Smoky kielbasa, tangy sauerkraut, and buttery baby potatoes simmer together in the crockpot until every bite tastes deeply savory with a bright edge. Garlic, Dijon, and smoked paprika (plus a few caraway seeds, for that rye-bread note) melt into the broth and fill the kitchen with a cozy, old-world aroma that beats any drive-thru. Spoon it into bowls, scatter on fresh parsley, and set out crusty bread for mopping up the juices.

Why Make Crockpot Polish Sausage, Sauerkraut and Potatoes?

Because it delivers slow-cooked comfort with almost no effort: just layer everything in the pot and let time do the work. Thick-sliced kielbasa stays juicy, while baby potatoes hold their shape and soak up the garlicky, mustard-kissed broth. Draining the sauerkraut keeps its tang bright instead of overpowering, and a splash of melted butter rounds out the flavor. Smoked paprika and a pinch of caraway add depth that tastes like it simmered all day, and a handful of fresh parsley stirred in at the end lifts the whole bowl. It feeds six, reheats beautifully for up to 3 days, and is exactly the kind of homemade meal that makes drive-thru dinners feel forgettable.

The Ingredients That Make It Work

Simple ingredients get the best results when each one is chosen with care. Here is what every item brings to this Crockpot Polish Sausage, Sauerkraut and Potatoes, plus a few tips for getting it right.

The Hearty Base

• Polish kielbasa (1½ lbs / 680 g) : This is the smoky, savory backbone of the dish. Look for a fully cooked, good-quality kielbasa with visible seasoning and a firm snap, and slice it into thick pieces (about ¾ inch) so it stays juicy through the long cook. Smoked turkey sausage works as a lighter swap.
• Baby potatoes (2 lbs / 900 g) : Their waxy texture holds up to slow cooking and soaks up the broth without turning mushy. Yukon gold, red, or mixed baby potatoes all work well. Quarter them into evenly sized pieces so they finish cooking at the same time.
• Sauerkraut (1½ lbs / 680 g) : This adds the tangy, bright contrast that balances the rich sausage. Refrigerated sauerkraut in a bag or jar usually has a crisper bite and fresher flavor than canned. Drain it well for a pleasant tang, or give it a quick rinse for a milder dish.

The Aromatics

• Onion (1 medium) : Onion adds gentle sweetness that softens the sauerkraut’s sharpness as it cooks down. A yellow onion is the most reliable choice, and a medium dice helps it melt into the broth.
• Garlic (3 cloves) : Fresh garlic brings warm, savory depth that mellows beautifully over a slow cook. Mince it fresh when you can, since jarred garlic can taste flat or slightly sour after hours in the pot.

The Liquids and Flavor Builders

• Chicken broth (1 cup) : The broth creates the savory cooking liquid that infuses the potatoes. Choose low-sodium, since kielbasa and sauerkraut already bring plenty of salt. Vegetable broth is a fine substitute.
• Unsalted butter (3 tablespoons, melted) : Butter adds richness and rounds out the sauerkraut’s acidity. Unsalted keeps you in control of the final seasoning. Olive oil can stand in if needed, though the flavor will be slightly less cozy.
• Dijon mustard (1 tablespoon) : Dijon adds a subtle tang and gentle heat that brightens the broth and complements the sausage. Smooth Dijon blends in best, but whole-grain mustard also works for a more rustic texture.

The Seasonings

• Smoked paprika (1 teaspoon) : It adds earthy smokiness and a warm, rosy color that makes the dish look as good as it tastes. Check that the label says “smoked,” because sweet paprika won’t give the same depth.
• Dried thyme (1 teaspoon) : Thyme adds a woodsy, herbal note that holds up well in slow cooking, where dried herbs release their flavor gradually. Rub it between your fingers as you add it to wake up the aroma.
• Caraway seeds (1 teaspoon, optional) : These give the signature rye-bread flavor that pairs so well with sauerkraut and pork-based sausage. For the best aroma, crush the seeds lightly before adding them, or skip them if you aren’t a fan.
• Black pepper (½ teaspoon) : Pepper adds mild heat and a little bite to balance the richness. Freshly ground pepper has a livelier flavor than pre-ground.
• Salt (½ teaspoon, or to taste) : Salt is a finishing adjustment here, since the sausage, broth, and sauerkraut all contribute their own. Taste the dish near the end of cooking before adding more.

The Finishing Touch

• Fresh parsley (2 tablespoons, chopped) : Parsley adds a fresh, grassy lift and a pop of color against the rich, savory bowl. Flat-leaf (Italian) parsley has the best flavor. Stir it in just before serving so it stays vibrant.

Step-by-Step Instructions

• Whisk the chicken broth, melted butter, Dijon mustard, smoked paprika, dried thyme, caraway seeds, and black pepper together in a medium bowl until smooth. Set the bowl aside while you build the layers.
• Spread the quartered baby potatoes across the bottom of a 6-quart crockpot, then scatter the diced onion and minced garlic over them. I like to put the potatoes at the bottom because they sit closest to the heat and cook through evenly.
• Arrange the thick-sliced kielbasa over the onion and garlic in a single, loose layer. This keeps the sausage juicy as it slowly renders its smoky flavor into the pot.
• Pile the well-drained sauerkraut on top of the sausage, then pour the broth mixture evenly over everything. You don’t need to stir, since the liquid will work its way down as it heats.
• Cover and cook on LOW for 6 to 7 hours or on HIGH for 3 to 4 hours, until the potatoes pierce easily with a fork but still hold their shape. I keep the lid closed during cooking, because every peek lets out heat and adds 15 to 20 minutes.
• Stir gently to bring the potatoes, sausage, and sauerkraut together, then taste the broth and add up to ½ teaspoon salt if it needs it. It’s normal if the broth looks a little thin at first, because it thickens slightly and gets more flavorful as it rests.
• Fold in the chopped fresh parsley and let the pot sit uncovered for about 5 minutes. I usually spoon it into warm bowls with plenty of broth and set out crusty bread for mopping up the juices.

Tip: For deeper flavor, sear the kielbasa slices in a hot skillet for 2 to 3 minutes per side until browned before layering them in. It’s an extra step, but the caramelized edges add a savory richness.

Reminder: Let leftovers cool, then store them in an airtight container in the refrigerator for up to 3 days. Reheat gently with a splash of broth.

Variations & Substitutions

This recipe is forgiving, so bend it around your pantry, your diet, or whatever you’re craving. These tweaks keep the cozy, tangy character of the dish intact.

• Add sweet apple : Stir in one peeled, chopped Granny Smith apple with the onion; its gentle sweetness softens the sauerkraut’s tang and complements the pork sausage.
• Go lower-carb : Swap the potatoes for equal weight in cubed turnips or rutabaga, which stay firm through slow cooking and cut the carbs.
• Turn up the heat : I swap half the kielbasa for fully cooked andouille and add ¼ teaspoon red pepper flakes when I want a spicier pot.
• Make it dairy-free : Swap the butter one-to-one with olive or avocado oil, and check your kielbasa label for milk or dairy fillers to keep it dairy-free.
• Try a vegetarian spin : Use plant-based smoked sausage added for the last hour, vegetable broth, and a drained can of white beans for heartiness.
• Stretch with veggies : Layer in two sliced carrots with the potatoes for natural sweetness, or top with two cups chopped green cabbage for a stew-like feel.

Serving Suggestions

• Serve it in warm, shallow bowls: Use a slotted spoon to scoop up the potatoes, kielbasa, and sauerkraut, then ladle some broth over the top so every bowl gets plenty of the garlicky, mustard-kissed liquid. Finish with a pinch of fresh parsley and a small dollop of Dijon on the side for anyone who wants extra tang. Warming the bowls first keeps the potatoes hot, which matters because this dish is best steaming.
• Add something crusty and something crisp: Crusty bread is a must for mopping up the broth. I like rye or a sourdough boule with softened butter, since it echoes the caraway in the pot. Because this Crockpot Polish Sausage, Sauerkraut and Potatoes is rich and tangy, a cool side helps balance it. A creamy cucumber-dill salad or a crunchy apple slaw adds freshness, and roasted carrots or green beans add a little sweetness against the sauerkraut.
• Pour a drink that matches the smokiness: A crisp Pilsner or lager is the classic choice, because its clean bitterness cuts through the kielbasa’s richness. For wine, a dry Riesling or Grüner Veltliner works well, since their acidity and light fruitiness suit the smoked paprika and mustard. For a non-alcoholic option, I like cold sparkling apple cider.
• Match the serving style to the occasion: For a weeknight dinner, bowls at the table with bread are all you need. For game day or a casual get-together, set the crockpot to WARM and let guests serve themselves with a ladle, bread, and small bowls of mustard and parsley. Leave the parsley off the pot itself until the last minute so it stays bright.

Tips for the Best Hearty Crockpot Polish Sausage, Sauerkraut and Potatoes

• Drain sauerkraut thoroughly : Press it in a colander first so excess brine doesn’t flood the broth and make the potatoes taste sharply sour.
• Sear the kielbasa : I brown the slices 2 to 3 minutes per side before layering. The caramelized edges add a savory depth the slow cooker can’t create.
• Cut potatoes evenly : Quarter the baby potatoes into similar-sized pieces so they all turn fork-tender together, instead of some staying firm while others crumble.
• Crush the caraway : Bruise the seeds with the flat of a knife before whisking them into the broth. This releases far more of that rye-bread aroma.
• Season at the end : Kielbasa, sauerkraut, and broth all carry sodium, so I use low-sodium broth and add salt only after tasting the finished pot.

Make-Ahead Tips for Crockpot Polish Sausage, Sauerkraut and Potatoes

Busy weeknights are exactly why this Crockpot Polish Sausage, Sauerkraut and Potatoes is such a lifesaver for meal prep! You can slice the kielbasa, quarter the potatoes, and dice the onion and garlic up to 24 hours in advance, then refrigerate them in separate airtight containers (submerge the cut potatoes in cold water to prevent browning, and drain well before using). Whisk the broth, butter, Dijon, and spices together and chill that too, so it’s ready to pour. In the morning, simply layer everything in the crockpot, cook as directed, and stir in the parsley before serving. You’ll get slow-cooked comfort that’s just as delicious, with almost no morning effort.

Storage & Freezing

• Refrigerating: Cool the pot for no more than 2 hours, then pack leftovers into airtight containers with plenty of broth, which keeps the potatoes and kielbasa from drying out. Your Crockpot Polish Sausage, Sauerkraut and Potatoes will keep for up to 3 days in the fridge. The caraway, smoked paprika, and sauerkraut tang deepen overnight, so day two often tastes even better. Don’t leave the food sitting in the ceramic insert, because it holds heat too long and cools too slowly to be safe.
• Freezing: Freeze portions for up to 2 months in freezer-safe containers, leaving about an inch of headspace for the broth to expand. The kielbasa and sauerkraut freeze beautifully. The baby potatoes soften and can turn slightly grainy, though waxy varieties like Yukon gold or red hold up far better than russets. I stop the cook as soon as a fork slides in easily if I know a batch is headed for the freezer. I also leave out the fresh parsley and stir it in after reheating, since frozen parsley turns dark and limp.
• Thawing: Thaw frozen portions overnight in the refrigerator rather than on the counter. The butter in the broth may separate a little after freezing, but a good stir brings it back together.
• Reheating: Warm leftovers in a saucepan over low to medium-low heat, stirring gently, until steaming hot (165°F / 74°C). Add a splash of chicken broth if the liquid has reduced. In the microwave, heat in 60-second bursts and stir between each so the potatoes don’t turn rubbery. Skip the crockpot for reheating, since it warms too slowly to get cold food through the safe temperature range. Finish with fresh parsley and a small spoonful of Dijon if the flavor has gone flat.
