Ingredients You’ll Need
This recipe relies on a handful of simple but star-quality ingredients, each playing a vital role to build layers of flavor and texture that transform a humble soup into an indulgent treat.
- 2 tablespoons butter: For a silky, rich base that gently cooks the vegetables without overpowering them.
- 1 onion, finely chopped: Adds natural sweetness and depth, softening into a tender, golden foundation.
- 1 leek, cleaned and thinly sliced: Brings a mild, oniony brightness with a subtle hint of earthiness.
- 1 clove garlic, minced: Infuses just the right amount of aromatic warmth to round out the veggies.
- 4 cups chicken or vegetable broth: The simmering liquid that carries all the flavors and keeps the soup hearty yet light.
- 3 tablespoons coarse Dutch mustard (Zaanse-style preferred): The star tangy ingredient that adds a bold, spicy kick with texture.
- 1/2 cup heavy cream: For that deeply creamy mouthfeel that transforms the soup into a luscious experience.
- Salt and black pepper, to taste: Essential for balancing and highlighting every ingredient’s natural flavor.
- 4 slices of thick-cut bacon, cooked and crumbled: Provides smoky crunch and savoriness that contrasts beautifully with the creamy soup.
- Fresh chives, chopped (for garnish): Adds a fresh, oniony pop and a touch of color at the finish.
- Crusty bread (optional, for serving): Perfect for dipping and soaking up every last drip of this comforting soup.
How to Make Creamy Mustard Onion and Leek Soup with Bacon and Chives Recipe
Step 1: Sauté Your Base
Start by melting the butter in a large pot over medium heat. Once melted, add the finely chopped onion, thinly sliced leek, and minced garlic. Gently sauté them until the vegetables soften and become fragrant—this usually takes around 5 to 7 minutes. This step builds the flavorful foundation of your soup, coaxing out the natural sweetness and mellow earthiness of the onions and leeks.
Step 2: Simmer with Broth
Next, pour in your chicken or vegetable broth and bring the mixture to a gentle simmer. Let it cook for 10 minutes to allow all those flavors to mingle and deepen. This simmering is crucial because it blends the vegetables’ essence into the liquid, enriching every spoonful of your final soup.
Step 3: Add the Bold Mustard Flavor
Now comes the exciting part: stirring in the beautiful coarse Dutch mustard. Using about 3 tablespoons, add it to your simmering pot and continue to cook for another 5 minutes. This step infuses the soup with a lively, zesty character and that unique grainy texture that keeps each bite interesting.
Step 4: Blend and Creamify
Remove the pot from the heat and use an immersion blender to puree the soup. You can blend it completely smooth or leave it a little chunky for more texture—whichever you prefer. Then stir in the heavy cream, seasoning with salt and freshly ground black pepper to taste. Heat the soup gently until warmed through, but be careful not to let it boil after adding the cream, so it stays luxuriously velvety.
Step 5: Finish with Bacon and Chives
Ladle your soup into warm bowls and sprinkle the crispy crumbled bacon on top along with a scattering of fresh chives. These garnishes introduce a delightful crunch and fresh bite, perfectly complementing the creamy, tangy soup beneath.

Garnishes
Don’t underestimate the power of simple garnishes! The crumbled bacon brings a smoky, salty crunch, while bright green chopped chives add fresh color and a mild onion flavor that lifts the whole bowl. These little touches make your soup feel like a special treat every time.
Side Dishes
For a complete meal, serve this soup alongside crusty bread—ideally a fresh baguette or a rustic sourdough. The crunchy bread is perfect for dipping and soaking up every creamy, mustardy drop. A simple green salad with a light vinaigrette also pairs beautifully, balancing out the richness of the soup.
Creative Ways to Present
Want to impress guests or make your weeknight dinner feel a bit fancier? Serve the soup in individual ramekins or hollowed-out bread bowls for an eye-catching presentation. Swirl a little extra dollop of cream on top or sprinkle some extra mustard seeds for texture and visual appeal. This soup is so versatile, you can get creative without overwhelming its delicate yet bold flavor profile.
Make Ahead and Storage
Storing Leftovers
You can store leftovers of the Creamy Mustard Onion and Leek Soup with Bacon and Chives Recipe in an airtight container in the refrigerator for 3 to 4 days. The flavors often deepen overnight, making the next-day soup even better!
Freezing
If you want to freeze the soup, wait until it cools completely, then transfer it to freezer-safe containers. It will keep well for up to 3 months. When ready to eat, thaw overnight in the fridge for the best texture and taste retention.
Reheating
Reheat leftovers gently on the stovetop over low heat, stirring often to prevent the cream from separating or the soup from sticking. Avoid boiling; just warm until hot enough to enjoy. You can also re-season with a little extra salt, pepper, or mustard if the flavor has mellowed.
FAQs
Can I use a different type of mustard in this soup?
Absolutely! While coarse Dutch mustard (Zaanse-style) gives this soup its authentic texture and tang, you can substitute with any grainy or whole-grain mustard. Just keep in mind that flavor intensity will vary, so start with less and adjust to taste.
Is it possible to make this soup vegetarian?
Yes! Use vegetable broth instead of chicken broth and either skip the bacon or use a plant-based bacon alternative. Fresh chives will still add a lovely burst of flavor to keep the soup satisfying and aromatic.
Can I prepare this soup in advance for a gathering?
Definitely. This soup is fantastic made a day in advance because the flavors meld beautifully overnight. Just keep the garnishes separate until serving to maintain their crispness and freshness.
What if I don’t have an immersion blender?
You can transfer the soup carefully in batches to a regular blender and puree until smooth. Just be cautious with hot liquids and blend in small amounts to avoid splatters.
How do I store the soup if I want to keep the bacon crispy?
Store the soup and the cooked crumbled bacon separately. Add the bacon right before serving to maintain that perfect crunch and smoky contrast.
