This dish makes good use of a short grocery list. The potatoes soak up the smoky cooking juices, while the kraut keeps each bite bright. It feels hearty without needing a thick sauce.
- Simple prep: Slice, chop and layer everything right in the crock.

- Total Time: 7 hours 20 minutes–8 hours 20 minutes on LOW; 4 hours 20 minutes–5 hours 20 minutes on HIGH
- Slow Cooker Size: 6-quart oval slow cooker
Ingredients:
- 1 1/2 lb fully cooked smoked pork kielbasa, refrigerated and thawed, cut into 1/2-inch-thick rounds
- 2 lb Yukon Gold potatoes, scrubbed, skin on, cut into 1-inch chunks
- 24 oz sauerkraut, weighed after draining, not squeezed dry
- 1 medium onion, diced (about 1 cup)
- 3/4 cup low-sodium chicken broth
- 2 tablespoons unsalted butter, cut into small pieces
- 1 tablespoon Dijon mustard
- 1 tablespoon packed brown sugar
- 1/2 teaspoon caraway seeds
- 1/2 teaspoon ground pepper
Choose kielbasa labeled fully cooked, rather than fresh raw Polish sausage. Yukon Gold potatoes hold their shape well. Drain the kraut in a strainer; if you prefer less tang, rinse it briefly before draining and weighing. Skip added salt because both the sausage and kraut supply plenty.

How to Make Crockpot Kielbasa, Sauerkraut & Potatoes
Keep the potato pieces even so they soften at the same pace.
Step 1: Prep the Sausage and Vegetables
Cut 1 1/2 lb fully cooked smoked pork kielbasa into 1/2-inch-thick rounds.
Scrub 2 lb Yukon Gold potatoes and cut them into 1-inch chunks, leaving the skins on.
Dice 1 medium onion (about 1 cup).
Step 2: Layer the Crock
Place the 2 lb potato chunks in the bottom of a 6-quart oval slow cooker, then scatter the 1 medium diced onion over them.
Spread 24 oz drained sauerkraut over the onion and arrange the 1 1/2 lb kielbasa rounds on top.
Stir 1 tablespoon Dijon mustard, 1 tablespoon packed brown sugar, 1/2 teaspoon caraway seeds and 1/2 teaspoon ground pepper into 3/4 cup low-sodium chicken broth in a measuring cup.
Pour the broth mixture evenly over the layers.
Dot the top with 2 tablespoons unsalted butter, cut into small pieces.
Step 3: Slow Cook Until Tender
Cover and cook on LOW for 7–8 hours or HIGH for 4–5 hours.
Keep the lid closed until the lower end of the cooking range, then check a potato from near the center; it should be easy to pierce all the way through with a fork.
If the potatoes resist the fork, cover and continue cooking, checking in 30-minute intervals; acidic sauerkraut and different slow cookers can lengthen the timing.
Check that the sausage and center of the dish reach 165°F (74°C) as a conservative reheating target for this fully cooked sausage meal.
Gently fold the layers together once the potatoes are tender, keeping most chunks intact.
The finished dish should have soft kraut, juicy sausage and thin, pale-gold buttery cooking juices, rather than thick gravy.
Step 4: Plate and Serve
Divide the kielbasa, potatoes and sauerkraut among 6 plates, with a little cooking liquid spooned over each portion.
Serve with optional sliced rye bread to soak up the juices.
Why This Recipe Works (Quick Science)
Gentle, covered cooking softens the onion and lets the smoky sausage flavor spread through the broth. Yukon Gold potatoes have enough starch to lightly enrich the juices while holding their shape. Butter adds a smooth finish without turning the broth into a heavy sauce.
Sauerkraut adds acid, which can slow potato softening. Small, even chunks placed closest to the heat help, but a fork test matters more than the clock. The brown sugar softens the sharp edge of the kraut without making the dish taste sweet.
Common Mistakes to Avoid
- Using raw sausage: This method is written for fully cooked smoked kielbasa.
- Cutting large potatoes: Oversized chunks may stay firm long after the sausage is heated.
- Adding extra liquid: The kraut and onion release moisture. Too much broth makes the meal soupy.
- Lifting the lid often: Each peek lets heat escape and can delay dinner.
- Stirring too hard: Tender potatoes can break down into mash.
- Salting at the start: Taste first; the sausage and kraut already bring salt.
What to Serve With Crockpot Kielbasa, Sauerkraut & Potatoes
Sliced rye bread is a natural match for the smoky sausage and tangy kraut. It also soaks up the buttery broth. For a fresher side, add a simple cucumber salad or plain green salad. The potatoes already provide the starch, so you do not need rice or noodles.
Substitutions and Variations
- Milder kraut: Briefly rinse the sauerkraut, drain well, then measure the drained weight.
- Different sausage: Use the same weight of fully cooked smoked turkey kielbasa. The flavor and fat content will change.
- No caraway: Leave it out if you dislike its earthy, anise-like flavor.
- Less sweet: Omit the brown sugar for a sharper finish.
Leftovers and Storage
Divide leftovers into shallow covered containers and refrigerate within 2 hours, or 1 hour if the room is above 90°F (32°C). Keep refrigerated for 3–4 days. Freeze for up to 2 months for best quality; thaw in the refrigerator. Potatoes may become softer after freezing.
Reheat in a covered saucepan or microwave, adding a splash of broth if needed, until the center reaches 165°F (74°C). Use the stove or microwave for reheating rather than the slow cooker.

Frequently Asked Questions (FAQ)
Q: Do I need to brown the kielbasa first?
A: No. Fully cooked smoked kielbasa can go straight into the crock. It stays plump and moist without a fried crust.
Q: Can I use fresh Polish sausage?
A: Use fully cooked smoked kielbasa for this recipe. Fresh raw sausage needs its own cooking method and safety checks.
Q: Should I rinse the sauerkraut?
A: Rinsing is optional. Drain it as written for a stronger tang, or rinse briefly for a milder flavor. Weigh it after draining either way.
Q: Why are my potatoes still firm?
A: Large pieces, acidic kraut and a cooler-running slow cooker can all delay softening. Keep cooking with the lid on and check again in 30 minutes.
Q: Can I peel the potatoes?
A: Yes. Keep the same weight and chunk size. Peeled potatoes may break apart a little more easily when stirred.
Q: Is there supposed to be liquid in the bottom?
A: Yes. This meal has a small amount of thin, buttery broth. It should moisten the food without covering it like soup.
Q: Can I double the recipe?
A: Use a larger cooker only if the doubled batch fits within the maker’s recommended fill level. Do not pack a double batch into the same 6-quart cooker. Timing may change.
Q: Can I make it ahead?
A: You can chop the onion and sausage the night before and refrigerate them separately. Cut the potatoes just before loading the cooker. Assemble and start cooking when you are ready.
Q: Can I leave it on WARM all day?
A: Avoid a long hold, which can split the sausage and break down the potatoes. Follow your cooker’s holding instructions and keep the food at 140°F (60°C) or above.
