The bratwurst makes this soup special. Johnsonville or Appelbraten are my go-tos—they're pre-cooked so you skip the boiling step. Look for sausages with a good smoky aroma, not dry or stale. If you're using raw bratwurst, brown them first in a pan. The onions? Caramelize them slow and low—this is where the soup's sweetness comes from. Yellow onions work best, but red will give a milder color. Don't rush this step; it's worth the 15 minutes. Sauerkraut quality matters too—Bubbier or Reichardt brands have the best texture and tang. Rinse it if it's too acidic for your taste.
No fresh thyme? Dried works at one-third the amount, but fresh has that bright aroma. Short on time? Instant chicken broth saves 10 minutes—just add an extra splash of water. The apple cider vinegar balances the sauerkraut's tang. Substitute lemon juice if that's what you have, but it won't be quite the same. Want to make this vegetarian? Swap bratwurst for smoked tofu or vegan sausages—just increase the broth by 1 cup. The heavy cream is optional but adds a lovely richness. If you skip it, stir in a bit more butter at the end for body.
This soup tastes even better the next day—flavors meld beautifully. Store leftovers in the fridge for 4-5 days, or freeze for 3 months. I like to portion it into containers with a layer of sauerkraut on top—it keeps everything vibrant. For serving, toast some crusty sourdough and serve with a dollop of sour cream. The parsley garnish is just for looks, but it adds a fresh finish. If you make a double batch, it reheats perfectly—just add a splash of water or broth to loosen it up.

Step-by-step instructions for bratwurst and sauerkraut soup
Here’s how to make a hearty, flavorful soup that balances smoky bratwurst with tangy sauerkraut.
Caramelize Onions and Garlic for Depth
Heat a large Dutch oven over medium heat and melt the 2 tablespoons unsalted butter. Add the 1 whole yellow onion, sliced thinly, and cook for 8-10 minutes until softened and golden. You’ll see the onions release moisture and develop a sweet, caramelized aroma—this is your flavor foundation.
Push the onions to one side of the pot and add the 3 cloves minced garlic. Cook for 30 seconds until fragrant but not browned. Stir to combine with the onions, then sprinkle in the 0.5 teaspoon black peppercorns and 0.5 teaspoon fresh thyme leaves. Let them toast for 1 minute—this releases their essential oils and adds complexity to the soup.
Build the Soup Base with Bratwurst and Sauerkraut
Add the 12 ounces sliced bratwurst sausages to the pot, breaking them into bite-sized pieces if needed. Cook for 3-4 minutes until lightly browned on all sides. Remove the bratwurst with a slotted spoon and set aside temporarily.
Increase heat to medium-high and stir in the 1 tablespoon all-purpose flour, cooking for 1 minute to remove the raw flour taste. Slowly pour in the 4 cups chicken broth, stirring constantly to prevent lumps. Add the 1 tablespoon apple cider vinegar and 2 whole bay leaves, then bring to a gentle simmer. Return the bratwurst to the pot and add the 12 ounces drained sauerkraut. Simmer for 15 minutes, stirring occasionally, until the flavors meld and the sauerkraut softens.
Thicken and Finish with Cream and Herbs
Taste the soup and adjust seasoning with 1 teaspoon salt if needed. Reduce heat to low and stir in the 0.25 cup heavy cream, letting it warm through for 2-3 minutes. The cream will create a velvety texture while balancing the tangy sauerkraut.
Remove the 2 bay leaves and stir in the 0.25 cup chopped fresh parsley just before serving. The parsley adds a bright finish that cuts through the richness of the bratwurst and cream. Let the soup sit for 5 minutes off the heat to allow the flavors to settle—this makes all the difference in the final taste.
Serve Warm with Crusty Bread
Ladle the soup into bowls, ensuring each serving gets a generous portion of bratwurst and sauerkraut. The broth should coat the back of a spoon, and the bratwurst should be tender with a slightly crisp exterior. Garnish with an extra sprinkle of parsley if desired.
Serve immediately with crusty bread to soak up every last drop of that smoky, tangy goodness. The contrast of the warm soup and fresh bread makes this dish feel like a cozy hug on a chilly day. Leftovers keep well in the refrigerator for up to 3 days, and the flavors only deepen over time.
Pro Tips For Making Bratwurst Sauerkraut Soup
- Sear Bratwurst First: Don’t just toss them in—pat the sausages dry, then sear them in a hot pan for 2 minutes per side until deeply browned. This locks in flavor and keeps them from turning into soggy logs in the broth. (Yes, even if you’re impatient like me, resist the urge to rush this.)
- Rinse Sauerkraut Twice: Drain the sauerkraut, then give it a quick rinse under cold water to cut the sharpness. After the first rinse, squeeze out excess liquid—you want flavor, not a watery soup. (I learned this the hard way after serving a batch that tasted like vinegar.)
- Simmer, Don’t Boil: Once everything’s in the pot, keep the heat low enough that just tiny bubbles break the surface. Boiling toughens the bratwurst and turns the broth cloudy. A gentle simmer keeps the meat tender and the broth clear.
- Add Carrots, Skip Potatoes: Swap potatoes for 1–2 diced carrots—they soften faster and add natural sweetness without making the soup gluey. Toss them in with the onions and garlic at the start, and they’ll melt into the broth perfectly. (I skip this when I’m lazy, but the dish is noticeably better when I don’t.)
Common mistakes when making this recipe
Overcooking Bratwurst
One of the biggest mistakes I see is overcooking the bratwurst, which turns them rubbery and dry. Since we're using pre-cooked sausages, they only need 3-4 minutes to brown lightly in the pot.
If you leave them in too long, they'll lose their juicy texture. I like to remove them early and set them aside temporarily—this keeps them tender while the broth builds flavor. 🌭
Skipping Caramelization
Rushing the onion caramelization is another common error. The sweet, golden onions form the flavor base of this soup, so don't skip this step! Cook the onions over medium heat for 8-10 minutes until they're deeply caramelized.
If you're impatient, you'll miss that rich, sweet depth that makes the soup sing. I've tested this—rushed onions make a noticeably less flavorful soup.
Ignoring Sauerkraut Texture
Sauerkraut can easily turn mushy if simmered too long. The ideal texture is tender but still holding its shape—think "al dente" for cabbage. Simmer for only 15 minutes after adding it to the broth.
If your sauerkraut is particularly tough, you might need 5-10 extra minutes, but don't let it get soggy. Draining and rinsing it first also helps maintain texture.
Forgetting to Balance Tang
Many people forget that sauerkraut is already fermented and tangy. If you don't balance it with something sweet or acidic, the soup can taste overly sour. That's why I add 1 tablespoon apple cider vinegar—it brightens the flavors without overpowering.
A pinch of sugar (about ½ teaspoon) can also help if your sauerkraut is particularly sharp. Taste as you go!
Using Low-Quality Broth
Cheap, salty broth can ruin an otherwise perfect soup. Always use low-sodium chicken broth—I prefer Swanson or Pacific Foods brands. If you're using instant broth, add an extra ½ cup water to dilute the saltiness.
The broth carries all the flavors, so don't skimp here. A good broth makes the difference between a good soup and a great one.
Adding Cream Too Early
The final step is where many people go wrong—they add the cream while the soup is still boiling. This causes the cream to curdle and separate. Always stir in the heavy cream at the very end over low heat for just 2-3 minutes.
If you're worried about curdling, temper the cream first by mixing a spoonful of hot broth into it before adding it to the pot. The result should be silky, not lumpy. 🥛

Frequently asked questions
Can I make this soup without bratwurst?
For a vegetarian version, swap the bratwurst with smoked tofu or vegan sausages like Beyond Meat. Increase the broth by 1 cup to maintain soup consistency. The smoky flavor from the tofu will complement the sauerkraut beautifully.
How do I fix sauerkraut that's too sour?
Rinse the sauerkraut under cold water before adding it to the soup to reduce acidity. For extra balance, stir in 1 tablespoon apple cider vinegar or a pinch of sugar (½ teaspoon) while simmering. The cream at the end also helps neutralize the tang. Taste as you go!
Can I prepare this soup ahead of time?
Yes! This soup tastes even better the next day as flavors meld. Store leftovers in the fridge for 4-5 days or freeze for 3 months. When reheating, add a splash of water or broth to restore thickness. For serving, portion with a layer of sauerkraut on top to keep it vibrant.
What's the best way to reheat leftovers?
Gently reheat on the stove over low heat until steaming, stirring occasionally. Avoid microwaving as it can make the sauerkraut mushy. For extra richness, stir in 1 tablespoon butter or a splash of cream while reheating. The bratwurst will stay tender if warmed through carefully.
Can I use frozen sauerkraut?
Frozen sauerkraut works in a pinch, but it may be softer after thawing. Drain and rinse thoroughly to remove excess liquid. For best texture, use fresh sauerkraut—it holds its shape better during simmering. If using frozen, add it 5 minutes earlier than fresh to prevent mushiness.
