Creamy Sausage, Potato and Sauerkraut Soup – A Tangy Twist with Probiotic Sauerkraut for Comfort

I grew up on the bustling streets of Casablanca, where the aroma of spiced chilies and simmering tagines would seep into every corner of a family home. When I moved to Paris for culinary school, the crisp French techniques of beurre blanc and roux were my new best friends. Now, in New York City, I love to blend those worlds—bringing the earthy zing of sauerkraut and the comforting N’Awald’s broth into a quick, creamy soup that feels like a hug on a weekday night.

Each spoonful invites a delightful contrast: the cool tang of sauerkraut, the hearty chew of diced potatoes, the savory melt of kielbasa, and the velvety cream of cheddar. The broth thickens into a silky custard that coats the starch, while the fermented greens lend a quiet depth—almost like walking through a smoky, European forest in a single bowl.

What sets this version apart is the time‑saved step that turns a braised sauerkraut into a creamy emulsion—no need to simmer for hours. I’ll share a pro tip: use a small amount of flour for a lighter roux that gives the soup a smooth mouthfeel. One common pitfall is over‑stirring the cheese near the end; it can string and pull thin flavors. Keep your heat low once the cheddar is added and let it melt gently.

Why This Creamy Sausage, Potato and Sauerkraut Soup Recipe Is the Best

My French grounding taught me that flavor should rise from every layer: the roux, the simmered onions, and the final cheese. By inviting sauerkraut’s tartness, I give the soup a probiotic kick that balances the richness of the sausage and cheese—making it a wholesome, immune‑boosting meal.

The texture hits the sweet spot: crispy sausage and soft potatoes glued together by a creamy base, resulting in a bowl that feels both hearty and yet under‑stated, perfect for a board‑room lunch or a rainy evening.

And best of all, the method is beginner‑friendly—no specialized equipment needed. Just a saucepan, a sneak a half–sec of roux, and a handful of patience. By following my step‑by‑step instructions, anyone can create a soup that tastes as authentic as a Moroccan couscous dinner, yet feels fresh in a New York kitchen.

Creamy Sausage, Potato and Sauerkraut Soup Ingredients

I find the butter, onions, and sausages at the Greenwich Village farmer’s market, while the sauerkraut packs go for my favorite organic store in Midtown. The cheddar—look for a sharp, crumb‑free blade—comes from a boutique cheese counter downtown. The ingredients are farm‑fresh, locally sourced, and, in the end, a soul‑satisfying feast.

Ingredients List

• 4 tablespoons butter
• 1 medium onion, finely diced
• ¼ cup all‑purpose flour
• 1 ½ cups chicken broth
• 2 ½ cups milk
• 1 – 14 oz kielbasa sausage, halved and sliced
• 1 ½ cups cooked diced potatoes
• 1 cup sauerkraut, with juice
• ½ teaspoon dried parsley
• 1 cup shredded cheddar cheese
• black pepper, to taste

Ingredient Spotlight

Kielbasa: The smoky, paprika‑infused sausage from Eastern Europe adds depth. Look for one that’s fresh and lightly smoked to capture a quick char without excess oil. If you want a vegetarian option, try roasted butternut squash chunks.

Sauerkraut: Whole‑grain fermented cabbage gives that bright tartness and probiotics. Buy it from natural stores or make your own for maximum freshness. A fair swap is acid‑tossed red cabbage for a sweeter twist.

Cheddar: Choose a sharp cheddar with firm crumb. If you prefer a smoother melt, use Gruyère or a mild cheddar. The cheese’s texture changes the soup’s thickness—cheddar for a creamy mouthfeel, Gruyère for a nuttier bite.

How to Make Creamy Sausage, Potato and Sauerkraut Soup — Step-by-Step

Let’s bring the flavors together with a simple yet mindful approach—an elegant “one‑pot” method that keeps the kitchen clutter free.

Step 1: Sauté Onion

In a large saucepan, melt 4 tablespoons butter over medium heat. Add the finely diced onion and sauté for about five minutes until translucent and soft, releasing sweet aroma.

💡 Samantha’s Pro Tip: Stir the onions often—this promotes even caramelization and brings out their natural sweetness.

Step 2: Add Flour

Add ¼ cup all‑purpose flour, stirring continuously until the mixture turns a light golden brown—this creates a roux that thickens the soup. Cook for about one minute to remove raw flour taste.

⚠️ Common Mistake to Avoid: Don’t let the roux burn—keep the heat moderate and stir until it’s just browned.

Step 3: Add Broth & Milk

Gradually whisk in 1 ½ cups chicken broth followed by 2 ½ cups milk, stirring constantly to prevent lumps. Turn the heat to medium‑high, then cook, stirring often, until the mixture thickens and simmers.

💡 Samantha’s Pro Tip: Whisk slowly; this ensures a smooth, spearmint‑like texture that makes the soup feel like a velvety classic.

Step 4: Add Sausage, Potatoes & Sauerkraut

Reduce heat to medium, then add sliced kielbasa, cooked diced potatoes, 1 cup sauerkraut (with juice), and ½ teaspoon dried parsley. Simmer for five minutes to let the flavors marry.

⚠️ Common Mistake to Avoid: Over‑add potatoes—too many chunks can overwhelm the broth and make it watery.

Step 5: Add Cheddar

Turn off the heat. Stir in 1 cup shredded cheddar until completely melted. Season with black pepper to taste, then spoon the soup into bowls and sprinkle extra pepper for a finale.

💡 Samantha’s Pro Tip: Use a smaller chunk of cheddar for a lighter melt and a major flavor burst.

Serving & Presentation

Plate the soup in warmed bowls; drizzle a swirl of sour cream or a few crunchy oven‑roasted crackers. Garnish with a sprinkle of chopped dill or a pinch of smoked paprika for extra color. If you’re a fan of NYC’s street food vibe, top with a crumble of crispy bacon.

I recommend pairing this hearty soup with a crisp Chianti—or a sparkling apple cider for a light contrast. The acidity of the wine and the depth of the soup dance together like a city accordion matching a melody.

Make-Ahead, Storage & Reheating

After lunch, I seal the soup in a glass jar or a Tupperware and refrigerate. Monday evenings, I simply reheat in a saucepan with a splash of milk to restore creaminess. Freezing is best for up to two months; thaw in the fridge overnight and gently simmer.

When reheating, avoid boiling as this can separate the cheese. A slow simmer on low heat with a splash of milk or broth keeps the soup cream‑y and prevents over‑cooking the potatoes.

Variations & Easy Swaps

Vegetarian Herb‑Infused Variation

I sliced zucchini into bite‑size chunks and sautéed them with onions. I swapped the kielbasa for a firm tofu block, lightly pan‑fried for crispness, and sprinkled fresh thyme and oregano after buttering. The result is a light yet flavorful soup that still brings that comforting, savory base.

Gluten‑Free / Dairy‑Free Variation

First, I used a gluten‑free all‑purpose blend for the roux. Then I replaced the milk with unsweetened almond milk and swapped cheddar for a plant‑based cheddar alternative. The soup remains creamy, but the texture is lighter, and the dairy‑free version keeps the flavor profile intact. I tested it in my week‑long meal plan and loved how it worked with a fruit salad.

Seasonal Summer Sweet‑Potato Variation

I roasted sweet potatoes with a bit of olive oil and salt, then cut them into pieces to add during step 4. A pinch of ground cumin and smoked paprika adds earthiness, while the sweet potatoes soften the broth into a warm orange hue. The city‑fresh menu offers a light, colorful alternative for summer brunches.
