There’s a reason this dish has been a Midwestern staple for generations—it delivers hearty comfort with almost no effort. The slow cooker transforms simple ingredients into something deeply satisfying, blending smoky sausage with tangy sauerkraut.
I’ve tested this method through countless winter nights, and the secret lies in the low-and-slow approach. Just layer the ingredients, set the timer for 6 hours, and let the crock pot work its magic.
What emerges is a meal rich with tradition yet effortlessly modern. The sausage stays juicy, the sauerkraut mellows into tender perfection, and the whole house fills with an irresistible aroma.
Serve it with crusty bread or mashed potatoes for a complete, soul-warming dinner. This is comfort food at its most reliable.
Ingredients for Polish Sausage and Sauerkraut Recipe Crock Pot
Hearty sausage and tangy kraut come together for slow-cooked comfort in a crock pot.
| Ingredient | Amount | Notes |
|---|---|---|
| Polish Sausage 🌭 | 1 ½ lb | Kielbasa, sliced into rounds |
| Sauerkraut 🥬 | 1 lb | Rinsed and drained well |
| Yellow Onion 🧅 | 1 whole | Large, thinly sliced |
| Granny Smith Apple 🍏 | 1 whole | Peeled, cored, diced |
| Chicken Broth 🍲 | 1 cup | Low-sodium preferred |
| Brown Sugar 🫙 | 2 tbsp | Light or dark variety |
| Caraway Seeds 🌿 | 1 tsp | Lightly crushed for flavor |
| Dijon Mustard 🟡 | 1 tbsp | Smooth, not whole grain |
| Garlic Cloves 🧄 | 3 cloves | Minced finely |
| Juniper Berries 🫶 | 4 pieces | Lightly crushed, optional |
| Bay Leaf 🌿 | 1 whole | Dried, for depth |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
The sausage is key here. Kielbasa from a quality butcher or Hillshire Farm at the grocery store both work well—avoid pre-cooked varieties with added fillers. Sauerkraut should be refrigerated, not shelf-stable, for the best texture and flavor. Libby’s or Silver Floss are reliable brands. Look for kraut packed in brine, not vinegar, for authentic tang without harshness.
No Polish sausage? Smoked sausage or bratwurst can substitute in a pinch. Skip the apple if you prefer, but it adds a subtle sweetness that balances the dish. For a richer broth, swap chicken for vegetable stock. Mustard can be yellow or whole grain if Dijon isn’t on hand. The caraway seeds are traditional but can be omitted if you’re not a fan.
Leftovers keep 4-5 days in the fridge and reheat well. Freeze for up to 3 months in airtight containers. The flavor deepens over time, making this even better the next day. Perfect for meal prep or feeding a crowd.

Step-by-Step Instructions for Polish Sausage and Sauerkraut Crock Pot
This method delivers tender sausage and perfectly balanced flavors with minimal effort.
Step 1: Prepare and Layer the Base Ingredients
Begin by adding the 1 lb Sauerkraut to the slow cooker, spreading it evenly across the bottom. I rinse and drain mine first to remove excess brine, which prevents the final dish from becoming too salty.
Scatter the 1 whole Yellow Onion, thinly sliced, over the sauerkraut. Then add the 1 whole Granny Smith Apple, peeled, cored, and diced, distributing it evenly. This combination creates a sweet-tart foundation that complements the sausage beautifully.
Step 2: Add the Aromatics and Seasonings
In a small bowl, mix the 2 tbsp Brown Sugar, 1 tsp Caraway Seeds, 1 tbsp Dijon Mustard, and 3 cloves Garlic Cloves, minced finely. Caraway is traditional in this dish, adding a warm, earthy note.
Pour this mixture over the sauerkraut, onion, and apple in the slow cooker. Tuck the 1 whole Bay Leaf and 4 pieces Juniper Berries (lightly crushed) into the layers. Finish with 0.5 tsp Black Pepper for subtle heat.
Step 3: Nestle the Sausage and Add Broth
Arrange the 1.5 lb Polish Sausage, sliced into rounds, on top of the sauerkraut mixture. I use kielbasa for its smoky, garlicky flavor, which pairs perfectly with the tangy sauerkraut.
Pour the 1 cup Chicken Broth over everything, ensuring the liquid pools at the bottom. This helps steam the sausage and keeps the dish moist during the long cooking process. Low-sodium broth is preferred to control the saltiness.
Step 4: Slow Cook to Perfection
Cover the slow cooker and set it to Low for 6-7 hours or High for 3-4 hours. The dish is done when the sausage is heated through and the flavors have melded together.
You’ll know it’s ready when the sauerkraut is tender and the sausage has absorbed the sweet, tangy, and aromatic notes from the other ingredients. Stir once halfway through cooking to redistribute the flavors evenly.
Pro Tips For Making Polish Sausage And Sauerkraut Recipe Crock Pot
- Brown the Sausage: I learned this the hard way—searing the kielbasa for 2-3 minutes per side before adding it to the crock pot builds a depth of flavor that simmering alone just can’t.
- Rinse the Kraut: Skip the can juice or your dish will taste harsh; a quick rinse under cold water removes excess salt without washing away the tang.
- Low and Slow: Resist the urge to crank the heat—4 hours on low in the crock pot keeps the sausage juicy and lets the apple melt into the sauerkraut just right.
- Add Apple Late: Toss in the diced Granny Smith during the last 30 minutes so it softens but still holds its shape and bright acidity against the rich sausage.
Storing and Reheating This Dish
Refrigerator Storage
Let this dish cool for no more than 2 hours before transferring to airtight containers. I use glass Pyrex with snap-on lids to preserve freshness. It stays delicious in the fridge at 40°F or below for up to 4-5 days. The flavors deepen overnight, making leftovers even better. ❄️
Freezer Storage
For longer storage, freeze in quart-sized freezer bags for up to 3 months. Squeeze out excess air to prevent freezer burn and leave 1 inch of headspace for expansion. Label with the date—I like using Sharpie markers for this.
Stovetop Reheating
This is my preferred method. Transfer to a heavy-bottomed pot, add ¼ cup chicken broth or water, and heat over medium-low heat for 10-15 minutes. Stir occasionally to prevent sticking. Taste and adjust seasoning with a pinch of salt if needed.
Microwave Reheating
For quick meals, microwave individual portions covered with a damp paper towel. Heat on 70% power for 2-3 minutes, stir, then continue in 1-minute intervals until reaching 165°F. Add a splash of broth if it looks dry. 🔥

Frequently Asked Questions
Can I use pre-cooked smoked sausage instead of kielbasa?
Yes, any smoked sausage works well. Just ensure it’s good quality—avoid varieties with excessive fillers. The flavor will be slightly different but still delicious.
Should I rinse the sauerkraut before using?
Rinsing removes excess brine and prevents the dish from becoming too salty. Drain well after rinsing for the best texture and flavor balance.
What if I don’t have caraway seeds?
You can omit them, but they add traditional flavor. For a substitute, try ½ tsp fennel seeds or ½ tsp cumin for a similar earthy note.
Can I cook this on high heat to save time?
Yes, set the crock pot to High for 3-4 hours. The flavors develop best on Low for 6-7 hours, but high works in a pinch.
