The kielbasa is non-negotiable—look for smoked varieties at Trader Joe’s or Whole Foods (their house brands are excellent). Avoid pre-cooked versions that lack depth. Sauerkraut should be fresh-packed, not canned, for the best texture. Boar’s Head or Silver Floss are reliable brands if your store carries them. The apple adds subtle sweetness—Granny Smith holds up best to slow cooking.
No caraway seeds? Fennel seeds at half the amount work in a pinch. Swap Dijon for whole-grain mustard if you prefer texture. Apple cider vinegar can be white wine vinegar (use slightly less). For extra richness, add 1 tbsp of butter at the end. The broth can be swapped for vegetable broth without issue.
Leftovers keep 4-5 days refrigerated in an airtight container. Flavors deepen overnight—best served the next day. Freezes well for 2-3 months. Reheat gently to avoid breaking the sausage casings.

Step-by-Step Instructions for Smoky Sausage and Sauerkraut Simmer
This hands-off method delivers tender sausage and tangy sauerkraut with minimal effort.
Step 1: Prepare and Layer the Base Ingredients
Begin by slicing the 1 lb Kielbasa Sausage into ½-inch rounds. I prefer to cut them slightly thicker so they hold their shape during cooking. Arrange the sliced sausage in an even layer at the bottom of your slow cooker—this creates a solid foundation for the other ingredients.
Next, spread the 2 cups Sauerkraut evenly over the sausage. If you’ve rinsed it, squeeze out any excess moisture to prevent a watery finished dish. The sauerkraut should cover the sausage completely, as it will absorb flavors and soften beautifully as everything simmers.
Step 2: Add Aromatics and Sweet-Tangy Elements
Thinly slice the 1 whole Yellow Onion and scatter it over the sauerkraut. Then, peel, core, and dice the 1 whole Granny Smith Apple and add it to the slow cooker. The apple’s tartness balances the richness of the sausage and the tang of the sauerkraut.
In a small bowl, whisk together the 2 tbsp Light Brown Sugar, 1 tbsp Dijon Mustard, and 1 tbsp Apple Cider Vinegar until smooth. Pour this mixture evenly over the top of the layered ingredients. This step ensures every bite carries a perfect balance of sweet, tangy, and savory flavors.
Step 3: Season and Infuse with Liquid
Sprinkle the 1 tsp Caraway Seeds and 0.5 tsp Black Pepper evenly over the top. Caraway is the signature spice in sauerkraut dishes, adding a warm, earthy depth. Add the 1 whole Bay Leaf and minced 3 cloves Garlic Cloves, tucking them into the mixture so they infuse throughout.
Finally, pour the 0.5 cup Chicken Broth around the edges of the slow cooker. Avoid pouring it directly over the sauerkraut to prevent washing away the spices. The broth adds moisture and helps meld all the flavors together without diluting them.
Step 4: Cook on Low and Serve
Cover the slow cooker and set it to low heat for 4-5 hours. This gentle cooking method allows the sausage to absorb the flavors of the sauerkraut, apple, and spices without becoming mushy. You’ll know it’s ready when the sausage is heated through and the sauerkraut is tender but still has a slight bite.
Discard the bay leaf before serving. The dish should have a rich, slightly glossy sauce from the melted sugar and rendered fats. Serve warm, straight from the slow cooker, with crusty bread or mashed potatoes to soak up every last bit of the flavorful liquid.
Pro Tips For Making Recipe For Kielbasa In Crock Pot
- Brown the Kielbasa: Sear the kielbasa in a pan for 2-3 minutes per side before adding to the crock pot—it deepens the flavor and keeps the texture from turning mushy.
- Rinse the Sauerkraut: Drain and rinse the sauerkraut under cold water to cut the sourness, then squeeze out excess liquid so your dish isn’t watery.
- Skip Unpeeled Apples: Peel the Granny Smith apple first—otherwise, the skin stays tough and chewy even after hours in the slow cooker.
- Add Sugar Last: Stir in the light brown sugar during the last 30 minutes to prevent it from dissolving too early and making the sauerkraut soggy.
Best Sauces and Condiments for This Dish
Classic Mustard Sauce
Whisk ½ cup Dijon mustard with 2 tbsp honey and 1 tbsp apple cider vinegar for a tangy-sweet glaze. I like to add 1 tsp caraway seeds to echo the dish’s flavors. Drizzle over the finished creation just before serving. 💛
Creamy Horseradish
Combine ½ cup sour cream with 2 tbsp prepared horseradish and 1 tsp lemon juice. This adds a cool, sharp contrast to the smoky sausage. I use Gold’s horseradish from my local market—it’s got just the right kick.
Sweet Apple Compote
Simmer 1 diced Granny Smith apple with 2 tbsp brown sugar and ¼ cup chicken broth until soft. The apple’s natural sweetness complements the dish beautifully. I often make extra for leftovers.
Spicy Beer Mustard
Mix ¼ cup whole-grain mustard with 2 tbsp dark beer and 1 tsp hot sauce. This adds depth and heat. I prefer Guinness for its rich, roasted notes that pair well with kielbasa. 🔥
Buttery Breadcrumbs
Toast ½ cup panko breadcrumbs in 2 tbsp melted butter until golden. Sprinkle on top for crunch. I always keep Progresso breadcrumbs on hand for quick additions like this.

Frequently Asked Questions
Can I use a different type of sausage?
Yes, but smoked varieties work best. Andouille or bratwurst can substitute, though flavors will differ slightly. Avoid fresh sausages as they need full cooking.
How do I prevent the sauerkraut from getting mushy?
Don’t overcook! Stick to 4-5 hours on low. Drain and rinse the sauerkraut first to remove excess liquid. The apple helps maintain texture too.
What’s the best way to reheat leftovers?
Gently warm on the stovetop with a splash of broth. Microwaving works but can dry out the sausage. Always cover to retain moisture.
Can I add potatoes to the slow cooker?
Add 1 lb baby potatoes (halved) in the last 2 hours to prevent them from turning to mush. They’ll soak up all the great flavors.
