
- 3 tablespoons stoneground mustard
- 3 cups vegetable or chicken stock
- 1 cup heavy cream or half-and-half
- 1 tablespoon cornstarch (optional)
- Kosher salt and freshly ground pepper, to taste
Instructions
- Cook the bacon or pancetta: In a large pot over medium-high heat, cook the cubed bacon or pancetta until browned and crispy. Once done, transfer the cooked meat to a paper towel lined plate to drain excess fat.
- Prepare the fat base: If the pan has too little fat remaining after cooking the bacon (less than 2 tablespoons), add unsalted butter to the pot to reach about 2 tablespoons of fat total for sautéing.
- Sauté the vegetables: Reduce the heat to medium, then add the chopped onion and leeks to the pot. Cook them until they become soft and translucent, about 5 minutes. Add the minced garlic and cook for an additional minute to release its aroma.
- Add mustard and liquids: Stir in the stoneground mustard making sure it evenly coats the vegetables. Then pour in the vegetable or chicken stock followed by the heavy cream or half-and-half. Bring the soup to a simmer and cook until the vegetables are tender, about 10 minutes.
- Puree the soup: Use an immersion blender directly in the pot to puree the soup until smooth. Alternatively, carefully transfer the soup to a blender and blend until creamy.
- Optional thickening: If a thicker consistency is desired, mix 1 tablespoon of cornstarch with 2 tablespoons of cold water to create a slurry. Stir this into the soup and let it simmer until it thickens.
- Season and serve: Taste the soup and adjust seasoning with kosher salt and freshly ground black pepper. Ladle into bowls, top with the crispy bacon or pancetta pieces, and serve warm.
Notes
- You can substitute pancetta with bacon or a similar cured pork product as per preference.
- For a lighter version, use half-and-half instead of heavy cream.
- Stoneground mustard gives texture and piquancy, but smooth mustard can be used for a silkier soup.
- The cornstarch slurry is optional; the soup will be creamy but thinner without it.
- Serve with crusty bread or a light salad for a balanced meal.
